Overview
Shanxi wastewater treatment plant serves Changzhi, Shanxi province, China, with a population equivalent of 62,000. It operates under China's national wastewater discharge standards.
The Shanxi wastewater treatment plant is located in Lucheng District, Changzhi City, Shanxi Province, China. It serves a population equivalent of 62,000, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes with biological nutrient removal to meet Class 1A or 1B effluent standards. The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin via the Qin River or its tributaries. This watershed supports agricultural irrigation and industrial water use in Shanxi, a region with water scarcity challenges. Proper treatment is critical to protect downstream water quality and aquatic ecosystems.
Environmental context
The plant's receiving water body is part of the Yellow River basin, specifically the Qin River system, which flows through Shanxi and Henan provinces before joining the Yellow River. The Yellow River is a major water source for northern China, supporting agriculture, industry, and domestic use. Downstream ecosystems include wetlands and riverine habitats that rely on adequate water quality. The region faces seasonal water scarcity, making effective wastewater treatment essential for maintaining ecological balance and preventing eutrophication.
