Accompanying drawing explanation
below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in more detail:
fig. 1 is the process flow diagram using the utility model Treated sewage reusing treatment facility to purify waste water.
Embodiment
below in conjunction with specific embodiment, the utility model is described in more detail, but be not limited to these embodiments.
Embodiment
the present embodiment purifies the sewage of certain enterprise with Treated sewage reusing treatment facility of the present utility model, and process flow diagram as shown in Figure 1.
see Fig. 1, the utility model Treated sewage reusing treatment facility comprises by the former pond 1 of pipeline sequential communication, self-cleaning filter 2, ultra-filtration equipment 3, ultrafiltration pond 4, topping-up pump 5, cartridge filter 6, reverse osmosis filter 7 and reuse pool 8; This Treated sewage reusing treatment facility also comprises the first dense pond 10 and the second dense pond 11; Described ultra-filtration equipment 3 has two water outlets, and one of them water outlet is connected with ultrafiltration pond 4, and another water outlet is connected with the first dense pond 10; Described reverse osmosis filter 7 has two water outlets, and one of them water outlet is connected with reuse pool 8, and another water outlet is connected with the second dense pond 11; Described Treated sewage reusing treatment facility also comprises the medicine system 9 for adding the medicament such as Scale inhibitors or sterilant, medicine system 9 has two drug feeding pipeline, one of them drug feeding pipeline communicates with the pipeline between self-cleaning filter 2 and ultra-filtration equipment 3, and another drug feeding pipeline is connected with the pipeline between topping-up pump 5 and cartridge filter 6.
wherein, be also provided with one between ultrafiltration pond 4 and ultra-filtration equipment 3 and ultra-filtration equipment 3 carried out to the Backwash pipeline of back flushing for the part water in ultrafiltration pond 4 is recycled to ultra-filtration equipment 3.The strainer filtering precision of self-cleaning filter 2 is 100 microns.The filtering membrane that ultra-filtration equipment 3 uses for aperture be the Pvdf Microporous Hollow Fiber Membrane of 0.03 micron.Cartridge filter 6 uses the polypropylene filter core in 5 microns, aperture.
the self-cleaning filter used in the present embodiment is commercial products, and it is while filter sewage incessantly, can carry out automatization cleaning by controlling the pressure difference of filter screen both sides.
the ultra-filtration equipment used is commercial products, and filter membrane is acid and alkali-resistance polyvinylidene difluoride (PVDF) (PVDF) hollow-fibre membrane in 0.03 micron, aperture, and working pressure is 0.2MPa, and within every 30 minutes, needs carry out back flushing once, and the time is 1 minute.Water purification (namely through the permeate of the ultra-filtration membrane) producing water ratio of this ultra-filtration equipment is 90%, also can the dense water (being namely trapped in the concentrated solution of ultra-filtration membrane side) of output 10%, and water purification and dense moisture two water outlets are discharged.
the cartridge filter used is commercial products, and its uses aperture to be polypropylene (PP) filter core of 5 microns, in the surface that trace suspension particle, colloid, microorganism etc. during filtration in water body were trapped or were adsorbed on filter core and hole; After filtering for some time, the running resistance of filter core can rise gradually, when moving to import and export differential water pressures and reaching 0.1MPa, needs in time more renew cartridge.Cartridge filter efficiency is high, resistance is little, is convenient to change, and mainly plays the effect of the reverse osmosis filter of protection rear end, if prevent the ultra-filtration membrane of front end ultra-filtration equipment from occurring fracture of wire and affecting the normal operation of reverse osmosis filter.
the reverse osmosis filter used also is commercial products, it can play the effects such as desalination, decolouring, reduction hardness, the producing water ratio of water purification about 65%, the water purification of output can direct reuse in production, and the dense water of output gets final product qualified discharge after simple process further.
in the present embodiment, the former water in former pond 1 is the comparatively clean water body obtained after certain pre-treatment by the sewage that enterprise discharges.First water in former pond 1 flow through in self-cleaning filter 2 and filter, and then enter in ultra-filtration equipment 3 and carry out ultrafiltration, before entering ultra-filtration equipment 3 ultrafiltration, must add sterilant by medicine system 9 in water body.The water purification of ultrafiltration output 90% flows in ultrafiltration pond 4, the dense water of output 10% then flows in the first dense pond 10 in addition, dense water in first dense pond 10 accumulate to a certain amount of after, the sewage that can discharge with enterprise merges, and delivers in former pond 1 after re-starting pre-treatment again.Water in ultrafiltration pond 4 pumps into cartridge filter 6 mainly through topping-up pump 5 and filters, and before entering cartridge filter 6, medicine system 9 controls to add Scale inhibitors in water body; And the sub-fraction water in ultrafiltration pond 4 can also be recycled to ultra-filtration equipment 3 for back flushing.Water after cartridge filter 6 filters flows in reverse osmosis filter 7 and filters further, and the water purification of osmosis filtration output about about 65% flows in reuse pool 8, and the dense water of other about 35% is discharged in the second dense pond 11.Water in reuse pool 8 can direct reuse in productive life, the sewage that the water in the second dense pond 11 can discharge with enterprise merges, and delivers in former pond after re-starting pre-treatment again, also can through simple process further and direct discharge up to standard.
following table is several groups of sewage disposal performance index contrasts using the present embodiment Treated sewage reusing treatment facility.
note: water inlet refers to the water in former pond, product water refers to the water in reuse pool, and COD refers to chemical oxygen demand, and TDS refers to total dissolved solid.
can be found out by upper table data, utilize the reuse water of the utility model Treated sewage reusing treatment facility process gained, its water quality is better than tap water quality, can direct reuse in productive life.
above the utility model is described in detail; its object is to allow the personage being familiar with this art can understand content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to spirit of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
