Guangxi Wastewater Treatment Plant, Fusui County, Guangxi, China

The Guangxi wastewater treatment plant is located in Fusui County, Chongzuo City, Guangxi Zhuang Autonomous Region, China. It serves a population equivalent of approximately 55,000 people, placing it in the medium-sized agglomeration category. The facility is part of China's expanding wastewater infrastructure, which is governed by national discharge standards (GB 18918-2002) that mandate secondary treatment for urban plants. As a plant serving a medium-sized population, it is expected to provide at least secondary treatment to meet the Class 1-B or 1-A discharge standards under Chinese regulations. Typical facilities of this scale in Guangxi employ activated sludge processes with nutrient removal to protect downstream water quality. The plant discharges into local waterways that ultimately drain into the Zuo River, a tributary of the Pearl River system. The Pearl River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. The plant's operation helps reduce nutrient and pollutant loads entering this important river system.

The plant's treated effluent flows into the Zuo River, which joins the Yu River to form the Pearl River, one of China's major river systems. The Pearl River basin supports a rich diversity of fish species and provides critical habitat for migratory birds. Downstream, the river discharges into the South China Sea near Guangzhou, a region with extensive mangrove forests and estuarine ecosystems that are sensitive to nutrient pollution. Effective treatment at this plant helps protect these downstream environments from eutrophication and contamination.
