المعالجة الثانوية هي عملية معالجة لمياه الصرف الصحي (أو الصرف الصحي ) لتحقيق درجة معينة من جودة النفايات السائلة باستخدام محطة معالجة مياه الصرف الصحي مع فصل الطور المادي لإزالة المواد الصلبة القابلة للاستقرار وعملية بيولوجية لإزالة المركبات العضوية المذابة والمعلقة. هذا النوع من المعالجة يمكن تسميتها بالمياه العادمة المعالجة الثانوية. المعالجة الثانوية هي جزء من تسلسل معالجة مياه الصرف الصحي يزيل المركبات الذائبة والغروانية المقاسة حسب الطلب على الأكسجين الكيميائي الحيوي (BOD). يتم تطبيق المعالجة الثانوية بشكل تقليدي على الجزء السائل من مياه الصرف الصحي بعد إزالة المعالجة الأولية للمواد الصلبة القابلة للترسيب والمواد العائمة. عادة ما يتم إجراء المعالجة الثانوية بواسطة الكائنات الحية الدقيقة المائية الأصلية في موطن هوائي مدار. تستهلك البكتيريا والبروتوزوا الملوثات العضوية القابلة للتحلل (مثل السكريات والدهون وجزيئات الكربون القصيرة السلسلة العضوية من المخلفات البشرية ونفايات الطعام والصابون والمنظفات) أثناء التكاثر لتشكيل خلايا المواد الصلبة البيولوجية. عمليات الأكسدة البيولوجية حساسة لدرجة الحرارة بين 0 و40 درجة مئوية، يزداد معدل التفاعلات البيولوجية مع درجة الحرارة. تعمل معظم السفن الهوائية السطحية بين 4 و32 درجة مئوية. (ar) Secondary treatment is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option. A "primary treatment" step often precedes secondary treatment, whereby physical phase separation is used to remove settleable solids. During secondary treatment, biological processes are used to remove dissolved and suspended organic matter measured as biochemical oxygen demand (BOD). These processes are performed by microorganisms in a managed aerobic or anaerobic process depending on the treatment technology. Bacteria and protozoa consume biodegradable soluble organic contaminants (e.g. sugars, fats, and organic short-chain carbon molecules from human waste, food waste, soaps and detergent) while reproducing to form cells of biological solids. Secondary treatment is widely used in sewage treatment and is also applicable to many agricultural and industrial wastewaters. Secondary treatment systems are classified as fixed-film or suspended-growth systems, and as aerobic versus anaerobic. Fixed-film or attached growth systems include trickling filters, constructed wetlands, bio-towers, and rotating biological contactors, where the biomass grows on media and the sewage passes over its surface. The fixed-film principle has further developed into moving bed biofilm reactors (MBBR) and Integrated Fixed-Film Activated Sludge (IFAS) processes. Suspended-growth systems include activated sludge, which is an aerobic treatment system, based on the maintenance and recirculation of a complex biomass composed of micro-organisms (bacteria and protozoa) able to absorb and adsorb the organic matter carried in the wastewater. Constructed wetlands are also being used. An example for an anaerobic secondary treatment system is the upflow anaerobic sludge blanket reactor. Fixed-film systems are more able to cope with drastic changes in the amount of biological material and can provide higher removal rates for organic material and suspended solids than suspended growth systems. Most of the aerobic secondary treatment systems include a secondary clarifier to settle out and separate biological floc or filter material grown in the secondary treatment bioreactor. (en) |
