Fujian Wastewater Treatment Plant, Longyan, Fujian Province, China

The Fujian wastewater treatment plant is located in Tieshan Street, Xinluo District, Longyan City, Fujian Province, China. It serves a population of 560,000, classifying it as a large-scale municipal facility under Chinese regulatory frameworks. The plant is situated inland, approximately 50 km from the coast, and its operations are critical for managing urban wastewater in the region. As a large agglomeration serving over 500,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. The plant's scale implies advanced treatment infrastructure to comply with national standards. The plant discharges treated wastewater into local waterways that ultimately drain into the Jiulong River basin, which flows into the Taiwan Strait. The receiving environment supports diverse aquatic life and is important for regional water quality. Effective treatment at this facility helps protect downstream ecosystems and supports sustainable water use in Fujian's rapidly urbanizing landscape.

The plant's treated effluent enters the Jiulong River system, which flows through Fujian Province and discharges into the Taiwan Strait. This watershed supports important fisheries and provides water for agriculture and industry. The downstream environment is ecologically sensitive, with seasonal variations in flow affecting dilution capacity. Proper nutrient removal is critical to prevent eutrophication in the coastal zone.
