Description

A kind of is the manufacture method of refined organic fertilizer material afforestation garbage conversion

Technical field

The present invention relates to the preparation of a kind of organic fertilizer, particularly relate to a kind of method of the fertilizer adopting afforestation rubbish to make.

Background technology

Current, China city process afforestation waste disposal method is mainly banked up, landfill or burning.The method of banking up is the simplest treatment process, and this method not only takies a large amount of land resources, and fallen leaves, withered grass etc. are rotted gradually in the process of banking up, and attracts mosquito, produces stench, affects the healthy of surrounding resident.Although the application of landfill method solves the problem of land seizure and stench, but due to fallen leaves, withered grass volume is fluffy, burial biodegradation slow, occupy landfill yard landfill space, lower the effective treatment capacity of landfill yard, and the refuse landfill in many cities closely excludes afforestation rubbish.Burning method is object fallen leaves, withered grass etc. being reached minimizing by burning, and the ashes after burning are used as fertilizer.Although ashes are used as fertilizer by this incinerating method, pollutant atmosphere, affects people healthy.The organic fertilizer raw material of urban landscaping rubbish inherently a kind of preciousness, containing a large amount of plant nutrients, as Mierocrystalline cellulose, hemicellulose, lipid material etc., after compost treatment, content and the validity of the main nutrient elements such as its Dan, Pity, potassium and micro-nutritive element promote all greatly.Afforestation rubbish, by compost treatment, is converted into fertilizer, can be applied in urban afforestation, flowers and nursery stock production fertile.Such as: for improving market green soil organic content, greening crop fertilization, flowers and trees maintenance fertilizer etc.The excessive use of current chemical fertilizer, causes the global ecotope difficult problem such as soil quality decline, widespread pollution from the overuse of fertilizers and pesticides in rural area.Soil with organic matter, containing quantity not sufficient, causes soil quality situation continuous decrease, the continuous generation of the phenomenons such as air permeability variation, soil microbial activities reduction, and improving the soil organism is the unique method solving this difficult problem.

Bamboo leachate is the condensate recovery liquid of bamboo wood pyrolysis component in bamboo carbon production process, in faint yellow to sorrel, in acid, containing nearly 200 Multiple components such as organic acid, phenols, ketone, aldehydes, alcohols and heterocyclic, it is wherein main component with acetic acid, account for about 50% of organic composition, this product has the feature of with low cost, easy acquisition.Bamboo leachate is agriculturally widely used, and all has application at reodorant raw material, alkaline land improving and pesticide material.Meanwhile, the bamboo leachate by fermentation after process obviously can promote the degradation capability of microorganism, reduces the discharge of composting process foul gas, strengthens the fertilizer efficiency of composting production, activating soil urase and peroxidase, promote plant growth.

At present, afforestation rubbish is due to containing hard-degraded substances such as a large amount of xylogen, Mierocrystalline celluloses, and the Traditional compost mode cycle is long, efficiency is low, and finished product fertilizer efficiency is not high, and in fermenting process, the release of the foul gas such as ammonia and hydrogen sulfide can cause serious environmental pollution; Therefore, in the urgent need to seeking efficient compost preparation with the shortening cycle, reducing foul gas and producing, improving compost quality.

Summary of the invention

For improving the degradation speed of afforestation rubbish and reducing foul gas generation, the invention provides a kind of fertilizer manufacture method, this fertilizer manufacture method is efficient and convenient, no foul smell, products obtained therefrom fertilizer efficiency are obvious, utilization ratio advantages of higher.

The technical solution adopted for the present invention to solve the technical problems is:

Formula of the present invention is (composition by mass percentage): afforestation rubbish (85 ~ 90%), urea (1.5 ~ 3%), bamboo leachate (0.7 ~ 1.5%), dry hydrate (0.02 ~ 0.05%) corn flour (3 ~ 4%), wheat bran (4 ~ 7%), organic fertilizer fermentation special bacteria agent (0.02 ~ 0.05%).

Its preparation method is as follows.

(1) material pre-treatment: sub-elect the following branch of diameter 2.0cm, leaf and flowers and plants deformed limb from urban landscaping rubbish, and the green garbage sub-elected is carried out fragmentation, size controlling is between 0.5 ~ 2.0cm.

(2) mixing regulates material: add urea and regulate C/N ratio in (20 ~ 30): 1, then add dry hydrate, corn flour and wheat bran successively, control water content between 50% ~ 60%.

(3) ferment: the material regulated is carried out the fermentation of heap body, first bamboo leachate is diluted 500 times, average mark is added into heap body three times, roughly adds once every 8 ~ 10d; After usual 3 ~ 5 days, heap temperature rises to 55 DEG C ~ 60 DEG C, starts turning, turns over once pile every 2 ~ 3d, and heap body remains on more than one week in high temperature (more than 55 ~ 65 DEG C) stage; Treat that temperature reduces to less than 45 DEG C, and after maintaining 10 ~ 15 days, at this moment piling body particle diminishes in cotton-shaped, quality is loosened and is not pricked the hand, and without special odor, color is Vandyke brown, without mosquitos and flies around, meet typical matured compost outward appearance, in conjunction with the detected result of the indexs such as humify index, organic content change, can determine that fermentation completes.

(4) pulverize, sieve: the fertilizer fermented, carry out air-dry to water ratio lower than 30%, then pulverize, sieve (aperture is 5.0mm), namely screen underflow obtains refined organic fertilizer powder (particle diameter≤5.0mm), and the coarse fodder (particle diameter > 5.0mm) after screening can be back in the compost mixture of lower batch.

(5) granulation processing: as required, the organic fertilizer powder that the 4th step obtains can be crushed to particle diameter about 1mm further, adds N, P, K fertile, carries out granulation processing, make organic and inorganic fertilizer material.

(6) finished product packing: undertaken packed by the fertilizer be processed into, packaging completes, storage at normal temperature.
