Overview
Shaanxi wastewater treatment plant serves 28,400 people in Zhendan County, Yan'an, Shaanxi, China. It operates under China's national wastewater standards for inland facilities.
The Shaanxi wastewater treatment plant is located in Zhendan County, part of Yan'an City in Shaanxi Province, China. It serves a population of 28,400, classifying it as a medium-sized agglomeration under Chinese municipal wastewater management. The facility is situated inland, far from coastal areas, and discharges into local water bodies within the Yellow River basin. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For plants serving populations between 10,000 and 100,000, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the sensitivity of the receiving water body. Regulatory compliance is expected. The plant's treated effluent likely enters a tributary of the Yellow River, which flows through the Loess Plateau region. This area is ecologically sensitive due to high sediment loads and seasonal water scarcity. Proper treatment is essential to protect downstream water quality and aquatic habitats in the Yellow River basin.
Environmental context
The plant discharges into a tributary of the Yellow River, which flows through the Loess Plateau before reaching the Bohai Sea. The region faces challenges from soil erosion and agricultural runoff, making effective wastewater treatment critical for maintaining water quality. The downstream environment supports diverse aquatic life and provides water for irrigation and drinking water supplies in downstream provinces.
