[0030] This specific embodiment achieves dehydration of the mud through the cooperation of the traveling sludge suction machine 2, the sludge pool 5, the conveying pump 4 and the sludge dewatering machine 10, instead of drying the mud to remove moisture, effectively improving the processing efficiency. In addition, the iron-containing material after dehydration is relatively dry, which is convenient for transportation and avoids secondary pollution in the mining area.

[0031] like Figure 1As shown, in order to better perform solid-liquid separation, in this specific embodiment, the conveying pipe 6 is also connected to the flocculant dosing device 7.

[0032] In this specific embodiment, the sludge dewatering machine 10 adopts a belt filter press, which includes a gravity dewatering device, a screen drum and a drum filter belt extrusion dewatering device connected in sequence. The gravity dewatering device, the screen drum and the drum filter belt extrusion dewatering device share a water collection tank 3.
