研发以新型淀粉基改性絮凝剂为核心的强化絮凝技术是重金属废水高效处理的有效手段之一。项目基于安卓系统API接口设计理念与“乌贼”吸盘及触腕的功能结构特征，拟设计制备新型仿生（乌贼）絮凝剂。首先，在Fe3O4基础上构建富含乙烯基活性接口的Fe3O4@C=C接枝聚合公共平台。然后，选取–COO–、–NH–、–CS2、–SH等基团作为“乌贼”吸盘修饰淀粉制成链状柔性触腕，接枝聚合到Fe3O4@C=C上，获得仿生配位吸附结构的淀粉基重金属絮凝剂。研究该仿生絮凝剂对重金属离子的螯合絮凝性能与广谱作用。探究仿生配位吸附结构在重金属离子强化絮凝、协同/竞争吸附、吸附/解吸中的作用机制，建立仿生配位吸附结构与螯合絮凝性能之间的“构-效”关系，实现仿生絮凝剂对不同种类和形态的重金属离子广谱作用、强化絮凝、高效去除和解吸回收。该项目预期成果将为研发新型重金属絮凝剂和高效处理重金属废水提供理论依据和应用基础。

The enhanced flocculation technique that centers and focuses on the novel starch based modified flocculant is one of the effective ways to treat heavy metal wastewater efficiently. Based on the API interface design concept of Adroid system and the functional structure characteristics of "cuttlefish" sucker and contact wrist, a novel cuttlefish-like bionic flocculant is to be designed and prepared in this study. According to the Adroid API interface design concept, a public platform of Fe3O4@C=C rich in vinyl interface is built for graft and copolymerization. The groups such as –COO–，–NH–，–CS2， and –SH are selected as "cuttlefish" suction cups and modified on starch to synthesize flexible" cuttlefish" wrists. Those prepared "cuttlefish" wrists are grafted onto Fe3O4@C=C to prepare the cuttlefish-like starch based heavy metal flocculant with the bionic coordination-adsorption structure. The flocculation efficiency and the broad-spectrum effect of heavy metal ions by the bionic flocculant are investigated. The mechanism of the bionic coordination-adsorption structure on enhanced flocculation, cooperative/competitive adsorption and adsorption/desorption for heavy metal ions is elaborated and analyzed. And then, the "structure-effect" relationship between the bionic coordination-adsorption structure and the efficiency of heavy metal ions chelating and flocculation is established. It aims to realize the broad-spectrum effect, enhanced flocculation, efficient removal, desorption and recycling for different kinds and forms of heavy metal ions. The expected results of this project will provide theoretical and applied basis for the development of new heavy metal flocculant and the efficient treatment of heavy metal wastewater.
