Overview
Zhejiang wastewater treatment plant serves Linhai City, Zhejiang Province, China, with a population of 300,000. It has a designed capacity of 1.00 unit, operating under China's national wastewater standards.
The Zhejiang wastewater treatment plant is located in Linhai City, within Taizhou Prefecture, Zhejiang Province, China. It serves a population of approximately 300,000, classifying it as a large-scale municipal facility under China's urban wastewater management framework. The plant is part of the region's infrastructure to manage domestic and industrial wastewater from the urban area. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set effluent limits based on receiving water sensitivity. For large agglomerations like this, advanced treatment is often required to meet Grade 1A or 1B standards, especially when discharging into sensitive water bodies. The plant's designed capacity is reported as 1. Typical capacities for such populations range from 50,000 to 100,000 m³/day. The treated effluent likely discharges into a local river or waterway that flows into the East China Sea. Linhai is situated inland but within 50 km of the coast, meaning the plant's discharge can affect downstream aquatic ecosystems and coastal water quality. Proper treatment is critical to protect the region's water resources and support sustainable development.
Environmental context
The plant's discharge likely enters a tributary of the Ling River or another watercourse in the Taizhou region, which ultimately drains into the East China Sea. This coastal zone supports diverse marine life and is important for local fisheries. The watershed is influenced by monsoon climate, with seasonal variations in flow. Effective treatment helps prevent eutrophication and protects downstream habitats, including estuarine and coastal ecosystems that are sensitive to nutrient loading.
