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.

使用微生物联盟进行生物修复和根修复的去除石油-碳氢化合物污染物的现场试验。

石油废渣是有毒且危险的，这就是环境保护机构宣布将其处理列为首要任务的原因。物理化学疗法价格昂贵且对环境不友好，而替代性生物疗法成本较低，但总的来说其工作速度较慢。一种原位在半干旱气候下，在一个被炼油厂污泥污染的地区进行了生物修复和根治修复现场规模试验。生物修复和根际修复处理包括使用由促进植物生长的根瘤菌和降解多环芳烃的细菌组成的人工财团，以及将上述财团与牧场植物分别结合使用。根际调解表明，植被的发展有利于原生微生物群的发展，具有去除石油废物的潜力。推测这是由于生物处理7个月后总石油烃的减少。
