Guangdong Wastewater Treatment Plant, Longhua District, Shenzhen

The Guangdong wastewater treatment plant is located in Longhua District, Shenzhen, within Guangdong Province, China. It serves a population equivalent of 480,000, classifying it as a large agglomeration under Chinese wastewater management standards. The facility is situated in an urban area of Shenzhen, a major economic hub in southern China. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater treatment plants serving populations over 100,000. The designed capacity is recorded as 1.00, though the unit is unspecified. As a large-scale facility, it is expected to comply with stringent effluent limits to protect receiving water bodies. The plant discharges treated wastewater into local waterways that ultimately drain into the Pearl River Delta and the South China Sea. The Pearl River Delta is a densely populated and ecologically sensitive region, supporting diverse aquatic life and providing water resources for agriculture and industry. Proper treatment is critical to prevent eutrophication and protect downstream ecosystems.

The plant's treated effluent flows into the local drainage network within the Pearl River Basin, eventually reaching the Pearl River Estuary and the South China Sea. The Pearl River Delta is a vital ecological and economic zone, supporting mangrove forests, fish nurseries, and migratory bird habitats. Nutrient and pollutant loads from urban wastewater must be carefully managed to avoid algal blooms and hypoxia in coastal waters.
