Guangdong Wastewater Treatment Plant, Lianping County, Guangdong Province

The Guangdong wastewater treatment plant is located in Lianping County, Heyuan City, Guangdong Province, China. It serves a population of approximately 32,000 people, classifying it as a medium-sized municipal facility in the region. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent limits for conventional pollutants and nutrients. Plants of this scale typically employ secondary biological treatment processes such as activated sludge or sequencing batch reactors to meet these standards. The plant discharges treated effluent into local waterways that ultimately drain into the Dong River system, a major tributary of the Pearl River Delta. The Pearl River Delta is a densely populated and economically vital region, and proper wastewater treatment is critical to protecting downstream water quality and aquatic ecosystems.

The plant's treated effluent flows into the Dong River basin, which is part of the larger Pearl River system. The Pearl River Delta supports diverse aquatic life and provides drinking water for millions. Effective nutrient removal at this plant helps prevent eutrophication in downstream reservoirs and coastal waters.
