The invention discloses a method and system for detecting a sludge settlement ratio based on image processing. The method comprises: regularly taking sludge out and putting the sludge into a measuring cylinder, and after the sludge is allowed to stand for preset duration, collecting image information of the measuring cylinder equipped with the sludge; performing image processing of the image information; analyzing the image information, and comparing a sludge position with a position where the middle line of the measuring cylinder is to judge whether the sludge position is normal; if the sludge position is normal, calculating the ratio of a sludge area to a total volume of sampling and a ratio of a sludge-water mixing area to the total volume of sampling to obtain the sludge settlement ratio; comparing the sludge settlement ratio with a preset normal range, and if the sludge settlement ratio is in the preset normal range, determining that sludge settlement performance is excellent; and sending settlement data of the measuring cylinder to a cloud platform for statistic analysis. During measurement of the sludge settlement ratio, on-line recording, real-time analysis, and year-on-year / month-on-month analysis are analyzed; abnormity of sludge settlement can be discovered on time; and stability of operation of an active sludge method is improved.
Description
technical field [0001] The invention relates to the technical field of sludge detection, in particular to a method and system for detecting sludge sedimentation ratio based on image processing. Background technique [0002] At present, the country pays more and more attention to environmental protection, and the number of sewage treatment plants increases year by year, and the activated sludge method accounts for the majority of sewage treatment plants. The activated sludge passes through the secondary settling tank to realize the separation of mud and water, and obtain clearer effluent. The quality of activated sludge settling performance is the key to obtain better effluent water quality. Sludge sedimentation ratio (SV) refers to the volume ratio of the settled sludge to the mixed solution taken after pouring the mixed liquid of the activated sludge in the aeration tank into a 1000mL measuring cylinder to the full scale and standing for a certain period of time ( %), whi...
