A secondary recycling treatment process for environmental protection sewage pipelines

Abstract

The present invention relates to a secondary recycling and utilization process for environmental protection sewage pipelines, which is mainly completed by a secondary recycling and utilization processing device for environmental protection sewage pipelines. ; S2, pipeline placement; S3, pipeline treatment; S4, pipeline collection; the present invention can solve the following problems that existing sewage pipelines often have during recycling and processing operations: a: the existing sewage pipelines are all made of metal materials. Sewage discharge operations are often corroded and oxidized by sewage, resulting in a large amount of rust inside the sewage pipeline. Afterwards, the users will replace the sewage pipeline with rust and discard the pipeline before the replacement, which is a huge waste of resources. Occurs; b: When the inner wall of the existing sewage pipeline is polished, because the pipeline is too long, the pipeline is often changed manually and then the pipeline is polished, which greatly increases the work intensity of the employees.

Description

technical field [0001] The invention relates to the technical field of pipeline recycling, in particular to a secondary recycling and utilization processing process for environmental protection sewage pipelines. Background technique [0002] Drainage pipeline refers to the system composed of pipes and their ancillary facilities that collect and discharge sewage, waste water and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. There are also more and more. In order to centrally treat wastewater, sewage pipes are often used to transport wastewater 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 sewage pipes. [0003] Existing sewage pipelines often have the following problems when performing recycling operations: a: The existing sewage pipelines are all made of ...

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
