Overview
Guangdong wastewater treatment plant serves 80,000 people in Zhongshan, Guangdong, China. The facility operates under China's national wastewater standards for urban agglomerations of this scale.
The Guangdong wastewater treatment plant is located in Zhongshan City, Guangdong Province, China, serving a population of approximately 80,000. The facility is situated in the Pearl River Delta region, a densely populated and economically vital area. As a medium-sized agglomeration, the plant plays a key role in managing municipal wastewater from the surrounding urban and industrial zones. The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For agglomerations serving around 80,000 people, secondary biological treatment with nutrient removal is typically required to meet Class 1A or 1B discharge limits, especially in sensitive watersheds. The designed capacity is reported as 1.00 (likely in 10,000 m³/d), indicating a facility sized for the served population. The plant discharges treated effluent into local waterways that ultimately drain into the Pearl River Estuary and the South China Sea. The Pearl River Delta is an ecologically sensitive region supporting diverse aquatic life and important fisheries. Proper wastewater treatment is critical to protect water quality in this densely populated and industrialized area.
Environmental context
The plant's treated effluent flows into the Pearl River system, which empties into the Pearl River Estuary and then the South China Sea. This watershed supports extensive aquaculture, mangrove habitats, and migratory bird populations. The region faces challenges from industrial pollution and urban runoff, making effective wastewater treatment essential for maintaining downstream water quality and ecosystem health.
