| titleOfInvention | A kind of suspended liquid Fe-contg complex reagent and preparation method thereof and the method for efficiently removing selenate in water removal |
| abstract | The method that the present invention discloses a kind of suspended liquid Fe-contg complex reagent and preparation method thereof and efficiently removes selenate in water removal, belongs to water-treatment technology field.The present invention includes three steps of following sequence: the first step prepares suspended liquid Fe-contg complex reagent using zeroth order iron powder, water, hydrogen peroxide and hydrochloric acid；Second step removes selenate using suspended liquid Fe-contg complex reagent, and the suspended liquid Fe-contg complex reagent obtained containing solid phase, gel phase, liquid phase is integrally added in the water to be processed containing selenate；Third step is separated by solid-liquid separation.The invention has the advantages that the preparation of iron content complex reagent is simple, low raw-material cost；Iron content complex reagent contains there are many reduction activation component, and selenic acid is promoted to remove by reduction approach, has gel phase abundant, high with solution mass-transfer efficiency, has both absorption and flocculation；It is efficient to remove selenate, still can effectively work when the anion such as high concentration sulphate coexist, be particularly suitable for selenium-containing wastewater with high salt, it is environmental-friendly, it is without secondary pollution. |
