Overview
Guangxi wastewater treatment plant serves Changzhou District, Wuzhou, Guangxi, China, with a population equivalent of 300,000. It operates under China's national wastewater discharge standards.
The Guangxi wastewater treatment plant is located in Changzhou District, Wuzhou City, Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 300,000, classifying it as a large-scale municipal facility within the region's urban wastewater infrastructure. As a major treatment plant in Guangxi, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this size. The plant likely employs conventional activated sludge or similar biological processes to meet these standards. The plant discharges treated effluent into local water bodies that ultimately drain into the Xi River system, a major tributary of the Pearl River. The Pearl River Delta downstream is an ecologically and economically vital region, supporting diverse aquatic life and intensive agriculture. Proper treatment at this plant helps protect water quality in the Xi River and downstream ecosystems.
Environmental context
The plant's treated effluent flows into the Xi River, a major tributary of the Pearl River system, which drains into the South China Sea. The Pearl River basin supports a rich diversity of fish species and is an important migratory corridor for aquatic life. Downstream, the Pearl River Delta is a densely populated and industrialized region where water quality management is critical for both ecological health and human use.
