Overview
Zhejiang wastewater treatment plant serves Yuyao City, Zhejiang Province, China, with a population equivalent of 520,000. The plant has a designed capacity of 1.00 (unit unspecified) and operates under China's national wastewater discharge standards
The Zhejiang wastewater treatment plant is located in Yuyao City, Zhejiang Province, China, serving a population equivalent of 520,000. This facility is part of the municipal wastewater infrastructure for the region, which includes the town of Simen and the broader Ningbo metropolitan area. As a large-scale treatment plant, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving over 100,000 people. The plant's designed capacity is 1. And it likely employs biological treatment processes typical for facilities of this size. The treated effluent is discharged into local water bodies that eventually drain into the East China Sea via the Yong River system. The plant plays a critical role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated and industrialized Yangtze River Delta region.
Environmental context
The plant's discharge enters the local river network, which flows into the Yong River and ultimately reaches the East China Sea. This coastal region supports diverse marine life and is an important fishing ground. The plant's nutrient removal helps mitigate eutrophication risks in the receiving waters, which are subject to seasonal algal blooms due to agricultural and urban runoff.
