Overview
Guangxi wastewater treatment plant serves 140,000 people in Laibin, Guangxi, China. It operates under China's national wastewater discharge standards for urban treatment facilities.
The Guangxi wastewater treatment plant is located in Lingnan Town, Heshan City, part of Laibin City in Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 140,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. The plant is expected to meet Class 1A or 1B standards depending on the receiving water's sensitivity, ensuring effective removal of organic matter and nutrients. The plant's treated effluent likely discharges into a tributary of the Hongshui River, which flows into the Pearl River system and eventually reaches the South China Sea. This downstream connection underscores the plant's role in protecting the Pearl River basin's water quality and the coastal marine environment.
Environmental context
The plant's discharge enters the Hongshui River system, a major tributary of the Pearl River, which flows through Guangxi and Guangdong before emptying into the South China Sea near the Pearl River Delta. The Pearl River basin supports diverse aquatic life and is a critical water resource for millions of people. Effective treatment at this plant helps reduce nutrient and pollutant loads that could otherwise contribute to eutrophication in downstream reservoirs and coastal waters.
