Description

Technical Field

[0001] The present application relates to the field of environmental sanitation technology, and in particular to an SV30 measuring instrument. Background Art

[0002] In the operation of sewage treatment plants, the sludge settling coefficient, or sludge settling ratio (SV), is an important indicator for observing the sludge status of aerobic systems. The sludge settling system refers to the process of quickly pouring the mixed aeration tank activated sludge mixture into a 1000ml standard measuring cylinder to the full scale, and then letting it stand for a certain period of time. The volume ratio (%) of the precipitated sludge to the taken mixed solution is a key indicator for analyzing the sludge settling performance. Usually, the ratio of the volume of the precipitated sludge after standing for 30 minutes to the volume of the taken mixed solution is selected as the sludge settling ratio, recorded as SV30. The SV30 value can reflect the amount of sludge, cohesion and sedimentation performance of the sludge during normal operation of the aeration tank. It can be used to control the discharge of residual sludge and is an important and mandatory indicator for guiding the safe and efficient operation of sewage treatment plants.

[0003] In the sewage treatment plant laboratory, the sludge sedimentation coefficient is determined by placing a standard measuring cylinder filled with 1000mL of sludge mixture in a stationary place, observing the process and characteristics of activated sludge coagulation and sedimentation, and recording at 1min, 3min, 5min, 10min, 15min, 20min, and 30min, corresponding to SV1, SV3, SV5, SV10, SV15, SV20, and SV30 respectively. The sedimentation rate before, during, and in the late stages of sludge sedimentation will be recorded in more detail, especially the observation in the first 5 minutes is the most important, and the activity of the flocculent can be understood by the rate in the early rapid sedimentation stage.

[0004] At present, the laboratory usually uses manual recording for the determination of SV30. Since the experimental determination time must reach 30 minutes and frequent recording is required, it causes a waste of human resources during the test, and often forgetfulness and wrong records cause experimental data errors. In addition, due to the limited scale of the sewage plant, there is a lack of experienced management personnel, which makes it difficult to accurately analyze the relevant test data.

[0037] Example

[0038] SV30 refers to the volume percentage of sludge in the aeration tank mixed liquid (mixed liquid refers to the mixed liquid of active microbial sludge and water) of a sewage treatment plant or sewage treatment device after it has been stationary in a 1000ml measuring cylinder and settled for 30 minutes. Because the sludge can generally reach or approach the maximum density after 30 minutes of sedimentation, this time is generally used as the standard time for the measurement. Its SV30 is an important operating indicator in the sewage treatment process. Operation management and operating personnel can find problems through the Mars sludge sedimentation process, and understand the sludge properties and aeration supply conditions from the sudden changes in the sludge sedimentation ratio, the color of the activated sludge and the floating after stationary state. The sedimentation ratio can also intuitively reflect the sludge concentration, and then indirectly reflect the load. On the other hand, the operation management personnel can determine the discharge of residual sludge by observing the sludge sedimentation ratio, thereby controlling the sludge concentration in the aeration tank, keeping the sludge load in the aeration tank in the sedimentation zone, and ensuring the effluent quality.

[0039] During the design process, the inventor discovered that SV30 is a simple method for analyzing sludge settling performance, but the existing technology requires manual measurement, including operation, reading and recording. When encountering severe weather such as heavy rain, operators are required to go out for regular inspections, which poses a serious threat to the safety of life and property of operators. At the same time, manual sampling is also prone to data omissions and misrecording, and when skilled workers leave and new workers are not properly trained, the analysis data is inaccurate.

[0040] In view of this, if Figure 1-Figure 5As shown, in the first aspect, the present application provides an SV30 measuring instrument, including: a sampling component 100, a containing component 200 and a measuring component, the sampling component 100 is connected to the containing component 200, the sampling component 100 is used to extract samples in scenes such as biochemical pools, the containing component 200 is used to measure and measure the samples extracted by the sampling component 100, and the measuring component is used to analyze and process the samples precipitated by the containing component 200, so as to ensure the accuracy of the measurement results.

The shooting component 300 continuously takes photos of the sedimentation process, and each photo represents the sedimentation status at different times, so that the data of the containing component 200 can be read more accurately, thereby improving the accuracy of the test.

[0043] In the above-mentioned implementation process, the containing component 200 is connected to the sampling structure, and the sample arrangement structure is connected to the sampling structure. When the SV30 measuring instrument is in the sampling mode, the sampling structure can extract the sample into the containing component 200 for measurement, and photograph it through the photographing component 300 and transmit it to the analysis terminal for analysis and processing. It can automatically operate the sludge sedimentation performance measurement without manual measurement, thereby improving the accuracy of the measurement results. When the SV30 measuring instrument is in the maintenance mode, the sample in the sampling structure can also be discharged from the sample arrangement structure, thereby facilitating the maintenance of the SV30 measuring instrument.

When the measuring valve 401 is a manual valve, it can prevent the sample in the containing component 201 from entering the measuring box 600 during maintenance. The injection valve 400 is connected between the containing component 200 and the sample outlet tube 105, and the measuring valve 401 is connected to the pipeline of the containing component 200, so that when the SV30 measuring instrument is in the injection mode, the conduction direction of the injection valve 400 and the measuring valve 401 is that the sample enters the containing component 200 from the injection structure, which is beneficial to the measurement of the sample and improves the accuracy of the measurement result. At the same time, the measuring valve 401 is set to prevent the sample from flowing back to the first containing pipeline 202 and the second containing pipeline 203 during the measuring process of the containing component 201.
