Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, specifically an integrated sampling and sedimentation performance measurement system for anaerobic reaction towers. Background Technology
[0002] Anaerobic reactors are the core equipment for wastewater treatment, and their operating status directly affects the treatment effect. One of the key methods to monitor the operating status of anaerobic reactors is to periodically collect sludge samples from different heights inside the reactor and analyze their sludge concentration and sludge settling ratio.
[0003] The current conventional sampling method involves operators collecting samples from different sampling points on the anaerobic tower wall into individual sampling bottles or beakers, and then bringing them back to the laboratory or conducting SV30 sedimentation experiments on-site. This traditional method has many drawbacks:
[0004] 1. Cumbersome and inefficient operation: It requires opening the sampling valve multiple times, cleaning the sampling container, and transferring the sample to a graduated cylinder for SV30 measurement.
[0005] 2. Sample representativeness is easily distorted: During the sample transfer process, its properties may be altered due to spillage, evaporation, or excessive contact with air, affecting the accuracy of the measurement results.
[0006] 3. Safety hazards exist: biogas and hydrogen sulfide produced during the anaerobic digestion process may escape with the samples and accumulate in the laboratory operating area, posing a risk of combustion, explosion or poisoning.
[0007] 4. Difficulty in synchronous comparison: Sampling and measuring at different heights results in time differences, making it difficult to accurately compare the sludge state at different levels within the tower at the same time point. Utility Model Content
[0008] To overcome the above-mentioned defects, this utility model provides an integrated sampling and sedimentation performance measurement system for anaerobic reaction towers, which solves the problems of cumbersome operation and the fact that the properties of samples are altered due to spillage, volatilization or excessive contact with air during sample transfer, thus affecting the accuracy of the measurement results.
[0009] To achieve the above objectives, this utility model provides the following technical solution: an integrated sampling and settling performance measurement system for an anaerobic reaction tower, comprising an anaerobic reaction tower body, a sampling tube unit, a sampling water tank, and a graduated settling tube. One side wall of the anaerobic reaction tower body is fixedly connected to the sampling water tank. The sampling tube unit includes sampling tube one, sampling tube two, and sampling tube three. Sampling tube one, sampling tube two, and sampling tube three are fixedly connected to the anaerobic reaction tower body, and sampling tube one, sampling tube two, and sampling tube three are all led down from top to bottom along the inner wall of the anaerobic reaction tower body, with the lower end outlet extending to the outside through an opening.
[0010] Sampling valves are installed at the ends of sampling tubes 1, 2, and 3 that extend out of the anaerobic reaction tower. Multiple partition plates are connected inside the sampling tank. The opening of the sampling tank is divided into multiple sampling areas by the partition plates, and an outlet is provided below each sampling area. The graduated sedimentation tube is a transparent tube with volume graduations on its wall. The upper end of the graduated sedimentation tube is connected to the outlet below the sampling area of the sampling tank. An air drain valve is installed at the lower end of the graduated sedimentation tube, and a drain pipe is connected to the lower end of the graduated sedimentation tube through the air drain valve.
[0011] As a further embodiment of this utility model: the sampling tube one, sampling tube two and sampling tube three are arranged at different heights at one end of the anaerobic reaction tower and are arranged in descending order of height. The multiple sampling areas on the sampling tank correspond sequentially to the ends of the sampling tube one, sampling tube two and sampling tube three that extend out of the anaerobic reaction tower.
