Problems solved by technology

[0004] 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;
[0005] 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;
[0006] 3. The temperature of fermentation is slow, there is odor, the content of humic acid is low, and the fertilizer efficiency is poor;
[0007] 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;
[0008] 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.

Abstract

The invention relates to an organic fertilizer mainly composed of sugar factory waste liquid and residue and a decomposed starter and a production method thereof. The organic fertilizer is composed of fermented material and decomposed starter; the components and weight ratio of the fermented material are: 10-82% of molasses alcohol waste liquid or / and ash flushing water, and 18-90% of bagasse or / and filter mud , and the rest is one or more combinations of straw, peat soil, animal manure, inorganic fertilizer, and soil, with a weight of 0-15%; the decomposing starter contains cellulolytic bacteria, hemicellulolytic bacteria, proteolytic bacteria The strain of starch-decomposing bacteria is formed by mixing koji; the weight of the decomposed starter is 0.01% to 2% of the weight of the fermented material; A combination of 2 to 5 types of brewer's yeast. The method comprises the following steps: 1) determining the fermented material for decomposing and fermenting treatment; 2) determining the decomposing starter; 3) stacking and fermenting; 4) removing water; 5) screening and packing. The method has the advantages of effectively solving the comprehensive treatment and effective utilization of sugar factory waste liquid and waste residue, the organic fertilizer has high fertilizer efficiency and is beneficial to crop growth, the method is simple, the cost is low, and the product quality is stable.

Description

technical field [0001] The invention relates to an organic fertilizer mainly composed of sugar factory waste liquid waste residue and decomposed fermentation agent and its production method, which belongs to the technical field of comprehensive treatment and utilization of waste liquid waste residue, and is especially suitable for the comprehensive treatment of sugar industry using sugarcane as raw material Molasses alcohol waste liquid, gray water, bagasse, filter mud, etc. are used to produce organic fertilizers. Background technique [0002] In the sugar production process, it is inevitable to produce a huge amount of molasses alcohol waste liquid, alcohol waste liquid boiler ash water (usually referred to as "ash water") and waste pollutants such as filter mud and bagasse. Only molasses alcohol waste If the liquid is discharged directly without treatment, its harm to the environment is staggering. It has been reported that the total amount of ...
