Abstract

The invention discloses an ultrasonic air-water backwash filter which comprises a tank body. A water inlet and outlet chamber is formed in the outer wall of the tank body and used for discharging sewage and feeding original water, an air-water backwash device is arranged at the bottom of the tank body and communicated with a clean water tank and an air supply device so that water and air used for backwash are provided, the air-water backwash device is connected with a clean water outlet pipe so that clean water is discharged, a supporting layer is arranged on the upper surface of the air-water backwash device, a filter material layer is arranged on the upper surface of the supporting layer, and an ultrasonic vibration device for washing surfaces of filter materials is arranged above the filter material layer. According to the ultrasonic air-water backwash filter, the filter materials are washed by the ultrasonic washing device before and in the backwash process, so that sewage on the surfaces of the filter materials falls off, surface particles are dissolved, subsequent backwash is easier, backwash water flow velocity is reduced, backwash water is saved, energy consumption is reduced, and time is shorted.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an ultrasonic air-water backwashing filter tank. Background technique [0002] Typical filter backwashing is to use vertical upward water flow to wash the filter layer. The principle of action is to use hydraulic shear and filter particle collision friction to make the dirt on the surface of the filter material fall off. The flushing effect depends on the flushing flow rate, and a certain water flow rate is required to give full play to the effects of hydraulic shearing and particle collision. To make the dirt adsorbed on the surface of the filter material fall off, the water flow rate required for backwashing is relatively large, so how to make the dirt adsorbed on the surface of the filter material fall off more easily is to reduce the flow rate required for backwashing, thereby reducing the energy. An important research direction of water consumption and back...
