| 摘 要： | 水处理混凝和絮凝过程中使用的药剂有凝聚剂、絮凝剂和助凝剂,其种类繁多,而新剂型的开发一直是絮凝工艺单元研究热点之一.分析了胶体颗粒脱稳凝聚过程中,凝聚剂、絮凝剂和助凝剂作用机理的差异,从化学组成、相对分子质量、生产来源和官能团的性质等角度,介绍了水处理工艺中常用混凝剂和絮凝剂的一般分类与典型代表物.明确指出絮凝剂的复配与"复合型"絮凝剂二者不同的技术特点,重点探讨了生物絮凝剂的复配使用与"复合型"生物絮凝剂的开发,并介绍了包括生物复合絮凝剂的研制和生物絮凝剂的复配.

| Abstract: | In the process of destabilization and aggregation of aquatic colloidal particles,different mechanisms of agglomerants,coagulants and flocculants were analyzed.Classification and representatives of coagulants and flocculants in water treatment were introduced from such aspects as chemical composition,molecular weight,production source and nature of functional groups.Different technical characteristics between combination effect of flocculants and compound flocculants were put forward.The properties and development of microbial compound flocculants and the combination effect between bioflocclant and other flocculants were investigated. |
