specific Embodiment approach 1

[0023] Specific implementation mode one: as figure 1 As shown, this embodiment performs real-time detection of the fractal pulsation image of the floc in water according to the following steps:

[0024] (1) Install an intelligent machine vision sensor near the front section of the reaction tank of the water plant;

[0025] (2) Take the flocculation water samples at 2 to 5 minutes away from the water flow time at the inlet of the reaction tank for continuous shooting, and illuminate them with LED light sources to improve the clarity of the flocculation images;

[0026] (3) Set the intelligent machine vision sensor to shoot at a speed of 1 to 5 frames per second and transmit the collected digital grayscale flocculation images to the host control device through the digital communication interface;

[0027] (4) Compile the three flocculation image files collected continuously into a queue (numbered 1, 2, 3) in chronological order, the length of the queue is fixed at 3, and a new ...

specific Embodiment approach 2

[0047] Specific embodiment two: the difference between this embodiment and specific embodiment one is that step (3): set the intelligent machine vision sensor to shoot at a speed of 1 frame / second and collect the digital grayscale flocculation image through the digital communication interface sent to the upper control device. Other steps are the same as in the first embodiment.

Abstract

This invention relates to a real time test method for typing pulsatile images of flakes in water including: applying an intelligent machine vision sensor to pick up flocculated water samples of the reaction pool front section to arrange the collected flocculation images to a queue in terms of first in first out principle, utilizing the function relation of the flake projection area percentage standard difference Delta S and the flake long shaft percentage standard difference Delta L expressing the pulsatile phenomenon of flakes to compute the current statistic typing dimension value W.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to a water treatment detection method. Background technique [0002] In the production process of water treatment, the degree of perfection of the flocculation process directly affects the treatment effect of subsequent treatment such as sedimentation, filtration and other process units. Due to the complex, fragile and irregular characteristics of the floc structure in water, there has been a lack of suitable methods for the study of the flocculation process. The proposal of fractal theory has filled the blank of flocculation research method. The parameter that characterizes the fractal system is the fractal dimension, which corresponds to the degree of irregularity and complexity of the fractal body or space-filling measure. At present, the determination of the fractal dimension of flocs in water mostly adopts the static image method, that is, the flocs are deposited on a gla...
