摘要： PURPOSE:To rapidly control the proper injection amount of ozone even when the quality of a solution to be treated is changed by calculating the pseudo- primary reaction speed constant K1 of the solution to be treated and controlling the injection amount of ozone on the basis of the calibration curve formed at every constant K1. CONSTITUTION:In an ozone reaction tower 1 where ozone-containing gas is brought into contact with a solution to be treated, the solution to be treated is supplied to a liquid supply passage 2 and discharged from a drain passage 3. Ozone-containing gas is supplied to the reaction tower 1 from an ozone generator 4 by an ozone injection pipe 5 and exhaust gas is discharged from the reaction tower 1 from an exhaust passage 6. Further, the concn. of ozone dissolved in the treated solution or the concn. of ozone in the exhaust gas is measured by ozone densitometers 9, 10, 13. Furthermore, a pseudo-primary reaction speed constant K is operated from the measured value by an operation apparatus 14. A control apparatus 17 controls the injection amount of ozone on the basis of the calibration curve showing the relation between the injection amount of ozone and the concn. of dissolved ozone or the concn. of exhaust ozone prepared at every constant K1.

摘要： PURPOSE:To prevent the outflow of a filter material to a water collecting trough by providing an inclined perforated plate to the outside of the overflow wall of the water collecting trough along the overflow wall and providing a barrier plate whose inclination is reverse to that of the perforated plate from the part under the bottom of the water collecting trough to the part under the perforated plate. CONSTITUTION:A filter bed 2 packet with a filter material is provided in a filter tower 1 and bacteria are held to the filter bed 2 and raw water is passed through the filter bed 2, as an ascending current along with oxygen-containing gas, and filtered treated water is allowed to overflow to the water collecting trough 5 having an overflow wall 6 provided to the upper part in the tower 1. An inclined perforated plate 7, slopping down toward the overflow wall 6 and reaching the part under the bottom of the water collecting trough 5 at the lower end part thereof, is provided outside the overflow wall 6 of the water collecting trough 5 along the overflow wall 6. Further, a barrier plate 7 whose inclination is reverse to that of the perforated plate 7 is provided, from the part under the bottom of the water collecting trough 5 to the part under the perforated plate 7 so as to hold an interval from the lower end of the perforated plate 7. As a result, it can be effectively prevented that the filter material constituting the filter bed flows out to the water collecting trough during operation, and economical efficiency and workability are enhanced.

摘要： PURPOSE:To enhance the ozone absorbing efficiency of water to be treated by providing a packed bed under the water sprinkling device in a contact tank receiving ozone gas from the lower part thereof so as to position the same above the surface of the water. CONSTITUTION:A packed bed 11 is provided under a distributor 2 so as to be positioned above the surface of the water in a contact tank 1. The packed bed 11 is constituted of the packing material placed on a porous support plate 12. The water to be treated sprinkled from the distributor 2 flows down through the packed bed 11 to come into contact with the ozone gas rising through the packed bed 11 to absorb the ozone gas, and subsequently flows downward under the surface of the water to further come into contact with the ozone gas countercurrently to further absorb the ozone gas. The treated water having ozone absorbed therein enters a reaction tank 8 from a communication port 9 and flows upward to be discharged from an overflow port 10. Further, the water in the contact tank 1 is partitioned into many small sections by an accumulated body of grid bodies or honeycomb cylinders opened in up-and-down directions and, by arranging air diffusing spheres 3 to the lower parts of the centers of the respective small sections, water to be treated flowing downward is converted to plug streams and ozone absorbing efficiency can further be enhanced.

摘要： PURPOSE:To enhance the ozone absorbing efficiency of water to be treated by dividing the interior of a contact tank into a plurality of small sections opened up and down each having a specific size by partition walls and arranging air diffusing devices discharging ozone to the lower part in the tank directly under the centers of the respective small sections. CONSTITUTION:The interior of a contact tank 1 is divided into two or more small sections 4 opened up and down each having a cross-sectional area of 0.01-0.5m and a cross section aspect ratio of 1-2 by partition walls 3 and water to be treated is allowed to flow downwadly through the small sections 4 of the tank 1 as plug streams, Air diffusing spheres 5 are arranged directly under the centers of the respective small sections 4 to discharge ozone gas. Therefore, the ozone gas uniformly comes into contact with the water to be treated flowing down through the small sections as plug streams. By this method, the ozone absorbing efficiency of the water to be treated is enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for conditioning an ion exchange resin, in each of which the ion exchange resin can be cleaned or purified efficiently. SOLUTION: The bottom 1a of a column body 1 is formed into a panel-like shape expanded downward and the axial center of the column body 1 is a lowermost part. A hub part 2a of water collection/sprinkle pipes 2 is arranged just above the bottom 1a. A plurality of water collection/sprinkle pipes 2 are extended radially from the hub parts 2a. Each water collection/sprinkle pipe 2 has such an ascending gradient that the position thereof is made higher as it goes radially to the tip thereof from the hub part 2a so as to be not contacted with the bottom 1a of the column body. The ion exchange resin is introduced into the column body 1 from a tank 29, subjected to bubbling treatment with nitrogen gas from each water collection/sprinkle pipe 2, cleaned while being circulated through pipelines 11, 13, 15 and a return throw-in port 17 and then washed with ultrapure water. The cleaned ion exchange resin is transferred through pipelines 11, 13, 18. COPYRIGHT: (C)2011,JPO&INPIT
