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 biological pollution detector is characterized by: at least a housing, a water inlet tank on one side of the housing, the water inlet tank is connected with a peristaltic pump to pump a quantitative water sample to a reaction tank with a magnetic stirrer, and a solution One end of the oxygen probe extends into the reaction tank of the water sample to be tested to form a sealed system, and the other end is connected to the processing circuit to transmit the test data. After the test is completed, the backwash pump will perform the equipment backwash step. The processing circuit includes a SIM card Modules, relay modules and power modules are used to send positioning signals and detection data to the control room.

[0019] There are backwash water inlets and battery replacement ports on the shell.

[0020] One end of the dissolved oxygen probe is wrapped with a leather adapter plug, which can immediately form a sealed system ...

Abstract

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 and detection device, in particular to a portable water quality biological pollution detector. Background technique [0002] The World Health Organization (WHO) pointed out in the "Drinking Water Quality Guidelines" that most of the sanitation problems of drinking water are related to the contamination of microorganisms (bacteria, viruses, protozoa or other biological sources). In recent years, due to frequent pollution accidents and normal pollution of source water, the safety of drinking water in our country is facing severe challenges. Under this situation, the risk warning of biological pollution of drinking water is particularly important. [0003] A necessary condition for biological pollution accidents is that there should be a certain level of Assimilable Organic Carbon (AOC) in the water to support the growth of microorganisms. Therefore, the level of AOC in the water can be measured to indirectly reflect the bio...
