Abstract
The invention relates to an ins-situ pretreatment method of solid organic waste resources (catering wastes, domestic garbage, garbage in vegetable markets, brewer grains, distiller grains, stevia rebaudiana waste residues, traditional Chinese dregs, wastes in slaughter houses, wastes in culturing farms and the like). Mixed bacterial are added into the organic wastes at temporary storage places of the solid organic wastes (garbage cans, sewer manholes, scrapyards and the like) and stood and treated in a natural state. The invention discloses a method for effectively solving the treatment on the solid organic wastes from the generation to the treatment, which thoroughly controls the hazards brought by the solid organic wastes, such as mosquito breeding, stink, pathogenic microorganism infection and the like and provides prerequisite conditions for post treatment of the solid organic wastes and realization of hazard-free treatment, reclamation and reduction of waste resources.
Description
Technical field
The present invention relates to a kind of solid organic castoff preprocess method, particularly, be by mixed microorganism in the solid organic castoff storing containers or the storing place it is handled, thereby controlled from the source that solid organic castoff brings such as mosquito grow, harm such as stench, cause pathogeny imcrobe infection, be the post processing of solid organic castoff simultaneously, realized that the recycling and minimizing of waste resource provides prerequisite.
Background technology
At present, along with the continuous growth of population, growth in the living standard and industry, agricultural economy are more and more flourishing, produced a large amount of solid organic castoffs every day, if these solid organic castoffs adopt landfill or burning disposal, both wasted a large amount of resources, take a large amount of soils again.In the rubbish that produces, great majority are organic matter in food garbage, house refuse and the food market rubbish, can roughly these organic matters be divided into protein-based, starch based, fats and cellulose family, these materials all are natural organic matters, comply with the call of national conservation-minded society, these benefit materials ought to be recycled.Simultaneously, also can produce certain solid waste in the industry, in the stevioside production process, extract stevioside after, remaining a large amount of stevia rebaudiana dregs, these stevia rebaudiana dregs can be delivered to the refuse depot, invisible like this increase the workload of garbage disposal; The extraction of medicinal herb components also can bring the generation of a large amount of medium-height grass dregs of a decoction, and this part medium-height grass dregs of a decoction will be dropped.The needs of urban development, needs of economic development can find a kind of method of handling solid organic castoff so need badly, realizes the minimizing of rubbish on the one hand, on the other hand organic waste can be utilized again.The present invention provides strong prerequisite for the realization of these targets, with the generation of these solid waste by certain means control mosquito, harmful microbe breeding and stench, for sufficient the preparation carried out in the processing of next step solid organic castoff, thereby alleviate the pressure that environment is caused, environment purification improves the appearance of the city, and reduces the use in landfill soil, realize the cleaner production of industry and agricultural, reduce the purpose to the pollution of environment simultaneously.
Summary of the invention
Controlled from the source that solid organic castoff brings such as mosquito grow, harm such as stench, cause pathogeny imcrobe infection, be the post processing of solid organic castoff simultaneously, realized that the recycling and minimizing of waste resource provides prerequisite.
The present invention realizes that the technical scheme of above-mentioned purpose is: will mix bacterium and mixing enzyme preparation and join in the container that has solid organic castoff, and leave standstill cultivation under the condition of (15～50 ℃) under field conditions (factors).
And described solid organic castoff comprises castoff of food and drink, house refuse and food market rubbish, brewex's grains, distillers ' grains, STEVIA REBAUDIANA waste residue, the medium-height grass dregs of a decoction, slaughterhouse discarded object, plant's discarded object etc.
And, described mixed bacterium is Lactobacillus plantarum (Lactobacillus plantarum), streptococcus thermophilus (Str.thermophilus), streptococcus lactis (Str.lactis) natto bacillus (Bacillus natto), bacillus pumilus (Bacilluspumilus), bacillus subtilis (Bacillus subtilis) and lactobacillus bulgaricus (Lactobacillusbulgaricus, L.b), bacillus stearothermophilus (Bacillus stearothermophilus), each bacterium is cultured to the exponential phase later stage separately, difference is (0.8-1.2: 1.0-1.2: 0.8-1.0: 1.0-1.4: 0.8-1.2: 0.6-0.8 by a certain percentage, v/v) mix, the addition of Mixed Microbes is 1～5% (v/v).
And described enzyme preparation is amylase, protease, cellulase, and the ratio between the various enzymes is 1-1.5: 1-2: 0.5-2, and v/v, mixing enzyme preparation addition are 0.2%-1% (v/v).
Mixed bacterium can be in 15～50 ℃ temperature range normal growth, need not to stir and evenly mix.
Advantage of the present invention and good effect are:
The present invention has found and a kind ofly can effectively carry out the pretreated technology of solid organic castoff original position, for the subsequent treatment of solid organic castoff provides prerequisite guarantee.
The microorganism that the present invention selects for use is people and animals and environmentally friendly safe bacterial strain, can suppress on the one hand growing of harmful microbe growth and mosquito, on the other hand, can not produce the secondary pollution such as stench etc. in its growth course.
