Bu makalede; antibiyotik,
renk gibi gelişmekte olan kirleticilerin gideriminde bir fotokatalist olarak
etkinliği kanıtlanmış NFC-doplu Titanyumun, Çorlu ilçesi evsel atıksu arıtma
tesisi giriş suyunda biyolojik olarak parçalanamayan KOİ fraksiyonu üzerindeki etkisini
belirlemeye yönelik deneysel çalışmalar yürütülmüştür. NFC-doplu titanyuma
maruz kalan (ham + fotokatalist) ve maruz kalmayan (ham) atık suların S_I ve
X_I bileşenlerinin belirlenmesi, süzülen atık su ile aynı
konsantrasyonda hazırlanan glikoz reaktörüne paralel olarak çalışan hem ham hem
de filtrelenmiş atıksu reaktörlerinde gerçekleştirilen deney yöntemine
dayandırılmıştır. Bütün reaktörler kesikli modda 30 gün boyunca
çalıştırılmıştır. Konvansiyonel karakterizasyon sonuçlarına göre, incelenen
evsel ham atıksuyun toplam ve çözünmüş KOİ değerleri sırasıyla 535 mg/l ve 315
mg/l olarak  ölçülmüş ve S_T0/C_T0
oranı %59 olarak hesaplanmıştır. Ayrıca, deneysel çalışma sonunda
fotokatalist maruziyeti öncesi ve sonrası COD giderim verimi toplam KOİ için
sırasıyla %67 ve %60, çözünmüş KOİ için %77 ve %75 olarak hesaplanmıştır. Her
iki reaktördeki atıksuların inert KOİ fraksiyonları ise sırasıyla Çözünmüş
İnert KOİ (S_I0) için 23 mg /l ve 9 mg/l, Partiküler inert KOİ (X_I0)
için 56 mg /l ve 60 mg/l ve C_I0/C_T0 oranı da %15 ve %13 olarak
hesaplanmıştır. Tüm bu sonuçlar göstermektedir ki; giriş ham atıksuyunun
fotokataliste maruziyetinden 30 gün sonra, her iki reaktörde inert toplam giriş
KOİ fraksiyonlarında önemli bir değişim gözlemlenmemesine ragmen, ham +
fotokatalist atıksu reaktöründe çözünmüş inert kısmın %2 azaldığı, partiküler
inert kısmın da %2 arttığı görülmüştür. Bunun nedeni NFC-doplu Titanyumun
adsorbsiyon etkisi olarak düşünülebilir.

Evaluation the Impact of NFC-dopped Titania Photocatalyst on Initial Inert COD Fraction of Çorlu Town Domestic Wastewater

Öz

In this paper, experimental studies were carried out to determine the
impact of NFC dopped Titania, which is proven success in emerging pollutants
such as antibiotic and color removal as a photocatalyst, on influent
non-biodegradable COD fraction of Çorlu town domestic wastewater treatment
plant. The determination of S_I and X_I components
of wastewaters which are exposed (raw + photocatalyst) and unexposed (raw) to
the NFC-dopped titania, are based on the experimental method carried out in
both raw and filtred reactors which are run parallel to the glucose reactor
prepared as same  concentration with
filtered wastewater. All reactors had been run thorugh 30 days in batch reactor
mode. According to the results; total and soluble COD were measured as 535 mg/L
and 315 mg/L, repectively and S_T0/C_T0 ratio was
calculated as 59%. Furthermore, at the end of the experimental study, COD
removal ratio for both reactors were calculated as 67 % and 60% for total COD
and 77% and %75 for soluble COD. Inert COD fractions of both wastewaters were
found for Soluble Inert COD (S_I0) as 23 mg /L and 9 mg/L, particulate
inert COD (X_I0) as 56 mg /L and 60 mg/L and C_I0/C_T0
ratio was calculated as 15% and 13%.  These
all results shows that, after photocatalyst exposition, at the end of the 30
days, it was not observed any important variation in terms of inert total COD
fraction between two reactors. Furthermore, it is understood that at the end of
the 30 days, while soluble inert fraction reduces 2%, particulate inert
fraction also increases 2%. The reason of this situation can be thought as the adsorbtion
effect of NFC-dopped Titania.
