چکیده

فناوری وتلند با استفاده از گیاهان و میکروارگانیسم‏های طبیعی، روشی مؤثر برای حذف آلاینده‏ها از فاضلاب است. در سال‏های اخیر، توجه به فرایندهای تصفیۀ بیولوژیکی برای تصفیۀ فاضلاب در بخش‏های روستایی و کشاورزی، به‏ویژه در کشورهای در حال توسعه، افزایش یافته است. تأسیسات فاضلاب روستایی، نقش مهمی در ارتقای سلامت عمومی و حفاظت از محیط زیست در مناطق روستایی دارد. فناوری وتلند به عنوان روشی مناسب برای تصفیۀ بیولوژیکی فاضلاب در این مناطق مورد توجه قرار گرفته است. تمرکز این مطالعه بر امکان ‏سنجی اجرای وتلند‏ها در روستاهای استان تهران است. مدل‏ها و روش‏های بهره‏برداری از وتلند در سراسر جهان و ایران جمع‏آوری شد و مدل‏های مفهومی بر اساس استانداردهای ایران طراحی شد. لایه‏های داده بر اساس سه معیار کلیدی، عوامل فنی، اجتماعی‌ـ اقتصادی و محیطی طبقه‌بندی شدند. نقشه‏ های مربوطه با استفاده از سیستم اطلاعات جغرافیایی (GIS) توسعه یافتند و روی هم قرار گرفتند. یافته‏ها بیانگر آن است که تقریباً 49 روستا که عمدتاً در نیمۀ غربی استان تهران واقع شده‏اند، بیشترین تناسب را برای احداث وتلند نشان می‏دهند. از میان این روستاها، 12 روستا از سوی ادارۀ آب و فاضلاب روستایی استان تهران برای توسعۀ سیستم‏های تصفیۀ فاضلاب در اولویت قرار دارند که فناوری وتلند به عنوان گزینۀ مطلوب توصیه می‏شود.

چکیده [English]

Wetland technology, utilizing natural plants and microorganisms, is an effective approach for removing contaminants from wastewater. In recent years, there has been increased attention towards biological treatment processes for wastewater treatment in rural and agricultural sectors, particularly in developing countries. Rural wastewater facilities play a crucial role in promoting public health and environmental protection within rural areas. Wetland technology has emerged as a viable method for biological wastewater treatment in these regions. This study focuses on assessing the feasibility of implementing wetlands in villages of Tehran Province. Models and methodologies for wetland utilization worldwide and in Iran were collected, and conceptual models were designed according to Iranian standards. Data layers based on three key criteria, namely technical, socio-economic, and environmental factors, were classified. Relevant maps were developed and overlaid using a Geographic Information System (GIS). The findings indicate that approximately 49 villages, primarily located in the western half of Tehran Province, demonstrated the highest suitability for constructing wetlands. Among these villages, 12 are prioritized by the Department of Rural Water and Wastewater in Tehran Province for the development of wastewater treatment systems, with wetland technology being recommended as the preferred option.
