Change rate, reduces the oxidation activation energy of initial reactant, the effect for handling water outlet is preferable；But its reaction temperature is 20-150
DEG C, waste water still needs to be preheated, and is coupled using two-dimentional electro-catalysis with wet oxidation, and electro-catalysis efficiency is lower, electrolysis processing
Time is 1-7h, is consumed energy higher.Application No. is 99110084.0 Chinese patents to disclose a kind of " electric ally caltalytic contact oxidizing work
Skill ", using titanium dioxide or vanadic anhydride as catalyst, oxygen is as oxidant, applied voltage range 5-50V, reaction temperature
At 0-40 DEG C, dyeing waste water can be handled and reach national secondary discharge standard, reaction condition is milder, but its limit waste water into
Water COD is in 2000mg/L hereinafter, the treatment effect for high concentrated organic wastewater is bad, and energy consumption is larger.
Although the above-mentioned a variety of high-level oxidation technologies of coupling can guarantee to maintain higher processing under mild reaction conditions
Efficiency, but thus cause high energy consumption operation problem and not can avoid still.If fuel cell principle can be utilized, so that reactor itself
Sewage treatment in situ is produced electricity and carried out, this problem can be solved.Microbiological fuel cell (MFC) is newly old using microorganism
The biomass energy of metabolism is converted into fuel cell by electrochemical techniques, has extensive development empty in water treatment field
Between, it can be achieved at the same time sewage treatment and save energy consumption.However, compared with normal power supplies, the electricity production function of microbiological fuel cell
Rate and electricity production quality are lower, so how improving it and producing electricity power and efficiently use electric energy is the key that restrict technology development
Problem.Disclose application No. is 201510436047.7 Chinese patent " a kind of device for handling organic wastewater with difficult degradation thereby and its
Photoelectrocatalysioxidization oxidization is effectively cooperated and is connect with two-stage MFC using photoelectrocatalysioxidization oxidization in conjunction with MFC technology by purposes ", real
The existing water route two-stage MFC series connection but circuit independence.But it uses two-stage MFC to connect, and easily leads to second level MFC carbon source deficiency, multistage string
Join the problems such as internal mass transfer resistance increases；In addition, two-stage MFC is respectively independent to be mentioned to photocatalysis apparatus respectively in circuit arrangement
For bias, the stability of power supply is ensured, but can not be utilization in situ by producing electricity, so utilization rate of electrical is lower, cause not
Necessary energy loss.
In addition, it is exactly the low problem of oxidant utilization that catalytic wet oxidation technology industrialization, which faces another hang-up,
It is mainly related with plenum system.Common plenum system be usually gas be aerated by fixed bed bottom or pressure air-dissolving enter
Into waste water.The mode of bottom aeration supplies, and contact of the gaseous oxidizing agent with solid-phase catalyst is ineffective, and generates bubble
Larger to be easy to cause gas absorption in catalyst surface, the contact to waste water with solid-phase catalyst causes to hinder to a certain extent,
The catalysis oxidation efficiency is low；Meanwhile the aeration quantity of bottom aeration is generally large, easily causes the disturbance of catalyst granules and water body, leads
It causes catalyst granules mutually to collide, the effective catalyst component of catalyst surface occurs and fall off the phenomenon that being lost.The gas supply of pressure air-dissolving
Mode, be gas is carried out pressurizeing before waste water enters reactor it is soluble in water, then by gas-liquid mixture by reactor,
Organic pollutant under the action of solid-phase catalyst, in catalyzing oxidizing degrading water；This kind of plenum system needs reactor one
It works under fixed pressure condition, and as gaseous oxidizing agent constantly consumes, the waste water dissolution of inside reactor different location
Gas concentration is different, and catalytic oxidation effect is unstable.
