A METHOD FOR ACCELERATING ELECTROCHEMICAL PHYTOREMEDIATIONOF WASTE WATER FROM HEAVY METAL IONS WHEN EXPOSED TO PHYTOSORBENT PLANTS BY PHYSICAL FIELDS

Abstract

The article is devoted to the problem of increasing the efficiency of purification of natural and waste waters from heavy metal ions by the method of electrochemical phytoremediation. The results of studies on the management of phytoremediation processes by exposure to higher aquatic plants by external physical fields (constant magnetic field, combined exposure to a constant magnetic field and geomagnetic field, constant magnetic field and weak electric (j) fields) are presented. The ef-fect of accelerating the sorption of heavy metal ions under the influence of external physical fields on plants of Lemna minor has been experimentally confirmed. Rational conditions for controlling the processes of selectivity and increasing the rate of electrochemical phytoremediation and the completeness of the extraction of heavy metal ions from contaminated waters using higher aquatic plants are determined. A flow chart of the treatment of wastewater from heavy metals by the phytoremediation method using a biopond / settler populated by higher aquatic plants is proposed.
