甲苯对生物滴滤塔微生物EPS的影响
Effect of toluene on the EPS in the microorganisms of biotrickling filter
摘要
Abstract
Volatile organic compounds(VOCs)have the characteristics of wide sources,numerous varieties,and tremendous hazardous. To improve the removal efficiency of VOCs,an extensive toluene treatment experiment was continuously conducted using biotrickling filter. The effect of toluene inlet concentration on the removal efficiency and extra-cellular polymeric substance(EPS)of biofilm in the biotrickling filter were investigated. The results showed that the removal efficiency of toluene was higher than 95%,and the EPS was 339mg/L when the inlet concentration of toluene and the spray volume were 284mg/m3 and 3.7—6.3L/h,respectively. With the increase of inlet concentration,the protein concentrations and polysaccharide in the loosely bond extra-cellular polymeric substances (EPS-LB)increased to a peak values of 108.93mg/L and 103.95 mg/L,respectively before they dropped. The change of protein and polysaccharide concentration in the tightly bond extra-cellular polymeric substances(EPS-TB)was similar to that of EPS-LB. It was not conducive to remove toluene in the biotrickling filter when the spray water volume was less than 3L/h or more than 7L/h. Pressure drops increased with the increase of inlet flow and EPS,and they were significantly higher at the end of experiment than those at the beginning of the experiment. However,the pressure drops of the biotrickling filter were remaining at low value.关键词
