Since the aerobic tank 22 and the sludge tank 23 are interconnected, the sewage aerobically treated in the aerobic tank 22 enters the sludge tank 23 for sludge sedimentation treatment. Since the filter tank 24 and the sludge tank 23 are interconnected, the sewage in the sludge tank 23 can be partially returned to the filter tank 24.

The multiple sets of roller brushes 56 can intermittently wipe the elastic plate to remove sludge, and can simultaneously drive the arc gear 594 to rotate so that the vibration rod 59 reciprocates to vibrate the elastic plate in the filter tank 24 to vibrate the sludge on the elastic plate in the filter tank 24 to vibrate and fall off, so as to avoid large pieces of sludge staying on the elastic plate. The sludge that is vibrated and wiped can stay at the bottom of the filter tank 24 together for easy recovery;

[0122] S8, aeration operation is performed in the filter pool 24: the fan unit 81 is turned on so that the output end of the fan unit 81 outputs to perform aeration operation in the filter pool 24. By setting the aeration pipe 84 into an I-shape, aeration operation can be performed in a large area in the filter pool 24.

On the one hand, sufficient stirring and mixing effect can be generated to promote the circulation of water. On the other hand, a certain movement speed of the mixed liquid is maintained so that the remaining sludge is always kept in a suspended state in the mixed liquid, so as to further improve the disinfection efficiency of chlorine dioxide during the reaction;

[0123] S9, collecting the liquid in the filter pool 24: turning on the fifth suction pump 93 so that the output end of the fifth suction pump 93 outputs, so as to pump the liquid in the filter pool 24 into the collection barrel 91.

[0124] In summary, through the arranged sewage treatment component 2, after turning on the first suction pump 211, the liquid is sucked from the liquid inlet mixing component 3 and injected into the anaerobic tank 21 to perform anaerobically treatment on the sewage, and then the second suction pump 221 is turned on to suck the sewage anaerobically treated from the anaerobic tank 21 into the aerobic tank 22 for aerobic treatment of the sewage. Since the aerobic tank 22 and the sludge tank 23 are interconnected, the sewage aerobically treated in the aerobic tank 22 enters the sludge tank 23 for sludge sedimentation treatment. Since the filter tank 24 and the sludge tank 23 are interconnected, the sewage in the sludge tank 23 can be partially returned to the filter tank 24, and the third suction pump 241 is turned on. The third suction pump 241 can suck part of the aerobic treated sewage in the aerobic tank 22 into the filter tank 24 for reaction, and can perform multi-stage filtration on the sewage in the filter tank 24. Through the arranged sludge return component 4, the sludge can be further returned from the sludge tank 23 to the anaerobic tank 21 for reaction. Through the arranged sludge oscillation component 5, the second drive motor 53 is turned on, so that the output end of the second drive motor 53 outputs to drive the multiple sets of roller brushes 56 to rotate, so as to wipe the elastic plate located in the filter tank 24. The elastic plate can be intermittently wiped to remove the sludge through the multiple sets of roller brushes 56, and it can simultaneously The arc gear 594 is driven to rotate at the same time, so that the oscillation rod 59 reciprocates to perform a reciprocating vibration operation on the elastic plate in the filter tank 24, so that the sludge on the elastic plate in the filter tank 24 is vibrated and falls off, so as to avoid large pieces of sludge staying on the elastic plate. The sludge that is vibrated and wiped can stay at the bottom of the filter tank 24 together for easy recovery. The chlorine dioxide feeding component 6 is arranged to inject chlorine dioxide liquid into the filter tank 24 for disinfection. The chlorine dioxide concentration detection component 7 is arranged to detect the concentration of the chlorine dioxide liquid in the filter tank 24. When it is found that the concentration of the chlorine dioxide liquid is too low, the chlorine dioxide feeding component 7 is continued to be fed. The material component 6 injects chlorine dioxide liquid into the filter tank 24, and the fan unit 81 is turned on through the arranged aeration component 8, so that the output end of the fan unit 81 outputs, so as to aerate the filter tank 24. By setting the aeration pipe 84 into an I-shape, the filter tank 24 can be aerated over a large area. By setting the aeration head 85 to be narrow at the top and wide at the bottom, the gas outlet efficiency can be further increased. On the one hand, sufficient stirring and mixing effect can be generated to promote the circulation of water. On the other hand, a certain movement speed of the mixed liquid is maintained, so that the remaining sludge is always kept in a suspended state in the mixed liquid, so as to further improve the disinfection efficiency of chlorine dioxide during the reaction.

