<p><P>PROBLEM TO BE SOLVED: To provide a method and equipment for recovering heavy metals etc. as metals as valuable substances from the liquid to be treated such as waste water containing them, by which only the metals to be recovered can be recovered as the metals as valuable substances from the liquid to be treated and in which a probability of containing impurities other than the metals to be recovered is low and, further, recovery rate is high and also the purity of the metals to be recovered is high. <P>SOLUTION: The process is characterized in that: the liquid to be treated in which the metals to be recovered are contained in the form of ions is allowed to flow into a reactor body; metal wires composed of a metal having an ionization tendency higher than that of the metals to be recovered are put in the reactor body; the metals contained in the liquid to be treated are deposited by the difference of ionization tendency on the surfaces of the metal wires; and then a collision member is allowed to collide with the metal wires to strip off the deposited metals from the metal wires and recover them. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
