Embodiment 1
[0032] The preparation method of the heavy metal ion adsorbent of the present invention is as follows: the orange peel with a water content of 10% is crushed into 20 mesh particles; Treatment; according to the mass ratio of bacterial liquid: water: orange peel = 1:300:800, mix evenly, then put it into the fermentation room for anaerobic fermentation for 72 hours; dry it at 40°C to make the water content reach 10%. Obtain the heavy metal ion adsorbent, then carry out sealed packaging and sell.
[0033] Among them, the mass ratio of Lactobacillus acidophilus and Thiobacillus ferrooxidans is 1:2; the concentration is 2.9 billion live bacteria per milliliter.
Embodiment 2
[0035] The preparation method of the heavy metal ion adsorbent of the present invention is as follows: the orange peel with a water content of 15% is pulverized into 40-mesh granules; Treatment; according to the mass ratio of bacterial liquid: water: orange peel = 5:400:9000, mix evenly, then put it into the fermentation room for anaerobic fermentation for 100 hours; dry it at 60°C to make the water content reach 15%. Obtain the heavy metal ion adsorbent, then carry out sealed packaging and sell.
[0036] Among them, the mass ratio of Lactobacillus acidophilus and Thiobacillus ferrooxidans is 1:3; the concentration is 2.5 billion live bacteria per milliliter.
Embodiment 3
[0038] The preparation method of the heavy metal ion adsorbent of the present invention is as follows: the orange peel with a water content of 20% is pulverized into 80-mesh granules; Treatment; according to the mass ratio of bacterial liquid: water: orange peel = 10: 500: 1000, mix evenly, then put it into the fermentation room for anaerobic fermentation for 240 hours; dry it at 120°C to make the water content reach 22%. Obtain the heavy metal ion adsorbent, then carry out sealed packaging and sell.
[0039] Wherein, the mass ratio of Lactobacillus acidophilus and Thiobacillus ferrooxidans is 2:2. The concentration is 2.2 billion live bacteria per milliliter.
