Fujian Wastewater Treatment Plant, Fuding, Fujian Province, China

The Fujian wastewater treatment plant is located in Fuding City, within Ningde Prefecture, Fujian Province, China. It serves a population of approximately 260,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. Under China's national wastewater discharge standards, large-scale plants like this are expected to meet stringent effluent limits, often requiring advanced treatment processes to protect receiving waters. The regulatory framework includes the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for COD, BOD, ammonia nitrogen, and total phosphorus. Plants serving over 200,000 people typically need tertiary treatment to comply with Class 1A or 1B standards, especially in environmentally sensitive coastal areas. The plant's proximity to the coast (within 50 km) means its treated effluent likely discharges into a river or directly into the East China Sea. The region's watershed drains from the Wuyi Mountains eastward, with rivers such as the Ao Jiang and Jiao Xi flowing through Fuding. The coastal waters support diverse marine life, including fisheries and aquaculture, making proper treatment essential to prevent eutrophication and protect ecosystem health.

The plant is situated in the coastal watershed of Fujian Province, with treated effluent likely entering the East China Sea via local rivers such as the Ao Jiang or Jiao Xi. The downstream environment includes estuarine and marine habitats that support commercial fisheries and migratory bird populations. Nutrient loading from untreated or inadequately treated wastewater could contribute to algal blooms and hypoxia in coastal waters, emphasizing the need for effective nutrient removal.
