Abstract
The invention discloses a kitchen food waste composting method, and a technology using the method in treatment of secondary salinization land. The kitchen food waste composting method comprises the following steps: collecting and classifying kitchen wastes, carrying out solid and liquid separation on the kitchen wastes, reserving separated solid waste residues, adding bagasse and corn stalks, and uniformly mixing all above materials. The kitchen food waste composting method is a method for making a fertilizer by composting wastes, the technology using the method in treatment of secondary salinization land is used for treating the secondary salinization land through the produced fertilizer. The kitchen food wastes are composted to make the fertilizer, so environment pollution and city appearance affection are solved, propagation of diseases is avoided, the running cost of waste treatment is reduced, the economy effect is improved, and wastes are changed into valuables.
Description
Technical field
The present invention relates to kitchen waste compost and Saline-alkali Field Control technical field, specially a kind of kitchen waste compost method
And its method for secondary salinization of land improvement.
Background technology
Compared with Other Waste, changing food waste poisonous and harmful substance (as heavy metal etc.) content is few, but the speed that rots
Hurry up, easily grow antibacterial, particularly high temperature season is perishable rotten, leads to the harmful substances such as pathogenic microorganism and mycotoxin rapid
Amount reproduction.Following harm and difficulty can be caused：
1st, pollution environment and the impact appearance of the city.Because changing food waste contains higher organic matter and moisture, easily it is subject to microorganism
Effect, and the phenomenon that rots；And discarded standing time is more long, putrid and deteriorated phenomenon is just serious all the more.Particularly arrive
Summer, temperature is higher, rots also faster, at this time easily produces substantial amounts of leakage water and foul gass, grows mosquito
Worm, makes a very bad impression to environmental health.
2nd, spread disease.The outdoor storage of changing food waste can cause the amount reproduction of mosquitos and flies Mus worm, and it is that disease spreads
Main media.
The lower sepage producing when the 3rd, stacking in changing food waste enters into sewage disposal system, can cause the increasing of content of organics
Plus, thus increasing the burden of sewage treatment plant, increase operating cost.
Therefore, the process for changing food waste need to change traditional waste disposal method, need to turn waste into wealth.And in rubbish
The area piled up or the area because of other environmental effects, unexpected complicated component, saline and alkaline content is not up to standard, leads to soil function to drop
Low it is difficult to useful, need to administer.
To sum up can obtain, changing food waste is processed by the method for compost, the fertilizer of restraint, and can be entered by this fertilizer
Row administers salt-soda soil, kills two birds with one stone, therefore we have proposed a kind of kitchen waste compost method and its control for secondary salinization of land
The method of reason.
Content of the invention
(1) technical problem solving
For the deficiencies in the prior art, the invention provides a kind of kitchen waste compost method and its be used for secondary salinization of land
The method administered, solves the problems, such as the bad cleaning of changing food waste and pollution environment.
(2) technical scheme
For realizing object above, the present invention is achieved by the following technical programs：
A kind of kitchen waste compost method, comprises the following steps：
A1, collection sorting rubbish：Collect described changing food waste, described changing food waste solid is separated with liquid, retain
Solid slag after separating, adds bagasse and corn straw, and mix homogeneously；
A2, first time compost fermentation：To in the solid slag of mix homogeneously add strain, length and width be 40 meters and
High six meters of the first fermentation is indoor, the solid slag processing is piled several buttress, the length of bar buttress is 3-5 rice, width
For 3-4 rice, high 2 meters, and press the ventilating system that the quantity of bar buttress arranges respective amount around place, ventilating system includes air blast
Machine and aerator automatic control system, to carry out forced ventilation to bar buttress, and control the temperature of the first fermenting cellar, in the temperature of bar buttress
After degree reaches 75 degrees Celsius, lowered the temperature, after cooling, itself fermentation liter high-temperature is being piled up neatly by bar, circulating 4-5 days with this
Can get the fermented product of first time compost fermentation；
A3, second compost fermentation：The fermented product of first time compost fermentation is compressed processed and adds catalysis again
Agent, is then delivered to the second fermentation interior that length and width are 40 meters and high three meters, and the fermented product heap that will add catalyst is grown up
The bar buttress of 3-5 rice, wide 3-4 rice and high 1-1.5 rice, carries out second fermentation, temperature is simultaneously maintained 50 by regulating and controlling temperature always
About degree, reaching becomes thoroughly decomposed can get fertilizer, and neutralizes in second composting fermentation process in first time composting fermentation process, will
The foul smell that fermentation produces carries out deodorizing process, foul smell will be discharged to biofilter by gas extraction system and absorbed；
A4, processing are collected：First fertilizer is dropped to room temperature, fertilizer is being crushed, is being sieved through screening plant after crushing
Point, then again pelletize is carried out to it, collect after granulated fertilizer Drying and cooling.
A kind of kitchen waste compost is used for the method that secondary salinization of land is administered, and comprises the following steps：
S1, get the raw materials ready：The granulated fertilizer that above-mentioned changing food waste is prepared into carries out pulverization process and obtains fertilizer powder；
S2, pretreatment：The salt-soda soil needing to administer is carried out process of digging, then diversion pouring carries out salt discharge process, dries
Dig again afterwards；
S3, fertilizer powder is uniformly sprinkling upon on the soil of pretreatment, is then neutralized acid treatment.
(3) beneficial effect
The invention provides a kind of kitchen waste compost method and its method administered for secondary salinization of land.Possess following
Beneficial effect：
(1) the invention provides a kind of kitchen waste compost method and its for secondary salinization of land administer method, this meal
Kitchen waste compost method and its method administered for secondary salinization of land include manufacturing using garbage compost fertilizer method and
The method being used for by the fertilizer made administering secondary salinization of land, is prepared into fertilizer by changing food waste is carried out compost method,
Solve pollution environment and the effect of the impact appearance of the city, and it can be avoided that transmission of disease, the operation also reducing garbage disposal becomes
This, improve economic benefits, turn waste into wealth.
(2), the present invention carries out administering salt-soda soil by the fertilizer that changing food waste is made, and not only solves the place of changing food waste
Reason difficulty, additionally it is possible to effectively administer salt-soda soil, is killed two birds with one stone, and improves economic growth.
