Overview
Hebei wastewater treatment plant serves 62,000 people in Qinhuangdao, Hebei, China. Located within 50 km of the coast, it discharges into the Bohai Sea via local waterways.
The Hebei wastewater treatment plant is located in the Haigang District of Qinhuangdao, a coastal city in Hebei Province, China. It serves a population of approximately 62,000, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. The plant is situated in the urban area of Qinhuangdao, which is a major port city on the Bohai Sea. Under China's national wastewater discharge standards, plants serving populations of this scale are typically required to meet Class 1-A or Class 1-B effluent limits under the GB 18918-2002 standard, which mandates secondary treatment with nutrient removal for sensitive water bodies. The designed capacity is 1.00 (likely in units of 10,000 m³/d or similar), indicating the plant's intended throughput. The plant's treated effluent ultimately reaches the Bohai Sea, a semi-enclosed marginal sea that is ecologically significant for its fisheries and marine biodiversity. The Bohai Sea receives discharges from multiple rivers and coastal cities, making nutrient management critical to prevent eutrophication and algal blooms. The plant's location within 50 km of the coast underscores its role in protecting coastal water quality.
Environmental context
The Hebei plant discharges into the Bohai Sea via local rivers and drainage channels in the Qinhuangdao area. The Bohai Sea is a shallow, semi-enclosed sea that supports important fisheries and migratory bird habitats. Nutrient loading from urban wastewater can contribute to eutrophication and hypoxia in coastal waters, making effective treatment essential for maintaining ecological balance in this sensitive marine environment.
