摘要
以聚合氯化铝为混凝剂,采用高密度回流絮凝澄清池进行饮用水除氟试验。考察了原水水量、氟初始浓度、原水浊度、絮体回流比等因素对除氟效果的影响。结果表明:高密度澄清池具有良好的除氟效果,可使滤后水中氟浓度低于1 mg/L。当絮体回流点位于快速混合处时,回流比为50%时,能提高氟的去除率。
The test of fluorine removal from drinking water by high-density reflux flocculation clarification tank was done with poly-aluminum chloride（PAC）in this thesis.The effects of the original water inflow,initial concentration of fluorine,original water turbidity and flocs recycling ratio on the removal efficiency of fluorine were examined.The results showed that,the fluorine removal effect of high-density reflux flocculation clarification tank was excellent,the residual concentration of fluorine in post-treated water was lower than 1 mg/L.The removal rate of fluorine could be obviously raised with floc recycling point set at rapid mixed site and recycling ratio at 50%.
