Air-flotation type separating reaction apparatus for treating sewage is to use the core pollution treatment medicament of the compound high-efficiency flocculating agent of original creation invention as the sewage solid/liquid separation; The mixing of being finished flocculation agent by air-flotation type separating reaction apparatus for treating sewage adds, and finishes separation to the severe polluted water, purification etc. and administers technical operation.
Because of flocculation agent is a powdery product, before blending in sewage, must be prepared into certain density flocculation agent lysate by lysate agitator 21.The concentration outfit ratio of flocculation agent lysate is: 1 part of flocculation agent powder quality share, add 49 parts of dilution tap water quality shares.Preparation flocculation agent lysate is finished by lysate agitator 21; The running technology parameter is: agitator velocity of rotation: 〉=45r/min; Churning time: 〉=25min; Heating and temperature control is at 40～50 ℃.Have certain density flocculation agent lysate prepare qualified after, the lysate of packing into adds in the container for storing liquid 22 of volume pump 23 standby.Sewage quantity to be processed as required during use, with the part by weight of 1:10, the pressure that adds with 〉=0.15Mpa evenly is expelled in the duct type mixing tank 24 of effluent stream warp continuously.
Produce the need of discharging and dispose of sewage, all will send in the permanent position water tank 19 of setting by sewer line 18.Simultaneously, the dip hatch oralia is arranged, effusive need from the water tank 19 of permanent position are disposed of sewage, carry out the aperture metering in the water outlet design and installation of permanent position water tank.Through the sewage of aperture metering, when flowing through duct type mixing tank 24, and add the flocculation agent lysates that volume pump 23 evenly is injected into continuously with constant rate, realized in duct type mixing tank 24 uniform mixing in proportion.At this moment, the flocculation agent in need disposing of sewage uses does matter content, reaches 2 ‰ effective concentration of the utility model design.In duct type mixing tank 24, through containing flocculation agent sewage behind the uniform mixing in proportion, be sent to the intravital Reaction Separation of air-flotation type separating reaction apparatus for treating sewage jar district 9 by pipeline 26, accept isolation of purified and handle.
In duct type mixing tank 24 blending the sewage of flocculation agent, be sent in the Reaction Separation district 9 by sewage inlet pipe 26.Meanwhile, liquid chlorine in the liquid chlorine storage bottle 29, in rotor chlorinating machine 27 injecting compressed air pipelines 6, mix with the pressurized air dissolving that air driven pump 28 produces, produce chloride pressurized gas, after gas enters pipe 6 and aerating pore scatterer 8, in the sewage that enters Reaction Separation district 9, discharge with the microbubble form; The microbubble diameter generally all≤0.3mm.Chloride compressed-air actuated air demand, the unit volume of disposing of sewage with needs per hour expense serve as to calculate radix, contain dirty concentration according to sewage, generally are controlled at 0.5～0.8m
3/ m
3.h; The content of chlorine in pressurized air generally is controlled at 1:18～20; Chloride compressed air pressure generally is controlled at 0.05～0.08Mpa.Simultaneously, according to principal pollutant and specific pollutant different qualities, also in sewage, throw in required special pollution treatment medicament by being arranged on the auxiliary balling iron 25 on the sewage water inlet pipe 26.
Enter the sewage in Reaction Separation district 9, after comprehensive actions such as dioxygen oxidation reductive action, special pollution treatment medicament scrubbing reactivity, the centrifugation of flocculation agent adsorption-flocculation are handled in the chemical reduction reaction effect of available chlorine, pressurized air, the subparticle of generation; All kinds of inorganic substance that contain with sewage Central Plains and the subparticle of organic substance; Suspended substances such as the floc sedimentation that flocculation agent absorption, throwing out produce, wadding bar all with the microbubble recombine that produces, form the air float body formula scum silica frost of density less than water, at the buoyancy float downward to residual air scum silica frost district 16.
In residual air scum silica frost district 16, scum silica frost is scraped in the rotation of dregs scraper 13 dreg scrapers 12 and is swept down, is blown into scum silica frost vent pipe 11, has realized the solid/liquid separation of sewage.Scum silica frost after the separation is sent to precipitation by pipeline and removes in the mud sump 10, prepares to accept the otherwise processed of mud-water separation.
Sewage injects in Reaction Separation district 9 contains oxygen pressurized air, participate in processing reaction with the microbubble form to sewage after, residual gas is focused at the upper space in residual air scum silica frost district 16, discharges by venting port 15.In theory, chlorine is a kind of deleterious irritant gas, and when airborne chlorine gas concentration reached 40～60mg/L, the people breathes 0.5～1.0h in this environment just danger may occur; But chlorine particularly after the sewage water filtration dissolving, does not have again the chlorine that is detrimental to health to overflow through water.But be protection operator safety; prevent pollutant atmosphere; when design liquid chlorine add-on; just select to have designed the adding numerical value that is lower than the dangerous concentrations lower limit; simultaneously in the venting port design and installation chlorine residue Monitoring and Controlling instrument 14, monitor in real time by GB16297-1966 " discharge standard of air pollutants ".
The sewage that enters Reaction Separation district 9 is handled through combined reaction, realizes the liquid sewage that produces after the solid/liquid separation, by the own wt pressure adsorption filtration district 7 that flows through downwards.In adsorption filtration district 7 by the filtering layer of forming by filtrates such as gac, quartz sand, gravels, though to handling through solid/liquid separation, but in liquid sewage, still can contain suspended substances such as a spot of subparticle, heavy metal ion, and objectionable impurities such as COD, BOD, total phosphorus, total nitrogen, bacterium, virus, carry out degree of depth adsorption filtration purifying treatment.After adsorption filtration was handled, purifying waste water to flow to purified water reserve 4 and becomes reuse water; By rising pipe road junction 3, be sent to water reservoir 2 then.During use, extract out through the rising pipe 1 of water reservoir 2, directly deliver to each water unit with lift pump.
