Overview
Hainan wastewater treatment plant serves 130,000 people in Jiyang District, Sanya, Hainan, China. It operates under China's national wastewater standards, discharging treated effluent into the South China Sea.
The Hainan wastewater treatment plant is located in Hongsha, Jiyang District, Sanya, Hainan Province, China. It serves a population of approximately 130,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating its scale in the region. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater plants serving populations over 100,000. The facility is situated within 50 km of the coast, suggesting its effluent may be discharged into the South China Sea, requiring compliance with marine discharge regulations. The plant's receiving water body is the South China Sea, a major marine ecosystem supporting diverse aquatic life and important fisheries. The treated effluent contributes to the nutrient load in coastal waters, necessitating effective treatment to minimize environmental impact. The plant plays a key role in protecting the coastal environment of Hainan Island, a region known for its tourism and ecological significance.
Environmental context
The Hainan plant discharges into the South China Sea, a semi-enclosed sea that supports coral reefs, mangroves, and migratory species. The coastal waters near Sanya are ecologically sensitive, hosting diverse marine habitats. Proper wastewater treatment is critical to prevent eutrophication and protect the region's biodiversity and tourism-dependent economy.
