Receiving range: All industrial and domestic sewage in Zhongtang Industrial Park

Process route: The main technique is: grid + lifting pool + aerobic pool + a sinking tank + secondary sedimentation tank + chemical reaction pool + activated carbon filter

Acceptance Criteria: Tianjin municipal standard "Integrated Wastewater Discharge Standard" DB12/356-2008

Treatment capacity: 5000 Ton/day

Effect: The WWTP has been jointly operated by a company from Beijing and Tianjin. However, the water quality has not been consistently up to standard, and the cumulative number of over-acceleration exceeded 273 in 2016. After our company took over the operation, by improving the existing process and sewage treatment equipment, its effluent has been stable with 100% qualified output water, which has made outstanding contributions to the lifting of the restricted batch in Zhongtang Town. It has been recognized by the municipal environmental supervision team and highly praised by the leaders of the Binhai New Area.
