specific Embodiment approach 1
[0021] Specific embodiment one: In this embodiment, a kind of preparation method of water treatment adsorbent based on composite biomass-based material is carried out according to the following steps: 1. Add biochar to sterile water, mix well, ultrasonic 30-50min, static Place, then separate the colloidal suspension in the upper layer from the bottom residue to obtain the colloidal suspension of biochar;
[0022] 2. Prepare mycelial ball growth medium, then inoculate the Aspergillus niger spore suspension, and then culture in a constant temperature shaking incubator at 28-35°C, 140-160r / min for 24-48h, then add biochar colloidal suspension, continue Cultivate for 24-48 hours, wash with deionized water, and obtain a water treatment adsorbent based on a composite biomass-based material; wherein the volume ratio of the biochar colloidal suspension to the growth medium of mycelium balls is (10-30):100.
[0023] In this embodiment, the microbial strains are inoculated into the nutr...
specific Embodiment approach 2
[0028] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the preparation method of biochar in step 1 is to dry the biomass in an oven for 8-12 hours, then crush the biomass until the particle size is less than 0.1 cm, and put it into a tubular In the furnace, adjust the temperature of the tube furnace to the target temperature of 550-650°C, stay at the target temperature for 1.5-2.5 hours, then cool to room temperature, and then pass through a sieve to obtain biochar. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0029] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the biomass is agricultural waste. Others are the same as in the first or second embodiment.
