A method for detecting biological fouling in the pipeline network of the old city

Abstract

The invention discloses a biological scale detection method for a pipe network in an old urban area. The method of ray detection detects and measures the thickness, step 4, classifying and marking according to the degree of adhesion and step 5, classifying and processing; the present invention uses the characteristics of biological fouling adhesion, and uses the pipe network in the old city to arrange lines, residential area distribution, and urban shopping malls. The distribution and traffic routes are analyzed to predict and segment the pipeline network lines that may have biological fouling in advance, and the detection efficiency is greatly improved. According to the classification and processing of the measured results, there is no need to separate and cut the detection processing, which saves time and effort and has high detection accuracy.

Description

technical field [0001] The invention relates to the technical field of biological scale detection, in particular to a biological scale detection method of a pipe network in an old city. Background technique [0002] Biofouling refers to the microbial deposits or biofilms that form on any surface that is actually immersed in an aqueous environment, which either affects the aesthetics of objects, or causes blockages in pipes, and is also known to accompany the growth of certain bacterial biofilms. Acids can also cause severe corrosion to occur. These bacterial biofilms are usually composed of sulfate-reducing bacteria that typically grow anaerobically in water in the presence of oil and natural gas; [0003] Most of the existing methods for the inspection and treatment of biological fouling in the pipeline network are to separate and cut off the pipelines, and then perform welding and connection reset after inspection and removal. This inspection and treatment method cannot pr...

Problems solved by technology

[0003] Most of the existing pipeline network biofouling inspection and treatment methods are to separate and cut off the pipeline, and then reset the welded connection after inspection and removal. This detection and treatment method cannot predict whether there is biofouling in the pipeline section in advance, and it is easy to ignore the slight adhesion of biofouling pipelines, while the pipelines with slight adhesion will evolve into high adhesion or heavy adhesion without treatment, which is more troublesome to deal with. At the same time, cutting and cutting will affect the overall compressive strength of the pipeline. Urban pipe network biofouling detection method to solve the problems in the prior art
