Description
Technical field
The present invention relates to a kind of Coagulation and Adsorption agent, particularly relate to the agent of a kind of coking chemical waste water Coagulation and Adsorption, meanwhile, the invention still further relates to the purposes of this coking chemical waste water Coagulation and Adsorption agent.
Background technology
Coking chemical waste water is that coal hot procedure produces, and from the coal washing in process of coking, quenching, byproduct processing and the link such as refining, also has effluent part to produce in gas purification and Chemicals removal process simultaneously.Coking chemical waste water source has: the remained ammonia waste liquid that (1) coal Pintsch process and raw gas cooling produce, this is primary discharge source, coke-oven plant, waste discharge water yield Zhan Quan factory of institute quantity discharged over half, its water quality is complicated, constituent species is various and Pollutant levels are higher, except containing inorganic pollution beyond the region of objective existences such as ammonia, cyanogen, thiocyanates, also containing phenol, oils, naphthalene, pyridine, quinoline, anthracene and other condensed-nuclei aromatics compound etc., be one of current more unmanageable waste water; (2) gas final cold device and the draining of crude benzol separator tank etc. in gas purification process, contained pollutent is phenol, cyanogen and other COD component etc., containing ammonia and Pollutant levels are relatively low; (3) draining of coal tar, refining benzene and other technological process, contained pollutent is phenol, cyanogen and other COD component etc., and the water yield is less, and Pollutant levels are lower.Coking chemical waste water is because ature of coal is different, product is different, the different wastewater property difference that causes of production technique is large, and complicated component, containing a large amount of difficult degradation inorganics, organism and hazardous and noxious substances, wherein inorganics mainly exists with the form of ammonium salt, comprises (NH
