Sažetak
Limiting parameters of keeping and housing of animals on slatted floor result in great amounts of slurry .It is a mixture of feces, urine and water, and its environmental disposition is ecologically questioned. Intensive swine production is often accompanied by various environmental problems, the major one being the removal of slurry . The study was conducted on a large pig-breeding farm with all production phases included. The breeding herd, consisting of 1, 600 sows, has a total of 30, 000 weaned piglets and 24, 000 fatterings. The unessential product of this pig breeding farm is about 20, 000 tons slurry per year. The procedure of wastewater purification is based removing the settleable solids in settling basins, wherefrom the liquid phase is being pumped into the system of three flow-through lagoons. From the last lagoon, the effluent is discharged into the reclamation channel where the dilution occurs. After two kilometers, it flows into the nearby river . Investigations were carried out monthly during the current year at several characteristic sites. Physical and chemical parameters relevant for surface water categorization were investigated.
