[0024] The end of the first connecting pipe 8 extends to the top of the sludge sampling bucket 3. A fifth valve 29 is arranged on the first connecting pipe 8. A first spray head 9 is installed at the end of the first connecting pipe 8. The other end of the first water pump 7 is communicated with a second connecting pipe 10. The end of the second connecting pipe 10 extends to the upper part of the sludge activity sampling tank 5. A second spray head 11 is installed at the end of the second connecting pipe 10. A first valve 12 is installed on the second connecting pipe 10. The top of the first water pump 7 is communicated with an external water supply pipe 30. A clean water storage bin 31 is arranged at the top of the bottom mounting table 1. The end of the external water supply pipe 30 extends into the clean water storage bin 31. A second water pump 13 is arranged below the first water pump 7. The input end of the second water pump 13 is communicated with a water extraction pipe 14. The end of the water extraction pipe 14 is connected and communicated with the bottom of the sludge sampling bucket 3. The output end of the second water pump 13 is communicated with a sludge water supply pipe 15.

[0025] The end of the sludge water supply pipe 15 is connected and communicated with the sludge activity sampling tank 5. A second valve 16 is arranged on the sludge water supply pipe 15. An air pump 17 is arranged above the second water pump 13. One end of the air pump 17 is communicated with a first air pipe 18. The end of the first air pipe 18 extends into the sludge sampling bucket 3. The other end of the air pump 17 is communicated with a second air pipe 19. The end of the second air pipe 19 extends into the sludge activity sampling tank 5. A first drain pipe 20 is connected and communicated with the bottom side of the sludge sampling bucket 3. A third valve 21 is arranged on the first drain pipe 20.

[0026] Two outer wall connecting plates 22 are symmetrically arranged on the outside of the sludge activity sampling tank 5. A number of opposed fiber optic sensors 23 are evenly arranged on the outer wall connecting plates 22. The ends of the opposed fiber optic sensors 23 all extend into the sludge activity sampling tank 5. A control display panel 24 is arranged on the side of the outer wall connecting plate 22. A number of opposed fiber optic sensors 23 are connected by a data connection line 25 arranged therebetween. The data connection line 25 is connected with the control display panel 24. A second drain pipe 26 is connected and communicated with the bottom side of the sludge activity sampling tank 5. A fourth valve 27 is arranged on the second drain pipe 26. A push handle 28 is arranged on the side of the bottom mounting table 1.

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the sludge sampling bucket 3 and the sludge activity sampling tank 5 are both made of transparent materials.

[0028] This makes it more convenient for users to observe the activated sludge entering the sludge sampling bucket 3 and the sludge activity sampling tank 5.

[0029] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the first water pump 7, the air pump 17 and the second water pump 13 are all fixedly connected to the connecting support plate 6 through the provided connecting plates.

[0030] This makes the first water pump 7, the air pump 17 and the second water pump 13 operate more stably.

[0031] Embodiment 4: The difference between this embodiment and Embodiment 1 is that anti-slip patterns are provided at the end of the push handle 28.

[0032] This greatly increases the friction on the surface of the push handle 28, which is beneficial for users to push the bottom mounting table 1.

[0033] In this embodiment, since most of the existing detection of the sedimentation performance of activated sludge still uses the traditional method of visual inspection with a graduated cylinder, the method for measuring the sedimentation performance of activated sludge is time-consuming, and the detection accuracy is relatively poor. It cannot provide immediate and effective feedback for the sewage treatment plant, thus making it inconvenient for the sewage treatment plant to adjust the treatment process in a timely manner.

[0034] In summary, during specific implementation, when a user needs to detect the sedimentation performance of the activated sludge in a sewage treatment plant, the user first needs to put the activated sludge into the sludge sampling bucket 3. By starting the first water pump 7, the clear water stored in the clear water storage bin 31 is pumped through the external water supply pipe 30. By opening the fifth valve 29, it is injected into the sludge sampling bucket 3 through the first connecting pipe 8. Then, the stirrer 4 at the bottom of the sludge sampling bucket 3 is started to make the activated sludge put into the sludge sampling bucket 3 evenly mixed with the clear water. During the mixing process, the user can also start the air pump 17, so that the air pump 17 blows air into the mixed liquid in the sludge sampling bucket 3 through the first air pipe 18, thereby improving the mixing effect of the sludge and the clear water.

[0035] Then, by starting the second water pump 13, the second water pump 13 extracts the mixed activated sludge water in the sludge sampling bucket 3 through the water suction pipe 14 and pumps it into the sludge activity sampling tank 5 through the sludge water delivery pipe 15. A number of opposed fiber optic sensors 23 are symmetrically arranged on both sides of the inner wall of the sludge activity sampling tank 5. The activated sludge entering the sludge activity sampling tank 5 begins to settle under natural conditions. During the natural sedimentation process of the sludge, the number of opposed fiber optic sensors 23 can record the downward settling rate and time of the sludge sedimentation, and then transmit the data to the control display panel 24 through the data connection line 25. The user can then detect and record the sedimentation performance of the activated sludge through the control display panel 24 and display the sedimentation parameters of the activated sludge for the operator's reference.

[0036] Moreover, the device is arranged on the bottom mounting table 1, and moving rollers 2 are installed around the bottom mounting table 1, which can facilitate the movement of the device during use and improve the flexible use of the device.
