摘要: 利用以生物絮凝剂（1 g/L MBF-28）与化学絮凝剂（5 g/L PAC）复配后的复合絮凝剂CBF28C处理景观水体，考虑了复配比、投加量、pH和投加顺序对处理景观水的影响。实验结果表明：对于反应体系为100 mL景观水体，当MBF-28与PAC溶液复配体积比为3∶1，反应体系pH为7.0，1 mL 1% CaCl2作助凝剂，1.5 mL CBF28C时，其絮凝效果最好，其COD，色度，TN，TP的去除率分别为90.7%，54.1%、46.6%和51.5%。最佳水力条件为：快速320 r/min，快搅时间45 s，慢速80 r/min，慢搅时间100 s。并且得出了前10 min内絮凝率的反应关系方程式。

Abstract: Compounded flocculant CBF28C which combined by bioflocculant（1 g/L MBF-28）and chemical flocculants （5 g/L PAC） was used for landscape water treatment. The effects of mixture ratio， dosage， pH， and order of distribution of CBF28C dealing with landscape water were studied. The results show that when the volume ratio of MBF-28∶PAC=3∶1， pH of 7， 1 mL 1% CaCl2 as coagulant， and 1.5 mL CBF28C in 100 mL landscape water， the optimal the removal rates of COD， color， TN and TP were 90.7%， 54.1%， 46.6% and 51.5%，respectively. The optimal hydraulic conditions were as follows: quickly mixing speed of 320 r/min and time of 45 s， slowly mixing speed of 80 r/min and time of 100 s. Moreover， the kinetic equation of flocculation rate in 10 minutes was obtained.
