To overcome these problems effectively, the development of an automatic water quality 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 study uses CMOS camera and laser diodes, and in accordance with principles of triangulation, Beer-Lambert''s law and the image processing technologies to development a automatic measure techniques. It can be used to simultaneous measure water level or flow rate, concentration of suspended solid of techniques. The system was built and tested on a laboratory-scale batch reactor; this device has a certain Applicability and development potential. Observation of laser beam penetrates light and scattered light intensity through the change of circumstances, according to real test and verification result, the absorbance decreased with the settling time or hydraulic retention time increasing. Base on this information, the process can be simultaneous measure the upper concentration of suspended solid of liquid, and the results showed that the concentration of discharge water to set 25 mg / L and 20 mg / L corresponding to the absorbance values of the red and green light as the control basis, and through manual analysis for comparison, are in compliance with effluent concentration, it enough to support that the measurement device is useful on the feasibility of certain. By the measurement device and technique can determine the quality of upper water is conforming to the standard on time in the future. In order to auto-control the quality of upper water and HRT, to reduce operating costs and improve the effectiveness of sewage treatment systems. Shu-Liang Liaw 廖述良 2011 學位論文 ; thesis 104 zh-TW
