| titleOfInvention | Method for using purified water sludge as raw material as arsenic and fluorine adsorbent |
| abstract | The invention is a method for preparing arsenic and fluorine adsorbents and an application thereof. The raw material used is sludge rich in aluminum and iron produced in the process of purifying water. The sludge is first washed by dilute acid, and the heavy metal oxide therein is dissolved and removed. Secondly, the aluminum and iron compounds in the sludge are dissolved into aluminum/iron ions by strong acid under microwave heating. After the acidified sludge is dehydrated, the filtrate is adjusted with a base to adjust the pH to form aluminum hydroxide and iron hydroxide precipitate. Finally, the dried aluminum and iron hydroxide precipitates are heated and activated to become an adsorbent for arsenic and fluorine. The adsorbent may be in the form of powder or granules, and the powder may be added to the clay to form a ceramic filter; the granular material may be used as a filler in other filter cavities, or may be directly put into water to apply fluorine. Adsorption. |
