Embodiment 1

[0016] A kind of preparation method of easily degradable biofiller is made by the following steps:

[0017] (1) 8 parts of corn stalks are puffed to form a loose, porous and crispy puffed product, which is cut into several uniform small pieces;

[0018] (2) Put 15 parts of shell powder and puffed corn stalks into an airtight container, rotate the airtight container to fully mix the shell powder and corn stalks, and heat the airtight container during the rotation so that the temperature of the container reaches 100 ℃, after mixing, quickly cool down to 60 ℃ for use;

[0019] (3) Put the mixture in step (2) into a molding machine to form a uniform mixture. The molding machine can be a granulator or an extruder to form a round or cylindrical mixture;

[0020] (4) Grind 8 parts of bamboo and potato into powder, cook with 3 parts of high-density PE, and the temperature can reach up to 125°C, so that bamboo and potato powder and high-density PE can form a mixed paste;

[0021] (5)...

Embodiment 2

[0023] A kind of preparation method of easily degradable biofiller is made by the following steps:

[0024] (1) 6 parts of corn stalks are puffed to form a loose, porous and crispy puffed product, which is cut into several uniform small pieces;

[0025] (2) Put 16 parts of shell powder and puffed corn stalks into an airtight container, rotate the airtight container to fully mix the shell powder and corn stalks, and heat the airtight container during the rotation to make the temperature reach 120 °C, after mixing, quickly cool down to 80 °C for use;

[0026] (3) Put the mixture in step (2) into a molding machine to form a uniform mixture. The molding machine can be a granulator or an extruder to form a round or cylindrical mixture;

[0027] (4) Grind 10 parts of bamboo and potato into powder, cook together with 4 parts of high-density PE, and the temperature can reach up to 125°C, so that bamboo and potato powder and high-density PE can form a mixed paste;

[0028] (5) Fully ...

Embodiment 3

[0030] A kind of preparation method of easily degradable biofiller is made by the following steps:

[0031] (1) 10 parts of corn stalks are puffed to form a loose, porous and crispy puffed product, which is cut into several uniform small pieces;

[0032] (2) Put 14 parts of shell powder and puffed corn stalks into an airtight container, rotate the airtight container to fully mix the shell powder and corn stalks, and heat the airtight container during the rotation to make the temperature reach 110 °C, after mixing, quickly cool down to 70 °C for use;

[0033] (3) Put the mixture in step (2) into a molding machine to form a uniform mixture. The molding machine can be a granulator or an extruder to form a round or cylindrical mixture;

[0034] (4) Grind 9 parts of bamboo and potato into powder, cook together with 2 parts of high-density PE, and the temperature can reach up to 125°C, so that bamboo and potato powder and high-density PE can form a mixed paste;

Abstract

The invention provides an easy-degrading biological filler preparation method, which comprises: (1) puffing corn straw to form a loose, porous and crispy puffed material, and cutting into a pluralityof uniform small blocks; (2) placing shell powder and the puffed corn straw blocks into a closed container, rotating the closed container to fully mix the shell powder and the corn straw blocks, heating the closed container during the rotating to achieve a temperature of 100-120 DEG C, and rapidly cooling to a temperature of 60-80 DEG C so as to be spare after completing the mixing; (3) placing the mixture obtained in the step (2) in a molding machine, and molding to form a mixture having uniform shape; (4) grinding Maranta arundinacea into powder, and decocting the Maranta arundinacea powderand high-density PE, wherein the temperature can be up to 125 DEG C, such that the Maranta arundinacea powder and the high-density PE can form a mixed paste; and (5) completely mixing the mixed pasteand the mixture, such that the mixed paste is wrapped and infiltrated into the mixture to form the biological filler.

Description

technical field [0001] The invention relates to the technical field of preparation of biological fillers, in particular to a method for preparing easily degradable biological fillers. Background technique [0002] Biological fillers are divided into composite fillers, three-dimensional elastic fillers, porous suspension ball fillers, active biological fillers, etc. In the aerobic biological fluidized bed process, the three-dimensional hollow filler is used as the aerobic biological carrier. The filler is a hollow structure, which is suspended in water during normal operation. Anaerobic bacteria grow inside the filler to produce denitrification to denitrify; aerobic bacteria grow outside to remove organic matter, and there are nitrification and denitrification processes in the whole process. At present, the existing biological fillers all use the overall frame of plastic profiles. Although this frame can allow pollutants to adhere and form a hanging film, it is not easy to d...
