二氧化氯应用于二次供水安全消毒的静态研究
Static study on application of chlorine dioxide for disinfection of secondary water supply
摘要
Abstract
Chlorine dioxide ( ClO2 ) was adopted as a disinfectant for a secondary water supply. Under sim- ulated static experimental conditions, the effects ofClO2 dosage, NH3-N and CODM, concentrations, and pH on the attenuation of ClO2 and the formation of chlorate ( ClO3- ) and chlorite ( ClO2- ) were investigated, and the predictive models for the produced ClO3- and ClO2 concentrations were developed. The results showed that in the initial 4 h, the attenuation rate of ClO2 quickly increased with an increase in ClO2 dosage; the attenuation of ClO2 slowed down thereafter. ClO3- and ClO2- were produced immediately after adding ClO2, and their concen- trations approached stable after 4 h. An increase in ClO2 dosage resulted in elevated concentrations of the pro- duced ClO3- and ClO2-. The increase of NHa-N and CODM, concentrations and pH promoted the attenuation of CIO2 and the formation of ClO3- and ClO2- . The concentrations of ClO3- and ClO2- were increased by 6.49 μg/L and 8.32 μg/L in correspondence to an increase of NH3-N concentration from 0. 085 mg/L to 0. 585 mg/L, by 13.75 μg/L and 9.23 μg/L in correspondence to an increase of CODMn concentration from 1.13 mg/L to 3.13 mg/L, and by 13.28 μg/L and 10.01 μg/L in correspondence to an increase of pH from 6.49 to 8.45.关键词
