When the slot is not long-term or vertical reading, the position and number of the measuring device can also be set according to the actual setting. Μ Experiment=1 Vertical measurement of the concentration of ss in the water incident on the horizontal laser source. Please refer to Section 3®, which is a schematic diagram of the direct exposure of the horizontal laser source to the incident tilted water (IV). In order to measure the SS concentration in water, the operator cuts the water·New Age into a plurality of cuboids. In Fig. 3, the binary number = rectangular unit 1 to 4 whose square body is _ size. The beam lQ is horizontally injected into the water camera above the water body. Scattered water_image.

Then, establish the relationship between absorbance and SS concentration, and write this relationship into the NlL.abView graphical program tone program towel to monitor the concentration of (IV) material. When the number of rectangular units is N, the strength of the Nth unit is "unit wear ^ N klox unit scattering rate X unit transmittance n = n", and the unit transmittance is · ^. Experiment 1 of Experimental Example 1 The water body of the test 1 is a fixed water level height and is an artificially disposed high concentration of high-soil solution, and the high-resistance solution component is stable and is f, as a fresh product of the standard water f. The horizontal laser source is injected into the ridge solution, and the camera shoots the water image vertically at different heights from the water surface to measure the absorbance and SS concentration. The results are shown in Fig. 4. 201111763 When the distance from the water surface is fixed, the kaolin solution concentration is positively correlated with the absorbance. If the concentration of the specific kaolin solution is taken as the target, the absorbance decreases nonlinearly with increasing distance from the water surface. Therefore, the relationship between the ss concentration and the concentration of the actual water body can be calculated by the relationship between the absorbance and the distance from the water surface. Experiment 2 of Experiment 1 Experiment 2 also uses a kaolin solution as a water body to measure the ss concentration by vertically shooting a horizontal laser light source into the water. The result is shown in Fig. 5, and the absorbance is positively correlated with the ss concentration, which can reflect the actual The status of water quality changes, and provide real-time information based on actual water quality changes, to achieve automatic control and immediate monitoring purposes. In addition, the measurement method of Experiment 2 can also calculate the turbidity of water. Please refer to Figure 6, which is a graph showing the relationship between absorbance and turbidity. The results show that the absorbance is positively correlated with turbidity. The function is corpse 1 and +〇〇〇79, and the correlation coefficient is R2 = 0.9363. Experiment 1 of Experiment 1 3 Experiment 3 uses a continuous-flow sequential batch reactor (CFSBR) discharge water as a water body in a wastewater treatment plant, and adjusts the length of the unit centimeters (ie, a rectangle) The width of the unit), the vertical concentration of the horizontal laser light source is measured by the water source. The transmittance of the laser beam is calculated according to the intensity of the laser scattered light caused by the laser source and ss. With absorbance' the results are shown in Figure 7®. At the same concentration, the length of the unit centimeter is proportional to the absorbance. It is confirmed that the calculation of the absorbance is in accordance with Lambert Beer's law, and the law becomes the theoretical basis for measuring the SS concentration. Please refer to FIG. 8 , which is a graph showing the relationship between the SS concentration of the CFSBR real discharge water and the absorbance of the 6 cm optical path length of Experiment 3 of the experimental example i of the present invention, and FIG. 8 is the experimental data of the ^ cm diameter of the second figure. In Fig. 8, the top and bottom ends of each vertical line represent the high and low values of the water quality measurement error range, the average value of the midpoint of each vertical line, and the solid triangle symbol (▲) is SS. The absorbance of the error range and the 201111763 symbol indicates the average of the water quality. It can be seen from Fig. 8 that the discharge water having a relatively low SS concentration has a good sensitivity. The absorbance gradually increases with the SS concentration. Therefore, the i measurement method of the example i can be applied not only to homogeneous and stable water bodies (such as kaolin solution), but also to heterogeneous water bodies (such as wastewater treatment plant discharge water).

