家用洗衣机微生物污染状况研究

摘要

在生活中，洗衣水往往是被人们所忽略的污染源。为了人们更加健康的生活更加健康的洗衣，本文对家用洗衣机内外筒以及洗衣水中细菌总数和大肠菌群数进行了取样测定，结果表明，各种样品的细菌总数结果很相近，并且远远超出了公共用品中其它公共用品卫生的标准，即细菌总数评价指标不大于300cfu／25cm^2；洗衣机内外筒的细菌总数结果相近。最后，本文通过分析其造成的污染状况，从而引导人们养成科学的洗衣习惯。%Laundry water, a pollution source,which is often ignored. In order to secure a healthy life, this paper determined the total bacteria and coliform bacteria in laundry water as well as the inner and outer cylinders in washing machines. The results showed that the total number of bacteria for the various samples were very similar, far beyond the health standards of no more than 300cfu/25cm^2. The total number of bacteria in washing machine＇s inner and outer cylinders was very similar. By analyzing the pollution situation, this paper aims to provide guidance to scientific laundry habits.
