Description

The device and method for making its electrode of food and drink waste water are handled with oxygen cathode Fenton
Technical field
The present invention relates to wastewater treatment and electrode fabrication technical field, more particularly to a kind of oxygen cathode Fenton processing meal Drink waste plant and method for making its electrode.
Background technology
Research and application of the world today on high-level oxidation technology, mainly there is ozone catalytic technology, Fenton reagent oxygen Change technology(Including all kinds of combination techniques using Fenton reactions as core or deriving technology), sonication techniques, electrochemistry oxygen Change technology, Wet Oxidation Process, supercritical water technology and photocatalysis technology/photo-electrocatalytic technology etc..
Fenton reagent reaction was found first by French scientist H.J.H. Fenton in 1894.Typically Fenton reagent is through adding ferrous ion(Symbol Fe is used below2+Instead of)By Fe2+Catalysis reduction hydrogen peroxide(Use below Symbol H2O2Instead of), occur Fenton chemical reactions and produce hydroxyl radical free radical(OH is designated as below), so as to trigger OH to having The chain type oxidative degradation of organic pollutants.
H2O2 + Fe2+→·OH + Fe+3 (1)
And each pollutant in different types of waste water is produced using the powerful oxidabilities of the OH of reaction generation The concentration for lowering pollutant is realized in the physical-chemical effect such as degraded, destruction, oxidation, and partial contamination thing can ultimately generate nontoxic Or the micromolecular compound of low toxicity, or even degrade to CO2、H2O、O2、NO-2、NO-3、N2、PO4 -3、S、SO3 -2、SO4 -2Etc. Non-toxic Compound ".
University On The Mountain Of Swallows scholar Song is beautiful, Ma Yue, Li Zheng and Shandong University horse are mutually as respectively in its master, thesis for the doctorate[1-4]In detail Carefully discussing use, " the efficient PTFE negative electrodes of acetylene black one prepare hydrogen peroxide and produced by adding ferrous ion or in-situ electrolysis Raw Fe2+.And then occur Fenton reactions.Different types of oxygen cathode, Ni―Ti anode electrode design are also relates in paper and is adopted H is produced with DC voltage electrolysis2O2And Fe2+.The main contributions of above-mentioned paper are:Produced using novel oxygen cathode technology of preparing Substantial amounts of H2O2And synchronously produce Fe using iron anode2+, eliminate added regent H2O2And Fe2+, processing cost is reduced, is also solved Determined H2O2Transport and storage safety problem.
Tianjin Institute of Industrial Biotechnology, Chinese Accademy of Sciences Li Chen etc. is in a kind of patent publication No. 104496003A " hydroxyls Free radical efficiently produces application apparatus and its application method " in propose it is a kind of produce hydroxyl radical free radical device and user Method.The guide shell of a both ends open is set in shell inner sleeve, and air inlet pipe is set in guide shell bottom, the liquid of reaction is added Submerged into shell, and by guide shell, air is inwardly persistently injected by air inlet pipe, then the gas run up is produced in guide shell Stream, liquid drives down by air-flow and also run up inside guide shell, after running at the top of guide shell, under gravity to Guide shell periphery is scattered and runs downwards, and reaches the outer casing bottom again, so that liquid formation is by inside guide shell And the internal circulation system between guide shell side wall and side wall of outer shell, the catalyst in liquid is fully contacted with battery lead plate, produce Substantial amounts of hydroxyl radical free radical, and the hydroxyl radical free radical of generation is contacted in time with the reaction material in liquid, it is to avoid hydroxyl is certainly Failure is caused in the accumulative of part by base, the utilization ratio of hydroxyl radical free radical can be effectively improved.
But, prior art has the following disadvantages:
(1), above-mentioned " prepared by the efficient PTFE negative electrodes of acetylene black one " is the small-sized preparation in laboratory, is not produced in batches more There is no commodity production.Prepared by broad-area electrode have certain technical bottleneck influence further to improve H2O2Yield.The electrode prepared at present Specific surface area influence electrode performance less than normal.
(2), DC voltage synchronously produces H2O2The amount of sum can not be reacted with Fenton needed for flux matched, often Fe2+Amount It is far longer than the required amount of reaction, causes to consume the OH produced, influences treatment effect.
(3), the electrolytic efficiency of DC voltage electrolysis is relatively low, and is also easy to produce electrode passivation.Although can be using pole(It is i.e. cloudy Anode is exchanged)Method mitigate passivation phenomenon.But due to anode and cathode material used, structure and differ, not only increase electrode system Standby expense, and effect is not obvious.
(4), because using surely potential electrolysis is flowed anyhow, current efficiency is relatively low.Electric current is imitated particularly under larger current density Rate lowers obvious.
(5), because food and drink waste water is higher containing grease, the substantial amounts of oil droplet independently of aqueous phase there is in waste water.Have a strong impact on OH is acted on the grease inside oil droplet, makes reaction slack-off and effect is incomplete, influence treatment effect.
(6), publication number 104496003A patent proposes a kind of hydrodynamics scheme, makes reactiveness more reasonable.But Do not solve in itself above-mentioned(5)In the problem of mention, do not solved thoroughly for essential problem.
