Abstract:	The constructed wetland system of Bogdány Petrol Ltd. was formed in the 1970s for the post-treatment of petrochemical wastewater. Before leading to the constructed wetland, the wastewater is treated both mechanically and chemically. The constructed wetland system consists of three ponds with extended vegetation cover. Dominant macrophytes are Phragmites australis, Typha latifolia and Typha angustifolia, while among other plant species, Bidens tripartitus, Carex acutiformis, Ceratophyllum demersum, Lemna minor, Potamogeton pectinatus and Scirpus lacustris can be found on the area. The aim of our research was to examine the effect of the pond-system on removal of organic matters and plant nutrients from the wastewater. Organic matter removal was examined through COD and BOD values, while elimination of main plant nutrients was reflected by the data of different forms of phosphorous and nitrogen.
