Description

Technical Field

[0001] The present invention relates to the technical field of sewage detection, in particular to a sewage purification quality monitoring device. Background Art

[0002] Sewage refers to domestic and production water that has been polluted to a certain extent. Sewage often contains certain impurities that cause it to be discharged after use. Sewage not only contains a large amount of garbage and sediment, but also often contains a large amount of harmful substances. Since sewage is polluted, it is easy to cause environmental pollution if it is discharged directly. It is not only easy to produce surface runoff, contamination erosion and farmland pollution, but also to pollute groundwater and drinking water sources. Therefore, sewage needs to be purified before it can be discharged.

[0003] During the sewage purification process, not only the impurities need to be filtered, precipitated and decomposed, but there are also certain standards for the water-soluble dissolved substances contained in the sewage. Only sewage with various substance contents that meet the discharge standards can be discharged. Therefore, in the purification process, it is necessary to test the content of various substances in the sewage in each link. When sewage is purified, a sewage pool is used for purification. Before discharge, it is necessary to test the different substances in each water layer in the sewage pool to determine the substance content of each water layer in the current sewage pool, and thus determine what measures are needed for further purification.

DETAILED DESCRIPTION

[0034] This embodiment is described in detail with reference to the accompanying drawings.

[0035] When this embodiment is in use, the sewage is first filtered and chemically purified and biologically purified before being output. The purified water flows through the sewage purification tank 1 for transition and is further precipitated in the sewage purification tank 1. At the same time, the purified water quality is tested in the sewage purification tank 1 to determine whether the purified water meets the discharge standard and the contents of various substances in different water layers. If the test result does not meet the standard, the error is determined by accurately testing the various substances in the test result, and then the test step is checked to ensure that the discharged sewage meets the discharge standard.

[0036] A vertically arranged lifting threaded rod 2 is fixedly connected in the sewage purification tank 1. There are two lifting threaded rods 2 that are arranged vertically in parallel. A driving motor for driving the lifting threaded rod 2 is provided at the upper end of the lifting threaded rod 2. A horizontally arranged detection piece is threadedly connected to the lifting threaded rod 2. The lifting threaded rod 2 is driven by the rotation of the driving motor. The upper ends of the two lifting threaded rods 2 are connected by a synchronous belt to adjust the height of the detection piece on the lifting threaded rod 2. The outer side surface of the detection piece is threadedly connected to one of the lifting threaded rods 2. When the detection piece is lifted to different heights corresponding to each water layer, the water quality in the current water layer is detected and sampled for retention.

[0037] The detection component includes a detection shell 3, which is a hollow and closed structure, wherein a horizontally arranged water channel 4 is opened on the detection shell 3 to allow water to pass through, and the two ends of the water channel 4 are respectively consistent with the flow direction of the water flow in the purification pool, so that the water flows through the detection component from one end of the water channel 4 and then flows out from the other end. A closing cover is rotatably connected to the outer side of the water inlet end of the water channel 4. In the initial position, the closing cover closes the end of the water channel 4. When water passing is required, the closing cover is opened so that water can pass through the water channel 4. At the same time, when the surface water layer is not collected and the underwater water quality is directly collected, the closing cover can prevent surface debris and oil film from entering the water inlet channel, thereby affecting the accuracy of the detection result. In the process of water flowing through the water channel 4, the water quality is detected by the detection structure in the detection component and samples are stored in different areas.

[0038] An annular channel 5 is provided in the detection housing 3 in the same plane as the water passage 4. The annular channel 5 is located in the middle of the water passage 4 and is arranged alternately with the water passage 4. A separation ring 6 is coaxially rotatably connected in the annular channel 5. The separation ring 6 and the annular channel 5 are sealed and rotatably connected to prevent water from overflowing from the side of the separation ring 6 when the separation ring 6 rotates. The separation ring 6 is respectively provided with a first through hole 16 that is horizontally connected and matches the water passage 4. Under normal circumstances, water flows into one end of the water passage 4, and then flows through the first through hole 16 and is discharged from the other end, wherein the first through hole 16 does not block the water flow. The first through-hole 16 on the separation ring 6 is evenly spaced apart on its side with a plurality of vertically penetrating second through-holes 17, a water inlet 18 is arranged outside the second through-hole 17 and a water outlet 19 is arranged at the inner upper end. When the detection housing 3 moves downward to the set position for sampling and detection, the separation ring 6 is driven by the driving motor. When the separation ring 6 rotates, the second through-hole 17 adjacent to the first through-hole will rotate to the position corresponding to the position of the water passage 4. At this time, when the water flows through the water passage 4, the water will flow from the water inlet 18 outside the second through-hole 17. The water flows into the second through-hole 17, and the air in the second through-hole 17 is discharged from the water outlet 19 at the upper end of the inner side surface. Since the water outlet 19 is located at the upper end, the air will not remain in the second through-hole 17. The water flow will fill the corresponding second through-hole 17, so that the second through-hole 17 is filled with the liquid in the current water layer, and then the separation ring 6 is controlled to continue to rotate. When the separation ring 6 continues to rotate, the corresponding adjacent second through-hole 17 is controlled to rotate to the position corresponding to the water-passing channel 4, and the second through-hole 17 that has been filled with liquid will rotate into the annular channel 5. Since the annular channel 5 is connected to the water-passing channel 4, the water flows into the corresponding second through-hole 17. The separation rings 6 are sealed and rotatably connected, so the second through-port 17 that has been filled will carry the liquid into the annular channel 5 until the second through-port 17 filled with liquid rotates to the position of the drain port 8 opened in the annular channel 5 and stops. At this time, the liquid in the current through-port can be discharged and collected through the drain port 8, and the detection shell 3 moves downward to the next water layer and then stops. At this time, another second through-port 17 corresponds to the water channel 4. The above actions are repeated to fill each second through-port 17 in turn, and at the same time, the liquids in different water layers are collected and stored separately.

