| Abstract: | A combing process including flocculation-resin adsorption was applied to physico-chemical pretreatment of wastewater from cyclization section about metribuzin pesticide production.The optimum conditions were determined as flocculation 10% aluminum sulfate(W/W) as flocculants,dosing quantity 8%(V/V),by adjusting pH to 6~9,quickly stirring for 1min(150~180 r/min) and slowly stirring for 15 min(80~100 r/min).Resin adsorption was done under the conditions of effluent absorbed by double-column series at the flow... |
