The invention discloses a
bioremediation system for an organic contaminated site. The
system comprises a mixing and stirring module, an oil removal,
precipitation and water purification module, an enrichment and concentration module, a microbial inoculum /
nutrient solution /
mixed matrix injection module, a biological ventilation module, a
biological reactor module, a PLC
intelligent control module and a
bioremediation database module; a reuse water outlet of the biological
pile module is connected with the mixing and stirring module, the mixing and stirring module is provided with an available
water source and a contaminated soil inlet, and the enrichment and concentration module is provided with a
nutrient substance and dominant bacterium adding port. Two schemes of in-situ remediation (mainly adopting a biological ventilation technology) and ex-situ remediation (mainly adopting a
biological reactor technology) can be freely selected according to site requirements; the problems of intelligence, low equipment degree, high microbial inoculum cost and the like in the
bioremediation practice of the organic contaminated site are solved, and
intelligent decision suggestions in the designand implementation process can be provided for bioremediation
engineering in real time.
