Description
Technical field
The present invention relates to industrial wastewater innoxious process for treating field, the Coal Chemical Industry being related specifically to a kind of economical and efficient is given up
Water tackling method.
Background technology
Coal Chemical Industry refers to coal as raw material, makes coal be converted into gas, liquid and solid product or half through chemical process
Finished product, is then further processed into the industry of chemical industry, energy products.China's richness coal, the energy resource structure of oil-poor, few gas determine coal
Developing rapidly of chemical industry, especially New Coal Chemical Industry.Traditional coal chemical industry refers to coal gasification, liquefaction, coking and Jiao
Oil processing, carbide acetylene chemical industry etc., also include with coal for waste carbon materials and coal based high molecular material etc..Novel coalification
Work is leading with coal gasification, including ammonia from coal, acetic acid, dimethyl ether etc..Coal chemical industry brings while developing rapidly
Relatively overall situation problem.This is because, the technological process of production of coal chemical industry is many and complicated, water consumption is huge, causes this process
Middle wastewater discharge is very big, and waste water produced by it is that a kind of COD COD is high, ammonia-nitrogen content is high, colourity is high and turbidity
High waste water, containing poisonous and harmful substances such as a large amount of phenol, cyanogen, oil, ammonia nitrogens.In comprehensive wastewater, CODcr is typically left at 5000mg/l
The right side, ammonia nitrogen are at 200 ~ 500mg/l.Easily biodegradable organics in waste water is mainly phenolic compound and benzene-like compounds；Arsenic coughs up,
Naphthalene, furan, narrow azole and belong to degradable type organic；The Organic substance of difficult degradation mainly has arsenic pyridine, carbazole, biphenyl, terphenyl etc..
If these pollutant are discharged in environment, ecological environment and health can be caused high risks, therefore coal gasification waste water
Process, the most at home and abroad coal chemical industrial waste water process field receives much concern
The technology of current domestic process coal chemical industrial waste water mainly has biochemical process: biochemical process is to the phenol in waste water and benzene class material
There is a preferable removal effect, but to some hardly degraded organic substance treatment effects such as quinolines, indoles, pyridines, carbazoles relatively
Difference so that the outer draining CODcr of coal chemical industry is difficult to reach primary standard.Coal chemical industrial waste water exists again after biochemical treatment simultaneously
(because of the Organic substance containing various chromophores and auxochrome, such as 3-methyl isophthalic acid, 3,6 heptantrienes, 5-drop for colourity and the highest feature of turbidity
Bornylene-2-carboxylic acid, 2-chloro-2-norborene, 2-hvdroxv-benzofuran, phenol, 1-mesyl-4-methylbenzene, 3-methyl
Benzothiophene, naphthalene-1,8-diamidogen etc.).Therefore, reuse or discharge standard are reached, mainly after this type of coal gasification waste water be processed
Reduce the indexs such as CODcr, ammonia nitrogen, colourity further.
Additionally, the conventional treatment method of coal chemical industrial waste water also has Ozonation: the method is the most senior as one
Oxidation technology, because of its strong oxidizing property and disinfecting power, has a wide range of applications in Water purification.But, owing to ozone is water-soluble
Property is poor, and utilization rate is low, has the shortcomings such as selectivity to pollutant, affects its further commercial introduction and application.As for absorption
Method, is to have solute and the ability of colloid in absorption water based on the surface of solids, when waste water passes through the solid particle that specific surface area is the biggest
Time, the pollutant in water are adsorbed on solid particle (adsorbent), thus remove polluter and realize.The method can obtain
Preferably effect, but it is big to there is adsorbent amount, costly produces secondary pollution problems, is generally adapted small scale wastewater treatment
Application.
It is that first kinds of pollution matter kind is many, the high concentrated organic wastewater of complicated component based on coal chemical industrial waste water, depends merely on traditional
Single method processes, it tends to be difficult to reach discharge standard.For the process of this waste water, it is commonly divided into coagulation, at two grades
Reason and advanced treating.Coagulation i.e. pretreatment, mainly includes the methods such as coagulation, chemical precipitation, air supporting, to remove part lime-ash
And oils, and the valuable materials such as the phenols in waste water and ammonia nitrogen are recycled；Two stage treatment is mainly biochemical treatment, main
A/O, A2/O, SBR, UASB to be included etc. and some emerging technique；Deep treatment method mainly has electrochemical process, coagulating sedimentation
Method, advanced oxidation processes, membrane separation process and absorption method etc..But, this type of technique equally exists problems with: 1) biodegradation
Thorough, the foam of generation is many, will carry out froth breaking by new water in a large number, but weak effect；2) operation is run and daily management requires height,
It is difficult to stably reaching standard discharge；3) chemical feeding quantity is big, and operating cost is high；4) water outlet is difficult to meet the water inlet index of ultrafiltration and reverse osmosis,
Recycle water standard can not be reached.
