Abstract AR
تلعب البكتيريا دورا مهما في أكسدة و استقرار المواد العضوية في المخلفات السائلة في محطات المعالجة.
تعرض هذه الورقة لإنشاء نموذج رياضي لدراسة تأثير الكروم على البكتيريا الهتروتروفيكية في أحواض الأكسدة.
المعادلة الرئيسية للنموذج هي معادلة هالدين.
يحسب النموذج معدل وفاة البكتيريا مع تغير كل من التركيز الأيوني للهايدروجين (Ph) و تركيز الكروم.
لاختبار النتائج المحسوبة من النموذج أجريت سلسلة من الاختبارات المعملية و بمقارنة النتائج المحسوبة من النموذج و المقاسة وجد أن هناك علاقة جيدة بمعامل ارتباط R2 = 0.87.
Abstract EN
Bacteria play an important role in oxidation and stabilization of organic and inorganic matter in wastewater treatment plant.
This paper presents the development of mathematical model to study the effect of chromium on heterotrophic bacteria in waste stabilization pond.
The governing equation of the model is based on the Haldane equation.
The model developed reflects the mortality rate of heterotrophic bacteria at variable pH and concentration of chromium.
To verify the computed results a series of laboratory experiments has been carried out, the predicted mortality rate was obtained from these models and compared with experimental data.
The correlation coefficient R2 was 0.87.
