Overview
Shanxi wastewater treatment plant serves Changzhi, Shanxi Province, China, with a population equivalent of 36,400. It operates under China's national wastewater discharge standards.
The Shanxi wastewater treatment plant is located in Dan Shun Community, Zhangzi County, Changzhi City, Shanxi Province, China. It serves a population equivalent of 36,400, classifying it as a medium-sized municipal facility within the region. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set effluent limits for conventional pollutants and nutrients. Plants of this scale typically employ biological treatment processes such as activated sludge or oxidation ditch to meet Class 1A or 1B standards, depending on the receiving water body's sensitivity. The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin. The surrounding region is part of the Loess Plateau, where water resources are scarce and pollution control is critical for protecting downstream aquatic ecosystems and agricultural water use.
Environmental context
The plant's treated effluent flows into tributaries of the Yellow River, which is the second-longest river in China and a vital water source for northern China. The Loess Plateau watershed is ecologically sensitive due to high sediment loads and seasonal water scarcity. Downstream environments include agricultural areas and the Yellow River estuary, which supports diverse aquatic life and migratory bird populations.
