PROCESS FOR TREATMENT OF A FLUID |
摘要 |
<p>A process comprised of substantially separate kinetically-controlled steps for continuously treating a fluid comprising at least one chemical contaminant. The process comprises the steps of: (i) contacting the fluid with a particulate adsorbent material; (ii) allowing the adsorbent material to adsorb the chemical contaminant to produce a substantially purified fluid and a partially loaded contaminant-carrying adsorbent material where the extent of loading depends on the kinetic requirements of the overall process; (iii) separating the contaminant-carrying adsorbent material from the substantially purified fluid; (iv) contacting the contaminant-carrying adsorbent material with an aqueous slurry of a metal oxide powder in the presence of an electron acceptor and electromagnetic radiation in at least one of ultraviolet and visible regions; (v) allowing the contaminant to decompose to form a product which is dissociated from the contaminant-carrying adsorbent to provide a regenerated adsorbent material; (iv) separating and recycling the regenerated adsorbent material to Step (i); and (vii) recycling the aqueous slurry to Step (iv). The process may be used to remove contaminants from and thereby purify fluids such as water, off-gases from air stripping processes and chimney gases.</p> |
