摘　　要：Antimony ore dressing wastewater was treated by using Bacillus sp. and the influences of treatment time, temperature, inoculation size, and pH value on Sb removal effect were explored. The results showed that the best removal efficiency of Sb in mineral processing wastewater could reach 99.75% in 4 d under the optimum conditions of 30 ℃, microbial inoculated quantity 5%, and pH value at 2.0. After the treatment, the concentration of Sb in wastewater was reduced from 122.21 to 0.30mg/L, which was lower than the local industrial wastewater discharge standard of0.50 mg/L.利用某芽孢杆菌属微生物(Bacillus sp.)对锑矿选矿废水进行了处理。研究微生物的接种量、作用时间、温度、体系pH值等对废水中Sb的去除效果的影响。结果表明:作用时间4 d微生物接种量为5处理体系pH为2最佳处理体系温度为30时,效果最佳,对废水中Sb的去除率达到99.75%,处理后废水中Sb的浓度由122.21 mg/L降低至0.30 mg/L,出水Sb浓度低于湖南省地方标准排放限值0.50mg/L。
