Overview
Hunan wastewater treatment plant serves Xiangyin County in Hunan Province, China, with a population equivalent of 106,000. The facility discharges into local waterways under China's national wastewater regulations.
The Hunan wastewater treatment plant is located in Wenxing Subdistrict, Xiangyin County, Yueyang City, Hunan Province, China. It serves a population equivalent of 106,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated inland, approximately 50 km from the coast, and its treated effluent likely discharges into the Xiang River system, which flows into Dongting Lake and ultimately the Yangtze River. 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 Plants (GB 18918-2002). This national regulation sets effluent limits for biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients. The plant's operational context aligns with China's broader efforts to improve water quality in the Yangtze River basin through the Water Pollution Prevention and Control Action Plan. The receiving water body is part of the Xiang River watershed, a major tributary of the Yangtze River. This region supports diverse aquatic life and provides water for agricultural and industrial use downstream. The plant's discharge contributes to the ecological health of Dongting Lake, a large freshwater lake that serves as a critical flood storage area and biodiversity hotspot in central China.
Environmental context
The plant discharges into the Xiang River system, which flows into Dongting Lake and then the Yangtze River. Dongting Lake is a vital wetland that supports migratory birds and fish species, and it plays a key role in flood regulation. The downstream Yangtze River is ecologically sensitive, hosting endemic species such as the Chinese sturgeon and finless porpoise. Nutrient loading from wastewater can contribute to eutrophication in Dongting Lake, making effective treatment essential for preserving water quality and aquatic habitats.
