Method for preparing organic fertilizer from sugar filter mud

Abstract

The invention provides a method for preparing an organic fertilizer from sugar mill mud. The method comprises the following steps: blending a certain proportion by weight of sugar mill mud having the moisture content of 60%-80% and a certain proportion by weight of adjusting material having the moisture content of 10%-70% to obtain a mud fermentation material having the moisture content of 50%-75%; next, putting the mud fermentation material on a three-dimensional fermentation apparatus composed of 2-40 layers and 2-40 groups of belt conveyors in the horizontal direction for dynamic aerobic fermentation, and after the mud fermentation material is converted into a decomposed organic material, directly applying the mud fermentation material as an organic fertilizer or an organic raw material for producing organic fertilizer products. According to the method, the sugar mill mud and bagasse can be effectively utilized, the fermentation effect is good, the floor area is small, and meanwhile, secondary pollution generated by stink can be avoided and the purposes of high efficiency and environmental friendliness are achieved.

Description

technical field

[0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a method for preparing organic fertilizers by using sugar filter mud, bagasse and other industrial and agricultural organic wastes to prepare organic fertilizers with high efficiency, energy saving and environmental protection. Background technique

[0002] In the production and processing process of sugarcane sugar enterprises in southern my country, a large amount of organic waste such as bagasse and filter mud will be produced. Among them, the production of bagasse is about 20% of the sugarcane crushed amount, and the filter mud is about 3.5%. According to the data released by the relevant management departments, the annual sugarcane output in several major sugarcane producing areas such as Guangxi, Guangdong, Yunnan and Hainan in southern my country is about 90 million tons, and about 18 million tons of bagasse are produced every year after sugar ext...
