| Cleaning and remediation of oil-contaminated areas are necessary and inevitable to protect environmental ecosystems and maintain human health. For this purpose, in this project, oil transfer centers of Isfahan (Maroon 7), Bandar Abbas (Qutb Abad), Lorestan (Asar and Pol Baba), Northeast (Shahroud, Imam Taghi and Torbat Heydariyeh), Noorabad (Fars), Southeast (Rafsanjan and Nain) and Kharg Island and Tehran Oil Facilities (Ray) constructed a land farm after obtaining the necessary permissions from the Environment Organization and the Waste Committee. Due to the climatic conditions, phytoremediation methods are also used to continue biological purification which in this process, priority is given to use with microflora and native plants. Landfarming bioremediation is considered the superior option in oil purification due to its ease of implementation, low energy consumption, and independence from complex equipment and machinery. The implementation stages of this project, first after site preparation including the evaluation and quantitative-qualitative analysis of pollution and physical and chemical properties of soil, design, and preparation of the necessary infrastructure to carry out the cleaning process and then contaminated soils are collected in a suitable area under Environmental organization approval. Then, after sieving (sifting the contaminated soils to separate the pieces of rock and sand) and transferring the sifted soils to the site, a biological cleaning operation is performed. This soil with a volume of 35,000 cubic meters was cleared. |
