Environment-friendly sewage discharge pipeline secondary recycling treatment process

Abstract

The invention relates to an environment-friendly sewage discharge pipeline secondary recycling treatment process. The process is mainly completed with the cooperation of an environment-friendly sewagedischarge pipeline secondary recycling treatment device. The environment-friendly sewage discharge pipeline secondary recycling treatment process specifically comprises the following steps of S1, preparing a pipeline; S2, placing the pipeline; S3, treating the pipeline; and S4, collecting the pipeline. The environment-friendly sewage discharge pipeline secondary recycling treatment process can solve the following problems, often generated when an existing sewage discharge pipeline is subjected to recycling treatment operation, that a, the existing sewage discharge pipeline is made of metal materials, and is often corroded and oxidized by sewage during sewage discharge operation, a large amount of rust is generated in the sewage discharge pipeline, then a user replaces the sewage dischargepipeline on which the rust is generated, and the replaced pipeline is discarded, so that the phenomenon of resource waste occurs greatly; and b, when the existing sewage discharge pipe is subjected to inner wall polishing, due to the fact that the pipeline is too long, the pipeline is polished often after sides of the pipeline are switched manually, so that the work intensity of workers is greatly increased.

Description

technical field [0001] The invention relates to the technical field of pipeline recovery, in particular to a secondary recovery and utilization treatment process for environmental protection sewage pipelines. Background technique [0002] Drainage pipes refer to the system composed of pipes and channels for collecting and discharging sewage, waste water and rainwater and their ancillary facilities, including main pipes, branch pipes and pipes leading to treatment plants. There are also more and more. In order to centralize the treatment of waste water, sewage pipes are often used to transport the waste water for unified treatment. Therefore, the use of sewage pipes is increasing. Therefore, in order to improve the utilization rate of metal materials and reduce unnecessary resources It is very necessary and urgent to recycle and reuse the sewage pipes. [0003] The existing sewage pipelines often have the following problems when performing recycling operations: a: The existi...

AI Technical Summary

Problems solved by technology

[0003] The existing sewage pipelines often have the following problems when performing recycling operations: a: The existing sewage pipelines are all made of metal materials, which are often corroded and oxidized by sewage during sewage discharge operations, resulting in a large amount of rust inside the sewage pipelines. The user replaces the rusted sewage pipes, and discards the pipes before the replacement, which causes a great waste of resources; b: when the inner wall of the existing sewage pipes is polished, the pipes are too long. Often the pipeline is polished manually after changing the side of the pipeline, which greatly increases the work intensity of the employees and poses a great safety hazard
