Sugarcane filter mud fermentation inoculant and sugarcane filter mud fermentation method

Abstract

The invention discloses a sugarcane filter mud fermentation inoculant and a sugarcane filter mud fermentation method. The method comprises: utilizing a sugarcane filter mud leavening agent formed by combining a plurality of compound bacteria of a low-temperature strain, a medium-temperature strain and a high-temperature strain for pretreatment, mixed stacking and fermentation treatment on sugarcane filter mud. Through rapid growth and propagation of sugarcane filter mud, microbial fermentation dominant flora is formed, and the sugarcane filter mud can be rapidly heated to 32-58DEG C, so that the time for heating the sugarcane filter mud to a required fermentation temperature is shortened, the temperature rising speed is increased, the fermentation efficiency is improved, and the microbialfermentation dominant flora is very suitable for growth and propagation on the sugarcane filter mud, normal fermentation can be carried out under the condition of relatively low temperature, and the composting temperature can reach 68DEG C, so that the conversion rate of biological enzymes in the filter mud is increased at the high temperature; and the crop is decomposed, according to the filter mud fermentation inoculant, a variety of strains are matched in a proper proportion so as to reach high temperature rising speed, high activity, long high-temperature time, therefore the fermentation time is short, and complete fermentation is achieved.

Description

technical field [0001] The invention relates to the field of sugarcane filter mud fermentation, in particular to a sugarcane filter mud fermentation bacterial agent and a sugarcane filter mud fermentation method. Background technique [0002] In addition to the main products such as white granulated sugar and brown granulated sugar, the sugar cane sugar factory also produces some waste materials, such as bagasse, waste molasses, filter mud and ground scraps, etc., and the filter mud accounts for 2% of the total crushing. Due to the characteristics of high water content and poor ventilation, filter mud is difficult to dry naturally, and it is very easy to be polluted by bacteria. The polluted filter mud enters the soil and affects the growth of crops; the random stacking, dumping and landfill of filter mud not only It takes up land resources, pollutes the air, and pollutes groundwater sources, making the filter mud a waste that "has no place to put it, and it can't be used". ...
