Zhejiang Wastewater Treatment Plant, Longyou County, Zhejiang Province

The Zhejiang wastewater treatment plant is located in Longyou County, part of Quzhou City in Zhejiang Province, China. Serving a population of 100,000, it is a medium-sized facility supporting the region's urban wastewater management needs. The plant is situated in the溪滩 area of Longzhou Subdistrict, reflecting its role in treating municipal sewage from the county. As a facility in China, the plant operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For a plant of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially if discharging into sensitive water bodies. Regulatory compliance is expected. The treated wastewater likely discharges into local rivers within the Qiantang River basin, which flows into the East China Sea. This watershed supports diverse aquatic life and is important for regional agriculture and drinking water sources. The plant's operation helps protect downstream water quality and ecosystem health.

The plant discharges into the Qiantang River basin, which flows through Zhejiang Province and empties into the East China Sea near Hangzhou Bay. This watershed supports diverse aquatic ecosystems, including fish spawning grounds and migratory bird habitats. The region's dense population and industrial activity place pressure on water quality, making effective treatment crucial for maintaining ecological balance and downstream water uses.
