As shown in FIG. 1 and FIG. 2, the utility model provides a continuous flow CIAR sewage treatment system, which comprises:

the reaction tank is internally provided with a partition wall so as to divide the reaction tank into a pre-reaction zone 2 and a main reaction zone 3, the pre-reaction zone is communicated with a water inlet pipe 1, and the bottom of the partition wall is provided with a water flow hole 21 so that water in the pre-reaction zone flows into the main reaction zone; a sludge discharge pipe 83 is arranged at the bottom of the main reaction zone;

the aeration device comprises an aerator 7, and the aerator is arranged at the bottom of the pre-reaction zone and the main reaction zone;

a sedimentation separation tank 4, wherein the middle upper part of the sedimentation separation tank is provided with a water through hole 31 communicated with the main reaction zone, and the water through hole is also provided with a valve 32; the sedimentation and separation tank is further provided with a plurality of hollow fiber filter cloth discs 42 and a hollow water shaft 41, water permeable holes are formed in the hollow water shaft, the fiber filter cloth discs are fixed on the hollow water shaft, the interiors of the fiber filter cloth discs are communicated with the hollow water shaft through the water permeable holes, and a plurality of fiber filter cloth discs can be arranged on one hollow water shaft. Two ends of the hollow water shaft are arranged on the bracket, one end of the hollow water shaft is communicated with a water outlet area 5 outside the sedimentation separation tank, and the water outlet area is provided with a water outlet pipe 6 for discharging the treated sewage; the hollow water shaft is provided with a chain wheel 43 and further comprises a motor 44 for driving the chain wheel, and the chain wheel is connected with the motor through a chain. The support can be arranged in the sedimentation separation tank, and two opposite inner walls of the sedimentation separation tank can be used as the support to support the hollow water shaft. The fiber filter cloth disc is a hollow disc-shaped device with the surface provided with the fiber filter cloth, can bear larger sewage pressure, is communicated with an external water outlet area with smaller pressure, has large difference between the internal and external water pressure, allows cleaner water to enter the hollow water shaft through the fiber filter cloth, allows sediments to be blocked outside the fiber filter cloth, and has high filtering efficiency.
