Jinan Liyang Lake Water Ecological Comprehensive Treatment Project mainly treats the discharged water from Daming Lake to ensure that the water quality entering Liyang Lake meets the Class III surface water quality standard and satisfies the landscape water storage requirements of Liyang Lake. In response to the water quality issues of the replenishment water source, the Liyang Lake Water Treatment Station adopts a treatment process consisting primarily of primary sedimentation + high‑efficiency algae treatment system + dissolved air flotation (DAF) + ultraviolet disinfection. The designed treatment capacity is 10,000 m³/d, with a self‑consumption coefficient of 1.05. The treatment volume is adjusted according to the quality of the incoming water, and the effluent water quality reaches the Class III standard specified in the Environmental Quality Standards for Surface Water (GB3838‑2002). The project mainly consists of an intake pump house, a primary sedimentation tank, a high‑efficiency algae treatment tank, a dissolved air flotation tank, an ultraviolet disinfection channel, a landscaped outlet, an administration building, and inlet/outlet pipelines.
