| 摘 要： | 筛选出一株针对屠宰废水有高效絮凝活性的微生物絮凝剂产生菌,并对其所产微生物絮凝剂D6进行单因子絮凝条件优化和正交试验优化得到最佳絮凝条件.絮凝条件包括:微生物絮凝剂D6投加量、pH、金属离子种类、1%CaCl2投加量.试验中发现碱性环境是微生物絮凝剂D6发挥絮凝活性的前提,表明微生物絮凝剂D6分子链的充分伸展对絮凝作用起决定因素,因此微生物絮凝剂D6的絮凝机理为吸附架桥作用.其最佳絮凝条件为微生物絮凝剂D6的投加量为25 mL·L-1,1%CaCl2投加量55 mL·L-1,pH为8.在最佳絮凝条件下,絮凝率为96.6%,浊度去除率为97.8%,SS去除率为92.6%.

| Abstract: | One bioflocculant-producing strain of high flocculating activity was screened for slaughter wastewater.The optimum flocculating conditions of bioflocculant D6 produced from this strain were obtained by single factor test and orthogonal design test.Flocculating conditions included bioflocculant D6 dosage,pH,kinds of metal ions and 1%CaCl_2 dosage.The study found bioflocculant D6 had flocculating activity under precondition of Alkaline environment,it indicated full extension of molecular chains of biofloccula... |
