Abstract

Alkaloid Endüstrisi çıkış
suları yüksek konsantrasyonlu organic madde, alkalinite, tuzluluk, renk, sülfat
içerir. Bu çalışmada sözkonusu kompleks endüstriyel atıksularının arıtımı, iki
kademeli anaerobik rektörlerlerde denenmiştir. KOİ, iletkenlik, pH, alkalinite,
sülfat, TKN’nin anaerobik arıtmaya etkileri değerlendirilmiştir. Reaktörler,
atıksu ile doldurulduğunda OLR 1-3kgCOD/m³gün iken bile uçucu yağ
asitlerinin birikimi tespit edilmiştir. Ancak seyreltme yapılmış ve iletkenlik 20
mS/cm’e düşürülmüştür bu durumda OLR 7-8kgCOD/m³gün’e çıkarılmış ve
organik madde arıtımı görülmüştür. Bu çalışma ile, yüksek konsantrasyon içeren
alkaloid endüstrisi atıksularının anaerobik çürütme ile arıtılabilirliği ve
önemli ölçüde KOİ arıtımı sağlanabildiği görülmüştür.

TREATABILITY OF OPIUM ALKALOID INDUSTRY WASTEWATERS BY ANAEROBIC PROCESSES

Abstract

The effluents from alkaloid industry contain high levels of organic matter, alkalinity, salinity, color and sulphate. The treatment of this complex industrial wastewater was attempted in two stages anaerobic reactors. The effects of COD, conductivity, pH, alkalinity, sulphate and TKN on anaerobic treatment were evaluated. When the reactors were fed with original wastewater, VFA’s were accumulated in the presence of 25,794 mg/L COD and 30.2 mS/cm conductivity of the raw opium wastewater even at OLR of 1-3 kgCOD/m3day. However, stepwise dilution was applied and COD removal of 90% was achieved at OLR of 7-8kgCOD/m3day as the conductivity and COD were reduced to 20 mS/cm 20,000 mg/L, respectively. Based on the findings of this study, highly concentrated wastewaters of opium alkaloid industry wastewaters can be treated with anaerobic digestion and significant reduction of COD can be achieved.
