Description of the invention (1) The present invention relates to a method and device for water quality monitoring, and more particularly to a multifunctional method and device for water quality monitoring. In the proportion of water used for general industrial hemp production, the amount of water used for cooling accounts for a large part. Therefore, no matter how to save the cost of self-use water or from an environmental protection standpoint, how to control the water quality of cooling water to increase the concentration rate and reduce Discharge of water is an important issue. The function of controlling the water quality can also prevent the pipeline from scaling up and blocking, and even cause corrosion and rupture, which can further avoid accidents caused by pipeline rupture. At present, the first step of general water quality monitoring, whether it is entrusted to a professional water treatment company or not, is to obtain a water sample on site and take it back to the laboratory. The inspection work performed in the laboratory generally requires the detection of pH 値, calcium ion concentration, and M alkalinity; the second step is to consult the data chart of Baiguan according to the test; then the saturation index can be calculated in the third step Alas, the calculation process is very troublesome. Due to the application of traditional testing methods and procedures, and the waste of time to return to the site for sampling, there will be a few hours from sampling to knowing the test results; if it is entrusted to a professional water treatment company to perform, the results will usually be obtained on the second day of sampling. The delay in time in all of the above processes will inevitably hinder the immediate monitoring and immediate remediation of water quality monitoring. Although some people also consider installing the experimental device at the place where the water sample is taken for real-time analysis, it is an ideal that is not practical and extremely inconvenient. At present, the methods for analyzing calcium (Ca.) hardness include atomic absorption spectrometry (AA), plasma spectroscopy (ICP), ion chromatography (1C), etc., but the method that can be applied on line (on line) is # 5 ion / electrode to measure # 5 hardness device, but its price is -2- (Please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) 5

Description of the invention (2) Expensive, and because the water being tested has poorer water quality than pure water, the electrodes tested are easily damaged, so they need to be cleaned frequently, Maintenance and even calibration tests are very inconvenient. In addition, the current M alkalinity analysis methods include Methyl 〇range Colorimetd Methods, charge balance methods, and automatic titration methods. Among them, the automatic titrator measurement instrument is very expensive. The market price is about NT $ 5 〇 'The use of drugs often need to be replenished for testing' is therefore expensive, and the problem of frequent replenishment of drugs, which makes many people unwilling to adopt. A further problem with traditional water quality testing methods is that general water quality testing projects can only achieve management than conductivity and acid-base tritium. A few have better detection capabilities, and one more item is added. By redox potential (〇Rp: 〇xidati〇n Reduction Potential) Controls the content of free chlorine in the water to maintain the bactericidal effect. As for the Saturation Index (SI: Saturation Index), an important reference index that can reflect the tendency of woody fouling) and performance, there is currently no single instrument that can measure it immediately. The complexity caused by the need to look up the table makes it very difficult to read the saturation index (SI) immediately, which is why there is no such product on the market. The purpose of this case is to provide a water quality monitoring method that uses ϋΑϋ to understand water quality changes. Another object of this case is to provide a water quality monitoring method and device that can determine the relationship between calcium ions, M alkalinity, specific conductivity, acid-base (PH) degree, temperature, etc., and further use functions The relationship replaces the hardware equipment of the test instrument. The further purpose of this case is to provide a water quality monitoring method and equipment. -3- The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) ------------- (please first Read the notes on the reverse side and fill in this page), τ Γ § A7 B7 V.

Invention description (9) 値, can be converted by the multiplexer from the converter to a signal that can be matched with the central processing unit, and input to the central processing unit through the interface Microprocessor. The central processing unit also includes a read-only memory, a random memory, and an address decoder, which are not the subject of this case, so they will not be described in detail. However, the aforementioned constants, setting positions and relational expressions can be input into the central processing unit in advance through the operation keyboard or other data input device in the data operation unit, and the results can be automatically analyzed and calculated when the water quality is detected, and the results can be displayed on the control unit's display. Display, or the alarm will be issued by the controller at the same time when the normal time set by the control is exceeded, or the appropriate equipment is driven by pH meter, ORP meter, thermometer, etc., such as quantitative meter, etc., and real-time addition of chemicals to improve water quality. For example, as shown in Figure 1, when the saturation index 値 (SI) > 2, a higher concentration or a special antiscalant agent is controlled to be added; when the 値 < 〇, a higher concentration or a special anticorrosive agent is added Chemicals; When the concrete is normal between 1.0 ± 1, normal anti-corrosion and anti-fouling agents can be added regularly, and a thin layer of fouling can be formed on the inner wall of the pipeline. By using the method of the present invention, a pH meter, ORP meter, conductivity meter, etc., and a special saturation index display meter can be combined into a single model, which is convenient to operate, inexpensive, and has additional functions. The invention also calculates water quality control indexes such as calcium hardness, M alkalinity, saturation index and the like by using a functional relationship such as pH 値, specific conductivity, and temperature 値, which can improve the quality of water quality monitoring and achieve the effect of real-time control. It will be of great help. The foregoing description and drawings are only preferred embodiments in Chen Ming's case. Those skilled in the art can make some modifications from this embodiment, but should still belong to the spirit of the invention in this case. The scope of rights in this case is defined by the scope of patent application attached below. -10- (Please read the precautions on the reverse side before filling out this page) The size of this paper applies to China National Standard (CNS) A4 (2IOX297 mm)
