Problems solved by technology

Microscopic observation is a fast and effective method for extracting microscopic information in water bodies, but this method is time-consuming, cannot reflect the indicative microbial status in water bodies in a timely manner, and is easily affected by the subjective judgment of operators. Real-time access to quantitative information on biophase changes that limit the use of microbiological microscopy for point-of-care monitoring
At the same time, microbiological microscopes process the samples into slices and then observe them under a single light source, which destroys the three-dimensional structure of the microorganisms and cannot fully reflect all the biological characteristics of the indicated microorganisms.
[0005] Due to the above reasons, on the basis of the existing microscope observation, the inventors have solved the existing time-consuming and labor-intensive problems and the high degree of damage to the three-dimensional structure of microorganisms, and designed an efficient, fast and real-time detection three-dimensional multi-spectral online Microscopic Image Acquisition System

Embodiment approach

[0077] According to a preferred embodiment of the present invention, the scraper 2-2 is made of polyphenylene sulfide, which is a new type of high-performance thermoplastic resin with high mechanical strength, high temperature resistance, chemical resistance, It has the characteristics of flame retardant, good thermal stability, and excellent electrical properties. Its physical properties can ensure that if the sample to be tested has a certain temperature or corrosiveness, it can still be used normally, and the sample to be tested will not be corroded or rubbed by itself. Cause pollution and affect the follow-up observation results.

[0078] After the scraper 2-2 scrapes the surface of the sample tank 2-100, the surface of the sample tank 2-100 is covered with a coating film 2-3, and the coating film 2-3 can be any kind of film.

[0079] Usually, the upper covering film 2-3 is rolled into a cylindrical shape, and is erected on the stage through a pin shaft, so as to facilitat...

Abstract

The invention provides a three-dimensional multispectral online microscopic image acquisition system. The acquisition system comprises a sample feeding unit (1), a packaging unit (2), a transmission unit (3) and a microscopic collection unit (4). A to-be-detected sample is fed into a sample groove (2-100) through the sample feeding unit (1), then is packaged and fixed through the packaging unit (2) and is conveyed to the microscopic collection unit (4) through the transmission unit (3), and data collection is carried out in the microscopic collection unit (4). The invention provides the three-dimensional multispectral on-line microscopic image acquisition system which can realize the full-automatic continuous sampling and reduce the microscopic state in a water system through a three-dimensional reconstruction technology.

Description

technical field [0001] The invention relates to the technical field of water pollution prevention and control, in particular to a three-dimensional multispectral online microscopic image acquisition system and method. Background technique [0002] In the field of water treatment, the activated sludge method is an effective method for treating sewage at present. Since the birth of the activated sludge method for more than a century, the problem of sludge bulking is a worldwide problem that plagues the normal operation of sewage treatment plants. Sludge bulking will lead to problems such as the loss of activated sludge, the increase of effluent suspended matter, and the deterioration of effluent water quality, which not only reduces the processing capacity of the activated sludge system, but may even cause serious operational accidents. Moreover, once the sludge bulking phenomenon occurs, it is difficult to control and it takes a long time to repair it. Therefore, it is extre...
