[Microbial decontamination by aerobic purification of liquid manure from swine-breeding farm complexes].

Studied was the microbial decontamination of swine mature with the employment of a laboratory model of an aerobic lagoon as well as in a purification station, having a mechanical step, two biologic steps, and a facultative lagoon. It was found under modelled conditions that a substantial decontaminating effect was produced with regard to coli bacteria and Salmonella organisms. The effect was less with regard to the microbial count. The studies carried out in stations showed the effectiveness of the individual steps in reducing the microbial content of manure.
