目的 评估奥润牌X型消毒康卫水机杀菌效果及试验中加压过滤法的应用。方法 用加压过滤法进行实验室人工污染水样、天然水样杀菌试验及杀菌效果影响因素分析。结果 奥润牌X型消毒康卫水机消毒作用 1min使人工污染水样中大肠杆菌 (5× 10 4～ 5× 10 5cfu/ 10 0ml)菌量下降至 0 / 10 0ml;消毒作用1min使天然水中的大肠杆菌量下降至 0 / 10 0ml;温度 (5～ 30℃ )、pH(6 .5～ 8.5 )、腐殖酸 (0～ 15mg/L)对水机杀菌效果影响不明显。结论 该水机具有较好的杀菌效果 ,可用于二次供水的家庭饮水消毒 ,加压过滤法可用于消毒水机杀菌效果的鉴定
Objective To evaluate the bactericidal effect of Aolun X-type disinfection Kang Wei water and the application of pressure filtration in the experiment. Methods Pressure filtration method was used to carry out laboratory artificial polluted water samples, natural water samples bactericidal test and bactericidal effect factors analysis. Results The results showed that the disinfection effect of Aolun brand X disinfection Kang Wei water machine reduced the amount of E. coli (5 × 10 4 ~ 5 × 10 5 cfu / 10 0 ml) in the artificial contaminated water sample to 0/10 0 ml for 1 min; The amount of Escherichia coli decreased to 0 / 10ml; temperature (5 ~ 30 ℃), pH (6.5 ~ 8.5), humic acid (0 ~ 15mg / L) had no obvious effect on the bactericidal effect of water. Conclusion The water has a good bactericidal effect, can be used for drinking water disinfection of the secondary water supply, pressure filtration method can be used for disinfection disinfection of the identification of water machine
