According to my knowledge bio-char may be a good solution

I think it won't work in my case because of penetrating TBM in subsurface soil and bio-char can't reach to all polluted region

your idea is great but TBM is an odorant  that could be smelled even in very low concentration (0.2 ppb) so it's important to remove it from environment immediately ergo i I think bioremediation isn't such fast that I need

As you know, tert butyl mercaptan is volatile with relatively low Kow and aqueous solubility around 2000 mg/L. One would expect it to be susceptible to oxidation. You could determine the amount of oxidant needed by doing a total oxidant demand test of the soil as outlined in 2003 paper by Haselow et al. (Remediation,Autumn, 2003, pp 5-16).  

To remove it from soil, the most effective (and least costly method) would likely be air sparge and soil vapor extraction and I would start by doing that since it will reduce the oxidant demand of the soil (if you later wanted to amend with a chemical oxidant for example). Although the theoretical analysis of potential reactions is important, bench tests of soil samples from the site (using different oxidants) and a field pilot test will be the most effective way to solve your problem and will also provide insight into the theoretical reaction pathways.

To treat the off gas of an air sparge SVE you may want to consider a flame oxidation unit,  UV /ozone or other activated radical-based process. Researchers have also had success with sorption to activated carbon.

Joe Rossabi has given you the best advice.  If you want to be more aggressive you might use an ozoneator to add ozone to the air sparge.  Instead you could add hydrogen peroxide to the soil.  Overall a simple air sparge would probably be most cost effective.  To collect the soil offgas, cover the area with a plastic sheet and suck the air from under the sheet and send it to your offgas treatment system.

thanks for your advice but there is some issue about explosion due to TBM vapor

(it can explode even in low concentration about 1%) 

There is no way that you are going to get an explosion underground.  Associated with any explosive limit is a minimum dimension: that is why flame arrestors work.  If you are concerned with explosions in your offgas treatment system, either don't capture the gases or add air dilution before processing.
