Harakatlanuvchi yotoqli biofilm reaktori (MBBR) zamonaviy oqova suvlarni tozalashdagi asosiy texnologiyalardan biridir. U suspenziyadagi tashuvchilarga yopishgan biofilm orqali organik moddalarni, ammiak azotini va boshqa ifloslantiruvchi moddalarni samarali yo'qotadi. Yuzaki maydon yuklanish tezligi (SALR)<\/strong> MBBR dizayni va ishlashida eng muhim parametrdir. U to'g'ridan-to'g'ri zarur tashiyuvchi yuzaki maydonni, reaktor hajmini, tozalash samaradorligini va umumiy loyiha iqtisodiyotini belgilaydi.<\/p>\n

\"MBBR<\/p>\n

\n

1. Yuzaki maydon yuklanish tezligi va muhandislik farqi atamasining ikki keng tarqalgan ma'nosi<\/h2>\n
    \n
  • Gidravlik yuzaki yuklash tezligi<\/strong>Kundalik GPD\/ft\u00b2 bo'yicha tozalash inshootining bir birlik yuzaki maydoni (odatda fut\u00b2) orqali o'tadigan suv hajmi. Oddiy diapazon: 300\u20131 200 GPD\/ft\u00b2. Asosan gidravlik quvvat va ajratgich dizaynini baholashda ishlatiladi.
    \nFormula: Umumiy kunlik oqim (GPD) \u00f7 tank sirt maydoni (ft\u00b2).<\/li>\n
  • Organik yuzaki maydon yuklash tezligi (SALR)<\/strong>: MBBR tizimlari uchun haqiqiy asosiy dizayn parametri. Bu kuniga himoyalangan tashuvchi yuzasining birligiga qo'llanadigan ifloslantiruvchi moddaning massasini bildiradi. Odatiy birliklar: g BOD\/m\u00b2\u00b7d, g COD\/m\u00b2\u00b7d yoki g NH\u2084-N\/m\u00b2\u00b7d.
    \nFormula: SALR = ifloslantiruvchining kunlik yuklamasi (g\/d) \u00f7 umumiy samarali tashuvchi yuzaki maydoni (m\u00b2)<\/strong>
    \nIfloslantiruvchining kunlik yuklamasi = Oqim tezligi (m\u00b3\/kunda) \u00d7 Kirish konsentratsiyasi (g\/m\u00b3) \u00d7 Kutilayotgan olib tashlash samaradorligi (%).<\/li>\n<\/ul>\n

    Muhandislik eslatmasi<\/strong>Marketing materiallarida ko'pincha \u201cMBBR ko'proq suvni boshqarishi mumkin\u201dligini ta'kidlash uchun gidravlik yuklashdan foydalaniladi, ammo haqiqiy jarayon dizayni SALRga tayanadi. Juda yuqori SALR qalin biofilm hosil bo'lishiga, kislorod o'tkazuvchanligining cheklanishiga va tozalash samaradorligining pasayishiga olib keladi; juda past SALR esa tashuvchi material va reaktor hajmini behuda sarflashga sabab bo'ladi.<\/p>\n

    3. SALR hisoblash va reaktor dizayni ish jarayoni (muhandislik bosqichlari)<\/h2>\n
      \n
    1. Ifloslantiruvchi yuklamani aniqlang: Oqim \u00d7 Konsentratsiya \u00d7 Maqsadli olib tashlash tezligi.<\/li>\n
    2. Muvofiq SALR ni tanlang: yuqoridagi jadvalga murojaat qiling va xavfsizlik marjasini qo'shing (cho'qqi\/mavsumiy o'zgarishlar uchun 20\u201330% qo'shing).<\/li>\n
    3. Talab qilinadigan umumiy yuzaki maydonni hisoblang: ifloslantiruvchi yukni SALR ga bo'ling.<\/li>\n
    4. Tashuvchini tanlang: Himoyalangan yuzaki maydon odatda 300\u2013800 m\u00b2\/m\u00b3.<\/li>\n
    5. Media hajmini hisoblang: Umumiy yuzaki maydonni tashiyuvchining spesifik yuzaki maydoni bilan bo'ling.<\/li>\n
    6. Reaktor hajmini aniqlang: Media hajmi \u00f7 to'ldirish nisbat (tavsiya etilgan 40\u201370%, ko'pchilik loyihalarda ~50%).<\/li>\n
    7. HRTni tekshiring: suyuqlik reaktor hajmi \u00f7 o'rtacha oqim tezligi (odatda 1\u20138 soat; yuqori yuklama 1\u20132 soat, nitratlanish 3\u20136 soat).<\/li>\n<\/ol>\n

