A method of composting medicinal residues

Abstract

The invention discloses a medicine residue composting method. The medicine residue composting method comprises the steps that gentamicin residues and lovastatin residues are mixed according to the mass ratio of 15-1:1, aspergillus terreus FZC3 is added in the mixing process, the preservation number is CGMCC12072, and meanwhile an exogenous nitrogen source is added to regulate the C / N ratio in residue fertilizers; all the components are mixed evenly, and the moisture content of the final mixed pile is 60-65%; and the temperature of the pile is detected, when the temperature of the pile is increased to 50 DEG C, the pile starts to be turned and is turned once every two days, and when the temperature of the pile is decreased to below 50 DEG C, the pile is turned once every four days, and the composting duration is smaller than or equal to 21 days. According to the composting method, the removal rate of antibiotic left in the gentamicin residues is 95% or over, and innocent treatment of the gentamicin residues is achieved; in addition, as for organic fertilizers obtained through the composting method, the humification coefficient reaches 30% or over, detection of all indexes prove that all the indexes meet the national industry standards, and the organic fertilizers are high-quality fertilizers with a good fertilizer effect and can be applied to various kinds of soil and crops.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, in particular to a method for composting medicinal dregs. Background technique [0002] The proper disposal of drug residues in pharmaceutical companies has always been one of the problems that companies must face. For traditional Chinese medicine pharmaceutical companies, since the main components of the extracted drug residues of traditional Chinese medicine are the branches and leaves of Chinese herbal medicines, which basically do not contain toxic components that are difficult to degrade, organic The method of fertilizer is processed; it will not cause serious pollution to the environment. The principle of composting traditional Chinese medicine residues with organic fertilizers is similar to the composting of crop straws, and is relatively easy to operate and easy to think about. However, for some companies producing western medicines, the proper disposal of drug residues is even m...

Problems solved by technology

However, lovastatin is a fermented product, and waste residue is produced during the production process, of which the fermented residue is about 700t per year, containing unconsumed protein, fat, bacterial corpses, cellulose and other substances, almost tasteless, solid, light gray, water soluble After that, it becomes a paste; if the fermentation residue is not transported and disposed of in time, it will stink after being piled up for 1-2 days

Lovastatin refining residue is mainly filter aid and a small amount of unconsumed protein and fat. It is the filter residue after separation and filtration and extracted with solvent. It has a pungent solvent taste. About 350t of lovastatin refining residue is produced every year and mixed with coal for use The boiler is incinerated, but there is still no further treatment method and legal stockpile; therefore, the pharmaceutical company that produces lovastatin has a greater impact on the surrounding environment and the lives of residents
