Description

Technical Field

[0001] The present invention relates to the technical field of activated sludge test and analysis, and specifically provides an activated sludge denitrification and phosphorus removal performance test and analysis device. Background Art

[0002] An activated sludge denitrification and phosphorus removal performance test and analysis device is a device used to evaluate and monitor the effect and performance of activated sludge in denitrification and phosphorus removal during the sewage treatment process. In an environment such as a food factory, it is very important to treat nitrogen and phosphorus in wastewater because excessive nitrogen and phosphorus can cause eutrophication of water bodies and affect the ecological environment. Among them, sewage treatment technologies include core technologies such as online variable structure neural network sludge concentration SV turbidity prediction, falling condition classification and health assessment, and multi-objective parameter optimization methods. At the same time, the water quality management control system includes building a set of online monitoring soft measurement instruments for sludge activity and water quality, which can detect no less than 3 water quality parameters and sludge activity-related parameters.

[0003] In the prior art, the Chinese patent with the publication number "CN210465371U" discloses an activated sludge denitrification and phosphorus removal performance test and analysis system. The container is connected to the sludge sampling device, and the mechanical device is used to complete the transportation of activated sludge from the sludge storage tank to the container, reducing the manual work intensity and facilitating automated fine management. The container is connected to the water inlet device, and at the same time, a sewage discharge pipe is arranged on the container, simplifying the sludge washing operation and device cleaning operation, and improving the work efficiency. The setting of the automatic timing sampling device saves a lot of time for the staff, and at the same time makes the sampling operation more precisely controllable and convenient for comprehensive management, reducing the sampling error rate and delay rate, and solving the problems that the existing equipment is inconvenient for sludge inlet, because there is no sludge sampling device, and the device itself is large in volume, requiring manual handling and pouring of sludge into the reaction container, which is time-consuming and laborious, and the sludge cleaning work requires additional devices.

[0004] In the above-described solution, when stirring the sludge and the drug in the container, only a stirring blade with a fixed position and unable to change its shape is used to stir the sludge and the drug. This stirring blade can only stir a single position. Although the centrifugal force can be used to mix the reactants in the container, the mixing effect is not good, which will affect the efficiency of the entire device. At the same time, during the cleaning process of the container, only water is added to the container through the cleaning water, and the cleaning function is completed by the mixing of water and sludge. Since the sludge will adhere to the inner wall, excessive water needs to be added to contact the sludge, which will cause excessive waste of water resources. Summary of the Invention

[0023] Working principle: During use, by starting the sludge pump 5, the sludge in the storage cylinder 2 is discharged into the reaction tank 1 through the input pipe 6 and the discharge pipe 7. Then, a certain amount of ammonium chloride and sodium bicarbonate are respectively added to the reaction tank 1 in sequence through the existing dosing device. The dosing amounts of the added drugs are adjusted according to the results of the on-line pH meter and the on-line ammonia nitrogen tester for real-time monitoring to ensure that the initial ammonia nitrogen concentration is similar to the actual influent concentration and the pH value meets the alkalinity requirements of the nitrification process. Regular sampling is completed according to the regular sampler 9. Then, the test samples in the centrifuge tube 11 are detected according to the phenoldisulfonic acid spectrophotometry (GB7480-1987) for the determination of nitrate nitrogen in water quality. A linear regression is performed according to the change of nitrate nitrogen concentration in the mixed liquid (with time as the abscissa and nitrate nitrogen concentration as the ordinate), and the nitrification curve of the sludge system can be obtained. Then, the nitrification rate of the system can be calculated based on the sludge concentration of the sludge system. When it is necessary to stir the sludge and medicine in the reaction tank 1, the first electric push rod 22 drives the adjusting plate 23 to descend. The adjusting plate 23 will cooperate with the U-shaped frame 26 on the connecting cross bar 20 through the adjusting rod 25 in the rotating groove 24, so that the connecting cross bar 20 cooperates with the reset shaft 29 and the reset groove 28, so that the connecting cross bar 20 rotates around the reset shaft 29, causing the connecting cross bar 20 in the horizontal state to rotate at an angle. Through the cooperation of the connecting cross bar 20 and the cleaning arc plate 21, a stirring member is formed. Then, the hydraulic cylinder 13 reciprocally drives the positioning plate 35 to reciprocally lift and lower. By utilizing the cooperation of the screw rod 14 and the bearing 36, and the cooperation of the screw rod 14 and the screw hole 16, the connecting cross bar 20 and the cleaning arc plate 21 can be driven to reciprocally lift and rotate in the cement tank. Through the connecting cross bar 20 and the cleaning arc plate 21, the sufficient reaction between the sludge and the medicine in the reaction tank 1 can be effectively ensured; After the reactants in the reaction tank 1 are discharged, in order to prevent the residues in the reaction tank 1 from affecting the new test of the sludge, there is no need to adjust the angle of the connecting cross bar 20. At this time, the connecting cross bar 20 and the cleaning arc plate 21 form a cleaning member. Water is added to the reaction tank 1 through an external water pipe. After adding a certain amount of water, the hydraulic cylinder 13 reciprocally drives the positioning plate 35 to reciprocally lift and lower. By utilizing the cooperation of the screw rod 14 and the bearing 36, and the cooperation of the screw rod 14 and the screw hole 16, the connecting cross bar 20 and the cleaning arc plate 21 can be driven to reciprocally lift and rotate in the cement tank. By making the cleaning arc plate 21 fit with the inner wall of the reaction tank 1, the sludge adhering to the inner wall of the reaction tank 1 is shed. The shed sludge will be mixed with the water in the reaction tank 1 and finally discharged through the sewage pipe; In order to make the stirring effect of the stirring member formed by the connecting cross bar 20 and the cleaning arc plate 21 better, the second electric push rod 33 drives the second connecting frame 34 to move horizontally on the connecting cross bar 20. The second connecting frame 34 will cooperate with the first connecting frame 31 through the pulling rod 32, so as to pull the secondary arc plate 2103 to rotate at an angle on the main arc plate 2101. By changing the shape of the cleaning arc plate 21, a new stirring member is formed by the cleaning arc plate 21 and the connecting cross bar 20.
