Overview
Hebei wastewater treatment plant serves Qinhuangdao, Hebei, China, with a designed capacity of 1.00 and a population served of 200,000. It is located within 50 km of the coast, impacting the Bohai Sea.
The Hebei wastewater treatment plant is located in Changli County, Qinhuangdao, Hebei Province, China. It serves a population of approximately 200,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant's designed capacity is 1. As a large-scale municipal facility, the plant is expected to meet national discharge standards under China's Water Pollution Prevention and Control Law. For agglomerations of this size, secondary treatment with nutrient removal is typically required, especially given the proximity to sensitive coastal waters. The plant's performance is likely monitored by local environmental authorities to ensure compliance with effluent limits. The treated wastewater from this plant ultimately discharges into the Bohai Sea via local rivers or drainage networks. The Bohai Sea is a semi-enclosed water body that supports fisheries, aquaculture, and maritime transport. Nutrient and pollutant loads from coastal plants like this one can contribute to eutrophication and algal blooms, making effective treatment critical for marine ecosystem health.
Environmental context
The Hebei plant discharges into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea receives freshwater from several rivers, including the Luanhe and Haihe, and supports diverse marine life, including fish, crustaceans, and migratory birds. Eutrophication from nutrient inputs is a concern, as it can lead to harmful algal blooms and hypoxic zones. The plant's location within 50 km of the coast underscores the importance of advanced treatment to protect this ecologically sensitive marine environment.
Frequently asked questions
The Hebei wastewater treatment plant is located in Changli County, Qinhuangdao, Hebei Province, China.
The plant serves approximately 200,000 people, classifying it as a large agglomeration under Chinese wastewater regulations.
The treated wastewater from the Hebei plant discharges into the Bohai Sea, likely via local rivers or drainage networks. The plant is within 50 km of the coast.
The plant operates under China's Water Pollution Prevention and Control Law, which sets discharge standards for municipal wastewater. Large agglomerations like this typically require secondary treatment with nutrient removal to protect coastal waters.
For a plant serving 200,000 people in China, secondary treatment with biological nutrient removal is standard. This helps reduce organic matter, nitrogen, and phosphorus before discharge into sensitive water bodies like the Bohai Sea.
