Abstract
The invention discloses a method for preparing urea from traditional Chinese medicine residues, and relates to the field of biomass. The method comprises the steps that the traditional Chinese medicine residues are dried, smashed and sieved through a molecular sieve to obtain traditional Chinese medicine residue powder, the traditional Chinese medicine residue powder is transferred into a fermentation tank and inoculated with saccharomycetes for fermentation, and the fermented product is mixed with urea and dried. According to the method, the traditional Chinese medicine residues are used as raw materials, the traditional Chinese medicine residues produce more nutrient in a fermentation mode, then a small amount of urea is added, finally, the organic matter content in soil can be improved, the soil fertility is further improved, and it is ensured that plants are supplied by sufficient nutrient.
Description
Technical field
The present invention relates to living beings technical field, especially a kind of method of utilizing Chinese medicine slag to prepare urea.
Background technology
Chinese medicine slag is as a kind of living beings, the annual emissions of the annual Chinese medicine slag of China reaches 3,000 ten thousand tons, and the processing of Chinese medicine slag often adopts traditional processing method as burning, landfill, FX stacking etc., not only to drop into a large amount of funds, and cause the waste of resource and serious environmental pollution. Therefore, in recent years there is a large amount of scientific research personnel's Study of Traditional Chinese Medicine slags, to widen the range of application of Chinese medicine slag, turn waste into wealth. At present, had scientific research personnel to prepare feed, fertilizer, active carbon etc. with Chinese medicine slag, but the technological means that adopts Chinese medicine slag to prepare urea there is not yet report.
Summary of the invention
The object of this invention is to provide a kind of method of utilizing Chinese medicine slag to prepare urea, this Chinese medicine slag that utilizes
The method of preparing urea provides a kind of regeneration method of new Chinese medicine slag.
The technical scheme that invention adopts is:
This method of utilizing Chinese medicine slag to prepare urea comprises the following steps:
A, by Chinese medicine slag dry, pulverize, cross molecular sieve, obtain Chinese medicine slag powder;
B, described Chinese medicine slag powder is proceeded in fermentation tank to inoculation yeast bacterium, fermentation;
C, by fermentation after product mix with urea, oven dry.
In technique scheme, technical scheme can also be more specifically: saccharomycetic inoculum concentration is 3%～5%, and fermentation temperature is 30 DEG C～35 DEG C, and pH is 4～6, and shaking speed is 300 revs/min～400 revs/min.
Further, the mass ratio of Chinese medicine slag and urea is 1:0.02～0.1.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention, taking Chinese medicine slag as raw material, makes Chinese medicine slag produce more nutrients by the method for fermentation, and then adds a small amount of urea, can improve the content of organic matter in soil, further improves the fertility of soil, has ensured that plant has sufficient nutrient supply.
