碩士 === 國立中興大學 === 環境工程學系所 === 103 === Due to the reduction of government manpower, the operation and maintenance of the public sewage treatment plant are mostly outsourced privately, In order to enforce its regulatory monitoring and to ensure the operational quality, Taiwan Construction and Planning Agency, Minister of Interior announced and implemented the “Evaluation Procedures for Public Sewage Treatment Plant “ at April, 18th, 2008, to assist the local governments’ evaluation processes to audit the operation conditions of all wastewater treatment plants. Forty three public sewage systems have been evaluated from 2010 to 2014. This study analyzed the evaluation procedures and the audit results. The unit operation parameters of the evaluated public sewage systems were analyzed. Wastewater treatment facilities units and sludge handling units were also analyzed, such as grit chambers, primary sedimentation tanks, biological treatment units, disinfection units, sludge thickening unit, sludge digestion units, and sludge dewatering units. This study results indicated that the mostly commonly encountered problem by wastewater treatment facility is the insufficiency of influent flow rates and low influent BOD , COD , and SS concentration . A suggestion of the reduction of the designed daily influent rates and BOD concentrations may solve the problem. In addition, to establish a public sewage system contract template and organize training programs to have a better manage the facility and the operators may improve the operation conditions.
