AI Technical Summary

Technical Problem

Existing industrial wastewater treatment devices cannot accurately identify complex pollutants such as heavy metals, oils, and microplastics, leading to the mixed treatment of wastewater with different levels of pollution, increasing treatment costs, and being easily clogged by suspended solids during electrodialysis desalination, affecting long-term operation.

Method used

Wastewater categories are determined by a testing agency, and multi-stage separation is achieved through a hydrocyclone separator and an electrodialysis membrane module. The controller adjusts the speed of the hydrocyclone separator and the voltage of the electrodialysis membrane module to achieve adaptive quality control, reduce energy loss, and prevent clogging.

Benefits of technology

It improves the accuracy of pollutant separation, reduces treatment costs, increases the reuse rate of industrial water, and reduces voltage requirements and maintenance costs.
