Henan Wastewater Treatment Plant, Hualong District, Puyang, Henan Province

The Henan wastewater treatment plant is located in Hualong District, Puyang City, Henan Province, China. It serves a population of approximately 140,000, placing it in the medium-to-large agglomeration category. The plant is situated inland, away from coastal areas, and its operations are part of the municipal infrastructure for the region. Under China's wastewater regulatory framework, plants serving this population size are typically required to meet secondary treatment standards as a minimum, with potential for advanced treatment depending on local environmental sensitivity. The plant's design and operational details are managed by local authorities to ensure compliance with national discharge standards. The treated effluent is discharged into local waterways that eventually drain into the Yellow River basin, a major river system in northern China. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's rivers and agricultural areas.

The plant discharges into local waterways that are part of the Yellow River basin, one of China's most important river systems. The Yellow River flows through arid and semi-arid regions, making water quality management critical for agricultural irrigation, drinking water supply, and ecosystem health. Downstream areas include wetlands and riverine habitats that support diverse aquatic life and migratory birds.
