Embodiment 1

[0013] A method for producing organic fertilizer by using papermaking waste liquid and crop stalks, comprising the following steps:

[0014] ①. Mix 900 kg of papermaking waste liquid and 700 kg of 60-mesh straw powder, such as wheat straw, and put them into a steaming ball to heat up, making the pressure reach 5 atmospheres, and keep it for 4 hours. A steaming ball is a commonly used pressure vessel.

[0015] ②. Add 4 kg of concentrated sulfuric acid to the cured straw powder mixture until the mixture reaches neutrality.

[0016] ③. Transfer the neutral mixed material to the fermentation tank, add yeast powder at an amount of 15 kg per cubic meter, and 1 kg of straw decomposing enzyme, mix and stir evenly, and then ferment for 5 days. The used yeast powder and biological cellulolytic enzyme are commonly used products in the field of fermentation engineering. Yeast powder can be enzyme bacteria, which is a beneficial microbial group that can produce a variety of catalytic and...

Embodiment 2

[0023] A method for producing organic fertilizer by using papermaking waste liquid and crop stalks, comprising the following steps:

[0024] ①. Mix 1,100 kg of papermaking waste liquid and 700 kg of 60-mesh straw powder, such as corn stalks, and put them into a steaming ball to heat up to make the pressure reach 8 atmospheres and keep it for 6 hours.

[0025] ②. Add 10 kg of concentrated sulfuric acid to the matured straw powder mixture until the mixture reaches neutrality.

[0026] ③. Biological fermentation, add yeast and enzyme to the neutralized mixture, transfer the neutralized mixed material to the fermentation tank, add yeast powder at an amount of 25 kg per cubic meter, and 2 kg of straw decomposing enzyme. After mixing and stirring evenly, ferment for 7 days.

[0027] 4., phosphating, add 110 kilograms of concentrated phosphoric acid in above-mentioned material, and react 4 hours, this moment, pH value is 3.

[0028] ⑤, ammonification, add 130 kilograms of ammoniaca...

Embodiment 3

[0033] A method for producing organic fertilizer by using papermaking waste liquid and crop stalks, comprising the following steps:

[0034] ①. Mix 1,000 kg of papermaking waste liquid with 700 kg of 60-mesh straw powder, such as other crops or weeds, and put them into a steaming ball to heat up, making the pressure reach 6 atmospheres, and keep it for 5 hours.

[0035] ②. Add 7 kg of concentrated sulfuric acid to the matured straw powder mixture.

[0036] ③. Biological fermentation, add yeast and enzyme to the neutralized mixture, transfer the neutralized mixed material to the fermentation tank, add yeast powder at an amount of 20 kg per cubic meter, and 1.5 kg of straw decomposing enzyme. After mixing and stirring evenly, ferment for 6 days.

[0037] 4., phosphating, add 85 kilograms of concentrated phosphoric acid in above-mentioned material, and react 3 hours, and this moment, pH value is 2.5.

[0038] ⑤, ammonization, add 120 kilograms of ammonia water in the mixed reac...

Abstract

The invention relates to a technology for making an organic fertilizer by using crops straws, and concretely relates to a technology for making the organic fertilizer by using papermaking waste liquid and agricultural straw, which solves the problem of difficult treatment of the papermaking waste liquid in the prior art. The technology comprises the following steps: mixing the papermaking waste liquid and straw powder, heating the materials, steaming while pressuring, neutralizing a slaked mixture by acid, performing biological fermentation, adding yeast and enzyme in the neutralized mixture, performing phosphatization and ammoniation, adding ammoniacal liquor in the materials, performing potassic alteration, and finally drying the product. The organic fertilizer changes a traditional idea by taking mineral matters as effective components, the agricultural straws are taken as a carrier, through technical processes of fermentation, ammoniation and phosphatization, characteristics of the organic fertilizer and an inorganic fertilizer are integrated, the organic matter and humus in the fertilizer can improve soil and avoids soil hardening, the breeding activity of microorganism in soil can be increased, and a granular structure of the soil is increased.

Description

technical field [0001] The invention relates to a technology for making organic fertilizer by using crop stalks, in particular to a method for making organic fertilizer by using papermaking waste liquid and crop stalks. Background technique [0002] At present, the main purpose of the sewage treatment method after papermaking is to separate the pollutants in the water from the water, or to extract some of the substances for reuse. However, due to the extremely complex composition of the sewage, the amount of investment required for treatment is huge. As we all know, some Wastewater from paper mills without sewage treatment capacity is an important cause of pollution of many rivers and land; especially in vast rural areas, this phenomenon is more prominent due to the high cost of sewage treatment and lack of effective supervision. However, a large amount of crop stalks are produced every year in rural areas, and the methods for dealing with these stalks are generally throwing...
