Petroleum waste sludges are toxic and dangerous that is why environmental protection agencies have declared their treatment top priority. Physicochemical treatments are expensive and environmentally unfriendly, while alternative biological treatments are less costly but, in general, work at a slower pace. An in situ bioremediation and rhizoremediation field scale trial was performed in an area contaminated with oil refinery sludge under semiarid climate. The bioremediation and rhizoremediation treatments included the use of an artificial consortium made up of plant growth-promoting rhizobacteria and polycyclic aromatic hydrocarbon-degrading bacteria,and the combined use of the mentioned consortium along with pasture plants respectively. Rhizoremediation revealed that the development of vegetation favoured the evolution of indigenous microbiota with potential to remove petroleum wastes. This was inferred as the decline of total petroleum hydrocarbons 7 months after the biological treatment.
石油废渣具有毒性和危险性，这就是为什么环境保护机构将其处理列为首要任务。物理化学处理成本高昂且对环境不友好，而替代性的生物处理成本较低，但总体而言，处理速度较慢。在半干旱气候下，对一个被炼油厂污泥污染的地区进行了原位生物修复和根际修复的田间规模试验。生物修复和根际修复处理分别包括使用由促进植物生长的根际细菌和多环芳烃降解细菌组成的人工菌群，以及将上述菌群与牧草植物联合使用。根际修复表明，植被的生长有利于具有去除石油废物潜力的本地微生物群的进化。这是通过生物处理7个月后总石油烃的减少推断出来的。
