Multi-parameter water quality analysis method and system

Abstract

The invention discloses a multi-parameter water quality analysis method. The method comprises the following steps: (1) water sample acquisition, namely controlling a peristaltic pump to guide a measured water sample to flow to a measurement region or a laboratory, so as to obtain the measured water sample flowing at a stable pressure and stable speed; (2) water sample measurement, namely guiding the measured water sample in the step (1) to a circulation tank module, and inserting a measuring electrode into the circulation tank module so as to simultaneously measuring multiple parameters of water quality; (3) data collection, namely collecting measurement signals by virtue of a multi-parameter electrode data collection instrument, and processing the measurement signals, so as to obtain data signals; and (4) data processing, namely outputting the data signals in the step (3) to a computer, processing the data signals by virtue of an electrode data processing system, and storing the data signals in a text format manner, so as to acquire accurate measurement data. The invention further discloses a multi-parameter water quality analysis system.

Description

technical field [0001] The invention relates to the technical field of water quality measurement, more specifically, it relates to a multi-parameter water quality analysis method and system. Background technique [0002] The electrochemical electrode method is to obtain the concentration in the solution by measuring the activity of the measured component in the water sample. The electrochemical electrode method is quickly applied to flow monitoring and automatic detection systems because of its low installation cost, simple operation, flexible configuration, and no contamination of the measured water sample or solution system. It is especially suitable for large data acquisition such as online detection and monitoring. , such as: scientific research, laboratory small test or parameter test in the pilot test stage or the ultimate product life limit, component analysis of resource exploration, production line feeding, product process changes, water quality testing of agricultu...

AI Technical Summary

Problems solved by technology

Usually the electrodes are configured with their own brand of instruments. The same electrode has different diameters designed by different manufacturers. It may not be able to connect with third-party instruments. Each measurement needs to design a different flow cell, which is labor-intensive. , the cost is high; while the industrial electrode type electrode is equipped with a reinforced protection design, the volume is larger, and it cannot measure samples in small containers, and it is difficult to install and the cost is higher;

[0004] 2. General-purpose laboratory electrodes are not suitable for on-site work in harsh environments. Industrial electrodes can be used directly in some developmental production sites or flow tanks, but are often limited by their size and high price

If the water sample to be tested is in a closed environment, such as: boilers, food fermentation tanks, etc., it will require more expensive and complicated installation costs to open up a working surface that accommodates multiple electrodes;

[0005] 3. If the flow rate of the water in the flow cell is too high, it may have a certain impact on the measurement sensitive components of the electrode, which will accelerate wear and reduce the working life;

[0006] 4. The electrode is in the flowing water body with constant speed change, and the electric field of the loop is also constantly changing, which leads to the instability of the measurement data
