S7: when the liquid capacity in static state deposition chamber gradually increases, positioned at the liquid height of filtering outer cylinder container bottom
Rise, and be gradually filled with to supernatant flowing lumen and filtrate flowing lumen, pass through the second filtrate flowing lumen in aqueous solution and passed through
When filtering ring, first passing through unhurried current channel reduces the flow velocity of aqueous solution, filters, is filtered again to aqueous solution using when filter ring
Flocculation object is fallen in down gradually downward on flocculation object diversion division, and eventually fall into it is intracavitary in static state deposition, while by vertically arranged
The second filtrate flowing lumen extend the total distance that flows up of aqueous solution, enable the flocculation object in aqueous solution in the effect of self weight
Lower sufficiently sedimentation downwards；
And the aqueous solution in the second filtrate flowing lumen, when being spilled over to the top of filtrate surge drum upwards, aqueous solution, which flows into, to exist
In rotating filter cartridge, under rotating filter cartridge high-speed rotation, aqueous solution is filtered again, falls in filtrate by the aqueous solution of rotating filter cartridge
In the inner cavity of surge drum, and the aqueous solution completed for final filtration.
