Embodiment Construction

[0027] The operation of the device is divided into the following stages.

[0028] The first stage (water intake stage): In order to monitor the settlement performance of the mixed liquid at the outlet of the aeration tank in real time, a hole is artificially drilled at the outlet of the aeration tank, and the hose drainage is connected with the integrated real-time monitoring and analysis device for sludge settlement. , The water outlet solenoid valve realizes timing control, and the water inlet and outlet solenoid valves are controlled by the industrial computer. After the water inlet solenoid valve is opened, the mixed liquid at the outlet of the aeration tank is poured into the 1000mL measuring cylinder under the action of the water inlet peristaltic pump, and the end of the water inlet pipe is fixed to the middle of the measuring cylinder to ensure that the mixed liquid can be fully filled in the measuring cylinder. mix.

[0029]The measuring cylinder is located in the sl...

Abstract

The invention discloses an integrated sludge sedimentation real-time monitoring and analyzing device and method, and belongs to the field of activated sludge process aeration tank operation. A water inlet pump, a water outlet pump, an aeration tank outlet mixed liquid collection device, an image acquisition device and image analysis equipment are integrated in a closed lightproof cabinet and are fixed near an aeration tank outlet. According to the invention, sludge sedimentation monitoring and computer vision are combined, sampling is carried out at intervals, the real-time sludge sedimentation process characteristic rule instead of the sludge sedimentation ratio is obtained at regular time, and the process is analyzed and monitored through an automatic monitoring analysis system. The device is closed, a constant light source is adopted in the device, interference of an external light source is eliminated, and accurate and exclusive measurement of the sludge sedimentation process is achieved. A camera in the device adopts an infrared and visible light binocular camera, and information such as chromaticity, brightness and color gradation of a sedimentation image is extracted, recognized and analyzed, so that multiple characteristics such as sludge sedimentation speed, sedimentation proportion and supernate chromaticity are obtained to reflect the sedimentation performance of activated sludge.

Description

technical field [0001] The invention relates to an integrated sludge settlement real-time monitoring and analysis device and method, belonging to the field of activated sludge process aeration tank operation. Background technique [0002] With the rapid development of urbanization and the intensification of environmental pollution, urban water environment problems are becoming more and more serious, and the ecological security of urban water systems is facing severe challenges. The urban sewage treatment plant is not only the core unit of the urban water cycle, but also an important node and difficult point of water environment monitoring. The sewage treatment plant collects the sewage and discharges it into the environment after reaching the standard, thus greatly reducing the impact of pollutants on the environment. At this stage, the construction of new sewage plants is basically completed, and the operation and maintenance of sewage plants need to be optimized, includin...
