Aklime edilmiş aktif çamur mikroorganizmaları ile sürekli sistem yukarı akışlı dolgulu kolonda 2,4- diklorofenol gideriminin incelenmesi

Endüstriyel üretim sonrası ortaya çıkan atıksular alıcı ortamlara verilmeden önce atıksu içeriğinde bulunan kirlilik parametrelerinin deşarj kriterlerin altında arıtılması gerekmektedir. Fenol ve türevi olan kimyasal bileşikler endüstriyel üretim sonrası atıksular içerisinde yüksek konsantrasyonda bulunmaktadırlar. Bu fenol ve türevi bileşikleri içeren atıksular kanserojenik ve teratojenik etkilere sahiptir. Bu nedenle bu tip atıksuların alıcı ortamlara arıtılmadan deşarj edilmemesi gerekmektedir. Bu amaçla bu çalışmada 2,4- diklorofenol ile aklime edilmiş aktif çamur mikroorganizmalarının yukarı akışlı olarak poliüretan ile doldurulmuş kolonda 2,4- diklorofenol giderimi incelenmiştir. Aklime edilmiş aktif çamur mikroorganizmaları poliüretan sünger parçaları üzerine immobilize edilmiş ve yukarı akışlı dolgulu kolonda 2,4-dikolorofenolün sürekli sistemde 90 gün boyunca arıtımı incelenmiştir. Elde edilen sonuçlara göre en optimum 500 mg/L 2,4-dikolorofenol komsatrasyonunda %83 KOİ ve %86 fenol giderimi sağlanmıştır.

Investigation of 2,4- dichlorophenol removal in continuous system upflow filled column with activated sludge microorganisms

The pollution parameters in the wastewater must be treated below the discharge criteria before the wastewater generated after industrial production is discharged to the receiving environment. Phenol and its derivatives are found in high concentrations in wastewater after industrial production. Wastewater containing this phenol and its derivatives have carcinogenic and teratogenic effects. Therefore, this type of wastewater should not be discharged to receiving environments without treatment. For this purpose, in this study, the removal of 2,4-dichlorophenol in a column filled with polyurethane upstream of activated sludge microorganisms activated with 2,4-dichlorophenol was investigated. Activated sludge microorganisms were immobilized on polyurethane sponge pieces and the purification of 2,4-dichlorophenol in a continuous system for 90 days in an upstream filled column was studied. According to the results, 83% COD and 86% phenol removal was achieved at the optimum 500 mg / L 2,4-dichlorophenol compensation.
