Özet
Bu çalışmada petrol rafinerisi endüstrisi, endüstriden kaynaklanan atıksu miktar ve özellikleri incelenmiştir. Örnek tesisi olarak TÜPRAŞ İzmit Rafinerisi ele alınmış, rafineriye ait atıksu özellikleri ile mevcut atıksu arıtma tesisi biyolojik arıtma verimi, karbon ve azot giderimi açısından değerlendirilmiştir. Tesiste yaşanan amonyum azotu giderimindeki problemler belirlenmiş, bu problemin çözümüne yönelik nitrifikasyon kinetiği incelenmiştir. Karbon ve azot gideriminin birlikte gerçekleştiği biyolojik sistemlerde nitrifikasyon prosesinin sağlanması için en önemli parametrelerden biri olan maksimum ototrofik spesifik çoğalma hız katsayısı, tesis atıksu ve biyokütlesi kullanılarak yapılan deneysel çalışma ile biyolojik arıtma giriş ve kimyasal arıtma giriş atıksu akımları için incelenmiştir. Aynı zamanda sistemin denitrifikasyon potansiyelini görmek üzere, atıksuda bulunan kolay ayrışabilir KOİ belirlenmesi respirometrik olarak gerçekleştirilmiştir.
In this study, the process and wastewater features of the petroluem refinery industry determined. In the scope of this study, the processes, sources and the constituents of wastewater in TÜPRAŞ İzmit Refinery were investigated. It was found that there were some problems about biological removal of nitrogen in the refinery wastewater treatment system. Meanwhile, theoretical bases of biological removal of carbon and nitrogen were determined. Maximum specific autotrophic growth rate is one of the most important parameter for the systems in which biological removal of carbon and nitrogen occurs. So, some experimental studies were carried out by using the biomass and the biological treatment inlet wastewater stream of TÜPRAŞ İzmit Refinery wastewater system. In addition, same experimental procedure was caried out for the inlet stream of chemical treatment unit in the system. Respirometric evaluation of biological treatment inlet stream was carried out to determine denitrification potantial of the system. Readily biodegradable and total biodegradable fraction of the waste water were examined by the respirometric study.
