Overview
Zhejiang wastewater treatment plant serves Cixi, Zhejiang, China, with a designed capacity of 1.00 and a population equivalent of 28,000. It operates under China's national wastewater discharge standards.
The Zhejiang wastewater treatment plant is located in Cixi, a city in Zhejiang Province, China. It serves a population equivalent of 28,000, placing it in the small-to-medium agglomeration category. The plant is situated in the rapidly urbanizing Yangtze River Delta region, where industrial and municipal wastewater management is critical for environmental protection. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. As part of China's 14th Five-Year Plan, wastewater infrastructure in Zhejiang has been upgraded to meet stricter effluent limits. The treated effluent is discharged into local waterways that ultimately drain into the East China Sea. The region's dense river network and coastal location make proper treatment essential to prevent eutrophication and protect marine ecosystems. The plant contributes to the health of the Qiantang River basin and Hangzhou Bay, a semi-enclosed coastal water body.
Environmental context
The plant's receiving water body is part of the Qiantang River system, which flows into Hangzhou Bay and then the East China Sea. This coastal zone supports diverse marine life and is an important fishing ground. Nutrient loading from untreated wastewater could exacerbate algal blooms and hypoxia in the bay, making tertiary-level treatment beneficial for downstream water quality.
