TREATMENT OF TOXIC POLLUTANTS BY ADVANCED OXIDATION PROCESSES

Abstract

Usage of advanced oxidation processes (AOPs) as a pretreatment or post treatment have showed tremendous potential in order to overcome negative effects on the conventional treatment processes which used for the treatment of industrial wastewater that include various toxic and refractory organic substances, In this study, removal of phenol, 2,4- dichlorophenol solution by using advanced oxidation process (UV/H2O2, Fenton’s Reagent, and Photo-Fenton) was investigated. Based on the phenol and total organic carbon analyzes, it was found that reaction time and oxidant dosage requirement which is needed to almost mineralization and degradation of phenol and 2,4-dichlorophenol solution by photo fenton process is lower than other processes

TOKSİK KİRLETİCİLERİN İLERİ OKSİDASYON PROSESLERİ İLE ARITIMI

Abstract

Toksik ve kalıcı özellikte organik maddeler içeren endüstriyel atıksuların arıtımında kullanılan klasik arıtma yöntemlerinin olumsuz etkilerini engelleyebilmek için ön arıtma veya son arıtma kademesi olarak ileri oksidasyon proseslerinin (İOP) kullanımı son zamanlarda oldukça önem kazanmaktadır. Bu çalışmada, fenol, 2,4-diklorofenol organik maddelerini içeren sentetik atıksuların ileri oksidasyon prosesleri (UV/H2O2, Fenton ve Foto-Fenton) ile arıtılabilirliği araştırılmıştır. Toplam organik karbon ve fenol analizleri sonucunda, FotoFenton prosesi ile fenol ve 2,4-diklorofenol içeren atıksuların tamamen mineralize olması ve parçalanabilmesi için gerekli olan reaksiyon süresi ve oksidan madde gereksiniminin diğer ileri oksidasyon proseslere göre daha az olduğu saptanmıştır
