Description

Electrode couples ozone oxidation integral reactor
Technical field
The present invention relates to a kind of sewage-treatment plant, more particularly to one kind is by electrode technology and ozonation technology coupling Manage the reactor of sewage.
Background technology
Ozonation technology is widely applied in water treatment field, such as sterilizing, the industrial wastewater of city water Advanced treating etc..The current technology is subject to more and more in organic wastewater particularly difficult for biological degradation method for processing organic wastewater Attention.But due to its oxidation selectivity, ozone utilization rate is low, operating cost is high the problems such as, the popularization of ozonation technology should With severely limited.Ozone directly can decompose oxidation operation as a kind of strong oxidizer, but it is anti-with organic matter There should be stronger selectivity, larger molecular organicses are changed into small organic molecule in can only often making waste water, produce hydroxyl certainly Efficiency by base is relatively low.
Electrochemical method administers waste water and need not typically add oxidant, and equipment is simple, small volume, and sludge quantity is few, post processing Simply, the commonly known as green oxidation technology of " environment-friendly ".Meanwhile, traditional three-dimensional electrode reactor treatment difficult for biological degradation Organic wastewater, most electrochemical degradations to carry out organic wastewater under simple DC Electric Field, therefore organic dirt in waste water Conversion and the removal efficiency for contaminating thing be not high, it is impossible to realizes the conversion of useless Organic substance in water.
The combination of ozonation technology and electrode technology can improve water treatment effect, but prior art is simple Electrolysis is combined with ozone oxidation, treatment effeciency is low, high cost.Such as the Chinese patent application of Application No. 201510816139.8 " a kind of wastewater treatment equipment and by the device process waste water method ", including ozone generator, 3 D electrode reactor and D.C. regulated power supply, wherein ozone gas distribution collet is provided with the 3 D electrode reactor, under the ozone gas distribution collet Side is provided with ozonation aerated head, granule electrode, main electrode is provided with above the ozonation aerated head, in the 3 D electrode reactor Cavity wall on insertion be provided with waste liquid charging aperture and sample tap.The technical scheme is directly passed through ozone in electrode reactor, Treatment effeciency to waste water is low, it is impossible to give full play to each self-applying, there is uncertain interference.
Such as " a kind of catalytic ozonation is combined the Chinese patent application of Application No. 201610051298.8 with Electro Sorb Coking advanced waste treatment system ", the system includes catalytic ozonation reactor, ozone generator, oxygen tank, gas-liquid separation Device, filter, electric adsorption device, reuse water tank, concentrated water case, product water solenoid valve, concentrated water magnetic valve and connecting pipe;Its In, by the water inlet of the outlet after biochemical treatment and through the coking chemical waste water after coagulating sedimentation and the catalytic ozonation reactor Mouth connection;The delivery port of the catalytic ozonation reactor is connected with gas-liquid separation device;The gas-liquid separation device goes out The mouth of a river is connected with the water inlet of filter;Described filter delivery port is connected with the water inlet of electric adsorption device, Electro Sorb dress The delivery port put is connected by producing water solenoid valve with reuse water tank, while being connected with concentrated water case by concentrated water magnetic valve.The technology Catalytic ozonation reactor and electric adsorption device are simple cascade in scheme, each can only successively be played a role, not Have and play real synergy, thus the shortcoming existed when each individually processing can not be overcome.
If the Chinese invention patent of Patent No. 201310236853.0 is " at a kind of ozone tail gas reinforcing ozone oxidation waste water The method and device of reason ", the processing unit includes the preelectrolysis unit and ozone oxidation unit of connection, the ozone oxidation unit Offgas outlet be connected into preelectrolysis unit.The method makes waste water initially enter preelectrolysis unit carries out cell reaction, cell reaction Waste water afterwards flows into ozone oxidation unit, and being passed through ozone in ozone oxidation unit is reacted, what ozone oxidation unit was produced Ozone tail gas are aerated in accessing preelectrolysis unit.The technical scheme is same what preelectrolysis unit and ozone oxidation unit were connected When, and ozone tail gas are passed through preelectrolysis unit, but preelectrolysis unit and ozone oxidation unit are still each other two relatively independent Device, thus equipment cost is high.
