Embodiment 1
[0030] A method for modifying sludge ceramsite that enhances the performance of adsorbing formaldehyde, comprising the following steps: using refractory activated sludge and clay from sewage treatment plants as raw materials, mixing them in a ratio of 1:1, and heating them at a high temperature of 1250°C Calcining to make sludge ceramsite, and then pulverizing the fired sludge ceramsite through a 2mm sieve to prepare dry sludge ceramsite; adding sludge ceramsite to potassium permanganate solution, wherein, the The mass volume ratio of dry sludge ceramsite to potassium permanganate solution is 3:20, and the concentration of potassium permanganate solution is 20g L -1 . Immerse in an oven at 45°C for 18 hours, then let it stand for 30 minutes and filter, then put the filter material in an oven, dry it at 105°C, transfer it to a muffle furnace, and roast it at 450°C for 2 hours to obtain a manganese-loaded modified sex ceramsite.
Embodiment 2
[0032] A method for modifying sludge ceramsite that enhances the performance of adsorbing formaldehyde, comprising the following steps: mixing activated sludge that is difficult to treat in a sewage treatment plant with clay, wherein the mass ratio of activated sludge to clay is 1:2, and the Calcined at 1200°C to make sludge ceramsite, and then crush the fired sludge ceramsite through a 3mm sieve to prepare dry sludge ceramsite; add sludge ceramsite to potassium permanganate solution , wherein, the mass volume ratio of described dry sludge ceramsite and potassium permanganate solution is 1:10, and the concentration of potassium permanganate solution is 10g L -1 . Immerse in an oven at 40°C for 8 hours, then let it stand for 45 minutes and filter, then put the filter material in an oven, dry it at 100°C, transfer it to a muffle furnace, and roast it at 440°C for 2.5 hours to obtain loaded manganese Modified ceramsite.
Embodiment 3
[0034] A method for modifying sludge ceramsite that enhances the performance of adsorbing formaldehyde, comprising the following steps: mixing activated sludge that is difficult to treat in a sewage treatment plant with clay, wherein the mass ratio of activated sludge to clay is 3:2. Calcined at 1300°C to make sludge ceramsite, and then crush the fired sludge ceramsite through a 1mm sieve to prepare dry sludge ceramsite; add sludge ceramsite to potassium permanganate solution , wherein, the mass volume ratio of described dry sludge ceramsite and potassium permanganate solution is 2.2:20, and the concentration of potassium permanganate solution is 5g L -1 . Immerse in an oven at 50°C for 12 hours, then let it stand for 15 minutes and filter, then put the filter material in an oven, dry it at 110°C, transfer it to a muffle furnace, and roast it at 460°C for 1.5h to obtain loaded manganese Modified ceramsite.
