Embodiment 1

[0067] The preparation of novel biomagnetic ceramsite filler for water treatment comprises the following steps:

[0068] S1: Magnetic powder activation: use ferric oxide powder as magnetic powder, soak and activate in glutaraldehyde to obtain activated magnetic powder;

[0069] S2: Ingredients: Mix ceramsite composed of bauxite and clay, activated magnetic powder, borax, and titanium dioxide according to the following ratio: 25 parts of bauxite, 10 parts of clay, 20 parts of magnetic powder, 1 part of borax, and 1 part of titanium dioxide , and stir evenly to obtain the mixed material A;

[0070] S3: Granulation and drying: Send the mixed material A in S2 into the magnetic microbubble stirring and mixing device, and mix it with water according to the weight ratio of 1:0.45 to obtain the mixed material B, and then mix the mixed material B Put it into a granulator to prepare a spherical mixture material with a diameter of 6mm, then put the spherical mixture material into a dryi...

Embodiment 2

[0077] The difference from Example 1 is:

[0078] The magnetic powder in S2 is composed of ferroferric oxide and ferric oxide mixed in an equal weight ratio;

[0079] The composition of the mixed material A in S2 is: 22 parts of bauxite, 18 parts of sea mud clay, 30 parts of magnetic powder, 3 parts of borax, and 2 parts of titanium dioxide;

[0080] The mixed material B in S3 is granulated into a 7mm spherical mixed material, and the drying time is 1.5h;

Embodiment 3

[0082] The difference from Example 1 is:

[0083] The magnetic powder in S2 is composed of ferric oxide and ferric oxide in a weight ratio of 3:1;

[0084] The composition of the mixed material A in S2 is: 25 parts of clay, 20 parts of mudstone, 40 parts of magnetic powder, 5 parts of borax, and 3 parts of titanium dioxide;

[0085] The mixed material B in S3 is granulated into a 8mm spherical mixed material, and the drying time is 2h;

[0086] The drying time in S8 is 2h.

[0087] The magnetic microbubble stirring and mixing device used in the above-mentioned embodiment 1-3 comprises:

[0088] The variable cross-section water molecule destruction chamber 2-1 is provided with a passage for water to pass through and a magnet outside the passage. The cross-section of the passage is a variable cross-section, and the magnet can magnetize water. One end of the destruction chamber 2-1 is provided with a water inlet pipe 2-2, and one end is provided with a water outlet pipe 2-3, a...

Abstract

The invention discloses a preparation method and equipment for novel biomagnetic ceramsite filling for water treatment. The preparation method comprises the steps of mixing activated magnetic powder,ceramsite, borax and titanium dioxide in a certain proportion, then mixing with water through a magnetic microbubble stirring and mixing device, performing granulation, drying, calcining, water washing, drying and magnetizing to form a magnetic ceramsite filling matrix, loading a surface material comprising coal, clay, neodymium iron boron and water on the surface of the magnetic ceramsite fillingmatrix in a rotary spray load device, and performing secondary drying, calcining and cooling to form the biomagnetic ceramsite filling. Membrane hanging is more easier; the prepared biomagnetic ceramsite filling has a promotion effect on microorganism aggregation of a biological membrane, so that the specific surface area of the surface of the biological membrane is increased; a removal effect ofthe biological membrane on pollutants is improved; ammonia-nitrogen removal efficiency can be greatly improved; and the popularization and application of the method and the equipment in actual sewage(waste water) biotreatment are facilitated.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a preparation method and equipment for a novel biomagnetic ceramsite filler for water treatment. Background technique [0002] The enhanced biological treatment of high ammonia nitrogen wastewater has always been a hot spot and difficulty in the field of environmental protection. Conventional biological treatment of high ammonia nitrogen wastewater cannot meet the requirements of the existing sewage discharge standards. Magnetic-biological composite sewage treatment technology is a new bioaugmentation technology. Studies have shown that the existence of magnetic field will have various effects on microbial metabolism and microbial activity. This is the theoretical basis for applying magnetic field to sewage biological treatment. At the same time, because the magnetic-biological composite sewage treatment technology has the advantages of simple operation, wide applica...
