Technology introduction
Papermaking industrial wastewater has three categories, namely: 1,pulp wastewater, 2, intermediate stage wastewater of Pulp washing, screening, bleaching,etc working stage,3, papermaking wastewater. The components of papermaking wastewater are very complicated, it has high content of organic matter and Suspended solids, it is belong to organic wastewater that is hard to be Biodegradation.
TL company has many years experience of papermaking wastewater treatment, according to the the different wastewater of papermaking, select the proper treatment technology. The typical patent products has: 1. the treatment equipment for white water of Commodity pulp and papermaking Patent Number: 201120498692.9, this operation of technology is simple, fully automatic control, lower cost, less dosage of flocculant and coagulant 2. the treatment equipment for wastewater of APMP pulping. Patent Number:201220144727.3, this technology has lower energy consumption with good effect of treatment.

Typical Technological process
① sewage inlet→grille→Collecting well→fine sieve→spare pool→adjustable pool→Cyclone reactor→Efficient shallow air flotation→clean water pool→recycling or discharge
② sewage inlet→ the primary settling pool→Shallow air flotation→cooling tower→UASB Sludge bed→Hydrolysis acidification pool→the intermediate stage of settling pool→CASS Biochemical pool→ the second settling pool→The deep oxidation of clarifier→reach the standard of discharge
