Guangxi Wastewater Treatment Plant, Sanshan, Guangxi, China

The Guangxi wastewater treatment plant is located in Sanshan, Luchuan County, Yulin City, Guangxi Zhuang Autonomous Region, China. It serves a population of 200,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, more than 50 km from the coast, and its treated effluent likely discharges into local rivers that flow toward the South China Sea. China's wastewater treatment standards, such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment as a baseline, with more stringent nutrient removal in sensitive watersheds. For a plant serving 200,000 people, advanced treatment (e. g. , biological nutrient removal) is commonly expected to meet Class 1A or 1B standards, especially if the receiving water body is ecologically sensitive. Given its location in Guangxi, the treated wastewater likely enters the local river network, eventually draining into the Pearl River basin or coastal waters of the South China Sea. This region supports diverse aquatic ecosystems and is important for fisheries and agriculture, making effective treatment critical for downstream water quality.

The plant discharges into local rivers that are part of the broader Pearl River basin or directly into coastal waters of the South China Sea. This watershed supports diverse aquatic life and is used for irrigation and fisheries. Effective nutrient removal is important to prevent eutrophication in downstream estuaries and coastal zones, which are ecologically sensitive areas.
