The modification of technological scheme of wastewater cleaning from petrochemicals
M.M. Asadov Dr. in Ch. Sc. - Institute for Catalysis and Inorganic ChemistryThe paper analyzes and marks the advantages and shortcomings of up-to-date methods of wastewater cleaning from oil products. Combined usage of distillation, electro-coagulating methods enabling to water clean to the maximum admissible li-mits is justified. The modified technological scheme of wastewater cleaning from petrochemicals is proposed and the data before and after wastewater cleaning presented as well. The combination methods of distillation, electro-coagulation and adsorption in the technological scheme increases the cleaning efficiency of the wastewater heavily emulsified with oil products. In distillation phase, 10-15 % of petrochemicals is removed from the wastewater from overall volume of feed water. Afterwards, the cleaning of emulsified and suspended petrochemicals rises up to 80-85 % of total feed wastewater. Finally, the emulsified petrochemicals from the wastewater may be removed for 99 % via adsorption method.
