摘要
文章利用一株自筛的苏云金芽孢杆菌菌株ODPY对烟嘧磺隆废水及烟嘧磺隆生产中间体进行了降解研究。结果表明,菌株ODPY对烟嘧磺隆废水有一定的降解效果,其COD的去除率最大为23%,并且该菌株对烟嘧磺隆废水的降解中,对烟嘧磺隆中间体2-氯-N,N-二甲基烟酰胺、磺酰胺和磺酰胺甲酸酯的降解占据了重要地位,对这3种中间体的降解率分别为40.9%、71.5%和42.2%。
A Bacillus thuringiensis strain ODPY was related intermediates. The results indicate that used to degrade nicosulfuron wastewater and its the strain ODPY could degrade nicosulfuron wastewater with a maximal chemical oxygen demand（COD） removal rate up to 23%. Additionally, the COD removal rate of nicosulfuron wastewater by the strain ODPY is based on the degradation of three intermediates including 2-chloro-N, N-dimethyl-nicotinamide, sulfonamide and sulfonamide es- ter with the maximal degradation efficiency being 40. 9%, 71.5% and 42.2% respectively.
