Overview
Shandong wastewater treatment plant serves 130,000 people in Sishui County, Jining, Shandong, China. It operates under China's national wastewater standards for medium-sized agglomerations.
The Shandong wastewater treatment plant is located in Sishui County, Jining City, Shandong Province, China. It serves a population of approximately 130,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated near the Sihe River, a tributary of the Nansi Lake system. As a facility serving over 100,000 people, 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 water bodies. Typical plants of this scale in Shandong employ activated sludge processes with biological nitrogen and phosphorus removal to comply with local environmental requirements. The plant discharges treated effluent into the Sihe River, which flows into Nansi Lake, the largest freshwater lake in northern China. Nansi Lake is a critical water source for the South-to-North Water Diversion Project and supports diverse aquatic life, including migratory birds and fish species. The plant plays a key role in protecting downstream water quality in this ecologically and economically important watershed.
