Abstract
The invention provides a biotransformation method for utilizing cultured earthworms to treat organic wastes. The earthworms are placed in fermented organic wastes, and life activities of the earthworms are utilized to treat the organic wastes. By means of the synergistic effects of various enzymes and microorganisms in the digestive tracts of the earthworms, the organic substances in the wastes undergo decomposition and transformation, thus finally forming usable earthworm manure. The invention also puts forward a series of environmental parameters suitable for earthworm survival through experiments, like pH value, temperature, humidity, ventilation, illumination and the like.
Description
Technical field
This patent has proposed a kind of utilization propagates earthworm artificially and processes the bioconversion method of organic waste.Earthworm is put in a suitable place to breed in organic waste by fermentation, utilized the vital movement of earthworm to process organic waste.By the synergy of various enzymes and microorganism in earthworm digestive tube, make organic substance decomposition and inversion in waste, finally form available earthworm excrement.
Background technology
At present Urban Garbage Treatment in China is taking sanitary landfill as main, then is aided with compost and burning.But these means all drawback are heavy.Landfill disposal needs the investment of wholesale, and takies a large amount of land resources, although burning method can utilize garbage power, input is very large, and can produce a large amount of obnoxious flavour in burning process, severe contamination atmospheric environment.Although composting process has resource utilization, free of contamination feature, the amount of money of required investment is also very surprising.
Earthworm is as a kind of Omnivore, and feeding habits are wide, heavy.Earthworm, except not eating metal, glass, plastics and rubber, can eat various organic wastes, in a large number as the waste residue mud in paper plant, sugar refinery, food factory, aquatic product manufactory, brewery and ditch.The organism such as feces of livestock and poultry, pericarp dish slag, rag waste paper, weeds wood chip and rubbish are all the good feeds of earthworm.Article 100000000, the earthworm rubbish of 40 ~ 50t of can eating for one day, discharges 20t earthworm excrement.Visible earthworm has the function that promotes that material decomposition transforms in natural, ecological.
Summary of the invention
Object one of the present invention is the feature of utilizing earthworm feeding habits wide, heavy, the flow process and the reactor that provide a kind of breeding earthworm to process organic garbage of city.
Object two of the present invention is to draw by experiment the top condition that is applicable to earthworm Growth and reproduction, comprises the parameters such as temperature, humidity, pH value.
According to object one of the present invention, the method for utilizing dealing with earthworm organic waste that this patent proposes is as described below: utilize dealing with earthworm organic waste to need pre-treatment and two programs of final processing.Pre-treatment is classified organic component in waste and inorganic composition exactly.The useless dish leaf of picture, pericarp, leftover etc. hold labile rubbish, can directly be ground into chip that earthworm easily eats directly offers earthworm and processes, the fibre contents such as enough stalks, excrement of animals, industrial residue are high and have the solid waste of germ, need the process of sterilizing by fermentation and matured compost just can offer earthworm and process.Final processing is that earthworm carries out final processing by earthworm reactor to pretreated waste.Earthworm reactor is shown in accompanying drawing 2
According to object two of the present invention, the main technical details that this patent sums up following applicable dealing with earthworm waste is as follows:
Temperature: optimum temperuture is 18 ~ 27 DEG C, in this temperature range, earthworm development rate is moderate, and thermal energy consumption is few, and motility is strong, strong strong, lays eggs many, and mortality ratio is low.
Humidity: the absolute humidity of the required feed of earthworm growth and development is approximately 35 ~ 40%, if excessively wet, can cause earthworm expiratory dyspnea, if overdrying can affect growing of earthworm.For becoming earthworm, high humidity is about 38% left and right, and young earthworm is in 35% left and right, and the humidity of egg follicle hatching is in 31% left and right.
Ventilation: as CO in raw material
2concentration exceedes 11%, when the concentration of ammonia exceedes 17uL/L, concentration of hydrogen sulfide and exceedes 20uL/L, methane concentration and exceed 15uL/L, can cause earthworm death.
PH value: the Acidity Range that earthworm can be stood environment is larger, pH value is greatly about 6 ~ 8, but in feed with neutral or micro-acid for well, pH value is too low or too highly all can cause that earthworm runs away.
Illumination: earthworm keeps in dark place, blaze is unfavorable for the growth of earthworm, UV-light has hormesis to earthworm, at white light, scattered light, special unglazed in the situation that, can normal growth breeding.
Feed: earthworm is afraid of salt, is afraid of tannin taste, taking the organism that rots, potential of hydrogen is applicable to, salinity is not high as food.
Stand density: 20,000 ~ 30,000/square meter
In dealing with earthworm waste process, mainly contain two large products, the one, earthworm itself, the 2nd, wormcast.Earthworm itself can be used as the feed of other animals, can also be used to extract the medicinal substances such as enzyme, hormone, albumen, antibacterial peptide, and wormcast can be used as the fertilizer of other plant-growth, and earthworm and wormcast extract have unique diseases prevention, insect protected function.
Beneficial effect of the present invention is: utilizing dealing with earthworm organic waste, not only eliminated a large amount of refuses, mud can also be become to the neutral fertilizer of high-quality, and finally obtain a large amount of stable performances, can utilize earthworm excrement, is to achieve many things at one stroke.This method not only cost is low, there is no secondary pollution, and can make organic waste regeneration increment.

Embodiment
To a preferred embodiment of the present invention will be described in detail, should be appreciated that following illustrated preferred embodiment, only for description and interpretation the present invention, is not intended to limit the present invention below in conjunction with accompanying drawing.
Fig. 1 is the dealing with earthworm waste flow process figure that utilizes provided by the invention, as shown in Figure 1:
Municipal wastes is divided and picks organic constituent and inorganic component
For can directly pulverizing and put in reactor as dish leaf, pericarp and so on being labile
The high rubbish of fibre content as stalk etc., needs to put into reactor after sterilizing by fermentation, matured compost
Fig. 2 is earthworm reactor provided by the invention, as shown in Figure 2:
This earthworm reactor is made up of feed appliance, main reactor, screen cloth, discharger four parts, main reactor is the place of dealing with earthworm waste, by the mode automatic monitoring earthworm living environment (temperature, humidity, pH value, air permeability etc.) of central modulator, the bottom of main reactor adopts mesh structure, earthworm as a kind of processing machine of work, accelerates the decomposition and inversion of organic substance in waste with microorganism synergy in main reactor.
