The aim of the study was to determine the impact of selected factors on the reduction of organic pollutants, expressed in BOD5 and CODCr, in wastewater treated in a laboratory scale model of moving bed biofi lm reactor (MBBR). The factors included in the experiment: the degree of fi lling the fluidized bed with biomass carriers, hydraulic load, and aeration intensity. The tested model of the bioreactor consisted of five independent chambers with diameter D = 0.14 m and height H = 2.0 m, which were fi lled with biomass carriers at 0%, 20%, 40%, 60%, 70% of their active volume. During the test period, hydraulic loads at the level of Qh1 = 0.073 m3·m-2·h-1 and Qh2 = 0.073 m3·m-2·h-1were applied, which ensured one-day and two-day sewage retention, respectively. The said reactors were subjected to constant aeration at P1 = 3.0 dm3·min-1 and P2 = 5.0 dm3·min-1. The highest efficiency of the reduction of the analysed indicators was demonstrated by reactors filled with carriers in the degree of 40–60%. Based on the statistical analyses (the analyses of the ANOVA variations and the Kruskal-Wallis test) carried out, it was found that the studied factors significantly modified the mutual interaction in the process of reducing BOD5 in treated wastewater of the reactors tested. The significance of the impact of the discussed factors on the values of the studied indicators in treated wastewater depends on mutual interactions between the investigated factors.

Celem badań było określenie wpływu wybranych czynników na zmniejszenie zanieczyszczeń organicznych, wyrażonych wskaźnikami BZT5 i ChZTCr, w ściekach oczyszczanych w modelu reaktora przypływowego ze złożem ruchomym typu MBBR. Czynniki, które uwzględniono w eksperymencie to: stopień wypełnienia złoża nośnikami biomasy, obciążenie hydrauliczne oraz intensywność napowietrzania. Badany model bioreaktora stanowił pięć niezależnych komór o średnicy D = 0,14 m i wysokości H = 2,0 m, które były wypełnione nośnikami biomasy w stopniu: 0%, 20%, 40%, 60%, 70% ich objętości czynnej. W okresie badań zastosowano obciążenia hydrauliczne na poziomie Qh1 = 0,073 m3·m-2·h-1 oraz Qh2 = 0,073 m3·m-2·h-1, co zapewniało odpowiednio jednodobowe oraz dwudobowe zatrzymanie ścieków. Przedmiotowe reaktory poddawane były stałemu napowietrzaniu na poziomie P1 = 3,0 dm,3min-1 oraz P1 = 3,0 dm3min-1 = 5,0 dm3·min-1. Największą skuteczność redukcji analizowanych wskaźników wykazywały reaktory wypełnione kształtkami w stopniu 40–60%. Na podstawie przeprowadzonych analiz statystycznych (analiza wariacji ANOVA oraz test Kruskala-Wallisa) stwierdzono, iż badane czynniki istotnie modyfikowały wzajemne oddziaływanie na siebie w procesie zmniejszania BZT5 w ściekach oczyszczonych badanych. Istotność wpływu omawianych czynników na wartości badanych wskaźników w ściekach oczyszczonych, zależy od wzajemnych interakcji między badanymi czynnikami.
