  • The outbreak of foot and mouth disease in November 2010 raised many social, economic and environmental issues and water contaminations by leachate from carcass disposal sites particularly emerged as a serious concern. In oder to efficiently handle these problems, a critical method is required to transport leachate to livestock manure and sewage treatment plants and purify it. This study aims to present the best applicable method to transport leachate from carcass disposal sites into livestock manure and sewage treatment facilities. We investigated the biological and chemical characteristics such as BOD, COD, SS, TN, TP and Total coliforms. Current conjugated treatments in livestock manure and sewage treatment plants was studied by surveying the operations of those facilities. The NIER-MASS(National Institute of Environmental Research - Mass Balance Evaluation System of Sewage Treatment Facilities) program was applied to present the best conjugated treatment method through estimating the maximum daily load to meet the water quality standards in effluent.

  • This study summarized the case study of a course development of introductory engineering design considering the characteristics of civil and environmental engineering. The course mainly depends on conducting the design projects. The self-developed text book for the course consists of learning and activities of the core elements for the creation and decision of ideas and two independent design projects. Especially, the design project drew from a survey of students majoring in civil and environmental engineering and is well knitted to help students obtain the potential for soft-landing at higher major courses.
