Title:
OZONE TREATMENT DEVICE AND SLUDGE TREATMENT METHOD
Document Type and Number:
Japanese Patent JP2018008235
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ozone treatment device capable of separating sludge, a degraded article thereof and water at high accuracy while decreasing volume of the sludge by degrading the sludge sufficiently.SOLUTION: An ozone treatment device 100 has: a reaction tank 10 for treating ozone with a sludge-containing liquid and separating the same into a foam layer 20 containing a degraded article of the sludge and a liquid layer 40 containing water; a liquid supply part for supplying the sludge-containing liquid to inside of the foam layer 20; and a gas supply part 50 for supplying a gas containing ozone to inside of the liquid layer 40 at a lower side of the foam layer 20. The gas supply part supplies a gas so that a supply amount of ozone is 30 mg or more to 1 g of a floating matter contained in the sludge of the sludge-containing liquid and gas superficial velocity of the reaction tank is 0.0035 m/sec. or more.SELECTED DRAWING: Figure 1
