8. a kind of Hydrodynamic cavitation as described in any one of claim 1 to 7 claim subtracts the sewage water treatment method of mud machine, special
Sign is to include the following steps:
A. it is generated afterwards by the mud mixed liquid that no-blocking pollution discharging pump provides certain flow and pressure into the first cavitation device (103)
High-speed jet is impinged upon on the crushing baffle (102) of the first cavitation device (103) face, makes big in sewage mixed liquor
Grain sludge wadding body is broken, and the mixed liquor pressure in level-one cavitation chamber (101) is caused to further increase；
B. the sewage mixed liquor after level-one cavitation enters the second cavitation device (21), molten in second level cavitation apparatus (20)
Molten gas cavitation is generated under the collective effect of air cavity (23) and jet stream obligatory point (25)；
C. the sewage mixed liquor after second level cavitation is discharged after being handled by the cavitation apparatus that second level diffuser (26) enter downstream；
D. sewage mixed liquor will also fill after two-stage cavitation process by third level cavitation apparatus (30) and fourth stage cavitation
The cavitation step for setting (40) makes the fragmentation of sludge wadding body and hardly degraded organic substance therein is made directly to resolve into C02, H20, hardly possible drop
Solution organic matter macromolecular chain is fractured into small molecule chain, fatty acid is then oxidized to, to improve the biochemical of organic matter of sewage
Property.
