Reasons and treatments for thickener turbidity: First, strictly control the feed fineness to ensure stable feed amount, avoid sharp fluctuations in fineness and ore volume, and ensure smooth operation of the thickener; second, control the liquid-solid ratio to prevent turbidity caused by excessive liquid volume and high concentration; the best feed concentration for thickeners is 25%-30%; with the supplementary dilution of the supernatant of the thickener, the actual slurry concentration of the thickener can be maintained at around 18%-25%; at this concentration, the flocculation effect of the flocculant is the best; too high or too low a concentration is not conducive to the sedimentation of the ore;
The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
