Description

Automatic analysis instrument for adding concentration value of coagulant

The present application relates to an analytical instrument and, more particularly, to an automated analytical instrument for analyzing the added concentration values of a coagulant added to a water sample to precipitate contaminants in the water sample.

At present, in the wastewater treatment process of each plant, coagulation and gelation are very important procedures in wastewater treatment. This procedure is mainly to remove suspended solids which are dispersed and not easy to settle in wastewater. These non-settling suspended solids The substance has a particle size between 0.1 nm (10 ^-7 mm) and 100 μm (10 ^-1 mm). The treatment program mainly comprises adding a coagulant having a certain concentration ratio to the wastewater to be treated, adjusting to a suitable pH value, and finally adding a coagulant to generate a gelation effect, thereby dispersing the wastewater and not being easy to settle. The suspended solid matter aggregates and precipitates, thereby reducing suspended solid matter in the wastewater.

However, since the wastewater to be treated is flowing, the quality of the wastewater will change at any time, and the analysis of the concentration value of the coagulant currently added to the wastewater is realized by a manual experiment. The main processes include : After loading the same volume of the same volume of water in 5~6 glass bottles, the volume of 5~6 different coagulant concentrations to be analyzed is extracted by injection syringe and injected into each bottle. After performing rapid mixing and waiting for a sufficient mixing time, during this period, the pH value of each bottle of water is measured by a pH meter, and then a certain amount of alkali or acid is extracted by a syringe and injected into each bottle. The water sample in each bottle must reach the optimum pH range of the coagulant reaction. The mixing and agitation will be suspended, and then the quantitative volume of the coagulant will be extracted into the respective cups after being extracted by the injection syringe. At this time, after performing the slow mixing and waiting for the mixing time, the mixing and stirring are stopped, and the water is in the bottle. The suspended solids are deposited on the bottom of the bottle by natural gravity sedimentation, and after waiting for a fixed time limit, the human eye is directly observed and judged or the supernatant liquid is taken out to measure the turbidity data, and then it is determined which is the lowest turbidity. Degree of the cup and use this as the best coagulant concentration.

The disadvantage of the above artificial experimental method is that the analysis process is relatively cumbersome, resulting in a lengthy analysis process. Therefore, the analysis operation delay of the coagulant dosing amount often occurs, so that the analysis result cannot be synchronously adjusted according to the current change of wastewater quality, that is, When the concentration of suspended solids in the wastewater changes frequently, the coagulant dosing amount cannot be timely strained, resulting in an abnormal situation in which the amount of the drug is insufficient to cause water pollution or poor sedimentation effect, or the amount of dosing Excessive costs increase the cost of pharmaceuticals.

In addition, for the above-mentioned artificial bottle cup experiment process, because the general syringe is used for pumping and injecting various medicaments, the difference between the difference and the human error is increased, which increases the uncertainty of the analysis result and controls the bottle. The pH value of the water sample in the cup is stable, which also causes the manpower time to be spent in repeated dosing and measurement waiting. In addition, for the rapid analysis, the method of replacing the instrument with the “human eye” is often used as the minimum turbidity judgment of the analysis result, which leads to the analysis. The results are not accurate.

The standard range is adjusted according to the analysis result, and the high value of the concentration and the low value of the concentration.

Please refer to FIG. 4 , which is a schematic diagram showing the adjustment process of an embodiment of the present application for the reference concentration value, the high value of the concentration, and the low value of the concentration.

First, step S11 is executed, and the setting unit 41 sets the reference density value, the reference difference value, the turbidity standard range, and the count value, wherein the count value i=1, and then step S12 is performed.

In step S12, the concentration calculation unit 42 calculates a concentration high value and a low concentration value according to the set reference density value, wherein the high value is the sum of the reference concentration value and the reference difference value (ie, the high concentration value = the reference concentration) Value + reference difference value, the low value of the difference is the difference between the reference concentration value and the reference difference value (i.e., the low value of the concentration = the reference concentration value - the reference difference value), and then step S13 is performed.

In step S13, the coagulant supply control device 20 is supplied with the coagulant having a low concentration value to the first water sample reaction device 10A, and the coagulant having the concentration reference value is supplied to the second water sample reaction device 10B, and The third water sample reaction apparatus 10C supplies a coagulant having a high concentration value, and then performs step S14. In this embodiment, the coagulant supply control device 20 will be in accordance with each batch before the analysis operation is started. According to the concentration value of the coagulant to be added, it is automatically converted into the corresponding coagulant dosing pump operation seconds to achieve the addition operation of different concentrations of coagulant.

In step S14, the turbidity measuring device 16A/16B/16C measures the turbidity of the first water sample reaction device 10A/the second water sample reaction device 10B/the third water sample reaction device 10C, respectively, and outputs the first, And second and third turbidity measurement values, and respectively analyzing whether the first, second, and third turbidity measurement values meet the turbidity standard range set by the setting unit 41, and selecting to perform step S151, step S152, and step S153 And one of step S155.

