Title:
SEWAGE SLUDGE FERMENTATION RAW MATERIAL AND SEWAGE SLUDGE TREATMENT METHOD
Document Type and Number:
Japanese Patent JP2023090456
Kind Code:
A
Abstract:
To provide a fermentation raw material that can stably progress aerobic fermentation and stably ferment sewage sludge without depending on the type of sewage sludge or the type of nutrient source material.SOLUTION: A sewage sludge fermentation raw material for aerobic fermentation includes sewage sludge and a nutrient source. The raw material contains 3.5 or more and 130 or less mass parts of crude fat and crude protein derived from the nutrient source per 100 mass parts of sewage sludge based on the total of the crude oil and the crude protein. It is preferable that the raw material contains 0.07 or more and 104 or less mass parts of the crude oil derived from the nutrient source per 100 mass parts of the sewage sludge. It is also preferable that the raw material contains 0.7 or more and 127 or less mass parts of the crude protein derived from the nutrient source per 100 mass parts of the sewage sludge.SELECTED DRAWING: Figure 1
