Problems solved by technology

[0002] Papermaking and pulping enterprises will produce a large amount of sludge during production, and these sludges will become a new source of pollution. Therefore, how to deal with these sludges is a difficult problem for papermaking enterprises. The easiest way to deal with these sludges is to use dehydration equipment to After the moisture content of the sludge is reduced to a certain standard or dried naturally, it is sent to the garbage disposal site for landfill. This method becomes a method of waste disposal, which is time-consuming, labor-intensive and unprofitable.

Embodiment 1

[0014] The dry papermaking sludge accounting for 75% of the total amount, the plant straw accounting for 17% of the total amount, and the cottonseed cake accounting for 5% of the total amount are sent to the pulverizer, and then sent to the fermentation tank after being crushed; 1% of the organic fertilizer starter is sent to the fermentation tank, and an appropriate amount of water is added to mix it evenly and then sealed and fermented. Ferment for 18 days in summer and 25 days in winter. The fermentation temperature can reach 45°C. The material is sent to the post-treatment tank; 1% of the total amount of fungicides and 1% of the total amount of compound amino acids are added to the post-treatment tank. papermaking sludge compost; when used, the papermaking sludge compost containing amino acids can be applied as base fertilizer in winter and spring.

Embodiment 2

[0016] The dry papermaking sludge accounting for 76% of the total, the plant straw accounting for 16% of the total, and the cottonseed cake accounting for 5% of the total are sent to the pulverizer, and then sent to the fermentation tank after being crushed; 1% of the organic fertilizer starter is sent to the fermentation tank, and an appropriate amount of water is added to mix it evenly and then sealed and fermented. Ferment for 19 days in summer and 26 days in winter. The fermentation temperature can reach 50°C. The material is sent to the post-treatment tank; 1% of the total amount of fungicides and 1% of the total amount of compound amino acids are added to the post-treatment tank. papermaking sludge compost; when used, the papermaking sludge compost containing amino acids can be applied as base fertilizer in winter and spring.

Embodiment 3

[0018] The dry papermaking sludge accounting for 77% of the total, the plant straw accounting for 15% of the total, and the cottonseed cake accounting for 5% of the total are sent to the pulverizer, and then sent to the fermentation tank after being crushed; 1% of the organic fertilizer starter is sent into the fermentation tank, and an appropriate amount of water is added to mix it evenly and then sealed and fermented. Ferment for 20 days in summer and 27 days in winter. The fermentation temperature can reach 55°C. The material is sent to the post-treatment tank; 1% of the total amount of fungicides and 1% of the total amount of compound amino acids are added to the post-treatment tank. papermaking sludge compost; when used, the papermaking sludge compost containing amino acids can be applied as base fertilizer in winter and spring.

Abstract

The invention discloses paper mill sludge compost with amino acid, and belongs to the field of fertilizer production. The paper mill sludge compost comprises 75%-77% of dry paper mill sludge, 15%-17%of plant straw, 5% of cottonseed cake, 1% of organic fertilizer fermentation agents, 1% of bactericides and 1% of compound amino acid. A method for producing the paper mill sludge compost with the amino acid includes fermentation and mixing. The paper mill sludge compost has the advantages that the method for producing compost with amino acid mainly from paper mill sludge by means of high-temperature fermentation is provided and is low in equipment investment and cost, the paper mill sludge can be harmlessly treated, waste can be turned into wealth, pollution can be abated, the paper mill sludge compost has a good economic benefit, and certain economic benefits and huge social benefits can be generated.

Description

Technical field: [0001] The invention belongs to the field of fertilizers, in particular to amino acid-containing compost produced from papermaking sludge. Background technique: [0002] Papermaking and pulping enterprises produce a large amount of sludge during production, which becomes a new source of pollution. Therefore, how to deal with these sludges is a difficult problem for papermaking enterprises. The easiest way to deal with these sludges is to use dehydration equipment to After the moisture content of the sludge is reduced to a certain standard or dried naturally, it is sent to the garbage disposal site for landfill. This method becomes a waste treatment method, which is time-consuming and labor-intensive and has no profit. After measuring the composition of papermaking sludge, it was found that papermaking sludge belongs to biological solid waste, which not only contains a large amount of cellulose organic matter and plant nutrients such as nitrogen, phosphorus, ...
