Abstract
The invention relates to a treatment method of kitchen garbage. The method comprises the following steps: sorting the kitchen garbage, and detecting out the ingredients which are difficult to transform, such as plastics; carrying out primary crushing on the kitchen garbage; carrying out dehydration on powder and removing moisture in the powder; feeding fermentation materials to the dewatered garbage, crushing the mixture, and then evenly mixing the raw materials with the fermentation materials; carrying out aerobic fermentation on the mixture for 12-15 days; and screening after fermenting. Through use of the method, dehydration is carried out before fermentation, so that the air permeability of the powder is increased, the biochemical reaction rate and the conversion ratio of the fermentation process are greatly increased, the garbage treatment cycle is shortened by 50%, the content of the screened organic matter reaches 80-90%, eggs of flies and the like are effectively prevented from generating and breeding, in addition, a harmful gas is prevented from escaping by spraying deodorization in the fermentation process, and the method is safe and environmentally friendly. According to the method disclosed by the invention, the garbage treatment cost is saved, meanwhile, the problem of environmental pollution is solved, and the method has significant economic and social benefits.
Description
Technical field
The present invention relates to technical field of waste treatment, particularly the treatment process of rubbish from cooking.
background technology
In recent years, due to being on the rise of environmental pollution, especially domestic refuse is on the impact of environment, has caused and has paid attention to widely, particularly rubbish from cooking, water content, organism amount, grease and saltiness are high, easy corruption, with traditional burying method, causes the waste of land resources, and the pollution of serious air and water quality, the health of harm people and animals.The biochemical treatment process transferring the science of comparison to is started to the process of rubbish from cooking both at home and abroad, through process, rubbish is become available resource.But complete mechanical means also costly, drop into general 500 ~ about 8,000,000.
Application number is disclose a kind of rubbish from cooking biological treating equipment and method in the Chinese invention application of 201410089559.6, and its method comprises: sorting, pulverize, add fermentation auxiliary material pulverize again, Natural compost, fermentation, screening.The feature of the method is the direct Natural compost fermentation of mixed powder, and fermentation time 20 ~ 35 days, filters out organism 20 ~ 40%, and 60 ~ 80% is residue.The plant equipment cost utilizing the method to use is higher.
Adopt above-mentioned waste disposal method, the subject matter existed is: equipment investment is high, the rear directly compost fermentation of pulverizing, sewage content is high, produce that peculiar smell is large in fermenting process, about one month time of long processing period-, garbage conversion rate are low-screening after organic content can be utilized lower, only account for 20-40%.
summary of the invention
For solving the problem, the invention provides a kind for the treatment of process of rubbish from cooking, comprising: rubbish from cooking is sorted, detect the composition that plastics etc. are difficult to transform; Residual refuse is pulverized for the first time; Powder is carried out processed; Fermentation auxiliary material is thrown in the rubbish after processed; Again compound is pulverized, make raw material and fermentation auxiliary material Homogeneous phase mixing; Compound is carried out aerobic fermentation 12 ~ 16 days; Ferment laggard row filter, wherein the organism of 80 ~ 90%, the residue of 10 ~ 20%.
For realizing the object of the present invention, selected fermentation auxiliary material is three material, i.e. wood chip, charcoal and complex micro organism fungicide, uses three material fermenting process release of heat high and not by extraneous temperature difference influence.Preferably, powder is followed successively by with the ratio of wood chip, charcoal and complex micro organism fungicide: 100:(8 ~ 12), (1.5-2.5), (0.00003 ~ 0.00005).
As preferred version of the present invention, all carried out under sealing condition before fermentation after first pulverizing.Scattering and disappearing and pollution to environment of effectively anti-stage raw material here.
For making the present invention obtain best effect, the flow process of aerobic fermentation is: first use poromeric material shop fixtures, and will mix stockpile static thereon three days, temperature rises to more than 50 degree Celsius; Thereafter turning every day in about 7 days once, makes it fully to contact with oxygen, and to complete biochemical reaction, and utilize spray equipment deodorizing, temperature is at 60 ~ 72 degrees Celsius; Temperature; Turning every day 1 time in last about four days, reducing temperature and humidity, temperature is down to less than 50 degree Celsius.
The organism filtered out, indices is all up to state standards, and is widely used in gardens, greening and flower culture; Organic vegetable matrix fertilizer (soilless culture); Make the fermentation raw material of poultry fertilizer; Culture medium of edible fungus and making biomass fuel rod etc.Remaining residue recycles as the grate-layer material of fermentation, and existing good ventilation property, can play katalysis again, accelerate fermenting speed, shorten fermentation time.
Compared with prior art, the present invention has following beneficial effect:
Owing to have employed processed and namely sealing treatment accomplishes zero sewage outflow, effectively prevent generation and the breeding of the harmful organisms such as fly class, and the spray deodorizing of fermenting process, all serve the effect of purifying treatment environment, increase the loft of fermentation material simultaneously, expand the contact area with oxygen, in addition with the residue shop fixtures filtered out, the biochemical reaction speed of great quickening fermenting process, shortens fermentation time, improves organic transformation efficiency.Use this treatment process, mechanical means cost is about 1,000,000, and economic and social benefit is remarkable.
