Embodiment 1
[0021] 1) Dry and crush the straw until it passes through a 100-mesh sieve, then take 10 g of straw powder, add 40 mL of water, extract at 50°C for 1 hour, then filter, and collect the filtrate and filter residue respectively;
[0022] 2) Concentrate the filtrate obtained in step 1) to half of the original volume, then add the filter residue obtained in step 1), and add NaOH under stirring conditions to adjust the pH of the solution to 9-10 to obtain an alkalized feed solution;
[0023] 3) Highly porous diatoms (pore size 50-100nm) were roasted at 500°C for 1 hour to make them preliminarily activated. After cooling to room temperature, take 30g and add 150mL of alkalized feed solution obtained in step 2), ultrasonicate for 5 minutes and then stand for 2 hours , and then vacuum filtered, and the obtained filter residue was quickly washed with water for 2-3 times, and then microwaved at 500W for 20min;
[0024] 4) Add 10 mL of Bacillus bacteria solution (bacteria content ≥ 10 8...
Embodiment 2
[0027] 1) Dry and crush the straw until it passes through a 100-mesh sieve, then take 10 g of straw powder, add 60 mL of water, extract at 30°C for 1 hour, then filter, and collect the filtrate and filter residue respectively;
[0028] 2) Concentrate the filtrate obtained in step 1) to half of the original volume, then add the filter residue obtained in step 1), and add NaOH under stirring conditions to adjust the pH of the solution to 9-10 to obtain an alkalized feed solution;
[0029] 3) Highly porous diatoms (pore size 50-100nm) were roasted at 600°C for 1 hour to make them preliminarily activated. After cooling to room temperature, take 30g, add 180mL of the alkalized feed solution obtained in step 2), ultrasonicate for 10 minutes, and then stand for 3 hours , and then vacuum-filtered, and the resulting filter residue was quickly washed with water for 2-3 times, and then microwaved at 500W for 60min;
[0030] 4) Add 10 mL of Bacillus bacteria solution (bacteria content ≥ 1...
Embodiment 3
[0033] 1) Dry and crush the straw until it passes through a 100-mesh sieve, then take 10 g of straw powder, add 50 mL of water, extract at 40°C for 1 hour, then filter, and collect the filtrate and filter residue respectively;
[0034] 2) Concentrate the filtrate obtained in step 1) to half of the original volume, then add the filter residue obtained in step 1), and add NaOH under stirring conditions to adjust the pH of the solution to 9-10 to obtain an alkalized feed solution;
[0035] 3) Highly porous diatoms (pore size 50-100nm) were roasted at 500°C for 1 hour to make them preliminarily activated. After cooling to room temperature, take 30g and add 160mL of the alkalized feed solution obtained in step 2), sonicate for 8 minutes and then let it stand for 2 hours , and then vacuum filtered, and the obtained filter residue was washed with water for 2-3 times quickly, and then microwaved at 500W for 30min;
[0036] 4) Add 10 mL of Bacillus bacteria solution (bacteria content ≥...
