中文摘要 | [目的]研究一株海水藻类培养液的絮凝活性及机理。[方法]由实验室分离保存,一株海水来源的石莼(编号S307)培养液,分析不同因素下该培养液对高岭土悬液的絮凝效果,并探讨絮凝成分及机理。[结果]海藻S307的培养液具有良好的絮凝活性,并且具有较好的热稳定性。在实验室条件下,S307培养液投加量为8%(v/v)时,对高岭土悬液的絮凝活性可达72%;絮凝体系为碱性时,絮凝效果最好;其作用的最佳Ca2+浓度为3.6 mmol/L;结合紫外扫描和絮凝机制的研究结果,初步推测培养液中主要的絮凝物质应该为S307在生长过程中产生的核酸类物质,其中可能含有少量的胞外多糖,主要以离子键结合絮凝高岭土颗粒。[结论... |
英文摘要 | The study aimed to analyze flocculating activity and mechanism of a novel marine algae culture medium.Method]The flocculating activity of culture medium of S307,a type of marine algae Ulva lactuca L.,isolated from Beihai Guantouling intertidal of Guangxi Province,was tested in this study,and the effects of medium concentration,pH,cationic salt concentration and temperature on the flocculating activity were analyzed. Finally,the flocculating ingredient and mechanism were discussed.[Result]S307 culture medium had good flocculating activity and thermal stability. The flocculating rate against kaolin suspension could reach 72% when the concentration of S307 culture medium was 8% ( v /v) ; optimum pH for the flocculating activity of the system was 12; the optimum efficiency would occur as Ca2+ concentration was 3.6 mmol /L. The results of UV spectrum scanning and flocculating mechanism research indicated that the main flocculating ingredient in the medium was nucleic acid substance,and the medium might contain some extracellular polysaccharide. Moreover,the flocculating ingredient bonded with kaolin particles through ionic bonds rather than hydrogen bonds. [Conclusion]The research provides a novel flocculant for wastewater treatment |
