| Title of the article | Wastewater treatment of heat station from metal ion |
| Abstract. | In this article the study of industrial wastewater treatment is described. Preferably, it relates to the purification of industrial waste waters from various metal ions Most suitable methods for this purpose are chemical. These methods are uneconomical and difficult to implement. This article describes an electrochemical method of cleaning. In this method soluble anodes are not used, as in electrocoagulation method. In the described method the increase in pH due to water electrolysis is used. This increase in pH occurs in the cathode region. This value of pH in the range of 9.8 units. Most metal ions are hydrated and coagulated under these conditions with the formation of the precipitate. Removal of this sludge provides treatment of wastewater from metal ions. The results of field studies are shown in the example of industrial wastewater treatment. The most difficult is the removal of nickel ions. The remaining metal ions are removed enough. Also a diagram of the experimental process is resulted. There are three stages of purification. All three steps are electrochemical. The design of electrode systems at these levels is described. The authors' conclusions is that this method provides the possibility in principle for waste water from metal ions with advantages in relation to other methods. |
