AI Technical Summary

Technical Problem

Existing wastewater treatment devices suffer from clogged filters that are difficult to clean, low air ionization efficiency of disinfection gases, and significant loss of active purification components, resulting in poor impurity removal and inadequate disinfection.

Method used

The design incorporates a multi-stage interception and automatic impurity removal wastewater treatment device, employing a multi-stage filter screen self-cleaning mechanism and a high-efficiency air ionization disinfection system. By progressively reducing the filter pore size through multiple stages of filter screens, combined with a high-voltage power grid and a high-voltage discharge needle ionization chamber, the device enhances the filter screen cleaning capacity and air ionization efficiency, thereby improving the impurity removal and disinfection effects.

Benefits of technology

It achieves self-cleaning of the filter screen, improves the degree of automation and continuous operation capability, enhances the removal effect of solid impurities in sewage, and improves the disinfection effect and the concentration of active purification components through efficient ionization and uniform dispersion of disinfection gas, ensuring the full treatment of sewage.
