Abstract

The invention relates to an on-site cyanobacteria rapid tester, which comprises a buoyancy device and a main frame, the buoyancy device is fixedly connected to the main frame, the main frame is provided with a depth adjustment device, and the depth adjustment device is provided with a horizontal absorbance measuring device, a vertical absorbance Measuring device, temperature sensor, photometric sensor and depth sensor, the midpoint of the optical path of the vertical absorbance measuring device is at the same level as the center of the horizontal absorbing rate measuring device, the depth adjustment device, the horizontal absorbing rate measuring device, and the vertical absorbing rate measuring device , the temperature sensor, the photometric sensor and the depth sensor are all signal-connected to the signal receiving and control device. This measurement device makes it possible to observe the shape of cyanobacteria and measure the data of cyanobacteria in the actual water body, and can observe cyanobacteria at different depths. Since it is measured under completely open and natural conditions, the concentration and distribution of cyanobacteria obtained can better reflect the real situation. It can accurately guide relevant research and formulate correct governance programs.

Description

technical field [0001] The invention relates to the field of environmental monitoring experimental equipment, in particular to an on-site cyanobacteria rapid measuring instrument. Background technique [0002] Existing liquid particle counters are mostly used in laboratories, and even those portable instruments require sampling or water samples in the field. For all tests that require sampling, the representativeness of the sample taken is always unknown. Microscopic particles may settle in the sample container, may collide and combine, may be adsorbed to the walls of the sample container, or may be broken by shaking, among other changes, especially in aquatic microorganisms such as cyanobacteria. In addition, sampling analysis is often difficult to obtain real results. The most typical example is cyanobacteria, whose distribution varies in different areas and depths, different times, and different turbidity in the water body. Therefore, an instrument that can directly me...
