低成本生物材料去除废水中铅的研究探讨

摘要

Lead in wastewater is one of hazardous pollutants in environmental. Finding an economic and effective method for removing Pb2+ from wastewater has been the hot point problem in water treatment researches. Low-cost bio-adsorbents are characterized by its simplicity of operation and good effectiveness on the removal of heavy metal ions. The application of bio-adsorbents for removing Pb2+from wastewater is summarized and discussed. The influencing factors and mechanisms of low-cost bio-adsorbents on the treatment of Pb2+-containing wastewater are analyzed. The problems and development trend of the research on bio-adsorbents at present are pointed out.%水体中的铅是环境的危险污染物之一,寻找经济、高效的废水中铅的去除方法是水处理研究的热点问题.低成本生物吸附剂具有操作简单、去除重金属离子效果好的特点,对当前低成本生物吸附材料在含铅废水处理中的应用情况进行了总结探讨,分析了低成本生物吸附剂处理含铅废水的影响因素及机理,探析了吸附剂再生的可行性,并指出了目前研究中存在的问题以及发展趋势.
