Description

technical field [0001] The invention relates to water quality detection equipment, in particular to an automatic water quality detection equipment. Background technique [0002] During the operation of water treatment projects and facilities, it is necessary to conduct regular analysis and testing of physical and chemical analysis items in water. For analysis items such as total hardness, calcium hardness, total alkalinity, and chloride ions, they are usually analyzed by standard solution titration in the laboratory. The method is to determine the consumed volume of the standard solution by judging the color change at the end of the reaction, thereby calculating the water quality analysis data. [0003] Since routine water quality analysis is carried out manually in the laboratory, the following problems may occur during the actual testing process: [0004] (1) Manual testing generally needs to take samples from the field and send them to the laboratory for analysis, which ...

AI Technical Summary

Problems solved by technology

[0004] (1) Manual testing generally needs to take samples from the field and send them to the laboratory for analysis, which takes a certain amount of time, so there is a certain lag in the water quality analysis data

[0005] (2) The same water quality analysis project will have sampling errors, titration errors and end point judgment errors due to different operating methods among different laboratory personnel, which will affect the accuracy of the data, thereby reducing the water quality analysis data at different time points Comparability

[0006] (3) For industrial wastewater membrane advanced treatment systems with large water quality fluctuations, the total hardness, calcium hardness, and total alkalinity often fluctuate greatly, and it is necessary to adjust the dosing amount in time to prevent membrane fouling, so higher Analysis frequency, manual analysis cannot adapt to high-frequency continuous analysis

[0007] (4) During the operation of the industrial circulating cooling water treatment system, analysis items such as total hardness, calcium hardness, total alkalinity, and chloride ions are key control indicators, which can reflect the trend of scaling and corrosion. When the water quality fluctuates greatly, The frequency of manual testing data is low and the speed is slow, so it is impossible to take corresponding measures in time
