Zoology . The head: Dementyev M. S. CHANNELS, AS THE BASIS OF WORKING OUT OF SMALL TREATMENT FACILITIES FOR CATTLE-BREEDING ECONOMY In modern economic conditions working out of the elementary treatment facilities accessible to small farms is actual. From set of variants of the decision of a problem we had been chose process of self-cleaning of water by means of an intensification of bioprocesses directly on a place of formation of liquid cattle-breeding drains flowing down in reservoirs on an earth surface. It can look, as the cascade of small capacities located on a drain way to the river or lake. In the first there is a subsidence of firm particles on a bottom, and therefore it is subject to constant cleaning. In the second phytoplankton development begins, there is a complex of microorganisms which utilise organic chemistry and surplus of nitrogen. For clarification of water for the third us have been chosen rachki-dafnii. Thereupon the purpose of the given work was working out of technology of cultivation in clearing channels.
