| Summary: | 碩士 === 淡江大學 === 水資源及環境工程學系 === 86 === Abstract：Incineration is the first priority, landfill,
however, the secondary one in the waste treatment policy.
Nevertheless, the ash generated from the incineration process
requires further disposal. Therefore, landfill is still the
final solution for solving the waste treatment problems .Owing
to the residents* protest caused by the "NIMBY" syndrome, a
landfill site is difficult to llocate. In order to prolong the
life span of a landfill, the implementation of waste reduction
and recycling program, to some extenVia interview, data
collection and statistics, this study investigates the common
defects occurred in the three stages of the landfill, and
examines if the common defects being improved or corrected
during different stages. This study also considers the cause of
the defects, and suggests proper solutions to avoid the
deterioration of the construction quality and secondary
pollution. Above all, this study will serve as a management
guideline for construction, maintenance and closure of a general
waste/ash laResults show that in the construction stage, the
improper monitoring of the site preparation and main
construction results in the deterioration of the construction
quality. Besides, the poor site safety management caused the
poor environment sanitation. In the second stage, improper
operation and maintenance of the pollution control facilities,
high volume industrial waste in the landfill, lacking of
environmental monitoring system and poor employee training
originate the odor, waste water overflow, methaneAll the defects
shown in this study reveals high duplication with the former
studies. It shows that there are no proper control of these
problem, in spite of the awareness. It is important that a
management and control strategy of the construction, operation,
maintenance and closure of the landfill should be built up. In
addition, a tracking and following up system should be
implemented for the improper managed landfills.
