摘　　要：为探究新型钛铁复合药剂的微絮凝强化过滤性能,通过微絮凝滤柱模拟试验制备了聚合硫酸钛(PTS)、碱化度分别为0.5、0.75、1.0的钛铁复合药剂(PTFC),考察出水浊度、颗粒数、溶解性有机物、过滤周期等指标,对比分析不同药剂的助滤效能;结合有机物荧光特性、亲疏水性有机物去除情况,探究有机物去除机制。结果表明,紫外可见光谱及傅里叶红外光谱表征发现PTFC中Fe和Ti产生了多种高聚态化合物,PTFCb0.75助滤剂对浊度、颗粒数、溶解性有机物等显示出高效的去除效果;通过LO-COD检测说明了PTFC能够很好地降解大分子有机物,吸附小分子有机物。To explore new ferrotitanium composite reagents micro flocculation strengthening filtration performance influence,polymeric titanium sulfate(PTS),basicity were 0.5,0.75,1.0,ferrotitanium composite reagent(PTFC)were prepared through micro flocculation filter column simulation experiment.The water turbidity,the number of particles,the soluble organic matters,and filtration cycle index were examined and the different reagents leaching efficiency were analyzed.Combined with the fluorescence characteristics of organic matter and the removal of hydrophilic and hydrophobic organic matter,the removal mechanism of organic matter was explored.The results showed that several high polymeric compounds were produced in Fe and Ti of PTFC under characterization by UV-Vis and FT-IR spectroscopy.The PTFCb0.75 filter aid showed high removal efficiency on turbidity,particle number and dissolved organic matter.The LO-COD test showed that PTFC could degrade macromolecule organic matter and adsorb small molecule organic matter well.
