Abstract

The invention provides a microbial organic fertilizer containing modified municipal sludge, and a preparation method thereof. The microbial organic fertilizer comprises bioactive peptides, modified municipal sludge, chicken bones, cottonseed powder, wheat bran, waste molasses, vinyltrimethoxy silane, Scenedesmus acuminatus, polyamine cross-linked cellulose resin, honeysuckle flower extract, auxin, biologic humic acid, earthworm globulin and a composite bacterium agent. The effective quantity of live bacteria in the microbial organic fertilizer prepared in the invention is 0.83-0.96 billion/g, the total nitrogen content is 7-10wt%, the total phosphorus content is 3-5wt%, the total potassium content is 8-11wt%, the content of organic matters is 52.6-53.9wt%, the water content is 2.0-2.5wt%, the particle strength is 10.8-11.5N, and the percentage of contaminating microorganism is 2.1-2.6%; and the microbial organic fertilizer can effectively improve the output of agricultural products and the content of nutrients, and has an insecticidal effect.

Description

technical field [0001] The invention relates to a granular bio-organic fertilizer and a preparation method thereof, in particular to a microbial organic fertilizer containing modified urban sludge and a preparation method thereof, belonging to the field of microbial compound bacterial fertilizers. Background technique [0002] With the substantial improvement of sewage treatment capacity, a large amount of excess sludge generated during the treatment process has attracted more and more attention. Relevant surveys show that about 7 tons of wet sludge (with a moisture content of 85%) is produced for every 10,000 tons of sewage treated. The re-dehydration of these colloidal sludge is extremely difficult and costly. If it is not treated in a harmless manner, it will be discarded arbitrarily and simply landfilled, which will not only easily pollute the air, soil and water sources, but also seriously threaten human health and environmental safety, and the treatment cost after sec...
