摘　　要：目的根据坑道水库储水真菌污染状况,对比观察二氯异氰尿酸钠和二氧化氯消毒剂对储水的防霉消毒效果,为战时或特殊情况下储水卫生保障提供依据。方法选择二氯异氰尿酸钠和二氧化氯作为坑道水库储水防霉消毒剂,进行实验室试验、现场模拟试验以及现场水库储水防霉消毒。结果根据储水量按有效氯20mg/L二氯异氰尿酸钠消毒储水,消毒后24个月余氯量为10.9mg/L。按5mg/L二氧化氯消毒储水,消毒后3个月二氧化氯浓度为0.01mg/L。结论二氯异氰尿酸钠在坑道环境中具有良好的稳定性,适宜作为坑道水库储水的长期防霉消毒。二氧化氯消毒储水,在坑道环境中3个月消毒效果好,适合坑道水库储水的快速短期消毒。Objective On the basis of the fungi pollution of the tunnel reservoir water storage,the effects of mildew resistance and disinfection on the water storage between sodium dichloroisocyanurate and chlorine dioxide disinfector were compared to provide a basis for water storage health security in wartime or under some special conditions. Methods Sodium dichloroisocyanurate and chlorine dioxide as mildew resistance disinfector for tunnel reservoir water storage were chosen to conduct laboratory tests,on-site simulation experiments and on-site reservoir water storage mildew resistance and disinfection. Results Disinfecting water storage with sodium dichloroisocyanurate containing a concentration of available chlorine 20 mg/L based on the water storage capacity,the remained chlorine was 10.9 mg/L in the 24th month after disinfection.Disinfecting water storage with 5 mg/L chlorine dioxide,the concentration of chlorine dioxide was 0.01 mg/L in the third month after disinfection. Conclusion Sodium dichloroisocyanurate which has a good stability in the tunnel environment is suitable for long-time mildew resistance and disinfection of tunnel reservoir water storage.Disinfecting water storage with chlorine dioxide which has an ideal disinfectant effect in tunnel environment in 3 months is suitable for rapid and short-term disinfection of tunnel reservoir water storage.
