Flocculating agent feeding device is comprised of molten medicine-chest, dispensing kit, volume pump, and dispensing kit is connected with line mixer with the volume pump on pipeline by pipeline.
Compared with the prior art, this device is comprised of flocculating agent feeding device, line mixer, integrated high turbidity water purifier and PLC controller.Flocculating agent feeding device is comprised of molten medicine-chest, dispensing kit, volume pump; Integrated high turbidity water-purifying device by cyclone reaction, suspending clarification, tube settling, top scrape that slag, mud are concentrated, the operation such as filtration and filtered water tank forms.It has the following advantages: the first, and because the technique packing of Sweet natural gas acetylene processed is put difference, the carbon black in the carbon black waste water of generation is existing hydrophilic, has again hydrophobicly, and this device all can be processed the carbon black in waste water; The second, because the technique packing of Sweet natural gas acetylene processed is put difference, the specific gravity of black of generation differs, generally between 0.8 * 10
3-1.05 * 10
3kg/m
3, carbon black concentration is up to 3000mg/L, and contains petroleum-type concentration and reach 50 mg/L, and this device all can effectively be removed carbon black and petroleum-type; The 3rd, carbon black waste water is scraped through line mixer high efficient mixed, cyclone reaction, suspending clarification, tube settling, top after the operations such as the concentrated and filtration of slag, mud process by adding flocculation agent, water outlet carbon black concentration≤20mg/L, suspended substance (SS)≤20mg/L, petroleum-type≤1mg/L, far below < < integrated wastewater discharge standard > > GB8978-1996 first discharge standard; The 4th, this device has energy consumption and reagent consumption is low, and floor space is little, invest little, the feature such as purification efficiency is high, and effluent quality is good.
