<p>PROBLEM TO BE SOLVED: To provide a method for efficiently separating and removing heavy metals from a waste liquid containing the heavy metals produced at the time of producing an easily polymerizable substance. SOLUTION: When the waste liquid containing organic substances and the heavy metals is treated, an alkaline compound is used in a combustion process for combusting the waste liquid while purifying a combustion exhaust gas by liquid-contact and a flocculant is added into a liquid in a cleaning tank for cleaning the exhaust gas generated from the combustion process, and the heavy metals are flocculated, separated and removed.</p> |
