| 摘 要： | 采用透射电镜法及光子相关光谱法对自制的氧化性聚硅酸铁(PSF)与聚合硫酸铁(PFS)进行微观表征,同时以254 nm的吸光度A(UV_(254))溶解性有机碳质量浓度c(DOC)、色度及比紫外吸光值A(SUV_(254))作为溶解性有机物(DOM)的检测指标,对PSF降低以上各指标与浊度去除效果及相关性进行研究.结果表明:PSF由很短的链节样物种及枝状结构组成,形态尺寸及分维数较大,并且较稳定;PSF具有良好的混凝效果,对浊度及色度的去除率超过95%,对A(UV_(254)),A(SUV_(254)),c(DOE)的去除率分别达到85%,80%,60%;用于评价PSF去除DOM性能的各指标间及其与余浊之间均具有良好的相关性.

| Abstract: | The characteristics of self-prepared oxidization poly-silicon-ferric sulfate(PSF) and poly-ferric sulfate(PFS) were explored with transmission electron microscope(TEM) and photon correlation spectra(PCS). Taking the absorbance at 254 nm (A(UV254)),mass concentration of dissolved organic carbon(c(DOC)),color,A(SUV254) as testing indexes of dissolved organic matters(DOM),the correlation between removal effect of PSF and turbidity was studied. The results indicate that PSF contains much short chains-like matte... |
