Overview
Henan wastewater treatment plant serves Changyuan City in Henan Province, China, with a population of 132,000. The plant operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Pudong Street, Changyuan City, Xinxiang, Henan Province, China. It serves a population of approximately 132,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The facility is situated inland, away from coastal areas, and its operations are subject to China's national discharge standards (GB 18918-2002) which mandate pollutant removal for municipal wastewater. As a plant serving over 100,000 people, it falls under China's Class I or II discharge criteria depending on the receiving water's sensitivity. Chinese regulations typically require secondary biological treatment with nutrient removal for plants of this scale. The population served suggests a substantial treatment capacity. The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin, a major river system in northern China. The Yellow River supports extensive agricultural irrigation and provides water for millions of people downstream. Proper treatment is critical to prevent eutrophication and protect water quality in this ecologically and economically vital basin.
Environmental context
The plant's treated effluent flows into local tributaries of the Yellow River, which is the second-longest river in China and a crucial water source for agriculture, industry, and domestic use in the North China Plain. The Yellow River basin supports diverse aquatic life and migratory birds, but faces challenges from industrial pollution and agricultural runoff. Effective wastewater treatment helps reduce nutrient loading and protect downstream ecosystems, including the Yellow River Delta, an important wetland area.
