Henan Wastewater Treatment Plant, 曹乡固村, 延津县, Henan Province, China

The Henan wastewater treatment plant is located in 曹乡固村, 延津县, 新乡市, 河南省, China, serving a population of approximately 42,800. The facility is part of the municipal wastewater infrastructure for the region, which falls under China's national environmental regulations. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard sets limits for key pollutants such as COD, BOD, and ammonia nitrogen to protect receiving water bodies. The plant's treated effluent likely discharges into local waterways that eventually flow into the Yellow River basin, a major river system in northern China. The Yellow River supports extensive agricultural irrigation and provides drinking water for millions, making effective wastewater treatment critical for downstream water quality and ecosystem health.

The plant is situated inland in Henan province, within the Yellow River basin. Treated wastewater likely enters tributaries that flow into the Yellow River, which ultimately reaches the Bohai Sea. The Yellow River is a vital water source for agriculture and urban supply, and its lower reaches are ecologically sensitive due to high sediment loads and seasonal flow variations. Proper treatment helps reduce nutrient and pollutant loads that could otherwise contribute to eutrophication and degradation of aquatic habitats.
