Description

Urban and rural pipeline system engineering sewage and utilization comprehensive system structure

The invention relates to a sewage treatment pipeline system project in environmental protection and one of the most basic infrastructure facilities in urban and rural ecological environment construction, in particular to a sewage discharge system of urban and rural pipelines combined with other facilities to form a sewage system project. And the use of integrated architecture.

Background technique

With the development of urbanization and the productivity of science and technology in the world today, the vast rural material energy is too extracted, leading to the depletion of land to material energy in rural areas, and the development of desertification, while the city concentrates the material energy from rural areas for conversion. ), a large amount of waste is generated during the process of collecting and distributing, causing serious pollution of rivers (enrichment of energy of lakes and marine materials). This bipolar deterioration of the ecological environment is increasingly threatening the survival of mankind, causing great concern to all mankind, and has become a major problem in the world - this urban and rural polarization has deteriorated, the essence of which is: urban and rural materials Energy is not caused by a benign cycle.

Existing sewage treatment plants cannot solve this problem. Because it can't create a benign cycle of urban and rural material energy. This is due to the error in its overall structural design, which leads to the fundamental error of the flow of material energy. Therefore, according to the layout and method of the current sewage plant and the flow of material energy, no matter how much money is invested, how advanced science and technology can be used to improve it. The realm of a benign and large cycle of urban and rural material energy, therefore, cannot fundamentally change the problem of the deterioration of the urban and rural ecological environment to the extremes.

Water is the source of life, water is the lifeline of ecological balance, water is the omnipotent resource, and the blessing of human society is water. The deterioration of the ecological environment of human society is mainly caused by water pollution and vicious circle. The invention proposes the method of sewage treatment and the innovation of the most basic infrastructure facilities in urban and rural ecological environment construction: it is the application of comprehensive structure, comprehensive utilization and comprehensive development road, creating artificially controllable water and other material energy benign (middle And small, cyclical comprehensive structural system, an important program, method, route, direction and the most basic infrastructure facilities in urban and rural ecological environment construction to transform nature and build a beautiful ecological environment. There are three modes of sewage treatment technology at home and abroad. : Primary treatment, secondary treatment and tertiary treatment, or small-scale utilization after treatment. So far, the secondary treatment of sewage that has reached the standard has not been used in the rivers, lakes and seas. It is the sewage treated by the tertiary treatment in some advanced countries, and it is rarely used. (Even if it is used, it is scattered, sporadic, small-scale use). This traditional method can not make the sewage in the urban and rural material energy constitute a virtuous cycle, and the effect of recycling the recycling function in the closed loop is only to reduce the local pollution or transfer the pollution to it, and the energy consumption is huge. So far, there are still problems in the history of ecological and environmental science development - the current sewage treatment plant method can not achieve the urban-rural ecological balance.

The main shortcomings of current sewage treatment plants in controlling urban water pollution are:

(1) Wrong thoughts and methods; only from a single consideration, not from the overall consideration, simply governing for governance, regardless of others, so adopt centralized guidance, useless emissions, and the guiding ideology of treating the symptoms. If it is reflected in the fact that only the treatment is not considered for utilization, only the re-circulation is considered in the pipeline embedding, and the existing piping system is not considered.

(2) The technical method is wrong. First, the sewage and urban living water scattered in each factory are concentrated in the sewage treatment plant, which is inevitable in daily processing. The various components are complex and increase the processing difficulty, so the energy consumption is huge. Second, the route and location of the pipe network are wrong. Re-arranging the sewage main network system in the land road is a violation of the natural drainage system of the original urban drainage system to the river, so that the original drainage system is not fully utilized, and affects various pipeline systems and other facilities on the land, resulting in construction difficulty. Large, capital investment, and waste. ,

(3) The overall structure method is wrong; due to errors in thought methods and technical methods, it will inevitably lead to errors in the overall structure method. Due to the use of a single centralized treatment, no use of emissions, ultimately caused by rivers, rivers, lakes, 'the pollution of the oceans and the wrong path of material energy flow. The most fundamental error of this method violates the "material energy conversion (change), the law of distributed circulation", is a vicious circle. This method does not require a comprehensive structure, comprehensive utilization, and comprehensive development. It cannot constitute a benign and large circulation system of urban and rural material energy, and it cannot fundamentally prevent the current urban-rural energy conversion (changing) of the distribution cycle from deteriorating to two extremes. In general, it is not a scientific method.

