چکیده
این پژوهش با هدف ارزیابی فنی، زیست‌محیطی و مدیریتی سیستم فاضلاب شهری ایلام و شناسایی چالش‌های زیرساختی و بهره‌برداری آن انجام شده است. با توجه به رشد جمعیت، توسعه سریع شهری، فرسودگی بخشی از شبکه جمع‌آوری، ظرفیت محدود تصفیه‌خانه و شرایط اقلیمی سرد ایلام، مدیریت فاضلاب شهری در این شهر با مسائل جدی روبه‌رو است. نتایج بررسی نشان می‌دهد که کاهش دما موجب افت راندمان فرآیند‌های بیولوژیکی تصفیه، به‌ویژه حذف BOD، شده و فرسودگی شبکه نیز خطر نشت فاضلاب و آلودگی منابع آب سطحی و زیرزمینی را افزایش می‌دهد. همچنین ترکیبی بودن سیستم فاضلاب و ورود رواناب‌های سطحی در زمان بارندگی، فشار مضاعفی بر خطوط انتقال و تصفیه‌خانه وارد می‌کند. در این پژوهش، راهکار‌هایی مانند نوسازی شبکه‌های فرسوده، استفاده از فناوری‌های مقاوم در برابر سرما، جداسازی فاضلاب از آب‌های سطحی، پایش هوشمند شبکه و استفاده مجدد از پساب تصفیه‌شده برای مصارف کشاورزی و فضای سبز پیشنهاد شده است. در مجموع، ارتقای زیرساخت‌ها و مدیریت یکپارچه فاضلاب می‌تواند نقش مؤثری در کاهش آلودگی، حفاظت از منابع آب و تحقق توسعه پایدار شهری در ایلام داشته باشد.

چکیده English

This study aims to evaluate the technical, environmental, and managerial aspects of the urban wastewater system in Ilam, with an emphasis on infrastructural and operational challenges. Due to population growth, rapid urban development, deterioration of parts of the collection network, limited wastewater treatment capacity, and Ilam’s cold climatic conditions, urban wastewater management in the city faces significant challenges. The findings indicate that low temperatures reduce the efficiency of biological treatment processes, particularly BOD removal, while the aging sewer network increases the risk of wastewater leakage and contamination of surface and groundwater resources. Moreover, the combined sewer system and the inflow of stormwater during heavy rainfall place additional pressure on transmission lines and treatment facilities. The study proposes solutions such as rehabilitation of deteriorated sewer networks, application of cold-resistant treatment technologies, separation of wastewater from stormwater, implementation of smart monitoring systems, and reuse of treated effluent for agriculture and urban green spaces. Overall, improving wastewater infrastructure and adopting integrated management approaches can significantly reduce pollution, protect water resources, and support sustainable urban development in Ilam.
