摘　　要：再生水中富含微生物和各种有机质等物质,微生物大量生长繁殖容易引起水质恶化。通常采用投加消毒剂来控制微生物的增长,但消毒剂的投加会显著改变输送水的水质,进而通过水质的影响改变微生物、管壁腐蚀形态和结构。因此,研究了投加不同质量浓度(1、2、4 mg/L)的NaClO和ClO_(2)对再生水管网系统输送水的pH、DO质量浓度、电导率、阴离子质量浓度、氧化还原电位、总铁质量浓度和浊度变化的影响,研究结果为再生水厂消毒剂的选择提供了理论基础。The abundant microorganisms and each organic matters easily cause deterioration of water quality.Generally,the dosage of disinfectants is commonly employed to regulate microbial growth.However,the disinfectants dosage would change the transported water quality.And subsequently,the microorganisms,corrosion morphology of the pipe wall and structure would be changed.Therefore,the present research investigates the impact of varying concentrations(1,2,4 mg/L) of Na ClO and ClO_(2) on pH,dissolved oxygen(DO),conductivity,anion mass concentration,oxidation-reduction potential,total iron mass concentration and turbidity of the transported water.These findings offer a theoretical foundation for the selection of disinfectants in reclaimed water treatment plants.
