| 摘 要： | 以杀菌剂百菌清为研究对象,向供试土壤中通入臭氧,通过改变臭氧通入量和臭氧通入的频次,进行百菌清降解试验.结果表明,臭氧通入量达到400 mg时百菌清降解效果最好,对百菌清初始质量分数分别为10、20、50 mg/kg的土壤总降解率分别为67.3％、67.7％和68.8％；在臭氧通入的初期,通入频次由1次/d增加到4次/...

| Abstract: | An experiment was conducted to study the effects of mass and frequency of ozone pumped into the soil samples on the degradation of chlorothalonil.Results showed that the best degradation efficiency was obtained when 400mg ozone was pumped into the soil.The degradation rates for the soil samples with initial chlorothalonil contents of 10,20,50mg/kg were 67.3%,67.7% and 68.8% respectively.At the early stage,as the frequency of ozone pumped into the soil samples increased from 1 to 4 times per day,the degradation rate of chlorothalonil in the soil samples with initial chlorothalonil content of 10mg/kg increased from 25.0% to 41.6% on the 5th day.It was found that the degradation rate of chlorothalonil could be effectively improved by increasing the mass of ozone or frequency of ozone under the same mass. |
