Abstract
In order to explore the strengthening effect of the electric field on biodegradable oily soil, through designing 5 gradient electric fields of 0V / m, 50V / m, 100V / m, 200V / m, and 250V / m, the growth and reproduction changes and behavioural dynamics of the electric field on organisms were studied the impact of learning. On this basis, the effects of electric field on the oil-lowering ability of organisms, the accompanying migration characteristics of populations, in situ active replenishment, and the distribution characteristics of nitrate ions and sulphate ions in oily soils were analysed. The results show that when the electric field strength is 100V / m, the biological growth and reproduction rate is the highest, the number of bacteria is the largest, and the loss of nitrogen nutrients is the smallest; the effect on the oil-reducing ability of the oily soil is accordingly coupled effect> single bacteria effect> single electricity effect It shows that the effect of electric field coupling bioremediation technology on oily soil is remarkable.
