Overview
Fujian wastewater treatment plant serves Longhai District, Zhangzhou, Fujian, China, with a designed capacity of 1.00 and a population of 83,000. It operates under China's national wastewater standards.
The Fujian wastewater treatment plant is located in Longhai District, Zhangzhou, Fujian Province, China, along the Shenhai Expressway. It serves an estimated population of 83,000 people, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants serving populations of this scale, secondary biological treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant discharges into local waterways that ultimately drain into the Taiwan Strait via the Jiulong River system. The downstream environment supports estuarine and coastal ecosystems, including fisheries and migratory bird habitats. Effective nutrient removal is critical to prevent eutrophication in the receiving coastal waters.
Environmental context
The plant's treated effluent flows into the Jiulong River basin, which empties into the Taiwan Strait near Xiamen. This coastal region supports diverse marine life, including spawning grounds for commercial fish species. Nutrient loading from upstream sources can contribute to algal blooms in the strait, making advanced treatment important for protecting water quality and aquatic biodiversity.
