Abstract

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.

Description

technical field [0001] The invention relates to an activator for enhancing the degradation ability of oil-degrading bacteria and its application and application method. The activator is composed of biological stimulants, vitamins and trace elements, which can promote the growth of microorganisms, enhance metabolic activity, improve system stability and reduce processing costs. Background technique [0002] Sewage from slaughterhouses, dairy processing plants, restaurants, etc. contains a large amount of non-biodegradable oils and fats. If high-concentration oily sewage is discharged into the surrounding water without treatment, it will form an oil film on the water surface, hinder oxygen transmission, cause water hypoxia, and threaten the survival of aquatic animals and plants. In anaerobic biological treatment, grease will accumulate on the sludge surface, hinder the transmission of soluble pollutants, and reduce the degradation efficiency of microorganisms on pollutants; ...
