[0019] Example 1:
[0020] The production method of spherical activated carbon of the present invention comprises the following steps:
[0021] (1) Mix 100g of glucose, 1g of rhamnolipid, 5g of cetyltrimethylammonium bromide, 10g of humic acid and 1000g, and ultrasonically react at 30°C for 0.5h to dissolve the glucose and mix all the raw materials evenly. Then transfer it into a hydrothermal synthesis kettle, and conduct a hydrothermal reaction at 160 ° C for 18 h. After the reaction is completed, filter and wash the precipitated product to obtain hydrothermal carbon balls;
[0022] (2) raising the hydrothermal carbon balls obtained in step (1) to 500°C at a heating rate of 12°C / min under nitrogen protection, keeping the temperature for 15h, and naturally cooling to room temperature to obtain carbonized carbon balls;
[0023] (3) mixing the carbonized carbon balls obtained in step (2) with sodium hydroxide in a mass ratio of 1:2, raising the temperature to 850°C with a heat...

[0024] Example 2:
[0025] The production method of spherical activated carbon of the present invention comprises the following steps:
[0026] (1) Mix 110g of glucose, 1g of rhamnolipid, 4g of cetyltrimethylammonium bromide, 11g of humic acid and 1000g, and ultrasonically react at 28°C for 1h to dissolve the glucose and mix all the raw materials evenly . It was then transferred to a hydrothermal synthesis kettle, and the hydrothermal reaction was carried out at 180 °C for 18 hours. After the reaction was completed, the precipitated product was filtered, and the precipitated product was washed to obtain hydrothermal carbon balls;
