Air aeration disk (11) provides sufficient oxygen for functional microorganism degradation of contaminant；
6) after aeration reaches the predetermined time, inspection by sampling soil and water pollutant concentration stop air exposure if up to standard
Enter, mud mixture is stood, and opens drainpipe (20), discharge after index to be determined is up to standard；If in mud mixture soil and
Water pollutant is below standard, then continues with, until pollutant processing up to standard.
10. a kind of method as claimed in claim 9, it is characterised in that：It is characterized in that, further include following operating procedure,
7) soil after being stood to processing up to standard in step 6) carries out outer row, first opens first motor (12), waits for electric gate valve
(13) after being raised above the height of cleaning shoe (16), first motor (12) is shut down, then mud scraper and sludge pipe (18) is respectively started
The sludge pump connected, under the drive of mud scraper, the soil of bottom sedimentation is discharged into soil collecting pit (17), and passes through spoil disposal
Pipe (18) is post-processed by outer row；
8) after the soil of the soil of first main reaction portion (1) bottom sedimentation and soil collecting pit (17) is all drained, the row of shutting down
The external sludge pump of mud pipe (18) starts first motor (12), electric gate valve (13) is made to drop to the bottom in the first main reaction portion (1)
Portion forms and is closed, then completes the ultrasonic cavitation, ozone oxidation and microbiological treatment of contaminated soil；
9) step 2) is repeated to 8), carries out the processing of subsequent batches contaminated soil.
