Run-Environmental Engineering Co., Ltd., Shanxi Coking wastewater treatment outlined coking coking wastewater, gas at high temperature carbonization, purification and by-product recovery process, resulting in volatile phenol-containing industrial wastewater polycyclic aromatic hydrocarbons and oxygen, sulfur, nitrogen and other heterocyclic compounds is a high CODcr, high phenol value, high ammonia and difficult to deal with an industrial organic wastewater. There are three main sources: First, the integration of the remaining ammonia wastewater treatment equipment, which is produced out of the water in the dry distillation of coal and gas cooling, which accounted for more than half of the total quantity of wastewater, is the main source of coking wastewater; the second is arising out of the gas purification process wastewater, such as gas and crude benzene separation of the final cold water; three other occasions in wastewater and tar, crude benzene and other refined generated in the process. Coking wastewater containing a large number of refractory organic pollutants in industrial wastewater, its complex composition sewage treatment equipment, contains large amounts of phenol, cyanide, benzene, ammonia and other toxic substances, excessive coking wastewater discharge causing serious pollution to the environment. Changes in water quality and quantity of coking wastewater with a large, complex components, especially refractory organics high organic content, and high ammonia concentration. Nitrogen-containing compounds are coking plant wastewater composed of numerous and complex organic compounds. Mass spectrometer set of quinoline and certain alkyl substituents, suspected carcinogen. Aromatic hydrocarbons and aromatic amines, etc. Similarly, there are many biologically active substances. Phthalocyanine vinegar class is another class of carcinogenic substances in wastewater sewage treatment facilities in Linyi, where dimethyl phthalate, di-iso-octyl phthalate is detected EPA priority pollutants. In short, the ingredients coking wastewater complex, a wide range of pollutants sewage treatment facilities, many of which belong to the carcinogenic mutagenic effects of bioactive substances effluent COD often can not meet the national emission standards, therefore, seek effective and low-cost advanced treatment methods has a positive meaning. The degree of coking wastewater treatment can be classified according to the primary, secondary and tertiary treatment. A deal could be called primary treatment or pretreatment, by precipitation, extraction, oxidation-reduction methods such as the removal of suspended matter in wastewater, recovering valuable substances. Secondary treatment of wastewater is further treated on the basis of primary treatment. Tertiary treatment, also known as advanced treatment, it is the secondary treatment of water and then further processed, in order to effectively remove contaminants in the water of different nature. Buried sewage treatment equipment Note: (1) Office of the equipment must be installed to ensure that no rain water; outlet pipe (2) this device must be on the opposite floor 0.4m below; the top (3) shall be embossed with heavy equipment may not have been large vehicles (means no special design); (4) the internal sewage equipment generally not evacuated in order to prevent groundwater to equipment float. Sewage treatment equipment _ Run-green (certified) _ sewage treatment equipment provided by the Environmental Protection Engineering Co., Ltd. Shanxi Runtong.
