Guangxi Wastewater Treatment Plant, Baise, Guangxi Zhuang Autonomous Region

The Guangxi wastewater treatment plant is located in Longlin Various Nationalities Autonomous County, Baise City, Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 42,000, placing it in the medium agglomeration category for Chinese wastewater infrastructure. As a facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For inland plants like this, secondary treatment with nutrient removal is typically required to protect downstream water quality. The plant discharges into local waterways that ultimately drain into the Pearl River basin, one of China's major river systems. The Pearl River flows through Guangxi and Guangdong before reaching the South China Sea, supporting diverse aquatic ecosystems and providing water for agriculture and urban use.

The plant's treated effluent enters local streams that feed into the Pearl River basin, which flows southeast through Guangxi and Guangdong provinces. The Pearl River estuary supports important fisheries and migratory bird habitats. As an inland facility, the plant's discharge affects freshwater ecosystems rather than coastal marine environments, making nutrient control critical for preventing eutrophication in downstream rivers and reservoirs.
