Leather industry is based on animal skins (cattle, pigs, sheep, etc.) as raw materials.During processing, a large number of proteins and fats to waste slag, but also to join a large number of chemical raw materials: acid, alkali, salt, sodium sulfide, carbon, chrome tanning agent, fatliquoring agent, dye, etc.In addition to part is absorbed, most into the waste water.Therefore, the characteristics of tanning waste water pollution degree is high, contains a lot of organic matter, inorganic matter and suspended solids, with color and smell, and the toxicity is bigger.If do not take reasonable effective treatment process, make the waste stabilization, will cause serious pollution to water environment.
　　The company according to the characteristics of the leather industry wastewater, refer to all kinds of pollution treatment technology at home and abroad, combined with the practice of company experience, developed a set of advanced tanning wastewater treatment process.Technology strategy is to waste classified collection, preprocessing, classification mixed processing again.The biggest characteristic is to use mature technology, strong operability and low operating cost of pollution treatment technology;Optimization of various design parameters reasonably, make effluent standards;The company original (A/O) n biochemical treatment process, to ensure stable COD standard.

　　Technological process:
　　Comprehensive wastewater collection -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- pretreatment (A/O) n biochemical treatment -- -- -- -- -- national standards
　　Hair removal sulfur-containing wastewater -- -- -- -- -- collection -- -- -- -- -- -- pretreatment into comprehensive wastewater treatment
　　Chrome tanning waste water collection -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- pretreatment into comprehensive wastewater treatment
　　After the process treatment, stable water discharging standard.Processing system adopts the one-piece structure, process flow, layout reasonable, beautiful appearance, cover an area of an area small;A high degree of automation, convenient operation, stable running, save manpower material resources.
