| Abstract: | In order to eliminate the influence of waste alkali liquor from dichloroethane production by oxy-chlorination process on the water treatment efficiency,it was separately treated by distillation.The dichloroethane concentration was decreased below 1 μg/g,which met the specification of wastewater treatment.Profit from the reconstruction project,stable production and synthetic utilization of waste alkali liquor were realized,meanwhile,good economical and environmental benefits were also obtained. |
