摘要和关键词

摘要: 文章研究牛粪发酵前后产物与酸性矿山废水（acid mine drainage，AMD）共处理过程及处理效果。结果表明，牛粪及发酵后产物（沼液）均对AMD具有不同程度的处理效果；处理前期，牛粪组R1和沼液组R2的pH值从3.07分别迅速升高到4.01和3.85，直至实验结束时pH值略有下降，分别达到3.91和3.47；酸度分别下降49.8%和44.83%。R1组Fe、Zn、Cu、Mn、Al等金属离子质量浓度分别下降72.34%、83.79%、96.48%、17.2%、46.89%；R2组Fe、Cu、Mn、Al质量浓度分别下降96.27%、61.40%、13.92%、48.19%。X射线衍射（X-ray diffraction，XRD）扫描结果表明2组实验对金属的去除主要以共沉淀为主，但在R1组中发现微生物可能对处理过程具有较大的推动作用。2组实验均对AMD具有较好修复效果，在利用养殖废水处理AMD具有很好的应用前景。

Abstract and Keywords

Abstract: In this paper, the co-treatment process and effect of products from cow manure before and after fermentation and acid mine drainage (AMD) were studied. The results showed that the cow manure and the fermented product (biogas slurry) had different effects on AMD. In the early stage of treatment, the pH values of cow manure group R1 and biogas slurry group R2 increased rapidly from 3.07 to 4.01 and 3.85, respectively, and decreased slightly to 3.91 and 3.47 at the end of the experiment. The acidity decreased by 49.8% and 44.83%, respectively. The concentration of Fe, Zn, Cu, Mn and Al in group R1 decreased by 72.34%, 83.79%, 96.48%, 17.2% and 46.89%, respectively. The concentration of Fe, Cu, Mn and Al in R2 group decreased by 96.27%, 61.40%, 13.92% and 48.19%, respectively. The result of X-ray diffraction (XRD) showed that co-precipitation was the main method for metal removal in the two groups of experiments, but microbe was found to play a significant role in promoting the treatment process in the R1 group. The two groups of experiments have a good effect on AMD repair, and have a good application prospect in the treatment of AMD by aqua- culture wastewater.
