摘要
介绍了含砷废水的危害和处理技术发展现状,分析了传统除砷工艺技术的特点及局限性。对吸附法处理含砷废水进行了重点阐述。结果表明,吸附法是同时实现废水除砷和砷资源回收利用的有效技术,而吸附法处理含砷废水的关键在于吸附剂的性能。因此为应对新的生活饮用水水质标准的要求,开发廉价、高效、稳定的新型除砷吸附材料将是重点关注的研究方向。
The hazard of arsenic-bearing wastewater and the present situation concerning the technology of its treatment are introduced. The characteristics and limitations of various traditional arsenic removing technologies are analyzed. The application of adsorption method to the treatment of arsenic-bearing wastewater is expounded emphatically in detail. The results show that adsorption method is effective on arsenic removal, as well as on the recycle of arsenic from arsenic-bearing wastewater,and the efficiency depends on the characteristics of the adsorbents. To answer for the requirements of new water quality standard, new materials with low-cost and highefficiency and strong-stability should be mainly developed in future study.
