Method for treating fermentation filter residue and livestock and poultry manure mixture on large scale through 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 present invention involves the field of flies and maggots breeding technology, which is specifically used to use the large -scale method of flying maggots to treat fermented filtrate and livestock and poultry manure mixture. Background technique [0002] The fermentation waste residue is an organic waste discharged by enzymes, pharmaceuticals, food and other industrial production. Direct emissions will cause new environmental pollution without processed.The use of waste fermentation waste residue has attracted widespread attention. [0003] Gibcitin is a type of high -efficiency plant growth hormone with di -cam carboxylic acid structures, which can promote cell elongation, accelerate growth and development, promote precocity, increase yield, and have a wide range of applications in agricultural production.Gibromycin fermentation residue is a solid residue undercut -filtering in the process of gibberee's production process, including insoluble medium an...

Problems solved by technology

However, the optimum pH for the growth of fly maggots is 6.2-8.0, while the pH during the gibberellin fermentation process is generally maintained between 3.5-4.5. After the fermentation, the fermentation liquid is separated from the solid residue by plate and frame pressure filtration to obtain the fermentation filtrate and fermentation. Filter residue, the pH of this type of fermentation filter residue is often lower than 4.5, and it is difficult to directly use it for the transformation and utilization of fly maggots. Pretreatment by means of alkali adjustment or stacking fermentation not only increases the processing cost and procedures, but also because the fermentation filter residue has a very high viscosity. Large, single alkali adjustment, mixing with fibrous auxiliary materials such as straw, etc. cannot make it fully mixed, and it takes a long time and a large site for stacking and fermentation, making it difficult to achieve large-scale application and industrialization
