农药及制药废水的处理技术及研究进展

Progress in the Treatment of Pesticide and Pharmaceutical Wastewater

随着我国工业的发展,药物的广泛使用,致使废水中的药物日益增加,污染问题逐渐加重。首先介绍了利用电芬顿法和多孔磁性铜铁氧体对农药中的杀虫剂降解的研究,然后对制药废水的来源、危害及目前常用的处理技术进行了综述。传统技术对制药废水的降解效果不佳,而新出现的技术,包括光化学基因降解法、单色光降解法、紫外光/过氧化氢降解法、臭氧化处理法、活性炭过滤法、纳米复合材料吸附法和生物处理法,降解效果较好。对上述各方法的机理、研究进展、优缺点进行了综述,同时展望了制药废水处理技术的发展方向和趋势。

As the development of the industry in our country and the increasing use of drugs,which enter into the water continually,the drug pollutants gradually aggravate.Firstly,it made use of electric Fenton reaction and porous magnetic copper ferrite to degrade pesticides in the wastewater.Then,the sources and the harmfulness of the pharmaceutical wastewater and the present commonly used treatment technology were summarized.It was found that the traditional technology was poor to degrade the pharmaceutical wastewater,so many new technologies emerge at the right time.These treatment technologies include photochemical gene degradation,monochromatic light degradation,ultraviolet light/hydrogen peroxide degradation,ozonation treatment,activated carbon filter method,nanocomposite adsorption method and the degradation of biological treatment. It is excellent for the effect of these new technologies to degrade the pharmaceutical wastewater.The mechanism,research progress,advantages and disadvantages of the above methods are reviewed.At the same time,it prospects the development direction and the trend of treatment technology to degrade the pharmaceutical wastewater.
