| dc.description.abstract | To confront the requirement of the sustainable development of human beings and the sustainable use of water resource, it becomes the imperious current that can improve the stability, efficiency and effectiveness of wastewater treatment through the automation and optimization of wastewater treatment systems. For this reason, it is important to research and develop various kinds of technology and equipment of an automatic real-time water quality and water quantity monitoring system. Respecting the deficiencies of the traditional measurement equipments and experiment analysis that can not offer the necessary information immediately and completely when the control strategy of wastewater treatment has to be made or the situation of unusual water quality has happened, the development of an automatic water quality and quantity monitoring system with the optics method that have fast quantity examine, cost low construction, etc., is efficacious to solve and improve the problem caused by the traditional method.
This research is mainly to utilizes spectrum analysis and digital image analysis to develop an automatic real-time water quality and quantity monitoring system which can apply to experiments and wastewater treatment. There are two parts to develop to this research, one is the multiple components algorithm for a qualitative and quantitative analysis method of COD and SS, and the anther is the trigonometric function method and the regression model method for flow and water level. The results indicate that the stability and the accuracy of the monitoring system is superior to the experiment analysis for water quality measurement, and each of the relative percent difference of COD and SS between the monitoring system and the experiment analysis in many place of wastewater treatment is mostly less than 20% and 15%. Moreover, the relative percent difference of flow between the monitoring system and pilot system is less than 2%.
Altogether, Utilizing spectrum analysis and digital image analysis to develop an automatic real-time water quality and quantity monitoring system for COD, SS and flow is stable and accurate respectably. It can not only offer real-time information for wastewater treatment, but also announces the operators that the water quality is unusual in order to improve the efficiency and effectiveness of wastewater treatment. | en_US |
