通过静态烧杯试验,分析了聚合硫酸铁( PFS)和硫酸铝两种混凝剂在不同投加量、pH值和助凝剂投加量条件下,对水中浊度和UV254去除效果的影响。试验结果表明：对于去除水中的浊度而言,PFS的最佳投加量为60 mg/L,最佳pH值为7,最佳助凝剂的投加量为0.1mg/L；硫酸铝的最佳投加量为50 mg/L,最佳pH值为6.5,最佳助凝剂的投加量为0.05 mg/L。对于去除水中UV254而言,UV254的去除率均随着混凝剂和助凝剂投加量的增加而增加,最佳pH值为6.5；作为混凝剂PFS的总体性能要优于硫酸铝。最后通过正交试验确定了当混凝剂为PFS时,影响强化混凝处理效果的各因素的主次顺序依次为：PFS投加量、pH值、PAM投加量,强化混凝的最佳实验条件为PFS投加量为60 mg/L,水体的pH值为6.5,助凝剂的投加量为0.10 mg/L。

Through static simulation test,the impact of polymeric ferric sulfate( PFS) and aluminum sulfate on the enhanced coagulation for the removal of turbidity and UV254 was studied under the condition of different co-agulant dosage,pH values and coagulant aid dosage. The experimental results showed that for the turbidity,the optimum value of coagulant dosage for PFS was 60mg/L,the corresponding optimal value of pH was 7,the co-agulant aid dosage was 0. 1mg/L,and for aluminum sulfate the dosage was 50mg/L,the pH was 6. 5,the coag-ulant aid dosage was 0. 05mg/L;for the UV254 ,the rate of UV254 removal increased with the increasing of the co-agulant dosage and the coagulant aid dosage,the optimal pH was 6. 5;as to be coagulant,PFS was better than aluminum sulfate. At last,through the orthogonal test,the order of the key factors for the PFS were as follows:the dosage of PFS,the pH value and the dosage of coagulant aid. And the optimized experiment conditions were that the dosage of PFS was 60mg/L,the pH was 6. 5 and the dosage of coagulant aid was 0. 10mg/L.
