Hainan Wastewater Treatment Plant, Dongfang City, Hainan Province

The Hainan wastewater treatment plant is located in Basuo Town, Dongfang City, Hainan Province, China. It serves a population of approximately 165,800, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant's coastal proximity places it within a sensitive environmental zone where treated effluent discharge is regulated to protect marine ecosystems. The plant operates under China's national wastewater discharge standards, which require secondary treatment as a baseline for urban plants. For facilities near coastal waters, enhanced nutrient removal may be mandated to prevent eutrophication. The designed capacity of 1.00 unit suggests a moderate scale, though operational data is limited. The plant's receiving water body is likely a river or direct coastal outfall flowing into the South China Sea. This region supports diverse marine life and is important for local fisheries. Effective treatment is critical to minimize pollution impacts on coastal water quality and downstream ecosystems.

The plant discharges into a water body that ultimately drains into the South China Sea, a semi-enclosed sea with significant biodiversity and economic importance. The coastal waters near Dongfang City support fisheries and marine habitats that are sensitive to nutrient loading and contaminants. Proper treatment is essential to protect these ecosystems from eutrophication and toxic pollutants.
