摘　　要：目的了解饮水消毒投放器投放含氯消毒剂对饮水消毒效果。方法采用理化分析法和细菌检验技术,对投放器投放消毒效果进行了观察。结果经该投放器定量投放含氯消毒剂溶液,在出厂水中游离氯稳定在0.3-0.7 mg/L范围,末稍水中游离氯稳定在0.05-0.4 mg/L;末梢水中总大肠菌群数100%符合生活饮用水卫生标准要求。结论使用该投放器投放含氯消毒剂对饮水消毒效果良好,可保持水中游离氯稳定,适合小型水厂应用。Objective To investigate the disinfection efficacy of ＂drop - in＂ - type drinking water disinfector using chlorine- containing disinfectant. Methods Physicochemical analysis and bacteriological examination method were used to observe disinfection efficacy of the ＂drop - in＂ - type disinfector. Results It was detected that the free chlorine content was stabilized at the range of 0.3 -0.7 mg/L in the water put out from the factory, while in the terminal water, the free chlorine content was stabilized at 0.05 - 0.4 mg/L, and the total coli - group count was 100% fulfilling the requirement of sanitary standard of the drinking water. Conclusion The ＂drop - in＂ - type drinking water disinfector using chlorine disinfectant has excellent disinfection efficacy. It can keep the free chlorine content stable in the drinking water. So this ＂drop - in＂ - type drinking water disinfector is suitable for small water factory.
