Overview
Henan wastewater treatment plant serves Wenfeng District, Anyang, Henan, China, with a population of 67,000. It operates under China's national wastewater standards.
The Henan wastewater treatment plant is located in Wenfeng District, Anyang, Henan Province, China. It serves a population of approximately 67,000 people, making it a medium-sized municipal facility in the region. As a Chinese wastewater treatment plant, it operates under the national discharge standards set by the Ministry of Ecology and Environment. For a facility of this scale, secondary treatment is typically required, with potential nutrient removal in sensitive watersheds. The plant discharges treated effluent into local waterways that ultimately drain into the Hai River basin, which flows into the Bohai Sea. The Hai River system supports agricultural irrigation and urban water supply, and its ecological health is important for downstream aquatic life and coastal water quality.
Environmental context
The plant's treated effluent enters the local drainage network within the Hai River basin, which flows eastward into the Bohai Sea. The Hai River system is heavily influenced by agricultural runoff and urban discharges, making wastewater treatment crucial for controlling nutrient loads and protecting downstream aquatic habitats. The Bohai Sea is a semi-enclosed water body with limited water exchange, so nutrient inputs can contribute to eutrophication and algal blooms.
Frequently asked questions
The plant is located in Wenfeng District, Anyang, Henan Province, China, at Guanghua Road, Guanghua Road Subdistrict.
The plant serves approximately 67,000 people in the Wenfeng District area.
The plant discharges treated effluent into local waterways that are part of the Hai River basin, which ultimately flows into the Bohai Sea.
The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban facilities. The Ministry of Ecology and Environment sets effluent limits for pollutants like COD, ammonia, and phosphorus.
For a medium-sized agglomeration of this scale, secondary biological treatment (such as activated sludge) is standard. In environmentally sensitive areas, additional nutrient removal may be required to meet stricter discharge limits.
