Abstract
The invention relates to a biological carrier for treating sewage and an application of the biological carrier. The biological carrier is characterized by being prepared from the following materials in percentage by mass: 80-85% of regenerated plastic grains as the main ingredient as well as 6-10% of zinc oxide, 2-3% of polyving alcohol and 4-7% of glycerinum as the auxiliary materials. Isolating walls and guide plates are additionally arranged in a biochemical pool of a sewage treatment plant, an original large pool is divided into a plurality of small pools, stopping nets are additionally arranged in the small pools, the biological carrier is fed according to the ratio of 25-35% to the volume of the stopping nets, and corresponding equipment is additionally arranged inside the pools, so that the biological carrier is in the fluidization state in the sewage in the pools, and the biological loading quantity is 40g/L; and as the equipment is solidly combined with the biological carrier, the biologic carrier has small possibility of dropping off, the service life is more than 20 years, and the biologic carrier is good in elimination effect on various pollutants, particularly when being used for eliminating ammonia nitrogen.
Description
Technical field
The invention belongs to sewage Prevention Technique field, be specifically related to dispose of sewage with bio-carrier and application thereof.
Background technology
Domestic pollution is the main emission source of ammonia nitrogen, and it is the Main Means that ammonia nitrogen is cut down that town sewage is processed, and will become the main field that ammonia nitrogen reduces discharging.At present, China's water environment pollution situation is heavier, and permanganate index, five-day BOD and ammonia nitrogen still are main contamination index.Sewage treatment facility can not satisfy the requirement that ammonia nitrogen reduces discharging, the early stage sewage work that builds of part, at the beginning of building, only consider the removal of chemical oxygen demand (COD), do not have nitrification function, the ammonia control technology generally comprises and set up biologic packing material in reaction tank, improves the biomass in the reaction tank or set up BAF after settling tank, the water outlet ammonia nitrogen is higher, how these sewage works are carried out upgrading, make it to remove ammonia nitrogen, it is problem anxious to be resolved that the performance ammonia nitrogen reduces discharging usefulness.
Summary of the invention:
The object of the invention is to avoid the deficiencies in the prior art to provide a kind of disposes of sewage with bio-carrier and application thereof, under the prerequisite that does not change original sewage treatment structure size of main body, utilize the biomembrance process of microbial immobilized technology, with a large amount of microorganisms fixing on carrier, form microbial film, increase the load of microorganisms amount, thereby remove various pollutents in the sewage.
For achieving the above object, the technical scheme that the present invention takes is: a kind of disposing of sewage used bio-carrier, and it is characterized in that being prepared from by the material of following mass percent: major ingredient is recycled plastic granules 80-85%; Auxiliary material is zinc oxide 6-10%, polyvinyl alcohol 2-3%, glycerine 4-7%;
Its preparation method comprises the steps:
(1) sub-elects qualified recycled plastic granules with separator;
(2) major ingredient and auxiliary material are mixed by said ratio, stirred 5-8 minute through high speed proportioning machine, low speed proportioning machine;
(3) hot melt 10-15 minute, the control temperature was 200-250 ℃, and compound is melted fully;
(4) according to profile and the dimensional requirement of customer need, extrude with forcing machine;
(5) Vacuum shaping;
(6) dicing machine blank, packing.
This carrier profile is tubulose, and pipe is interior, pipe adheres to some thorns outward.
Dispose of sewage with the application of bio-carrier, it is characterized in that: in sewage work's biochemistry pool, increase partition wall and flow deflector, original Da Chi is divided into some small-sized ponds body, in Xiao Chi, add catch net, in catch net, by the ratio of the volume 25-35% bio-carrier of the present invention of batching, and in the pond, set up relevant device so that bio-carrier becomes fluidized in the sewage in the pond.
The invention has the beneficial effects as follows: low take waste or used plastics as raw materials cost, changing carrier manufacturing process compression molding is extrusion molding, make microbe carrier automatically form the inside and outside quick-fried thorn of pipe under in air, acting on, be beneficial to microorganic adhesion, make the biological load amount reach 40g/L, be combined with carrier firmly, difficult drop-off, reach work-ing life more than 20 years, to the removal of various removal of pollutants better effects if, particularly ammonia nitrogen in the sewage.
Embodiment:
Below principle of the present invention and feature are described, institute only gives an actual example and to be used for explaining the present invention, is not the scope of the present invention for restriction.
Embodiment 1: a kind of disposing of sewage used bio-carrier, and it is characterized in that being prepared from by the material of following mass percent: major ingredient is recycled plastic granules 85%; Auxiliary material is zinc oxide 7%, polyvinyl alcohol 3%, glycerine 5%;
Its preparation method comprises the steps:
(1) sub-elects qualified recycled plastic granules with separator;
(2) major ingredient and auxiliary material are mixed by said ratio, stirred 5 minutes through high speed proportioning machine, low speed proportioning machine;
(3) hot melt is 15 minutes, and the control temperature is 200 ℃, and compound is melted fully;
(4) according to profile and the dimensional requirement of customer need, extrude with forcing machine;
(5) Vacuum shaping;
(6) dicing machine blank, packing.
This carrier profile is tubulose, and pipe is interior, pipe adheres to some thorns outward.
Dispose of sewage with the application of bio-carrier, it is characterized in that: in sewage work's biochemistry pool, increase partition wall and flow deflector, original Da Chi is divided into some small-sized ponds body, in Xiao Chi, add catch net, in catch net, by the ratio of volume 30% bio-carrier of the present invention of batching, and in the pond, set up relevant device so that bio-carrier becomes fluidized in the sewage in the pond.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
