| Abstract: | The development of a concept of ecological functions of soils has facilitated interdisciplinary studies in various fields of soil science and neighboring sciences. As is shown in this paper, the ecological functions of activated sludge have a lot of features similar to the ecological functions of natural soils. A classification of the major ecological functions of activated sludge is suggested. It is stressed that the role of activated sludge as a protective barrier is particularly important for the biosphere preservation, as the self-purification capacity of many water objects is almost exhausted. In general, activated sludge can be considered a biological reactor of a polyfunctional character. |
