Embodiment
As shown in Figure 1, the present invention mainly is made up of water inlet system, dissolved air flotation system, dissolved air water system, treating water gathering system and scum silica frost removal system.Wherein:
1, water inlet system: be made up of water absorption tube 3, water inlet pipe 5 before raw water box 1, intake pump 2, the pump, the present invention sets up hydraulic mixer 4 before water inlet pipe 5.
2, dissolved air flotation system (agent set): by profile is right cylinder 15, and device is inner to be made up of zone of action 12, disengaging zone 14, and the present invention is provided with perforation header 13 and bottom umbrella mixing tank 11 in bottom of device.
3, dissolved air water system: this system is improvements of the present invention, and it is made up of ozonizer 17, ozone tail pipe 18, ozone pressure-reducing cushioning device 22, pressure transmitter 23, decompression relief valve 24, return line 21, ozone air dissolved pump 8, buffer tank 7 and dissolved air water pipe 6.
4, treating water system: be made up of perforation header 13, rising pipe 20, the present invention is provided with the magnetic valve 9 and the time relay 10.
5, scum silica frost system: back taper scum silica frost district 19, scum pipe 16 are formed, and the present invention is provided with the magnetic valve 9 and the time relay 10.
Former water extracts from raw water box 1 by intake pump 2, adds emulsion splitter or coagulating agent in the water absorption tube 3 before pump, and enter water inlet pipe 5 behind the thorough mixing in hydraulic mixer 4; Treating water is collected into rising pipe 20 by the perforation header 13 of dissolved air flotation device 15 bottoms, effluxes via magnetic valve 9; Magnetic valve 9 is realized the automatic control of switching by the time relay 10; The ozone that ozonizer 17 produces enters decompression in the ozone pressure-reducing cushioning device 22 by ozone pipeline 18, is mixed by 8 suctions of ozone air dissolved pump jointly with a part for the treatment of water (recirculation water) then and enters in the dissolved air water pipe 6 by buffer tank 7; Former water behind breakdown of emulsion or the coagulation is by water inlet pipe 5, dissolved air water enters dissolved air flotation device 15 by dissolved air water pipe 6, enter contact reacts district 12 behind umbrella mixing tank 11 place's thorough mixing of bottom, dissolved air water enters disengaging zone 14 after discharging pollutent contact reacts behind ozone microbubble and breakdown of emulsion or the coagulation.Pollutent is attached to the ozone microbubble and enters scum silica frost district 19, and treating water then effluxes by bottom perforated header 13; Scum layer in the scum silica frost district 14 is thickening gradually in time, and when reaching certain thickness, the time relay 10 is by default time action, magnetic valve 9 cuts out, dissolved air flotation device 15 median water level rise, and scum silica frost is squeezed in the back taper scum silica frost district 19 at top, effluxes via scum silica frost purger 16 at last; When discharging finished, the time relay 10 was by default time action, and magnetic valve 9 is opened again, enters the next work period.
Cause dissolved air flotation device 15 pressure fluctuating in inner in order to prevent current from effluxing, perforation header 13 is according to the non-homogeneous layout of water (flow) direction.
The adaptation procedure of ozone oxidation of the present invention and air-dissolving air-float is achieved in that
Molten tolerance of the present invention can be controlled inlet gas ozone concentration by the generating capacity of regulating ozonizer 17.Directly suck gas the ozone pipeline 18 and form air bag or cause in the follow-up dissolved air flotation device pressure surge etc. by negative pressure in the pump for fear of air dissolved pump 8 from having to press, the present invention is provided with ozone pressure-reducing cushioning device 22 behind ozone pipeline 18, under the effect of pressure transmitter 23, realize decompression automatically, thereby reduce the gaseous tension that enters air dissolved pump 8 by decompression relief valve 24.Dissolved air water is adjusted the dissolved air water pressure that enters the dissolved air flotation device by buffer tank 7, to avoid the pressure surge in the dissolved air flotation device 15.Dissolved air water is by dissolved air water pipe 6, former water behind breakdown of emulsion or the coagulation is realized thorough mixing by the umbrella mixing tank 11 that water inlet pipe 5 subtends enter dissolved air flotation device 15 bottoms, the ozone microbubble that discharges in the dissolved air water carries out the catalytic oxidation of pollutent in adhering contaminant, thereby realizes the best-fit of ozone oxidation and air-dissolving air-float.
Working process of the present invention is as follows:
1. water inlet dosing coagulant or emulsion splitter before water pump 1 finished the coagulation or the breakdown of emulsion process of pollutent by hydraulic mixer 4;
2. treating water partial reflux and aspirated by air dissolved pump 8, the ozone gas that ozonizer 17 produces is reduced to normal pressure through the effect of ozone pressure-reducing cushioning device 22, and the suction function that produces by air dissolved pump 8 sucks
Pump?In, carry out air water with recirculation water and be mixed into pressure air-dissolving water, undertaken entering dissolved air flotation device 15 after pressure is regulated by buffer tank 7 then;
3. former water behind coagulation or the breakdown of emulsion and ozone dissolved air water enter zone of action 12 behind dissolved air flotation device 15 bottom thorough mixing, the ozone microbubble that discharges in the dissolved air water and water pollutant contact wetting with carry out that ozone contacts and oxidizing reaction when adhesion waits materializing procedure;
4. 12 current that rise enter flotation separation zone 14 and finish solid-liquid separation from the air supporting zone of action, and pollutent is carried by microbubble and enters 19 tops, scum silica frost district, and treating water is collected from bottom perforated header 13 and effluxed;
When scum silica frost in scum layer, assemble reach certain thickness after, under the effect of the time relay 10, magnetic valve 9 cuts out, and stops treating water and effluxes, water level constantly rises in the device, scum silica frost is clamp-oned inverted upper taper scum silica frost district 14 and effluxes by the scum silica frost purger;
6. after scum silica frost was got rid of fully, under the effect of the time relay 10, magnetic valve 9 was opened again, and the beginning treating water effluxes, and separator 15 waters surface drop to ordinary water-level gradually.
