An inorganic-biopolymers hybrid flocculant (PSAC-SA) was prepared by modifying sodium alginate onto polysilicate aluminum calcium (PSAC) through coordination between SA and Ca²⁺. The preparation conditions of PSAC-SA and the flocculation parameters that influence of the turbidity and color removal efficiency were investigated and optimized. The flocculation experiments results showed that the maximum turbidity and color removal could get 97.2% and 98.4% for kaolin-humic acid suspensions, respectively. The application of PSAC-SA for Songhua River treatment indicated that it had an excellent flocculation capacity in real water samples, and its flocculation efficiency was much better than that of individual flocculants (PSAC and SA). Moreover, the flocculation mechanisms were discussed in detailed, which indicated that the bridging effect and physical entrapment of solid particles played an important role in the flocculation process.

通过SA和Ca ²⁺之间的配位，将海藻酸钠改性到聚硅酸铝钙（PSAC）上，制备了一种无机-生物聚合物杂化絮凝剂（PSAC-SA）. 研究并优化了PSAC-SA的制备条件以及影响浊度和脱色效率的絮凝参数。絮凝实验结果表明，高岭土-腐植酸悬浮液的最大浊度和色度去除率分别为97.2%和98.4%。PSAC-SA在松花江处理中的应用表明，它在实际水样中具有优异的絮凝能力，其絮凝效率远优于单个絮凝剂（PSAC和SA）。此外，详细讨论了絮凝机制，表明固体颗粒的架桥效应和物理截留在絮凝过程中起着重要作用。
