Abstract
The invention discloses a novel method which adopts phenol-water coal-slime to dispose of phenol contained wastewater contamination. As the increase of coal chemical production load, the quantity of phenol contained wastewater rises continuously, and draining the phenol water to rivers causes contamination and storing the phenol water in pools cannot completely solve contamination as the water quantity is too large. The method of the invention includes that firstly the phenol contained wastewater is collected, wherein, A. the phenol contained wastewater is filtered through membrane filtrationto raise the concentration thereof and to drain clean water so as to reduce the volume of phenol contained wastewater; B. the concentrated water is mixed with slack coal so as to be made into the phenol-water coal-slime; C. the phenol-water coal-slime is transited to a fluidized-bed boiler by using a coal-slime transit technique for combustion disposal so as to disintegrate and combust the high-concentration phenol contained wastewater in the boiler; D. the energy obtained through combustion is output as heat energy or electricity powder. The invention is suitable for the decontamination treatment to the phenol contained wastewater and the treatment to wastewater containing organic oxide, organic cyanide, aromatic hydrocarbon and derivatives thereof.
Description
Technical field:
The present invention relates to a kind of pollution, the new process that carries out innoxious thorough improvement to the phenol wastewater that produces in the Coal Chemical Industry process.
Background technology:
The gasification of coal is one of main technique in the coal chemical industry enterprises.Several popular gasification furnaces have at present: airflow bed gasification furnace, fluidized-bed gasification furnace and moving bed pressurized-gasification furnace.Wherein the moving bed pressurized-gasification furnace is domesticized preferably in China.Representing the type of furnace is lurgi gasifier and PKM stove, and China uses the producer of moving bed pressurized-gasification furnace a lot of now, and the platform number of each producer's operation is also a lot.For example, Yunnan chemical fertilizer factory of PLA is 9; Shanxi chemical fertilizer factory is 5; Harbin Gas Works is 5; The Yima gasification plant is 3.But also some chemical enterprise intends adopting this type of furnace.
This type of furnace uses lump coal as raw material, and the coal charge that enters coal stove is divided into two parts, promptly excellent coal and smut.In order to produce satisfactory coal for gasification, raw coal must be through broken and screening, and the piece rate that goes out of excellent coal is generally 40%, and the piece rate that goes out of smut is 27%, like this, has produced a large amount of fine coal in the lump coal production process; Simultaneously in order to reduce into the stove pit ash, satisfy the production of gasification furnace, smut must be through washing, in the coal washing process, produced a large amount of black waters again, black water is concentrated, the press filtration meeting has produced a large amount of coal slimes, has produced a large amount of fine coal and coal slime like this in the production process of going into the stove coal that gasifies.The open-air spontaneous combustion of piling up easy initiation coal of a large amount of fine coal and coal slime causes the waste of resource and the pollution of environment, if to sell at a low price, again enterprise has been caused great economic loss.
In producing in the Gas Production, the raw gas of generation need cool off in washer and wash, and makes that most dust and tar are separated to get off.In the process of washing and cooling, just produced phenol wastewater.Because the gasifying agent of this type of furnace is made up of pure oxygen and steam.Water vapour can not decompose (resolution ratio is 37.5%) fully in gasification, does not have the steam that decomposes and the moisture of coal self, condensation in the coal gas cooling procedure and become phenol water.In the circulation cleaning process of coal gas, produce residue.That is phenol water can not all be used to recycle, and a large amount of residue phenol water is arranged, suitable height of phenol concentration and complicated component in the residue phenol water.Concrete condition is as shown in table 1.
Phenol concentration in the table 1 moving bed pressurized-gasification furnace waste water
Along with the increase of producing load, the phenol wastewater amount also constantly increases.The type of furnace of this gasification furnace has determined the certainty of a large amount of phenol water generates.Phenol wastewater is all harmful to human body and other animals and plants.Just formed pollution in the rivers water if phenol wastewater entered.If phenol wastewater is stored in the pond, its water yield is excessive and fail the fundamentally problem of contaminated solution.Will administer from point of view of environment protection for the improvement of phenol wastewater is instant problem.
Harbin Gas Works was once attempted multiple phenol wastewater pollution control technology, the serious phenol pollution problem of all failing thoroughly to solve.The most up-to-date techniques of phenol wastewater pollution control have following method.
(1) CO
2Supercritical extraction technique
The pilot scale that lasts 10 days, result of the test show, hanging down under the pH value, and overcritical can effectively part unit phenol and polyhydric phenols in the high-concentration phenolic wastewater being extracted, but to consume a large amount of soda acids; For the lower waste water of phenol content, its effect of extracting also is limited, to total phenol clearance in 20%.
(2) water supercritical oxidation technology
About 86%, but because the operating condition harshness, operating pressure is at 250kg/cm to the clearance of unit phenol and polyhydric phenols
2, operating temperature is at 400 ℃, and makees oxidant with hydrogen peroxide, and (PH=2～3) require highly to equipment material under acid condition, and investment is estimated 10 about hundred million, and the operating cost height is difficult to realize industrialization.
(3) catalytic wet oxidation
Pilot plant test through 7 days catalytic wet oxidations, the clearance of total phenol can reach 90%-95%, this technology requires harsh to equipment, must adopt titanium material alloy material, equipment investment is expected to be 200,000,000 yuan, and catalyst is invested 0.75 hundred million yuan, and life of catalyst is about 3 years, operating cost is high, is not suitable for industrialization.
(4) on-catalytic void tower oxidation technology
If adopt this technology, plant investment is estimated 1.4 hundred million yuan, and 6.15 yuan/ton of cost of sewage disposal, but need biochemical device further to handle can qualified discharge, and so not only investment is big, and the operating cost height.
(5) the resin treatment Technology of Sewage of the Ge De of Nanjing University company
Resin regeneration will consume a large amount of soda acids, causes processing cost too high, is difficult to carry out.
(6) embrane method is handled waste water
The clean source in Harbin Gas Works and Henan film is handled company and is inquired into regard to the coal gas waste of Harbin Gas Works, preliminary treatment can guarantee film water inlet requirement, but a part of concentrate of process film need go back to extraction workshop section carries out reextraction, find through overtesting, some organic matter is inextractable in the middle of the phenol water, the result causes the enrichment in system of this part organic matter, finally can't handle, so Harbin Gas Works has been abandoned embrane method.
In sum, above method all has weak point separately, all can not the pollution problem of effectively thorough solution phenol.Through science thinking and test, we propose a kind of improvement method of brand-new phenol wastewater, i.e. phenol water coal slime method.This method can fundamentally solve the coal chemical industry enterprises phenol wastewater and administer this difficult problem of a specified duration and unsettled.
Summary of the invention:
