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 remaining ammonia, which is produced out of the dry distillation of coal and gas in the cooling water, which accounts for more than half of the total amount of water wastewater, a major source of coking wastewater; the second is in the gas purification process arising out of 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, containing a large amount 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, which dimethyl phthalate, di-iso-octyl phthalate is detected EPA priority pollutants. In short, the ingredients coking wastewater complex, a wide range of pollutants, 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 method has positive significance . 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 the depth of hospital sewage treatment equipment, it is the secondary treatment of water further processing, so as to effectively remove contaminants in water of different nature. Many people know the sewage is: turbid water is sewage. In fact, is not comprehensive integrated wastewater treatment equipment for sewage, GB has clearly defined. Xiao Bian today as we speak effluent standards under division. In GB, the drainage is divided into three criteria, namely the national standard level, the national standard two, three national standard, national standard level is divided into an A and level B, the water discharge standards may be different regulations in the country, there are requirements two, and some require three, of course, there are no provisions in force areas exist. China has not yet heard of the city drainage standards prescribed for a sewage treatment equipment, sewage treatment situation of Shanghai is the best city, is also only plan to existing sewage treatment plants all transformed into a B standard. Water sewage treatment is how to divide it, there are five general inspection standards, COD, BOD, SS, NH3-N, TP, COD: Chemical oxygen demand BOD: Biochemical Oxygen Demand SS: suspended particles NH3-N: ammonia Content TP: phosphorus content of an A --COD: 50, BOD: 10, SS: 10 a B - COD: 60, BOD: 20, SS: 20 two --COD: 100 sewage treatment equipment, BOD : 30, SS: 30 three --COD: 120, BOD: 60, SS: 50
