Problems solved by technology

In addition, the use of this type of filter cannot obtain water samples of different steps, and when the volume of filtered water samples is large, it is necessary to maintain a high vacuum negative pressure to ensure that the water samples pass through the filter membranes smoothly, thus limiting its application in hydrosphere research.

Embodiment Construction

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0032] like figure 1 As shown, a portable water sample cascade suction filtration system includes a filter 17, a conduit 1, a suction filter bottle 2, a portable case 3, a first suction latex tube 4, a second suction latex tube 5 and a third suction pressure Latex tube 8; said filter 17 has two, all is provided with corresponding water system microporous filter membrane in each described filter 17; It communicates with the upper and lower ports of the conduit 1, and the top of the upper filter 17 is connected to the surface of the water body or a position at a depth of 1m through the sampling latex tube 11, and the bottom of the lower filter 17 is connected to the removable seal. The top opening of the suction filt...

Abstract

The invention relates to a portable step-by-step water sample suction filtration system. The system comprises two filters, a guide pipe, a suction filtration bottle, a portable box, a first suck-press latex tube, a second suck-press latex tube and a third suck-press latex tube, wherein a corresponding water system micropore filtration membrane is arranged in each filter; the two filters are detachably communicated with upper and lower ports of the guide pipe in a sealed manner respectively; a vacuum pump and a storage battery for supplying electric energy to the vacuum pump through a power switch are placed in the portable box; one end of the first suck-press latex tube and one end of the second suck-press latex tube are detachably communicated with the guide pipe and the suction filtration bottle in a sealed manner, the other ends of the first suck-press latex tube and the second suck-press latex tube are joined and connected to the end part of the third suck-press latex tube communicated with the vacuum pump. By means of the suction filtration system, particle suspended matters/microorganisms with different particle sizes or pore sizes in a water sample can be separated on the field site, following research is met, and besides, the system can be used for collecting water samples filtered step by step.

Description

technical field [0001] The invention relates to the field of scientific research related to the hydrosphere, in particular to a portable cascade suction filtration system for water samples. Background technique [0002] Water is the basic substance for the survival, reproduction and evolution of life on earth, and an important medium for the migration and transformation of matter and energy flow in the earth system, and constitutes a continuous and irregular circle, namely the hydrosphere. Not only are there a huge number of micro organisms with diverse genetic and metabolic methods living in the hydrosphere environment, but these micro organisms also cause a large amount of soluble substances and suspended particles to exist in the hydrosphere by driving the earth's element cycle. Therefore, the study of micro organisms, soluble substances and suspended particles in the hydrosphere can provide a scientific basis for protecting the ecological service functions of the hydrosp...
