Method for preparing novel biological fertilizer from processing waste of feather

Abstract

The invention discloses a method for preparing a feather-processing residue novel biological organic fertilizer and the steps include: (1) the feather-processing residue is taken as the main raw material, and beneficial organisms flora and water are added; (2) the mixed material is stirred and hermetically fermented; (3) quality is controlled; (4) deodorization is carried out; (5) drying is carried out; (6) the fertilizer is formed and packed The method is characterized in that in the hermetical circumstance, the feather dusts rich in solid proteins are fermented and decomposed in the artificially added beneficial organisms flora, and the fermentation process kills pernicious bacteria and ascarid eggs by utilizing the interaction among bacteria to prepare the novel biological organic fertilizer with a plurality of beneficial flora. The novel biological organic fertilizer thus prepared contains abundant organic matters, beneficial flora and secondary and micro-nutrients, and can, after being applied, effectively improve the structure of soils, enhance the fertilizer conserving capacity and the water retaining capacity of soils, facilitate the releasing of the indissoluble nutrients of soils, improve the feeder capability of soils, adjust (buffer) the PH value of soils and improve the adaptability of soils.

Description

Preparation method of novel bio-organic fertilizer from feather processing waste technical field The invention relates to the field of organic fertilizers, in particular to a novel bio-organic fertilizer technology using feather processing waste as the main raw material. Background technique While feather processing brings economic benefits to enterprises, it also causes social environmental pollution. For example, the down processing enterprises in Wuchuan City, which were awarded the "Hometown of Down and Down in China" by the Ministry of Light Industry of China and the China Down Light Industry Association, produce tens of thousands of tons of waste (mainly feather dust) in the production process every year. The waste from feather processing (mainly feather dust) not only contains a large amount of organic matter, but also contains a certain amount of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, zinc, manganese, molybdenum and other medium and trace elem...
