摘　　要：研究表明,将纳米级二氧化硅与聚合硫酸铁复配后用于絮凝实验,较单一的聚合硫酸铁能更好地去除污水中的COD,本文以此为基础通过正交实验进一步优化了两者复配的实验室参数,并对各个影响因子进行了分析。Nano-SiO2 was compounded with PFS in the flocculation experiment, and the result indicated the compounded flocculants done better than PFS in the remove of COD. The laboratory parameters were optimized by orthogonal experiment and the related factors were analyzed.
