Abstract

In this study, the basic mechanisms of Fenton, electro-Fenton and photo-electro-Fenton, known as advanced oxidation processes, and the effects of selected experimental operating parameters on the efficiency of these processes in the treatment of leachate are discussed. Experimental studies on leachate treatment have shown that advanced oxidation processes can be used to achieve rapid oxidative degradation of organic pollutants. Therefore, the use of Fenton and related processes in the treatment of leachate is widely discussed in the literature. During the Fenton reactions, hydrogen peroxide (H2O2) is activated by iron to produce hydroxyl radicals (OH●) in the acidic environment, and the formed OH● removes resistant organic compounds in the leachate. Although the discharge standards expressed in the Water Pollution and Control Regulation in force in our country are mostly not met, it is understood that advanced oxidation processes are quite effective in reducing very high dissolved pollutant concentrations. For this reason, it is recommended to use such techniques together with another treatment method in the form of pre-treatment or post-treatment in the treatment of leachate.

Özet

Bu çalışmada, ileri oksidasyon prosesleri olarak bilinen, Fenton, elektro-Fenton ve foto-elektro-Fenton’un temel mekanizmaları ve sızıntı suyu arıtımında seçilen deneysel çalışma parametrelerinin bu proseslerin verimliliğine etkileri tartışılmıştır. Sızıntı suyu arıtımı ile ilgili deneysel çalışmalar, organik kirleticilerin hızlı oksidatif bozunmasını sağlamak için ileri oksidasyon proseslerinin kullanılabileceğini göstermiştir. Bu nedenle, sızıntı suyunun arıtımında, Fenton ve ilgili proseslerin kullanımı literatürde yaygın olarak tartışılmaktadır. Fenton reaksiyonu sırasında, asidik ortamda hidroksil radikalleri (OH●) üretmek için hidrojen peroksit (H2O2) demir tarafından aktive edilir ve oluşan OH● sızıntı suyundaki dirençli organik bileşikleri giderir. Ülkemizde yürürlükte olan Su Kirliliği ve Kontrolü Yönetmeliği'nde ifade edilen deşarj standartları çoğunlukla sağlanmasa da ileri oksidasyon proseslerinin çok yüksek çözünmüş kirletici konsantrasyonlarını azaltmada oldukça etkili olduğu anlaşılmaktadır. Bu nedenle sızıntı suyu arıtımında bu tür tekniklerin ön arıtma veya arıtma sonrası şeklinde başka bir arıtma ile birlikte kullanılması tavsiye edilir.
