Guangxi Wastewater Treatment Plant, Tiandong County, Guangxi, China

The Guangxi wastewater treatment plant is located in Tiandong County, Baise City, Guangxi Zhuang Autonomous Region, China. Serving a population of 120,000, it is a medium-to-large agglomeration facility that plays a key role in managing municipal wastewater in the region. The plant is situated inland, away from the coast, and its operations are part of China's broader efforts to improve water quality under the Water Pollution Prevention and Control Action Plan. As a facility serving over 100,000 people, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard sets limits on key pollutants such as COD, BOD, ammonia nitrogen, and total phosphorus. The plant's design and operational parameters align with national requirements for protecting receiving water bodies, though specific treatment process details are not disclosed in available data. The treated effluent from the plant is discharged into local waterways that eventually drain into the Pearl River basin, a major river system in southern China. The Pearl River basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water for millions of people. Proper treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream water quality and ecological health.

The plant discharges into local streams that flow into the Pearl River basin, one of China's largest river systems. The Pearl River ultimately empties into the South China Sea, supporting critical estuarine and marine habitats. The region's subtropical climate and intensive agriculture make nutrient management particularly important to prevent eutrophication in downstream waters. The plant's treatment helps safeguard aquatic biodiversity and water quality for communities relying on the river system.
