Overview
Chongqing wastewater treatment plant serves Zhongxian County in Chongqing, China, with a population equivalent of 165,000. The plant has a designed capacity of 1.00 (units unspecified) and is located within 50 km of the coast.
The Chongqing wastewater treatment plant is located in Zhongxian County, Chongqing, China, serving a population equivalent of 165,000. The plant's designed capacity is 1.00 (units unspecified), and it operates as part of the municipal wastewater infrastructure for the region. As a large agglomeration serving over 150,000 people, the plant is expected to meet secondary treatment standards under China's national wastewater discharge regulations. Typical facilities of this scale in China employ biological treatment processes such as activated sludge. The plant discharges treated wastewater into the Yangtze River basin, which flows through Chongqing and eventually reaches the East China Sea. The Yangtze River is a critical water resource for millions of people and supports diverse aquatic ecosystems. Proper treatment is essential to protect downstream water quality and ecological health.
Environmental context
The plant is located in the Yangtze River basin, which drains into the East China Sea. The Yangtze River is one of the world's major rivers, supporting a rich diversity of fish and other aquatic life. The plant's discharge contributes to the river's flow, and effective treatment is crucial to prevent nutrient pollution and protect downstream ecosystems, including important fisheries and migratory species.
Frequently asked questions
The plant is located in Zhongxian County, Chongqing, China, near the Yuxi Bridge.
The plant serves a population equivalent of 165,000 people.
The plant has a designed capacity of 1.00 (units unspecified).
China's wastewater discharge standards require secondary treatment for large agglomerations. Plants serving over 150,000 people must meet stringent effluent limits to protect water bodies like the Yangtze River.
Typical treatment for this scale includes primary sedimentation followed by biological treatment such as activated sludge or sequencing batch reactors, often with nutrient removal to meet discharge standards.
