Description

technical field

[0001] The invention relates to the technical field of filtration equipment, in particular to a microfiltration machine with a backwashing device and a microfiltration and sedimentation integrated machine. Background technique

[0002] The microfilter is a screen filter that traps fine suspended matter. Usually, a microporous screen of 80-200 mesh / square inch is fixed on the drum type filter equipment, and the solid particles in the water are intercepted through the screen to achieve solidification. liquid separation. The working principle of the horizontal drum microfiltration machine is: the treated water enters the drum of the horizontal drum microfiltration machine along the axial direction, and flows out through the screen in a radial radial shape, and the fine suspended matter in the water is trapped in the horizontal drum microfiltration machine. The inner surface of the filter screen on the drum of the rotary drum microfiltration machine. When the i...
