Fluorine-containing wastewater composite defluorinating agent and preparation method and application thereof |
| abstract |
The invention discloses a fluorine-containing wastewater composite defluorinating agent and a preparation method and application thereof. The composite defluorinating agent comprises: humic acid-CaO-polyaluminium chloride-water composite material. The preparation method comprises the following steps: (1) dissolving humic acid in saturated calcium hydroxide solution, and uniformly stirring; (2) adding polyaluminium chloride while stirring; (3) adjusting the pH value, and then carrying out solid-liquid separation; (4) and washing, drying and crushing the separated solid to obtain the fluorine-containing wastewater composite defluorinating agent. The application is as follows: adding the prepared composite defluorinating agent into a fluorine-containing wastewater treatment device, fully stirring to enable the composite defluorinating agent to react with fluorine ions, adding 1 per mill of anionic polyacrylamide solution until the mud-water separation is obvious, and detecting the fluorine ion content of the supernatant after standing. |
