Abstract

The invention relates to an on-site rapid blue-green algae tester comprising a buoyancy device and a main frame, the buoyancy device is fixedly connected to the main frame. A depth adjusting device isarranged on the main frame; a horizontal absorbance measuring device, a vertical absorbance measuring device, a temperature sensor, a luminosity sensor and a depth sensor are arranged on the depth adjusting device; the midpoint of the optical path of the vertical absorbance measuring device and the center of the horizontal absorbance measuring device are located on the same horizontal plane; andthe depth adjusting device, the horizontal absorbance measuring device, the vertical absorbance measuring device, the temperature sensor, the luminosity sensor and the depth sensor are all in signal connection with a signal receiving and control device. According to the invention, blue-green algae form observation and blue-green algae data measurement in an actual water body become possible, blue-green algae of different depths can be observed, and because the blue-green algae is measured under the completely open natural condition, the obtained blue-green algae concentration and distributioncan better reflect the real situation, related research can be accurately guided, and a correct treatment scheme can be made.

Description

technical field [0001] The invention relates to the field of environmental monitoring experimental equipment, in particular to an on-site cyanobacteria rapid tester. Background technique [0002] Existing liquid particle counters are mostly used in the laboratory, and even those portable instruments require sampling or drawing water samples in the field. For all tests requiring sampling, the representativeness of the sample taken is always unknown. Tiny particles may settle in the sample container, may collide with each other and combine, may be adsorbed on the wall of the sample container, may also be broken due to shaking, and other changes may occur during this period, especially for aquatic microorganisms such as cyanobacteria. In addition, sampling analysis is often difficult to obtain real results. The most typical one is like cyanobacteria, whose distribution changes in different regions, different depths, different times, and different turbidity in the water body. ...
