The invention discloses an analysis and treatment method for a sewage pipe network system and a medium for storing the analysis and treatment method. A large amount of detailed information, such as the topological relation of the sewage pipe network and the detection data of the sewage pipe network, the water quality COD concentration, the water quality property, flow monitoring, the manually collected field data, etc., is utilized to judge whether a pipeline or a node has structural defects, the river surge water invasion point, the unsmooth circulation, the broken-end pipe section, the rainand sewage mixed connection node, and the direct discharge port nodes and the like, and the systematization, batch distribution, unified logic analysis processing is carried out, so that the timeliness and accuracy of data are guaranteed, the information support is provided for workers in time, the problems existing in the sewage system are further accurately and rapidly discriminated and classified, an effective scheme is provided accordingly, the quality and efficiency of the sewage system are improved, the effects after treatment are compared, and the implementation of subsequent strategiesis facilitated.
