Abstract
The new biological flocculant Fe-CTS was prepared in order to enhance the solubility, stability and flocculation performance of chitosan flocculant. At the best CTS and Fe mass ratio of 2, the Fe-CTS structure had good flocculation effect and good enmeshment function on pollutants. With the dosage of 10 ppm, the sedimentation rate of simulated wastewater reached 95 %. The prepared flocculants were used for the ethanol wastewater treatment too and this new bio-flocculant Fe-CTS was shown to be an effective way to diminish the content of inhibitory compounds and could be used for the ethanol wastewater treatment. In order to expand the biological flocculation agent application scope, the new modified chitosan flocculant was used in the detoxification of the acid hydrolyzate of lignocelluloses materials for ethanol production. The new bio-flocculant was proved to have stronger adsorption effect on the acid-soluble lignin which had a serious impact on the subsequent fermentation process and difficult to remove.
