The invention relates to a high-densification slope filter which is developed by imitating the principle that a chub branchial filters hydroplankton. A group of (100 or more) unit hydra-screens with the thickness of 40mm are densely arranged on a support frame which can adjust inclination degree with a center distance of 100mm, the surface of each unit hydra-screen sprays a stock solution by a spraying pipe arranged on the top of each unit hydra-screen, and a small liquid collection groove arranged on the bottom of each unit hydra-screen collects concentrated solutions on the screen to form a branchial filtering unit; two branchial filtering units are placed in parallel, a liquid collection groove arranged on the lower middle part of a gap between the two branchial filtering units collects concentrated solution from both sides of the small liquid collection groove positioned below each unit hydra-screen, and a main liquid feeding pipe positioned on the upper part of the gap supplies original liquid to the spraying pipe on the top of each unit hydra-screen at the two sides through branched pipes so as to form a branchial filter. The branchial filter works depending on the pressure (about 20kpa), the concentrated solution on the screen is automatically collected through the small liquid collection groove and a total liquid collection groove, then filtered by the screen and finally discharged to the ground. The invention can be used for the primary concentration and filtering of suspending liquid and especially suitable for the primary filtering of a ship borne algae collecting system.
