Zhejiang Wastewater Treatment Plant, Putuo District, Zhoushan | China

The Zhejiang wastewater treatment plant is located in Putuo District, Zhoushan City, Zhejiang Province, China, serving a population of 72,000. The facility is part of the municipal wastewater infrastructure for the Zhoushan archipelago region, an important urban and industrial area on China's eastern coast. With a designed capacity of 1.00 (likely in cubic meters per day or similar unit), the plant operates under China's national wastewater discharge standards, which are enforced by local environmental protection bureaus. For agglomerations of this scale, secondary treatment is typically required, and the plant's treatment process aligns with national regulations aimed at reducing pollutants before discharge. The treated effluent from the plant is discharged into the East China Sea via local waterways. The receiving environment supports diverse marine life and is an important fishing ground. The plant plays a key role in protecting coastal water quality and mitigating eutrophication risks in the region.

The plant discharges into the East China Sea, a marginal sea of the Pacific Ocean that supports rich biodiversity and important fisheries. The Zhoushan archipelago area is ecologically sensitive due to its coastal wetlands and marine habitats. Proper wastewater treatment is critical to prevent nutrient loading and harmful algal blooms that can affect both local ecosystems and downstream coastal zones.
