AI Technical Summary

Technical Problem

In existing technologies, the dosage of flocculants relies on human experience and cannot be precisely controlled in real time according to changes in water quality, resulting in excessive or insufficient dosage, which affects the stability of wastewater treatment effect.

Method used

A control system based on flocculation sensors is adopted. Through flocculation sensors and control modules, including acquisition, judgment, processing and control modules, the number of suspended particles and flocculation images in the flocculation tank are monitored in real time. Machine learning models and historical control records are used to optimize the dosage of flocculant and the valve opening and closing angle to achieve precise control.

Benefits of technology

It improves the reliability and efficiency of wastewater treatment, reduces the waste of flocculants, ensures continuous optimization of flocculation effect, reduces the interference of human factors on treatment effect, and flexibly responds to different water quality changes.

Abstract

This invention relates to the field of wastewater treatment technology and discloses a control system based on a flocculation sensor, comprising: a control module for controlling the flocculation sensor; an acquisition module for obtaining flocculation images of the flocculation tank; a judgment module for comparing the number of suspended particles with the number of standard flocculation particles and determining whether to activate the dispensing mode based on the comparison result; a comparison of historical control records with the flocculation flow rate and determining whether to determine the valve opening angle based on the historical control records based on the comparison result; if it is determined that the valve opening angle is not determined based on the historical control records, the valve opening angle is determined based on a valve angle model; a processing module for determining whether to adjust the flocculation dosage based on the number of suspended particles, the number of suspended particles, and the number of standard flocculation particles; and a control module for setting a dispensing control factor for the flocculation dosage based on the flocculation temperature and adjusting the dispensing in the flocculation tank based on the optimization results. This invention improves the stability of wastewater treatment by controlling the dispensing dosage.
