Infiltration degree detection equipment of sewage drainage pipe network system

The invention relates to a sewage treatment system, in particular to infiltration degree detection equipment of a sewage drainage pipe network system, which comprises a main pipeline body, connecting flange plates are fixed at the edge of one side of the main pipeline body and the outer surface of a butt joint pipe, and a humidity detection device is arranged between the outer surfaces of the two connecting flange plates; the humidity detection device comprises a plurality of humidity detection sensors arranged in the humidity detection device, a clamping opening is formed in the humidity detection device, the humidity detection sensors are located in the clamping opening, an absorbent cotton pad is arranged in the clamping opening, and the absorbent cotton pad covers the outer surfaces of the humidity detection sensors. When the humidity detection device detects that water flow leaks out of the joint, blockage and accumulation are generated in the pipeline, meanwhile, along with the increase of the pressure
