Description
Technical field
The invention belongs to field of garbage disposal, specifically a kind of organic fertilizer production side based on the perishable rubbish in the market of farm produce
Method.
Background technique
Market of farm produce rubbish is one of important sources of municipal refuse, and 95% or more is all dish in the rubbish of the market of farm produce
Root-mustrad leaf and pericarp etc., based on organic principle.At present to the processing of market of farm produce rubbish mainly based on common compost, heap
Fertile method is exactly municipal refuse by being made fertilizer after composting process flow processing, and composting technology is broadly divided into simple compost, good
Oxygen compost and anaerobic composting three classes.The garbage compost technology in China and the industrialization composting technology of developed country still have certain poor
Away from compost treatment rate is not high.The major advantage of composting method be can partially realize recycling, but the disadvantage is that process cycle compared with
Long, treatment effeciency is low and generates stench, and composting production fertilizer efficiency is poor.
For this purpose, the Chinese patent that Patent publication No is CN109053283A discloses a kind of utilization on December 21st, 2018
The method that kitchen garbage prepares organic fertilizer is deoiled-enzymolysis processing-grease separation-fermentation-granulation by sorting broken-filtering
Process can effectively reduce the grease in removal rubbish, and effectively recycle nutritional ingredient, and the good organic fertilizer of fertilizer efficiency is made.But
This kind of perishable easily smelly rubbish of kitchen, market of farm produce rubbish, not enough, and fertilizer efficiency is difficult to control organic fertilizer deodorizing process when in use
System.
Summary of the invention
It is an object of the present invention to drawbacks described above present in the existing market of farm produce garbage processing procedure of solution, provide one kind
Organic fertilizer production method based on the perishable rubbish in the market of farm produce.
The present invention adopts the following technical scheme that:
Based on the Organic fertilizer production method of the perishable rubbish in the market of farm produce, include the following steps:
(1) it cleans, the sundries of organic fertilizer cannot be made in sorting removal rubbish；
(2) rubbish after removal of impurities is subjected to filter-press dehydration, obtains filter residue and filtrate；
(3) Mechanical Crushing is carried out to the filter residue, obtains filter residue fragment；
(4) filter residue fragment is added in filtrate, and auxiliary agent is added simultaneously, the stir process in the case where temperature is 25-40 degrees celsius
At least 1 hour, 2-3 hours are stood, obtains slurries；
(5) composite bacteria agent is added in Xiang Suoshu slurries, ferments, obtains fermentation liquid；
(6) fermentation liquid is concentrated and dried, and control moisture content obtains organic fertilizer in 25%-30%, granulation.
The auxiliary agent includes diatomite, starch plastics, rubbish base-material, weight proportion 5:2-3:1-3.
In above-mentioned technical proposal, rubbish first passes through filters pressing, and the filter residue after filters pressing, crushing effect is more preferable, then by filters pressing
Filtrate and control treatment temperature, can effectively adsorb effective component and peculiar smell in filter residue filtrate by the way that auxiliary agent is added,
And auxiliary agent can become final organic fertilizer component, delay the release of effective component, control fertilizer efficiency.
In above scheme, the starch plastics in auxiliary agent are to carry out chemical modification to starch using chemical reaction, reduce and form sediment
The hydroxyl of powder changes its original structure, its own intermolecular reaction force attenuation can be mutual with other sized molecules
Effect, cooperates with diatomite, rubbish base-material, provides load for the effective component in organic fertilizer, keeps fertilizer efficiency.And starch base
The granulating performance of the addition of plastics, organic fertilizer is more preferable, and grain forming degree is good.
Water content is relatively fewer in the rubbish of the market of farm produce, so directly broken in the prior art, the application first carries out filters pressing,
It is crushed again, it is broken compared to directly, more save the broken time.
Preferably, the composite bacteria agent is mixed by bacillus, lactobacillus plantarum, nitrite bacteria, sulfur bacteria.
Composite bacteria agent in this programme, being capable of decomposing organic matter, additionally it is possible to remove odors.
Further preferably, 16-20 parts of bacillus, 10-15 parts of lactobacillus plantarum, nitrous acid are thin in the composite bacteria agent
1-5 parts of bacterium, 2-5 parts of sulfur bacteria, described part are parts by weight.
Preferably, the water content of filter-press dehydration to filter residue is 60-70% in step (2), the water content of filter residue is controlled, benefit
In subsequent fragmentation procedure.
Preferably, being passed through oxygen while stirring in step (4).
Preferably, guaranteeing solid holdup in 25-30% after filtrate is added in filter residue in step (4).
The rubbish base-material includes one of corncob cellulose, corn husk coat, beans shell or a variety of, these types of rubbish base
Material, is the more rubbish in the market of farm produce, more preferable with the conformability of starch plastics and diatomite in auxiliary agent.
Preferably, the preparation method of the auxiliary agent includes:
S1. rubbish base-material is crushed to 50-150 mesh；
S2. starch plastics melt, and the rubbish base-material of diatomite, crushing is added, and mix, auxiliary agent is made.
Preferably, the size controlling of auxiliary agent is at 0.2-1.0 millimeters.The partial size of auxiliary agent not only influences the absorption of auxiliary agent itself
Effect, and it is also larger on the influence of the granulation performance of organic fertilizer, and excessive, organic fertilizer particles forming degree is poor.
By implementing above-mentioned technical proposal, the present invention has the advantage that: it is provided by the invention a kind of based on agricultural trade city
The Organic fertilizer production method of the perishable rubbish in field, utilizes waste resources, and nutritional ingredient recycling is thorough, obtained organic fertilizer fertilizer efficiency
Good, grain forming degree is good, effective component had good sustained release effect.
