摘要
制备了无机-有机天然高分子复合絮凝剂PAC-CTS,并探讨了其组成、投加量以及废水pH对制药废水絮凝效果的影响。结果表明,当废水pH为6,复合絮凝剂组成中C为1/10,投加量为40 mg/L时,废水的色度和CODCr的去除率分别达到76.3%和47%。优于无机高分子絮凝剂PAC。可见,复合絮凝剂PAC-CTS兼有无机和有机絮凝剂的优点,是一种使用范围较广的新型絮凝剂。
The inorganic-organic composite flocculants PAC-CTS were prepared and used for treatment of pharmacy sewage. It showed that the composite flocculants were better than primary inorganic and organic flocculants. For pharmacy sewage more than 76.3% chromaticity and 47%COD were wiped off by 40 mg/L dosage of the flocculants with 1/10 weight fraction chitosan in the composite flocculant at about 6 pH value.
