Embodiment example 2

[0040] A biological and hydrophilic filter brush with a novel structure, the preparation method of which comprises the following steps: weighing the following raw materials according to mass percentage: PET 93kg, iron oxide 1.5kg, carbon powder 2.5kg, calcium sulfate 2.5kg, stearic acid Magnesium 0.5kg. After the PET raw material is dried, add iron oxide, carbon powder, calcium chloride and magnesium stearate into the PET and mix evenly, then send the evenly mixed material into the extruder barrel, and set the temperature of the extruder to 235°C , so that the actual temperature is controlled between 230°C and 240°C. After melt blending, it is extruded from a die with a cross-square rhombus in the cavity of the machine head, and the cross-section is cross-square rhombus after cooling, stretching and shaping. bristles. The bristles and stainless steel wires are mechanically shaped, sheared, and cut to length to make filter brushes of different lengths whose bristles are radial...

Embodiment example 3

[0042] A biological and hydrophilic filter brush with a novel structure, the preparation method of which comprises the following steps: weighing the following raw materials according to mass percentage: PP 89kg, iron oxide 2.5kg, carbon powder 3.5kg, calcium sulfate 3.5kg, stearic acid Magnesium 1.5kg. After the PP raw material is dried, add iron oxide, carbon powder, calcium sulfate and magnesium stearate into the PP and mix evenly, then send the evenly mixed material into the extruder barrel, set the temperature of the extruder to 210°C, The actual temperature is controlled between 200°C and 220°C, and after melt blending, it is extruded from a mold with a cross-square rhombus in the cavity of the machine head, and the bristles with a cross-section of a cross-square rhombus are obtained after cooling, stretching, and shaping . The bristles and stainless steel wires are mechanically shaped, sheared, and cut to length to make filter brushes of different lengths with bristles ...

Abstract

The invention relates to a filtering hair brush possesses a novel structure, and biological affinity and hydrophilic performance. The cross sections of brush hair of the filtering hair brush are rhombic; the four edges of the rhombic cross sections are designed to be concave arc; the brush hair is straight or curved; the brush hair is composed of, by mass, 89 to 93% of resin, 1.5 to 2.5% of magnetic powder, 2.5 to 3.5% of carbon powder, 2.5 to 3.5% of a calcium salt, and 0.5 to 1.5% of magnesium stearate. The rhombic brush hair possesses better cutting effect on bubbles, is capable of increasing utilization rate of dissolved oxygen, and reducing oxygen exposure power consumption; adding of auxiliary agents with biological affinity and hydrophilic performance and nutrient slow-release elements is capable of increasing the specific surface area and friction resistance on water current, promoting growth and metabolism of microorganisms, realizing preferable adhesion of microorganisms, increasing film adhesion performance, and improving filtering effect.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a biophilic and hydrophilic filter brush with a novel structure and a preparation method thereof. Background technique [0002] At present, filter tanks, sewage treatment tanks, filter boxes, etc. need to carry out sewage filtration treatment, and most of the current sewage treatment adopts biological filtration, and filtration tools are the core part of biological filtration. A filter brush is a commonly used filter tool. The filter brush is mainly made of iron wire (steel wire) as a skeleton, with many neatly arranged and outwardly stretched bristles on it. The filter brush has the functions of physical filtration and biochemical filtration, and the biochemical filtration is realized by the growth and metabolism of biofilm, that is, the pollutants in the water are used as nutrients for microorganisms to remove pollutants. [0003] The film-hanging property of the filter brush ...
