In the process of electrogalvanizing, the problems of wastewater treatment often bother the business owners, therefore, the electroplating wastewater treatment has become a big challenge for the galvanized enterprises. As the chemical substances produced after the electrogalvanization can pollute the water quality, once the galvanizing operation is finished, the effluent must be discharged immediately. Otherwise, it may easily affect the water source and even cause the water source to not be normal application. Galvanized pollution components and their complex, the main source of zinc from the galvanized products before the treatment of sewage, galvanized surface after the cleaning of sewage, and electroplating zinc generated in the process of waste generated, as a result of these The liquid mainly contains heavily polluted metal elements such as chromium, copper, nickel and zinc. Therefore, if the liquid is discharged without being strictly treated, it will greatly affect the environment. Electro-galvanized sewage treatment, due to people's reform and innovation, has evolved a variety of forms of treatment, such as: resin exchange reaction treatment, current decomposition treatment, chemical flotation, etc., can effectively plating Zinc sewage for immediate treatment. In the nineties of the last century, people learned through experimentation that the electroplating wastewater treated by the resin exchange reaction can not only curb the source of pollution, but also recycle precious rare metal materials therein. Next, Xiaobian the remaining sewage treatment technology for everyone Popular: A chemical precipitant treatment process. This method is by far the earliest human recognized sewage treatment method. After several decades of continuous development and technological innovation, it has become the most widely used and most effective sewage treatment technology until now. Some electroplating companies are also applying this method of sewage disposal. However, due to some technical problems, the process also has technical loopholes. For example, after a long period of sewage treatment by the process, the treated sludge and other debris can float to the surface of the water, Quality is still difficult to meet the standard stability. 2 chemical flotation method. The process of chemical and oxidation to neutralize, the use of gas floating physics theory of material decomposition, but due to the high content of some metal particles in the electrogalvanization process, coupled with the process of placing a lot of organic additives, so in The actual operation of the separation of pollutants is not complete, but, because of the operation steps and its cumbersome, so there will be some additional expenses. Until the world in the late nineties, the application of flotation method will be less and less. 3 electrolytic process. In medium and large screen enterprises, the most common application of this method, because the process without additives, simple operation, easy process, small footprint and other reasons, coupled with the high purity of the metal for the pollutant recovery, therefore, by The extensive use of industry and praise. However, due to the large flow of water in the process of the environment prone to large power consumption, the larger the amount of iron plate consumption occurs, therefore, the application of the technology companies are mostly medium and large enterprises. Summary: From the above treatment process, I believe that resin exchange reaction treatment method is more economical and practical, because of its simple processing steps, less expenditure, but also facilitate the recovery and application of scrap metal, therefore, are now electroplating pollution Widely used by enterprises. Earlier, I mentioned other sewage treatment process, although full of loopholes, but there are still some advantages, such as: Chemical precipitation method: the pollution caused by the electroplating process can be quickly restored within a certain period of time. Chemical Flotation: Although the treatment process is more complicated, but the content of contaminated particles can be reduced to a minimum. Electrolysis Process: The process of recycling of contaminants metal purity, work efficiency is also fast.
