<P>PROBLEM TO BE SOLVED: To provide a method which enables the removal of toxic substances dissolved or dispersed in exuded water from a least controlled landfill site at a low cost. <P>SOLUTION: In this method, a process for treating the exuded water comprises at least four processes: (1) a process for fixing or controlling the pH of the exuded water at 6-10, (2) a process for adjusting the concentration of iron ions and then dissolving it in the exuded water to generate ferric hydroxide colloidal particles, (3) a process for carrying out adsorption treatment using an anionic adsorbent or a neutral adsorbent, and (4) a filtration process using a filter medium with a cation exchange property. <P>COPYRIGHT: (C)2007,JPO&INPIT |
