Problems solved by technology

[0004] At present, chemical analysis of water samples can accurately detect the content of target pollutants. However, due to the wide variety of pollutants, this technology for chemical analysis of water samples cannot quickly determine the main toxic substances, and thus cannot accurately kill microorganisms in the wat

Embodiment Construction

[0014] The invention will now be described with reference to the accompanying drawings.

[0015] The inventor's principle is: some aquatic organisms are highly sensitive to changes in water quality, and by analyzing the behavior of a certain number of aquatic organisms, it is possible to quickly and accurately determine whether the water quality is poisoned or polluted. Therefore, the inventor believes that the water pollution early warning technology based on the analysis of biological toxicity can detect, warn and deal with water pollution incidents in a timely and accurate manner, effectively ensure water quality, thereby avoiding the occurrence of drinking water pollution accidents, and at the same time, it can also improve the water treatment process. The system control provides accurate water quality data.

[0016] For example, fish are very sensitive to changes in the chemical composition of the water. At the same time, fish are also vertebrates closest to humans. There...

Abstract

The invention discloses a water quality pollution early warning method, which comprises the following steps: introducing raw water to be monitored into a fish tank, and putting a certain number of small fish into the fish tank; acquiring continuous frames of image sequences in real time, and converting the frames into digital images; smoothly processing the acquired frames of the image sequences; performing threshold segmentation treatment on the frames of the image sequences after smooth processing; performing noise removal treatment on the frames of the image sequences after the threshold segmentation; calculating a kinematical parameter of the small fish according to the frames of the image sequences after the noise removal treatment; setting a preset kinematical parameter, and comparing the calculated kinematical parameter with the preset kinematical parameter; and judging whether the calculated kinematical parameter is greater than the preset kinematical parameter or not, and determining that the water quality to be monitored is polluted when the calculated kinematical parameter is greater than the preset kinematical parameter. The method has the advantages that the method is timely and accurate to detect water quality.

Description

technical field [0001] The invention relates to a water quality pollution early warning technology, in particular to a water quality pollution early warning technology using fish as early warning organisms. Background technique [0002] At present, the water quality problems faced by my country's water supply industry mainly include two aspects. One is that people's requirements for water quality standards continue to increase; the other is that drinking water sources in today's society are generally polluted by industry. How to effectively improve water quality and ensure the sustainable development of urban water supply has become an urgent problem to be solved in modern cities. There are few technical applications for water quality forecasting in China. Therefore, when the water quality is polluted, we can only discover and deal with the water quality pollution when there is odorous water flowing out of the tap water pipes or residents report. [0003] This kind of infor...
