Abstract

In view of the serious anodic corrosion and cumbersome installation of drainage equipment in the current electro-osmotic drainage method, a new type of conductive plastic drainage plate is proposed. The drainage plate can be quickly assembled into a horizontal electroosmotic drainage system, which saves time and solves the problems of electrode corrosion in the electro-osmotic process and the separation of electrode and sludge in the late electro-osmotic process. Taking the high-moisture content dredged sludge produced by Luojiagou dredging project in Fuyang City of Anhui Province as the research object, the double-layer horizontal electro-osmosis dewatering model tests are carried out by using the conductive plastic drainage plate. The test results show that the electro-osmotic drainage performance of the conductive plastic drainage plate is excellent, and the double-layer arrangement can obtain better electro-osmotic effect.
