玉米芯为碳源实现酸性矿山废水生物处理

引入了一种新的碳源——玉米芯，对SRB法处理酸性矿山废水进行了更加深入的探索，分析了各种参数条件对s暖一还原效果的影响，确定了常温下这种碳源所需要的最适宜工况条件，探讨了硫酸盐矿山废水的水质资源化问题，并对山西矿山废水的生物治理进行了可行性实验验证。实验证明，玉米芯为碳源时，矿山废水中SO^2-4的出水值可达221．1mg／L，金属离子的浓度也都达到了生活饮用水的质量标准，所以玉米芯可作为酸性矿山废水资源化生物处理的合适有效碳源。

Biological Treatment for Acid Mine Drainage by Using Corncob as Carbon Source

The corncob is used as a kind of new carbon source and some researches on the acid mine drainage treatment with SRB are conducted.The authors analyse the changes of SO 2- 4 following with the parameters and determine the best conditions for the carbon source.Some researches on one kind of Shanxi acid mine drainage are conducted at last so as to prove the conclusions.From the experiment we can conclude that under the normal temperature,when the carbon source is supplied by corncob,SO 2- 4 in the implemented water is about 221.1mg/L,many heavy metal hydroniums in the drainage can become sulfide subside together with sulfur and the water quality of the treated drainage can meet the standard of drinking water.So the corncob can be used as a kind of economic and feasible carbon sources in the treatment.
