Application of MATLAB Image Processing Technology in Sewage Monitoring System
[attachment=36449]
Sewage Treatment
Sewage treatment is the process of removing contaminants from wastewater and household sewage.
It includes processes to remove physical, chemical and biological contaminants.
Its objective is to produce an environmentally safe fluid waste stream and a solid waste suitable for disposal or reuse (usually as farm fertilizer).
The size and number of bubbles nucleated in a water body depends on the history of the water body and type of suspended particles.
Image Processing
Image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image.
MATLAB in Image Processing
Image Processing Toolbox provides a comprehensive set of reference-standard algorithms and graphical tools for image processing, analysis, visualization and algorithm development.
Objective
This paper puts forward the application of MATLAB image processing technology in sewage monitoring system.
The percentage of the bubbles on the surface of the water is got by functions in the image processing toolbox of MATLAB.
The automatic alarm will be raised when the percentage of the bubbles exceeds the setting value.
IMAGE BINARYZATION
Threshold method is a simple and effective method for image segmentation.
Threshold is a value used to distinguish the pixel of the object and the background.
If the gradation of pixel is greater than or equal to threshold, the pixel belongs to the object; otherwise it belongs to background.
im2bw(Image, level) - “Image” is the input image and level is the threshold.
Conclusion
This sewage monitoring system gets the percentage of the bubbles after a series of processes that determine whether the amount of sewage exceeds the standard or not.
The device restricts the sewage emission of the factories in an scientific and effective method.
Thus it provides an accurate and fair way for enviromental administration.
