Examples
Embodiment 1
[0028] Air-dried the sludge and fungus chaff respectively, put them into a pulverizer and crushed them through a 60-mesh sieve, mixed them according to the proportion of sludge accounting for 50% of the total amount of sludge and fungus chaff, put them into a muffle furnace, and pyrolyzed them at 500°C for 4 hours , to obtain sludge-bacteria chaff composite biochar samples.
[0029] The yield of the biochar sample prepared by the steps of this example is 53.55%; the methylene blue adsorption value is 25.17mg / g; the adsorption rate is 83.90%. figure 1 The SEM image of the biochar sample prepared in this example is provided, and it can be seen from the figure that the biochar presents a regular long tube-like porous structure, and the pore structure is rich, clear and relatively developed.
Embodiment 2
[0031] Air-dried the sludge and fungus chaff respectively, put them into a pulverizer and crushed them through a 60-mesh sieve, mixed them according to the proportion of sludge accounting for 50% of the total amount of sludge and fungus chaff, put them into a muffle furnace, and pyrolyzed them at 600°C for 2 hours , to obtain sludge-bacteria chaff composite biochar samples.
[0032] The yield of the biochar sample prepared by the steps of this example is 53.65%; the methylene blue adsorption value is 23.12mg / g; the adsorption rate is 77.07%. figure 2 The SEM image of the biochar sample prepared in this example is provided. From the figure, it can be seen that the surface of the biochar is relatively rough, with a relatively obvious graininess, a thin sheet structure, a large pore size, and the overall appearance is looser and more wrinkled. many.
Embodiment 3
[0034] Air-dry the sludge and fungus chaff respectively, put them into a pulverizer and crush them through a 60-mesh sieve, mix them evenly according to the proportion that the sludge accounts for 50% of the total amount of sludge and fungus chaff, put them in a muffle furnace, and pyrolyze them at 700°C After 2 hours, the sludge-bacteria chaff composite biochar sample was obtained.
[0035] The yield of the biochar sample prepared by the steps of this example is 51.6%; the methylene blue adsorption value is 22.04mg / g; the adsorption rate is 73.47%. image 3 The SEM image of the biochar sample prepared in this example is provided. It can be seen from the image that the surface of the biochar is very rough, with a relatively obvious grainy feel, and the pores are distributed in disorder, showing an irregular pinhole structure with different sizes.
