目的 :了解缓释消毒剂对储水的消毒效果 ,为饮水消毒提供科学根据。方法 :于1998年 12月同时对某部 6个不同容积的储水池进行实验 ,投药后定期取样观察消毒效果。通过储存试验判定缓释消毒剂的性能是否稳定。检测方法按GB 5750 - 85进行。结果 :缓释消毒剂一次投药能持续消毒储水 18d ,余氯维持在 0 .0 9～ 2 .6 4mg·L 1,大肠菌群和细胞总数合格率在94 %以上。常温常湿条件下储存 18个月、2 4个月后 ,缓释消毒剂有效氯损失率分别为 14.6 %及2 8.4 %。结论 :缓释消毒剂用于储水消毒效果良好 ,性能稳定 ,作用时间长 ,适合平战时部队运水、储水的消毒 ,并可广泛用于井水、楼层水箱水、自备水源水的消毒
OBJECTIVE: To understand the disinfection effect of sustained-release disinfectant on water storage and to provide a scientific basis for disinfection of drinking water. Methods: In December 1998, six reservoirs of different capacities were tested at the same time. After disinfection, regular sampling was performed to observe the disinfection effect. Through the storage test to determine the performance of sustained release disinfectant is stable. Detection method according to GB 5750 - 85. Results: The single-dose sustained-release disinfectant could disinfect and store water continuously for 18 days. The residual chlorine was maintained at 0.09-2.46 mg · L 1. The passing rate of coliform bacteria and cells was above 94%. Storage at room temperature and humidity for 18 months, 24 months after release, the effective chlorine release rate of sustained release disinfectants were 14.6% and 2 8.4%. Conclusion: The sustained-release disinfectant has good effect in water storage and disinfection, stable performance and long acting time. It is suitable for the disinfection of water and storage water during the wartime. It can be widely used in well water, floor water tank, Disinfection
