At present, the dredging method of the urban drainage pipeline mainly adopts common methods such as hydraulic flushing and manual dredging, and the drainage pipeline is cleaned and dredged by a method of grabbing, flushing and sucking. However, the cleaning work is very difficult and the dredging frequency is not high due to the fact that the urban drainage pipeline is numerous and is in underground space narrow. Therefore, a new method is urgently needed to solve the problems of difficult dredging and easy blocking.

According to the scheme, through the combination of the inner filtering basket and the outer filtering basket, the inner filtering basket can be used for filtering larger substances such as leaves, plastic bags and stones, a layer of sponge is paved on the inner bottom surface of the outer filtering basket, water permeates the sponge to be discharged from the bottom surface filtering holes of the outer filtering basket, fine substances such as fine sand can be filtered out, but the filtering impurity removing capacity of the inner filtering basket is relatively weak, the filtering basket is easy to block, frequent dredging is needed, proper dredging time cannot be predicted, and the inner filtering basket is very troublesome for large-area urban use.
For another example, chinese patent application No.: 201621390344.9, publication date: patent literature of 2017, 6 and 27 discloses a sponge municipal sewage treatment system which comprises a sedimentation tank, an overflow tank, a grid tank, a water reservoir and a filtering and sterilizing device which are connected in sequence; the PP rainwater module is filled in the reservoir, the reservoir is provided with a sewage well, a backwash pipe and a lifting well, the bottom of the sewage well is provided with a sewage pump connected to the municipal sewage pipe, the bottom of the lifting well is provided with a lifting pump, the water outlet end of the lifting pump is connected to the backwash pipe through a backwash control valve, and the water outlet end of the lifting pump is also connected to the water inlet end of the filtering and sterilizing device through a reuse control valve; the water outlet end of the filtering and disinfecting device is connected with the recycling pipe, and the sewage draining end is connected with the municipal sewage draining pipe. The scheme adopts multistage precipitation and graded filtration to treat sewage before being discharged into municipal pipelines, and has the functions of sewage discharge and back flushing, but the scheme has the advantages of high construction cost and large use space, is not suitable for large-scale use of municipal drainage systems, is suitable for independent installation of a plurality of large pollution sources, and is discharged into the existing municipal drainage pipeline systems after sewage treatment.
