Example Embodiment
[0041] The specific implementation of the technical scheme of the present invention includes three parts: biological enzyme pretreatment of reed extracting black liquor, potash alkali method reed pulping black liquor extraction, and production of finished potassium fulvic acid organic fertilizer:
[0042] 1. Biological enzyme pretreatment of reed extract black liquor
[0043] 1.1 Wet preparation:
[0044] Reeds purchased from farmers are used and transported to a grass cutter to cut into 15-30mm long pieces. After being dusted by a horn dust collector, they are transported by a belt conveyor to a drum washing machine and a hydraulic grass washer before being washed and dehydrated. To the next process.
[0045] 1.2 Biological enzyme pretreatment extracts black liquor from reed:
[0046] The washed and dehydrated reed material prepared by the wet method is transported to the biological enzyme pretreatment bin by a belt conveyor, and the washed reed is subjected to biological enzyme pretr...
