Method for producing well-composted organic raw materials by using sugar refining filter mud and bagasse

Abstract

The invention provides a method for producing well-composted organic raw materials by using sugar refining filter mud and bagasse. The method comprises the steps of blending the sugar refining filter mud, of which the weight ratio is 90.01-99.9%, and the bagasse, of which the weight ratio is 0.1-9.99%, so as to form a filter mud fermentation material, then, putting the filter mud fermentation material in a fermentation tank or stacking the filter mud fermentation material into window shapes on the ground surface, carrying out aerobic fermentation, stirring with fermentation equipment during fermentation, carrying out fermentation composting, and dehydrating, so as to obtain the well-composted organic raw materials. The method provided by the invention can be used for effectively utilizing the sugar refining filter mud and the bagasse and is good in fermentation effect and small in floor area, meanwhile, secondary pollution resulting from bad smell can be avoided, and the aims of high efficiency and environment-friendliness are achieved.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly treatment and resource recycling of sugarcane sugar-making organic waste, and specifically relates to a method for producing decomposed organic raw materials by using sugar-making filter mud and bagasse. 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 1 ton, and the annual production of bagasse after pressing sugar is about 18 million tons, and filter mud is 3 million tons.

Problems solved by technology

At present, various existing technologies basically adopt the common trough type or strip stacking type for direct stacking and retting fermentation in the fermentation process, but they have not achieved ideal results, mainly reflected in: first, it is easy to produce serious odor, resulting in serious The secondary environmental pollution problem does not meet the requirements of environmental protection; the second is that the fermentation efficiency is low and the cycle is too long, usually 50-60 days, or even 70-80 days, and the utilization rate of the site is not high; the third is that the fermentation maturity is not high and the nutrients The conversion is insufficient, the fertilizer efficiency is not good, and the product is not recognized by the market; the fourth is that the production process basically needs to rely on the secondary drying process of drying, and the production cost is high; the fifth is that the production process needs to add a large amount of other dry materials, and It is difficult to guarantee the supply of these dry materials in large quantities, which makes production more difficult

The main reason is that the material has high moisture content and high viscosity, the air permeability in the stockpile is very poor, and a large amount of anaerobic fermentation is carried out in the material, which leads to serious odor during the fermentation process, and the fermentation cycle is very long. In order to obtain a certain output , the fermentation can only be artificially terminated when the fermentation is not completed at all, the maturity of the material is still quite low, and the moisture content is still high. The nutrient conversion is not sufficient, and it needs to rely on secondary drying
