Technical field
The present invention relates to a kind of preparation method of soil conditioner, specifically a kind of marine products processing residue and human faecal mass
The method for preparing soil conditioner.
Background technique
The one kind of biomass garbage as solid refuse, is the environmental contaminants that people must deal carefully with, if at processing
It is improper to set, it will leads to serious environmental pollution.Biomass garbage has Regional Water Environment, atmosphere and soil environment etc. potential
Threat.A large amount of foul gas that degradable biomass garbage generates under the conditions of accumulation are also the important of its ambient air quality
One of influence factor；The random stacking of biomass garbage will also result in serious Soil Environmental Pollution, the ingredient of biomass garbage
Sufficiently complex, if feces of livestock and poultry contains a large amount of pathogenic microorganism or helminth, some industrial bio matter rubbish contain acid or again
Containing heavy metals such as gas chromatography and Cu, Cr, Zn in metal, municipal sludge, these contain the biomass rubbish of multiple pollutant
If rubbish is untreated just to be stacked or filled will cause serious pollution to soil environment.
1, marine products processing residue yield is huge, causes serious pollution；
2, world's aquatic products 85% originate from ocean；
3, China is an ocean big country, and for marine product per year over 10000000 tons, generating processing waste can reach 6,000,000
Ton.
The shortage of comprehensive processing and utilization technology, these marine products byproducts are low value-added mainly for the production of feed, fertilizer etc.
Product, or even part are directly abandoned as waste, so not only waste of resource, but also will cause offshore, coastal environments.
Summary of the invention
The purpose of the present invention is to provide a kind of method that marine products processing residue and human faecal mass prepare soil conditioner,
To solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
A kind of method that marine products processing residue and human faecal mass prepare soil conditioner, comprising the following steps:
Step 1: pretreatment: carrying out normal pressure first with raw material of the boiler to acquisition and boil processing, remove the residual of its surface
Meat and sundries, then chemical industry stirred reactor is used, remove marine products processing residue surface lipids class and protein-based impurity；
Step 2: drying: normal diet dryer carries out drying and processing；
Step 3: crushing: carrying out pulverization process to the material after drying using technical grade skeleton breaking machine；
Step 4: continuous carbonization is modified:
1) prepared by low grade products: carbonization treatment is carried out to smashed material using continous way closing high temperature carbonization furnace, this
When obtained product be low grade products；
2) prepared by expensive goods: in conjunction with the practical pollution condition and reparation demand of soil at this stage, adding in carbonation stage
Efficient soil remediation material Zero-valent Iron, prepares middle level products；
3) prepared by expensive goods: for the utmostly society of development, environment and economic benefit, in middle level products
Organic compound fertilizer is added, expensive goods is made into.
Step 5: being granulated, packaging: being granulated and packed using fertilizer granulator, be finally packaged and obtain finished product.
As a further solution of the present invention: in step 1, using 5% hydroxide when removing the residual meat and sundries on its surface
Sodium solution soaked overnight.
As a further solution of the present invention: in step 2, the temperature of drying and processing is 120 DEG C, drying time 2h.
As a further solution of the present invention: in step 3, grain diameter is 40~100 mesh after processing.
As a further solution of the present invention: in step 4, when preparing low grade products, when carbonization treatment its
Carbonization temperature is 600 DEG C, and the time of carbonization is 1h.
As a further solution of the present invention: in step 4, low grade products is black powder.
As further scheme of the invention: in step 4, when preparing middle level products, Zero-valent Iron is loaded in carbonisation
To bone black surface, main component is organic carbon, bone black and Zero-valent Iron.
Compared with prior art, the beneficial effects of the present invention are:
1, Zero-valent Iron loads to bone black surface in carbonisation, greatly improves the adsorption effect of bone black, it is main at this time
Ingredient is organic carbon, bone black and Zero-valent Iron, it not only has heavy metal repairing effect, but also there are also ecology conditioning and is promoted organic
The effect of matter.
2, gained soil conditioner integrates the multiple of reparation, soil ecology conditioning, promotion organic matter and soil enrichment
Repairing effect.
3, the production line of every grade of product is not interfere with each other, can be according to the ratio of the high, medium and low product of market demand flexible modulation
Example.
Detailed description of the invention
Fig. 1 is the flow chart for the method that marine products processing residue and human faecal mass prepare soil conditioner.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Referring to Fig. 1, a kind of method that marine products processing residue and human faecal mass prepare soil conditioner, including following step
It is rapid:
Step 1: pretreatment: carrying out normal pressure first with raw material of the boiler to acquisition and boil processing, remove the residual of its surface
Meat and sundries, then chemical industry stirred reactor is used, it is soaked when removing the residual meat and sundries on its surface using 5% sodium hydroxide solution
Bubble overnight, removes marine products processing residue surface lipids class and protein-based impurity；
