Background technology
Biological organic fertilizer is meant the mikrobe of specific function; With the plant and animal residues material in source, be composited through rotten hot harmless treatment one type, the fertilizer with microbial fertilizer and fertilizer effect; The biological organic fertilizer nutritive element is complete; Can improve the soil, improve the quality of products and quality, and use conveniently.
The preparation method of biological organic fertilizer mainly is a stack retting at present, in physical environment, ferments.Though this method is easy, reduced investment, fermentation condition is wayward, and fermentation is slow, and the production cycle is long, and the [that the stack retting process produces influences surrounding environment with the mosquitos and flies that grows.
Summary of the invention
The objective of the invention is for overcoming the deficiency of prior art, and a kind of method for preparing biological organic fertilizer with fermenter is provided.This method can realize the batch production production of biological organic fertilizer, and with short production cycle, and output is high, and quality is good, and is environmentally friendly.
The technical scheme that realizes the object of the invention is:
A kind of method of utilizing fermenter to prepare biological organic fertilizer comprises the steps:
(1) biological organic fertilizer fermenter of preparation;
(2) batching: main organism 30-40% mixes composition by following mud 60-70% by weight percentage, and other adds useful bacterial classification 2-8 kind;
(3) send into fermenter to the material for preparing, in the environment of sealing negative pressure, ferment;
(4) automatic controlling system heating mechanism, humidification mechanism, turn over and throw aeration mechanism and bacterial classification adds the differential responses stage of mechanism in fermenter, material is heated, humidification, is added bacterial classification, turns over the throwing aeration;
(5) [that fermenter is produced is extracted out with vacuum fan, send into environmental protection equipment and handle, material in reactive tank after fermentation maturity 15-17 hour bio-organic fertilizer.
The described fermenter of step (1) is a sealing cell body that is the long tubular of arch door shape; Mainly by travelling belt be arranged on the sealing canopy that flexibly connects with the travelling belt sealing on the travelling belt and constitute; Cell body is divided into intake zone, fermentation zone, turn over and throw the station and go out Fei Qu, and fermenter also is provided with the heating mechanism, the humidification mechanism that are connected with automatic control system, turn over throwing aeration mechanism and bacterial classification adds mechanism.
The described organism of step (2) is rubbish, agricultural organic waste (fowl, animal manure just, tangerine bar, straw, husk, bagasse, edible fungi residues, fermentation tail product etc.) and the industrial organism (paper mill sludge, system grain waste material, food-processing waste material etc.) after the go-on-go; Said mud is the mud after the municipal sewage treatment.
The biological organic fertilizer of the present invention's preparation is through detecting: loose, the ordorless flavor of fertilizer, no worm's ovum, and nitrogen, phosphorus, potassium total nutrient content are 8.7%, and organic matter is 47.1%, and useful bacterial strain content is 0.2 hundred million strain/grams, meets and be superior to the standard of national biological organic fertilizer.
The advantage of present method is: (1) preparation biological organic fertilizer fermentation time is short, and it is fast to go out fertilizer, and production efficiency is high, can go out product in more than ten hour, and good product quality; (2) material is led by travelling belt and is advanced, and continuously feeding, ferments, goes out fertilizer, suitable batch production production; (3) production process does not have the foul smell discharging, and is environmentally friendly.
Embodiment
With reference to Fig. 1, a kind of method of utilizing fermenter to prepare biological organic fertilizer comprises the steps:
(1) biological organic fertilizer fermenter of preparation; This fermenter is a sealing cell body 1 that is the long tubular of arch door shape; It by travelling belt 2 be arranged on the sealing canopy 3 that flexibly connects with travelling belt 2 sealings on the travelling belt 2 and constitute; Cell body 1 general long 40-60 rice; Be divided into intake zone A, heating fermentation district B in the groove, turn over and throw station C, heat-preservation fermentation district D, turn over and throw the station and go out fertile district E, in the fermentation zone of sealing canopy 3, also be provided with heating mechanism, humidification mechanism, turn over and throw aeration mechanism and bacterial classification adds mechanism;
(2) batching: main organism 30-40% mixes composition by following mud 60-70% by weight percentage, and other adds useful bacterial classification 2-8 kind;
(3) send into fermenter to the material for preparing, under the leading of travelling belt, material fully ferments in the environment of sealing negative pressure;
(4) during the fermentation; Control heating mechanism, humidification mechanism simultaneously, turn over and throw aeration mechanism and bacterial classification adds the differential responses stage of mechanism in fermenter by automatic control system; Material is heated, humidification, added bacterial classification, turns over the throwing aeration; Keep temperature to be controlled at 65-78 ℃, humidity is controlled at 65-78%;
(5) [that fermenter is produced is extracted out with vacuum fan, send into environmental protection equipment and handle, material in reactive tank after fermentation maturity 15-17 hour bio-organic fertilizer.
Technical process of the present invention is: intake zone A → heating fermentation district B → first turns over throwing station C and turns over the quick-fried gas of throwing; Stir to stack in echelon → fermentation reaction speed → enterings second that heat-preservation fermentation district D carries out constant temperature, insulation, oxygen and accelerates probiotics in the material turn over and throw station C and turn over the quick-fried gas of throwing, stir, join temperature, insulation reaction; Detect the reaction effect of material at the fermentation zone back segment after → get into out fertile district E and go out fertilizer, get at last loose fertile stack the storehouse slaking pack after 5-6 days finished product.
