Overview
Henan wastewater treatment plant serves Xingyang, Henan, China, with a population of 130,000. It operates under China's national wastewater standards for medium-sized agglomerations.
The Henan wastewater treatment plant is located in Xingyang, a city under the administration of Zhengzhou in Henan Province, China. Serving a population of approximately 130,000, the plant is part of the municipal wastewater infrastructure for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations of this scale are typically required to achieve secondary treatment with nutrient removal, especially in sensitive watersheds. The plant's operational context aligns with these regulatory expectations, ensuring treated effluent meets environmental standards. The treated wastewater from this facility ultimately drains into the Yellow River basin, a major waterway in northern China. The Yellow River supports extensive agricultural irrigation and provides drinking water for millions. Proper treatment is critical to prevent eutrophication and protect downstream aquatic ecosystems.
Environmental context
The plant discharges into the Yellow River basin, which flows through Henan Province and eventually reaches the Bohai Sea. The Yellow River is a vital water source for agriculture and urban supply in northern China, but it faces challenges from nutrient pollution and industrial runoff. Effective wastewater treatment helps mitigate these impacts, supporting the river's ecological health and biodiversity.
