Abstract
Zgłoszenie dotyczy sposobu wytwarzania bakterii nitryfikacyjnych AOB (ammonia oxidizing bacteria), przeznaczonych do komory osadu czynnego, w którym prowadzi się skróconą nitryfikację, pełną nitryfikację lub wytwarza się azotyny na potrzeby procesu anammox. Sposób polega na tym, że do wsadowego reaktora hodowlanego, wprowadza się zaszczep osadu czynnego, zawierający bakterie z grupy AOB (ammonia oxidizing bacteria) oraz NOB (nitrite oxidizing bacteria) i hoduje się bakterie nitryfikacyjne AOB przy jednoczesnym inhibitowaniu wzrostu bakterii NOB, poprzez traktowanie zaszczepu wolnym amoniakiem (FA), generowanym w trakcie jednoczesnego napełniania reaktora ściekami, o dużym stężeniu azotu amonowego, przy stężeniu wolnego amoniaku wystarczającym do inhibicji bakterii NOB, korzystnie utrzymywanym w granicach 0,2 - 3,6 g N - NH3/m3. Ponadto reguluje się ilość wprowadzanych do reaktora ścieków, podczas pojedynczego napełniania oraz objętość wprowadzanego do reaktora ze ściekami zaszczepu. W procesie hodowli bakterii AOB utrzymuje się wiek osadu w zakresie od 1 - 10 dób, stężenie tlenu w granicach od 0,5 - 2,5 g O2/m3, temperaturę w zakresie od 20 - 40°C, pH od 6,5 - 8,0, a stężenie osadu w zakresie 1 - 10 kg sm/m3.
