[0023] It should be noted that in the embodiment, the support mechanism is used to provide necessary support and mounting surface for other components of the entire detection device, so as to ensure that the entire detection mechanism can stably perform the detection task; the sedimentation container 1 is used to load and settle the sewage sample, so as to detect the sludge SV30 of the sewage sample by the first detection mechanism or the second detection mechanism 4.The PLC control module is responsible for coordinating the work of all components of the entire detection device. The PLC control module calculates the sludge SV30 of the sewage sample based on the detection data received from the first detection mechanism or the second detection mechanism 4 to achieve the detection of the sludge SV30 of the sewage. The first detection mechanism detects the sludge SV30 of the sewage in the settling container 1 by using an image recognition mode. Specifically, the first detection mechanism includes a first camera 2 and a second camera 3. The first camera 2 is used to collect images of the sewage in the settling container 1 after standing and settling for 30 minutes, and send the detected images to a server loaded with an image recognition model to calculate the sludge SV30 value of the sewage sample in the settling container 1. The server sends the sludge SV30 value to the PLC control module in the form of an analog quantity. The second camera 3 is used to monitor whether the sewage sample in the settling container 1 appears abnormal during the settling process. If abnormality occurs, an abnormal signal is sent to the PLC control module, and the PLC control module sends the abnormal information to the PLC host computer. The PLC host computer displays the information on the display screen or sends a sound signal to prompt the operator to adjust the settling container 1 to ensure the normal progress of the detection task. The second detection mechanism 4 is used to detect the sludge SV30 of the sewage in the settling container 1 by using a mechanical detection mode. Specifically, the second detection mechanism 4 includes a first driving motor 401, a first transmission rod 402, a guide rod 403, a sliding block 404, and an optical fiber sensor 405. Since the specification of the settling container 1 is known, when the settling container 1 is injected with 1000ml of sewage sample, the liquid level height of the sewage sample in the settling container 1 is also a known value, which is denoted as H. Before the sewage sample settles, the sliding block 404 is at the same level as the highest liquid level of the sewage sample. After the sewage sample settles in the settling container 1 for 30 minutes, the PLC control module controls the first driving motor 401 to rotate. The first transmission rod 402 converts the rotary motion of the output shaft of the first driving motor 401 into the motion of the sliding block 404 in the vertical direction along the first transmission rod 402. The sliding block 404 drives the optical fiber sensor 405 to move in the vertical direction. At this time, the optical fiber sensor 405 emits light to the settling container 1 and receives the diffuse reflection light of the settling container 1 to determine the boundary between the clear water and the sludge. Specifically, when the optical fiber sensor 405 encounters the upper clear liquid, the diffuse reflection light is weak. When the optical fiber sensor 405 encounters the bottom sludge, the diffuse reflection light is strong. When the optical fiber sensor 405 encounters a sudden change in the intensity of the diffuse reflection light, i.e., the optical fiber sensor 405 is located at the boundary between the clear water and the sludge. At this time, the first driving motor 401 stops rotating, and the optical fiber sensor 405 stops at the boundary between the clear water and the sludge. The falling height of the sliding block 404 at this time is denoted as h, and the collected data is transmitted to the PLC control module. The PLC control module calculates the sludge SV30 value of the sewage sample in the settling container 1 according to the formula:

[0024] The value of SV30 is calculated; in the implementation of the present application, when the SV30 index of the activated sludge mixture in the aeration tank needs to be detected, first, 1000ml of sewage sample is input into the settling container 1, then the sewage sample is allowed to settle in the settling container 1 for 30 minutes; then the first detection mechanism or the second detection mechanism 4 detects the data of the settled sewage sample and sends the detected data to the PLC control module, finally, the PLC control module calculates the value of the sludge SV30 of the sewage sample according to the received detection data, to realize automatic detection in two modes of image recognition and mechanical detection. Compared with the detection mode in the prior art which relies on manual operation including sampling, standing, observation and reading, the present embodiment can realize automatic detection of sludge SV30, thereby ensuring the efficiency and accuracy of detecting sludge SV30.

[0025] It should be further pointed out that in the present embodiment, the image recognition model is a convolutional neural network image recognition model deployed in a Pytorch environment, when the first camera 2 collects the image of the sewage in the settling container 1 after standing and settling for 30 minutes, the image recognition model takes this image as input and infers the measurement result; in addition, the deployment of the image recognition model belongs to the prior art, and the present embodiment can directly introduce the deployment mode of the image recognition model in the prior art to cooperate with the image collected by the first camera and calculate the value of sludge SV30; as a preferred embodiment, based on the environment of python3.9, pycharm compiler, anaconda management environment and pytorch deep learning framework, by using self-made water plant and sewage plant flocculation degree dataset as sample set, ResNet18 convolutional neural network architecture is manually built, model construction, model training and model testing operations are performed, and finally the feasibility and effectiveness of the model are determined by accuracy.
