Abstract

The invention discloses a method for producing an organic fertilizer by using activated sludge, belonging to the field of biological organic fertilizers and aiming to reduce the pollution of the activated sludge to the environment, change wastes into wealth and produce the organic fertilizer by recycling the activated sludge. The technological method disclosed by the invention comprises the steps of: by utilizing the characteristic that the activated sludge contains rich starch, cellulose, fat, proteins and other substance, comprehensively treating the activated sludge by using biological bacterial liquid and an enzymic preparation, wherein the enzymic preparation contains the components as follows: 30-40% of amylase, 25-35% of cellulase, 20-30% of lipase, and 25-35% of protease; and adding bran and other auxiliaries, fermenting in a solid-state fermentation tank at 60 DEG C for 7 hours, drying and crushing to obtain the organic fertilizer. According to determinations based on national standards on the organic fertilizer of the ministry of agriculture in China, relevant indexes of the produced organic fertilizer are all qualified.

Description

Technical field: [0001] The invention belongs to the field of biological technology, and in particular relates to the joint treatment of activated sludge with biological bacteria liquid and enzyme preparation, and the final preparation of organic fertilizer after solid-state fermentation by microorganisms. Background technique: [0002] At present, with the rapid development of industry and agricultural economy, a large amount of activated sludge is produced in production activities. The unpleasant gas produced by these activated sludge will pollute the environment, and it is also a great waste of resources. waste. Because activated sludge is rich in starch, fat, cellulose and protein, etc., these substances are all organic substances, so it is a pity to treat them as waste. Based on the needs of my country's sustainable economic development, it is urgent to find a reasonable method of treating activated sludge. On the one hand, it can realize the reduction of activated slu...
