Overview
The Guangdong wastewater treatment plant in Zhongshan City serves 150,000 people. It operates under China's national wastewater standards, discharging treated effluent into local waterways that drain to the Pearl River Delta.
The Guangdong wastewater treatment plant is located in Zhongshan City, Guangdong Province, China, serving a population of 150,000. The plant is part of the municipal infrastructure for the Zhongshan urban area, situated in the Pearl River Delta region. As a facility serving a medium-to-large agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. The designed capacity is 1. The plant discharges treated wastewater into local rivers or canals that ultimately flow into the Pearl River Delta and then the South China Sea. The Pearl River Delta is a densely populated and economically vital region, and the plant plays a key role in protecting downstream water quality and aquatic ecosystems from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Pearl River Delta watershed, which drains into the South China Sea. The delta is a highly productive estuarine environment supporting diverse aquatic life, including fisheries and migratory species. Nutrient loading from urban wastewater can contribute to eutrophication in coastal waters, making effective treatment critical for maintaining ecological balance.
