Study on Flocculation of Kaolin Beneficiation Wastewater by Chitosan
摘要
Abstract
[ Objective ] The research aimed to study the effect of chitosan on the floceulation performance of kaolin benefiriation wastewater. [ Method ] The floceulation experiment of kaolin beneficiation wastewater was carried out by using a lab-scale beaker. The effects of pH value and chitosan dose on removal rate of SS (suspended substance) were investigated. And the ζ potential values of particles were presented. [Result] The chitosan had excellent floceulation efficiency for SS. The removal rate of SS was 96% in the pH range of 4.0 - 7. 0 at the dosage of 8. 0 mg/L chitosan. It was presumed from ζpotential values of particles that the floceulation induced by chitosan was dominated by charge patch mechanism and bond bridging. [ Conclusion ] This research will provide scientific basis for the application of chitosan in the kaolin beneficiation wastewater treatment.关键词
