چکیده مقاله :
زمینه و هدف: یکی از مشکلات خاکچال یا به عبارتی دیگر لندفیلهای قدیمی و رهاشده مساله آلودگی های زیست محیطی جانبی آن است. خاکچال باباحیدر در مجاورت مخزن سد باباحیدر و در سه کیلومتری شهری با همین نام در استان چهارمحال و بختیاری واقع شده است و پسماندهای تولیدی این شهر و برخی از روستاهای اطراف آن به این خاکچال وارد شده و تلنبار میشود. ازآنجاییکه یکی از اهداف اصلی احداث سد تأمین آب شرب منطقه است، لذا وجود این خاکچال می تواند باعث آلوده شدن آب در مخزن سد شده و عملکرد سد را با مشکل مواجه نماید. از این رو در مطالعه حاضر روش های موجود برای مواجهه با این نوع خاکچال ها از لحاظ فنی، اقتصادی و زیست محیطی مورد بررسی قرار گرفت. روش بررسی: به منظور انتخاب بهترین گزینه برای مواجهه با خاکچال مورد مطالعه ابتدا تمام روش های موجود برای مواجهه با خاکچال باباحیدر مورد مطالعه قرار گرفتند و سپس روشهای دارای پتانسیل اجرا شامل پوشاندن خاکچال، حفاری و انتقال به خاکچال جدید، تصفیه با روش خاکشوئی و محصورسازی با اجرای دیوار جداکننده مورد تجزیه و تحلیل قرار گرفتند. یافته ها: نتایج حاصل از انواع معیارهای مقایسه از نظر فنی، اقتصادی و زیستمحیطی نشان داد که شیوه تصفیه با روش خاکشویی از لحاظ پیچیدگی فناوری و نیاز به تجهیزات خاص، راهبری تخصصی، نیاز به آب، مواد مصرفی و شیمیایی، هزینههای سرمایهگذاری و راهبری، شرایط خاصی را میطلبد که اجرایی شدن این روش را با مشکل مواجه میکند. در مقابل روش حفاری و انتقال به خاکچال جدید از لحاظ پارامترهای فوقالذکر بیش ترین قابلیت را برای اجرا دارد. روشهای پوشاندن خاکچال و محصورسازی با اجرای دیوارهای جداکننده از لحاظ شرایط و پیچیدگی های اجرایی مابین دو روش فوق قرار دارند. بحث و نتیجه گیری: با بررسی، مقایسه و امکان سنجی روش های دارای پتانسیل اجرا جهت پاکسازی و احیاء خاکچال مشخص گردید که از میان روش های مختلف احیاء و پاک سازی، روش حفاری و انتقال به خاکچال جدید نسبت به سایر روشها از دیدگاه فنی، اقتصادی و زیست محیطی مناسب تر و دارای قابلیت بیش تری برای اجرا است. از این رو به کارگیری این روش برای خاکچال باباحیدر پیشنهاد می گردد.
Background and Objective: One of the problems in the old landfills in the world is the side environmental pollution. Babaheydar landfill is in the vicinity of the Babaheydar’s dam reservoir and located three kilometers away from the city of the same name in the Chaharmahal and Bakhtiari province and municipal solid waste of Babaheydar city and some surrounding villages is being imported and dumped to this landfill. Since one of the main objectives of Babaheydar’s dam is supplying drinking water and the presence of these landfill can contaminate the dam reservoir water. Therefore, in this study existing methods for facing with this type of landfills was investigating technically, economically and environmentally. Method: In order to select the best option for facing with the landfill, at first, all of the available methods were studied. Then feasible methods such as landfill capping, landfill mining, treatment with soil washing and subsurface cut-off walls were investigated. Findings: Comparison results according to technical, economic and environmental aspects show that soil washing technique in terms of technology and need for special equipment, specialized management, need for water, materials and chemicals, investment and management costs require specific conditions that make the implementation of this method difficult. In opposite, excavation and transfer to a new landfill in terms of above parameters has most potential to execute. The methods of landfill capping and enclosing with subsurface cut-off walls are between two mentioned methods. Discussion and Conclusion: With investigation, feasibility and Comparison of potential executable methods for reclamation and remediation of landfill, it was found that the method of excavation and transfer to a new landfill compared to other methods is more suitable technically, economically and environmentally. Thus, applying of this method is recommended for Babaheydar landfill.
