| titleOfInvention | From sewage, reclaim the method for perfluorochemical |
| abstract | The present invention relates to a kind of method that reclaims perfluorochemical from sewage, belong to electrochemical techniques and field of Environment Protection, the method comprises the following steps: electric flocculation step, adopt electric flocculence, make the perfluorochemical in the aqueous solution or water-organic solvent mixed solution be adsorbed in the flco surface formation mud that electricity flocculation produces; Elution step, carries out the processing of organic solvent wash-out to the above-mentioned mud containing perfluorochemical, perfluorochemical is separated from mud, and generate concentrated perfluorochemical solution; Distilation steps, distill acquisition perfluorochemical solid and distillate to the perfluorochemical concentrate generating, and eluent using distillate as above-mentioned elution step. The Zn (OH) that electricity flocculation original position produces 2 Flco is high to perfluorochemical adsorption capacity, the rate of adsorption is fast, and recovery high concentration and low concentration perfluorochemical that can be from sewage be purified waste water simultaneously. Because electric flocculation treatment cost is low, sludge creation amount is few, large-scale application is feasible economically. |
