The objective of this research is to apply the microcosm technique to evaluate the capacity of residual sludge as bioremediators of soils contaminated with hydrocarbons. For this, an artificial contamination with Diesel was carried out in a sandy loam soil, in turn, the sanitization of the dehydrated residual sludge was carried out. Three microcosm units are established, each with 50 kg of contaminated soil with a concentration of 30,000 mg Diesel/kg of soil; the first microcosm is the control microcosm (100:000) made up of 100% contaminated soil, and no residual sludge aggregate, the M1 microcosm that presents the proportion of contaminated soil: residual sludge of 70:30, and the M2 microcosm with the proportion 50: 50. The 100 days of analysis to the microcosms show that the application of the residual sludge in the contaminated soils generated 95.01% of bioremediation in the microcosm M2, and 88.31% of bioremediation in the microcosm M1, in turn, the residual sludge application improved parameters such as hydrogen potential, electrical conductivity, C:N ratio, organic matter, and native soil microorganisms; on the other hand, the application of residual sludge will not increase the variation in heavy metals, and soil texture. Therefore, it is concluded that the application of residual sludge in contaminated soils generates a high percentage of hydrocarbon bioremediation, of which the microcosm technique can be identified for its control of parameters and general observation.
