Shaanxi Wastewater Treatment Plant, Yulin, Shaanxi Province, China

The Shaanxi wastewater treatment plant is located in Shenmu City, part of Yulin City in Shaanxi Province, China. It serves a population of approximately 126,800, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated inland, away from coastal areas, and its operations are governed by China's national discharge standards. 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 water bodies. The regulatory framework ensures that plants of this scale typically employ biological treatment methods such as activated sludge or sequencing batch reactors. The plant discharges treated effluent into local water bodies within the Yellow River basin, which ultimately flows into the Bohai Sea. The receiving environment supports agricultural irrigation and industrial water use downstream. Proper treatment is critical to prevent eutrophication and protect aquatic ecosystems in the region.

The plant discharges into the Yellow River basin, which flows through northern China and empties into the Bohai Sea. This watershed supports diverse aquatic life and is a vital water source for agriculture and industry. Downstream ecosystems are sensitive to nutrient pollution, making effective wastewater treatment essential for maintaining water quality and ecological balance.
