摘　　要：研究了一种稳定型含氯消毒剂的消毒特性及其在水中的稳定性。发现所用稳定型含氯消毒剂的消毒能力比次氯酸钠弱,但消毒作用持续时间长,在水中的半衰期长达9d,而次氯酸钠只有2h,经有效氯为2mg/L的稳定型含氯消毒剂消毒后的水,可在开放条件下抑菌时间长达12d,而次氯酸钠不到2d。稳定型含氯消毒剂可广泛应用于饮用水的消毒。This paper investigates the disinfection property and stability of a stable chlorine disinfectant in drinking water. It is found that the disinfection property of the disinfectant is weaker than that of a hypochlorite, but it has a much longer duration. The stable chlorine disinfectant has a half life of 9 days in water, but it was only two hours for hypochhorite. The water disinfected by the stable chlorine disinfectant with an effective chlorine content of 2 mg/L restrained the growth of bacterium for 12 days in an open air condition, but the hypochlorite less that two days. It is believed that the stable chlorine disinfectant has a wide application in drinking water disinfection.
