The Western Wastewater Treatment Plant Project in Lijin County

The Western Wastewater Treatment Plant Project in Lijin County has a treatment capacity of 40,000 m3/day. The influent to the ozone catalytic advanced oxidation tank is the effluent from the upstream processes of the sewage treatment plant, which include the magnetic flocculation sedimentation tank and the activated sand filter. After preliminary treatment and extended biochemical treatment, a large portion of biodegradable and readily biodegradable organic pollutants are degraded. However, trace amounts of organic matter remaining in the water still affect the compliance of the treated wastewater. The organic concentration in the wastewater remains relatively high, making treatment challenging. Longantai Enviro. applies its independently developed multi-stage catalytic oxidation technology to efficiently remove the residual refractory pollutants. The project requires that the influent water quality be COD ≤ 55 mg/L and pH 6 ~ 9, with the treated effluent achieving a water quality of COD ≤ 40 mg/L and pH 6~9.

Wastewater Quality:The wastewater contains refractory organic pollutants, making treatment challenging

Influent Water Volume : 40000m3/d

Process Description:The main construction components include a regulation tank, accident tank, magnetic flocculation sedimentation tank, activated sand filter, ozone catalytic oxidation tank, contact disinfection tank, ozone preparation workshop, sludge dewatering room, sludge drying workshop, and odor treatment unit.
