Overview
Shandong wastewater treatment plant serves Liangshan County, Jining, Shandong, China, with a population equivalent of 140,000. It operates under China's national wastewater discharge standards.
The Shandong wastewater treatment plant is located in Liangshan County, Jining City, Shandong Province, China. It serves a population equivalent of 140,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, approximately 50 km from the coast, and discharges into local water bodies that ultimately drain into the Yellow Sea. 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 areas. The plant likely employs biological treatment (e. g. , activated sludge) to comply with national effluent limits for COD, BOD, ammonia, and phosphorus. The plant's receiving water body is part of the Yellow River basin, which flows into the Bohai Sea. The downstream environment supports diverse aquatic life and is ecologically sensitive due to agricultural runoff and industrial discharges in the region. Proper treatment at this plant helps protect water quality in the lower Yellow River and the Bohai Sea ecosystem.
Environmental context
The plant discharges into the Yellow River basin, which flows through Shandong Province and empties into the Bohai Sea. This watershed supports important fisheries and migratory bird habitats. The Bohai Sea is a semi-enclosed water body with limited water exchange, making it vulnerable to nutrient pollution. Effective wastewater treatment is critical to prevent eutrophication and protect marine biodiversity in this ecologically sensitive coastal zone.
Frequently asked questions
