Guangdong Wastewater Treatment Plant, Qingyuan, Guangdong Province, China

The Guangdong wastewater treatment plant is located in Qingyuan City, Guangdong Province, China. It serves a population equivalent of 65,400, classifying it as a medium-sized agglomeration under Chinese wastewater regulations. The plant is situated inland, more than 50 km from the coast, and its treated effluent likely enters the Bei River system, a tributary of the Pearl River. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to meet secondary treatment standards, with some facilities in sensitive areas requiring tertiary treatment. It is expected to comply with local environmental protection bureau permits. The receiving water body is part of the Pearl River basin, one of China's largest and most ecologically significant river systems. The downstream environment supports diverse aquatic life and provides water for agriculture, industry, and domestic use. The plant plays a key role in protecting water quality in the region, particularly as Qingyuan is upstream of major urban centers like Guangzhou.

The plant discharges into the Bei River, a major tributary of the Pearl River, which flows through Guangdong Province and ultimately into the South China Sea. The Pearl River delta is a densely populated and economically vital region, with high ecological sensitivity due to its role in supporting fisheries, wetlands, and migratory bird habitats. The plant's operations help mitigate nutrient and pollutant loads that could otherwise contribute to eutrophication and degradation of downstream water quality.
