Abstract

The invention relates to a water quality microbiological detection device used for microbiological detection in a water sample. The water quality microbiological detection device comprises a detectorbody, a detection unit and a heating unit, wherein a detection cavity is arranged in the detector body; the detector body is provided with a first communicating hole and a second communicating hole; the first communicating hole is located at the top of the detector body, so as to fill liquid in the detection cavity by virtue of the second communicating hole, and gas in the detection cavity can beemptied by virtue of the first communicating hole and can overflow from the first communicating hole; and a filter element is arranged in the detection cavity, and the filter element is connected withthe second communicating hole, so as to stop microorganisms from being discharged from the second communicating hole. The first communicating hole is formed in the top of the detector body, and the air can be evacuated, so that the detection cavity can be full of the filled liquid, the liquid flows out, produces negative pressure and sucks in the water sample, the two communicating holes in the detector body can be conveniently and directly connected with a pipeline, and online real-time automatic detection on the microorganisms is realized.

Description

technical field [0001] The invention belongs to the field of water quality detection, in particular to a water quality microorganism detection device and detection method. Background technique [0002] In recent years, the microbial pollution of surface water, groundwater, river water, drinking water and other water bodies in my country has become increasingly serious. Among them, microbial pollution of drinking water quality has the most direct impact on human beings, causing large-scale disease outbreaks and seriously endangering human health. my country's "GB5749-2006 Sanitary Standards for Drinking Water" stipulates that the total coliforms, heat-resistant coliforms, and Escherichia coli in the microbial indicators must not be detected per MPN / 100mL, and the total number of colonies per CFU / mL should not exceed 100. [0003] At present, microbial detection in my country is mostly used in laboratory testing. Traditional national standard methods such as multi-tube ferment...
