METHANE FERMENTATION TREATMENT SYSTEM OF GARBAGE - MITSUI E&S ENV ENGINEERING CO LTD

Title:

METHANE FERMENTATION TREATMENT SYSTEM OF GARBAGE

Document Type and Number:

Japanese Patent JP2018176005

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a methane fermentation treatment system of garbage which can increase a generation amount of methane gas even when a VS capacity load increases in methane fermentation treatment of garbage slurry with a high TS concentration.SOLUTION: A methane fermentation treatment system includes a slurry preparation device 1 for obtaining slurry by treating garbage, a slurry tank 2 for storing the slurry obtained by the slurry preparation device 1, and a methane fermentation tank 3 which introduces the slurry in the slurry tank 2, contacts the slurry with methanogen in a fluid state, and generates methane by methane fermentation treatment. A total solid content concentration (TS) of the slurry is 10-30 wt.%. The slurry preparation device 1 or the methane fermentation tank 3 has adding equipment which can add Fe, Ni, and Co to the slurry.SELECTED DRAWING: Figure 1
