Overview
Hainan wastewater treatment plant serves Wanning in Hainan Province, China, with a designed capacity of 1.00 and a population served of 59,000. The plant operates under China's national wastewater regulations.
The Hainan wastewater treatment plant is located in Wanning, a city on the eastern coast of Hainan Province, China. It serves a population of approximately 59,000 people, making it a medium-sized agglomeration. In China, wastewater treatment plants are regulated under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For plants serving populations of this scale, secondary treatment with nutrient removal is typically required, especially in environmentally sensitive areas. The plant's location within 50 km of the coast suggests it may be subject to additional coastal discharge regulations. The treated effluent likely discharges into local water bodies that flow toward the South China Sea. Hainan Island is known for its tropical climate and diverse ecosystems, including coral reefs and mangroves along its coastline. Proper wastewater treatment is crucial to protect these sensitive marine environments from nutrient pollution and other contaminants.
Environmental context
The plant is located in Hainan Province, an island region with a tropical climate and extensive coastline along the South China Sea. The receiving water bodies are likely small rivers or streams that drain into the sea, supporting coastal ecosystems such as mangroves and coral reefs. These habitats are sensitive to nutrient loading and require effective wastewater treatment to maintain water quality and biodiversity.
Frequently asked questions
The Hainan wastewater treatment plant is located in Wanning, a city on the eastern coast of Hainan Province, China. Its coordinates are approximately 18.828 N, 110.410 E.
The plant serves a population of approximately 59,000 people, classifying it as a medium-sized agglomeration under typical wastewater management frameworks.
The treated wastewater is likely discharged into local rivers or streams that flow into the South China Sea. The plant's proximity to the coast (within 50 km) suggests that effluent may be subject to coastal discharge regulations to protect marine ecosystems.
The plant operates under China's national wastewater standards, primarily the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This standard sets limits on pollutants such as COD, BOD, and nutrients, and may require advanced treatment for plants in sensitive coastal areas.
For a medium-sized agglomeration in China, secondary treatment with nutrient removal is typically required. In coastal or environmentally sensitive regions, tertiary treatment may be mandated to reduce nitrogen and phosphorus loads to protect marine ecosystems.
