The invention provides rotary disc type filtering equipment used for removing suspended matters in raw water. The rotary disc type filtering equipment can be used for occasions requiring the removal of suspended matters and impurities from the water, such as sewage filtering, process circulation water filtering or an MBR (membrane biological reactor). A driving device can drive a filtering disc to rotate only through a transmission shaft, a transmission chain and a transmission chain wheel, a water distribution device does not need to be driven to rotate by the driving device, and the driving energy consumption can be greatly reduced; through the oval filtering surface design, more filtering units can be soaked in water, the filtering area can be greatly increased, and the filtering efficiency is improved; through less instant reverse flushing area, the reverse flushing loss can be reduced; the filtering units do not need to be fixedly connected with the water distributing device, the operation stability of the equipment is improved; the manufacturing difficulty and the installation difficulty of the equipment are lowered. Compared with a turntable micropore filtering machine used in the prior art, the rotary disc type filtering equipment has the advantages that more energy is saved, the filtering area is larger, the reverse flushing loss is lower, and the processing and the installation are easier.
