Step 2: the hybrid reaction described in the mixed mixed medicine sewage of dosing enters by sump pump is total in the path hybrid reaction pipe 43 of the path hybrid reaction pipe assembly in condensed system, the dissolved air water that its gas-liquid mixing pump 48 produces adds an A and sewage dissolved air water under meter 23 to control add-on by dissolved air water, the ratio of its add-on accounts for 35% of total add-on, its dissolved air water adds a B and dissolved air water arm A under meter 52 to control add-on, and the ratio of its add-on accounts for 65% of total add-on; The mixed mixed medicine sewage of its dosing and dissolved air water bump in conjunction with generating a large amount of band gas flcos in condensed system altogether in hybrid reaction, then and the coagulant aids hybrid reaction adding by chemical feeding points D form the bubble of greater particle size and the copolymerized body of wadding grain, enter in common cohesion equipment for separating liquid from solid and separate;
Step 3: enter in the separator tube 69 in described common cohesion equipment for separating liquid from solid with the mixture of the copolymerized body of wadding grain when multiphase medium pump air dissolving system completes the bubble that mixes medicine sewage and dissolved air water hybrid reaction and form greater particle size, by the distribution pipe 70 of the multiple cone separators 71 on separator tube 69, the gas-solid-liquid mixture that needs are separated separates by multiple range of distribution independently, because bubble is larger with the density of copolymerized body and the density difference of water of wadding grain, particle in the mixed medicine sewage of particle diameter ratio is large, this copolymerized body automatic-ascending forms scum layer district 72 to separator tube 69 tops, by scum pipe, discharge, water after purification is collected by the perforation header 68 of the bottom of separator tube 69, then discharges by high-low position water shoot 75,78, open the water valve 79 on low level water shoot 78, now only scum silica frost is not arranged in draining, water valve 79 its high-order water shoots of closing on low level water shoot 78 start draining, regulate the pipe connecting on high-order water shoot 75 to make the elevation of water surface in header tank 77 be applicable to row's scum silica frost, be convenient to the row's of realization scum silica frost, complete after deslagging, open the water valve 79 on low level water shoot 78, carry out the draining of low level water shoot 78, so analogize, cyclical operation, controls the time that water valve 79 is opened, and realizes scum silica frost thickening.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; allly be familiar with those skilled in the art in technical scope disclosed by the invention, within being equal to and replacing or change protection scope of the present invention all should be encompassed according to technical scheme of the present invention and design of the present invention thereof.
