Problems solved by technology

Previously, the sludge sedimentation ratio was detected manually, but this method has problems such as low efficiency and large errors, and the sludge sedimentation ratio is an item that needs continuous monitoring during the operation of the sewage plant. Continuous manual sampling and monitoring is labor-intensive.
Moreover, manual sampling analysis cannot realize informatization and self-correction through big data analysis
[0003] The image collected by the image acquisition device in the sludge sedimentation ratio detection system in the prior art can only obtain the approximate position of the sludge, which directly leads to a large error in the obtained sludge position

Abstract

The invention discloses a sludge settlement ratio monitoring system and a monitoring method thereof, and relates to the field of sewage treatment. The system comprises a shell, an automatic sampling device, an image acquisition device and a data processing and storage device. The automatic sampling device comprises a measuring cylinder; the image acquisition device comprises a camera, the camera is arranged on the shell, the camera and the measuring cylinder are oppositely arranged, the horizontal plane where a scale corresponding to one half of a sampling volume in the measuring cylinder is located is a first horizontal plane, and the central axis of a camera lens is located in the first horizontal plane; and the data processing and storage device is used for analyzing and calculating theimages acquired by the image acquisition device. According to the arrangement, the camera shoots the form of the water sample in the measuring cylinder more clearly and completely, and the accurate numerical value of the sludge settlement ratio is obtained by analyzing and calculating the shot image. Through the automatic monitoring and control of the monitoring system, the detection is accurateand efficient, and the labor cost is low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sludge sedimentation ratio monitoring system and a monitoring method thereof. Background technique [0002] The activated sludge sedimentation ratio in sewage is a value that needs to be checked frequently. The sludge sedimentation ratio refers to the volume percentage of the sludge after the mixed liquid in the aeration tank settles statically in the measuring cylinder for 30 minutes, which can be used as a reference for the discharge of residual sludge . Previously, the sludge sedimentation ratio was detected manually, but this method has problems such as low efficiency and large errors, and the sludge sedimentation ratio is an item that needs continuous monitoring during the operation of the sewage plant, and continuous manual sampling and monitoring is labor-intensive. Moreover, manual sampling analysis cannot realize informatization and self-correction through bi...
