Overview
Shaanxi wastewater treatment plant serves 20,000 people in Yan'an, Shaanxi, China. It operates under China's national wastewater standards, discharging treated effluent into local waterways.
The Shaanxi wastewater treatment plant is located in Yan'an, Shaanxi Province, China, serving a population of approximately 20,000. Situated in the northern part of the province, the plant is part of the region's municipal wastewater infrastructure, addressing the needs of a medium-sized agglomeration. As a facility in China, the plant operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent quality limits. For plants serving populations around 20,000, secondary treatment is typically required, with potential nutrient removal in sensitive areas. It is expected to comply with local environmental regulations. The treated wastewater is discharged into the Yan River, a tributary of the Yellow River, which flows through the Loess Plateau region. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry downstream. The plant's operation helps protect water quality in this important river system.
Environmental context
The plant discharges into the Yan River, which flows into the Yellow River, one of China's major river systems. The Yellow River basin is a critical water source for northern China, supporting agriculture, industry, and ecosystems. The Loess Plateau region is prone to soil erosion, and maintaining water quality is essential for downstream ecological health and human use.
