Overview
Zhejiang wastewater treatment plant serves Dinghai District, Zhoushan, China, with a population of 270,000. Located near the coast, it operates under China's national wastewater standards.
The Zhejiang wastewater treatment plant is located in Dinghai District, Zhoushan City, Zhejiang Province, China. It serves a population of approximately 270,000, classifying it as a large-scale municipal facility within the region. The plant is situated near the coast, which influences its discharge requirements and environmental considerations. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater. For facilities serving over 100,000 people, stricter nutrient removal may be required in sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a substantial infrastructure investment. The plant's treated effluent likely discharges into the East China Sea via local waterways. The surrounding watershed includes the Zhoushan archipelago, a coastal region with significant marine biodiversity. Proper treatment is critical to protect coastal ecosystems, including fisheries and aquaculture that are vital to the local economy.
Environmental context
The plant is located within 50 km of the coast, with discharge likely entering the East China Sea via small rivers or direct outfall. The East China Sea supports diverse marine life, including fish stocks and migratory species. The region's coastal waters are ecologically sensitive, requiring effective nutrient removal to prevent eutrophication and algal blooms.
