نمذجة عكارة مياه شرب محطة السن باستخدام شبكات عصبونية ديناميكية
Abstract
إن نمذجة العلاقة بين عكارة مياه الشرب في محطة تنقية مياه الشرب في السن، وبقية بارامترات جودة المياه باستخدام أسلوب الشبكات العصبونية الصنعية الديناميكية يساعد على تحقيق الاستقرار في أداء محطة تنقية مياه الشرب، حيث توفر هذه الشبكات أداةً فعالة للتعامل مع الطبيعة المعقدة، والديناميكية، وغير الخطية لعمليات التنقية، ولديها القدرة على الاستجابة للتغيرات الآنية المختلفة للبارامترات المؤثرة في تنقية المياه.
صمم في هذا البحث أربعة نماذج للشبكات العصبونية الديناميكية ذات التغذية الأمامية والانتشار العكسي للخطأ للتنبؤ بعكارة المياه المرشحة الخارجة من محطة تنقية مياه الشرب في السن، بالاعتماد على بارامترات عكارة وناقلية وpH المياه الخام الداخلة إلى المحطة، بينما استخدمت بيانات عكارة المياه الخارجة من المحطة للتحقق من دقة أداء الشبكة العصبونية الصنعية، حيث أثبتت نتائج الدراسة قدرة الشبكات العصبونية الصنعية الديناميكية في نمذجة ومحاكاة السلوك غير الخطي للعكارة والتنبؤ بقيمها، وهو ما يدعم استخدامها في محطة تنقية مياه الشرب في السن للمساهمة في تحقيق الاستقرار في عمل المحطة.
Modelling the relationship between drinking water turbidity and other indicators of water quality in Al-Sin drinking water purification plant using Dynamic Artificial neural networks could help in the implementation of the stabilization for the performance of the plant because these neural networks provide efficient tool to deal with the complex, dynamic and non-linear nature of purification processes. They have the ability to response to various instant changes in parameters influencing water purification.
In this research, four models of feed-forward back-propagation dynamic neural network were designed to predict the effluent turbidity from Al-Sin drinking water purification plant. The models were built based on turbidity, pH and conductivity of raw water data while the effluent turbidity data were used for verify the performance accuracy of each network. The results of this research confirm the ability of dynamic neural networks in modeling and simulating the non-linearity behavior of water turbidity as well as to predict its values. They can be used in Al-Sin drinking water purification plant in order to achieve the stabilization of its performance.
