Embodiment Construction

[0048] The following is a detailed description of specific embodiments of the present invention:

[0049] Step 1: Configure an online computer image analysis device for activated sludge, such as figure 1, mainly consists of a sample diluter 1, a peristaltic pump 2, a computer 3, a high-speed camera 4, a microscope 5 and a sample chamber 6. The function of the sample diluter is to dilute the concentration of the original sample to prevent the sample concentration from being too high and block the sample chamber installed under the microscope. In addition, it can also reduce the overlap of floc particles in the sample and cause measurement errors. The sample dilution factor is 1:9. The activated sludge sample and indoor tap water enter the sample diluter according to the flow ratio of 1:9; after the sample is diluted, it is transferred to the sample chamber by a peristaltic pump, and is recycled to the sample diluter as waste liquid discharge; the sample chamber is placed under ...

Abstract

The invention relates to an active sludge online computer image analysis and early warning system and an active sludge online computer image analysis and early warning method thereof. The system consists of a sample diluter, a peristaltic pump, a computer, a high-speed camera, a microscope and a sample chamber. The method comprises the steps of acquiring a morphological image of a sample firstly and then processing the acquired image; analyzing floc size distribution and filamentous bacterium length distribution; associating the floc particle size distribution and filamentous bacterium length distribution of active sludge with settling properties of the active sludge so as to perform early warning on the settling effect of the active sludge.

Description

technical field [0001] The invention belongs to a sewage treatment process detection technology, specifically for the continuous computer graphic analysis of the activated sludge filamentous bacteria in the secondary sedimentation tank (secondary sedimentation tank) in the sewage biological treatment process, so as to detect the possible occurrence A method for early warning of sludge filamentous bacteria expansion. Background technique [0002] Activated sludge process is the most common domestic sewage treatment technology. 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, and the expansion of sludge filamentous bacteria is an important factor affecting the settling performance of activated sludge. According to the skeleton theory of sludge floc formation, filamentous bacteria can p...
