- Abstract:
- A wastewater treatment plant located in an industrial park in Ningxia is designed at a scale of 15 000 m3/d and adopts the process of heterogeneous catalytic oxidation, hydrolytic acidification, five-stage Bardenpho, magnetic coagulation and precipitation, pre-ozonation, biological aerating filter, denitrification deep bed filter and ozone catalytic oxidation. The wastewater treatment plant employs the overall layout of distributed and parallel operation for all related units. This enables flexible adjustment of the operating units and transcendental units in accordance with the actual water quality and water quantity, thereby meeting the removal requirements of pollutants under various operating conditions and effectively controlling the operating cost. Since its official operation in November 2022, the wastewater treatment plant has undergone phases such as low temperature in winter and low influent load. It possesses the characteristics of shock load resistance and excellent treatment performance, and the effluent quality can meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).
