Overview
The Shaanxi wastewater treatment plant serves Xianyang, Shaanxi, China, with a population equivalent of 120,000. It discharges into the Wei River, a tributary of the Yellow River.
The Shaanxi wastewater treatment plant is located in Xianyang, Shaanxi Province, China, serving a population of approximately 120,000. The facility is situated near the Yangling Wei River Bridge in the Yangling District, an area with significant agricultural and industrial activity. As a plant serving a medium-sized agglomeration, it is expected to meet the standards set by China's national wastewater discharge regulations, which require secondary treatment as a minimum. Typical facilities in this region employ biological treatment methods to reduce pollutants before discharge. The treated effluent is discharged into the Wei River, a major tributary of the Yellow River. This water body is ecologically important, supporting diverse aquatic life and providing water for irrigation and industrial use downstream. The plant plays a crucial role in protecting the Wei River and the broader Yellow River basin from untreated wastewater pollution.
Environmental context
The plant discharges into the Wei River, which flows into the Yellow River, ultimately reaching the Bohai Sea. The Wei River is a key water source for agriculture and industry in the region, and its water quality is critical for downstream ecosystems. The plant's operations help reduce nutrient and pollutant loads, supporting the ecological health of the river and the sensitive coastal environment of the Bohai Sea.
Frequently asked questions
The plant is located in the Yangling District of Xianyang, Shaanxi Province, China, near the Yangling Wei River Bridge.
The plant serves a population equivalent of approximately 120,000 people.
The treated wastewater is discharged into the Wei River, a major tributary of the Yellow River.
In China, wastewater treatment plants are regulated under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for pollutants based on the receiving water body's sensitivity. Plants serving over 100,000 people are typically required to achieve at least secondary treatment with nutrient removal.
For a plant of this size in China, secondary biological treatment is standard, often including activated sludge processes. In environmentally sensitive areas, tertiary treatment may be required to further reduce nitrogen and phosphorus.
