The water inlet pipe 3 that is provided with at housing 1 top penetrates water distributor 13 is set on the end in the housing 1, and water distributor 13 is annular perforations tubular type or spray-type, is centered around around the membrane module cylindrical shell 24, and is positioned at the composite filtering material top.The outer end of water inlet pipe 3 also connects a recoil rising pipe 5, is controlled respectively by the entering water electromagnetic valve 2 and the water solenoid valve 4 that recoils out.The bottom of composite filtering material also is provided with annular back flushing water pipe 6 in housing 1, is centered around around the membrane module cylindrical shell 24, and back flushing water pipe 6 links to each other with second backflushing water intake pipe 17, by 16 controls of second backwashing intake valve.
On back up pad 18, have permeable hole, in the bottom of back up pad 18 bracing frame 20 is set, bracing frame 20 upper ends link to each other with back up pad 18, and the lower end links to each other with housing 1 bottom.Connect blow-down pipe 23 in housing 1 bottom tip, blow-down pipe SV 22 is set on the blow-down pipe 23.
The PLC circuit is connected in the water treating device configuration self-con-tained unit, above-mentioned each SV, air compressor machine, suction filter pump, recoil pump and water treating device self-con-tained unit, can control normal water inlet, water outlet, back flushing automatically.
The processing mechanism of water treating device of the present invention:
A. filteration
This water treating device filtrate (biological fiber ball and charcoal, high-density fiber silk and high density active charcoal) particle is tiny, has the mechanical retention effect.Because of effluent stream through the time, filtrate is compaction state, utilizes the particle diameter of filter medium features of smaller, holds back the suspended substance in the sewage in large quantities.
B. adsorption
Charcoal of this water treating device or high density active charcoal have bigger porosity and specific surface area, can adsorb the suitable molecule of particle diameter.Remove organism, reduce COD and colourity etc.
C. bio-oxidation and biological adsorption
When being used for water treatment, the filter material surface of this water treating device microbial film of growing is because the specific surface area of filtrate is big, so the big concentration height of biofilm biomass carries out aeration by distribution device, for mikrobe provides oxygen.This water treating device need carry out back flushing after operation for some time.Because of constantly back flushing, microbial film is able to effective renewal, and biomembrane activity is very high.Highly active microbial film not only is embodied in bio-oxidation, degraded aspect, more shows as biofloculation, adsorption.To the material of some difficult degradations, can it be adsorbed, be trapped in wherein, be able to remove.
D. membrane sepn effect
The membrane sepn effect is to lean on certain pressure to accomplish as motivating force.Micro-filtration can be removed bacterium, virus and Parasites etc., also can reduce the phosphate content in the water.Ultrafiltration is used to remove macromole.R-o-is used to reduce salinity and removes total dissolved solidss.
The principle of work of water treating device of the present invention:
When being used for water treatment; Water inlet is got into the skin of water treating device by water inlet pipe 3; Behind water distributor 13 water distribution uniformities; Biological fiber ball 14 zones, upper strata of flowing through earlier, characteristic and the growth microbial film above that utilizes biological fiber ball 14 itself to sewage filter, effects such as bio-oxidation, biological absorption and biofloculation purify water.Then; Water gets into charcoal 15 zones, bottom; Characteristic and the growth microbial film above that utilizes charcoal 15 itself to sewage adsorb, effects such as bio-oxidation, biofloculation, filtration purify water; The required oxygen of mikrobe is carried through the air-supply duct 8 perforated pipe aerators 19 of bottom by air compressor machine, and air capacity is by pressure lock 7 controls of bottom.Then the outer treat effluent of water treating device gets into internal layer by the bottom, because pollutent is further removed in the centrifugation of membrane module 21 and suction filter pump, guarantees that water outlet reaches the reuse requirement at internal layer.Final treat effluent is discharged by the rising pipe 10 on housing 1 top, and the entire treatment process is accomplished.During works better, backflushing water intake pipe SV 16 on the recoil of first on first backflushing water intake pipe 12 entering water electromagnetic valve 11, second backflushing water intake pipe 17 and the back flushing on the recoil rising pipe 5 go out water solenoid valve 4 and all close.This water treating device is after operation for some time; Because resistance increases or change of water quality, need carry out back flushing, during back flushing; Earlier with entering water electromagnetic valve 2 with go out water solenoid valve 9 and close; Open recoil outlet valve 4, open the first recoil entering water electromagnetic valve 11 and the second recoil entering water electromagnetic valve 16 again, membrane module cylindrical shell 24 skins that one water is got in the housing 1 by second backflushing water intake pipe 17; Gas gets into housing 1 interior membrane module cylindrical shell 24 skins by air-supply duct 8 composite filtering material is carried out back flushing, and another strand water gets into membrane modules 21 by first backflushing water intake pipe 12 it is carried out back flushing.The back flushing water outlet is then discharged by back flushing rising pipe 5, and whole backwash process is accomplished.
When being used for the drink water purifying processing, the path of water is same as described above, and different is: composite filtering material is that the upper strata is the high-density fiber silk, and lower floor is the high density active charcoal; Air feeder is closed when works better, just opens when having only back flushing.
Water treating device of the present invention both can be used for the middle water treatment of sewage and trade effluent, also can be used for the purifying treatment of tap water.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention is not limited to above-mentioned giving an example, those skilled in the art, and in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
