Abstract

Crude oil pollution in the environment poses grave ecological threat to the ecosystem and human health. In order to protect the ecosystem and public health, measures are required to remove pollutant from the environment. This study aims at investigating the crude oil polluted soil bioremediation enhancement efficiency of municipal drainage biosludge obtained from the Niger Delta region of Nigeria. Different quantities of dewatered biosludge collected from municipal drainage in the Niger Delta were used to treat microcosm of crude oil polluted soil in pilot scale bioreactors labeled A, B, C, D, E, F, G, H and I. Content of each set up was moisturized and mixed thoroughly at regular intervals. This was to ensure the provision of adequate water for microbes in the systems to thrive and to aerate the soil. The residual total petroleum Hydrocarbon (TPH) and other soil physicochemical properties of the soil were monitor for five months. At the end of the five months, TPH removal efficiency of 59.87%, 62.19%, 65.82%, 67.10%, 68.16%, 69.11%, 69.79% and 1% was recorded in set up A, B, C, D, E, F, G, H and I (control) respectively. Based on the results obtained in the study, it is concluded that municipal drainage biosludge obtained in the Niger Delta is potential supplement for the bioremediation of crude oil polluted soil.
