Overview
Henan wastewater treatment plant serves Dengzhou City in Henan Province, China, with a population equivalent of 185,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Dengzhou City, Henan Province, China, serving a population of approximately 185,000. Situated in the Tuohe Street area, the plant is part of the municipal infrastructure for the city of Dengzhou, which lies in the southern part of Henan Province. The facility plays a key role in managing wastewater from this medium-sized urban agglomeration. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater treatment plants serving populations over 100,000. China's Water Pollution Prevention and Control Action Plan requires such facilities to meet Class 1A or 1B discharge standards, depending on the receiving water body's sensitivity. The plant's capacity is designed to handle the wastewater from its service area, with treatment processes typically including biological treatment and disinfection. The treated effluent is discharged into local water bodies that ultimately drain into the Yangtze River basin via the Han River system. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the region, which is part of the larger Yangtze River watershed. Proper wastewater treatment is critical for maintaining the ecological health of rivers and lakes in Henan Province.
Environmental context
The plant's treated effluent flows into local waterways that are part of the Han River system, a major tributary of the Yangtze River. The Han River supports diverse aquatic life and provides water for agriculture and industry in the region. Downstream, the Yangtze River is ecologically sensitive, hosting numerous fish species and providing habitat for migratory birds. Effective wastewater treatment is essential to prevent eutrophication and protect water quality in this important watershed.
