| description | The invention relates to sequencing batch sludge deep dewatering equipment and method adopting electroosmosis. The equipment comprises a closed frame, wherein an anode assembly and a cathode assembly are arranged in the frame; the cathode assembly comprises a driving wheel set supported at the lower part of the frame, the driving wheel set is sleeved with annular cathode filter cloth connected end to end, and cathode plates are arranged on the inner side of the cathode filter cloth; the anode assembly comprises a group of anode plates opposite to the cathode plates and a fixed seat supported at the upper part of the frame, and the anode plates are supported on the fixed seat respectively through driving pieces; anode filter cloth is arranged on one side, back to the corresponding driving piece, of each anode plate; sludge treatment space is formed between the anode plates and the cathode plates; and a middle layer and a surface active layer are arranged on the surface of each anode plate sequentially. The method comprises a start stage, a normal circulation work stage and an end stage. The service life of an anode can be prolonged, the electric energy consumption can be reduced, and biochemical sludge with the moisture content of 80%-85% can be dewatered until the moisture content reaches 55%-60%. |