[0039] After the through-port corresponds to the discharge port 8, the liquid is discharged. An annular storage member 9 is coaxially connected to the annular channel 5. The storage member 9 is provided with a plurality of storage chambers 10 evenly distributed around the circumference. Each storage chamber 10 is provided with a liquid inlet 11 at the upper end thereof for liquid to enter the storage chamber 10, so that the liquid located in the second through-port 17 enters the storage chamber 10. An air suction port 12 is provided at the upper end of the outer surface of the storage member 9 corresponding to the position of the storage chamber 10. The air in the storage chamber 10 is discharged through the air suction port 12. After the air in the air suction port 12 is discharged, a negative pressure is formed in the air suction chamber. The liquid in the second through-port 17 located above is sucked into the storage chamber 10 for storage by the liquid inlet 11 at the upper end of the storage chamber 10. Since the air suction port 12 is located at the upper end of the outer surface of the storage member 9, the liquid will not be sucked out when the liquid height in the storage chamber 10 does not exceed the air suction port 12 during suction.

[0040] A plurality of seepage heads 15 are provided on the inner side surface of the storage component 9. The number of the seepage heads 15 is the same as the number of the storage chambers 10 and the seepage heads 15 are evenly distributed around the circumference. The seepage heads 15 are spirally distributed on the inner side surface of the storage component 9. The height differences between adjacent seepage heads 15 are the same. The seepage heads 15 cause the liquid in the storage chamber 10 to seep outward along the seepage heads 15. The seepage principle is the same as that of an ink pen, so that the seepage heads 15 are contacted with a test paper for detection. After the liquid enters the storage chamber 10, as the storage component 9 rotates, the liquid inlet 11 is disengaged from the liquid discharge port 8, and the air suction port 12 is also rotated to be disengaged from the air suction pump position. At this time, a closed space is formed in the storage chamber 10. During the process of liquid seeping out of the seepage heads 15, the liquid can only be discharged outward through contact and will not flow out along the seepage heads 15.

[0041] A sampling detection member detachably connected to the lower end of the detection shell 3 is provided in the space inside the storage member 9, and the sampling detection member includes a plurality of sampling disks 13 evenly spaced vertically, and the spacing between adjacent sampling disks 13 is the same as the height difference between adjacent water seepage heads 15, so that each sampling head corresponds to and contacts one of the sampling disks 13, and the sampling disk 13 is annular, and a plurality of sector-shaped detection areas 14 are evenly distributed on the circumference of the sampling disk 13, and the sampling head contacts the outer edge of the sector-shaped detection area 14, and each sector-shaped detection area 14 is detachably connected with a test paper for accurate detection of different substances, so that during the rotation of the storage member 9, the liquid in the storage cavity 10 contacts each sector-shaped detection area 14 through the water seepage head 15 and the detection result is stored, so that the detection result is taken out after the detection is completed, and the liquid in each storage cavity 10 is taken out and stored.

[0042] A turbidity detection member for detecting the turbidity of the liquid passing through the water passage 4 is provided at the upper end of the detection housing 3. The turbidity detection member includes a detection rotating rod 21, which is rotatably connected in the detection housing 3. The detection housing 3 extends downward into the water passage 4. A detection water passage notch perpendicular to the axis of the detection housing 3 is provided on the detection housing 3. A detection notch 22 perpendicular to the axis of the detection rotating rod 21 and having a vertical structure is provided on the detection rotating rod 21. The detection water passage notch corresponds to the detection notch 22, so that when no detection is required, the detection water passage notch and the detection notch 22 are arranged alternately, so that the liquid does not enter the detection area. When the detection is performed, the detection water passage notch and the detection notch 22 overlap, so that the liquid passes through the detection area and is detected. The detection area is an area located between the upper and lower ends of the detection rotating rod 21. A light source and a light receiving member are respectively provided at the upper and lower ends of the detection rotating rod 21. When the detection light passes through the area between the light source and the light receiving member, the turbidity of the liquid is judged by the feedback of the light in the light receiving member.

[0043] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
