Microbial detection and analysis of the barreled pure water in the campus

摘要

To detect the. sanitary status of pure water at different times in the campus, including to detect the total bacterial count, the coliforms, mould and yeast, this document explained and demonstrated the sanitary status of the barreled pure water through water dispensers. By the experiment, the results showed that the drinking fountain caused the pure water pollution, so the unheated pure water flowing though the drinking fountain were not qualified. And the longer the pure water samples were cultured, the more the aerobic bacterial count of water samples significantly exceeded the standard. After these samples were cultured for five days, all samples had be uncountale.
