چکیده مقاله :
به منظور تعیین مکان مناسب برای خاکچال، ابتدا با گردآوری نیازمندی های کاربری زمین به عنوان خاکچال از منابع مختلف، جدولی برای تعیین درجه تناسب زمین ها به منظور استفاده برای محل دفن بهداشتی پسماندها با استفاده از چارچوب فائو طراحی شد، سپس به‎طور موردی داده های مربوط به کیفیت زمینِ فعلی خاکچال تبریز جمع آوری و در جدول مذکور قرار داده شد و در نهایت درجه تناسب آن مشخص گردید. پس از شناسایی کیفیت های زمین مورد استفاده به عنوان خاکچال پسماندهای شهر تبریز و تطبیق این موارد با معیارهای لازم برای بهداشتی بودن خاکچال موجود در جدول مذکور، درجه تناسب محل فعلی دفن پسماندهای شهر تبریز با محدودیت زیاد یا تناسب کم (S3) تعیین شد و پیشنهاداتی به منظور جلوگیری هر چه بیشتر آلودگی منابع آب های سطحی و زیرزمینی که مورد استفاده برای آبیاری در بخش کشاورزی می باشنـد داده شـد. از آن جملـه می توان به استفاده از لایه های نفوذناپذیر مانند ژیوممبران و ژیوتکستایل، ایجـاد سیستـم زهکشـی برای جمع آوری شیرابه تولیدشده و پمپاژ آن به خارج از محل دفن، استفاده از حوضچه‎های تبخیری، تفکیک نوع پسماند از نظر بیمارستانی و غیربیمارستانی بودن، جداسازی زباله های تر از خشک در مبدا و غیره اشاره نمود.
In this order to localization of sanitary landfills, the requirements of applying the studied site as a landfill were collected, and a table was designed according to FAO for determining the degree of land suitability for using as the sanitary landfill. The data related to the quality of Tabriz’s landfill site were collected and after fitting them to the mentioned table, the degree of its suitability was specified. Based on the results of quality recognition of the utilized site as the landfill of Tabriz, and its comparison with the necessary criteria for being sanitary (table 1), the suitability degree of the landfill of Tabriz was determined as S3 representing low suitability of the used site as Tabriz’s landfill. In conclution, the suggestions for preven surface and subterranean water resources pollution used for irrigation in agriculture using impermeable layers like geomembrane and geotextile, making drainage system to collect the produced latex, and pumping it out of the landfill, using of evaporation ponds, separation hospitable and inhospitable wastes, separation of dry waste from wet waste in the source were recommended.
