Method for producing mixed organic fertilizer from filtered mud

Abstract

A method for producing a mixed organic fertilizer from filtered mud comprises the following steps: airing is performed: the filtered mud is aired in the sun, so that moisture in the filtered mud is reduced; drying is performed: the filtered mud is dried by means of a hot air dryer until the content of water is about 10%; EM (effective microorganism) solution culturing is performed: brown sugar water containing 2%-3% of brown sugar is adopted, and an EM stock solution is prepared in the proportion of (50-100):1 for culture; ground bagasse is mixed with the dried filtered mud in the proportion of 1:(8-10); a bagasse and filtered mud mixture is sprayed with an EM solution and composted for fermentation, every 100 parts of the mixture is sprayed with 5-6 parts of the EM solution sufficiently, and the mixture and the EM solution are mixed, stirred uniformly and then composted; after fermentation, nitrogen, phosphorus and potassium inorganic fertilizers are doped into the compost and sufficiently mixed, and the mixture is dried, granulated and bagged. The filtered mud serving as organic matter is used for producing the organic fertilizer, the production cost is reduced, besides, the problem that filtered mud of a sugar factory pollutes the environment after being discharged can be solved, and the method has relatively high environmental benefits and economic benefits.

Description

technical field

[0001] The invention relates to a method for making organic fertilizer, in particular to a method for producing mixed organic fertilizer by filtering mud. Background technique

[0002] Guangxi is a major sugar-producing province, with sugarcane planting and sugar production accounting for more than 60% of the country, making it a veritable sugar-producing province. Sugar mill filter sludge is a waste material unique to sugar production. Typically, 0.15 tons of filter mud is produced for one ton of sucrose. The annual production of nearly 6 million tons of sucrose in the country brings nearly 900,000 tons of filter mud.

[0003] At present, due to the extensive use of inorganic fertilizers, the land has been severely salinized and hardened, resulting in a decline in land fertility and serious soil erosion.

[0004] Organic fertilizer is a chemical fertilizer containing a certain proportion of organic matter, which has long-lasting fertilizer effects, improv...

Examples

Embodiment Construction

[0020] The present invention will be further described below in conjunction with examples and accompanying drawings. It should be noted that the following embodiments are only illustrative, and are not intended to limit the present invention.

[0021] Such as figure 1 As shown, the method for producing mixed organic fertilizer from filter mud of the present invention firstly includes step S1, drying, and placing the filter mud removed from the production workshop in the open sun to dry to reduce the moisture therein. There is a lot of water in the filter mud, but the organic fertilizer requires low water content, so the filter mud must be dried, and direct drying will cause too much energy consumption, so add a drying step, using sunlight and wind to The filter mud is preliminarily dried.

[0022] Step S2, a drying step, using a hot air dryer to dry the filter mud. This step is to speed up the production of organic fertilizers. Natural drying takes time and cannot meet the p...
