Problems solved by technology

However, the degree of industrial application is not very high, and the amount of annual waste is quite large
There are also those who use waste residues to further ferment to obtain biogas. However, the resulting sludge is also difficult to deal with. Untreated sludge is difficult to use in agricultural production, and littering will definitely seriously pollute the environment.

Embodiment 1

[0033] (1) Feeding weight parts of formula:

[0034] 5000 parts of cassava vinasse; 3 parts of 40% sodium hydroxide aqueous solution; 200 parts of chicken manure; 300 parts of pig manure; 100 parts of filter mud from sugar factory; 1 part of Trichoderma reesei; 1 part of high temperature actinomycetes; 1 part of yeast Parts; 3 parts of cassava residue decomposed finished product; 1.5 parts of ferrous sulfate; 1 part of magnesium sulfate.

[0035] (2) Processing method:

[0036] Dilute the 40% sodium hydroxide aqueous solution 1000 times and evenly spray it on the cassava lees to adjust the PH value of 6-8. The cassava residue is fed into a screw press of a dehydration device, and the dehydration is carried out by adjusting the speed, and the water content of the cassava lees after treatment is reduced to 65-75%.

[0037] Add 200 parts of chicken manure, 300 parts of pig manure, 100 parts of sugar factory filter mud to the dehydrated cassava lees, 1 part of Trichoderma reesei, 1 part ...

Embodiment 2

[0039] (1) Feeding weight parts of formula:

[0040] 5000 parts of cassava vinasse; 8 parts of hydrated lime; 300 parts of chicken manure; 1 part of yeast; 0.5 part of Bacillus stearothermophilus; 10 parts of urea; 6 parts of calcium magnesium phosphate fertilizer; 3 parts of potassium chloride; 1 part of zinc sulfate; 0.5 parts of copper.

[0041] (2) Processing method:

[0042] Sprinkle the slaked lime evenly on the cassava lees and adjust the pH to 7.5. The cassava lees is sent into the plate and frame filter press of the dehydration equipment, and the pressure is adjusted for dehydration, and the water content of the cassava lees is reduced to 55-70% after treatment.

[0043] Add cassava vinasse with a water content of 55-65% to 300 parts of chicken manure, 10 parts of urea, 1 part of fermentation inoculant yeast, 0.5 part of Bacillus stearothermophilus, mix the materials evenly with a mixer, and add to the fermentation In the tower, the air is adjusted by the oxygen supply devi...

Embodiment 3

[0045] (1) Feeding weight parts of formula:

[0046] 4000 parts of cassava lees; 1000 parts of cassava distiller's anaerobic digestion; 10 parts of hydrated lime; 1000 parts of crop straw.

[0047] (2) Processing method:

[0048] The slaked lime is uniformly mixed with cassava distiller's lees and cassava distiller's anaerobic digestion biogas residue, and then sent to the crawler filter press of the dehydration equipment for dehydration, and the water content is reduced to 55-65% after treatment.

[0049] Add cassava distiller's lees and cassava distiller's dregs with a moisture content of 65 to 75% and anaerobic digestion biogas residues into crop straws, mix the materials evenly with a mixer, stack them on the ground, level them, and cover them for natural fermentation. The oxygen supply is adjusted by the oxygen supply device to control the temperature at 45-70°C. When the fermentation temperature reaches 65-70°C, the mixing machine is started to mix and dissipate heat, and take a...

Abstract

The invention provides a method for producing products such as organic fertilizers, biological fertilizers, organic-inorganic compound fertilizers, plant breeding nutrient mediums, soil improvement materials and water retention materials by industrial chemical fermentation processing of residues from alcohol and starch processing by using tapioca. By the method, waste pollutants of chicken manure, pig manure, cow manure, sheep manure, sugar-refinery mud and the like are fully used, the comprehensive treatment and the recycling development of various organic resources are realized, and the problems for the technical treatment and the environmental influence of industrialized tapioca residues are effectively solved; and no three-waste emission occurs in the whole treatment process, the secondary pollution is avoided, and good economic benefits and social benefits are generated.

Description

Technical field [0001] The invention belongs to the technical field of organic resource development and utilization and environmental protection, and relates to a method for comprehensive utilization of cassava processing alcohol and starch residues. Background technique [0002] Cassava is one of the important economic crops in the tropics and subtropics. It is cultivated within 30 degrees of the north and south latitudes of the earth and is widely grown in southern my country. Cassava generally contains 40-60% starch, 15-50% cellulose, a small amount of protein, lignin and colloidal substances and other chemical components. It can be eaten directly and is also one of the industrial raw materials, mainly used as raw materials for starch and alcohol production. . However, in the process of industrial production of starch and cassava alcohol, a large amount of cassava residues will be produced. These solid residues mainly contain cellulose and a small amount of lignin, protein a...
