【摘要】 通过对天然植物胶的胺基化阳离子改性 ,得到了一种天然絮凝剂。研究了改性植物胶絮凝剂处理废水的效果 ,处理含氟量为 2 5mg/L的废水沉降速度达到 6 5cm/min ,氟含量小于 1mg/L ;处理一种活性污泥 ,使水透光率达到 97% ,COD值降到 2 10mg/L。更多还原

【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.更多还原
