- Abstract:
- The capacity of phase Ⅱ project of Yangquan wastewater treatment plant was 80 000 m3/d. The effluent quality implements the strict value of the first level A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002)and class Ⅴ water quality standard of Environmental Quality Standards for Surface Water (GB 3838-2002). The project adopts the BARDENPHO biological treatment process with strong shock load resistance and strong nitrogen and phosphorus removal function. The process flow is BARDENPHO biological treatment+mixed reaction sedimentation tank+cloth filter+disinfection, and the sludge treatment adopts mechanical dewatering process. The biological treatment adopts multi-point water distribution and multi-point reflux measures. The sewage is divided into pre-anoxic zone and anaerobic zone respectively. The sludge returns to the pre-anoxic zone and mixes with a certain proportion of influent water, which greatly enhances the ability of nitrogen and phosphorus removal. The project was put into operation in 2017, and the effluent quality stably reached the design standard.
