Fujian Wastewater Treatment Plant, Longhai District, Fujian, China

The Fujian wastewater treatment plant is situated in Longhai District, Zhangzhou, Fujian Province, China. It serves a population of approximately 38,000 people, classifying it as a medium-sized agglomeration under typical Chinese municipal wastewater management frameworks. As a facility in China, the plant operates under national wastewater treatment standards, which mandate secondary treatment for urban wastewater. For agglomerations of this scale, Chinese regulations typically require compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits on key pollutants. It is expected to meet these national standards. The plant is located within 50 km of the coast, suggesting its treated effluent likely discharges into a river or estuary that flows into the Taiwan Strait or the South China Sea. This proximity to marine waters underscores the importance of effective treatment to protect coastal ecosystems. The plant contributes to safeguarding local water bodies and downstream marine environments from pollution.

The plant is situated in the coastal region of Fujian, within the Jiulong River basin, which drains into the Taiwan Strait. The Jiulong River is a major watercourse in southern Fujian, supporting diverse aquatic life and providing water for agriculture and industry. Downstream, the estuary and coastal waters are ecologically sensitive areas that host fisheries and migratory bird species. Effective wastewater treatment is crucial to prevent nutrient enrichment and contamination that could harm these marine ecosystems.
