Summary: | The invention discloses a preparation method of microbial inoculum-loaded biological activated carbon, which is characterized by comprising the following steps: 1) pretreatment of activated carbon: carrying out dipping pretreatment on the activated carbon by using an acid solution, and then washing and drying; 2) activation of activated carbon: under the protection of nitrogen, raising the temperature to 800-1000 DEG C, and introducing an activating agent to carry out an activation reaction; and (3) preparation of the microbial inoculum-loaded biological activated carbon: putting the activated activated carbon in an open container, putting the container in a dryer capable of vacuumizing, vacuumizing the activated carbon at normal temperature, closing a vacuum pump after vacuumizing for a period of time, adding the liquid microbial inoculum into the activated carbon, and drying to obtain the microbial inoculum-loaded biological activated carbon. The liquid inoculant can quickly enter pores inside the activated |
