Overview
Shandong wastewater treatment plant serves Weishan County, Shandong, China, with a population of 140,000. It operates under China's national wastewater standards.
The Shandong wastewater treatment plant is located in Weishan County, part of Jining City in Shandong Province, China. It serves a population of approximately 140,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater regulations. As a plant of this scale, it is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Typical facilities in this region employ biological treatment methods such as activated sludge or A2O processes to achieve required effluent quality. The plant discharges treated wastewater into local water bodies that ultimately drain into the Nansi Lake system, the largest freshwater lake in northern China. This lake is part of the Huai River basin and plays a critical role in regional water supply, flood control, and biodiversity. Proper treatment is essential to protect the lake's ecological health and downstream communities.
Environmental context
The plant's treated effluent flows into the Nansi Lake watershed, which is part of the larger Huai River basin. Nansi Lake is a vital freshwater resource supporting fisheries, agriculture, and drinking water for millions. The lake also serves as an important stopover for migratory birds along the East Asian-Australasian Flyway. Effective wastewater treatment is crucial to prevent eutrophication and maintain water quality in this ecologically sensitive region.
