Sludge organism adhesion test structure

The utility model relates to a fouling organism adhesion test structure which comprises a frame body and at least one horizontally-arranged mounting frame, a mounting space used for containing the mounting frame is formed in the frame body, the mounting frame is used for mounting a test mesh, a sliding groove with at least one end of an open structure is formed in the mounting frame, and a guide part is arranged on the frame body; the guide part is detachably connected to the sliding groove, and the installation frame can slide relative to the frame body through cooperation of the sliding groove and the guide part so that the drawing-inserting installation frame can slide into or slide out of the installation space. The frame body is provided with a movable stop piece, and the movable stop piece can stop the installation frame. Wherein the movable stop piece is provided with a first position and a second position, the movable stop piece stops the mounting frame at the first position so as to limit the mountin
