Refractory organic wastewater is firstly atomized by an atomizer and enters an electrochemical reactor, an electrode electrified with high-voltage and high-frequency current generates corona, high-energy electron radiation, ozone and ultraviolet light formed by discharge process cooperatively act on the atomized refractory organic wastewater, and the atomizer is combined with the electrochemical reactor to form a reactor for treating refractory organic wastewater through high-frequency and high-voltage discharge. The method disclosed by the invention is simple in structure, convenient to operate, high in efficiency, high in decomposition rate and free of secondary pollution.

Description

The method of high-frequency and high-voltage discharge process organic waste water and reactor thereof
Technical field
The present invention relates to sewage purification field, particularly relate to method and the reactor thereof of high-frequency and high-voltage discharge process organic wastewater with difficult degradation thereby.
Background technology
Along with industrial expansion, the industry inseparable with human lives is constantly risen, wherein most of industry can discharge more organic waste water in process of production, as trade effluents such as leather, papermaking, sugaring, weaving, printing and dyeing, agricultural chemicals, petrochemical compleies, high and the complicated component of these Industry Waste organic pollutants concentration, belongs to unmanageable trade effluent in sewage treatment process.
In recent years, the organic waste water of difficult for biological degradation causes great destruction to environment.The process of current organic waste water mainly adopts biologic treating technique, as conventional activated sludge process, biomembrance process.But for the organic waste water containing a large amount of recalcitrant substance, because the microorganism in biological treatment engineering receives serious restraining effect, have a strong impact on biodegradable effect.
The high-voltage pulse corona technology in addition of present utilization, high pressure pulse discharge and electrohydraulic effect is carried out in water, be grow up the fifties in last century, discharge in water is generally produced by sharp electrode in extremely uneven electric field, existing improved form and liquid electricity cavitation technique, pass into gas in the reactor, due to the shelf depreciation of bubble, add reactive behavior molecule, the subject matter of this discharge type is that treatment zone is limited, the erosion of electrode is comparatively serious, and work-ing life is shorter.
Summary of the invention
The object of this invention is to provide a kind of fast, the method for the high-frequency and high-voltage discharge process organic wastewater with difficult degradation thereby of efficient degradation organic waste water and reactor thereof.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of method of high-frequency and high-voltage discharge process organic waste water, electrochemical reactor is entered again after being first atomized by spraying gun by organic waste water, the electrode discharge being connected with oudin's current produces corona, the high energy electron irradiation formed by discharge process, ozone, UV-light three join same-action in the organic waste water of atomization, realize the degradation treatment to waste water.
In technique scheme, electrochemical reactor is box electrochemical reactor, and reactor is generally rectangle, and has different three-dimensional dimensions, has two cube electrodes, has water-in and water outlet.
Before electrochemical reactor, add spraying gun, organic wastewater with difficult degradation thereby can be made to be atomized, its specific surface area is increased, reacts completely when reacting in electrochemical reactor and improve speed.
A kind of reactor of high-frequency and high-voltage discharge process organic waste water, comprise reaction chamber, be arranged on the battery lead plate of described reaction chamber outer bottom, described battery lead plate is electrically connected with ground terminal, run through in described reaction chamber and be provided with silica tube, described silica tube one end insulation and obturation, the other end passes into electrode cable, described electrode cable is connected with high-frequency and high-voltage power supply, described reaction chamber two ends are provided with inlet mouth, air outlet, and described inlet mouth is communicated with spraying gun, and described spraying gun is provided with water-in.
In technique scheme, discharged by high-frequency and high-voltage, make ionization of air in reaction chamber produce corona, form high energy electron irradiation, ozone, UV-light by discharge process.After the organic wastewater with difficult degradation thereby after being atomized device atomization enters reaction chamber, it is subject to the combined action of high energy electron irradiation, ozone oxidation, UV-light decomposition.Reaction is rapidly efficient.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1, present invention employs spraying gun organic waste water is atomized in advance, increase the specific surface area of organic waste water, can sufficient reacting, improve reaction efficiency;
2, the present invention utilizes high energy electron irradiation, ozone oxidation and UV-light to decompose coupling technique, can decomposing organic matter quickly and efficiently;
3, present device is simple, easy to operate, process range wide and non-secondary pollution.
Accompanying drawing explanation
Fig. 1 is the sectional view of high-frequency and high-voltage discharge process organic wastewater with difficult degradation thereby reactor.
Wherein: 1, reaction chamber; 2, battery lead plate; 3, ground terminal; 4, silica tube; 5, electrode cable; 6, high-frequency high-voltage source; 7, inlet mouth; 8, air outlet; 9, spraying gun; 10 water-ins.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one:
As shown in Figure 1, high-frequency and high-voltage discharge process organic wastewater with difficult degradation thereby reactor, comprise reaction chamber 1, be arranged on the battery lead plate 2 of reaction chamber 1 outer bottom, battery lead plate 2 is connected with ground terminal 3, in reaction chamber 1, runs through being provided with silica tube 4, silica tube 4 one end insulation and obturation, the other end passes into electrode cable 5, and electrode cable 5 is connected with high-frequency high-voltage source 6, and reaction chamber 1 two ends are provided with inlet mouth 7, air outlet 8, inlet mouth 7 is communicated with spraying gun 9, and spraying gun 9 is provided with water-in 10.
Before reaction chamber 1, add spraying gun 9, organic wastewater with difficult degradation thereby can be made to be atomized, its specific surface area is increased, reacts completely and improve speed.
The electric current that high-frequency high-voltage source 6 passes into 40KHz, 10KV makes to produce corona to atmospherical discharges in reaction chamber 1, produces electronics, atom, molecule and the free radical with high activity, as H, OH, H 3o +, O 2, O 3, Sauerstoffatom, hydrogen atom, hydroxyl radical free radical, the H be under different excited state 2photon, electronics etc.
Its reaction equation is as follows:
O 3+OH -→HO 2 -+2O·
HO 2 -+H +→H 2O 2
O 3+ HO 2 -→·OH+ O 2 -+ O 2
