| 摘 要： | 选矿废水主要来源于有色金属矿山,具有水量大、悬浮物浓度高、重金属浓度高、有机浮选药剂浓度高等明显特征。选矿废水若直接排放,对环境的危害相当大。采用生物接触氧化法对模拟选矿废水进行了处理实验研究,考察了不同工艺条件对苯胺黑药、黄药及乙硫氮等浮选药剂去除效果的影响,结果表明:接触氧化反应器的最佳停留时间为8 h,进水最佳pH为6～7,葡萄糖投加量为0.1 mg/L时,降解效果达到最佳;此外,接触氧化反应器中微生物承受硫化物的浓度可达到120 mg/L。

| Abstract: | Flotation wastewater comes mainly from non-ferrous metal mines, with a large volume of water, high concentrations of suspended solids, heavy metals and organic wastewater flotation reagent .If flotation wastewater was discharged directly, it would make serious harm to the environment.We adopted bio-contact oxidation to research the ability of biodegradation and the effects of different operational conditions on removal of aniline aerofloat,butyl xanthate and ethyl thiocarbamate,respectively .The results indicated that the best removal efficiency could be achieved when the optimal retention time was 8 h,the appropriate ranges of pH was 6~7,the dosage of glucose was 0.1 g/L. Besides, the concentration of sulfide bearing reached 120 mg/L. |
