摘　　要：研究了含硼聚硅酸氯化铁 (PFSCB)的应用性能。模拟废水的混凝实验 ,结果表明 :在pH=7～ 10、投药量为 30～ 10 0mg/L时 ,经PFSCB处理后废水的剩余浊度仅为 1 6～ 4 0度 ;用PFSCB处理废纸造纸废水 ,其浊度、色度和CODcr去除率分别为 99 4 %、93 8%和 96 4 %。PFSCB的混凝性能优于聚硅酸氯化铁、聚合硫酸铁和氯化铁。Application of polymeric ferric silicate-chloride containing boron(PFSCB) was investigated. The experimental results show that the remaining turbidity in the simulative wastewater treated by PFSCB decreases to 1 6-4 0 NTU when pH of the wastewater is 7-10 and dosage of PFSCB is 30-100 mg/L.When wastewater from regenerated paper making is treated by PFSCB, the turbidity,color and CODcr removal ratios are 99 4%,93 8% and 96 4% respectively .The flocculation ability of PFSCB is superior to that of polymeric ferric silicate-chloride,polymeric ferric sulfate and ferric chloride.
