Decomposed leaven for the treatment and use of industrial waste liquid and waste residue and method for preparing the same

Abstract

The invention relates to a decomposed leaven for industrial organic effluent and debris treatment and process for preparation, wherein the decomposed leaven comprises one or more of cellulose disassembling bacterium, himicellulose disassembling bacterium, protein disassembling bacterium, and amylolyzing bacterium, the bacterial are preferably selected from the following bacterial or their combination, aspergillus niger, viridian, endomycopsis fibuliger, bacillus subtilis, and brewer's yeast. The preparation process of the decomposed leaven comprises two steps of preparing bacterial and formulating leaven.

Description

technical field [0001] The invention relates to a decomposed starter for the treatment and utilization of industrial organic waste liquid and residue and a production method thereof, belonging to the technical field of starter production. The present invention is suitable for occasions that require fast fermentation temperature, short cycle, strong ability to decompose cellulose, hemicellulose, lignin, protein, etc., and high degree of maturity of materials, and is especially suitable for the sugar cane sugar industry for its production process. Comprehensive treatment of waste such as molasses alcohol waste liquid, sugarcane pith, filter mud and other waste liquid waste residues and industrial production of organic fertilizers as a special decomposing starter. Background technique [0002] The comprehensive treatment and utilization of organic waste liquid and residue is an important topic in environmental engineering and resource utilization, es...

Problems solved by technology

[0003] 1. The fermentation process is greatly affected by environmental conditions

Due to the use of natural aerobic bacteria carried in the air, waste liquid and waste residue itself to ferment at high temperature, the strains are poorly targeted, the number of effective bacteria is low, and the material cannot be fermented completely in the direction of the fertilizer, and the strains that can play a role in fermentation and decomposing are limited. , therefore, in the absence of sufficient technological conditions, the materials cannot be fully decomposed and decomposed;

[0004] 2. In order to fully decompose the materials to be treated, the treatment process adopts forced ventilation, multiple batching and ridge turning, and also adds rotten plant residues and soil, so the process is complicated and the fermentation time is long (38-71 days ), high operating costs;

[0005] 3. The temperature of fermentation is slow, there is odor, the content of humic acid is low, and the fertilizer efficiency is poor;

[0006] 4. The microbial community of natural materials will change with the influence of seasons and climates, the fermentation process is unstable, and the product quality is also unstable;

[0007] 5. The production method is to ferment in the fermentation tank, and at the same time, ventilation facilities need to be constructed, so the infrastructure investment is large and the production cost is high;

Therefore, this method is not, and it is impossible to carry out large-scale, economical and effective treatment of sugar factory waste.
