BIOGAS PRODUCTION PROMOTER, AND BIOGAS PRODUCTION PROMOTING METHOD, ORGANIC WASTE TREATING METHOD, AND TREATING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a biogas production promotion agent whereby, in the anaerobic fermentation treatment of producing biogas from organic waste, it is possible to reduce the volume of organic waste and improve biogas production efficiency, and a biogas production promoting method, an organic waste treating method and treating device using the same.SOLUTION: A biogas production promotion agent is used in the anaerobic fermentation treatment of producing biogas from organic waste, and contains a nonionic surfactant composed of a compound represented by general formula (a): R-CO(OR)OR(where, Ris a C3 to 21 hydrocarbon group, Ris a C2 to 4 alkylene group, Ris a C1 to 3 alkyl group. m1 is an average repeating number of (ORto represent a number of 2-200).SELECTED DRAWING: Figure 1
