| Abstract:In this work, the bacteria system for preparing bacterial cellulose (BC) was constructed by using acetobacter. The three-dimensional network BC was produced through optimizing its fermentation process. The BC green flocculant was prepared by further chemical modification on BC and its flocculation performance in papermaking wastewater was also evaluated. The positived results showed that the obtained BC held typical three-dimensional network structure. The carboxyl content of the BC green flocculant product increased significantly. It belonged to anionic flocculant based on Zeta potential test. The results of papermaking wastewater flocculation indicated that the BC flocculant had excellent flocculation ability and its turbidity removal rate reached 94.6%. |
