Zeytinyağı Endüstrisi Atıksularının Arıtımında Fungal Defenolizasyonun Önemi

Abstract

The main problem at discharging black water after oil production is lack of environmentally and economic discharge method. Biochemical treatment of olive-mill wastewater is limited due to high organic load and COD/BOD ratio. For this reason the constituted systems are highly expensive during investment and operating. During olive oil production olives are smashed and they are containing toxic organics. That’s why these wastes can not be directly treated with biological systems. For reusing as a irrigation or utilization water it should be treated and reduce to acceptable discharge criteria. Most of the countries putting a quota to olive oil producers for discharging black water after treatment. These studies are purse by Environment and Forest Ministry in Turkey.In this study we focused on fungal dephenolization which is predict as a pre operation for treatment. Fungal types were analyzed for dephenolization. At higher enzyme activity conditions its expected a low biomass production level at specially at white-rot fungi. Thus, after dephenolization anaerobic biodegradability yield of black water thoughtfully increase. With searching fungal dephenolization capability, most proper fungi for this study was selected. Waste sludge which will be produced during dephenolization process because of its characteristic can be used as a fertilizer and animal feed and also other area of environmental usage.
