QL-1000型二氧化氯发生器的杀菌效果及其影响因素的试验观察

The Experimental Observation on Killing Effect and Impacting Factors of Type QL-1000 Chlorid Dioxide Producing Instrument

目的 研究QL -10 0 0型发生器的杀菌性能及影响因素。方法 对该发生器产生的发生液产量、毒性、灭菌效果及影响因素进行了一系列的测定。结果 QL -10 0 0型二氧化氯发生器平均每小时产生二氧化氯 1 0kg。该发生器产生的发生液 10mg/L、 2 0mg/L的二氧化氯稀释液对大肠杆菌作用 10min ,12 0mg/L二氧化氯稀释液对枯草杆菌黑色变种芽胞作用 30min ,杀灭率均达到 10 0 0 0 %。该发生器对饮用水消毒作用 30min后 ,细菌总数与大肠菌群均符合饮用水卫生标准 ,温度对其有较强的影响 ,5 0 %的小牛血清对其有中度影响。结论 QL -10 0 0型二氧化氯发生器二氧化氯产量高 ,杀菌效果十分理想。因此 ,该设备应建议推广使用。

Objective In order to study the effect of killing microbe and impacting Factors of type QL-1000 chloride dioxide growing instrument.Methods The output,toxicity,killing effect and impacting factors of growing fluid produced by the instrument were mensured.Results Type QL-1000 chloride dioxide growing instrument produced chloride dioxide 1 0 kg/h,10 mg/L,20 mg/L diluent of growing fluid produced by this instrument offected to E.coli for 10 min,120 mg/L diluent to spores of B.subtilis var.niger for 30 min,killing rate was 100 00%.The sum count of bacteria and coli group all met the sanitation standard of drinking water after this in disinfected for 30 min by this instrument.Temperature had big influence to it,50%BSA had middle influence to it.Conclusions The output of chloride dioxide is high,the killing effect is very pefect.So this instrument can be used widely
