In-situ multi-channel water body enriching, filtering and fixing device and method

Abstract

The invention belongs to the field of deep sea in-situ water body enriching, filtering and fixing, and particularly relates to an in-situ multi-channel water body enriching, filtering and fixing device and method, the device comprises an enriching and filtering part, a multi-channel conversion part, a pump injection part and a control and power supply part, and enriching, filtering and fixing are completed through mutual circulation of liquid channels of all the parts. According to the invention, enrichment and filtration requirements of water microorganisms are met, and high-flux filtration of water and injection of various base solutions are completed by using a multi-pump-head mode of a peristaltic pump and a multi-channel rotating valve body; the sampling channel is multiple, the fixing effect is good, work is flexible and stable, a filtering membrane sample can be rapidly and effectively obtained, in-situ fixing is carried out, the connectivity and the sealing performance are completed through a one-way valve body, a large number of external structures and extra valve bodies are reduced, and great practicability is achieved.

Description

technical field [0001] The invention belongs to the field of deep sea in-situ water body enrichment filtration and fixation, in particular to an in-situ multi-channel water body enrichment filtration and fixation device and method. Background technique [0002] High-throughput, rapid and accurate enrichment and filtration of filtered water samples is the primary condition for the study of marine water microorganisms. Therefore, major domestic marine research institutions have carried out research and development of related equipment. The existing underwater equipment is divided into direct water body equipment, in-situ enrichment and filtration sampling equipment, in-situ enrichment fixed equipment, etc. There are various types, including fidelity and pressure-holding samplers, deep-sea microbial culture chambers, Deep-sea microbial in-situ enrichment device, eight-channel deep-sea in-situ microbial culture device, grid-type microbial culture device, large-volume water sampl...

AI Technical Summary

Problems solved by technology

[0003] To sum up, there are many enrichment filtration systems involved, but very few involve multi-channel enrichment filtration and fixed systems in deep water areas, which involve the injection of multi-channel valves and fixatives, which are relatively common methods of use It is a multi-channel solenoid valve that completes the multi-channel fluid on-off, and the injection of the stationary liquid is completed by an additional electric pump, but it has not been found that the same pump and rotary valve are used to complete this work.
