Overview
Jiangsu wastewater treatment plant serves Xiangcheng District, Suzhou, China, with a designed capacity of 1.00 and population served of 31,000. It operates under China's national wastewater standards.
The Jiangsu wastewater treatment plant is located in Weixi Village, Weitang Town, Xiangcheng District, Suzhou, Jiangsu Province, China. It serves a population of approximately 31,000 people and has a designed capacity of 1.00 (likely in million cubic meters per day or similar unit). The plant is part of the municipal wastewater infrastructure for the Suzhou metropolitan area. As a facility in China, the plant operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For a plant serving a population of 31,000, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds like the Yangtze River Delta. The plant's treated effluent likely discharges into local waterways that ultimately flow into the Yangtze River or its tributaries, contributing to the Yangtze River Basin. The downstream environment includes Lake Taihu, a large freshwater lake that is ecologically and economically significant, supporting fisheries, agriculture, and drinking water supplies. Proper treatment is crucial to prevent eutrophication and protect aquatic biodiversity.
Environmental context
The plant is situated in the Yangtze River Delta, a densely populated and industrialized region. Treated wastewater likely enters local canals or rivers that drain into the Yangtze River, which flows into the East China Sea. The downstream Lake Taihu is a critical freshwater resource but has suffered from algal blooms due to nutrient pollution. The plant's operations help mitigate nutrient loading to this sensitive watershed.
