Landfill leachate is collected in adjustment tanks and then processed with the Loading Coagulation Magnetic Separation Water Treatment Technology, by which the harmful substances will be removed. The processed leachate will then undergo biochemical treatment in highly efficient anaerobic reactors (ABR), by which organic pollutants will be substantially removed. Finally, the residual refractory substances in the water will be removed by the MBR and advanced oxidation techniques, so that the treated effluent shall meet Grade 1 Standard of the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste.
