Description
Technical field
The present invention relates to the high-valued comprehensive utilization of biomass resource and field of environment pollution control, be specifically related to a kind of energy
Enough alleviate the charcoal fertilizer of heavy metal pollution.
Background technology
Whether cereal crops still in the field of planting of industrial crops, the means of fertilising are just used to carry for a long time
High crop yield and quality.From the earliest use farm organic fertilizer to using inorganic fertilizer, then to using compound organic and inorganic fertilizer.Execute
Cereal crops or yield of commercial crops and quality are all had a great impact by fertile kind, dose and proportioning etc..Traditional fertilizer
Although especially compound organic and inorganic fertilizer serves good effect in terms of improving crop yield.But, traditional fertilizer is deposited
Unreasonable at composition and nutrient formula, it is little to recover soil fertility, improve Soil structure, the most also can have side effects,
Cause soil compaction etc..
The survival and development of the mankind are all the time along with substantial amounts of people and the generation of animal residue, along with carrying of people's life
Height, human and animal excreta is the most serious to the pollution of environment.First, containing substantial amounts of organic matter and nitrogen, phosphorus, potassium etc. in human and animal excreta
Material, if directly discharging, can cause water pollution and eutrophication.Secondly, containing a large amount of pathogen in feces, easily cause big
Scale infectious disease popular.Again, fecal sewage produces toxic and harmful after organic decomposition of rotting, stench occurs.This
A little all severe contaminations the earth, water body, air and biome, and to health generation potential threat.Human and animal excreta simultaneously
Mostly have that moisture content is high, be difficult to store, the feature such as perishable of making moist, cause that cost of transportation is big, storage area big and is processed into
The problems such as this height.Therefore seek suitable human and animal excreta processing method and there is realistic meaning and Commercial Prospect.
Charcoal be bio-organic materials (biomass) in anoxia or anoxybiotic environment, after high temperature pyrolysis generate consolidates
State product.Can not only be used for the high-quality energy, soil conditioner, it is possible to seal as reducing agent, fertilizer slow release carrier and carbon dioxide
Deposit agent etc., be widely used to carbon fixation and emission reduction, water source purifying, heavy metal adsorption and soil improvement etc., can be to a certain extent
The hot issue that the whole world such as climate change, environmental pollution and soil function degeneration is deeply concerned provides solution.It is at hypoxia ring
Under border, by Pintsch process, timber, grass, corn stalk or other Wastes of Crops carbonization are formed.Though charcoal can as fertilizer,
But its microcellular structure is less, specific surface area is relatively low, and the nutrient retained includes that trace element is less, general when therefore using
Need to add other fertilizer.
Summary of the invention
It is an object of the invention to provide a kind of charcoal fertilizer that can alleviate heavy metal pollution.
The technical scheme realizing the object of the invention is:
A kind of charcoal fertilizer that can alleviate heavy metal pollution, is made up of the raw material of following weight parts:
Charcoal 60-80, compound fertilizer 10-12, fermentation liquid 10-12, auxiliary agent 6-10.
Described charcoal, is to be mixed according to the ratio that mass ratio is 2:2:1 by corn straw, wheat stalk, rice straw
After conjunction, processing to moisture through dry in the sun is 20-25%, then extruder grain and retort carbonization form.
Described compound fertilizer, is that potash fertilizer, nitrogenous fertilizer, carbamide, calcium hydrogen phosphate are according to the ratio mixing system that mass ratio is 1.5:1:1:1
Become.
Described fermentation liquid, is made up of the raw material of following weight parts: fresh Entermorpha 80-100, peat composed of rotten mosses 20-30, bran coat 10-
20, Fructus Musae corium farinosum 8-10；Its preparation method is: smashs to pieces after being cleaned by fresh Entermorpha and mixes with the peat composed of rotten mosses, bran coat, Fructus Musae corium farinosum,
Putting into the regulation water content that adds water in fermentation vat is 42-44%, then inoculating complex microorganism microbial inoculum in fermented product, afterwards will fermentation
Thing stirs and starts fermentation, every turning in 3-4 days once, and measures fermentation heap temperature simultaneously, controls fermentation heap maximum temperature
Less than 72 DEG C, ferment 24-26 days, after becoming thoroughly decomposed completely, fermentation heap squeeze and filter is obtained fermentation liquid.
Described complex micro organism fungicide includes Rhizopus oryzae, bacillus subtilis and Bacillus cercus, shared mass ratio
For 1:2:2.
Described auxiliary agent, is fusing urea and water mixes according to the ratio that mass ratio is 1:2.
The preparation method of above-mentioned a kind of charcoal fertilizer that can alleviate heavy metal pollution, comprises the steps:
(1) weigh raw material according to described ratio, and by described raw material mix homogeneously, obtain compound；
(2) described compound is sent in cracking apparatus, be warming up to 250-270 DEG C, keep this temperature 12-15min, then exist
It is warming up to 460-470 DEG C in 5min, and keeps this temperature 3-4h, then in 4min, be chilled to 160-180 DEG C, keep this temperature
50-60min, natural cooling, obtain product.
Advantages of the present invention is: charcoal fertilizer of the present invention, is with agricultural crop straw as raw material components, its raw material used
Straw is with low cost, and source is easy to get, and is processed by dehydration deoxygenation and pulverizes the biological powdered carbon of formation, carbonization through high temperature carbonization mode
Effective, carbon content more than 25%, it is effectively increased the carbonization degree of straw, charcoal fertilizer yield rate is high, and application effect is good, and can be passivated
Heavy metal in soil, improves the vigor of soil microorganism；Meanwhile, fusing urea is used to serve as liquid phase as helping during preparation
Agent, can further improve the content of effective fertilizer composition, reduces the content of water so that utilization rate and the fertilizer quality of fertilizer more enter
One step is improved, and can reduce difficulty time prepared by product.And there is bigger specific surface area, improve the organic matter of soil
Content；As low cost non-chemically fertilizer, product of the present invention can be the guarantee in organic agriculture, green agriculture offer yield,
Preparation method is simple, controlled, easily implement, and while effectively having processed human and animal excreta and biomass, has than traditional biological charcoal fertilizer
There are higher absorption property and higher fertilizer efficiency, chemical fertilizer application can be replaced within the specific limits, before there is industrialization promotion
Scape, and significantly economic benefit, environmental benefit and social benefit.
