Overview
Guangdong wastewater treatment plant serves Yunan County in Guangdong, China, with a population of 58,100. It operates under China's national wastewater regulations for medium-sized agglomerations.
The Guangdong wastewater treatment plant is located in Yunan County, Yunfu City, Guangdong Province, China. It serves a population of approximately 58,100, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant is situated inland, away from coastal areas, and its operations are part of the regional water infrastructure for the Pearl River basin. As a facility serving a medium-sized population, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This national regulation sets effluent limits for biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients, with stricter requirements for plants discharging into sensitive water bodies. Typical facilities of this scale employ activated sludge or similar biological treatment methods. The plant discharges treated wastewater into a local waterway that ultimately flows into the Pearl River system, one of China's major river basins. The Pearl River Delta is a densely populated and ecologically important region, supporting diverse aquatic life and providing water resources for agriculture and industry. The plant's operation helps protect downstream water quality and reduce pollution loads to the South China Sea.
Environmental context
The plant discharges into a tributary of the Pearl River system, which flows through Guangdong Province and empties into the South China Sea via the Pearl River Delta. The delta is a critical ecological zone, supporting mangrove forests, estuarine fisheries, and migratory bird populations. The plant's treatment helps mitigate nutrient and pollutant loads that could otherwise contribute to eutrophication and habitat degradation in downstream waters.
