Overview
The Zhejiang wastewater treatment plant serves Ninghai County in Zhejiang, China, with a designed capacity of 1.00 and a population served of 26,700. It operates under China's national wastewater regulations.
The Zhejiang wastewater treatment plant is located in Ninghai County, part of Ningbo City in Zhejiang Province, China. It serves a population of 26,700 and has a designed capacity of 1.00, indicating it is a medium-scale facility for the region. China's wastewater treatment standards are governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, especially in environmentally sensitive areas. The plant's treated effluent likely discharges into local waterways that flow into the East China Sea, as the facility is within 50 km of the coast. This proximity to marine waters necessitates careful management of nutrients and pollutants to protect coastal ecosystems and support regional water quality goals.
Environmental context
The plant's receiving waters are part of the Fenghua River system, which drains into Hangzhou Bay and ultimately the East China Sea. This coastal region supports diverse marine life and is an important area for fisheries and aquaculture. The plant's discharge must comply with stringent limits to prevent eutrophication and protect the ecological health of the bay and adjacent coastal waters.
