Coking wastewater treatment process

>Detailed description of coking wastewater treatment process coking wastewater treatment company Coking wastewater treatment process Coking wastewater treatment company
The most professional coking wastewater treatment company is Hebei Jisheng Environmental Engineering Co., Ltd. Coking wastewater is industrial wastewater containing volatile phenols, polycyclic aromatic hydrocarbons, oxygen, sulfur, nitrogen and other heterocyclic compounds produced during high-temperature carbonization, purification and by-product recovery of coking and coal gas. It is a kind of high phenolic value and high ammonia nitrogen. A kind of industrial organic wastewater that is difficult to treat. There are three main sources: first, residual ammonia, which is wastewater produced during coal carbonization and gas cooling. Its water volume accounts for more than half of the total coking wastewater and is the main source of coking wastewater; second, it is produced during the gas purification process. Wastewater, such as gas final cooling water and crude benzene separation water, etc. The third is wastewater generated in the refining process of tar, crude benzene, etc. and other occasions.
Jisheng Environmental Company explains to you that coking wastewater is industrial wastewater containing a large amount of refractory organic pollutants. Its composition is complex and contains a large amount of toxic and harmful substances such as phenol, cyanogen, benzene, and ammonia nitrogen. Coking wastewater discharged in excess of the standard is harmful to The environment causes serious pollution. Coking wastewater has the characteristics of large changes in water quality and quantity, complex composition, high content of organic matter, especially refractory organic matter, and high ammonia nitrogen concentration.
Nitrogen-containing compounds are numerous and complex organic compounds in coking plant wastewater. Quinoline and certain alkyl substituents determined by mass spectrometry are suspected carcinogens. Aromatic hydrocarbons and aromatic amines also have many biologically active substances. Phthalate esters are another type of carcinogen in wastewater. Among them, dimethyl phthalate and diisooctyl phthalate are also priority pollutants detected by the US Environmental Protection Agency. In short, the composition of coking wastewater is complex and there are many types of pollutants, many of which are biologically active substances that can cause carcinogenesis. The effluent often fails to meet national discharge standards. Therefore, it is of positive significance to seek effective and low-cost advanced treatment methods.
Coking wastewater treatment can be divided into primary, secondary and tertiary treatment according to the degree of treatment. Primary treatment can be called primary treatment or pretreatment, which removes suspended solids in wastewater and recovers valuable substances through precipitation, extraction, oxidation and reduction, etc. Secondary treatment is the further treatment of wastewater on the basis of primary treatment. Tertiary treatment is also called advanced treatment. It further treats the secondary treated water to effectively remove pollutants of different properties in the water.
