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
Technical field
The present invention relates to the sewage purification field, relate in particular 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 the human lives constantly risen, wherein most of industry can be discharged more organic waste water in process of production, as trade effluents such as leather, papermaking, sugaring, weaving, printing and dyeing, agricultural chemicals, petrochemical compleies, organic contamination substrate concentration height and complicated component in these trade effluents belong to unmanageable trade effluent in sewage treatment process.
In recent years, the organic waste water of difficult for biological degradation has caused great destruction to environment.The processing of current organic waste water mainly is to adopt biologic treating technique, as activated sludge process, biomembrance process commonly used.But for the organic waste water that contains a large amount of recalcitrant substances, because the microorganism in the biological treatment engineering has been subjected to serious restraining effect, had a strong impact on biodegradable effect.
The high-voltage pulse corona technology of using now in addition, carrying out high pressure pulse discharge in water is electrohydraulic effect, be to grow up the fifties in last century, discharge in water is generally produced by sharp electrode in extremely inhomogeneous electric field, and existing improved form is liquid electricity cavitation technique, in reactor, feed gas, because the shelf depreciation of bubble has increased the 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 purpose of this invention is to provide a kind of fast, method and the reactor thereof of the high-frequency and high-voltage discharge process organic wastewater with difficult degradation thereby of efficient degradation organic waste water.
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, organic waste water is entered electrochemical reactor afterwards again by the spraying gun atomizing earlier, the electrode discharge that is connected with oudin's current produces corona, the high energy electron irradiation, ozone, the UV-light three that are formed by discharge process join same-action in the organic waste water of atomizing, realize the degradation treatment to waste water.
In the technique scheme, electrochemical reactor is box electrochemical reactor, and reactor generally is rectangle, and has different three-dimensional dimensions, and two cube electrodes are arranged, and has water-in and water outlet.
Before electrochemical reactor, add spraying gun, can make the organic wastewater with difficult degradation thereby atomizing, its specific surface area is increased, react completely and raising speed when in electrochemical reactor, reacting.
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, be electrically connected with ground terminal on the described battery lead plate, run through being provided with silica tube in the described reaction chamber, described silica tube one end insulation sealing, the other end feeds 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 the technique scheme, by the high-frequency and high-voltage discharge, make ionization of air generation corona in the reaction chamber, form high energy electron irradiation, ozone, UV-light by discharge process.After organic wastewater with difficult degradation thereby after being atomized the device atomizing entered reaction chamber, it was subjected 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 advantage:
1, the present invention has adopted spraying gun with organic waste water atomizing in advance, has increased the specific surface area of organic waste water, can reach sufficient reacting, improves reaction efficiency;
2, the present invention utilizes high energy electron irradiation, ozone oxidation and UV-light to decompose coupling technique, decomposing organic matter quickly and efficiently;
3, present device is simple, easy to operate, process range wide and non-secondary pollution.
