Cultivating bed for granule sludge, cultivating system and cultivating method for granule sludge

The invention relates to a cultivating bed for granule sludge. The cultivating bed comprises a cultivating tank; a filling frame is arranged in the cultivating tank; a filler is arranged on the filling frame; the filling frame or filler is driven by a shock excitation device to mechanically vibrate in the cultivating tank; a water inlet, a water outlet and an emptying port on bottom are formed onthe cultivating tank; the cultivating bed is capable of cultivating aerobiotic or anaerobic granular sludge with high efficiency and low energy consumption and also can be used as a temporary or small-size sewage treatment device. According to the invention, microorganisms on filler are cultivated in the manner of vibration, are gradually covered on the filling frame under a vibrating state and are covered and overlapped; under different vibration intensities (such as increasing vibration amplitude or frequency), a special granular structure is formed on the filler surface; the grains fall offso as to form a granulate
