Possible non-applicable to the waste water and sewage treatment - fouling electrolyzer

摘要

An electrolysis apparatus is provided to enhance the electrolysis efficiency outstandingly by treating recalcitrant materials in sewage and wastewater by electrolysis, and mechanically removing scale generated on a cathode due to the ion adsorption using disc type electrodes during the electrolysis. A non-fouling electrolysis apparatus applicable to wastewater and sewage treatment comprises: a bottom plate(1); two side plates(2,2') vertically installed on the bottom plate; a front plate(3) and a rear plate(4) installed on front and rear parts of the side plates; an inlet(5) formed on the front plate, and an outlet(6) formed on the rear plate; a plurality of partition plates(7) vertically inserted into a plurality of slots(2001) to divide an inner part surrounded by the above plates into a plurality of space parts such that sewage or wastewater passes through the space parts, the slots being formed on inner portions of the side plates; disc type electrodes(8) with a negative polarity and fixed flat plate type electrodes(9) with a positive polarity alternately installed in one of the space parts divided by the partition plates such that the disc type electrodes and the fixed flat plate type electrodes are spaced apart from each other to electrolyze the sewage or wastewater, the disc type electrodes being rotated oppositely to the effluent flowing direction; and a scraper(20) installed on top parts of the disc type electrodes to remove scale.
