Ultrasound and biochemical synergistic intelligent control treatment system for laboratory wastewater
Addressing the issues of monotonous and fixed treatment processes,lengthy duration,and difficulties in treating macromolecules in laboratory wastewater treatment,a comprehensive system has been devised,integrating water storage,wastewater treatment,chemical dosing and adjustment,waste gas treatment,and intelligent control.This system categorizes the wastewater into four states based on chemical oxygen demand(COD)and p H levels,allowing for the selection of tailored combinations of treatment process modules,thereby enhancing treatment efficiency.Furthermore,the integration of ultrasonic and biochemical treatments is implemented to expedite the treatment process of laboratory wastewater.Experimental results from ultrasonic and biochemi-cal tests demonstrate an improvement of 18.84％in the removal rate of refractory organic com-pounds,alongside a COD removal rate of 87.67％,meeting the requirements of the urban sewage quality standard.The results preliminarily validates the effectiveness of this intelligent control treatment system,which provides a beneficial attempt towards achieving zero-waste discharge in la-boratory settings.
