Overview
Hunan wastewater treatment plant serves Qidong County in Hunan Province, China, with a population of 132,000. It operates under China's national wastewater regulations.
The Hunan wastewater treatment plant is located in Qidong County, Hengyang City, Hunan Province, China. It serves a population of approximately 132,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is part of the municipal infrastructure for the region. As a facility serving over 100,000 people, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This regulation sets effluent limits for biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients. Typical facilities of this scale employ activated sludge or similar biological processes. The plant discharges treated wastewater into a local water body that ultimately drains into the Xiang River, a major tributary of the Yangtze River. The Xiang River flows through Hunan Province and supports diverse aquatic life and agricultural activities. Proper treatment is essential to protect downstream water quality and ecosystems.
Environmental context
The plant's treated effluent enters a local watercourse that flows into the Xiang River, which is part of the Yangtze River basin. The Xiang River supports fisheries, irrigation, and drinking water supplies for communities downstream. The region's subtropical climate with seasonal rainfall means that pollutant loads can vary, making consistent treatment important for maintaining river health and preventing eutrophication in downstream lakes and reservoirs.
