[0034] Such as figure 1 As shown, the preparation method of the biomass charcoal ammonia nitrogen treatment material provided by the embodiment of the present invention comprises the following steps:
[0035] S101: Calculated by adding 5-10 g of biomass raw materials per 100 mL of alkali solution, add the biomass raw materials into the alkali solution with a mass fraction of 2 wt % to 8 wt %, stir for 2 to 6 hours at 50 to 80 ° C, and then take out And wash with deionized water to neutral, dry; prepare 1wt% ~ 10wt% NaClO 2 solution, adjust the pH value to 2-4 with an acid solution, and disperse the above dried sample in NaClO 2 Bleach in the solution, stir at 60-85°C for 3-5 hours, then wash with deionized water and ethanol until neutral, dry in an oven at 60-80°C for 4-6 hours to obtain the pretreated sample;
[0036] S102: Take out the sample and place it in HNO with a volume fraction of 0.5% to 5%. 3 (65% ~ 68%) solution, activated in the environment of 60 ~ 90 ℃ for 2 ~...
Embodiment 1
[0045] The preparation method of the biomass charcoal ammonia nitrogen treatment material that the embodiment of the present invention provides comprises the following steps:
[0046] a) Add 5g of biomass raw material per 100mL of alkaline solution, add cyanobacteria into a sodium hydroxide solution with a mass fraction of 5wt%, stir for 2 hours at 50°C, take it out and wash it with deionized water until neutral, and dry it . Prepare 1wt% NaClO 2 solution, adjust the pH value to 2 with hydrochloric acid, and disperse the above dried sample in NaClO 2 Bleach was carried out in the solution, stirred at 60°C for 3 hours, then washed with deionized water and ethanol until neutral, and dried in an oven at 60°C for 4 hours to obtain a pretreated sample.
[0047] b) Take out the sample and place it in 0.5% HNO by volume 3 (65%-68%) solution, activated in an environment of 60° C. for 2 hours, and then cleaned with deionized water and ethanol until neutral. Assuming that 5g of samp...
