摘 要:研究采用碱解法降解抗蚜威废水中的COD和抗蚜威。通过单因素试验考察了反应温度、初始反应pH值和保温反应时间等主要因素对废水中COD和抗蚜威去除率的影响。碱解法降解抗蚜威废水中COD和抗蚜威的优化条件:反应温度130℃,初始反应pH值为12、保温反应3 h,在此优化条件下,抗蚜威废水中COD的降解率为52.8%,抗蚜威的降解效果达到93.1%,BOD5/COD从0.03上升至0.42,废水可生化性得到大大提高。

Abstract:The degradation of COD and Pirimicarb in Pirimicarb wastewater by alkaline hydrolysis process was studied in this paper. The effects of reaction temperature, initial reaction pH and heat insulation time on the removal of COD and pirimicarb in wastewater were investigated by single factor tests. Results showed that the optimum reaction conditions were as followings: reaction temperature of 130℃, pH value of 2, and heat insulation for 3 h, and the regredation rate, reaction efficiency and cost were also considered. Under the optimized conditions, the COD and Pirimicarb degradation rate were obtained as 52.8% and 93.1%, respectively, and BOD5/COD increased from 0.03 to 0.42 indicating that the biodegradability of wastewater was greatly improved.
