Shanxi Wastewater Treatment Plant - Jincheng, Shanxi Province, China

The Shanxi wastewater treatment plant is located in Beishidian Town, Chengqu District, Jincheng City, Shanxi Province, China. It serves a population equivalent of approximately 42,000 people, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. As a Chinese municipal plant, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and heavy metals. 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, a major river system in northern China. The Yellow River supports agricultural irrigation, industrial use, and ecological flows, making effective wastewater treatment critical for downstream water quality and ecosystem health.

The treated effluent from the Shanxi plant enters local streams that flow into the Yellow River basin, one of China's most important water systems. The Yellow River provides water for millions of people and extensive agricultural areas downstream. Effective nutrient removal is essential to prevent eutrophication in the river and its reservoirs, which support diverse aquatic life and migratory bird populations.
