Nankai students find flowers that can eat "dirty oil"

Purple jasmine, Impatiens, Petunia, these beautiful flowers can bloom in up to 1% oil polluted soil, and have good remediation effect on these oil polluted soil This is what Nankai University undergraduate students found after nearly two years of research At present, this achievement has applied for 3 patents and is expected to be applied to the remediation of polluted soil in Shengli Oilfield, Shandong Province This research was completed by the project team of "basic research on in situ phytoremediation of low and medium concentration oil contaminated soil" headed by Zhang Zhineng, an undergraduate of environmental science and Engineering College of Nankai University Zhang Zhineng said that at present, most of the petroleum contaminated soils in the world are treated and repaired by physical and chemical methods, chemical methods and high-efficiency degradation microbial methods The biggest disadvantage of these methods is that they have side effects and the cost is too high The phytoremediation method has the advantages of low cost, no secondary pollution, natural beauty and so on Therefore, under the guidance of Professor Zhou Qixing, Dean of the school of environmental science and engineering of Nankai University, their research team focused on plant restoration from the beginning In the research, they take Shengli oil field as the research base, and focus on the selection and research of native plants, flower plants and their related technological parameters suitable for in-situ restoration However, the three selected flowers made their research group "bright in the eyes", and their repair effect and tolerance were better It is understood that this achievement has been applied in a certain area in Shengli Oilfield and has achieved preliminary results According to reports, at present, in the field of research at home and abroad, there are few kinds of plants that can effectively degrade petroleum hydrocarbon pollutants However, the research on remediation plants for petroleum contaminated soil in China is still in its infancy, and there are few plants with independent intellectual property rights for remediation of petroleum hydrocarbon pollutants This study is the first in China to use green and original ecological methods, especially flowers and plants as remediation materials for oil contaminated soil remediation.
