博士 / 國立中央大學 / 環境工程研究所 / 94 / The optimal design of new sewer systems becomes an important issue for the necessary of cost-effectiveness analysis. However the result of traditional design approach is only a very small number of the alternatives can be evaluated; therefore the final design is sometimes deficient and there is no guarantee that it is the best design. This has more inspired the research on computerized optimization models for sewer systems planning and design. In this study, accordin...

碩士 / 國立中央大學 / 環境工程研究所碩士在職專班 / 94 / Abstract People pay more attentions to their living environments as the living standards arise. So far, in Taiwan, the domestic wastewater is only roughly treated by a septic tank before discharged into sewage drains, which causes hygiene problems and deteriorates the living quality. Discharges of improperly treated wastewater also contaminate the rivers and further influence the drinking water quality. Therefore, the sewage system and the wastewater treatme...
