Guangxi Wastewater Treatment Plant, Luzhai County, Guangxi, China

The Guangxi wastewater treatment plant is located in Luzhai County, Liuzhou City, Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 120,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, away from coastal areas, and its operations are integral to local water quality management. The plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants serving populations of this scale, secondary biological treatment with nutrient removal is typical, often followed by disinfection. The regulatory framework also includes requirements for sludge treatment and disposal. The treated effluent is discharged into local water bodies that eventually drain into the Pearl River system, which flows into the South China Sea. The plant plays a critical role in protecting downstream aquatic ecosystems, including rivers and estuaries that support diverse aquatic life and are important for regional biodiversity and fisheries.

The plant discharges into local waterways that are part of the Pearl River basin, eventually reaching the South China Sea. This watershed supports diverse aquatic habitats and is ecologically sensitive due to its role in regional fisheries and biodiversity. The plant's operations help mitigate nutrient and pollutant loads that could otherwise impact downstream water quality and marine ecosystems.
