Abstract

The invention provides an automatic sludge processing device and method. The device comprises a processing box, a screening area, a layering area and an outputting area are sequentially divided from top to bottom in the processing box, and a main shaft is vertically and rotatably arranged in the processing box; a screening mechanism is arranged in the screening area, and a feeding mechanism is arranged in the screening area and located below the screening mechanism; a layering mechanism is arranged in the layering area, and a driving mechanism is arranged on the top of the processing box; according to the equipment, waste impurities containing water are output to the screening area, and the waste impurities are stirred and screened by a magnetic rotary screening rod, so that magnetic metalin the waste impurities is absorbed by the screening rod, then the waste impurities which are precipitated and layered are pressed, water is discharged, the separating discharging of the magnetic metal and waste water in the waste impurities is achieved, and the automatic discharging of waste water with magnetic metal in the waste impurities is achieved.

Description

Technical field [0001] The invention relates to the technical field of sludge reuse treatment, in particular to an automatic sludge treatment equipment and method. Background technique [0002] Sewage treatment plants in large and medium-sized cities in China were constructed earlier. Since there was no mature and feasible sludge treatment technology in China at that time, the sludge produced by the sewage treatment plants was temporarily stacked on the reserved land. With the passage of time, the amount of sludge piled up continues to increase. During the process of containment, shoveling, and filling of ditch, the debris in the sludge also increases. Construction waste, plant waste, and domestic waste are all mixed with it. Disposal is difficult; at the same time, the nature of the sludge determines that it cannot be dried. The moisture content of long-term stacking is still high. The average moisture content of 81.48% has been tested, showing a swamp shape, some jelly blocks, ...
