[0038] The water after sedimentation in the second sedimentation tank 19 is discharged into the disinfection assembly 20, first filtered out by the filter disc 2004 to remove the remaining floating objects, then dispersed by the orifice plate 2006, and evenly falls near the mounting frame 2002, and sterilized and disinfected under the action of the ultraviolet sterilization lamp 2007.
