Abstract This research highlights the waste types and their
principal characteristics produced from the main activities in an
investigated livestock farm, especially collected wastewaters from different
zootechnical activity sectors. Six monitoring sectors were selected to
assess the level of polluting load from the discharged effluents. Constant
control of the main imposed quality indicators (pH, COD, BOD, total solids,
ammonia, extractible substances) is obviously required and periodically
reported to water regulatory management authority, as well as the
establishment of viable and efficient directions utilized for the wastes
treatment and recovery on-site (direct possible use). The limiting norms of
the quality indicators controlled in a few sectors (mainly 4 control
sectors) are far exceeded and the trend is to increase the polluting loads,
which requires the adoption of serious local treatment measures and the
continuation of monitoring the quality status of the effluents generated on
the livestock farm. Keywords: environmental protection, wastewater,
livestock farm, quality indicators