Ss concentration relationship. Please refer to the first diagram, f. The kaolin ss concentration of experiment 1 of experiment 1 has no luminosity correlation. The nonlinear function correlation coefficient of the ίο diagram is 0989986, which proves that the vertical laser source can be utilized. The ratio of the attenuation of the political light to the transmittance and the absorbance are calculated. When the concentration of the kaolin solution increases, the turbidity of the water can be calculated. Please refer to Figure 11 for the turbidity and absorbance of the kaolin solution. Fine, confirming that the absorbance is positively correlated with turbidity' For y = _G G(8), delete χ 议 G482x + 0.000648, correlation coefficient r2 = 0.982297. Lu also, and analyze the relationship between different concentrations of kaolin solution and absorbance, the results are shown in Figure 12. According to the standard water quality test method, ss concentration The percentage of measurement error is 20% below 25 mg/L, and the above is 1〇%. The error range is plotted as the upper and lower limits of the water shell analysis. The sample center line is the water quality analysis result, and the top and bottom of the block are possible mis-wires. The concentration estimated by experiment i in experiment example 2 is the square of the square line from the two ends of the center line. The top and bottom ages of the square are overestimated and underestimated. The actual water quality is analyzed by the actual image (10). Results. It can be seen from Fig. 12 that the ss concentration measured by different concentrations of kaolin solution can reflect the change of actual water quality. The actual example _^Experiment 2 The inspection 2 uses the activated sludge domesticated by the CFSBR mold factory. For the research object, CFSBR will pass the influent wastewater through the anaerobic phase, aerobic phase, anoxic phase, re-exposure phase, and shoal, and process it into a discharge water that meets the discharge standard. Generally speaking, it is boring. Oxygen phase procedure After the Shen Dian drainage phase program, the activated sludge can be uniformly mixed after a period of time. The SS concentration of the anaerobic phase is between 3000 and leaking mg/L. The aerobic phase is subjected to agitation and aeration to make the precipitate at the bottom. Large activated sludge Yang 12 201111763 , the aerobic phase SS concentration is between 5000~8000 mg / L; the anoxic phase program is in good milk, after the procedure, because the sedimentation sludge has been raised, and lack of aeration The process, for the more stable nature, the SS concentration of the anoxic phase is between 5000 and 7000 mg/L. ^ In Experiment 2, the measuring device is erected above the CFSBR mold factory, the anaerobic phase, the aerobic phase and the anoxic phase. The water body was subjected to 5 cycles, and the anaerobic phase, the aerobic phase, and the anoxic phase ss concentration of the vertical laser source were vertically photographed. The results are shown in Fig. 13 (8) to Fig. 13 (_, absorbance and The ss concentration is silky. According to the relationship established by each phase, as the CFSBR mold factory, each operation phase of each cycle is condensed, and the mother cycle is about 10 hours. The absorbance and SS concentration are measured. The estimated SS concentrations are all in the 1%% error range of the manual analysis. The average errors of the anaerobic phase, the aerobic phase, and the anoxic phase are 9.21%, 8.06%, and 7.43%, respectively. Therefore, the measurement of the water SS concentration in Experiment 2 of Experimental Example 2 is not only feasible but correct. The more stable the nature of the activated sludge, the smaller the error in the results obtained by the method of the present invention and the results of the manual analysis. In addition, the discharged water treated by the above CFSBR mold factory is introduced into a transparent tank body (volume 30 cm X 2〇cm X 20 cm), and the tank body is horizontally incident with a 650 mn laser light source, and the scattered light of the horizontal laser light source is vertically photographed. Intensity image, calculate the penetration rate ^ (measurement method as shown in the experimental example!)' The results are shown in Figure 14, which is treated by the anaerobic phase, aerobic phase, and anoxic equalization process. The discharged water conforming to the discharge standard, the SS concentration of the discharged water is low, and the ss property after treatment is in the nature of the SS of the sister. The ss after the manual analysis is prone to error (standard range = error range of 2G%) Therefore, the correlation coefficient shown in Figure 14 is 6312 lower than the discharge water with high SS inversion. Fine, for the discharge water, the result of 帛14 _ is also positively correlated with the SS concentration of the discharged water.
