摘要
利用一株絮凝效果好的胶质芽胞杆菌所产的微生物絮凝剂进行了深圳市较具代表性电镀废水絮凝性实验。结果表明,微生物絮凝剂有较强的吸附作用,能降低电镀废水中重金属离子的浓度,对废水pH值有一定的调节作用。实验确定了处理综合电镀废水中重金属的条件,初步提出电镀废水的处理和回用工艺。
A treatment of electroplating wastewater from Shenzhen using microbial flocculants was studied.The microbial flocculants were produced by a strain of Bacillus mucilaginosus.Results showed that,after adding flocculant（FT）,the concentrations of heavy metal ions decreased and the pH values of wastewater samples increased.The control groups,using autoclaved flocculants and adjusting pH by NaOH solution,were set up;the important role of bacteria in the microbial flocculants as well as the superiority of the microorganism method over the chemical method was highlighted.The optimum technical conditions and good effects were established according to the results of orthogonal experiments.This study put forward the optimum technological conditions for the treatment and the recycle processes.
