FIELD: environmental protection; devices for purification of the domestic and some kinds of the industrial waste waters by the method of the biochemical destruction. ^ SUBSTANCE: the invention is pertaining to the devices intended for purification of the domestic and some kinds of the industrial waste waters by the method of the biochemical destruction. The filamentary carrier for the immobilized biomasses includes the woven core consisting of two and not more non-corrodible metallic wires and two synthetic threads, and the filamentary components of the various diameter and the length. At weaving the core the simultaneous interweaving and fixation between the wires of the radial sections of the filamentary components is exercised. The ratio of the minimum and maximum diameters of the polyamide fibers in the filamentary components is within the interval of 1:18-1:20, at that and the percentage of the weight of the polyamide fibers of the maximum diameter varies from 40 up to 90 %, and the pitch along the direct line, which is in parallel to the axis of the parallel axis of the woven core between the points of fixation of the middles of the filamentary components compounds no more than three diameters of the polyamide fibers of the maximum diameter. ^ EFFECT: the technical result of the invention is the increased mass of the immobilized micro-organisms by the filamentary carrier and the increased elasticity of the product; preservation of the preset geometrical parameters of the filamentary carrier at the great linear dimensions of the installations of the biochemical purification. ^ 2 cl, 2 dwg, 1 tbl |
