چکیده
زمینه و اهداف: شیرابه محل دفن پسماند بهواسطه دارا بودن ترکیبات پیچیده آلی و معدنی، سمی بوده و دارای پتانسیل آلایندگی بالایی است. برآورد شاخص آلودگی شیرابه محل دفن (LPI) در پیشبینی اثرات طولانی مدت شیرابه بر محیطزیست و پیشنهاد راهکارهای مناسب مدیریت و تصفیه آن بسیار حائز اهمیت است. لذا در این مطالعه شاخص آلودگی شیرابه (LPI) محل دفن پسماند شهری سنندج ارزیابی شده است.
مواد و روشها: شش نمونه از حوضچه نگهداری شیرابه در پائین دست محل دفن پسماند شهری سنندج درطول فصل زمستان و بهار جمعآوری شد. آنالیزهای فیزیکو شیمیایی به منظور تعیین مشخصات شیرابه انجام شد. شاخص آلودگی شیرابه بر اساس 18 پارامتر شامل pH، TDS، BOD، COD، TKN، NH4، Fe، Cu، Ni، Zn، Pb، Cr، Hg، As، ترکیبات فنولی، کلراید، سیانید و کل کلیفرم میکروبی محاسبه و ارزیابی گردید. ملاحظات اخلاقی و پژوهشی در تمام مراحل مطالعه در نظر گرفته شد.
یافتهها: نتایج این تحقیق حاکی از بالا بودن pH، COD، BOD، TKN، NH4 در شیرابه محل دفن مورد مطالعه است. همچنین شاخص آلودگی شیرابه بر اساس پارامترهای اندازهگیری شده، 30/19 برآورد شد.
نتیجهگیری: نتایج این مطالعه نشان داد که شاخص آلودگی شیرابه مورد مطالعه نسبت به مقادیر استاندارد LPI برای تخلیه به محیط و آب سطحی به طرز قابل توجهی بالا است. مقدار بالای شاخص LPI نشان میدهد که شیرابه مورد مطالعه خطرناک بوده و دارای پتانسیل آلودگی بالایی میباشد که نیازمند تصفیه پیش از تخلیه به محیط است.
