Method and system for analyzing pipe rainwater and sewage mixed collection distribution

Abstract

The invention relates to a method and system for analyzing pipe rainwater and sewage mixed collection distribution. The method comprises the steps of S1, grouping pipes and installing a liquid level meter; S2, screening inspection well water level data; S3, prejudging whether pipe sections are subjected to mixed collection of rainwater and sewage or not; S4, judging whether the pipe sections are subjected to mixed collection or not, and if yes, judging the mixed collection position. According to the method, by arranging the liquid level meter in an inspection well and acquiring liquid level data for a long term, through the combination of hydraulic calculation and analysis and big data analysis, the status quo of whether the sewage pipes are pipes subjected to mixed collection of the rainwater or not and area characteristic distribution are obtained; moreover, through liquid level data, the data is processed, through hydraulic power, flow is calculated to judge whether the phenomenon of mixed collection of the rainwater and the sewage exists among pipe sections in a sewage pipe network or not, the distribution of the pipe sections subjected to mixed collection is obtained, the specific positions of the pipe sections subjected to mixed collection of the rainwater and the sewage are judged in a more economic and safer mode, and data support is provided for later pipe updating andimproving.

Description

technical field [0001] The invention relates to the technology of checking the mixed connection of rain and sewage, in particular to a method and system for analyzing the distribution of mixed connection of rain and sewage in pipelines. Background technique [0002] With the development of the economy and the gradual deepening of urbanization, the urban population has risen sharply, and the amount of sewage discharged in the city is increasing day by day. Faced with the demand for urban infrastructure caused by economic development, water quality-type water shortage caused by water environmental pollution and the decline in the quality of life of urban residents Equal pressure, especially the mixed connection of rain and sewage, causes a large amount of rainwater to enter the sewage system during rainy periods, causing sewage pumping stations and sewage plants to discharge to rivers without receiving and treating them, resulting in poor water quality in rivers. For newly buil...
