| 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. |
