A kind of bio-organic fertilizer produced from papermaking sludge and its manufacturing method

Abstract

The invention relates to a microbial organic fertilizer produced by papermaking sludge and a producing method thereof. The producing method is characterized in that the papermaking sludge, calcined lime, ferrous sulfate, magnesium sulfate, peanut cake meals, rice bran powders, waste plants, microbial organic fertilizer quick fermentation strain fungicides, organic matter decomposing inoculants, lysine, ammonium nitrate, monoammonium phosphate, potassium sulfate, triacontanol, sodium nitrophenolate, an organic activating agent and the like are evenly mixed by adopting a double-shaft paddle mixing blender to produce powders or particles produced into a papermaking sludge microbial organic fertilizer product through packaging. The product has the advantages and effects that the nutrition constituents are complete, and various nutrients, such as nitrogen, phosphorus, potassium, various trace elements, organic acids and the like, contained in the product can be used for the growth requirements of crops; no pollution is generated; the cost is low; the benefit is good; the problem of the secondary pollution caused by the papermaking sludge is solved; the environment is protected; the land is also saved and the like.

Description

technical field [0001] The invention relates to a bio-organic fertilizer produced from papermaking sludge. Specifically, it is made of papermaking sludge, which is mechanically dehydrated, subjected to high-temperature fermentation, sterilization, drying, crushing, and screened powder and peanut cake. Bio-organic fertilizer produced mainly from meal, rice bran and waste plants, belongs to the field of waste treatment. [0002] The invention also relates to a method for manufacturing the papermaking sludge bio-organic fertilizer. Background technique [0003] Papermaking sludge is the industrial wastewater produced in the process of producing various papers in the paper mill and the domestic sewage discharged from the living area of ​​the factory. A kind of mixed solid waste obtained from froth, the composition sources of papermaking sludge are relatively complex, which contains a large amount of cadmium, mercury, lead, chromium, arsenic, nickel, zinc, copper, cyanide, pathog...

AI Technical Summary

Problems solved by technology

At present, nearly 80% of the sludge in the country has not been stabilized and harmlessly treated, and most of it is still sent to urban landfills for simple landfill. Every ton of wet sludge with a moisture content of 80% is buried. It will produce a total emission of 0.5 tons of carbon dioxide and emit a large amount of methane to the environment. Its greenhouse effect is dozens of times that of carbon dioxide, so the secondary pollution is serious

The composition of papermaking sludge is relatively complex, with high water content and difficult treatment. A large amount of accumulated sludge will not only occupy a large amount of land, but also harmful components such as heavy metals, pathogenic bacteria, parasite eggs, organic pollutants and odor will be reduced. Become a major hazard affecting urban environmental sanitation

Especially for heavy metals, if they are directly buried without treatment, they will pollute the soil and groundwater sources, easily produce new secondary pollution, and cause serious harm to the environment.
