The objective of this study was to determine the effect of advanced oxidation process with the use of Fenton’s reaction on the effectiveness of anaerobic treatment of wastewaters originating from the wood industry that were characterized by a high concentration of formaldehyde. Experiments were established to analyze changes in COD content and in the concentration of formaldehyde in treated wastewaters, additional analyses were carried out to assay quantitative and qualitative changes in the biogas produced. The first stage of the experiment involved analyses of the effectiveness of the tested wastewaters treatment only in the process of methane fermentation. At the second stage of the experiment, the biological process was preceded by chemical pre-treatment of wastewaters with Fenton’s reagent. The conducted study proved that the investigated variants of chemical pre-treatment of wastewaters had a significant effect on increasing the total biogas production. In contrast, no significant effect of the applied technology was demonstrated on changes in the concentration of the analyzed contaminants in the treated wastewaters.

Celem prowadzonych badań było określenie wpływu procesu pogłębionego utleniania z zastosowaniem reakcji Fentona na efektywność beztlenowego oczyszczania ścieków pochodzących z przemysłu drzewnego, które charakteryzowały się wysoką koncentracją formaldehydu. W eksperymentach analizowano zmiany wartości ChZT oraz koncentracji formaldehydu w ściekach oczyszczonych, badano również zmiany ilości i składu jakościowego powstającego biogazu. W pierwszym etapie doświadczenia analizowano efektywność oczyszczania testowanych ścieków jedynie w procesie fermentacji metanowej. W drugiej części eksperymentu proces biologiczny poprzedzono wstępnym oczyszczaniem chemicznym z zastosowaniem odczynnika Fentona. Przeprowadzone badania udowodniły, iż testowane warianty wstępnej chemicznej obróbki ścieków wpłynęły istotnie na zwiększenie całkowitej ilości produkowanego biogazu. Nie stwierdzono natomiast znaczącego wpływu zastosowanej technologii na zmiany koncentracji analizowanych wskaźników zanieczyszczeń w ściekach oczyszczonych.
