Abstract

The invention discloses a sludge concentration online measurement method and device, electronic equipment and a medium. The method comprises the following steps: determining initial waveform information of a microwave signal; enabling the microwave signal to penetrate through a test sludge sample to obtain test waveform information; obtaining measurement data according to the initial waveform information and the test waveform information; establishing a fitting relationship between the measurement data and the concentration of the test sludge sample; enabling the microwave signal to penetrate through a to-be-detected sludge sample, and calculating the concentration of the to-be-detected sludge sample according to the fitting relationship. The sludge concentration test is carried out based on the microwave propagation principle, and the test result ensures the test precision.

Description

technical field [0001] The invention relates to the field of sludge concentration measurement, and more specifically, to an online measurement method, device, electronic equipment and medium of sludge concentration. Background technique [0002] Sludge concentration, which is the milligrams of net weight of dry sludge suspended and mixed per unit volume in the aeration zone in the activated sludge process, is an important parameter of the MBR system, which not only affects the removal capacity of organic matter, but also affects the membrane flux. Therefore, online detection of sewage concentration is of great significance in the process of sewage treatment. [0003] For many years, the determination of sludge concentration is usually by using the more traditional weighing method, that is, the sludge concentration is calculated by comparing the weight of the dried sludge with the original weight of the sludge. This method is time-consuming and inefficient, and cannot meet t...
