Activating agent for enhancing degradability of oil degrading bacteria as well as application and use method thereof

The invention discloses an activating agent for enhancing degradability of oil degrading bacteria as well as application and a use method thereof. The activating agent comprises a microorganism excitant, a vitamin solution and a trace element solution in the proportion of 1:1:1, wherein the three solutions are independently preserved before usage, the microorganism excitant contains 1.0-10.0mL/L of Tween80, 0.02-1.0g/L of KH2PO4, 0.01-0.5g/L of MgSO4.7H20, 0.15-4.5g/L of K2HPO4 and 0.5-20.0g/L of cane sugar, the vitamin solution contains 0.5-1.0g/L of vitamin A, 0.5-10.5g/L of vitamin B1, and0.5-10.0g/L of vitamin C, and the trace element solution contains 0.05-0.15g/L of zinc, 0.02-0.10g/L of cobalt,, 0.15-0.40g/L of manganese, 0.02-0.20g/L of copper, 0.04-0.35g/L of molybdenum, 0.02-0.15g/L of nickel, 0.04-0.30g/L of selenium, and 0.0007-0.003g/L of boron. When the activating agent is used, the microorganism activating agent accounting for 0.03% of the volume of oil sewage is respectively taken and directly added into a sewage treatment system once 7-14 days. The activating agent is used for oil sewage treatment and can enhance the degradability of oil degrading microorganisms.
