Guangdong Wastewater Treatment Plant, Nanshan District, Shenzhen

The Guangdong wastewater treatment plant is located in Nanshan District, Shenzhen, Guangdong Province, China. It serves a population of approximately 65,000 residents in the urban area. The facility is situated within 50 km of the coast, indicating its role in protecting coastal waters. As a municipal wastewater treatment plant in China, it operates under national standards that typically require secondary treatment for agglomerations of this size. The designed capacity is 1. Chinese regulations for wastewater treatment are governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. The plant discharges into the local water system, which ultimately drains into the South China Sea. The receiving water body supports diverse aquatic life and is part of the Pearl River Delta ecosystem, a region of high ecological and economic importance. Proper treatment helps mitigate nutrient loading and protect downstream marine environments.

The plant is located in the Pearl River Delta, a densely populated and industrialized region that drains into the South China Sea. The delta supports extensive mangrove forests, estuarine habitats, and fisheries. Treated effluent from the plant contributes to the overall water quality of the delta, which is critical for both ecological health and human use. The proximity to the coast (within 50 km) means that nutrient and pollutant discharges can directly affect coastal marine ecosystems.
