Abstract

The invention discloses a field natural water sample collection system and method, belongs to the technical field of water quality analysis and testing, and solves the problems that sampling cannot beinterrupted at any time, the replacement speed of a filter membrane is low and the working efficiency is low during existing field water sample collection. The field natural water sample collection system comprises a water containing funnel, a filtering device and a sample collecting bottle, wherein the water containing funnel is used for containing an original field natural water sample, the filtering device is used for filtering impurities in the original natural water sample, and the sample collecting bottle is used for storing the natural water sample filtered by the filtering device; thewater containing funnel, the filtering device and the sample collecting bottle are sequentially connected along the flowing direction of a natural water sample; and the filtering device is detachablyprovided with a filtering assembly. According to the invention, the sampling can be interrupted at any time according to needs, the filter membrane can be rapidly replaced, and the collection efficiency of field natural water samples is greatly improved.

Description

technical field [0001] The invention relates to the technical field of water quality analysis and testing, in particular to a system and method for collecting natural water samples in the field. Background technique [0002] Collecting natural water samples (such as rivers, lakes, oceans, etc.) in the field and analyzing various physical and chemical indicators of natural water samples is an important part of physical, chemical, biological, and environmental science research on natural water samples. [0003] At present, when geologists collect natural water samples in the field, since there are sediment, gravel and other debris in the water samples, they need to filter out impurities at the collection site. The existing water sample collection device comprises a water-filled funnel, a filter membrane and a sample collection bottle. During sampling, the filter membrane is covered on the mouth of the sample bottle, and then the liquid outlet of the funnel is connected to the ...
