Abstract

An innovative approach to remediate oilfield produced water, a major environmental pollutant from the oil and gas industry has been demonstrated in this study. The technique combines: invasive wetland plant (Pistia stratiotes) used in absorbing and metabolizing hydrocarbons present in the oilfield formation water, biosurfactant from indigenous Bacteria making them more accessible for degradation and fertilizer NPK act as biostimulator. The main objectives of this technique are to remediate Total Petroleum Hydrocarbons (TPH) in an environmentally friendly manner to be a potential for the petroleum sector. The success of the technique is supported by the results of GC-MS analysis, which detected no hydrocarbon compounds in treated water. However, after treatment using the proposed combination 90.1% of the TPH was degraded, and the remaining 9.9% was adsorbed by the biomaterials. Thus, this study would present a potential breakthrough in the ongoing battle against pollution caused by the oil and gas industry.

石油烃污染地层水的环境友好处理:降解和吸附的机理和后果

该研究展示了一种创新的方法来修复油田采出水，采出水是石油和天然气工业的主要环境污染物。该技术结合了:入侵湿地植物(Pistia stratiotes)用于吸收和代谢油田地层水中存在的碳氢化合物，来自本地细菌的生物表面活性剂使其更容易降解，肥料NPK作为生物刺激剂。该技术的主要目标是以一种环境友好的方式修复总石油烃(TPH)，使其成为石油部门的潜力。气相色谱-质谱分析的结果支持了该技术的成功，处理后的水中没有检测到碳氢化合物。然而，在使用该组合处理后，90.1%的TPH被降解，其余9.9%被生物材料吸附。因此，这项研究将为对抗石油和天然气工业造成的污染提供一个潜在的突破。

期刊介绍： Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
