以深海盐单胞菌V3a'(Halomonas sp.V3a')合成的新型微生物絮凝剂HBF-3对刚果红模拟染料废水进行脱色试验,探讨HBF-3加入量、溶液pH、温度对脱色效果的影响,并与活性炭和壳聚糖对刚果红染料的脱色效果进行对比.结果表明:增加HBF-3的加入量可以提高对刚果红溶液的脱色效果,HBF-3质量浓度为100 mg/L时对200 mg/L刚果红的去除率达83.7%;HBF-3对染料废水脱色效果受pH值的影响大,pH值在5.0～6.0时,HBF-3对刚果红溶液的脱色效果较弱,为41.1%左右;pH值在7.0～9.0之间变化时,脱色率稳定在88.7%左右;在10～70 ℃范围内絮凝率随温度变化而改变的幅度小.

A novel bioflocculant HBF-3 produced by deep-sea Halomonas sp.V3a' was used to remove Congo red from simulated dye wastewater.The effects of HBF-3 concerntration,pH and temperature on the dye removal were studied.With the increasing of HBF-3 concentration,the removal rate increased,when the concentration was 100 mg/L,the removal rate to 200 mg/L Congo red was up to 83.7%.In the range of pH 5.0-6.0,the removal rate was only 41.1%,but it kept about 88.7% in the optimal pH range of 7.0-9.0.Simultaneously,HBF-3 performed well over a wide temperature (10-70℃) range.In addition,the removal efficiency of HBF-3,active carbon and chitosan were also compared.
