Abstract

The invention refers to process for purification of waste waters from heavy metals ions.Summary of the invention consists in, that it is proposed a process for waste water purification from heavy metals ions by means of chemical reagent-reducers used at pH 6...8 in the following ratio, mol/L:The results consists in increasing the degree of waste water purification and in decreasing the materials and power consumption for carrying out the purification process.
