[0002] With the rapid development of industrialization and urbanization, the importance of water quality monitoring in drainage systems has become increasingly prominent. Fatty acids are key components that are widely present and active in sewage. The accurate determination of their content is crucial to evaluating the performance of sewage treatment plants, optimizing treatment processes, and formulating pollution prevention and control strategies.

[0003] Existing fatty acid content determination technologies mostly rely on laboratory offline analysis equipment. These devices usually use specific chemical reagents to react with samples, and then use complex optical, chromatographic and other analytical methods to obtain data.

Not only is the process cumbersome, but the equipment itself is complex in structure and bulky in size, making it difficult to deploy in real time at the drainage site. In addition, the analysis process requires strict control of environmental conditions, and it takes a long time from sample collection to obtaining results. It is unable to promptly reflect the dynamic changes in fatty acid content in the drainage system. In the face of sudden changes in water quality or pollution accidents, traditional equipment cannot respond quickly and it is difficult to provide accurate data in a timely manner.

[0026] A three-way solenoid valve 46 is fixedly installed at the bottom of the lower half of the first rotary joint 45, and the three-way solenoid valve 46 is located below the external box 1. A rotating cylinder 42 is fixedly installed on the top of the separation cylinder 41, and the rotating cylinder 42 is rotatably connected to the inside of the top wall of the external box 1. The cleaning component 5 includes an internal cylinder 53, and a connecting rod 55 is fixedly installed on the outside of the internal cylinder 53. A scraper rod 56 is fixedly installed on the outside of the connecting rod 55, and the scraper rod 56 is attached to the inner wall of the hydrophilic microporous membrane 47. The power component 2 includes a first bevel gear 21 and a second bevel gear 22.

[0027] In this embodiment, when the fatty acid content is measured online, first, a sample is taken from the inside of the sewage pipe through a pipeline. After sampling, impurities in the sewage are filtered through a filtering system. The filtered sewage is input into the separation cylinder 41 and the conical cylinder 43 through the water inlet pipe 6 and the connecting port 7. At this time, the power bevel gear 23 is driven to rotate by the starting motor 24. The rotation of the power bevel gear 23 drives the first bevel gear 21 below to rotate.

The connecting pipe 32 connects the storage box 31 with the inside of the external box 1. A drain pipe 33 is fixedly installed on the outside of the storage box 31. The drain pipe 33 is connected with the inside of the storage box 31. A second rotary joint 57 is fixedly installed on the top of the internal cylinder 53. The second rotary joint 57 is divided into two sections, the upper and lower sections, and the two sections are rotatably connected. The lower half of the second rotary joint 57 is fixedly installed on the top of the internal cylinder 53. A bracket 58 is fixedly installed on the top of the external box 1. The bracket 58 is fixedly connected to the upper half of the second rotary joint 57. A water pump 52 is fixedly installed on the top of the storage box 31. The water inlet of the water pump 52 is located inside the storage box 31. A circulating water pipe 51 is fixedly installed between the water outlet of the water pump 52 and the second rotary joint 57. A one-way nozzle 54 is fixedly installed on the outer side of the inner tube 53 , and the one-way nozzle 54 connects the inside of the inner tube 53 with the outside. The connection direction of the one-way nozzle 54 is from the inside of the inner tube 53 to the outside.

[0030] In this embodiment, when oil and water are separated, the separated water enters the interior of the external box 1 and then enters the interior of the storage box 31 through the connecting pipe 32. After entering, the water is stored in the storage box 31. When the water level in the storage box 31 is higher than a certain height, the excess water will be discharged through the drain pipe 33. The discharged water can be discharged into the sewer again. A part of the separated water will be retained in the storage box 31. At this time, the internal water is passed into the interior of the internal cylinder 53 through the circulating water pipe 51 and the second rotary joint 57 by starting the water pump 52, and is sprayed out through the external one-way nozzle 54 and cooperates with the rotation of the internal cylinder 53.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] Working principle: First, a sample is taken from the inside of the sewage pipe through a pipeline. The sampled sewage is filtered out of impurities through a filtering system. The filtered sewage is passed through a water inlet pipe 6 and input into the separation cylinder 41 and the conical cylinder 43 through a connecting port 7 at the top of the separation cylinder 41; Start the motor 24, and the power bevel gear 23 at the output end of the motor 24 rotates. Since the power bevel gear 23 and the first bevel gear 21 are meshed with each other, the first bevel gear 21 below is driven to rotate. The first bevel gear 21 is fixedly installed on the top of the rotating cylinder 42, thereby driving the rotating cylinder 42 below to rotate. The rotating cylinder 42 is fixedly connected to the separation cylinder 41, so the separation cylinder 41 and the conical cylinder 43 rotate accordingly. During the rotation process, the centrifugal force generated causes the internal water to be discharged to the inside of the external box 1 through the hydrophilic microporous membrane 47 on the inner wall of the separation cylinder 41 and the conical cylinder 43, while the grease in the sewage is retained inside by the hydrophilic microporous membrane 47, thereby achieving the effect of separating the oil and water in the sewage. The separated grease is discharged through the outlet on the right side by opening the three-way solenoid valve 46, and the discharged grease is transported to the inside of the detection mechanism for detection; After the oil and water are separated, the electric slide rail 25 is started, and the track slider on the outer side of the electric slide rail 25 drives the motor 24 to move upward, so that the power bevel gear 23 moves upward and fits with the second bevel gear 22 above. The rotation of the motor 24 drives the second bevel gear 22 to rotate. The second bevel gear 22 is fixedly installed on the top of the inner cylinder 53, so it drives the inner cylinder 53 below to rotate. A connecting rod 55 is fixedly installed on the outer side of the inner cylinder 53. A scraper rod 56 is fixedly installed on the outer side of the connecting rod 55. The scraper rod 56 fits the inner wall of the hydrophilic microporous membrane 47. As the inner cylinder 53 rotates, the scraper rod 56 scrapes the inner wall of the hydrophilic microporous membrane 47 to scrape off the grease remaining on the inner wall of the hydrophilic microporous membrane 47, and the grease is discharged again through the three-way solenoid valve 46 after scraping. During oil-water separation, the separated water enters the outer box 1 and then enters the storage box 31 through the connecting pipe 32 for storage. When the water level in the storage box 31 is higher than a certain height, the excess water will be discharged through the drain pipe 33. A portion of the separated water will be retained in the storage box 31. At this time, the water pump 52 is started. The water pump 52 passes the water in the storage box 31 through the circulating water pipe 51 and into the inner tube 53 through the second rotary joint 57. A one-way nozzle 54 is fixedly installed on the outer side of the inner tube 53. Water is sprayed out through the one-way nozzle 54. At the same time, the inner tube 53 rotates to spray water outward and rinse the internal hydrophilic microporous membrane 47. The cleaned water is discharged through the outlet on the left by opening the three-way solenoid valve 46.
