Diatom biological water quality monitoring system

Abstract

A diatom biological water quality monitoring system includes a biological cultivation and collection device 4, an aquatic organism experiment processing device 5, an aquatic organism identification device 7, and a biological classification and water quality determination system 9. A control sample point is arranged at a monitoring area generally, a diatom sample of the designed area is collected through the collection device, the diatom sample is pretreated in a laboratory to remove diatom organic matters and is treated to remove organic salts, a siliceous shell is obtained and then cleaned and dried to pre-prepare a diatom slide, preliminary testing is carried out, and after the slide is tested to be qualified, the slide is sealed by an adhesive with the refractive index of about 1.7. The slide 21 is subjected to diatom individual identification and counting by the identification device 7, diatom individuals are displayed in an image mode in the system 9, and the diatom sample can be photographed for preservation. The system 9 divides the identified diatom species into different class groups and identifies different types of indicator species, at the same time, the system 9 calculates various diatom indexes on the basis of various mathematical models, and thus diatom biological resource survey and biological water quality monitoring functions are achieved.

Description

technical field [0001] The invention relates to a water quality biological monitoring system in rivers and lakes, belonging to the field of water environment monitoring. Background technique [0002] The problem of water resource pollution in my country is very serious, and major water pollution incidents occur frequently. An important factor exposed by major accidents is the lack of monitoring of the water environment, which makes polluters have a fluke mentality, and the discovery of many emergencies is due to the emergence of a large number of Dead fish or dead poultry, another problem is that there are still large-scale streams in our country that have not been evaluated, and there is an urgent need to monitor and evaluate them. These realities necessitate the development of economical and effective biomonitoring techniques because domestically, biological data relevant to national water resource decision-making is extremely scarce. [0003] Benthic animals, aquatic vasc...

Problems solved by technology

[0004] There has been a history of research on the taxonomy and ecology of diatoms, but the research on water quality monitoring has just started. There are many problems about how to arrange sampling points reasonably, the technical requirements for diatom experiments, and the configuration of identification instruments.
