Overview
Zhejiang wastewater treatment plant serves Suichang County in Lishui, Zhejiang Province, China. It treats wastewater for a population of 5,000, operating under China's national wastewater standards.
The Zhejiang wastewater treatment plant is located in Suichang County, part of Lishui City in Zhejiang Province, China. It serves a small population of approximately 5,000 residents, reflecting its role in a smaller urban or peri-urban community within the region. As a plant serving fewer than 10,000 people, it falls under China's regulatory framework for small-scale wastewater treatment. Chinese standards require such facilities to meet the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates at least secondary treatment to protect receiving water bodies. Typical small plants in this region use biological treatment methods such as activated sludge or sequencing batch reactors. The plant discharges treated effluent into local water bodies that ultimately drain into the Oujiang River basin, which flows eastward into the East China Sea. This watershed supports agricultural irrigation and freshwater ecosystems, making proper treatment essential for maintaining water quality and preventing eutrophication in downstream coastal areas.
Environmental context
The plant's treated effluent enters local streams that feed into the Oujiang River system, which flows through Zhejiang Province and discharges into the East China Sea near Wenzhou. This coastal watershed supports diverse aquatic life and provides water for agriculture and fisheries. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but nutrient loading from wastewater can still affect downstream estuarine and coastal ecosystems if treatment is inadequate.
Frequently asked questions
