Hebei Wastewater Treatment Plant, Qinhuangdao, Hebei Province, China

The Hebei wastewater treatment plant is located in Qinhuangdao City, Hebei Province, China, serving a population of approximately 210,000. The plant has a designed capacity of 1.00, indicating its scale in managing municipal wastewater for this coastal urban area. As a facility in China, the plant operates under national wastewater discharge standards, which typically require secondary treatment for urban wastewater. For agglomerations of this size, Chinese regulations mandate compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits on key pollutants. The plant's proximity to the coast (within 50 km) means its treated effluent likely discharges into a river or directly into the Bohai Sea, a semi-enclosed marginal sea. The Bohai Sea supports diverse marine life and is an important fishing ground, making proper treatment essential to protect coastal water quality and ecosystems.

The plant is located in Qinhuangdao, a coastal city on the Bohai Sea. Treated wastewater likely discharges into local rivers that flow into the Bohai Sea, a semi-enclosed sea with limited water exchange. The Bohai Sea supports important fisheries and marine biodiversity, making nutrient and pollutant control critical to prevent eutrophication and habitat degradation.
