Antep Fıstığı İşleme Atıksularının Elektrooksidasyon Yöntemiyle Ön Arıtım Çalışmaları

Öz

İleri oksidasyon prosesleri pek çok endüstri atıksuyunun arıtımı için etkili bir şekilde kullanılmaktadır. Bu çalışmada Antep fıstığı işleme atıksularının elektrooksidasyon yöntemi ile arıtımı araştırılmış ve ön çalışmaların sonuçları verilmiştir. Bu atıksu için KOİ (Kimyasal Oksijen İhtiyacı), TOK (Toplam Organik Karbon) ve TF (Toplam Fenol) giderimleri için elde edilen veriler incelenmiştir. Anot materyali olarak grafit katot materyali olarak paslanmaz çelik plakalar kullanılmıştır. Kesikli reaktörde yapılan denemelerde çözelti başlangıç pH değeri ve karıştırma hızı (100-600 rpm) gibi parametrelerin KOİ, TOK ve TF arıtımı üzerine etkileri incelenmiştir. Elde edilen bu ön arıtım verilerine göre fıstık sanayi işleme atıksularının elektrooksidasyon yöntemi ile arıtılabileceği ve biyolojik arıtıma girmeden önce bir ön arıtım sistemi olarak önerilebileceği söylenebilir

Pre-Treatment Studies of Pistachio Processing Wastewaters by Electro-Oxidation Methods

Öz

Advanced oxidation processes are used effectively for many industrial wastewater treatments. In this

study, pistachio processing wastewater of treatment was investigated by electro-oxidation method and presented the

results of pre-treatment. For this wastewater, COD (Chemical Oxygen Demand), TOC (Total Organic Carbon) and

TF (Total Phenols) for removal the data obtained were examined. Graphite as the anode material and the stainless

steel as the cathode material plates were used. Batch reactor experiments the initial pH value of solution (3-9) and

stirring speed (100-600 rpm) parameters such as, COD, TOC, and TF on the effects of treatment were investigated.

According to data obtained from this pre-treatment with pistachio processing wastewater electro-oxidation method

could be treatment and before entering the biological treatment to be offered as a pre-treatment system can be said.
