- Abstract:
- The design capacity of a wastewater treatment plant in a chemical industry park in Weifang City, Shandong Province, is 10 000 m3/d, including 5 000 m3/d of pharmaceutical and other chemical wastewater and 5 000 m3/d of non-chemical wastewater. The designed effluent quality is first level A in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The wastewater is treated separately according to quality. The combined process of Fenton pre- oxidation, pulse hydrolysis acidification， two stage AO and MBR is adopted for chemical wastewater, and the combined process of pretreatment, AAO biochemical, and triple sedimentation tank is adopted for non-chemical wastewater. The project has good treatment effect and stable effluent quality since its operation in January 2014.
