Application of Nanotechnology in Wastewater Treatment
Journal Title: Nanoscience and Nanotechnology - Year 2017, Vol 1, Issue 1
Abstract
Because the current social water pollution is serious, and the conventional method cannot eff ectively manage all types of water pollution, and its single effect cannot be satisfactory, we must seek new and effective treatment. The paper is a comprehensive review of the best practices of the conventional wastewater treatment method with reference to the experiments and research results of nanotechnology in sewage treatment. Comparison of nanotechnology can be compared with conventional methods to make the particles have a special function, and some special performance just in the sewage treatment medium to a good effect: the depth of the catalytic method can be effective in the decomposition of many types of organic pollutants such as halogenated hydrocarbons Class, chlorinated phenols, cyanide, various organic acids and can handle metal particles; adsorption method for the water heavy metal pollution treatment costs less, simple and widely used, nanofiltration membrane can replace the adsorption and electrochemical methods, Pulping and precipitation are one of the most effective methods for the treatment of colloidal wastewater. It can effectively reduce the turbidity and chroma of waste water, remove a variety of macromolecular organic matter and some heavy metal ions ( Mercury and lead); organic / inorganic composite nanoparticles with its excellent inorganic materials, light, electricity, magnetic and other properties, organic materials, excellent processing performance, biocompatibility, for many difficult to deal with water pollution control, which has a corresponding method, can be simple and effective to solve the problem. The application of nanotechnology in water treatment has shown a broad prospect, but needs further research and improvement.
