Background

In conventional water treatment, filtration generally refers to a process flow of retaining suspended impurities in water by using a granular filter material layer such as quartz sand, anthracite and the like, passing the water through a filter medium, and retaining particles on the surface of the medium or in the medium layer so as to clarify the water. The filtering function is not only to further reduce the turbidity of the water, but also to remove the organic matters, bacteria and viruses in the water along with the reduction of the turbidity of the water. When the bacteria, germs and the like remained in the filtered water lose the protection or attachment of the turbid matters, the bacteria, germs and the like can be easily killed in the disinfection process after filtering, so that good conditions are created for the disinfection after filtering.

In the process of carrying out precipitation filtration treatment on sewage by using the conventional water treatment equipment, the upper clear water in the precipitated sewage is generally pumped out to the filtration equipment for filtration, and then the filtered water is discharged for disinfection treatment; the existing filtering equipment generally adopts a filter element filled with a filtering medium to filter water, and because the gap between the filtering media filled in the filter element is difficult to accurately control, the gap between a part of filtering media can be larger than the diameter of impurities needing to be filtered, so that suspended impurities in water can not be completely treated by single filtration; simultaneously in the sedimentation process, after adding the flocculating agent, need stir sewage to the impurity of sewage and the bonding speed of flocculating agent are accelerated, and current stirring operation mostly uses electric drive's agitating unit to stir, need consume a lot of electric energy.
