In this article, the specificity of wastewaters formed at electroplating plants and problem of its treatment is considered. The purpose of this research is to suggest the technological scheme of wastewater treatment, for one of the typical electroplating plants. Standard research methods were used: gravimetrical, photometrical and fluorimetrical methods of liquid analysis to achieve this goal. This article presents the method of electroplating wastewater treatment, based on chemical precipitation, including addition of the various reagents for removing heavy metals from the effluents. Because of the laboratory research, the effects of pollutants removal are 91% (total iron) and 94.6% (suspended solids). These effects were achieved by the technological scheme that includes averaging and mixing several technological effluents, their chemical precipitation with NaOH, Ca(OH)2 and flocculant during an hour.
