- In this work, the semi-synthetic wastewater made of the leachate derived from non-hazardous municipal waste landfill in Kozodrza (south-eastern Poland) and supplemented by ammonium, was treated in hybrid SBRs to assess the removal efficiency of organic compounds, including humic substances and dissolved fractions, depending on the technological conditions. The technological layout variants concerned both the volumetric proportions of aerated and anoxic zones (0.33 and 0.66) as well as the N/C ratio (0.1 and 0.2). It was found that the efficiency of organic compounds removal (expressed as COD, BOD5 and TOC) was influenced by the geometry of oxygen supply; in the SBRs operating with 0.33 ratio, it was significantly higher compared to that with 0.75 ratio. The analysis also revealed that the N/C ratio set at 0.1 resulted in higher treatment efficiency than that obtained for 0.2. The composition of dissolved organic fractions in outflows was also related both with the SBRs geometry and the N/C ratio. It was found that proportions of TOC and humic substances were significantly lower in the SBRs operating with aeration geometry of 0.33, compared to the ones working with 0.66. Moreover, the N/C ratio of 0.1 led to a higher content of dissolved humic substances and COD in outflows.
