AI Technical Summary

Technical Problem

The existing activated carbon filtration process requires regular shutdown of the machine after adsorbing microplastics, resulting in a decrease in water treatment efficiency.

Method used

The method of combining semi-circular filter plate and stirring assembly is adopted to allow activated carbon particles to fully adsorb microplastics in the filter box, and some activated carbon particles are thrown to the discharge port through the anti-blocking component to discharge, avoid blockage and achieve continuous input and discharge.

Benefits of technology

There is no need to shut down regularly to replace activated carbon particles, ensure continuous adsorption operations, improve water treatment efficiency, and improve the purification effect of tap water through multiple separations.

Abstract

The invention relates to the technical field of tap water purification treatment, and discloses a tap water micro-plastic removal method which comprises the following steps: pretreating activated carbon, mixing activated carbon particles with tap water, adsorbing micro-plastic mixed in the tap water by utilizing the adsorbability of the activated carbon particles, and filtering out the activated carbon particles to obtain purified tap water. Tap water and activated carbon particles are stirred, part of the activated carbon particles are thrown to the discharge port to be discharged in the stirring process, regular shutdown for replacement of the activated carbon particles in the filter box is not needed, continuous feeding and discharging are achieved, continuous adsorption operation is guaranteed, and the working efficiency is improved; micro-plastics in tap water and crushed activated carbon residues are stably settled, clear water is independently discharged, and the purification effect is improved by separating the micro-plastics in the tap water for multiple times; activated carbon particles attached to the semi-arc filter plate can be stirred, and the activated carbon particles are effectively prevented from blocking the semi-arc filter plate.
