Brief description of the drawings
Fig. 1 is the embodiment schematic diagram of acidproof ultra-filtration membrane device.
Specific embodiment
A kind of acidproof ultra-filtration membrane device that the utility model is provided is carried out in detail with specific embodiment below in conjunction with the accompanying drawings
Description.
Embodiment
Fig. 1 shows that a kind of acidproof ultra-filtration membrane device includes：Water tank 1, acidproof milipore filter group 3, product water tank 4, cleaning water tank 5
With surge tank 7, the water tank 1 connects the acidproof water inlet end of milipore filter group 3 by concentrated water valve 9；The acidproof water side of milipore filter group 3
The water conservation case 1 is connected by circulating pump 2.
Water tank 4 is produced in the connection cleaning water tank 5 of 1 overrich water valve of the water tank 9, the connection of water tank 5, is produced water tank 4 and is connected acidproof super
Filter membrane group 3.
Surge tank 7 is connected with the product water tank 4 and acidproof milipore filter group 3, wherein, intake valve 12 is set in surge tank 7
With air bleeding valve 13.
The acidproof water side of milipore filter group 3 connects cleaning water tank 5 by valve 10, and cleaning water tank 5 one end is by cleaning
Pump 6 simultaneously connects the acidproof water inlet end of milipore filter group 3 by producing penstock 11；Water tank 4 is produced in other end connection.
The water tank 1 also includes pump discharge valve 8.
The water inlet of the inlet water tank is that, by the water outlet after the disc type filtering of 100 μm of precision, disc filter can remove acid
Property waste water in particle diameter more than 100 μm of particulate matter, ensure follow-up milipore filter stable operation.Acid waste water and acid-resistant disintegration group 3
After concentrated water mixing acidproof milipore filter group is promoted to through circulating pump.Acid water pollution thing concentration constantly increases with the time in inlet water tank
It is long, it is evacuated to sludge treating system using sludge pump when concentration reaches certain concentration.
Further, in the acidproof milipore filter group 3, acidproof milipore filter is with film with the pressure differential of film both sides as driving force
Filter medium, under pressure, when stoste flows through film surface, the densely covered many tiny micropore of ultrafiltration membrane surface is only permitted
Xu Shui and small-molecule substance by and turn into permeate, and volume is then trapped within more than the material in film surface micropore footpath in stoste
The liquid feeding side of film, as concentrate, thus realization is to the purpose of the purification, separation and concentration of stoste.
Acidproof milipore filter group is entered by the acid waste water for being lifted, film can retain the macromolecular between 0.002-0.1 microns
Material and impurity, it is allowed to which small-molecule substance and soluble solid (inorganic salts) etc. pass through, while will the lower colloid of retention, albumen
Matter, microorganism and larger molecular organicses, the molecular weight cut off scope for representing milipore filter pore size are general 1,000-
Between 500,000, the operating pressure of milipore filter is generally 2-5bar.Enter by the product water of film and produce water tank, concentrated water flows into water inlet
Case is recycled.
Acidproof ultrafiltration is anisotropic membrane, and with finer and close top layer and the bottom based on finger, skin depth is
0.1 micron smaller, and the micropore with aligned orderly, and underlayer thickness is 200~250 microns, belongs to both surface filtration.PPSV is resistance to
Sour milipore filter is that membrane shell material is PVC, and core material is HDPE, and film layer uses PVDF materials, and acid resistance is greatly improved.It is new
Acidproof milipore filter-PPSV films have the following advantages that：
(1) traditional physico-chemical precipitation technique is substituted, reduces processing links, save space, investment cost and operating cost；
(2) more stable treatment effeciency is possessed, will not saturation, it is not necessary to change the easy saturation of such as quartz sand, activated carbon
Filler；
(3) filtration flow-rate is big, is two to three times of the flow velocity of other filter membranes, and high flow rate constantly washes away film surface, subtracts
Stop of the of low pollution thing on film surface；
(4) filter membrane can bear highly acid, alkalescence, bleach the cleaning with oxidating chemicals；
(5) membrane flux is big, and the permeable amount of 150LMH can be reached in a unit area；
(6) membrane tube has durable quality, and it has validity period more long compared with general filtering material.
Further, acidproof milipore filter group uses cleaning fluid wash cycles, and circulating pump is out of service during cleaning, concentrated water spout valve
Close, cleaning fluid enters from film group inlet, cleaning water tank is flowed into from the product mouth of a river after having cleaned.
Further, acidproof milipore filter group is backwashed using compressed air, and circulating pump is out of service during backwash, compression
Gas is backwashed from is produced from the mouth of a river into film product water side.
Wherein, a kind of acidproof ultra-filtration membrane device workflow is：
Acidproof ultra-filtration membrane device pump discharge valve 8, concentrated water valve 9 and product penstock 11 in normal operation are in and open shape
State.
Meanwhile, in order to ensure the flux of acidproof milipore filter group, film group needs to carry out regularly gas backwash and medicament circulation
Cleaning.
When gas is backwashed, close circulating pump 2, pump discharge valve 8, air bleeding valve 13 and produce penstock 11, open air intake valve
12, compressed air makes to be attached to the pollutant on film and comes off by surge tank 7 from the product water side flushing membrane of milipore filter.Gas recoils
The duration is washed for 15-20s, air bleeding valve 13 is opened after having recoiled, be then turned on circulating pump 2, pump discharge valve 8, the and of air bleeding valve 13
Penstock 11 is produced, film group is normally run.
Acidproof milipore filter is after 2-3 weeks are run, it is necessary to carry out a medicament cleaning.The water of cleaning agent carrys out self-produced water
Case, closes circulating pump 2, pump discharge valve 8, concentrated water valve 9 and produces penstock 11 during cleaning, start cleaning pump 6, valve 10 and valve
11, cleaning fluid flows into cleaning water tank, wash cycles 1 hour or so again after Chemical cleaning is carried out to film group.
By the acidproof ultra-filtration membrane device producing water ratios of PPSV up to 95%, device is produced acid waste water under normal operation
Water turbidity≤0.1NTU, SDI≤3, TSS≤1 ㎎/l.
Finally it should be noted that above example is only used to describe the technical solution of the utility model rather than to this technology
Method is limited, the utility model application can above extend to other modifications, change, using and embodiment, and because
This thinks all such modifications, change, using, embodiment all in the range of spirit or teaching of the present utility model.
