Overview
Zhejiang wastewater treatment plant serves Jinyun County, Zhejiang, China, with a population of 98,000. The facility operates under China's national wastewater discharge standards.
The Zhejiang wastewater treatment plant is located in Jinyun County, Lishui City, Zhejiang Province, China. It serves a population of approximately 98,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. The plant operates under China's national discharge standards (GB 18918-2002) which mandate secondary treatment for urban wastewater. For agglomerations of this scale, tertiary treatment may be required if the receiving water body is designated as sensitive. The plant discharges into local waterways that ultimately drain into the East China Sea via the Oujiang River system. Its operations contribute to protecting downstream aquatic ecosystems and maintaining water quality in the densely populated Yangtze River Delta region.
Environmental context
The plant's treated effluent flows into the Oujiang River basin, which drains into the East China Sea. This coastal watershed supports diverse aquatic life and is important for regional fisheries. The area experiences a subtropical monsoon climate with high seasonal rainfall, making effective wastewater treatment critical to prevent eutrophication and protect downstream marine habitats.
