To solve the problem of difficult treatment oil-bearing dredging sediment, effects three methods microbial remediation, phytoremediation and combined bioremediation on oily river sediments were compared studied, influence factors remediation explored through static bacteria-fling tests. The results showed that method was better than single biological in treating bottom mud. oil content treated ...

In the process of steam injection development heavy oil, due to serious heterogeneity and interference channeling in high-permeability layer, there is a lot oily sludge produced liquid oil wells, which difficult deal with. According existing profile control technology related properties sludge, system was developed by using as main agent adding other additives. At same time, matching relationsh...

Most of our knowledge about pollutants and the way they are biodegraded in the environment has previously been shaped by laboratory studies using hydrocarbon-degrading bacterial strains isolated from polluted sites. In present study Gram-positive (Mycobacterium sp. IBBPo1, Oerskovia sp. IBBPo2, Corynebacterium sp. IBBPo3) and Gram-negative (Chryseomonas sp. IBBPo7, Pseudomonas sp. IBBPo10, Burk...

This study focused on the evaluation of the specific biological heat potential (hb) of a food-processing artificial wastewaterin the autothermal thermophilic aerobic treatment (ATAT) system. A novel experimental method was developed to evaluate the hb value by using the heat balance model under the steady state. This system was daily fed with oily and artificial wastewater at 21,460 mg l(-1) CO...

Large pilot scale bioremediation approaches were implemented for the treatments of oily sludge (OS) characterised by alkaline pH (pH > 9), high concentration metals (3% dry weight) and total petroleum hydrocarbons content (TPH) rangingbetween 22,000 67,300 mg kg ?1 from a Tunisian refinery. The included bioaugmentation biostimulation with autochthonous isolated bacterial strains consortia. Chem...
