Fujian Wastewater Treatment Plant, Nan'an City, Fujian Province, China

The Fujian wastewater treatment plant is located in Xiangshan, Xiaxi Village, Nan'an City, Quanzhou City, Fujian Province, China. It serves a population of 136,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a facility in China, the plant operates under the national discharge standards set by the Ministry of Ecology and Environment, which mandate secondary treatment for urban wastewater. For agglomerations of this size, compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) is required, which includes limits on COD, BOD, ammonia nitrogen, and total phosphorus. The plant discharges treated effluent into local water bodies that eventually drain into the East China Sea via the Jin River or other coastal watersheds in Fujian Province. The region's aquatic ecosystems, including estuaries and coastal zones, benefit from proper wastewater treatment, which helps reduce nutrient loading and protect biodiversity.

The plant is located in Fujian Province, within the watershed of the Jin River or nearby coastal streams that flow into the Taiwan Strait and the East China Sea. This coastal region supports diverse marine life and important fisheries. Effective wastewater treatment is crucial to prevent eutrophication and maintain water quality in downstream estuaries and coastal habitats.
