การเลือกพื้นที่ฝังกลบขยะและการเตรียมการใช้งานหลังการฝังกลบ กรณีศึกษา : เทศบาลเมืองฉะเชิงเทรา / ศมลวรรณ วรกาญจน์ = Sanitary landfill site selection and preparation for post used, case study : Chacheangsao Municipality / Samonwan Worrakan
The objectives of this research are to determine criteria for sanitary landfill site selection; identify factors that should be considered in finding potential for post used; and to propose appropriate site to construct sanitary landfill for Chacheongsao Municipality. This study finds 8 criteria for sanitary landfill site selection consisting of (1) the distance should be approximately 10-15 km. from source of garbage; (2) the area should be situated less than 7.5 km. from main road; (3) the slope should not more than 3%; (4) the soil should have poor drainage capacity; (5) the distance from surface water should be at least 1,000 m.; (6) the underground water is deeper than 20 m.; (7) the location should be further from medium density community at least 2,000 m.; and (8) the existing land use should be old mining site, abandon pond or field; and undeveloped lands. Then, the diagram models to run the Arc/GIS was formulated, and the amount of future’s garbage was estimated in order to figure out the appropriated land size for sanitary landfill.
From case studies, this research finds 3 types of sanitary landfill post used which are park, botanical garden, and sport facility. The type of post used was considered according to 6 factors, which are the surrounding land use, direction of city growth, population density, accessibility, visual quality, and type of public area that needed.
Result from the analysis shows that an appropriate site is 776 rai, situated in Khon Hin Sorn, Phanom Sarakham, which is 60 km. away from Chacheongsao Municipality. The recommended post used is a botanical garden that can be used for research and recreation. Models created in this study can be applied to perform sanitary landfill site selection in any area, which will minimize an environmental impact while benefit to community. The factors identifying potential of post used can also be applied to any sanitary landfill site, which can make people aware of other benefit of the site.