(4) From the perspectives of society, economy and environment; 'The vast majority of existing sewage treatment plants at home and abroad only deal with no use, and it is a light-input and non-productive enterprise, which does not constitute a benign and large-circulating ecosystem of urban and rural material energy. It is also impossible to solve the trend and problems of the more developed social productivity and the worsening urban and rural ecological environment. Therefore, the traditional sewage treatment method is generally an unscientific method, which is a large investment, small benefits, and a temporary solution.

In summary, the current sewage treatment has the following: First, the overall design is backward, and the pipeline layout is unreasonable (the original is to discharge the sewage to the river, river, and lake. The outer pipe of the sewage plant is relocated under the road. , so that the sewage is directed to the new pipe network, collecting the flow to the sewage Water plant. Since the slope is used to promote the flow of sewage, it is necessary to build a sewage lifting station when the sewage flows through three or four kilometers, which creates a great waste. Second, there is almost no comprehensive utilization, and only simple emissions are implemented. The collection of drinking water, rivers, rivers and lakes is still a secondary pollution; the third is that it does not constitute a benign cycle of urban and rural material energy, and thus it is impossible to reverse the trend and problems of the deterioration of the urban and rural ecological environment.

'Building an invention to replace the modern sewage treatment plant work, as one of the most important social and ecological environment infrastructures connecting the urban areas of the city, constitutes the transformation of the urban and rural material energy (change), and the distribution of benign large circulation channels. As a pipe in the whole, the shape can be in the form of a circle or a square, which is caused by various materials, various structures and manufacturing methods. The sewage is treated through the integrated system of sewage and utilization of urban and rural pipeline system engineering, and the energy of water and other materials is recycled and recycled. Secondly, the application of modern science and technology, social facilities, and comprehensive structure constitutes the system engineering system of the overall three-dimensional latitude and longitude network, creating and inventing the “manually controllable urban and rural material energy (small and medium) circulation and ecosystem engineering system”. This system has been gradually built, and it can completely guide the human social ecological environment from the vicious cycle, the benign circle, the high-speed, high-efficiency, health, harmony and sustainable development. This is the direction for human beings to create an infinitely beautiful society. road'. In addition, the sewage is converted (changed) in a system, and the process of collecting and distributing the circulation is recycled to a virtuous cycle. The present invention has been constructed based on this idea.

The search for relevant data, including Chinese patents, shows that there has not been any report on the structure of the polluting and utilization of urban and rural pipeline systems to construct a benign large cycle.

Summary of the invention

In order to overcome the deficiencies of the prior art, the object of the present invention is to propose a method for integrating a sewage drainage and utilization system of urban and rural areas with other facilities into a system. Referred to as the urban and rural pipeline system engineering sewage utilization method.

X-inch agricultural toxic substances are pre-treated to meet the standards) and various residential sewers and road sewers and pipes are connected to the sewage discharge water source pipes or trenches connected to the mud on the land, rivers, lakes and lakes. Sand and suspended solids treatment wells (other patent application), the other end of the mud, sand and suspended solids treatment wells is connected to the sewage transportation pipe, so that the sewage passes through the treatment well before entering the sewage transportation pipe, and the sewage transportation pipe is buried in There are already riverbeds in the middle of the riverbed of the urban rivers or on both sides of the riverbed, and the pipe network system is formed along the river in the river network for layout, among which there are two-way, three-way and four-way pipes; a well is provided at the intersection of the pipeline; the treatment well is connected to the sewage pipe on the riverbed in a slanting direction Preferably, the angle of 60~45° is optimal; the upper end of the sewage delivery pipe is provided with an air outlet, and the upper end of the air outlet is connected with a gas pipe, and the outlet is provided at a distance of 30 to 150 meters; The gas pipe is arranged in parallel with the sewage pipe; the terminal of the sewage pipe and the gas pipe is a sewage comprehensive treatment plant (another patent application).

