| titleOfInvention | It is a kind of can automatic liquefied polyaluminum sulfate chlorination alumina gel flocculant and preparation method thereof |
| abstract | The present invention relates to automatic liquefied polyaluminum sulfate chlorination alumina gel flocculants of a kind of energy and preparation method thereof, preparation method includes the following steps: 1) preparing the aqueous solution containing aluminum sulfate and aluminium chloride at room temperature, wherein aluminum sulfate: alchlor=1:3-1:6, molar ratio；2) aqueous sodium carbonate at room temperature, is added dropwise into above-mentioned aqueous solution under stiring, control basicity is 1.3-1.5, continues to stir 20-40min after being added dropwise；Then entire reaction system 3) is warming up to 40-80 DEG C, the reaction was continued 1-4 hours；Then it is down to room temperature, is centrifuged, obtains the automatic liquefied polyaluminum sulfate chlorination alumina gel flocculant of the energy and polyaluminum sulfate aluminum chloride flocculant aqueous solution respectively；Wherein the room temperature is 15-35 DEG C.The automatic liquefied gel flocculant of the energy of the invention be initially gel state, can turn to liquid after a couple of days with automatic liquid, be readily transported, easy to use. |
