Abstract


The aim of presented study was to analyse and compare the nitrogen compounds in waste waters from a swine farm from the west of Romania and the environmental impact on the quality of surface water and groundwater. Water samples were taken from sites likely to be potentially sensitive to pollution, above, near and below the waste water discharge in the Mureş river and biopond units. Nitrogen concentrations from 652 mg/l at the pomp station 1 to 12.1 mg/l downstream 1 km after the discharge in the Mureş stream exceed the standard limits accepted for the surface waters. As regarding the ammonia concentrations are also very high, in the analysed samples for the old cleaning system, but lies under the admitted limits in the new system of wastewater cleaning. In conclusion, wastewater from Periam swine farm had a minor pollution impact for surface waters including for Mureş River, while in the new system some values for the nitrogen compounds lies over those obtained in the old system of wastewater cleaning.
