AI Technical Summary
Technical Problem
In existing technologies, sludge from water conservancy project ditches is not completely dried after treatment, which affects its reuse performance and may lead to environmental pollution. Mechanical squeezing cannot effectively remove bound water from the sludge cake.
Method used
The method combines mechanical extrusion and electro-osmotic filtration. The mechanical extrusion initially removes free water, while the electro-osmotic filtration uses an electric field to precisely remove bound water, resulting in extreme depth dehydration.
Benefits of technology
It achieves complete drying of sludge, ensures the reusability of sludge cake, avoids environmental pollution, and achieves the ultimate dewatering effect.

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.
