Executive Summary : | Water is paramount to the functioning of crude oil, tannery and textile effluent (CTT) contaminated soil, where it gets contaminated throughout the various processes and finally is released out as effluent laden with unwanted organic and inorganic pollutants including various classes of hydrocarbons, different heavy metals, and synthetic dyes. Large scale production of crude oil and its transportation leads to huge chances for oil spills into marine environments. The major parts of crude oil are hydrocarbon with low and high molecular weights and they are accessible by many microorganisms. The crude oil is an essential for petroleum, diesel production. Electrochemical oxidation (EO) methods have been widely used to treat electrokinetic electrolyte solution due to their ability to completely degrade all types of hydrocarbons, different heavy metals, dyes and due to the absence of harmful byproducts. Electrokinetic treatment with EO followed by electrolysis using an anode with high oxygen potential and corrosion stability, or by indirectly using appropriate anodically-formed oxidants such as chloride or hypochlorite, has been found to be more effective in degrading organic and inorganic pollutants.
Indirect EO process, relying on the oxidizing activity of intermediates (chlorine, hydroxyl) formed during the mineralization of organic compound or degradation of the hydrocarbons , heavy metals, and dye molecules, has been found to be efficient in the degradation of organic and inorganic compounds. The use of EO for the degradation of hydrocarbons, heavy metals, azo dyes, phthalates, phenols, and persistent organic pollutants. EO subsequent ultraviolet (UV) treatment has been found to increase the mineralization efficiency and reduce toxicity. The synergetic effect of ultraviolet light on the electrolyte solution can produce radicals which can help in the degradation of recalcitrant compounds into biodegradable compound. The aerobic biodegradation of electrolyte solution assessed after EO. The biodegradable efficiency of the mixed bacterial community can be explored by Metagenomic analysis. The bacterial communities were utilized for the degradation of organic content present in the electrolyte solution. Further chemical oxygen demand and total organic carbon levels will be monitored. Our objective is to develop an efficient and eco-friendly remediation technology for the remediation of crude oil, textile and tannery effluent contaminated soil. |
