Shandong Wastewater Treatment Plant, Pingyi County, Shandong Province, China

The Shandong wastewater treatment plant is located in Pingyi County, Shandong Province, China. It serves a population equivalent of 210,000, classifying it as a large agglomeration under Chinese regulatory frameworks. The plant is situated in an inland area, approximately 50 km from the coast, and its treated effluent likely discharges into local rivers that eventually reach the Yellow Sea. As a large-scale facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. Typical facilities of this size employ activated sludge processes with biological nutrient removal to comply with national standards. The plant plays a critical role in protecting local water bodies in the Yi River basin, which drains into the Yellow Sea. By treating wastewater from Pingyi County, it reduces pollutant loads that could otherwise impact downstream aquatic ecosystems and coastal waters. The facility supports public health and environmental sustainability in the region.

The plant discharges into the Yi River system, a tributary of the Huai River basin, which ultimately flows into the Yellow Sea. The downstream environment includes agricultural areas and ecologically sensitive wetlands that support diverse aquatic life. Effective treatment is essential to prevent eutrophication and protect water quality in the receiving waters.
