On papermaking waste water Treatment process debugging

XX Paper Factory in Xi'an, Shaanxi Province uses waste paper to make paper. The sewage discharged by the factory has high SS content, low BOD5/COD ratio and is not easy to be biochemical. Shallow air flotation/contact oxidation was used to treat waste paper papermaking wastewater (treatment scale: 4000m3/d). After one and a half months of microbial cultivation, acclimation, contact film formation, the commissioning effluent quality reached GB3544-

coking waste water Treatment process explain

Coking wastewater mainly comes from the following sources: water entrained by coal, reaction generated water, steam and fresh water added for distillation and washing of coking products, wastewater condensed or separated after contacting with gas and product water, including residual ammonia water composed of gas collector spray separation liquid and primary cooling liquid; Ammonia rich water for ammonia washing in ammonia water process. These two parts of wastewater are discharged after ammonia evaporation (recovery). In sulfur ammonia process

printing and dyeing waste water Treatment process progress

The daily discharge of printing and dyeing wastewater in China is (300~400) × 104t, which is one of the largest polluters in various industries. Printing and dyeing wastewater is mainly composed of desizing wastewater, scouring wastewater, bleaching wastewater, mercerizing wastewater, dyeing wastewater and printing wastewater. It has the following characteristics: large amount of water, high content of organic pollutants, large changes in alkalinity and pH value, and large changes in water quality; Biochemical performance
