In order to eliminate oxychlorination agent and oxidized byproduct residual in the treating water, in activated carbon filtration groove 8, added gac, in activated carbon filtration groove 8, after the last final treating water of handling flow into the groove of releasing (accompanying drawing does not indicate), finally discharge in the ocean 10.
Electrolytic oxidation principle to ozonize stage (S54) and electrolysis treatment stage (S58) is described in detail now.
Intramolecular pair of key of the hard-decomposed organic matter that contains in the sewage had the ozone of strong oxidizing property to be attacked, and makes it connect disconnection, becomes decomposable organic substance.
The decomposition course of ozonize is as follows:
O
2+ high pressure → O
3
O
3+ organism → oxidized byproduct+H
2O+CO

In the catalytic mixing device, the decomposable pollution substance that exists in the mixing water after itself and the sea water mixing can be eliminated by direct oxidation or indirect oxidation through the sewage after the ozonize.In the direct oxidation process, pollution substance gathers at anode disc, and the exchange by electronics is eliminated.Indirect oxidation is by electrolytic electrochemistry, utilizes the similar hypochlorous strong oxidizer that produces, the pollution substance in the oxidation mixing water.Owing to contain abundant ionogen in the seawater, direct oxidation with utilize the indirect oxidation of oxychlorination agent to carry out apace, so just can obtain good oxidation effectiveness in the short period of time.This electrolytic process, in the oxidation mixing water, have organic substance in, not only pollution substances such as nitrogen can be completely oxidized to stable material and with its removal, and by directly and the indirect oxidation process can destroy intestinal bacteria and pathogenic bacteria.
Owing to above reason, utilization of the present invention contains the seawater of a large amount of chlorions as catalyzer, and the electrolytic process of chlorine is as follows:
Anode: 2Cl
-→ Cl
2(dissolving)+2e
-
Negative electrode: 2H
2O+2e
-→ 2OH
-+ H
2
Electrode plate reaction: Cl
2+ H
2O → HOCl+Cl
-+ H

HOCl→OCl
-+H

Anode produces hypochlorous acid (HOCl), and negative electrode produces hypochlorite (OCl
-), such intermediate product produces the indirect oxidation reaction with organic substance in water.Secondly, observation is eliminated organic process by electrolysis and can be known that electrolytic solution is oxidized to floating state by steady state in the electric decomposition course of acidic solution metal ion, and producing intermediate material is reactant.
At anode, the oxidized generation carbonic acid gas of a large amount of organism is diffused in the solution, and reaction formula is as follows:
xM
n+→xM
(n+1)++xe

(n+1)++ reagent (reacting agent) → xM

Though the electrolysis of organic substance is in anodic oxidation, but the time its process be divided into two kinds, a kind of is that the hydroxide radical that produces behind the brine electrolysis is attached to the electrode plate surface, with the direct oxidation process of oxidation operation, another kind is an indirect oxidation process of utilizing the indirect product of the hypochlorous acid that will produce after the chlorine electrolysis etc. to carry out oxidation.
Direct oxidation
The direct oxidation process is eliminated organism has following equation, the hydroxide radical OH that produces behind the brine electrolysis
-Anode attached to electrode surface (M[]).

The hydroxide radical OH of electrode surface merger

Here, the hydroxide radical OH by produce always
-Oxygenizement, can form the organic substance RO after oxidized, anode is discharge constantly in water.At oxidized anode (MO
X) adhered to the hydroxide radical that produces behind the brine electrolysis after, react with the oxygen that has produced, form further oxidized anode (MO
X+1).
In addition, organic substance (R) and the hydroxide radical reaction of adhering on the oxidisability anode resolve into carbonic acid gas, water, hydrogen ion, and reaction formula is as follows:

Indirect oxidation
By indirect oxidation, the electro-chemical reaction of eliminating organic substance be with electrolysis in the anodic oxidation of chlorine simultaneous, form hypochlorous acid at electrode surface.Utilize the hypochlorous acid that produces at anode like this, the reaction formula of oxidation of organic compounds matter is as follows:

Electrolytic process is as follows, is oxidized to continue oxidation behind the benzoquinones and form toxilic acid and carbonic acid gas, and reacting with oxygen forms competition, under hyperoxia and high pressure, prior to the oxygen generating process.

The chlorine that generates at first with reactivity preferably ammonia-state nitrogen combine, in water, decompose after generating combinative residual chlorine, form free residual chlorine.Therefore, combinative residual chlorine and chlorine/free residual chlorine reaction is carried out generating nitrogen after the oxidation again, realizes its elimination.
The same, according to electrolytic reaction, along with the electrolysis time of the regenerated sewage after handling in electrolysis treatment groove (11), i.e. the variation of time of in electrolysis treatment groove (11), stopping of mixing water, the water quality for the treatment of water also can change.
COD change in concentration in the treating water of table one ozonize and electrolysis treatment
Under the top condition of ozonize and electrolysis treatment, it is as shown in the table to the elimination degree of COD and T-N (total nitrogen).
Before flowing into the ozonize groove, COD concentration is 245.0mg/L, and the COD concentration in the treating water after the electrolysis is 40.8mg/L, has eliminated 83%.For T-N (total nitrogen), flowing into the preceding concentration of electrolysis treatment groove is 20.8mg/L, becomes 4.5mg/L after the electrolysis, has eliminated 78.4%.Therefore, under the top condition of this electrolytic processing apparatus, can effectively remove COD, BOD and T-N.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
