New treatment systems for soil contaminated by hydrocarbons

Abstract:

The present work analyzes several methods of soil treatment contaminated with hydrocarbons in order to reduce the concentration of total petroleum hydrocarbons (TPH), the methods evaluated yielded the following results: obtaining a 45.11% reduction in TPH for phytoremediation, 57.35-26.64% of TPH for vermirremediation, reduction in a range between 45-60% of TPH in a 5-week trial for fertilizers (N, K, P) and degrading heterophic bacteria, in chemical oxidation and compost polycyclic aromatic hydrocarbons (PAH) were reduced by decreasing by 70% in a 30-day trial, TPH was removed more effectively by bagasse by 60.01% versus 51.4% of the cachaza, in conclusion the treatments with The efficacy with respect to time and percentage of degradation were those of vermirremediation and the use of cachaza and bagasse.
