Effect of Silicone Oil on the Removal of o-Xylene from Waste Gases in Biotrickling Filters
摘要
Abstract
The strengthening effect of silicone oil in the biological treatment of o-xylene was studied in this paper. In shaker experiments, we investigated the solubilization effect of silicone oil on o-xylene and its influence on the activity of microbial degradation. Results showed that silicone oil has obvious solubilization effect on o-xylene, meanwhile, no influence on the activity of microorganisms. After biofilm was formed in the bio-tricking filter, the removal efficiency of o-xylene was investigated with 5%silicone oil (v/v) in the liquid phase. Under the same experimental conditions, the removal efficiency of o-xylene increased obviously when adding silicone oil with an inlet concentration of 600 mg⋅m-3. It was observed that, the biotrickling filter with silicone oil in the liquid phase exhibits enhanced efficiency in the removal of o-xylene, and the removal efficiency is about 10%higher than ordinary biotrickling filter. From the above results, it can be concluded that silicone oil can strengthen biological treatment of o-xylene.关键词
