摘要
研究了3种代表性阳离子絮凝剂:聚合氯化铝(PAC)、聚合硅酸硫酸铝(PASS)和聚二甲基二烯丙基氯化铵(PDADMA)对小球藻(Chlorella vulgaris)的浓缩效果,并对其实际应用的经济性进行了评价。结果表明,3种絮凝剂均能高效浓缩小球藻,但浓缩成本相对较高,因此,亟需开展优化絮凝工艺过程和开发高效低成本的絮凝剂研究,解决限制能源微藻产业快速发展的收集瓶颈问题。
Three kinds of typical cationic flocculants： aluminium polychloride（PAC）,polyalu-minium silicate sulfate（PASS） and poly（diallyldimethylammonium chloride）（PDADMA） have been studied for the recovery of Chlorella.vulgaris,and the economic evaluation for their utiliza-tion in microalgae biomass harvesting was conducted.The results showed that the three kinds of flocculants are able to recover C.vulgaris efficiently,but the cost is relatively high.Therefore,in order to reduce the cost of microalgae harvesting by flocculation technology,it is urgent to optimize the process of recovery and to develop cost-effective flocculants.