      Misol<\/strong>: Kunlik oqim 1 000 m\u00b3\/kunda, kirish BOD 300 mg\/L, olib tashlash 80%, SALR 15 g BOD\/m\u00b2\u00b7kunda, tashuvchi 500 m\u00b2\/m\u00b3, to'ldirish darajasi 50%.

      \n\u2192 HRT \u2248 1,5\u20134 soat (aeratsiya rejimiga qarab).<\/p>\n

      4. SALR ishlashiga va optimallashtirishiga ta'sir qiluvchi asosiy muhandislik omillari<\/h2>\n
        \n
      • Harorat<\/strong>Reaksiya tezligi har 10 \u00b0C harorat oshganda taxminan ikki barobar oshadi; 10 \u00b0C dan pastda SALR ni 40\u201360% ga kamaytiring. Izolyatsiya yoki ko'p bosqichli dizaynni ko'rib chiqing.<\/li>\n
      • Erigan kislorod<\/strong>Aerob zona 2\u20134 mg\/L (nitrifikatsiya \u22653 mg\/L). Nozik pufakli aeratsiya + avtomatik erigan kislorodni nazorat qilishdan foydalaning (energetika xarajatlarining 60\u201370 foizini tashkil etadi).<\/li>\n
      • pH\/ishqoriylik<\/strong>Nitifikatsiya har bir gramm NH\u2084-N uchun 7,1 g alkalinlikni iste'mol qiladi; denitifikatsiya esa alkalinlikni tiklaydi.<\/li>\n
      • Yetkazib beruvchini tanlash<\/strong>Yuqori himoyalangan yuzaki maydon turlarini afzal ko'ring (masalan, nitritlash uchun K5 800 m\u00b2\/m\u00b3).<\/li>\n
      • Boshlash va ishlash<\/strong>Bosqichma-bosqich yuklash (birinchi hafta 20\u201330%, to'liq yuklamaga asta-sekin o'tish); DO, pH va chiqindi suv sifatini muntazam nazorat qiling.<\/li>\n<\/ul>\n

        5. MBBR tizimlarida optimallashtirilgan SALRning muhandislik qiymati<\/h2>\n
          \n
        • Gidravlik sig'im va tozalash samaradorligini sezilarli darajada oshiradi, shu bilan birga maydonni 30\u201350% ga kamaytiradi.<\/li>\n
        • Shock yuklariga yuqori chidamlilik, qisqa HRT (soatlarda), loy qaytarish talab qilinmaydi, sodda ishlash va texnik xizmat ko'rsatish.<\/li>\n
        • Past energiya va ekspluatatsiya xarajatlari, tizimning uzoq umr ko'rishi, tashuvchilarni almashtirish tezligi <5%\/yil.<\/li>\n
        • Yuk o'zgarishlariga tabiiy ravishda moslashadi; shahar infratuzilmasini yangilash, yuqori kuchga ega sanoat oqova suvlari, akvakultura va boshqalar uchun mos.<\/li>\n<\/ul>\n

          SALRni ilmiy asosda tanlab, joyida suv sifatini sinashni yetkazib beruvchi ma'lumotlari bilan birlashtirish orqali atrof-muhitni muhofaza qilish bo'yicha muhandislik loyihalari samarali, barqaror va iqtisodiy jihatdan barqaror oqova suvlarni tozalashni amalga oshirishi mumkin. Loyihaga xos SALRni optimallashtirish, hisoblash yoki dizayn bo'yicha takliflar (oqim, suv sifati, chiqindilarni chiqarish standarti asosida) uchun iltimos, professional jamoamiz bilan bog'laning.<\/p>\n<\/article>","protected":false},"excerpt":{"rendered":"