Performing sewage treatment on the liquid sucked into the liquid inlet mixing component (3): after starting the first suction pump (211), the liquid sucked from the liquid inlet mixing component (3) is injected into the anaerobic tank (21) to perform anaerobically treatment on the sewage. Subsequently, the second suction pump (221) is started to suck the sewage anaerobically treated from the anaerobic tank (21) into the aerobic tank (22) for aerobic treatment. Since the aerobic tank (22) and the sludge tank (23) are interconnected, the sewage aerobically treated in the aerobic tank (22) enters the sludge tank (23) for sludge sedimentation treatment. Since the filter tank (24) and the sludge tank (23) are interconnected, the sewage in the sludge tank (23) can be partially returned to the filter tank (24). The third suction pump (241) is started to suck part of the sewage aerobically treated in the aerobic tank (22) into the filter tank (24) for reaction. S3, performing a multi-stage filtering operation on the sewage in the filter pool (24): by deploying a filter screen set (242) and a plurality of filter screens (243), the sewage flowing through the filter pool (24) is subjected to a multi-stage filtering operation; S4, injecting chlorine dioxide liquid into the filter pool (24): turning on the switch of the metering pump (63) so that the output end of the metering pump (63) outputs, so as to absorb the chlorine dioxide solution in the dosing barrel (62) and inject it into the filter pool (24), so as to perform a disinfection operation in the filter pool (24); S5, performing a detection operation on the chlorine dioxide concentration in the filter pool (24): starting the third drive motor (72) so that the output end of the third drive motor (72) outputs, so as to drive the connection plate (76) to move in the left and right directions; at the same time, starting the push-down cylinder (77) so that the output end of the push-down cylinder (77) outputs, so as to drive the concentration detector (79) to move downward, so as to perform a chlorine dioxide concentration detection operation on the liquid in the filter pool (24); if the chlorine dioxide concentration in the filter pool (24) is detected to be low, the chlorine dioxide liquid is continuously injected into the filter pool (24) through the chlorine dioxide feeding component (6); S6. Continue the operation of returning the sludge: start the sludge return pump (42) so that the output end of the sludge return pump (42) outputs the sludge in the sludge tank (23) to return the sludge to the anaerobic tank (21), so that the sludge continues to undergo anaerobic reaction in the anaerobic tank (21); S7, performing an oscillating operation on the elastic plate in the filter tank (24) to remove sludge: starting the second drive motor (53) so that the output end of the second drive motor (53) generates an output to drive the plurality of roller brushes (56) to rotate so as to wipe the elastic plate in the filter tank (24). The plurality of roller brushes (56) can intermittently wipe the elastic plate to remove sludge, and can simultaneously drive the arc gear (594) to rotate so as to make the oscillation rod (59) reciprocate so as to perform a reciprocating oscillation operation on the elastic plate in the filter tank (24), so as to vibrate and remove sludge on the elastic plate in the filter tank (24), thereby preventing large pieces of sludge from remaining on the elastic plate. The sludge obtained through the oscillation and wiping can remain at the bottom of the filter tank (24) for easy recovery; S8, performing an aeration operation in the filter pool (24): turning on the fan unit (81) so that the output end of the fan unit (81) outputs gas for performing an aeration operation in the filter pool (24). By arranging the aeration pipe (84) into an I-shape, aeration operation can be performed in a large area in the filter pool (24). By arranging the aeration head (85) into a shape that is narrow at the top and wide at the bottom, the gas outlet efficiency can be further increased. On the one hand, sufficient stirring and mixing effect can be generated to promote the circulation of water. On the other hand, a certain movement speed of the mixed liquid can be maintained so that the remaining sludge is always kept in a suspended state in the mixed liquid, thereby further improving the disinfection efficiency of the chlorine dioxide during the reaction. S9, collecting the liquid in the filter pool (24): turning on the fifth suction pump (93) so that the output end of the fifth suction pump (93) outputs, so as to pump the liquid in the filter pool (24) into the collection bucket (91).
