Hebei Wastewater Treatment Plant, Luquan District, Shijiazhuang

The Hebei wastewater treatment plant is located in Luquan District, Shijiazhuang, Hebei Province, China. It serves a population of approximately 82,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For a plant of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into local water bodies that eventually drain into the Hai River system, which flows into the Bohai Sea. The Hai River basin is a heavily urbanized and industrialized region, making effective wastewater treatment critical for protecting downstream aquatic ecosystems and coastal water quality in the Bohai Sea.

The plant discharges into the Hai River basin, which flows through Hebei Province and Tianjin before reaching the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea that supports fisheries and marine biodiversity but faces eutrophication pressures from upstream nutrient loads. Effective treatment at this plant helps reduce pollutant loads entering the river system and ultimately the sea.
