单过硫酸氢钾复合盐作为生活饮用水消毒剂的安全性探讨

摘要/Abstract

摘要： 单过硫酸氢钾复合盐作为一种较为安全、高效的氧化剂和消毒剂,已广泛应用于饮用水消毒、水产养殖和环境消毒等领域。本文通过分析该复合盐的理化性质、作用原理、消毒效果、影响因素和生成的消毒副产物类型等最新文献研究进展,发现其可有效去除饮用水中的醇类、醛类等小分子有机物以及微生物和藻类。但当水中卤化物浓度较高时,生成的卤代烷烃等消毒副产物浓度有超过GB 5749—2022《生活饮用水卫生标准》的风险。今后仍需深化该复合盐在饮用水领域的基础研究与应用实践,加强其应用于生活饮用水消毒的监测与风险评估,依法依规完善相应的卫生监督和管理制度。

Abstract: As a relatively safe and highly efficient oxidant and disinfectant,potassium monopersulfate compound has been widely applied in the fields of drinking water disinfection,aquaculture and environmental disinfection. This paper analyzes the research progress of latest literature on basic physical and chemical properties of potassium monopersulfate compound for disinfection,the disinfection principle,disinfection efficacy and influencing factors,and the disinfection by-products. It is found that potassium monopersulfate compound could effectively remove the small molecular organic substances such as alcohols and aldehydes,as well as microorganisms and algae in drinking water. However,some halogenated hydrocarbons and halogenated substances are also produced in the disinfection process,resulting in risk of exceeding the Standards for drinking water quality（GB 5749-2022）. The basic research and application practice,monitoring and risk assessment of potassium monopersulfate compound in drinking water disinfection should continue to be enriched and deepen. According to the laws and regulations and standards,the hygiene supervision and management systems should be improved.

Key words: Potassium monopersulfate compound, Drinking water, Disinfection, Safety
