Overview
The Hebei wastewater treatment plant serves Anping County in Hengshui City, Hebei Province, China. It treats wastewater for approximately 84,600 residents as part of the region's municipal infrastructure.
The Hebei wastewater treatment plant is located in Xi Liangwa Township, Anping County, within Hengshui City, Hebei Province, China. Serving a population of approximately 84,600, the plant is a key component of the local wastewater management system for this inland urban area. As a municipal facility in China, the plant operates under national wastewater discharge standards, which require secondary treatment for urban agglomerations. The plant's scale places it in a category where treatment processes typically include biological treatment to meet Class 1A or 1B discharge standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The plant discharges treated effluent into local waterways that eventually drain into the Hai River basin, which flows into the Bohai Sea. The receiving waters support agricultural irrigation and aquatic ecosystems, making proper treatment essential for protecting downstream water quality and regional ecological health.
Environmental context
The plant's treated effluent flows into local rivers within the Hai River basin, which ultimately discharges into the Bohai Sea. This watershed supports diverse aquatic life and is used for agricultural irrigation downstream. The region's flat terrain and seasonal precipitation patterns influence dilution capacity, making consistent treatment important for maintaining water quality in receiving streams.
