摘要
利用电感耦合等离子发射光谱仪(ICP),测定西安市江村沟垃圾填埋场渗滤液不同处理阶段水(泥)中的金属离子种类及含量。结果表明,垃圾渗滤液不同阶段的水(泥)中含的19种金属离子的浓度变化有升有降,且变化幅度不一致,原因是微生物生长利用不同、生物吸附与解吸程度不同、酸碱度变化形成沉淀或溶解程度不同和填埋场垃圾组成时空不均等。实验检测的是浓缩液的液相部分,重金属离子可能大量存在于浓缩液固相中,着重研究浓缩液固相中重金属离子,是以后浓缩液资源化利用的可行性研究方向。
Using inductively coupled plasma emission spectrometer（ ICP）,landfill leachate of Xi ＇an Jiang village different processing stages water（ mud） kinds of metal ions and content were determined.The results show that the garbage leachate in the different stage of water（ mud） contains 19 kinds of mixed metal ion concentration changes,inconsistent,and changes in reason is microbial growth by using different,different biological adsorption and parsing,pH change precipitation at different levels or dissolved and landfill waste of time and space is not equal. In this experiment,the liquid phase of the concentrate is detected,and heavy metal ions may exist in the solid phase of the concentrate,it is a feasible research direction to study the concentration of heavy metal ions in concentrated solution.
