Overview
Hubei wastewater treatment plant serves Nanzhang County, Xiangyang, Hubei, China, with a population of 112,000. It operates under China's national wastewater standards for medium-sized agglomerations.
Hubei wastewater treatment plant is located in Nanzhang County, Xiangyang, Hubei Province, China. It serves a population of 112,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. As a plant of this scale, it 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. Typical facilities of this size employ activated sludge processes with biological nitrogen and phosphorus removal. The plant discharges into local waterways within the Han River basin, which flows into the Yangtze River and ultimately the East China Sea. Its operation is critical for protecting downstream aquatic ecosystems and supporting regional water quality goals.
Environmental context
The plant discharges into tributaries of the Han River, a major tributary of the Yangtze River. The Han River basin supports diverse aquatic life and provides water for agriculture and industry. Downstream, the Yangtze River flows into the East China Sea, a productive marine ecosystem. Effective treatment at this plant helps reduce nutrient loading and protect downstream water quality.
