我们在试验中发现用铜器装的生水,大肠菌群检出很低,甚至检不出,为证实铜器装水是否对细菌有灭活作用,在这方面进行了试验观察。 一、试验方法:用无菌瓶采集水样回试验室先做大肠菌群,再将水样倒入铜器中(黄铜器)室温放置过夜,再做大肠菌群测定,观察水中大肠菌群的变化情况。测定方法按生活饮用水水质检验方法操作。 二、结果与讨论:用铜器贮存不同水,大肠菌群检出都低,其中井水原有的大肠菌群浓度为90～>23800个/L,放到铜器中过夜后,下降率为96～100％;河水原有大肠
We found in the experiment with raw water installed in bronze, coliform detection is very low, and even undetectable, in order to confirm whether the bronze water inactivation of bacteria, in this regard, the experimental observation. First, the test method: aseptic bottles to collect water samples back to the laboratory first coliform bacteria, and then the water sample into the bronze (brass) overnight at room temperature, then do coliform determination, observation of coliform Group changes. Measurement methods according to drinking water quality control methods of operation. Second, the results and discussion: Copper storage of different water, coliform detection were low, of which the original well water coliform concentration of 90 ~> 23800 / L, into the copper overnight, the rate of decline was 96 ~ 100%; original river intestine
