Pathogenic microorganisms existing in water environment cause great harm to human health, not only can cause cholera, viral hepatitis, poliomyelitis, typhoid, paratyphoid, infectious diarrhea and other water source infectious diseases to be conquered and epidemic, but also extremely bad harm and social adverse effect are caused. Therefore, in order to effectively control outbreaks of water-borne diseases, it is necessary to detect pathogenic microorganisms in various water bodies. However, the pathogenic microorganism content in the water environment is very small and is far lower than the detection sensitivity of the existing monitoring method. Therefore, if it is desired to effectively detect pathogenic microorganisms in water, a large amount of water must first be concentrated to recover a small amount of pathogenic microorganisms from different water bodies for detection. At present, the enrichment method of pathogenic microorganisms in water is mainly an adsorption elution method, wherein a water sample is passed through a filter column containing solid particles, and after the pathogenic microorganisms are adsorbed to the surfaces of the particles, the pathogenic microorganisms are recovered through specific elution liquid.
The existing intelligent water environment disease source microorganism enrichment equipment (patent CN 201220368867) continuously flows a water body through a pathogenic microorganism enrichment filtering column through a peristaltic pump, and the pathogenic microorganisms in the water are recovered through a positive charge-carrying filter material in the water body, so that the virus recovery rate is high, the treatment water quantity is large, the operation is simple and convenient, the intelligent water environment disease source microorganism enrichment equipment is suitable for enriching various water body pathogenic microorganisms such as large-volume drinking water, surface water and reuse water, direct contact between operators and a biological pollution water sample (particularly a water body containing high-concentration pathogenic bacteria) is reduced as much as possible, and the operators are effectively protected. However, when the turbidity of the water body is high, the turbid matters are easy to gather at the upper half part of the filtering column after the water body passes through the pathogenic microorganism enrichment filtering device, and the water body is blocked from passing through the filtering column and the air pressure in the column is increased, so that the pipeline is further caused to spray, and the smooth implementation of virus enrichment is prevented.
