30A。
Dissolved oxygen amount of the high pressure gas 30 to improve the waste water 90 as a result, so that the iron ion in the waste water 90
The flocculating result and bactericidal effect for accelerating the pollutant in the waste water 90 make pollutant coagulative precipitation, and are conducive to be collected and arrange
It puts.
In other embodiments, which includes a high pressure gas generation device 31 and multiple exhaust pipes
32, multiple exhaust pipes 32 are alongside one another, and be located at two neighboring pole plate (as shown in Fig. 2, for example the positive electrode plate 21 with should
Between electric induction pole plate 23, between the negative electrode plate 22 and the electric induction pole plate 23, the electric induction pole plate 23 and the electric induction pole
Between plate 23) between lower section.Each exhaust pipe 32 has multiple gas vent 32A, and high pressure gas 30A is through gas vent 32A
It is discharged into the waste water 90, and then generates multiple high pressure bubbles 321.The high pressure bubble 321 is moved up from 13 bottom of working space,
Moving process can take away the dirt (dirt generated including 90 sterilization process of waste water in the electrolytic sterilizing portion 20 on dependency structure
Reactant and adhesion on object, each pole plate).
Of the invention focuses on, and when being first passed through the waste water 90 to be processed to the closed container 10, is re-filled with the high pressure
Gas 30A just can improve the dissolved oxygen amount of the waste water 90 in the working space 13, can further pass through the electrode sterilizing portion 20
Iron ion improves the cohesion amount of the pollutant in the waste water 90.
Refering to Fig. 5, for the waste water of different initial soda acid (PH) values, cooperation is passed through the height of different air pressures to the closed container 10
Calm the anger body 30A, carries out the detection of the COD removal rate of waste water dyestuff, data as shown in Figure 5 can be obtained.Wherein, it closes
In COD removal rate, when the initial pH-value of waste water is between 3 to 9, COD removal rate, the first curve
L1 (2.0265bar, approximately equal to 2atm) and the second curve L2 (1.01325bar, approximately equal to 1atm) are significantly better than that third
Curve L3 (normal pressure).Thus the provable present invention is by the way of being passed through high pressure gas 30A, available preferable chemical oxygen demand
Measure removal rate, especially waste water pH-value be less than or equal to 7 in the range of when, effect is obvious.
Refering to Fig. 6, horizontal axis is different initial soda acid (PH) values, and the longitudinal axis is the remaining coloration (coloration of waste water dyestuff
Value).Wherein, after the high pressure gas 30A that the closed container 10 is passed through different air pressures is compared, the 4th curve L4 can be obtained
(2.0265bar, approximately equal to 2atm) and the 5th curve L5 (1.01325bar, approximately equal to 1atm), in the pH-value of waste water
In the range of 7, remaining coloration is superior to the 6th curve L6 (normal pressure).
Refering to Fig. 7, for the waste water of different initial soda acid (PH) values, cooperation is passed through the height of different air pressures to the closed container 10
Calm the anger body 30A, and the analysis for carrying out the ratio of the total iron of ferrous iron Zhan of waste water is compared, can be obtained the 7th curve L7 (2.0265bar,
Approximately equal to 2atm) and the 8th curve L8 (1.01325bar, approximately equal to 1atm), it is less than or equal to 7 in the pH-value of waste water
In range, the ratio of the total iron of ferrous iron Zhan is below zigzag line L9 (normal pressure).Wherein
The ratio of the total iron of ferrous iron Zhan is lower, and the ratio for representing the total iron of ferric iron Zhan is higher.
Further, Fig. 8 A, Fig. 8 B, Fig. 8 C, Fig. 8 D and Fig. 8 E are please referred to, is respectively (initial in the closed container 10
When pH value is 7) air pressure in normal pressure (not supplying), the practical photograph of 1bar, 2bar, 3bar, 4bar treated waste water, can
Clearly find out, air pressure is bigger, and treated in principle, and waste water is limpider.
For another example Fig. 9 A (waste water from dyestuff), Fig. 9 B (normal pressure), Fig. 9 C (1bar), Fig. 9 D (2bar), Fig. 9 E (3bar) and Fig. 9 F

It can be seen that, the air pressure being passed through is bigger, and upper clear liquid is limpider.
In more detail, since iron ion has ferrous ion and ferric ion etc., when dissolved oxygen rate improves, the present invention
Waste water in ferrous ion can be converted into ferric ion, more ferric ions helps to allow the pollutant in waste water
The efficiency for being condensed into jelly improves.Once pollutant coagulative precipitation, can (such as mud line belongs to by the spoil disposal mechanism of bottom
In the prior art, do not repeat here) exclude sludge.The positive electrode plate 21, the negative electrode plate 22 and any electric induction pole plate
If 23 when having consumption (consumptive material), can replace in due course.
Further, since the present invention is equipped with multiple electrodes plate, the reaction of electrolysis water is carried out after energization, not only give up water containing chlorine
Compound can also generate hypochloric acid water, and have the effect of sterilization.
In addition, the upward drift of the high pressure bubble 321 meeting that the exhaust pipe 32 being located at below each electrode plate is discharged, a side
The problem of face increases the flow disturbance in waste water, on the other hand can also take away the sundries for attaching to each electrode plate, and reduction is sticked.
Advantages of the present invention and effect are as described below:
[1] flocculating result of the pollutant in waste water is good.The present invention is passed through high pressure gas to the waste water in closed container, can
