Separation and collection system and method for solid pollutants in solid-liquid mixed solution

Abstract

The invention discloses a separation and collection system and method for solid pollutants in a solid-liquid mixed solution. The system includes: a solid pollutant separation device, which mainly comprises a screen mesh; a screened garbage collection subsystem, which mainly comprises a solid pollutant flushing device for flushing solid pollutants separated by the solid pollutant separation device, a driving device of the solid pollutant flushing device, and a garbage storage device for storing the screened solid pollutants. The separation and collection system for solid pollutants in the solid-liquid mixed solution provided by the invention has the characteristics of simple structure and low cost, and the making cost is lowered by 50%-70% than ordinary vibrating screens. The screened garbage collection system adopted by the separation and collection system for solid pollutants in the solid-liquid mixed solution provided by the invention successfully solves the problems that planar screen garbage separation has large labor cost and the vibration screen cannot guarantee the screened garbage collection effect, and has excellent separation and collection effects in practical application.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation devices, and in particular relates to a system and method for separating and collecting solid pollutants in a solid-liquid mixed liquid. Background technique [0002] In sewage treatment and river dredging projects, the incoming sewage may contain plastic bags, waste fibers, stones and other garbage, which not only poses a threat to the normal operation of the disposal equipment, but also makes the treatment effect of the process unable to be guaranteed. Therefore, Must be removed prior to entering each disposal unit. [0003] At present, most of the related processes are equipped with screens, but there are problems that it is not suitable to remove the garbage and the meshes are easy to block. Moreover, the commonly used vibrating screens consume a lot of electric energy and cannot effectively separate the screens. out the trash. For example, the Chinese patent "A Self-cleani...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a system and method for separating and collecting solid pollutants in a solid-liquid mixture to solve the problem that the related screen technology in the prior art cannot be directly applied to sewage containing plastic bags, waste fibers, stones and other garbage Disposal and river dredging works, and the defects of high equipment cost
