Overview
Hebei wastewater treatment plant serves 222,200 people in Lunan District, Tangshan, Hebei, China. The facility operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Lunan District, Tangshan, Hebei Province, China, serving a population of 222,200. The facility is part of the municipal wastewater infrastructure for the Tangshan metropolitan area. As a large-scale plant serving over 200,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. The plant's designed capacity is 1.00 (likely in 10,000 m³/d or similar units), indicating substantial treatment capability. The plant discharges treated effluent into local waterways that ultimately drain into the Bohai Sea via the Luan River system. The Bohai Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries and marine biodiversity. Proper treatment is critical to prevent eutrophication and protect coastal water quality.
Environmental context
The plant's treated effluent flows into the Luan River basin, which drains into the Bohai Sea, a semi-enclosed sea with limited water exchange. The Bohai Sea supports important fisheries and migratory bird habitats. Nutrient loading from urban wastewater can contribute to algal blooms and hypoxia, making advanced treatment essential for protecting this sensitive marine environment.
Frequently asked questions
The Hebei wastewater treatment plant is located in Lunan District, Tangshan, Hebei Province, China, at approximately 39.608°N, 118.131°E.
The Hebei WWTP serves a population of 222,200 people in the Lunan District and surrounding areas of Tangshan.
The plant discharges treated effluent into the Luan River system, which flows into the Bohai Sea. The discharge is regulated under China's national wastewater discharge standards.
The Hebei WWTP operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for pollutants like COD, BOD, and nutrients. Plants serving over 100,000 people typically require secondary treatment with nutrient removal.
For a plant of this scale in China, secondary treatment with biological nutrient removal is standard to meet GB 18918-2002 standards, especially if discharging into sensitive water bodies like the Bohai Sea.
