A photovoltaic enterprise wastewater denitrification project

時間:2018-01-26

The total nitrogen of wastewater in a photovoltaic enterprise is as high as 1,250 mg/L, which does not meet the new total nitrogen pipe standard of the environmental protection department and cannot be directly discharged into the sewage treatment station.

According to the actual situation of the plant, our company designed the Anbang denitrification process independently developed by our company, and designed the daily treatment wastewater 500t/d.

The effluent quality of the PV wastewater treatment plant is stable and the system is running well. It fully meets the requirements of the environmental protection department of the region, and the wastewater is directly discharged into the sewage treatment station.
