Analysis of Electrochemical Pretreatment Process of High-concentration Cyanide-containing Wastewater
In the pre-treatment engineering of high concentration cyanide containing wastewater,the most suitable reaction conditions for the electrochemical process are determined by analyzing different salt addition amounts,currents,and reaction times.Through actual operation data analysis,it is shown that under the condition of CN-concentration of 1 730 mg/L,electrochemical reaction zone volume of 500 L,reaction time of 3.0 h,electrode current of 1.0 A,and salt addition of 4 g,the cyanide content in the effluent of cyanide containing wastewater can be reduced to about 60 mg/L,with a removal rate of over 96%.
