Plasma is the 4th state of material, and plasma, which directly removes NOx, mainly two kinds of approach：One kind is to decompose way
Footpath, i.e. electronics and N2Collision produces N atoms, and then N atoms make NO be converted into N by reaction2.Another kind is oxidative pathway, that is, is existed
NO is oxidized to NO under action of plasma2, then with H2The OH Free Radicals that O electric discharges produce are finally with nitric acid or Asia
The forms such as nitrate remove NO.Plasma directly removes VOCs and relies primarily on substantial amounts of chemically active species, including high energy
Electronics, ion, excited state molecule and free radical etc., the energy of these active species are higher than the bond energy of gas molecule, they and
Frequently collision occurs for VOCs molecules, makes molecule that scission of link dissociation occur and VOCs degrades.In addition, when aerobic presence in reaction
When, oxygen molecule produces oxygen atom and the oxygen molecule of excitation state, these strong oxidizing properties with the high energy electron collision in plasma
Particle react with VOCs molecules, so as to be nontoxic CO by VOCs molecular oxidations2。H2O can be produced under argon-arc plasma field effect

When light radiation is irradiated, the electronics in valence band is excited, and crosses forbidden band and enters conduction band, while corresponding hole is produced in valence band.
The diverse location of particle surface is arrived in electronics and hole migration, and hole has very strong electronic capability in itself, can capture NOx and
Electronics in VOCs systems, makes it be activated and aoxidize.Electronics and the oxygen reaction generation oxidability in water and air are stronger
OH and O2 OneDeng being that NOx and VOCs are finally aoxidized to generation NO3 One、CO2And H2The most important oxidant of O.

Fe2++H2O2→Fe3++OH—+·OH
Fe2++·OH→Fe3++OH—
·OH+H2O2→·HO2+H2O
The DSA anodes arranged in liquid phase oxidation tower, occur electrochemical reaction after energization, and H is produced under the conditions of waterfall gas2O2。
Iron-carbon micro-electrolysis technology mainly make use of the reproducibility of iron, the electrochemistry of iron, the flocculation adsorption three of iron ion
Collective effect purifies waste water.
Iron-carbon micro-electrolysis electrochemical reaction process is as follows：
Anode:Fe-2e→Fe2+E (Fe/Fe2+)=0.44V
Cathode:2H++2e→H2E (H+/H2)=0.00V
The Fe of the nascent state of generation2+With atom H, they have high chemism, can change many organic matters in waste water
Structure and characteristic, make organic matter that the effect such as chain rupture, open loop occur.
If there is waterfall gas, it also occur that following reaction：
O2+4H++4e→2H2O E (O2)=1.23V
O2+2H2O+4e→4OH— E(O2/OH—)=0.41V
Fe2++O2+4H+→2H2O+Fe3+
The OH of generation—The reason for being the rise of water outlet pH value, and by Fe2+Aoxidize the Fe of generation3+The gradually hydrolysis generation degree of polymerization
Big Fe (OH)3Colloid flocculant, can effectively adsorb, agglomerate suspended matter and heavy metal ion in water, so as to strengthen pair
The clean-up effect of waste water, the Fe produced similar to Fenton reagent3+The mechanism of action.
The DSA anodes of No. three electrode groups of liquid phase oxidation tower and No. four electrode groups are titanium-based series metal oxide anode (Ti/
IrO2/IrO2-SnO2), being capable of efficient catalytic Strong oxdiative thing ClO—And the generation of OH.
The cathode of No. three electrode groups of liquid phase oxidation tower and No. four electrode groups is platinum cathode (Pt), Cu-Zn alloys or Ti, right
NO3 —The also original very high efficiency of catalysis, electrolysis performance stablizes, and electrode life is grown.
CODcr, SO in liquid phase oxidation tower waste water3 2—With nitrogen-containing pollutant (mainly in the form of two kinds of ammoniacal nitrogen and nitrate nitrogen
In the presence of), using the ringing of circulating pump, the No.1 electrolytic cell through gaseous oxidation tower, No. two electrolytic cells and liquid phase oxidation tower
Circulation electrochemical couple oxidation-flocculation of No. three electrolytic cells, and the final control of through liquid phase oxidation tower No. four electrolytic cells
Property disposal, using electric tank cathode by the nitrate in waste water, nitrate reductase into NO2 —、NH4 +、OH—And N2；Utilize DSA
Anode region generation oxidizing species ClO—And OH, by CODcr, SO in waste water3 2—、NH4 +、NO2 —It is oxidized to SO4 2—、
Cl—、NO3 —And N2、CO2, reach the target of purification of waste water；A certain amount of Cl is added in waste water—, ClO can be promoted—Generation.
Since multilayer Fe-C micro-electrolysis stuffings, the washing of shower water, the air-flow of gaseous oxidation tower repeatedly collect baffling, filler
