INNOVATIVE WASTEWATER TREATMENT TECHNOLOGY IN THE TEXTILE INDUSTRY

The relevance and novelty of the work is to develop a method of stabilization solid sodium ferrate by encapsulation, to obtain a «green» technology of wastewater treatment in textile enterprises. The article presents the study of the possibility using sodium ferrate in the technology of wastewater treatment from organic substances using the example of phenol in the textile industry. Here is shown the technology of obtaining encapsulated ferrate using hexane, ethylcellulose and paraffin. Within the study has been established the stability of the encapsulated sodium ferrate in air and alkaline solution and valuated the efficiency of using encapsulated sodium ferrate in the treated of the model solution from phenol, the efficiency of decomposition of phenol in a model solution by encapsulated sodium ferrate is estimated, the rate constants of the reaction of ferrate ions with phenol in an aqueous solution in the pH range from 6 to 10 are found. It is proved that with increasing pH of the solution, the degree of decomposition of phenol decreases. The pH value=6.5 is the most optimal for water purification from phenol using ferrate ions.
