Detailed Implementation

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0031] Example 1

[0032] A specific embodiment of this utility model discloses an activated sludge performance testing and diagnostic device, such as... Figures 1-2 As shown, the device includes a cabinet 1, a touch screen 2 installed inside the cabinet 1, a pump unit 3, a sensor 4, a measuring cylinder unit 5, a control unit 6 for operating the activated sludge performance testing and diagnostic device, and an information acquisition unit 7. The touch screen 2 is used to realize human-computer interaction and display the performance parameter information of the activated sludge. The pump unit 3 is used to extract sludge from the biological treatment tank and pump it into the measuring cylinder unit 5. The sensor 4 and the information acquisition unit 7 are used to collect and analyze the performance information of the sludge sample in the measuring cylinder unit 5 and feed it back to the touch screen 2.

[0033] Furthermore, such as Figure 2As shown, the measuring cylinder unit 5 includes a measuring cylinder 51, an overflow pipe 52, and a sample inlet pipe 53. The sample inlet pipe 53 connects the pump unit 3 to the measuring cylinder 51, so that the sludge is pumped into the measuring cylinder 51 through the sample inlet pipe 53. One end of the overflow pipe 52 is connected to the measuring cylinder 51, and the other end is connected to the biological treatment tank, so that excess sludge is discharged back into the biological treatment tank through the overflow pipe 52.

[0034] In some embodiments, the overflow pipe 52 is positioned at the 1000 ml position of the measuring cylinder 51 to quantitatively sample the sludge.

[0035] Preferably, the measuring cylinder 51 is detachably connected to the overflow pipe 52 and the sample inlet pipe 53, and the measuring cylinder 51 is detachably installed in the cabinet 1, thereby facilitating the disassembly and cleaning of the measuring cylinder 51.

[0036] Preferably, such as Figure 1 As shown, cabinet 1 is provided with cabinet door 11, which is connected to cabinet 1 by hinges. Cabinet door 11 is used to protect the circuit structure inside cabinet 1.

[0037] Preferably, the cabinet 1 is also equipped with casters 12 to facilitate the movement of the activated sludge performance testing and diagnostic device.

[0038] like Figure 3 As shown, the cabinet 1 is also equipped with an electrical component 13, which includes a power connector 131, a switch 132, and a network port 133. The power connector 131, the switch 132, and the network port 133 are all existing technologies and are used to provide power to the activated sludge performance testing and diagnostic device and to transmit signals. The switch 132 is used to control the switching of the activated sludge performance testing and diagnostic device, which will not be described in detail here.

[0039] In some implementations, control unit 6 may include a PCL controller, such as a Siemens CPU-SR20.

[0040] In some implementations, sensor 4 may be an MLSS sensor (mixed liquor sludge concentration sensor) for measuring the mixed liquor sludge concentration.

[0041] In some implementations, the information acquisition unit 7 includes an edge computing algorithm box and a camera. The edge computing algorithm box, the camera, and the touch screen 2 are connected via a data cable, Wi-Fi, or Bluetooth. The camera is used to take pictures of the sludge settling in the measuring cylinder 51 within a specified settling time, and the edge computing algorithm box calculates the sludge settling ratio in the measuring cylinder 51 in real time. The results are then displayed on the touch screen 2, showing the sludge settling data captured by the camera and the sludge settling ratio calculated by the edge computing algorithm box. Therefore, according to the formula:

[0042] Sludge volume index = sludge settling ratio / mixed liquor sludge concentration;

[0043] The sludge volume index is obtained by measuring the mixed liquor sludge concentration data by sensor 4 and the sludge settling ratio data calculated by the edge computing algorithm box, and the performance of activated sludge in measuring cylinder 51 is detected and diagnosed.

[0044] For example, the model of the edge computing algorithm box can be the SV30 real-time online intelligent detector. Edge computing algorithm boxes are existing technology and will not be described in detail here.

[0045] This invention relates to an activated sludge performance testing and diagnostic device. By incorporating a pump unit 3, a sensor 4, a control unit 6, and an information acquisition unit 7, it enables automatic sampling of sludge and automatic testing and diagnostic of activated sludge performance. This reduces labor costs, minimizes human error, and improves testing accuracy. The cabinet door 11 and casters 12 effectively protect the circuitry within the cabinet and facilitate the movement of the activated sludge performance testing and diagnostic device.

[0047] A specific embodiment of this utility model discloses an activated sludge performance testing and diagnostic device, such as... Figure 4 As shown, the difference from Embodiment 1 is that it also includes a water production unit 8 installed in the cabinet 1.

The control unit 6 can control the water production pump 81 to pump water from the external water source into the water tank 82 after filtration through the permeable membrane, thereby completing the pre-production and storage of cleaning water for the measuring cylinder unit 5.

[0049] For example, the permeable membrane can be a columnar membrane.

[0050] Furthermore, the pump unit 3 includes a sampling pump 31 for pumping sludge into the measuring cylinder unit 5, a backwash pump 32 for pumping water from the water tank 82 to the measuring cylinder unit 5 for cleaning, and a sludge discharge pump 33 for discharging sludge from the measuring cylinder unit 5. The pump unit 3 can provide power for the cleaning and sludge discharge of the measuring cylinder unit 5.

[0051] Preferably, the pump unit 3 further includes a booster pump 34, which is used to regulate the pumping pressure within the measuring cylinder unit 5, thereby improving the stability and adjustability of cleaning and draining the measuring cylinder unit 5. The booster pump 34 is prior art and will not be described in detail here.

[0053] Example 3

[0054] A specific embodiment of this utility model discloses an activated sludge performance testing and diagnostic device, such as... Figure 5 As shown, the difference from Embodiment 1 or Embodiment 2 is that it also includes a constant temperature control unit 9, which is used to regulate the temperature inside the cabinet 1, thereby ensuring that the activated sludge performance testing and diagnostic device can operate normally in low-temperature environments such as winter.

[0055] In some embodiments, the temperature control unit 9 includes a temperature controller 91 and a heater 92. The temperature controller 91 senses the ambient temperature and regulates the temperature inside the cabinet 1 by controlling the heater 92. For example, the temperature controller 91 can be a Chint cabinet temperature controller NTK1. The temperature controller 91 and the heater 92 are prior art and will not be described further here.

[0056] The activated sludge performance testing and diagnostic device of this invention can regulate the temperature inside the cabinet 1 by setting a constant temperature control unit 9, so as to ensure that the activated sludge performance testing and diagnostic device can operate normally in low-temperature environments such as winter.
