Abstract

The embodiment of the invention provides a pipeline flushing method and device, and relates to the field of environmental governance. The method comprises the steps that the thickness of a deposition layer in a pipeline is obtained, the flushing condition is obtained according to the corresponding relation between the thickness of the deposition layer and the flushing condition, the flushing condition corresponding to the thickness of the deposition layer is the condition that the thickness of a preset proportion of the corresponding deposition layer is damaged at minimum power consumption, and water flow is controlled to flush the deposition layer in the pipeline according to the flushing condition. The pipeline flushing method and device are used for solving the problems of complexity and high cost generated when harmful substances generated by microbial metabolism in the pipeline are treated through an existing treatment method.

Description

technical field [0001] The invention relates to the field of environmental governance, in particular to a pipeline flushing method and device. Background technique [0002] Sedimentation is common in urban sewage pipes. Sediments contain a large amount of organic substances. The space of sewage pipes is relatively closed and the air circulation is poor. An anaerobic environment is easy to form. Methanogenic bacteria and sulfate-reducing bacteria in sediments And other metabolic activities provide and provide the material basis and environmental basis. [0003] In an anaerobic environment, methanogenic bacteria will produce harmful gases such as methane through metabolic activities, and sulfate-reducing bacteria (SRB) will produce harmful gases such as hydrogen sulfide through metabolic activities. If these harmful gases are not handled properly, they will cause gas accumulation. Leakage will occur after reaching a certain concentration, which may cause personnel poisoning, ...
