摘要

通过扫描电镜和能谱分析（Scanning Electron Microscope and Energy Dispersive Analysis

SEMEDS）对饮用水活性炭工艺出水中的颗粒物进行成分组成分析，考察颗粒物的分布特征及其中主要元素的概率分布，并分析活性炭工艺出水颗粒物中单元素的可能组成形态。结果表明，活性炭进出水中颗粒物所含元素较多，其中以Ca、Fe、Al 、Si 、C、O为主，且非金属元素的比例明显高于金属元素；颗粒物微观形态丰富，形状多以不规则为主，球形体、絮状集合体和棒状集合体相对较

Abstract

Scanning Electron Microscope and Energy Dispersive Analysis (SEMEDS) were used to study the elements of particles in drinking water treatment effluents

to conduct the distribution characteristics of particles and distribution probability of main elements

and to analyse the possible structure of individual element in the Granular Activated Carbon(GAC) effluents particles. It was indicated that there were more elements in particles at GAC inlet and outlet

in which the major elements were Ca、Fe、Al 、Si 、C、O. And the concentration of nonmetal elements was absolutely higher than that of metal elements. The shapes of particles were various

in which most of them were irregular and very few were baculiform

spherical or flocculent. The molar ratio of (C+O) to (Ca+Fe+Al+Mg) in particles had a wide range

from 1.0 to 40

in eight samples

in which ratios of two samples were 1.0-3.0 and five were over 7.0.
