Problems solved by technology
The traditional method of using P17 and NOX strains to detect AOC in water has the disadvantage that it can only be sampled regularly and cannot be tested in real time. Moreover, this method has a slow detection speed and high requirements for operators. Therefore, it is difficult to ensure early warning of the risk of microbial contamination of water quality. effect

Embodiment
[0018] Such as figure 1 As shown, a portable water quality bio-contamination detector is characterized in that it includes at least a housing, and a water inlet tank is provided on one side of the housing, and the water inlet tank is connected to a peristaltic pump to pump quantitative water samples to a reaction tank with a magnetic stirrer. One end of the oxygen probe extends into the reaction tank of the tested water sample to form a sealed system, and the other end is connected to the processing circuit to transmit the detection data. After the detection is completed, the backwashing pump will carry out the backwashing step of the equipment. The processing circuit includes the SIM card module, relay module and power supply module for sending positioning signals and detection data to the control room.
[0019] There is a backwash water inlet and a battery replacement port on the shell.
[0020] One end of the dissolved oxygen probe is wrapped with a leather adapter plug, w...

The invention aims at providing a portable water-quality biological pollution detector which is capable of rapidly detecting biological pollution risk of water-source water and drinking water, early warning standard exceeding, and is simple to operate. The portable water-quality biological pollution detector is characterized by comprising that the detector at least comprises a shell, one side of the shell is provided with a water inlet tank, the water inlet tank is connected with a peristaltic pump, and a certain amount of a water sample is pumped into a reaction tank with a magnetic stirrer; one end of a dissolved-oxygen probe stretches into the reaction tank of a to-be-detected water sample, and a sealed system is formed; and the other end of the dissolved-oxygen probe is connected with a processing circuit, detection data is transmitted, and after detection is finished, a backwashing water pump performs equipment backwashing.
Description
technical field [0001] The invention belongs to a detection device, in particular to a portable water quality biological pollution detector. Background technique [0002] The World Health Organization (WHO) pointed out in the "Guidelines for Drinking Water Quality" that most of the hygiene problems of drinking water are related to the pollution of microorganisms (bacteria, viruses, protozoa or other biological sources). In recent years, due to frequent pollution accidents and normal pollution of source water, my country's drinking water safety is facing severe challenges. In this situation, early warning of the risk of drinking water biological pollution is particularly important. [0003] A necessary condition for the occurrence of biological pollution accidents is that there should be a certain level of assimilable organic carbon (Assimilable Organic Carbon, AOC) in the water to support the growth of microorganisms. Therefore, the risk of biological pollution of water qua...
