Overview
Guangxi wastewater treatment plant serves Xing'an County, Guangxi, China, with a population equivalent of 123,000. It operates under China's national wastewater discharge standards.
The Guangxi wastewater treatment plant is located in Xing'an County, Guilin City, Guangxi Zhuang Autonomous Region, China. It serves a population equivalent of 123,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. As a plant of this scale in China, it is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Typical facilities of this size employ activated sludge processes with biological nutrient removal. The plant discharges treated effluent into local water bodies within the Xiang River basin, which flows into Dongting Lake and ultimately the Yangtze River. This downstream chain supports extensive aquatic ecosystems and provides water for agricultural and urban use in southern China.
Environmental context
The plant's treated effluent enters the Xiang River system, a tributary of Dongting Lake, which connects to the Yangtze River. This watershed supports diverse aquatic life and is ecologically sensitive due to its role in flood regulation and biodiversity. The region's subtropical climate and agricultural activity necessitate effective nutrient removal to prevent eutrophication in downstream lakes.
