【摘要】 介绍了利用络合原理复配的高效除氟剂—改性聚铁 ,结合传统的钙盐沉降法工艺处理高氟废水的测验。在实验条件下 ,氟与改性聚铁 ,氯化钙形成多元络合物复合盐 ,然后用聚丙烯酰胺絮凝。废水中氟浓度下降至 1 0 /mg· L- 1 以下 ,排放废水含氟量达到国家标准更多还原

【Abstract】 The moderate technological conditions of fluoride removal from the high fluoride-containing wastewater by coagulation and precipitation are studied.Under the experimental conditions,fluoride removal agent,calcium hydroxide,calcium chlorite and coagulates with polyacrylamide.The concentration of wastewater can be reduced to below 10/mg·L -1 and meets the drainage standard.更多还原
