The utility model relates to a novel washing-free filtering system for aquaculture, which comprises a filtering tank which is internally divided into a plurality of functional areas by a plurality of vertical partition plates, and is characterized in that the functional areas comprise a physical filtering area, a plurality of biochemical filtering areas and a sterilization area, a bacteria room and a stirrer are arranged in the biochemical filtering areas, a hollow area is arranged at the lower part of the bacteria room, and the stirrer is arranged in the hollow area. A hollow-out area is arranged in the bacteria room, a conical dirt collecting part is arranged below the hollow-out area, a water inlet of the biochemical filtering area is located in the upper left side of the bacteria room, and a water outlet of the biochemical filtering area is located in the lower right side of the bacteria room, so that a multi-direction water flow mode that water flows from the bacteria room from high to low is formed; con
