Bioremediation is a process used to treat contaminated media, including water, soil and subsurface material, by altering environmental conditions to stimulate growth of microorganisms and degrade the target pollutants. In many cases, bioremediation is less expensive and more sustainable than other remediation alternatives. Biological treatment is a similar approach used to treat wastes including wastewater, industrial waste and solid waste.

An on site bioremediation system that delivers logarithmically growing, active microorganisms from the culture vessel directly to the biodegradable waste to be metabolized is disclosed. The system includes a controller, culture vessel and separate containers of stock microorganisms and nutrient medium. The periodic or continuous addition of stock microorganisms and fresh nutrient media is controlled by a computer. After a particular cell density is reached, the active, logarithmically growing microorganisms flow out of the system to the waste site on a periodic or continuous basis.

The invention discloses a solid microbial agent used for remedying the soil contaminated by petroleum, belonging to the technical field of bioremediation of soil contaminants. First-class seed liquid of acinetobacter radioresistens and rhodococcus erythropolis are mixed in equal parts after two steps of fermentation in liquid and solid states and cultivation to obtain the solid microbial agent, wherein, the number of effective viable bacteria of acinetobacter radioresistens and rhodococcus erythropolis is 10 to 10 CFU/g. The solid microbial agent in the invention has the advantages of low cost, high number of viable bacteria; the invention further has the advantages that micro-ecological environment improvement of the soil can be improved and secondary contamination cannot be caused to the environment, thus applicable to the bioremediation of the soil which is contaminated by petroleum and petroleum products.