In step S151, the coagulant additive concentration value analyzing device 30 analyzes that the first turbidity measurement value, the second turbidity measurement value, and the third turbidity measurement value do not meet the turbidity standard range, and then continues. Step S161 is performed.

In step S161, the count value i = i + 1 is made, and then step S171 is executed.

In step S171, it is analyzed whether the count value i is greater than 5 times. If the analysis result is i>5, the representative coagulant added concentration value analyzing device 30 has output the first turbidity measurement value and the second turbidity five times in succession. If the measured value and the third turbidity measurement value do not meet the analysis result of the turbidity standard range, step S182 is executed to stop the analysis operation and issue an abnormality warning. It should be noted that the upper limit threshold of the count value i is not limited to 5, and can be arbitrarily adjusted according to actual analysis requirements. If the analysis result is that the count value i is not greater than 5, the process proceeds to step S181.

In step S181, the parameter value adjusting unit 44 keeps the current reference density value unchanged, and causes the concentration calculating unit 42 to adjust the density high value and the low density value, wherein the low value is the reference density value and the reference difference value. Multiplied by the difference between the count values (ie, low concentration value = reference concentration value - reference difference value x i), the high value of the concentration is the sum of the reference concentration value and the reference difference value multiplied by the count value (ie, the high concentration value) = reference concentration value + reference difference × i), that is, the reference concentration value is kept constant, and the low concentration value is the reference concentration value minus The concentration after the reference difference is 2 times less, and the concentration is higher than the concentration after the reference difference is increased by 2 times, and then the process returns to step S13 to perform the analysis operation of the next batch.

It should be noted that the above step S161 is for the statistical coagulant additive concentration value analyzing device 30 to continuously output the first turbidity measurement value, the second turbidity measurement value, and the third turbidity measurement value are not consistent with the The number of times of analysis of the turbidity standard range, and the step 171 is for determining that the coagulant added concentration value analyzing device 30 continuously outputs the first, second, and third turbidity measurement values that do not meet the turbidity standard range. Whether the number of times reaches the preset number of consecutive times, thereby judging whether the analysis job is abnormal. For example, after step S181 is performed, the process returns to step S13 to perform the analysis operation of the next batch. When the analysis result of the next batch is still S151, that is, the second analysis result is the first. When the turbidity measurement value, the second turbidity measurement value, and the third turbidity measurement value do not meet the turbidity standard range, the reference concentration value remains unchanged, and the low concentration value is the reference concentration value decreased by 3 times. The concentration after the difference, and the high concentration is the concentration after increasing the reference difference by 3 times; and so on, until the fifth analysis result is still the first turbidity measurement value, the second turbidity measurement value, the When the third turbidity measurement value does not meet the turbidity standard range, the analysis result remains in the previous result, and the analysis is stopped and a warning message is issued (ie, step S181).

In step S152, the coagulant additive concentration value analyzing device 30 analyzes that at least two of the first turbidity measurement value, the second turbidity measurement value, and the third turbidity measurement value meet the turbidity standard range. Then, step S162 is continued.

In step S162, the parameter value adjusting unit 44 selects the lowest turbidity value among the first turbidity measurement value, the second turbidity measurement value, and the third turbidity measurement value that meet the turbidity standard range. The concentration value of the coagulant corresponding to one is used as the reference concentration value, and the process proceeds to step S19. In this way, the automatic analysis and change of the analytical concentration of each water sample reaction device 10A/10B/10C can be continuously obtained to obtain the most With low turbidity value, it is possible to timely change the amount of suspended solids required in the process water sample, and timely change the dosage of the required coagulant.

In step S153, the coagulant additive concentration value analyzing device 30 analyzes that the first turbidity measurement value, the second turbidity measurement value, and the third turbidity measurement value all conform to the turbidity standard range and are the same. Then step S163 is performed.

In step S163, the parameter value adjustment unit 44 maintains the current reference concentration value unchanged, that is, selects the concentration value of the coagulant added by the second water sample reaction device 10B as the reference concentration value, and the concentration high value and The low concentration values are also maintained, and then step S19 is performed. This approach results in consistently stable and identical analysis results.

In step S155, the coagulant additive concentration value analyzing device 30 analyzes that only one of the first turbidity measurement value, the second turbidity measurement value, and the third turbidity measurement value meets the turbidity standard range. Then step S165 is performed.

In step S165, the parameter value adjusting unit 44 selects the turbidity value of one of the first turbidity measurement value, the second turbidity measurement value, and the third turbidity measurement value that meets the turbidity standard range. The concentration value of the corresponding coagulant is used as the reference concentration value, and step S19 is continued.

In step S19, the count value i=1 is set, thereby terminating the statistical coagulant addition concentration value analyzing device 30 to continuously output the number of times the first, second, and third turbidity measurement values do not meet the turbidity standard range. And returning to step S12.

Please refer to FIG. 5 , which is a schematic diagram showing the adjustment process of another embodiment of the present application for the reference concentration value, the high value of the concentration, and the low value of the concentration.
