Environmental context
The plant discharges into the Yellow Sea via local rivers and Dalian Bay. The Bohai Sea, a semi-enclosed marginal sea, receives effluent from multiple coastal cities and is ecologically sensitive due to limited water exchange. The area supports diverse marine life, including fish and shellfish, and is an important migratory corridor for seabirds. Proper treatment is critical to prevent eutrophication and protect coastal habitats.
