Evsel Atıksuların Solar TiO2 Fotokatalizi ile Dezenfeksiyonu

Yıl 2018, Cilt: 3 Sayı: 2, 39 - 46, 15.10.2018

Öz

Atıksu dezenfeksiyonunun temel amacı, deşarjlar sonucu, yüzeysel sulara
patojenlerin ulaşmasının önlenmesi ve böylece, halk sağlığının korunmasıdır.
Atıksu dezenfeksiyonunda kullanılan klasik yöntemlerin, yan ürün oluşumu,
yüksek enerji gereksinimi ve yüksek maliyet gibi dezavantajları bulunduğundan,
son çalışmalar, güneş ışığına dayalı ileri oksidasyon prosesleri üzerine
yoğunlaşmıştır. Hidroksil radikallerinin oluşumuna dayanan bu prosesler,
sulardaki pek çok kirleticinin ve mikroorganizmanın gideriminde
kullanılmaktadır. Ayrıca, güneş ışığı kullanıldığı için, bu prosesler, çevreye
dost olarak nitelendirilebilir. Bu çalışmada, ileri oksidasyon proseslerinden
olan solar TiO2 fotokatalizi ile evsel atıksuların dezenfeksiyonu
incelenmiştir. Sentetik evsel atıksuların dezenfeksiyonu, solar ışık altında,
farklı TiO2 konsantrasyonlarında (0-0,3-0,5-1-5-10 mg/L)
incelenmiştir. Solar TiO2 fotokatalizinin evsel atıksulardan E.coli
ve E.faecalis gideriminde etkili olduğu belirlenmiştir. E.coli
için elde edilen giderim verimleri, E.faecalis’e göre daha yüksektir. Bu
fark, en belirgin şekilde, 0,5 mg/L TiO2 konsantrasyonu için
gözlenmiş olup, 60 dk.’da E.coli
için elde edilen giderim, 5,45-log iken, E.faecalis için elde edilen
giderim 3,80-log olarak bulunmuştur.
