Embodiment 1

[0031] see Figure 4 As shown, a kind of high-efficiency hydrophilic biological filler 7 for sewage treatment of the present invention comprises polypropylene fiber silk 5, and diameter is 0.3-0.7mm, and length is determined according to actual needs, and modified activated carbon 6 is solidified on its surface, The modified activated carbon 6 is impregnated with a trace metal catalyst, and the trace metal catalyst is one of the trace metal elements Fe, Co or Ni that promote the growth of microorganisms.

[0032] The modified activated carbon is evenly fixed on the fiber filaments with a binder, and the active points of the activated carbon are not wrapped by the binder.

Embodiment 2

[0034] See attached Figure 1-5 As shown, a high-efficiency hydrophilic biological filler device for sewage treatment includes a frame 2, a fixed shaft 4, and a fiber filament 5, and the fixed shaft 4 is parallel and vertically uniformly fixed in the frame 2 , the fiber filament 5 is evenly fixed on the fixed shaft 4 from top to bottom in the shape of a brush, the surface of the fiber filament 5 is solidified with modified activated carbon 6, and the modified activated carbon 6 is impregnated with a small amount of metal catalyst.

[0035] The frame 2 is in the shape of a cube, and a crossbeam for fixing the fixed shaft 4 is correspondingly provided at the top and bottom, and the crossbeam is parallel to one side of the frame; the two ends of the fixed shaft 4 are fixed on on the beam.

[0036] The frame 2 is made of stainless steel or plastic material.

Embodiment 3

[0041] Preparation method of the present invention:

[0042] First, according to the traditional method, the polypropylene raw material is put into the injection molding machine, the polypropylene is heated to melt, drawn into filaments through a mold, and cooled by cold water to form fiber filaments 5 with a diameter of 0.5mm, and then cut into lengths and lengths of 10cm.

[0043] The material of the fixed shaft 4 is high pressure polyethylene, which is made into a rope structure. The fiber filament 5 is centered on the fixed shaft 4 and wound on the fixed shaft 4 in layers in parallel, and the whole is in the shape of a brush.

[0044] According to the traditional method, the activated carbon is impregnated in a liquid containing a metal catalyst Fe with a concentration of 5-10% by weight. The metal catalyst is gradually adsorbed on the surface of the activated carbon. After the impregnation is balanced, the activated carbon particles are separated from the liquid. Drying,...

Abstract

The invention relates to high-efficiency hydrophilic biological stuffing and device applied to sewage treatment. The biological stuffing is prepared from stuffing, wherein modified activated carbon is cured on the surface of the stuffing, a trace metal catalyst is dipped into the modified activated carbon, and the stuffing is elastic stuffing; the device is used for fixing the biological stuffing. The biological stuffing can be used for treating sewage and repairing a water body through a biological membrane method, and has the advantages of being strong in hydrophilia, large in specific surface area, quick in biofilm formation speed, high in biofilm formation amount, not prone to falling down, capable of improving microbial activity, convenient to install and the like.

Description

technical field [0001] The invention relates to a high-efficiency hydrophilic biological filler and a device for sewage treatment, belonging to the technical field of sewage treatment and water restoration. Background technique [0002] The biofilm method is a method of treating organic sewage by using microorganisms (ie, biofilm) attached to the surface of the filler. Biofilm is an ecosystem composed of highly dense aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa and algae. The filler is the carrier of the biofilm, and its function is to provide a surface for the growth of microorganisms. Under the condition that other conditions required for microbial growth are suitable, the more effective biofilm that grows in the filler per unit volume and the larger the contact area between microorganisms and pollutants, the better the sewage treatment effect, so the performance of the filler determines the efficiency of sewage treatment. Effect. [0003]...
