✦ Synopsis

The Pond of Dvorec, used for a final treatment of waste waters and a t the same time for fish breeding, has been observed working in an assimilation and later on in a stabilization mode ( SVOBODA and KOUBER). The data on the chemical composition and microbiological properties of its sediments are given. A comparative analysis of the stabilization pond sediments and the sediments of the second stabilization pond have shown a high purification function. An influence of temperature, aeration and thickness of the layer upon a microbial activity and a release of the substance into the water environment were verified in laboratory experiments. A higher layer of sediments can, above all a t increased temperatures, negatively influence the water quality for fish breeding. After composting the drawn pond sediments can be recommended for the fertilization of an agricultural land in near surroundings.
