The application of nanotechnology in water pollution treatment

Nowadays, the situation of water pollution in the world is becoming more and more serious, which has aroused widespread concern. The traditional water pollution treatment technology mainly includes membrane separation method, catalyst treatment and adsorbents treatment, and the nano water pollution treatment technology has greater advantages than the traditional technology. Such as nano-photocatalyst, nanofilter membrane, nano adsorbents. For example, MOF materials, inorganic membranes, polymer membranes, and nano-adsorbents composed of iron metal oxides and transition metal oxides.In recent years, with the continuous development of nanotechnology, the nanomaterial technology mentioned in the above article has shown excellent performance in treating pollutants or impurities that may exist in water.These three methods are the direction of deep research. This paper mainly expounds their respective advantages and general performance, and selects examples of related technologies to discuss. On this basis, by analyzing the relevant principles and data of the research examples cited in the article, we can provide certain ideas and pioneering ideas for future research.
