Abstract
The invention relates to a method for producing an organic granular compound fertilizer from domestic garbage; the method includes crude screening, magnetic separation, crushing, sieving, batching, mixing, and granulating; the method is characterized in that before crude screening, firstly, the domestic garbage is transported into a drying device, and then is subjected to dry steaming, deodorization and sterilization treatment; the method has the advantages of full decay, no pollution, low manufacturing technical requirements, easy operation, mature technology and other advantages; and the prepared compound fertilizer is low in preparation cost and high in fertilizer efficiency, has many organic matters, trace elements and nutrients, and has relatively high practical promotion value.
Description
Technical field
The present invention relates to a kind of method producing compoiste fertilizer, produce a kind of method of organic granular compound fertilizer in particular with house refuse.
Background technology
Every day is toppled over substantial amounts of rubbish in city or cities and towns, and these rubbish had both occupied substantial amounts of soil, and severe contamination the environment of human survival again, and this phenomenon is also increasing along with being continuously increased of population.The method of existing process rubbish, in addition to incinerator burns or buries and fills out mountain valley lowland, also has and house refuse carries out centralized classification, screening, magnetic separation laggard windrow corruption fermentation, then, and staged care；Wherein fines adds corresponding element as required and becomes the organic fertilizer for farmland；But, on the one hand this fines rotten through heap, classification decomposes not exclusively, belongs to in slow nutrient, and N, P, K ratio therein is uneven, C/N ratio is higher, and contained organic matter is also slow, so, the most treated that it is the most agricultural, it is difficult to play fertilizer efficiency.On the other hand, Natural fermentation not only needs large-area air storage place, and owing to sweat is in outdoor, fermentation odor smokes sky, in substance form a kind of new polluter.
Summary of the invention
That the purpose of the present invention is to provide the making of a kind of house refuse, fertilizer efficiency micro-element nutrition composition high, organic is many, the method that do not has the organic composite fertilizer polluted.
The purpose of the present invention is realized in, it comprises the following steps: the house refuse after heap corruption carries out scalping, magnetic separation, broken, screening to composite heat transfer base material, then according to the nutrient needed for different crops, design rational formula, nutrient insufficient section can use inorganic fertilizer to add, and remixes, granulating.Before carrying out scalping, carry out being evaporated deodorizing sterilizing in first house refuse is transported to drying unit and process.
Temperature in drying unit controls at 230 DEG C-350 DEG C, and utilize rotary action and the quantity of charging of drying roller on drying unit, control the rubbish time of staying in drying roller, carry out the humidity of rubbish of magnetic separation after making drying between 15%-20%.
In technical scheme, also the rubbish after screening can be carried out an infrared and ultraviolet line again and disinfect.
The present invention, compared with existing production technology, has corruption fully, does not pollute, technical maturity, the advantages such as manufacturing requirements is low, easy operation, have higher practical reference value.
Preferably selecting through natural fermentation, the house refuse becoming thoroughly decomposed or partly become thoroughly decomposed under natural environment, because such rubbish content of organic matter is high, partially protein is enclosed within internal by microorganism, and it can play more preferable decomposition in follow-up technique.First with belt conveyer, rubbish is transported on the cylinder of drying unit carry out being evaporated deodorizing sterilizing process, the operation of drying unit is to send hot blast by air stove, pressure fan to cylinder, to ensure that the temperature in rolling controls at about 300 DEG C, and utilize the quantity of charging and the rotary action of cylinder, control rubbish time of staying in cylinder so that the rubbish humidity after drying is at 15%-20%, simultaneously, during drying, with the foul smell in exhaust blower suction cylinder, waste gas；Foul smell, the waste gas extracted out are discharged after deodorization chamber * winding paper, wash water tower, water treatment facilities process, thus are decreased the pollution of environment.Second step scalping, magnetic separation, broken, screening: the rubbish after belt conveyer will be evaporated deodorization is sent to the scalping machine of 40mm sieve aperture and carries out scalping, magnetic separation will be sent into less than 40mm thin block powder, remove iron filings, pulverize with pulverizer again, then it is fed again into screening machine dusting cover, yields less than below 3mm organic fertilizer base material.3rd step infrared and ultraviolet sterilization: the house refuse after dusting cover is transported to infrared sterilizing equipment decontaminating apparatus and carries out infrared and ultraviolet sterilization, to reach the antibacterial killing in rubbish.4th step compound organic fertilizer produces: measures the organic fertilizer base material constituent content after sterilization, and according to the nutrient needed for different crops and needs, carries out dispensing, after being then sufficiently mixed uniformly, adopts and carries out pelletize by any known method, obtain product of the present invention.
Claims (3)
1. the method making organic granular compound fertilizer by house refuse: it comprises the following steps: the house refuse after heap corruption is carried out scalping, magnetic separation, broken, screening, dispensing, mixing, a pelletize,
It is characterized in that: before carrying out scalping, carry out in house refuse is first transported to drying unit being evaporated, deodorization, sterilization processing.
House refuse the most according to claim 1 makes the method for organic Ke Liao compound fertilizer, it is characterized in that: described drying unit, its interior temperature controls at 230 DEG C-350 DEG C, and utilizes the rotary action of cylinder and the quantity of charging, control the rubbish time of staying in drying unit
Making the rubbish humidity after drying is 15%-20%.
House refuse the most according to claim 1 and 2 makes the side of organic Ke Liao compound fertilizer
Method, it is characterised in that: the house refuse after screening carries out an infrared and ultraviolet line sterilization again.