[0012] As a further embodiment of this utility model: the sampling tube 1, sampling tube 2 and sampling tube 3 extend from one end of the anaerobic reaction tower body and bend downwards at a height of 1.2 meters above the ground, and the capacity of the graduated settling tube is 1000mL.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a sampling tube unit, a sampling tank, a graduated settling tube, a sampling valve, a drain valve, and a drain pipe, the sludge samples in the anaerobic reaction tower are allowed to flow into the sampling area on the sampling tank by slowly opening the sampling valves at one end of sampling tube one, sampling tube two, and sampling tube three in sequence. Then, the drain valve is closed, causing the sludge samples in the sampling tank to fill the graduated settling tube to the highest mark, allowing it to settle. The sludge settling interface is directly observed through the transparent wall of the graduated settling tube, and the settling volume is recorded. Finally, the drain valve is opened to drain the waste liquid and sludge in the graduated settling tube. The tubes are completely emptied, and then the sampling point and measurement point are integrated into one unit through the integrated connection between the sampling water tank and the graduated sedimentation tube. After sampling, the sedimentation experiment can be carried out directly without transferring the sample, eliminating sample loss and property changes during the transfer process. The measurement results are more accurate and reliable. Furthermore, samples can be extracted simultaneously from different heights inside the anaerobic reactor through sampling tubes one, two, and three of different heights and collected in the sampling water tank for synchronous sedimentation comparison. The entire sampling and measurement process is carried out in the sampling water tank, which reduces the risk of biogas escaping from the anaerobic reactor and simplifies the operation steps, making subsequent emptying and cleaning easier.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0019] like Figure 1-3 As shown, this utility model provides a technical solution: an integrated sampling and settling performance measurement system for an anaerobic reactor, including an anaerobic reactor body 1, a sampling tube unit 2, a sampling water tank 4, and a graduated settling tube 6. One side wall of the anaerobic reactor body 1 is fixedly connected to the sampling water tank 4. The sampling tube unit 2 includes a first sampling tube 201, a second sampling tube 202, and a third sampling tube 203. The first sampling tube 201, the second sampling tube 202, and the third sampling tube 203 are fixedly connected to the anaerobic reactor body 1, and each of the three sampling tubes extends downwards along the inner wall of the anaerobic reactor body 1 from top to bottom, with the lower outlet extending outwards through an opening. Sampling valves 3 are installed at one end of the anaerobic reaction tower body 1. Sampling tubes 1 201, 202, and 3 203 are arranged at different heights inside the anaerobic reaction tower body 1, and are arranged in descending order. Multiple sampling areas on the sampling tank 4 correspond to the ends of sampling tubes 1 201, 202, and 3 203 that extend out of the anaerobic reaction tower body 1. The upper inlets of sampling tubes 1 201, 202, and 3 203, which are at different heights, are located at three different heights inside the anaerobic reaction tower body 1, namely the upper, middle, and lower parts. This allows for simultaneous sampling of different reaction areas inside the anaerobic reaction tower body 1, so that the samples from each layer naturally flow into the corresponding sampling area of the sampling tank 4, avoiding monitoring deviations caused by single-point sampling.
[0020] The sampling tank 4 is internally connected to multiple partition plates 5. The opening of the sampling tank 4 is divided into multiple sampling areas by the partition plates 5, and each sampling area has an outlet below it. The graduated sedimentation tube 6 is a transparent tube with volume graduations on its wall. The upper end of the graduated sedimentation tube 6 is connected to the outlet below the sampling area of the sampling tank 4. The lower end of the graduated sedimentation tube 6 is equipped with a drain valve 7, and the lower end of the graduated sedimentation tube 6 is connected to a drain pipe 8 through the drain valve 7. Sampling tube 1 201, sampling tube 202, and sampling tube 3 203 are also included. One end of the anaerobic reaction tower 1 is bent downwards at a height of 1.2 meters above the ground. The graduated settling tube 6 has a capacity of 1000 mL. Through multiple partitions 5 in the sampling tank 4, the samples transported by sampling tube 1 201, sampling tube 202 and sampling tube 3 203 are isolated in independent sampling areas, which effectively avoids cross-contamination of samples. In addition, the direct connection between the outlet of the sampling area below the sampling tank 4 and the graduated settling tube 6 allows the sample to flow naturally into the graduated settling tube 6 by gravity, which simplifies the operation process.
[0021] The working principle of this utility model is as follows:
[0022] First, slowly open the sampling valves 3 at one end of sampling tube 1 (201), sampling tube 2 (202), and sampling tube 3 (203) in sequence, so that sludge samples at different heights in the upper, middle, and lower parts of the anaerobic reaction tower 1 flow into the sampling area on the sampling tank 4. During the process, close the drain valve 7 to allow the sludge samples in the sampling tank 4 to fill the graduated settling tube 6 to the highest mark, and then close the sampling valve 3. After that, let it settle, and observe the sludge settling interface directly through the transparent tube wall of the graduated settling tube 6, and record the settling volume and data. Finally, open the drain valve 7 to drain all the waste liquid and sludge in the graduated settling tube 6 through the drain pipe 8.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
