Abstract
The invention provides a method f or preparing soil organic fertilizer by mixing salty mud and sludge. The method comprises the following steps: (1) pretreating sludge with an organic fertilizer mixing mill, and adding a proper amount of salty mud and plant fiber waste in the mixing process; (2) performing stacking, oxygen enriching and fermenting on the sludge which is subjected to mixing pretreatment; (3) feeding the sludge which is subjected to oxygen enriching and fermenting treatment into an industrial joint production process, including microwave drying, ultraviolet sterilizing, mechanical grinding, mixing and stirring and granulating; and (4) quantitatively packaging the sludge treated in the step (3) to obtain the product. By adopting the method, salty mud combined with alkalinity regulating performance and adhesion performance is adopted, so that the cost is low, the activity of certain heavy metal elements possibly existing in the sludge can be passivated, the heavy metal elements cannot be absorbed by crops, and thus the pollution problem of agriculture can be solved. Furthermore, the product adopted as a base material is mixed with a small amount of inorganic nitrogen, phosphorus and potassium nutrients to produce the soil organic compound fertilizer to greatly promote pollution-free food development in China.
Description
Technical field
The invention belongs to field of environment engineering technology, a kind of method being blended soil organic fertilizer in particular to brine sludge, mud.
Background technology
Brine sludge is a kind of industrial solid wastes.In chlorine industry, the mud discharged during producing chlorine, hydrogen and Caustic soda with Sal for primary raw material electrolytic method, it is mainly composed of magnesium hydroxide, calcium carbonate, barium sulfate and silt particle.The brine sludge using hydrargyrum method to produce contains the compound of hydrargyrum, and mercurous brine sludge enters environment, and meeting contaminated soil and water body, its disposal is a great society difficult problem.
The big problem that the process of city sludge is the most global, the existing decades of research application history of developed country.China's starting is late, but along with industrial development and the raising of the level of urbanization, the treating capacity of sewage sludge and handling rate are progressively improving, and existing total amount has reached millions of ton.At present, countries in the world the major way of sludge treatment is had landfill, burn, throw extra large and agricultural.Owing to landfill needs take a large amount of soil, easily cause secondary pollution, and transport and place cost of erection high, therefore drawback is many.Though burning and can reach minimizing and process, but secondary pollution being serious, and equally exist investment and the high problem of operating cost.Though throwing, sea processes the most simply, expense also saves, but big to environmental destruction, and various countries forbid one after another, just promise to undertake, the disposal of industrial wastes the most at sea, sewage and mud at the beginning of the Chinese government 1994.Therefore, the agricultural use of sewage sludge is the processing mode having most development potentiality.
Summary of the invention
The present invention is to provide a kind of brine sludge, method that mud is blended soil organic fertilizer, its main purpose is the problems referred to above overcoming prior art to exist.
The present invention adopts the following technical scheme that and is achieved:
A kind of brine sludge, mud are blended the method for soil organic fertilizer, it is characterised in that: comprise the following steps:
1) mud is through fertilizer mixing roll pretreatment, adds appropriate brine sludge and waste plant fiber at mixing process；
2) mixing pretreated mud is carried out the oxygen enrichment fermentation of stacking again；
3) mud after oxygen enrichment fermentation process is entered industrialization linkage production procedure, including microwave drying, ultraviolet-sterilization, machine pulverizing, mix and blend and pelletize；
4) will be through step 3) process after mud quantitative package product.
Further, described brine sludge is from chlor-alkali plant institute salt discharge mud, and described mud system derives from various industry and the sewage of life discharge, the filtering residue after nitration denitrification processes.
Further, the oxygen enrichment fermentation of described stacking refers to be layered stacking fermentation, need to be furnished with ventilation duct at the position, three, upper, middle and lower of buttress heap, the supporting oxygen enrichment installation for fermenting of movable type provide oxygen supply.
Further, the oxygen enrichment fermentation of described stacking, its buttress heap time is 2-3 days, and stacking temperature is more than 70 DEG C, to close down various pathogen, the harmful substance such as parasitic ovum, weed seed.
Further, described waste plant fiber uses the fibre rich matter plants such as rice husk, straw, waste mushroom stick, Pericarppium arachidis hypogaeae, tobacco rod.
Further, described microwave drying refers to that the microwave utilizing microwave dryer to produce directly acts on molecule and is converted into heat energy, and the internal-external temperature difference of material is little, homogeneous heating, makes dry mass be greatly improved.
Further, described ultraviolet-sterilization refers to that the ultraviolet germicidal lamp that radiant intensity is 30000uw/c utilizes ultraviolet damage microflora organisms cell, causes growth cell death and (or) regenerative cell dead, reaches the effect of sterilizing.
From the above-mentioned description of this invention, compared to the prior art, present invention have the advantage that
1, the present invention uses the brine sludge with the unification of both regulation alkalescence and adhesive property, the most with low cost but also can be passivated the activity of some heavy metal element that may be present in mud, and is not absorbed by crops, solves agricultural self-pollution problem.Additionally, for coordinating country to carry forward vigorously the development of pollution-free food, using this product is base material, after a small amount of inorganic nitrogen of mixture, phosphorus, potassium nutrition, the agricultural production material that this market capacity of soil mixed organic manure is the biggest can be produced.By above-mentioned industrialization linkage production procedure, its fertilizer leading indicator produced is: the content of organic matter > 35%, nitrogen, phosphorus pentoxide, potassium oxide total amount are not less than 11%, PH=7～8, moisture content (free water) 10-20%, mode of appearance coarse.Use the solution of the present invention to turn waste into wealth, eliminate secondary environmental pollution, it is achieved brine sludge, recycling sludge recycle, the fertilizer produced compared with poultry Excreta, its not only production procedure simple, and production cost is greatly lowered, and makes product more competitive and commercialization.The soil organic fertilizer wide adaptability being made up of product of the present invention, except crops (cereal crops, industrial crops, fruit tree etc.) beyond, forest land, Garden Greenland, road engineering, flowers etc. use this product, can promote the speed of growth and improve its ornamental quality and be difficult to constitute the contamination hazard of food chain, this product to sand loam soil and acid ground, has the effect substantially improveing Soil structure simultaneously.
2, utilize novel microwave drying mode, make dry mass be greatly improved.Microwave drying has that dry rate is big, energy-conservation, production efficiency is high, uniform drying, cleaning produce, easily realize Automated condtrol and improve the advantages such as product quality.
3, the ultraviolet germicidal lamp sterilization using radiant intensity to be 30000uw/c, after antibacterial absorbs ultraviolet, causes DNA to rupture, the crosslinking causing nucleic acid and albumen ruptures, and kills the biological activity of nucleic acid, causes bacterial death, further ensure that various pathogen, parasitic ovum, the killing of weed seed.
