Problems solved by technology

[0003] At present, a large amount of organic sludge produced by industrial and agricultural production in my country is basically disposed of through incineration or direct landfilling. This treatment method has the problems of high cost, large land occupation, and secondary pollution; while the treatment of livestock and poultry manure and comprehensive utilization technologies are relatively backward, which not only causes environmental pollution, but also wastes a large amount of high-quality organic matter

Embodiment 1

[0021] Raw materials:

[0022] Activated sludge refers to sludge with a moisture content of ≤ 80% after biochemical treatment of industrial and domestic sewage;

[0023] Livestock and poultry manure is fresh livestock and poultry manure with a moisture content of 50%-70%;

[0024] Plant ash organic matter is the organic matter obtained from the burning of herbaceous or woody plants.

[0025] Process steps:

[0026] Mix activated sludge, livestock and poultry manure, and plant ash organic matter according to mass percentages of 5%, 90%, and 5%, adjust the humidity to 60%, and ferment after stacking. The height of the pile is 0.8-1.0m. Afterwards, it is covered with plastic film, and the pile temperature reaches 65°C-70°C and turned over once. After 6 days of fermentation, the pile height is 2.0m. After ripening and fermentation for 23 days, it is crushed, screened, quantified, packaged, and put into storage. The technical indicators meet the requirements of the People's Repu...

Embodiment 2

[0028] Raw materials:

[0029] Activated sludge refers to sludge with a moisture content of ≤ 80% after biochemical treatment of industrial and domestic sewage;

[0030] Livestock and poultry manure is fresh livestock and poultry manure with a moisture content of 50%-70%;

[0031] Plant ash organic matter is the organic matter obtained from the burning of herbaceous or woody plants.

[0032] Process steps:

[0033] Mix activated sludge, livestock and poultry manure, and plant ash organic matter according to mass percentages of 10%, 80%, and 10%, adjust the humidity to 70%, and ferment after stacking. The pile height is 1.0-1.2m, and the pile is loose. Afterwards, it is covered with agricultural film, and the pile temperature reaches 65°C-70°C and turned over once. After 7 days of fermentation, the pile height is 2.5m, post-ripening and fermenting for 28 days, crushed, screened, quantified, packaged, and put into storage. The technical indicators meet the requirements of the...

Abstract

The invention discloses a production method of organic fertilizer. The organic fertilizer is prepared from the following raw materials in parts by mass: 5-10% of activated sludge, 80-90% of excrementsof livestocks and 5-10% of plant ash organic matter. After the raw materials are mixed at a ratio, pile fermentation is carried out under a natural condition, and smashing and screening are carried out to obtain the organic fertilizer. The production method of the organic fertilizer has the advantages of rich raw material source, simple production process, low cost and high market competitiveness; the excrements of the livestocks and organic matter sludge can be subjected to harmless and reduction processing to realize the efficient utilization, the recycling and the source reuse of the organic matter; the yield and the quality of crops can be improved, soil is improved, soil fertility is improved, and the production method has an obvious function on environment protection.

Description

technical field [0001] The invention relates to a production method of organic fertilizer. Background technique [0002] China is a large agricultural country, and agricultural production is the basic industry of our country, and a large amount of chemical fertilizers are consumed in agricultural production every year. Due to the irrational use of chemical fertilizers and a large amount of waste residues produced by industrial and agricultural production, serious pollution problems have been caused to the environment. Therefore, the promotion of green organic agricultural products, improvement of soil fertility and quality of agricultural land, and multi-channel research and development and use of organic fertilizers have important practical significance for reducing environmental pollution, protecting the environment, comprehensively utilizing natural organic matter, and ensuring food safety. [0003] At present, a large amount of organic sludge produced by industrial and ...
