Overview
The Guangxi wastewater treatment plant serves Nandan County, Hechi, Guangxi, China, with a population equivalent of 120,000. It operates under China's national wastewater discharge standards.
The Guangxi wastewater treatment plant is located in Nandan County, Hechi City, Guangxi Zhuang Autonomous Region, China. It serves a population equivalent of 120,000, placing it in the medium-to-large agglomeration category. The plant is situated inland, approximately 50 km from the coast, and its treated effluent likely discharges into local rivers that flow toward the South China Sea. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which requires secondary treatment as a minimum and may necessitate advanced treatment for sensitive receiving waters. Typical facilities of this scale in Guangxi employ activated sludge processes with nutrient removal. The region is part of the Pearl River basin, with rivers draining into the South China Sea. The plant plays a key role in protecting local water quality and downstream ecosystems, including estuarine habitats that support diverse aquatic life and fisheries.
Environmental context
The plant is located in the mountainous region of northern Guangxi, within the broader Pearl River basin. Treated wastewater likely discharges into tributaries of the Hongshui River, which flows into the Pearl River Delta and ultimately the South China Sea. The downstream environment includes ecologically sensitive estuarine zones that support migratory fish and shellfish populations. Protecting water quality in this watershed is critical for maintaining biodiversity and supporting local communities that rely on fishing and agriculture.
