Embodiment 1
[0060] Utilize rice straw as raw material papermaking waste liquid to extract silicon-containing fertilizer, water preparation, it is to constitute by following weight and number ratio, and it comprises:
[0061] Soluble silicon 0.5;
[0062] Humic acid 0.8;
[0063] Fulvic acid 0.5;
[0064] Cellulose 0.5;
[0065] Phosphorus, potassium, calcium, boron, magnesium 0.3;
[0066] Surfactant -- Thione 0.7;
[0067] Synergist - sodium nitrophenolate 0.7;
[0068] Film former 1;
[0069] water 95.
[0070] Its production process is:
[0071] First take the waste liquid produced by papermaking with rice straw as raw material, then precipitate, filter, measure, add it to the reaction kettle, heat it to 50°C, start the vacuum pump, the vacuum value is -1 atmosphere, carry out secondary pressure distillation and dehydration, control dehydration 60 % is the end point of dehydration; extract 0.5 tons of soluble silicon; 0.8 tons of humic acid; 0.5 tons of fulvic acid; 0.5 tons of...

[0075] Humic acid 4;
[0076] Fulvic acid 3
[0077] Cellulose 3;
[0078] Phosphorus, Potassium, Calcium, Boron, Magnesium 10;
[0079] Surfactant 1;
[0080] Synergist 1;
[0081] Film former 2;
[0082] fly ash 74.
[0083] Its production process is:
[0084] First take the waste liquid produced by papermaking with rice straw as raw material, then precipitate, filter, measure, add it to the reaction kettle, heat it to 60°C, start the vacuum pump, the vacuum value is -1 atmosphere, carry out sub-pressure distillation and dehydration, control dehydration 75 % is the end point of dehydration; stop the vacuum pump, open the discharge valve, release the dehydrated material while it is hot, and then put the material into the drying equipment for drying ...
