Guangdong Wastewater Treatment Plant, Longgang District, Shenzhen, China

The Guangdong wastewater treatment plant is located in Longgang District, Shenzhen, within Guangdong Province, China. It serves a population of approximately 30,000, classifying it as a small to medium-scale municipal facility. The plant is situated in the urbanized area of Shenzhen, a major economic hub in southern China. With a designed capacity of 1.00 (likely in cubic meters per day or similar unit), the plant is part of China's extensive wastewater infrastructure. China's wastewater treatment standards, such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set effluent limits based on the receiving water body's sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required to protect downstream water quality. The plant discharges into local waterways that ultimately flow into the South China Sea via the Pearl River Delta. The delta is a densely populated and ecologically significant region, supporting diverse aquatic life and serving as a critical migratory corridor for fish and birds. Proper treatment helps mitigate eutrophication and pollution in this sensitive coastal environment.

The plant's treated effluent enters the local drainage network within the Pearl River Delta, which discharges into the South China Sea. This coastal region supports important fisheries and marine biodiversity. Effective nutrient removal is critical to prevent algal blooms and hypoxia in the delta's estuaries, which are vital for local ecosystems and livelihoods.
