The article presents the quality assessment of the operation of HEID technological line threshing unit in SAATBAU Sp. z o.o. company in Środa Śląska. Evaluation of the CIMBRIA abrasive machine was made based on the macro and micro damages of seeds, which were made after threshing and through determination of seeds germination capacity and energy. Tests were carried out for five corn varieties: Bosman, Sl Normo, Odilo, Okato, Wikana. The calorymetric method was applied for determination of mechanical damages to seeds. The biggest macro-damages were reported at the level of 4.2% and micro-damages at the level of 14.5%. The increased values of damages occurred after threshing. The highest germination capacity was 96%. On this basis it was stated that the quality of the operation of the threshing unit was within the norm.

W artykule przedstawiono ocenę jakości pracy zespołu omłotowego linii technologicznej HEID w firmie SAATBAU Sp. z o. o. w Środzie Śląskiej. Oceny łuszczarki CIMBRIA dokonano na podstawie powstałych po omłocie makro i mikrouszkodzeń ziarna oraz poprzez określenie jego siły i energii kiełkowania ziarna. Badania przeprowadzono dla pięciu odmian kukurydzy: Bosman, Sl Normo, Odilo, Okato, Wikana. Do wyznaczenia uszkodzeń mechanicznych ziarna wykorzystano metodę kolorymetrii. Największe makro- uszkodzenia ziarna stwierdzono na poziomie 4,2%, a mikrouszkodzenia na poziomie 14,5%. Zwiększone wartości uszkodzeń występowały po jego omłocie. Największa siła kiełkowania wynosiła 96%. Na tej podstawie stwierdzono, że jakość procesu eksploatacji zespołu omłotowego odpowiadała normie.

The paper presents the results of research on the effects of removing pollution from domestic wastewater in two beds of constructed wetland systems with vertical flow. Bed I was planted with common reed (Phragmites australis Cav. Trin. Ex Steud.), whereas bed II with Glyceria maxima (Glyceria aquatica L.). The surface of each of the beds amounted to 30 m2, and the hydraulic load of each of them amounted to 0.033 m3·m-2·d-1. The study showed very good results in the removal of most of the analyzed indicators of contamination, which were similar in both analyzed beds. They were, respectively: 91 and 93% – for total suspended solids, 96 and 98% – for BOD5, 96 and 94% – for CODCr, 88 and 86% – for ammonia nitrogen and 87 and 88% – for total phosphorus. Much smaller effects were reported with regard to total nitrogen removal – 55% in bed I with common reed and 54% in bed II with Glyceria maxima. The tested beds also eliminated the number of coliform bacteria and faecal coliform bacteria quite effectively. Average effects of the removal of coliform bacteria in bed I and II were 99.74%, in the case of faecal coliform 98.06% and 97.94% respectively. Values of basic indicators of contamination (total suspended solids, BOD5 and CODCr) in the wastewater discharged from the analyzed beds met the requirements of the Regulation of the Minister of the Environment of 2014. The test results obtained in the first year of operation of the analyzed beds show that neither of the applied plants significantly improves the results of contaminant removal.
