摘  要:
以聚合氯化铝(Poly aluminium chloride,PAC)为絮凝剂,利用响应面法对普通小球藻Chlorella vulgaris的絮凝工艺进行优化。研究结果表明:影响C.vulgaris絮凝效率的主次因素顺序为絮凝时间>C.vulgaris初始OD值>PAC浓度;C.vulgaris的最佳絮凝工艺为:PAC浓度为57mg·L~(-1),C.vulgaris初始OD值为2.06,絮凝时间为18min。在此絮凝条件下,C.vulgaris的絮凝效率为95.82%。研究结果将为进一步研究C.vulgaris的絮凝采收工艺提供数据参考和技术支持。

摘  要:
Flocculation of Chlorella vulgaris using Poly aluminum chloride(PAC)was optimized by theresponse surface methodology.The factors that affected the flocculation efficiency were in the order flocculation duration>initial OD value of C.vulgaris> PAC concentration.The optimized flocculation conditions included a PAC concentration of 57mg·L~(-1),an initial OD value of C.vulgaris of 2.06,and flocculation for 18 min to achieve a maximized efficiency of 95.82%.
