A portable rapid bacteria collection system for rapid detection of microorganisms in bottled drinking water

Abstract

The invention discloses a portable rapid bacterium-collecting system used for rapid detection of microbes in filling drinking-water. The portable rapid bacterium-collecting system comprises an operation box, a box door, five bacterium-collecting devices, an ultraviolet lamp and a power box. The bacterium-collecting system provided by the invention is portable, can directly carry out sampling and bacterium collection on site in a to-be-detected water plant, and is not restricted by environmental conditions for usage of the system and capable of effectively shortening a detection period. The system provided by the invention is of an enclosed structure, so contamination can be effectively prevented, and the accuracy of bacterium collection can be effectively guaranteed. The system can pump water samples into a first bacterium collection device and a second bacterium collection device according to culture needs of different bacteria, so the disadvantage that traditional detection needs sampling a plurality of times is overcome, and subsequent classified culture of different bacteria is facilitated. The system can realize pumping and filling of water samples and has the advantages of convenient operation, high bacterium collection efficiency and great reduction in labor intensity. Frequently used detection devices can be mounted on the outer side of the system, so the application scope of the system is wide.

Description

technical field [0001] The invention belongs to the technical field of food microorganism detection, and in particular relates to a portable rapid bacteria collection system for quick detection of microorganisms in bottled drinking water. Background technique [0002] At present, bottled water is increasingly becoming the main source of drinking water for ordinary people. The market demand continues to increase, and the number of manufacturers continues to increase. However, the quality of the bottled water is accompanied by problems, especially the water bottles and buckets used for the bottled water. Health and safety issues have become the focus of social attention. Food-borne biological contamination is one of the important factors of bottled water pollution, mainly including the total number of colonies, coliforms, mold yeast, Pseudomonas aeruginosa and other pathogenic bacteria. According to literature and reports, there are a large number of unqualified bottled water...

AI Technical Summary

Problems solved by technology

Although some new rapid detection methods for microorganisms have appeared at present, they are mainly limited by the environmental conditions of use and can only be completed in the laboratory.

Usually, when the filling water arrives at the laboratory to collect bacteria, for mold yeast and Pseudomonas aeruginosa, the membrane filtration method specified in the standard is used to collect bacteria, while for coliform bacteria, it is directly pumped and cultivated. As far as the sampling equipment is concerned, there is the disadvantage of repeated sampling, and the sampling efficiency is very low, especially for the common 18.9L bottled water, usually the object of sampling is 5 barrels of water in each group, at this time, the water needs to be collected manually It is not only inconvenient to operate, but also labor-intensive to filter the bacteria by pouring them into different filter membranes. The current sampling and testing instruments are all open, and there is also the problem of being easily contaminated, which in turn leads to false positive test results.

In addition, the traditional sampling equipment needs to use a flame to burn the filter piece after each filter cup is filtered, which is time-consuming and not easy to ensure the accuracy of the experiment. Open flames are a great safety hazard
