【摘要】 采用不同的消毒剂对黄浦江原水进行试验,考察不同消毒剂量对水中营养基质及其组成组成部分所占比例的影响,结果表明:3种不同消毒剂对水中营养基质的影响存在较大差别,氯投量为1～4 mg/L时,对水中有机物的氧化作用可以分为高速反应和低速反应两个阶段,水中的AOC组成中AOC-NOX占优势.氯胺消毒时,管网中AOC变化幅度较小,出现高峰的时间比氯消毒滞后,低强度(0.038 mW/cm2)的紫外线照射对营养基质没有影响,中高强度(0.076 mW/cm2和0.153 mW/cm2)的紫外光照射后,水中营养基质随紫外光剂量的增大先降低后升高,AOC各组成部分中AOC-P17和AOC的变化一致,AOC-NOX变化较小.更多还原

【Abstract】 In order to investigate the effect of different disinfectants on the organic matter in drinking water,surface water from Huangpu River filtrated with MF membrane was studied.There was a significant difference among organic matter variations by chlorine,chloramine and UV.The oxidation of the organic matter in the water could be divided into high-speed and low-speed stages with the variation of chlorine dosage from 1 mg/L to 4 mg/L.AOC-NOX is the majority of the AOC composition in chloride water.AOC changes had a lesser extent and peak time lag than chlorine by chloramines disinfection.Irradiation by low-intensity UV(0.038 mW/cm2) had no effect on the AOC change.When AOC varied with the changes of UV dosage by high-intensity(0.076 mW/cm2 and 0.153 mW/cm2),the changes of AOC-P17 were consistent with AOC,and had no changes of AOC-NOX.更多还原
