The catalytic microelectrolysis device is simple in structure and convenient to operate, and adopts a layered filling and internal circulation method, so that fillers have low possibility of hardening and inactivating. Meanwhile, through the adoption of aeration and internal circulation, the reaction rate is improved, the recovery capability is enhanced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of sewage pre-treatment device, especially a kind of micro-electrolysis device, a kind of catalytic microelectrolyzer specifically.
Background technology
At present, micro-electrolysis process has mainly utilized the reductibility of iron, the electrochemistry of iron, the flocculation absorption three acting in conjunction of iron ion to purify liquid waste.
Its handling principle is under acidic conditions, and during filler when waste water by iron content and charcoal, iron becomes anode, and carbon becomes negative electrode, and micro-current flowing is arranged, and forms numerous small battery, and the organism in waste water is reduced oxidation under the effect of micro-electric current.This reaction in the situation that acid and oxygenation corrosion the most very and there is the function be proved as follows: the reduction reaction due to organism participation negative electrode, make functional group that variation occur, changed former organic character, reduced colourity, improved the B/C value; Some inorganicss also participate in reaction generation precipitation and are removed, as: Fe2++ S2-=FeS.
Colloidal particle in waste water and small dispersion pollutent are subject to electric field action, produce electrophoresis, move to the electrode of opposite charges, and are gathered on electrode and make clarification of water; The Fe2+ of anode nascent state has extremely strong adsorptive power with generation Fe (OH) 2, Fe (OH) 3 in lime, and water is clarified; The hydrogen that anode generates, have reductibility, and the toxicity that reduces waste water increases the oxidizability of waste water, is beneficial to the subsequent oxidation method and processes the raising effect.
Micro-electrolysis process, since being born, just having caused domestic and international environmental protection researcher's concern, and has been put to rapidly the application of sewage treatment industry.Domestic and international micro-electrolyzer is all fixed beds at present, is characterized in simple in structure, pushes away good fluidity, but has many practicality problems: the one, and efficiency is not high, and speed of response is unhappy; The 2nd, filler in use for some time, thereby easily by impurity parcel in sewage, caused a body to harden, the filler passivation, form short circuit and dead band; The 3rd, it is large that iron filings supplement labour intensity.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can overcomes the problems referred to above, can accelerate speed of reaction, the technical scheme of intensified response effect.
The technical solution of the utility model is:
A kind of catalytic microelectrolyzer, comprise cylindrical tower body, and its bottom is provided with conical mud-removing bucket, and top is provided with the tank that overflows be connected with water outlet.Also be provided with 3 layers from bottom to top in tower body inside for stacking the stuffing frame of filler, and be provided with the water distributor be connected with water-in and the aeration tube be connected with inlet mouth below lower floor's stuffing frame.
Be provided with the internal recycle header below the stuffing frame of upper strata, and, after the inner circulating tube that impeller pump is housed through the tower body outside, be connected with the outlet of tower body bottom mud-removing bucket.
Between lower floor and middle filler frame, and, on the tower body wall between middle level and upper strata stuffing frame, respectively be provided with a manhole, can pass in and out that tower body is overhauled and additional fillers for the workman.
The beneficial effects of the utility model:
The utility model is simple in structure, easy to operate, adopts layering filler and internal circulation method, makes filler be difficult for hardening and passivation.Simultaneously, by aeration and internal recycle, can improve speed of reaction, strengthen restorability, improving production efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model comprises cylindrical tower body 2, and its bottom is provided with conical mud-removing bucket 14, top be provided with water outlet 8, be connected overflow tank 1.Also be provided with 3 layers of stuffing frame 10 from bottom to top in tower body 2 inside, on every layer of stuffing frame 10, heap has filler 9.Be provided with the water distributor 13 be connected with water-in 12 and the aeration tube 5 be connected with inlet mouth 6 below lower floor's stuffing frame.Be provided with internal recycle header 3 below the stuffing frame of upper strata, and, after the inner circulating tube 4 that impeller pump 7 is housed through tower body 1 outside, be connected with the outlet 15 of tower body 1 bottom mud-removing bucket 14.Between lower floor and middle filler frame, and, on the tower body wall between middle level and upper strata stuffing frame, also respectively be provided with a manhole 11, can pass in and out that tower body is overhauled and additional fillers for the workman.
Operation scheme of the present utility model is: waste water pumps into tower body 1 by water-in 12 after PH regulates, and opens aerating apparatus and internal circulation apparatus simultaneously.Waste water from lower to upper, after the electrolytic reaction of 3 layers of filler, flows out through water outlet 8 from overflowing tank 1.If the harden situation of fouling of filler continuously or after longer for some time of intermittent operation, may appear in system, reaction efficiency is reduced.At this time open internal circulation apparatus, the water that extracts 14 ends of mud-removing bucket by impeller pump 7 is transported to top internal recycle header 3 and discharges, and realizes that the acceleration of water body in tower circulates, and strengthens the backwash rate to filler 9, and the situation of the fouling that makes to harden is effectively alleviated.Under aeration and internal recycle effect, micro-electrolysis reaction speed is multiplied than traditional technology, and reaction effect is certain amplitude and rises.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
