Microbial flora activator, anti-filamentous fungus agent containing the microbiota activator as an active ingredient, and method for treating wastewater containing fats and oils using the microbiota activator

摘要

Disclosed is a microflora activator that prevents recombination of dispersed fats and oils and activates microorganisms in an activated sludge treatment system, and a method for treating wastewater containing fats and oils using the microbe flora activator. For the purpose. Provided is a microflora activator comprising 0.0005 to 8% by weight of a polyoxyalkylene alkyl ether having 13 to 22 carbon atoms and 0.0005 to 2% by weight of a fatty acid dialkanolamide as a main component, and water as the balance. In addition, the microflora activator is introduced into the raw water, the fats and oils in the raw water dispersed by the microbiota activator are removed together with other organic pollutants, and the settleability of the activated sludge itself in the aeration tank is reduced. Provided is a method for treating wastewater containing fats and oils and the like, each of which is capable of stably separating specific gravity without adding a coagulating precipitant by promoting endogenous respiration by microorganisms in activated sludge.
