Overview
Hunan wastewater treatment plant serves Zhangjiajie, Hunan, China, with a population of 162,700. It operates under China's national wastewater standards, ensuring proper treatment before discharge.
The Hunan wastewater treatment plant is located in the Baotagang community, Chongwen Street, Yongding District, Zhangjiajie City, Hunan Province, China. It serves a population of approximately 162,700, placing it in the medium-to-large agglomeration category under Chinese wastewater management frameworks. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to achieve at least secondary treatment, with some requiring advanced treatment to meet local water quality targets. Regulatory expectations for this population tier suggest robust treatment infrastructure. The plant discharges treated effluent into local water bodies within the Lishui River basin, which flows into Dongting Lake and eventually the Yangtze River. This downstream chain supports diverse aquatic ecosystems and provides water for agriculture and urban use downstream.
Environmental context
The plant's treated effluent enters the Lishui River system, a tributary of Dongting Lake, which is a major floodplain lake connected to the Yangtze River. This watershed supports a variety of fish species and migratory birds, and the lake plays a crucial role in flood regulation and water supply for the region. The plant's discharge quality is critical to maintaining ecological balance in this sensitive aquatic environment.
