Run-green (Figure) _ _ integrated wastewater treatment equipment sewage treatment equipment provided by the Environmental Protection Engineering Co., Ltd. Shanxi Runtong. Run-Environmental Engineering Co., Ltd., Shanxi (www.sxruntong.com) is a professional, "sewage treatment, waste gas treatment, dust handling" of the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to participate in healthy competition in the market, so that the "Run Tong" brand has a good reputation. We adhere to the "service first, customers first" principle, so Runtong environmental won the trust of customers in the public sewage treatment equipment, and establish a good corporate image.

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 sewage treatment equipment, suspected carcinogen. Aromatic hydrocarbons and aromatic amines, etc. Similarly, there are many biologically active substances. Phthalocyanine vinegar class is another class of carcinogens hospital wastewater sewage treatment equipment, including 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 sewage treatment facilities, recovery of 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. Sewage treatment which can be divided according to their role in accordance with its role in three sewage treatment can be divided into three physical, biological and chemical methods. ① Physical methods: The main advantage of the physical effects of the non-separated effluent dissolved substances in the process does not change the chemical properties. Conventional gravity separation, centrifugal separation, reverse osmosis, flotation and the like. Treatment physical structure is relatively simple, economical, large towns and villages for water capacity, strong self-purification capacity, sewage treatment less demanding degree. ② biological method: the use of microbial metabolism, the sewage was dissolved or colloidal state of decomposition of organic matter is oxidized to stable inorganic substances, sewage purification. Commonly used activated sludge and biofilm. Biological treatment level is higher than the physical law. ③ chemical method: the role of chemical reactions to disposal or recycling colloidal substances dissolved substances or methods of sewage, used for industrial wastewater. Commonly used coagulation method, neutralization, oxidation-reduction, ion exchange method. Treatment effects of chemical treatment, high costs, and more for the water after biochemical treatment, further treatment to improve water quality.
