Overview
Henan wastewater treatment plant serves Shangjie District, Zhengzhou, China, with a population of 131,500. It operates under China's national wastewater standards.
The Henan wastewater treatment plant is located in Shangjie District, Zhengzhou, Henan Province, China. It serves a population of approximately 131,500, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, away from coastal areas, and its operations are part of the municipal infrastructure for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to achieve secondary treatment with nutrient removal, especially in sensitive watersheds. The plant is expected to meet these regulatory requirements to protect local water quality. The treated effluent from the plant likely discharges into a tributary of the Yellow River basin, which ultimately flows into the Bohai Sea. The plant plays a crucial role in maintaining the ecological health of the local waterways and downstream environments, supporting aquatic life and preventing eutrophication in the region.
Environmental context
The plant discharges into the Yellow River basin, which flows through northern China and empties into the Bohai Sea. This watershed supports diverse aquatic ecosystems and is vital for agriculture and drinking water supply. The region faces challenges from industrial and agricultural runoff, making effective wastewater treatment essential for maintaining water quality and preventing algal blooms in downstream waters.
