Zhejiang Wastewater Treatment Plant, Pinghu, Zhejiang, China

The Zhejiang wastewater treatment plant is located in Pinghu City, Zhejiang Province, China, serving a population of approximately 83,000. It is situated in the Dushangang town area along Haihe Road, within the broader Jiaxing region. The plant's designed capacity is 1.00, indicating its scale in managing municipal wastewater. As a facility in China, the plant operates under national wastewater discharge standards, which require secondary treatment for urban wastewater. For agglomerations of this size, Chinese regulations mandate compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits on key pollutants. The plant's proximity to the coast suggests that treated effluent may be discharged into coastal waters, subject to stricter standards for marine protection. Given its coastal location within 50 km of the East China Sea, the treated wastewater likely drains into the sea via local rivers or directly. This area supports diverse aquatic life and is part of the broader Yangtze River Delta ecosystem, which is ecologically sensitive due to high population density and industrial activity. The plant plays a crucial role in protecting downstream water quality and marine habitats.

The plant is located within 50 km of the East China Sea, a major marginal sea of the Pacific Ocean. Treated wastewater likely discharges into local rivers that flow into Hangzhou Bay or directly into the sea. The coastal waters support fisheries and migratory bird populations, making nutrient and pollutant control critical. The region's dense urban and industrial development increases the risk of eutrophication and habitat degradation, emphasizing the need for effective treatment.
