The distribution, trihalomethane formation potential ( THMFP ), UV-Vis and FTIR spectra of organic fractions in the secondary effluent were examined. 考察了二级处理出水中有机组分的组成分布、三卤甲烷(THM)生成势、紫外光谱和红外光谱。
The influence of extracted and commercial humic acid on trihalomethane formation was studied, and the characteristics of humid acid were analyzed. 以提取腐殖酸和商品腐殖酸为对象,研究了不同腐殖酸对加氯消毒后三卤甲烷(THM)生成量的影响,并对腐殖酸特性进行了分析。
The result shows that the humic acid extracted in Yichun produces more trihalomethane with higher formation rate and higher halogenated activity, as compared with the humic acid extracted in Songhuajiang and commercial humid acid. 结果表明,伊春腐殖酸比松花江腐殖酸和商品腐殖酸具有更高的三卤甲烷(THM)生成量、生成速度和更高的卤代活性。
The organics with small molecular weight and unsaturated double bond content are always the main precursors of disinfection by-product, which leads to the higher trihalomethane formation with the Yichun humic acid than the Songhuajiang and commercial humic acid after chlorine disinfection. 小分子质量和含不饱和双键的有机物通常是消毒副产物的主要前体物,因而伊春腐殖酸加氯消毒后的三卤甲烷(THM)生成量比松花江腐殖酸和商品腐殖酸高。
Synergistic Pretreatment of Permanganate and Chlorine to Control Trihalomethane Formation 高锰酸钾与氯协同预处理控制三卤甲烷(THM)的生成
