| Abstract: | The research in degradation mechanism of biofilm for removal of H2S gas treatment plant was investigated.Using the ultrasonic method could peel off the biofilm on packing,and the experimental results indicate that the rate of the extraction is better in 25 min.Phenol-sulfuric acid method could analysis extracellular polymeric polysaccharides,which is convenience,high recovery rate and good stability. |
