| 摘 要： | 利用有机/无机复合型改性木质素絮凝剂MLF,处理抗生素类化学制药废水,并进行了絮凝条件的优选实验。结果表明,当抗生素制药废水的pH值为6.0,絮凝剂的用量为120 mg/L时,废水中CODCr、SS和色度的去除率分别达到61.2%、96.7%和91.6%。不同类型絮凝剂的对比实验结果表明,MLF处理抗生素类化学制药废水的用量少,絮凝性能明显优于聚丙烯酰胺(PAM)、聚合硫酸铁(PFS)、硫酸铝钾(PAS)和硫酸亚铁(FS)等絮凝剂。 |

| Abstract: | The sulfomethylated lignoamine was prepared with masson pine lignosulphate by Mannich reaction and sulfonation reaction.Then the organic-inorganic compound modified lignin-based flocculant could be obtained by further mixing with sodium aluminate solution.The modified lignin-based flocculant was adopted to treat the antibiotics pharmaceutical effluent.The flocculation conditions were optimized.The removal rates of COD_(Cr),SS and colourity of the effluent could reach 61.2%,96.7% and 91.6% respectively under such conditions as effluent pH value 6.0 and flocculant dosage 120 mg/L etc.Moreover,the comparison tests with various flocculants indicated that the flocculation performance of the modified lignin-based flocculant apparently prevailed over such flocculants as polyacrylamide(PAM),polyferric sulfate(PFS),potassium aluminium sulfate(PAS) and ferrous sulfate(FS) etc. |
| Keywords: | lignin modification sulfomethylated lignoamine flocculant pharmaceutical effluent flocculation |
