Municipal wastewater contains both biodegradable and non-degradable pollutants. Moreover, they are present in dissolved, colloidal and particulate forms. These fractions are characterised by various decomposition rates, hence their bioavailability during microbial respiration. It was confirm that biological degradation rate in terms of COD reduction is influenced by particle size speciation. Therefore, the objective of the study was to investigate organic matter (COD) and N fractions during wastewater treatment in treatment wetland with the special respect to vegetative and non-vegetative period. The analyses of samples filtered in the standard way through a 0.45mm pore size filter does not provide reliable information about the dissolved (soluble) and particulate fractions due to the colloids content. Based on content of dissolved, colloidal and particulate forms of organic matter and nitrogen it is possible to estimate their potential for degradations and removal in multistage treatment wetland.
