Problems solved by technology

When there are many impurities in the water sample, the impurities need to be filtered before the collection and enrichment of microorganisms, otherwise the filter used for the collection and enrichment of microorganisms will be blocked too quickly, and it is not convenient for the separation of microorganisms in the enrichment
However, if the filtering effect of the pre-filter device is too strong, a large number of microorganisms will be blocked by the pre-filter device and cannot be enriched on the filter disc.

Abstract

The invention discloses a collecting and filtering device for microorganisms in a water sample. The collecting and filtering device comprises a primary filtering cylinder, a fine filtering cylinder and a collecting and filtering cylinder which are sequentially connected in series. The primary filtering cylinder is connected with a water inlet pipe, the bottom of the primary filtering cylinder is connected to the top of the fine filtering cylinder through a connecting pipe, and a switch valve is mounted on the connecting pipe; a rotating shaft is mounted in the primary filtering cylinder, a plurality of metal wire meshes are mounted on the rotating shaft, the rotating shaft is connected with a motor, and a PP cotton filter element is mounted in the fine filtering cylinder; a water storage tank and a filter tank are arranged in the collecting and filtering cylinder, the water storage tank is connected with the fine filtering cylinder, a submersible pump is mounted in the water storage tank, a mounting rack is fixed in the filter tank, a plurality of mutually parallel slots are connected to the mounting rack, filter discs are inserted into the slots, nozzles in one-to-one correspondence with the slots are connected to the mounting rack, and a back-flow hole communicated with the water storage tank is formed in the bottom of the filter tank. The defects in the prior art can be overcome, and the service life of the filter disc is prolonged while the microorganism collection and enrichment efficiency is guaranteed.

Description

Technical field[0001]The present invention relates to a water sample detection, in particular a collection filtering apparatus for microorganisms in a water sample.Background technique[0002]Microbiological detection is an important test item during water sample detection. When the impurities in the water samples, impurities need to be filtered before the collection of microorganisms is required, otherwise it will result in a filter for microorganisms to collect enriched filters, which is not convenient for the separation of microorganisms in the rich. However, if the filtration effect of the front filter device will cause a large number of microorganisms to be blocked by the front filter device, it cannot be enriched on the filter.Inventive content[0003]The technical problem to be solved by the present invention is to provide a collection filter device for microorganisms in water samples, which can solve the prior art shortcomings, and extend the useful life of the filter while ensu...
