Description

Technical Field

[0002] Coking wastewater is an industrial wastewater from the high-temperature distillation of coal, gas purification and chemical product refining process. It contains a variety of toxic, harmful and organic substances. Its composition is very complex, mainly including residual ammonia water, phenol water, gas condensate and wastewater generated by refined chemical products. Residual ammonia water contains pollutants such as ammonia, cyanide and sulfide; phenol water comes from the coal tar separation process in the gas purification process, containing phenols, benzene and other difficult-to-degrade organic matter; coal gas condensate contains pollutants such as ammonia, phenol, sulfide; wastewater generated by refined chemical products contains various chemical substances such as acrylonitrile, toluene, xylene, etc.; Since coking wastewater contains a large amount of toxic, harmful and difficult-to-degrade substances, it pollutes the environment. In order to cope with this problem, researchers and developers have developed a variety of treatment technologies, including physical methods (such as precipitation, filtration, flotation, etc.), chemical methods (such as chemical precipitation, oxidation, reduction, etc.), biological methods (such as activated sludge method, biofilm method, etc.) and various combined processes.
