Zhejiang Wastewater Treatment Plant, Cixi, Zhejiang Province, China

The Zhejiang wastewater treatment plant is located in Cixi City, within Zhejiang Province, China. It serves a population of 410,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a major facility in a densely populated region, the plant is expected to meet the requirements of China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving over 100,000 people. The plant likely employs activated sludge or similar biological processes to achieve compliance. The treated effluent is discharged into local waterways that ultimately drain into the East China Sea. The region's watershed supports diverse aquatic life and is important for fisheries and agriculture. Proper treatment is critical to prevent eutrophication and protect downstream ecosystems.

The plant discharges into the local river network that flows into Hangzhou Bay and the East China Sea. This coastal watershed supports important fisheries and migratory bird habitats. Effective nutrient removal is essential to prevent algal blooms and maintain water quality in the bay, which is a vital ecological and economic resource for Zhejiang Province.
