  • 摘要: 反渗透海水淡化是解决水资源危机的一项重要技术。反渗透海水淡化水在饮用水生产过程中需进行消毒以解决微生物污染问题。采用次氯酸钙、二氧化氯和紫外线3种消毒方法，考察了反渗透海水淡化水和自来水的消毒效果，比较了对主要水质指标如pH、硬度和碱度的影响及余氯和余ClO2的衰减性。结果表明，二氧化氯消毒速率最快，次氯酸钙消毒对水质的影响最大，而紫外线的消毒效果最为稳定。可为反渗透海水淡化水的进一步利用提供依据。
    Abstract: Reverse osmosis (RO)seawater desalination is an important technology for solving the water crisis. The disinfection of the RO desalinated water is a critical step towards solving the problem of microbial contamination of drinking water. In this work,the disinfection effects of calcium hypochlorite,chlorine dioxide and ultraviolet rays (UV)were compared. The effects on water quality parameters including pH,hardness,alkalinity and the decay of residual chlorine and chlorine dioxide were then investigated. The results show that the disinfection rate of chlorine dioxide is the highest,while the disinfection effects of calcium hypochlorite on water quality parameters are maximal and the disinfection efficacy of UV is the most stable. These results will be helpful for further utilization of RO desalinated water.
