چکیده

این پژوهش که با هدف آشناسازی نیروی انسانی شاغل در صنعت آب و فاضلاب کشور با ویژگی‌ها و مزایای استفاده از هواده‌های عمقی به عنوان جایگزین هواده‌های سطحی و نیز امکان‌سنجی استفاده از آن در فرآیندهای لاگون هوادهی، صورت پذیرفته با استفاده از روش توصیفی از نوع تحلیل اسنادی، گزارش‌شده است. پژوهش حاضر در وهله اول، به منظور ارتقای کیفیت و توانمندی نیروی انسانی، فرایندهای هوادهی در لاگون‌ها را بررسی، انواع روش‌های مربوط به هر یک را بیان و سپس انواع هواده‌ها اعم از هواده‌های عمقی، مکانیکی سطحی، زیرسطحی و همچنین هواده‌های پمپی، نحوه عملکرد و عوامل تأثیرگذار بر این هواده‌ها را موردبررسی قرار داده است که آگاهی از این امور می­تواند موجب بهبود سطح علمی، آشنایی با پیشرفت‌های روز دنیا و درنتیجه بقا و حیات بیشتر سازمان‌های مربوطه شود. در انتها نیز با بهره گرفتن از نتایج حاصل از سایر پژوهش‌ها، مقایسه‌ای بین دو روش صورت گرفته است که نتیجه حاصل‌شده نشان می­دهد استفاده از هواده‌های عمقی به جای هواده‌های سطحی، کاهش حدود 78/ 19 درصد در انرژی مصرفی و درنتیجه صرفه اقتصادی و افزایش راندمان شاخص‌های گوناگون سنجش آلودگی پساب را به همراه خواهد داشت که می­توان آن را گامی مؤثر در راستای مدیریت درست و صحیح منابع و ایجاد توسعه‌ی پایدار در صنعت آب و فاضلاب کشور دانست.

چکیده [English]

This study is performed with the purpose of familiarity of human force working in water and wastewater industry of the country with features and advantages of using deep Aerators as a replace for surface Aerators and also feasibility for using it in Aerated Lagoons processes by using descriptive method from the type of document analysis. Present study in the first step is investigated for improving quality and empowerment of human force of aeration processes in Lagoons and explains related types of methods to each one and then the types of Aerators such as deep, surface mechanical and undersurface Aerators and also pump Aerators of performance method and effective factors on it are investigated that informing these affairs can cause the improvement of scientific level, familiarity with new developments in the world and at last remaining and life of more related organizations. At last by utilizing results arising other researches, a comparison is performed between two methods that the result shows that using deep Aerators instead of surface Aerators had 19.78 percent decline in consumed energy and as a result it will be along with economic saving and increasing efficiency of multiple indices for evaluating waste pollution that we know it as an effective step through correct management of resources and creating sustainable development in water and wastewater industry of the country.
