Abstract
A particulate filtering device with a multi-layer water distribution and collection structure and a method for using the same are provided. The device includes a tank where a filtering space and a back flushing expansion space are formed. An upper water distribution pipe is arranged above the back flushing expansion space and is in communication with an ozone gas-water mixing pipe. Ozone enters the back flushing expansion space through the upper water distribution pipe and mix with water for reaction. Exhaust gas is discharged from the top of the tank. Powdered activated carbon may enter the tank through the upper water distribution pipe, and is intercepted at a space above the filtering space to form an activated carbon layer, to absorb organics dissolved in the water and catalytically decompose ozone. At least three water distribution and collection pipes are arranged on a layer basis in the filtering space.
