preparation example Construction

[0044] The present invention also provides the preparation method of the bio-organic fertilizer utilizing municipal sludge, comprising the steps of:

[0045] a. Preparation of compost: 30-70 parts of urban sludge, 10-40 parts of Eupatorium adenophorum, 10-30 parts of peat, 3-10 parts of waste flue-cured tobacco, 3-10 parts of fungal residue, pulverized coal Mix 0-10 parts of ash and adjust the water content of the mixture to 55-65% to obtain compost;

[0046] b. Inoculation: inoculate the traditional Chinese medicine microbial agent into the culture material, and fully mix the strain and the culture material; the inoculum amount of the traditional Chinese medicine microbial agent is urban sludge, Eupatorium adenophorum, peat, waste flue-cured tobacco, and fungus residue , 0.3-1% of the total weight of fly ash;

[0047] c. Fermentation: Ferment the inoculated compost until the water content of the compost is 18-30%, and the content of active microorganisms in the compost is more...

Abstract

The invention discloses a biological organic fertilizer prepared by a municipal sludge and a preparation method thereof, which belong to the field of biological fertilizers. The technical problem to be solved by the invention is providing the biological organic fertilizer prepared by the municipal sludge and the preparation method thereof. The traditional Chinese medicine bacterium biological organic fertilizer prepared by the municipal sludge is obtained by inoculating a traditional Chinese medicine microorganism bacterium agent on the raw materials and then fermenting the mixed materials, wherein the raw materials comprise the following components in parts by weight: 30-70 parts of municipal sludge, 10-40 parts of Eupatorium adenophorum, 10-30 parts of turf, 3-10 parts of waste flue-cured tobaccos, 3-10 parts of bacterium slag and 0-10 parts of coal ashes. According to the invention, by using the organic fertilizer prepared by inoculating the traditional Chinese medicine bacterium on the raw materials according to an appropriate mixing ratio and then fermenting the mixed materials, the organic matters as well as N, P, K and other matters can be sufficiently utilized; and the heavy metal in the sludge can be passivated to reach the agricultural standard; and the biological organic fertilizer disclosed by the invention has the effects of improving the soil, increasing the fertility, improving the plant root system micro-ecological environment, improving the crop quality, increasing the yield and the like.

Description

technical field [0001] The invention belongs to the field of biological fertilizers, and in particular relates to a biological organic fertilizer prepared from urban sludge and a preparation method thereof. Background technique [0002] Municipal sludge is solid waste produced during the treatment of urban domestic sewage and industrial sewage, and is an inevitable product of sewage treatment plants. With the development of urbanization, the huge amount of sludge has become an important issue for the development of cities in China. The traditional landfill method, incineration method, direct drying method, anaerobic digestion method and other treatment methods not only have high treatment costs but also cause secondary pollution. [0003] Bio-organic fertilizer has the effects of improving soil, increasing fertility, improving the micro-ecological environment of plant roots, improving crop quality, eliminating or reducing pesticide residues, etc. It is an ideal fertilizer f...
