Zusammenfassung:The invention discloses a double-compound magnetic modified flocculant for separating suspended particles in high-turbidity water as well as preparation and application of the double-compound magnetic modified flocculant. The magnetic modified flocculant is prepared by mixing and compounding two flocculant solutions of chitosan and cationic polyacrylamide in advance and then performing double-compound self-assembly double-compound with Fe3O4 magnetic particles. The preparation of the magnetic flocculant is further optimized, and the application range is not limited by pH. The optimized double-compound self-assembly magnetic modified flocculant not only overcomes the problems that chitosan is difficult to dissolve during use and is easily limited by operation conditions, but also can be recycled for multiple times and has a stable effect. Compared with general magnetic flocculation separation of suspended particles, the method further reduces the dosage of the flocculant, greatly improves the separation effici
