Bioremediation of oily sludge-contaminated soil by stimulating indigenous microbes.
In situ bioremediation of oily sludge-contaminated soil by biostimulation of indigenous microbes through adding manure was conducted at the Shengli oilfield in northern China. After bioremediation for 360 days, total petroleum hydrocarbon (TPH) content was reduced by 58.2% in the treated plots compared with only 15.6% in the control plot. Moreover, bioremediation significantly improved the phys...

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Evaluation of bioaugmentation and biostimulation effects on the treatment of refinery oily sludge using 2(n) full factorial design.
Bioremediation approaches for the treatment of oily sludge from a refinery were evaluated using a 2(3) factorial design. The three strategies tested were bioaugmentation with indigenous microbial consortia (MO) isolated from oily sludge, biostimulation with nutrients (NP) and biostimulation with the surfactant Triton X-100 (TX). Eight experimental runs were conducted in triplicate with factor s...
متن کاملPrepared bed bioremediation of oily sludge in an oilfield in northern China.
Field-scale bioremediation of oily sludge in prepared beds was studied at Shengli oilfield in northern China. The influence of manure, coarse sand, sawdust, a specialized microbial preparation and greenhouse conditions on the efficiency of removal of oil and grease was evaluated. After bioremediation for 230d, oil and grease content fell by 32-42gkg(-1)dry sludge in treated plots, indicating re...
متن کاملMicrobial Bioremediation of Polycyclic Aromatic Hydrocarbons (PAHs) in Oily Sludge Wastes
Polycyclic Aromatic Hydrocarbons (PAHs) are fused-ring hydrocarbon compounds that are highly recalcitrant under normal conditions due to their structural complexity and strong molecular bonds. These groups of petrochemicals are mainly found in petroleum-refining plants, accidental oil spills and pipe leakages, and rainwater run-off from roadway. Improperly managed and disposed PAHs can cause en...
