Embodiment 1

[0017] Embodiment one: see attached figure 1 shown.

[0018] A densely supported filler, including a middle rope 1, and fibers 2 fixed on the middle rope 1. The fibers 2 include several fiber units 3, and each fiber unit 3 wraps around the middle rope 1 in a helical layer. Two fiber units 3 are connected to form a multi-layer spiral, two adjacent layers of fiber units 3 are closely arranged, and two adjacent layers of fiber units 3 are closely attached to each other. The densely supported packing also includes reinforced and supported nylon fibers 4 with a diameter of 0.1-3mm. The reinforced and supported fibers 4 and the fibers 2 are twisted and wound together or adhered together without twisting.

[0019] The angle between the tangent of any point of the multi-layer helix formed by the fibers 2 and the plane perpendicular to the axial direction of the middle rope 1 is α, and the range of the angle α is 1-10 degrees.

[0020] The fiber 2 is composed of 1-10 strands...

Abstract

The invention relates to a compact supporting filler, which comprises a central rope and a fiber fixed on the central rope, wherein the fiber comprises a plurality of fiber units; each fiber unit is wound on the central rope in a way of forming a spiral layer; and every two adjacent fiber units are connected to form a plurality of spiral layers, and are arranged closely and attached. The spiral structure can effectively improve the water distribution and air distribution performance of the filler, fully increase the transfer rate and utilization rate of oxygen and remarkably better biological treatment effects.

Description

technical field [0001] The invention relates to a kind of densely supported soft biomimetic water treatment packing which is used for the treatment of natural water body, sewage or waste water, especially the organic or organic and inorganic hybrid applied in the waste water biological treatment device. Background technique [0002] There are many kinds of fillers for the existing natural water body, waste water or sewage biological treatment. There are fixed fixed fillers that appeared earlier, such as honeycomb fillers; suspension fillers that are widely used at present, such as soft fillers, semi-soft fillers, Elastic three-dimensional packing, combined packing, etc. They each have their strengths and weaknesses. The material of fixed fixed packing is phenolic resin plus glass fiber cloth and fixing agent, unsaturated resin plus glass fiber cloth and curing agent, plastic, etc. The feature is that it is not suitable for clogging, the treatment effect is stable and the s...
