COMPARATIVE STUDIES REGARDING THE NITROGEN COMPOUNDS IN WASTE WATERS FROM SMITHFIELD – PERIAM SWINE FARM, TIMIS COUNTY
Keywords:
nitrates, nitrites, ammonia, nitrogen, swineAbstract
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.
