| 摘要 |
<p>The disclosed invention relates to a method of disposing of mercury-containing wastewater containing mercury-complexing materials, comprising the steps of treating wastewater containing mercury ions with a strong oxidizing agent in a reaction chamber (2) to produce pretreated wastewater by removing an effluent stream of pretreated wastewater from the reaction chamber (2); and passing the effluent stream of pretreated wastewater through a column (6) packed with a mercury-selective adsorbent material to produce an effluent stream of wastewater having a reduced mercury content. The adsorbent material is a porous resin having immobilized mercury-selective chelating groups bound thereto. A particularly preferred adsorbent material is a crosslinked styrene-divinylbenzene copolymer having immobilized dithiocarbamate groups bound thereto.</p> |
