Preparation and Properties of Modified Flocculant of Natural Vegetable Gum |
| |
Abstract: | By modifying natural vegetable gum,we obtained a sort of natural cationic flocculant.Its effect in wastewater treatment was studied.The sedimentation rate of fluoride-containing water reached 6 cm/min and the content of fluorine after treatment was less than 1 mg/L.The transmittance of a kind of treated activated sludge water reached 97% and its COD was reduced to 210 mg/L. |

Keywords: | vegetable gum flocculant modified fluoride-containing water |
