Title:
Ozone treatment equipment, sludge treatment equipment, ozone treatment method and sludge treatment method
Document Type and Number:
Japanese Patent JP6335750
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ozone treatment apparatus capable of increasing the reaction efficiency between a foamed sludge and ozone gas with an increased contact area between the foamed sludge and ozone gas.SOLUTION: An ozone treatment apparatus 1 includes an ozone reaction tank 2 and ozone treatment means 3. In the ozone reaction tank 2, ozone gas 9 is blown into a sludge-containing liquid 4 to cause foaming, so that a foamed sludge 6 is formed on the liquid level of the sludge-containing liquid 4. The ozone treatment means 3 takes the foamed sludge 6 out to be refined, so that a sludge 20 with refined foams is formed. The sludge 20 with refined foams is introduced into a region with the foamed sludge 6 in the ozone reaction tank 2.SELECTED DRAWING: Figure 1
