Overview
Anhui wastewater treatment plant serves 142,000 people in Lai'an County, Chuzhou, Anhui Province, China. The facility discharges treated effluent into local waterways within the Huai River basin.
The Anhui wastewater treatment plant is located in Xin'an Town, Lai'an County, under the jurisdiction of Chuzhou City in Anhui Province, China. It serves a population of approximately 142,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment standards are governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates at least secondary treatment for urban plants. For facilities serving over 100,000 people, Class 1-A or 1-B effluent standards are typically required to protect receiving water bodies. It operates under national regulations that ensure compliance with environmental protection goals. The plant discharges treated wastewater into local rivers that ultimately drain into the Huai River basin, a major water system in eastern China. The Huai River flows eastward to the Yellow Sea, supporting agriculture, industry, and ecosystems along its course. Proper treatment at this plant helps reduce nutrient and pollutant loads, safeguarding downstream water quality and aquatic habitats.
Environmental context
The plant's effluent enters local waterways within the Huai River basin, which flows through Anhui and Jiangsu provinces before reaching the Yellow Sea. The Huai River supports diverse aquatic life and is a critical water source for irrigation and drinking water. Downstream areas include ecologically sensitive wetlands and lakes that benefit from reduced pollution loads from well-operated treatment plants.
