Overview
Guangxi wastewater treatment plant serves Longzhou County, Guangxi, China, with a population of 41,900. It operates under China's national wastewater standards for municipal facilities.
The Guangxi wastewater treatment plant is located in Longzhou County, Chongzuo City, Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 41,900, classifying it as a medium-sized municipal facility in the region. As a Chinese wastewater treatment plant, it operates under the national discharge standards set by the Ministry of Ecology and Environment. For facilities serving populations between 10,000 and 100,000, secondary treatment is typically required, with potential nutrient removal in sensitive areas. It is expected to meet Class 1A or 1B standards under the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The plant discharges treated effluent into local water bodies that eventually drain into the Zuo River, a tributary of the Pearl River system. This river network flows southward through Guangxi and into the South China Sea near Guangzhou. The plant plays a key role in protecting the Zuo River and downstream ecosystems from untreated sewage, supporting water quality in a region known for karst landscapes and agricultural activity.
Environmental context
The plant's treated effluent likely enters local streams that feed into the Zuo River, which flows into the Pearl River system and ultimately the South China Sea. The Zuo River supports diverse aquatic life and is important for irrigation and drinking water in the region. Protecting this watershed from nutrient pollution and pathogens is critical for maintaining ecological balance in the karst terrain and downstream coastal waters.
