The principle of work of the ultrasonic Fenton oxidation combination treatment of the utility model sewage apparatus:
There are some reports in Fenton reactor past in sewage disposal, adds exactly Fe
2sO
4and H
2o
2, hydrogen peroxide (H

2) and ferrous ion Fe
2+mixing solutions there is strong oxidizing property, a lot of known organic compound at that time can be oxidized to inorganic states as carboxylic acid, alcohol, ester class, oxidation effectiveness is fairly obvious, the combination of ferrous salt and hydrogen peroxide is called Fenton reagent, it can remove the hardly degraded organic substance that traditional wastewater processing technology cannot be removed by the efficient oxidation, its essence is H
2o
2at Fe
2+katalysis under generate and there is the hydroxyl radical free radical (OH) of high reaction activity, OH can make its degraded with most of organism effects.
Ultrasonic wave be frequency higher than 20kHz, and do not cause the elastic wave of the sense of hearing.Hyperacoustic cavitation effect, heat effect and mechanical effect are that ultrasonic technique is for accelerating three broad theory foundations of medicinal liquor brew process.(1) cavatition.In liquid, often have small bubbles some vacuum or that contain a small amount of gas or steam, these small bubbles sizes differ.When the ul-trasonic irradiation of certain frequency is during in liquid, only have the vesicle that size is suitable that resonance effect can occur, the vesicle that is greater than resonant size is displaced outside liquid, and the vesicle that is less than resonant size becomes gradually large under ultrasonication.While approaching resonant size, the sparse stage of sound wave swells rapidly vesicle, and at the compression stage of sound wave, vesicle is insulated compression suddenly again, until bury in oblivion.Bury in oblivion in process, vesicle inside can reach high temperature and several thousand atmospheric high pressure of several thousand degree.Above-mentioned phenomenon is called cavitation phenomenon.In the time that vesicle swells, because friction can produce electric charge, can produce electric discharge, luminescence phenomenon burying in oblivion in process.Ultrasonic wave can make the chemical reaction that normal temperature and pressure can not occur occur under cavatition, can make the cell rupture of mud, accelerate decomposition.(2) heat effect.Ultrasonic wave is propagated in medium, and its vibrational energy is constantly absorbed and changes heat energy into and self temperature is raise by medium.Acoustic energy is absorbed the entirety heating that can cause in medium, the local heating at wavefront place the etc. when local heating outside border and cavitation form shock wave.Hyperacoustic intensity is larger, and the heat effect of generation is stronger.The heats of this part can be accelerated the dissolving of effective ingredient in medicinal material.(3) mechanical effect.Ultrasonic wave is the propagation of mechanical vibrational energy, can in liquid, form and effectively stirs and flow, and destroys the structure of medium, pulverizes the particle in liquid, can reach common Low-Frequency Mechanical and stir the effect not reaching.This mechanical agitation can make strength of fluid diffusion, accelerates effective ingredient and leaches.In addition, also find that ultrasonic wave can activate the plysiochemical process of some enzyme and cell participation, improves enzyme and accelerates cell metabolism procedure.In ultrasonic procedure, produce and break the micro-bubble that oscillating pressure generates and the mechanical vibration mechanism producing, this vibration has the cellularstructure of destruction and anabolic action.Can attenuate because the effect such as tangential force and microjet of ultrasonic vibration makes solid phase particles or plate fragmentation to heterogeneous interface, thereby can play the effect taking out stains, ultrasonic have a very strong sterilization fresh-keeping effect.
The principle in aeration oxidation pond, settling pond and biological degradation pond is on the books at a lot of open source literatures, herein not as mainly introducing.
The beneficial effects of the utility model:
The equipment of the ultrasonic Fenton oxidation combination treatment of the utility model sewage has adopted Fenton's reaction and ultrasonication to add acid-alkali accommodation, aeration, oxidation, clarify and decolorize and biological degradation comprehensive treating process, make waste water after treatment not only reach emission standard, can also be for the production of process.
