Background technique
In recent years, the deepening continuously in each field with microbe research, survival condition, group for aquatic microorganisms
The probing into have become in detection and evaluation aquatic ecosystem health status and Related Research Domain of structure and succession of herbaceous most has
Imitate most direct means.Compared to detection methods such as physical chemistry, microorganism detection can more it is sensitive it is more accurate expression not
Same impact factor, the influence of the substances such as different pollutants.Thus, the detection method of microorganism has become ecological evaluation and correlation is ground
Study carefully the important research analysis means in field.
However, in universal microorganisms in water sampling process, technical staff first by a certain amount of water sampling, after
The microorganism in water body is transferred to by Vacuum filtration device and is filtered on machine filter film, followed by the various of related microorganisms
Analysis detection.Since water sampling is different from the environment that microorganism acquisition needs, often field sampling is needed to transfer to laboratory
The sampling work of microorganism is not carried out.Simultaneously as microbiological analysis often needs to carry out the difference analysis between parallel sample.Cause
This, the collection process of entire microorganisms in water seems especially complicated, also increases the workload of technical staff, greatly reduces
The efficiency of sample acquisition, and since there are certain sample interval, microorganism may be because being in the anaerobic and aerobic stage
And lead to the change of itself structure of community, and then a degree of damage and data distortion are caused to microorganism itself.
Simultaneously as the demand of different research and analysis means, the in-situ acquisition of microorganisms in water may be needed in water body
Carried out under the conditions of certain depth, thus, the depth acquisition of partial region (such as reservoir, dam etc.) can increase with the depth of sampling and
