Description

Technical Field

[0001] This utility model relates to the field of online wastewater monitoring technology, and in particular to a wastewater detection device. Background Technology

[0002] In wastewater treatment plants, it is typically necessary to monitor and analyze various water quality indicators (pH value, ORP (Oxidation-Reduction Potential) value, nitrate nitrogen, etc.) in real time within the bioreactor. Related technologies mainly utilize online analyzers to detect and analyze these indicators. When using an analyzer, the electrodes must be submerged in the bioreactor water to a certain depth to ensure the accuracy and validity of the monitoring data. However, with the electrodes operating in wastewater for extended periods, impurities and organic matter in the wastewater will gradually adhere to and deposit on the electrode's outer surface, forming scale. This can affect the accuracy and stability of the analyzer's monitoring data and may even corrode the electrode's sealing components and penetrate into the electrode's interior, causing water ingress and corrosion damage to the internal control circuit board.

[0003] To prevent the aforementioned problems, maintenance personnel need to periodically remove the electrodes from the water tank for manual cleaning and periodically return them to the factory for replacement of the sealing components. This maintenance method requires multiple people to work together, is time-consuming and labor-intensive, and also carries a certain degree of danger. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] The following is combined with Figure 1 This invention describes a wastewater detection device.

[0033] like Figure 1As shown, this utility model provides a wastewater testing device 1, including: a water storage container 11, a sampling component 12, and a detector 13. The water storage container 11 is used to store wastewater samples. The sampling component 12 is connected to the water storage container 11 and is configured to extend into the wastewater body to collect wastewater samples and pass them into the water storage container 11. The detector 13 has a detection probe 131 that extends into the water storage container 11 to detect the water quality indicators of the wastewater samples.

[0034] In this embodiment, by setting up a sampling component 12, the sampling component 12 can extend into the sewage body (e.g., sewage in a sewage tank) to reach the required sampling depth, sample the sewage, and pass the obtained sewage sample into a water storage container 11. The water storage container 11 can hold a sufficient amount of sewage sample to meet the sampling requirements. The detection probe 131 of the detector 13 extends into the water storage container 11 to detect various water quality indicators of the sewage sample (including but not limited to pH value, ORP value, nitrate nitrogen, etc.). The water quality indicators of the sewage sample can reflect various water quality indicators of the sewage body, so that staff can analyze the water quality of the sewage body. It is understood that when maintenance personnel perform maintenance on the detection probe 131 in this embodiment, they can simply remove the detection probe 131 from the water storage container 11, making the operation more convenient and safer.

[0035] The wastewater detection device 1 of this utility model involves inserting the sampling component 12 into the wastewater body to be tested and collecting wastewater samples at a specified depth and location. A certain amount of wastewater sample is then introduced into a water storage container 11, and the detection probe 131 of the detector 13 is inserted into the water storage container 11. By detecting various water quality indicators of the wastewater sample in the water storage container 11, the water quality of the wastewater body can be analyzed. This eliminates the need for the detection probe 131 to be directly inserted into the wastewater body, requiring only contact with a small amount of wastewater sample. This helps reduce damage to the detection probe 131 from various components and impurities of the wastewater during long-term operation. It also facilitates the removal of the detection probe 131 from the wastewater for maintenance, effectively solving the shortcomings of existing water quality analyzers that require regular maintenance of the electrode probe, which is inconvenient.

[0036] Specifically, in some embodiments, such as Figure 1 As shown, the sampling assembly 12 includes a sampling tube 121 and a sampling pump 122. The inlet end of the sampling tube 121 is configured to extend into the wastewater body, and the outlet end of the sampling tube 121 is connected to the water storage container 11. The sampling pump 122 is disposed on the sampling tube 121 and is used to extract wastewater samples from the wastewater body through the sampling tube 121 and transport them to the water storage container 11.

[0037] In this embodiment, the sampling tube 121 is used to extend into the sampling position of the sewage body. The sampling tube 121 is equipped with a sampling pump 122, which is used to provide suction force so that the sewage is pumped into the water storage container 11 through the sampling tube 121 as a sewage sample for the detector 13 to perform detection.

[0038] In some embodiments, such as Figure 1 As shown, the sampling assembly 12 also includes a filter head 123, which is disposed at the inlet end of the sampling tube 121 and is used to filter out solid impurities in the sewage.

[0039] In this embodiment, a filter head 123 is provided at the inlet end of the sampling tube 121. The filter head 123 includes a filter structure such as a filter screen, which allows sewage to pass through while preventing solid impurities in the sewage from entering the sampling tube 121. It can be understood that these solid impurities are not the main detection targets of the sewage detection device 1 and have little impact on water quality indicators. On the contrary, they may adhere to the detection end of the detection probe 131, thereby affecting the detection results. The filter head 123 of the sampling tube 121 prevents these solid impurities from entering the water storage container 11 through the sampling tube 121 and affecting the detection data.

