AI Technical Summary

Technical Problem

In existing wastewater treatment methods for recycled environmentally friendly corrugated cardboard production, filtration is prone to clogging, has low treatment efficiency, high labor costs, makes it difficult to achieve wastewater recycling, and results in serious water waste.

Method used

A graded filtration unit is used to separate impurities step by step. Combined with a dual-squeeze head dewatering and slag discharge structure and reverse air flotation centrifugal filtration, solid-liquid separation and removal of fine suspended impurities are achieved. The design incorporates an inverted quadrangular frustum coarse filter screen and a columnar filter screen, along with online extrusion dewatering, and reverse bubble and centrifugal force field treatment.

Benefits of technology

It achieves efficient filtration and purification of wastewater, solves the problem of filter clogging, improves operational stability, reduces labor costs, and realizes the recycling of water resources.
