Embodiment

[0034] Step 1, put the microbial metering container 6 into the groove 4;

[0035] Step 2: Push out the superabsorbent resin 18 of the sampling rod 16 using the push-pull device 22 to collect a water sample from the water containing microorganisms, and then use the push-pull device 22 to pull the superabsorbent resin 18 containing the water sample back to protect the water sample Cover 23 miles to prevent the collected water samples from being affected by the external environment;

[0036] Step 3: Put the sampling rod 16 wrapped with one end of the superabsorbent resin 18 into the microbial measuring container 6, insert the sampling rod 16 into the microbial measuring container 6, and protect the water sample cover (23) through the first layer of aluminum foil film 9 in sequence , the measurement solution 10, the second layer of aluminum foil film 9, the measurement solution 10 uses pure water, when the second layer of aluminum foil film 9 is pierced, the pure water flows from ...

Abstract

The invention discloses a microorganism measurement device in water and a measurement method thereof, which includes a power supply port, an operation panel, a groove, a loading part, a microorganism measurement volume, a lower part of a container, an upper part of a container, a film, a measuring solution, a stirrer, a measuring electrode, a negative Electrode, positive electrode, microorganism collection terminal, sampling rod, anti-interference cap, super absorbent resin, magnet, rotor, motor. One end of the power supply port is connected to the negative electrode and the positive electrode. When the other end is connected to the power supply, the microorganisms in the liquid are measured. Negative polarization and positive polarization occur respectively on the negative electrode and the positive electrode. The microbial collection voltage and microbial measurement voltage are simultaneously adjusted through the operation panel. The microbial measurement device polarizes the microorganisms by applying an external voltage, causing the microorganisms to fall to the microbial collection through the zigzag electrode. When measured in the terminal, the number of microorganisms is directly displayed through the digital display panel. It is simple to operate, not susceptible to external interference, and has high accuracy.

Description

technical field [0001] The invention relates to the field of microbial measurement, more specifically, to a microbial measurement device in water and a measurement method thereof. Background technique [0002] Water is the source of life and a natural environment where microorganisms widely exist. All kinds of natural water contain a certain number of microorganisms. The measurement of microorganisms in water is of great significance in ensuring the safety of water sources and controlling infectious diseases, and it is also an important indicator for evaluating water quality. [0003] For the measurement of microorganisms in water, there is a plate counting method, that is, after the sample to be tested is properly diluted, the microorganisms in it are fully dispersed into single cells, and a certain amount of diluted sample solution is applied to a plate, and after cultivation, each single cell grows Propagate to form colonies visible to the naked eye, that is, a single co...
