Embodiment Construction

[0021] The present invention will be described in further detail below.

[0022] like Figure 1 to Figure 4 As shown, a method for measuring on-site cyanobacteria using a rapid measuring instrument comprises the following steps, step 1, according to the specific water body turbidity, adjust the optical path of the vertical absorbance measuring device 14 and the horizontal absorbance measuring device 10 to ensure that the vertical absorbance measuring device The optical path center of 14 and the optical path center of the horizontal absorbance measuring device 10 are on the same horizontal plane, and the optical path is equal; Step 2, correct the horizontal absorbance measuring device 10 and the vertical absorbance measuring device 14; The photometric sensor 12 and the multi-head digital converter are calibrated; step 4, put the fast measuring instrument into the water smoothly, observe the readings, and start to read and record the measurement time, the light on the water surf...

Abstract

The invention relates to an on-site cyanobacteria measurement method using a rapid measuring instrument, which comprises the following steps: step 1, determine the optical path of a vertical light absorbance measuring device and a horizontal light absorbing rate measuring device according to specific water body conditions, and set up hardware; step 2, adjust the measuring device Calibration with sensors, etc.; step 3, start the measurement, read and record the measurement time, light on the water surface, air temperature and water temperature, record the measurement depth, underwater light, temperature, horizontal absorbance and vertical absorbance, to obtain the most realistic Cyanobacteria distribution data.

Description

technical field [0001] The invention relates to the field of environmental protection testing, in particular to an on-site cyanobacteria determination method using a rapid analyzer. Background technique [0002] Existing cyanobacterial counts or assays are mainly performed in the laboratory. This may be because cyanobacterial assays often use common testing techniques and equipment, such as hemocytometers, or fluorophotometers. Indoor testing requires sampling, storage and transportation. Even those portable instruments require field sampling. For all tests that require sampling, the representativeness of the sample taken is always unknown. For example, tiny particles may settle in the vial, may collide with each other and bind, may be adsorbed to the vial wall, and other changes may occur, especially in living organisms such as cyanobacteria. In addition, sampling analysis brings practical difficulties to the study of the distribution of cyanobacteria in different regio...
