Colored Concrete Sewer Pipes Manufactured by manufacturing process and colored concrete sewer

摘要

The present invention relates to a process for producing a colored sewage pipe having a colored sewage pipe formed of concrete, and more particularly, it relates to a process for manufacturing a colored sewage pipe which can effectively prevent color change even if a colored sewage pipe is buried underground for a long time, The invention being thus described.;Conventionally, when sewage having different components are introduced into a sewage end treatment plant, it is difficult to precisely grasp the components thereof, and it is difficult to inject appropriate treatment chemicals, which causes considerable difficulty in processing sewage.;The present invention is characterized in that the sewage pipe manufacturing process is carried out in the order of the first mixing step, the second mixing step, the third mixing step, the kneading step, the molding step and the drying step to form a colored concrete sewer pipe It is possible to obtain a concrete sewer pipe having an even color of powder color in the entire concrete sewer pipe. Even if such sewer pipe is buried in the ground for a long time, the color can be accurately discriminated and separated according to the type of sewage, The thus sorted and discharged sewage is introduced into a sewage end treatment plant and it is possible to effectively treat the wastewater by appropriately adding medicines according to the type of sewage.
