Overview
Hunan wastewater treatment plant serves approximately 300,000 people in Lengshuitan District, Yongzhou, Hunan Province, China. It operates under China's national wastewater regulations.
The Hunan wastewater treatment plant is located in Lengshuitan District, Yongzhou City, Hunan Province, China. Serving a population of approximately 300,000, it is a significant municipal facility in the region. The plant is situated in the Xiang River basin, which flows into Dongting Lake and ultimately the Yangtze River. As a large agglomeration serving over 150,000 people, the plant is expected to meet China's national discharge standards, which require secondary treatment as a minimum. China's Water Pollution Prevention and Control Action Plan and the Environmental Protection Law mandate strict effluent limits for such facilities. Typical plants of this scale employ biological treatment processes such as activated sludge. The plant discharges treated wastewater into the Xiang River system, which is a major tributary of the Yangtze River. The downstream environment includes Dongting Lake, a large freshwater lake that supports diverse aquatic life and provides critical ecosystem services. The plant's operation is crucial for protecting water quality in this ecologically important watershed.
