Problems solved by technology

These existing fillers have certain limitations in film-hanging speed and processing capacity. For example, when honeycomb fillers are used, under high load conditions, the biofilm becomes thicker and it is easy to block the fillers; while the fibrous fillers are resistant to Low impact strength, susceptible to crushing from processing equipment

Embodiment Construction

[0030] The present invention is specifically described below through the examples, the examples are only used to further illustrate the present invention, and cannot be interpreted as limiting the protection scope of the present invention, some non-essential claims made by those skilled in the art based on the above-mentioned content of the present invention Improvements and adjustments also belong to the protection scope of the present invention.

[0031] combine Figure 1 to Figure 7 .

[0032] As shown in the figure, the filler for sewage treatment is spherical, including a solid sphere in the center, sheet-shaped fan-shaped expansion areas arranged at intervals on the outer layer of the solid sphere, and velvet areas on each surface.

[0033] The fan-shaped expansion area is composed of fan-shaped sheet parts separated by grooves, and the grooves and fan-shaped sheet parts are evenly spaced around the central axis along the same axis.

[0034] There are grooves arranged ...

Abstract

The invention discloses a filling material for sewage treatment and a preparation method of the filling material. The filling material is spherical and comprises a solid sphere in the centre, a sheet-like fan-shaped expansion area and a wool area on various surfaces, wherein the sheet-like fan-shaped expansion area and the wool area on various surfaces are arranged outside the solid sphere at intervals. The preparation method comprises the steps of manufacturing a spherical basal body, forming a fan-shaped surface in the expansion area, splitting and the like. By means of the unique structure and the process thereof, the filling material disclosed by the invention is good in oxygenizing efficiency and rapid to hang; the specific surface area of the filling material is high; attachment of microorganisms is promoted through the fan-shaped wool area; an aerobic state is formed in the sphere; an anoxic state is formed even in the spherical centre; a biological membrane has multiple varieties of the microorganisms, long food chain and higher processing capacity; the filling material is simple to install and convenient to operate and manage; the basal body shape of the filling material is a sphere; under the stirring of aerated bubbles, the filling material can rotate at high speed; therefore, the filling material is low in resistance and mould releasing and updating are easy; the filling material takes synthetic fibre polyurethane, which has good hydrophilia, as a substrate material.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to the technical field of sewage treatment, and specifically relates to a filler for sewage treatment and a preparation method thereof. Background technique [0002] Biological filler is a matrix with artificially controllable physical and chemical properties that is conducive to the rapid attachment and growth of microorganisms. It is modified and constructed by special processes. It is the core component material of contact oxidation in sewage treatment projects. Microorganisms form biofilms on the surface of fillers. Promote water purification. The structure, form and material of the filler are directly related to the treatment performance of the sewage treatment system, the ease of operation and maintenance, etc. [0003] The types of fillers are divided into spherical, granular, flake, columnar, fibrous, honeycomb, etc. according to the shape; according to the...
