A water conservancy ditch sludge treatment device and a treatment method thereof

Abstract

The application relates to a water conservancy ditch sludge treatment device and a treatment method thereof, which comprises a sludge collecting mechanism for collecting and flocculating sludge, a mechanical extrusion mechanism for extruding flocculated sludge water and forming a mud cake to discharge free water in the sludge, and an electro-osmotic water filtering mechanism for continuously filtering water in the ice by the electro-osmotic mode to discharge bound water in the mud cake. The mechanical extrusion mechanism comprises a filter chamber for extruding water after collecting flocculated sludge water, a collecting assembly for collecting water at the bottom of the filter chamber, and a judging assembly for monitoring the flow rate of the mechanical extrusion water. If the flow rate is lower than a preset threshold value, it is determined that mechanical dewatering reaches the limit, the mechanical filter chamber bottom water outlet is closed, and the electro-osmotic water filtering mechanism is opened. The mechanical extrusion and the electro-osmotic mode are matched with each other, the effect of fully discharging sludge water is realized, and the efficiency of sludge recycling is improved.
