微生物絮凝剂产生菌KJ-10的絮凝性能及絮凝成分分析
Flocculating property and ingredient analysis of the microbial flocculant-producing strain KJ-10
摘要
Abstract
A highly-efficient biofiocculant-producing strain KJ-10 was screened from refinery oily sludge,which was identified as Bacillus sp. In order to further investigate the flocculating property and ingredient of the strain, the treatment effect of KJ-10 on kaolin suspension and oily wastewater was measured and the thermal stability was studied. The flocculating ingredient by UV, IR, GC-MS and measurement its polysaccharide content was analyzed. The results showed that the bioflocculant which was produced by strain KJ-10 had 97.47％ of flocculation efficiency to gaolin clay suspension. It also had certain treatment effects on refinery oily wastewater, and the flocculation rate was up to 94.96％ , the removal rate of petroleum and COD could reach to 50.75％ and 45.23％, respectively. It had good thermal stability, and its flocculating activity could keep above 81％ after being heated at 90℃ for 30 min; the bioflocculant with the polysaccharide structure, and its polysaccharide content was 54％. It was probably composed by glucose and rhamnose.关键词