The sewage pipe is distributed with a domestic organic waste disposal station (applicable for patent application) on the side of the river. The organic garbage (other garbage cannot enter) of the nearby community residents is transported to the organic waste disposal station. The garbage mixed water is crushed into a slurry liquid, flows into the mud sand and suspended solids treatment well through the pipeline, and then flows into the sewage pipeline of the riverbed through the pipeline. After mixing, it is transported into the sewage pipe network to the sewage comprehensive treatment plant for conversion. Change), collection and distribution cycle motion processing.

The river can construct a "sucking sludge carrier" (a patent application) to suck the organic sludge from the river bottom into the mud, sand and suspended matter treatment wells, and then into the sewage pipeline in the riverbed through the pipeline. They are transported together to the sewage treatment plant for conversion (change) and collection and distribution cycle motion treatment. .

The invention can be constructed by constructing a public toilet at a place where the river and the road meet, where there are many people, and the manure is directly discharged into the mud and sand suspended matter treatment well, and then discharged into the sewage transportation pipeline and sent to the sewage comprehensive treatment plant. Perform conversion (change), collection and distribution cycle motion processing.

The application system of the invention: After the sewage enters the sewage comprehensive treatment plant for conversion (replacement) and collection and distribution, it is produced: 1. Agricultural application of fertilizer water; 2. Urban water for ecological environment; 3. Organic comprehensive organic fertilizer; 4. Biogas And other gases. At the other end of the sewage treatment plant, there are more than four outlets. The pump is pumped to pump the treated fertilizer water to the reservoir. The reservoir is equipped with various valves and pipes for export to various applications. The system is equipped with irrigation, breeding, cleaning, etc. Through the overall integrated layout, an application to the city from the pipeline to the green area (band), roadside and toilet, residential health services; one to the countryside for agricultural fertilizer applications; one to the biogas station, the implementation of gas supply applications .

The sewage pipe disposed along the river bed can realize unpowered transportation, which not only saves manpower and material resources, but also does not damage the road. At the same time, it can realize the separation of rainwater and sewage to ensure the ecological balance of the river water. This not only removes many construction funds and a large amount of manpower and material resources, but also does not occupy the land. The main network of the invention is buried in the riverbed, The sewage is operated under the full pipe state, and the power is mainly driven by the potential energy compressive pressure difference between the water inlet and the river bottom pipe, and then the sewage treatment plant is pumped by the water pump to pull. In addition, the additional facilities of the invention not only solve the problems of sewage treatment, domestic organic waste treatment, inland river sludge treatment, but also solve the problem of difficulty in urban urination, and create unlimited value for industrial and agricultural production, and the material energy of rural industrial and agricultural production is another The forms are transported to the city for reuse and then recycled and reused. This constitutes a new social infrastructure structure that can artificially control the transformation (change) and distribution of urban and rural material energy. Therefore, it is a direction of common development of urban and rural social, economic and environmental benefits. To create a modern ecological city, it is necessary to create a modern agro-ecological village that fits with it. At the same time, it is also the direction and road to solve the problem that the development of human society has caused the deterioration of the ecological environment to the extremes and the development of a benign and large cycle of urban and rural material energy. Therefore, the present invention not only completely manages urban rivers, lakes, marine pollution, and pollution of urban domestic organic waste, but also provides urgently needed raw materials and fertilizers for the vast rural areas. Its far-reaching significance: it points out the track, structural model, operational mechanism and direction of the future development of human society and economy. Applying this model and method is the inevitable way to reform the modern society to a higher level and a more perfect stage.
