摘要
从武汉焦化厂的活性污泥中筛选出4株具有稳定絮凝活性的菌株,对其中1株进行培养条件及废水絮凝实验研究。结果表明,该菌可产生高絮凝活性的最佳培养条件为:通用发酵培养基,初始pH值7.0,摇床转速80r/min,温度35℃,发酵时间72h。对高岭土悬浊液絮凝率达95.35%。同时在最佳培养条件下,该菌所产絮凝剂对多种废水净化效果明显。
Four strains of microorganisms from the activated sludge of Wuhan Coking Plant are able to produce a stable efficient bio-flocculation. One of the strains is chosen and its optimum culture condition and treatment of wastewater with produced bio-floceulation are studied. The results show that the optimum culture condition are： GCI culture, initiative pH 7.0, rotation speed 80r/min, culture temperature 35 ℃, culture time 72 h. The strain has produced a strong-activation flocculation with a flocculating rate of 95.35% against Kaolin clay suspension. And in the optimum culture condition the strains boasts obvious coagulation efficiency in wastewater treatment with produced bio-flocculation.
