This series of steps is added, increases the difficulty for the treatment of cost and operational administrative, simultaneously because taking longer efficient before adding
The quantity and activity of bacterium have declined.
（3）Environmental safety.Because microbial augmentation（Add strain or growth-promoting agent）Belong to invasive recovery technique, at present
The focus of dispute concentrates in open water body whether bring Environmental security sex chromosome mosaicism using biological reinforced bioremediation technology.It is multiple
Inoculating microbe certainly will be introduced by closing adding for microbial inoculum, and influence of these microorganisms to target water ecological setting is still unknown at present
Really.Microorganism activator is launched although there is no the problem of inoculating microbe, as a kind of adding for compound chemical reagent,
Its residual components（Such as organic matter or minor metallic element）Environmental risk caused by possible also should not be underestimated.Therefore, there is an urgent need to
A kind of microorganism enhanced technology that develop Noninvasive, that environment influence is small, effect is lasting.
