A method for large-scale treatment of fermentation filter residue and livestock and poultry manure mixture by using fly maggots

Abstract

The invention provides a method for treating a fermentation filter residue and livestock and poultry manure mixture on a large scale through fly maggots. Livestock and poultry manure and gibberellin fermentation filter residues are mixed to control the pH value and used for large-scale fly maggot breeding. The method includes the following steps that firstly, a base material is prepared, wherein the livestock and poultry manure and the gibberellin fermentation filter residues are mixed to prepare the base material; secondly, the water content of the base material is adjusted; thirdly, fly maggot larvae are inoculated; fourthly, a breeding material is added; fifthly, the fly maggots are used for treating the fermentation filter residues and the livestock and poultry manure; sixthly, the fly maggots are separated; seventhly, organic manure is produced. The method is used for treating the fermentation filter residues and the livestock and poultry manure, the pressure of environment pollution can be relieved, resource utilization cost of the fermentation filter residues and the livestock and poultry manure can be reduced, the treatment difficulty can be lowered, collaborative industrialized treatment of the fermentation filter residues and the livestock and poultry manure is achieved, and economic benefits and social benefits are improved.

Description

technical field [0001] The invention relates to the technical field of fly maggot breeding, in particular to a method for large-scale treatment of a mixture of fermentation filter residue and livestock and poultry manure by using fly maggots. Background technique [0002] Fermentation waste residue is organic waste discharged from industrial production such as enzyme preparations, pharmaceuticals, and food. If it is discharged directly without treatment, it will cause new environmental pollution, and it will also cause serious waste of resources such as proteins that can be reused in waste fermentation waste residue. , the resource utilization of waste fermentation residue has attracted widespread attention. [0003] Gibberellins are a class of high-efficiency plant growth hormones with a diterpene carboxylic acid structure, which can promote cell elongation, accelerate growth and development, promote early maturity, increase yield, and are widely used in agricultural produc...

Problems solved by technology

However, the optimal pH for the growth of fly maggots is 6.2-8.0, and the pH is generally maintained between 3.5-4.5 during the gibberellin fermentation process. After the fermentation, the fermented liquid is separated from the solid residue by plate and frame pressure filtration to obtain the fermented filtrate and fresh Fermentation filter residue, the pH of this kind of fresh fermentation filter residue is often lower than 4.5, it is difficult to be directly used for the conversion and utilization of fly maggots, and the pretreatment by means of alkali adjustment or stacking fermentation not only increases the processing cost and procedures, but also due to fresh fermentation The viscosity of the filter residue is very high, and methods such as single alkali adjustment and mixing with fibrous auxiliary materials such as straw cannot make it fully mixed. However, it takes a long time and a large site for stacking and fermentation, making it difficult to achieve large-scale application and industrialization
