| 摘 要： | 为解决某大型氟化盐厂高含氟废水达标排放的问题,采用石灰乳-聚合氯化铝两段法除氟工艺进行处理,确定了一段和二段的最佳工艺条件,同时对比了聚合氯化铝和硫酸铝两种絮凝剂的除氟效果.结果表明:一段工艺在将废水pH调节至12左右,即控制石灰乳投加量达到m(Ca2+实际)/m(Ca2+理论)为2.0～2.5,以及搅拌时间为30～5...

| Abstract: | In order to make the discharge of highly concentrated fluoride-containing wastewater meet the discharge standard at a large-scale fluoride salt plant,the lime milk-PAC two stage fluoride removing process has been conducted.The optimum process parameters of the first stage and second stage are determined.At the same time,the effectiveness of fluoride removal from the flocculants aluminum sulfate and aluminum sulfate are compared.The results show that the residual mass concentration of fluoride ion in wastewa... |
