The purposes of this study are to learn actual states of the energy aspect on sewage works in Japan and to investigate a selecting/evaluating strategy of possible wastewater treatment alternatives in response to site specification. A feasibility study on constructing a wastewater treatment system is carried out, employing an economic costing function. As a result, an evaluated strategy of a feasible treatment system applicable to site specification is shown by use of an economic costing function of construction and O&M on sewage works in Japan.The next objective of this study is to estimate economic costs of pollution by sewage treatment. In this study, an economic cost estimation of pollution by sewage treatment is defined as "social cost." The social cost of pollution to unit volume of treated wastewater is estimated for several sewage treatment systems. By summing social cost and treatment cost, a synthetic cost is obtained. As a result, it is shown that the relationship between social costs and watewater treatment alternatives can be recognized with ease by use of the estimating method of social cost.The meaning of the construction and maintenance costs of a wastewater treatment system for users and an administrative can be recognized by use of the evaluation method of cost-benefit analysis.

本研究的目的是了解日本污水处理厂的能源方面的实际状况，并调查可能的污水处理替代方案的选择/评估策略，以响应现场规范。采用经济成本函数对建设污水处理系统进行了可行性研究。因此，一个可行的处理系统，适用于现场规格的评价策略是通过使用的经济成本函数的建设和O&M在日本的污水works.The本研究的下一个目标是估计污染的污水处理的经济成本。在这项研究中，污水处理污染的经济成本估计被定义为“社会成本”。“对几个污水处理系统的单位体积经处理的废水的污染的社会成本进行了估计。将社会成本与治理成本相加，得到综合成本。结果表明，社会成本的估算方法可以很容易地认识到社会成本与污水处理方案之间的关系，成本效益分析的评价方法可以认识到污水处理系统的建设和维护成本对用户和管理者的意义。
