Background

At present, most of the treatment of coal washing water adopts a method of adding a flocculating agent into the coal washing water, then concentrating by adopting a thickener, and then carrying out vacuum filtration or plate-and-frame filter pressing. Two newer methods are disclosed in the technical literature on coal dressing: one is an electrochemical dehydration method, and the other is a pressurized upper float method. The former separates coal particles with extremely fine water in coal washing water by an electrochemical method by utilizing the properties of electric load on the surface of coal slime particles and main positive charge of water molecules; the main principle of the latter is that air is pressed into water to prepare air-containing water saturated with air, then the air is in contact with coal washing water in an upper floating tank, the air in the water is released immediately and is adhered to the surface of fine coal particles to enable the fine coal particles to float upwards, and then the fine coal particles are scraped out by a scraper to purify water. Still other techniques employ sulfuric or hydrochloric acid to adjust the pH of the coal wash to 6.0-7.5. The method has the advantages that equipment is simple, the flow is short, but the method has the biggest defects that chemical reagent hydrochloric acid or sulfuric acid is added into water, the coal washing water is polluted by new water due to improper use and treatment, the filter medium needs to be replaced periodically, and the cost is increased.
