摘　　要：目的　了解我军部分坑道现有储水的水质状况 ,评价坑道储水施用控制释放饮水消毒剂 (CRPD型 )的消毒效果 ,为饮水消毒提供科学依据。方法　通过对海防某部及工程兵某部坑道储水情况的全面调查 ,结合对该部分储水施用控制释放消毒剂前后水质检验的结果 ,研究观察目前坑道储水在长期储存过程中的水质变化情况及评价该型消毒剂的消毒效果。检测方法按GB5 75 0 - 85进行。结果　大部分坑道储水感官性状、理化指标基本符合卫生要求 ,但微生物污染严重。采用控制释放饮水消毒剂对坑道储水进行消毒处理 ,实验室与现场消毒结果表明 ,一次投药至少能持续消毒 1 0 0d ,水中余氯维持在 0 2 0～ 3 1 5mg/L ,细菌总数和大肠菌群合格率达 1 0 0 %。 结论　CRPD型控制释放饮水消毒剂对储水消毒效果良好 ,性能稳定 ,药效长 ,易维护 ,是坑道储水消毒的有效方法。Objective To know about and master the present tunnel stored water quality of our army.To present the tunnel water disinfecting effect by making use of controlling-released potable water disinfectant (CRPD) so as to offer scientific evidence to the potable water disinfection. Methods Through the overall investigation on the stored tunnel water situation of some coast defense ministry and some engineering ministry,to report the changed water quality of the present stored tunnel water during the long-term storage and the disinfecting effect of this disinfectant with the help of the water quality test report before and after using the controlling-released disinfectant.The survey was conducted according to the GB5750-85.Results Large parts of the sense perception properties and physical-chemical index of the stored tunnel water basically accorded with the sanitation requirement.but the problem of microbe contamination was very serious.Controlling-released potable water disinfectant was applied to the stored tunnel water.The disinfecting results from the library and the scene showed that the disinfectant could continuously disinfect water 100?d.the surplus chlorine was maintaining 0.20-3.15 mg/L,the disinfectant could continuously disinfect of germ and the coliform bacteria was 100%.Conclusion The disinfecting effect of the CPRD controlling-released potable water is good for the water-storage with stable quality long efficiency,easily being maintained,which is an appropriate and efficient way of solving the quality problem of the stored tunnel water.
