Abstract

The invention relates to bacterium detecting equipment and particularly discloses an online analyzer of Escherichia coli, and the online analyzer comprises a constant temperature box and a sampling pump, wherein a temperature sensor, a heating device, an analyzer mainboard, a culture dish and a fluorescence spectrophotometer are arranged in the constant temperature box; a display is arranged outside the constant temperature box; the analyzer mainboard is electrically connected with the temperature sensor, the heating device, the fluorescence spectrophotometer and the display; and the outlet of the sampling pump is in pipe joint with the culture dish, and the inlet of the sampling pump is connected with an external sample pipe. The online analyzer disclosed by the invention can be used for realizing the automation and integration of the functions such as the sampling, culturing, analyzing, displaying and the like of the Escherichia coli detection, has the advantages of high detection sensitivity, high detection speed, low cost, no secondary pollution, small maintenance amount and low operation cost and can be used for realizing the automatic online analysis and monitoring of the Escherichia coli.

Description

technical field [0001] The invention relates to bacteria detection equipment, in particular to an Escherichia coli on-line analyzer for automatic sampling and detection. Background technique [0002] Escherichia coli is the most abundant bacterium in human and animal feces, and it is an internationally recognized general indicator for testing the epidemiological safety of various water quality and food. The more Escherichia coli, it indicates that the water source is more polluted by human and animal feces, and the possibility of pathogenic bacteria is relatively higher, which brings potential dangers to human health, especially enterohaemorrhagic Escherichia coli can cause human hemorrhagic enteritis Even death, in recent years has been popular and broke out in the United States, Japan, Britain, Germany and other countries. In recent years, in the implementation of HACCP management in some countries, the detection of Escherichia coli has been used as a monitoring index of ...