[0040] In some embodiments, such as Figure 1 As shown, the wastewater testing device 1 also includes an overflow pipe 14. The water storage container 11 is provided with an inlet and a outlet. The inlet is connected to the outlet end of the sampling pipe 121, and the outlet is connected to the overflow pipe 14. The overflow pipe 14 is used to discharge wastewater samples.

[0041] In this embodiment, an inlet and an outlet are respectively provided on the water storage container 11. The inlet is used to receive the sewage sample introduced by the sampling tube 121. When the sewage sample in the water storage container 11 reaches a certain amount, it can overflow into the overflow pipe 14 through the outlet and be discharged. This allows the sampling component 12 to continuously collect sewage samples and continuously introduce new sewage samples into the water storage container 11. Old sewage samples are discharged from the outlet, so that the sewage detection device 1 can continuously detect various water quality indicators of the sewage body, which is convenient for staff to monitor the dynamic changes of various water quality indicators of the sewage body.

[0042] Understandably, overflow pipe 14 can discharge sewage back into the sewage body being tested.

[0043] It is understandable that the sampling tube 121 can be divided into two sections. One section of the sampling tube 121 is connected to the inlet of the sampling pump 122 and is used to extend into the sewage body. The other section of the sampling tube 121 is connected to the outlet of the sampling pump 122 and is connected to the inlet of the water storage container 11.

[0044] Specifically, in some embodiments, the sampling pump 122 is a peristaltic pump. In this embodiment, by setting the sampling pump 122 as a peristaltic pump, when the peristaltic pump draws fluid, the fluid only contacts the pump tube and does not contact the mechanical structure inside the pump body. This avoids the penetration and corrosion of the mechanical structure inside the pump body by sewage when drawing sewage, making it more stable and reliable.

[0045] In some embodiments, the detector 13 includes a cabinet 132, a detection probe 131, and a processor 133. The detection probe 131, the processor 133, and the sampling pump 122 are all installed in the cabinet 132. The processor 133 is connected to the detection probe 131 and is used to acquire detection data of water quality indicators of the wastewater sample based on the detection signal fed back by the detection probe 131.

[0046] In this embodiment, it is understood that the detection probe 131 is typically an electrode probe. When the detection probe 131 comes into contact with the water, it generates a corresponding electrical signal (i.e., a detection signal) and transmits the electrical signal to the processor 133. The processor 133 can acquire the detection data of the corresponding water quality indicators based on the electrical signal. It is understood that the processor 133 can be connected to a display device or a host computer to transmit the detection data of the water quality indicators. The display device is used to display the detection data, and the host computer can be used to record the detection data for staff to review and analyze. Simultaneously, a cabinet 132 is provided, which houses the detection probe 131, the processor 133, and the sampling pump 122, allowing staff to move the wastewater detection device 1 as needed. Specifically, when the entire wastewater detection device 1 needs to be moved, staff only need to connect the pipes extending into the wastewater (such as the sampling pipe 121 and the overflow pipe 14) and then move the cabinet 132 to the target location.

[0047] Alternatively, in some embodiments, such as Figure 1 As shown, the water storage container 11 is installed on the outside of the detection probe 131, and a detection hole is provided corresponding to the detection end of the detection probe 131 so that the detection end of the detection probe 131 can extend into the water storage container 11.

[0048] In this embodiment, the water storage container 11 is directly installed on the outside of the detection probe 131 and the detection end of the detection probe 131, so that the detection end of the detection probe 131 can extend into the water storage container 11 through the detection hole on the water storage container 11 to contact the sewage sample in the water storage container 11 and perform detection.

[0049] Specifically, in some embodiments, such as Figure 1As shown, the water container 11 is fitted onto the outside of the detection end of the detection probe 131. In this embodiment, the water container 11 can be directly fitted onto the detection end, so that the detection probe 131 itself can support the water container 11, making it convenient to assemble and disassemble the water container 11.

[0050] Furthermore, in one specific embodiment, such as Figure 1 As shown, the detection probe 131 is cylindrical, and the detection end of the detection probe 131 is located on the outer peripheral wall of the detection probe 131. The water storage container 11 has a mounting hole that is adapted to the detection probe 131. The detection probe 131 passes through the mounting hole and the detection end of the detection probe 131 extends into the water storage container 11.

[0051] Specifically, in some embodiments, the volume of the water storage container 11 is not less than 0.3L and not more than 0.5L. In this embodiment, by setting the volume of the water storage container 11 to 0.3L~0.5L, the sewage sample contained in the water storage container 11 can meet the detection requirements of the detector 13, while minimizing the volume and space occupied by the water storage container 11.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
