Sterilized filtering cup provided by the utility model is that water flow is made to filter electrochemistry oxygen out of electrode interior passes through electrode
Change structure, reaction efficiency can be improved, reduces energy consumption, the service life of electrode is improved, using porous conductive material as interior mistake
Filter formula electrode with the contact probability and area of enhancement microbiological and electrode surface, can then improve the mass transfer of disinfecting system and straight
Oxidation sterilizing ability is connect, the efficient inactivation and organic matter drop of microorganism can be realized under low-voltage (voltage of power supply is 1-5V)
Solution increases convection current (microorganism contacts electrode, reaction product concentration gradient) using this method, than " flat flow " for mass transfer
" stirring-type " increases.
The voltage of power supply is 1-5V, preferably 2-3V, and power supply can choose button cell or battery.
Electrochemistry essentially consists in the oxidation of anode to organic matter degradation and bacteria inactivation rate, when irrigating gate is water outlet
When, it is preferable that porous cathode, porous electrode interlayer and porous anode are set gradually from top to bottom, connect water elder generation Contact cathod again
Anode is touched, by the way of this anode postposition, the removal rate of Organic substance in water is higher by least compared to the mode of cathode postposition
30-40%, so the mode of preferred anodes postposition.
When anodic-cathodic surface is electrochemically reacted, most commonly H+And OH-Accumulation, can seriously inhibit react into
Row, it is leading disinfection mechanism that the mode of anode postposition, which is based on anodic oxidation (its contribution accounts for 70% or more), when water flow passes through
When electrode filter membrane, water flow first contacts the cathode of electrode filter membrane, and electrode reaction occurs, and generates hydroxide ion, solution ph
It increases, the microorganism in water flow is negatively charged, to make microorganism be easier to contact anode, when water flow contacts anode again, in water
Microorganism and positive contact lose electronics, be oxidized, to be killed, and the H that anode generates+Preposition cathode can be neutralized
The OH of generation-, further promote anode reaction, realize more low-voltage, microorganism efficient inactivation and organic matter under the low residence time
Rapid degradation, while reducing the generation of disinfection by-products (Active Chlorine by-product), reduce energy consumption.Meanwhile when electricity occurs for cathode
Pole reaction generates peroxide hydrogen radical (HO2 -) when, since peroxide hydrogen radical has stronger oxidisability, can go out to microorganism direct oxidation
It is living, the degree of microbiological oxidation inactivation is further increased, realizes efficient inactivation.
After the flow rate of water flow of electrode filtering film process becomes larger, the hydroxide ion cumulative effect of cathode is lower, after losing
The advantage of anode is set, Disinfection Effect in parallel is poor, in order to solve this problem, it is preferable that electrode filter membrane is matched using more cathodes
The assembled unit form of single anode, after multilayer cathode is handled, the strong basicity treatment fluid of generation will flow into anode, and microorganism exists
Direct oxidation effect easily occurs under alkaline condition, can realize microorganism complete inactivation, this assembled unit setting at low voltage
Mode is obviously improved unit disinfecting power, greatly shortens the hydraulic detention time of unit, also can effectively avoid microorganism
Excessive oxidation or it is broken caused by energy dissipation and subsequent competition the problem of sterilizing site.
