And it plays a key role in treating municipal wastewater from the urban area. As a facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For plants serving over 100,000 people, secondary treatment with nutrient removal is typically required, especially if discharging into sensitive waters. The plant's treated effluent likely discharges into a local river or waterway that eventually flows into the South China Sea, given Hainan's island geography. The surrounding watershed supports diverse aquatic life and is important for regional water resources. Proper treatment helps protect downstream ecosystems and coastal water quality.
