Abstract
The invention discloses a method for removing foul smell of night soil particles through simple composting. According to the method, a YPD yeast culture solution is sprayed to the night soil particles, the YPD yeast culture solution contains saccharomycete and metabolite of the saccharomycete, the night soil particles are piled up to form a pile, on the second day, the night soil particle pile begins to be turned over and piled twice every day, when the pile is turned over and piled on the fourth day to the sixth day, plant ash is added, when the pile is turned over and piled on the sixth day to the eighth day, some activated carbon powder is added, and then night soil particle fertilizer is obtained. The saccharomycete of the yeast culture solution can take odorous substances such as ammonia, hydrogen sulfide and methyl mercaptan in the night soil particles as energy substances, so that foul smell is reduced, the foul smell can be reduced by 85% or above, the activated carbon powder and the plant ash can also absorb a part of the foul smell, and the foul smell is further reduced. According to the simple composting method, blasting, temperature rising and pressure rising are not needed, the technology is simple, treatment time is short, treatment cost is low, moreover, the foul smell after the night soil particles are treated is little, and the foul smell is avoided in the transportation and fertilization processes.
Description
Technical field
The present invention relates to the deodour method of fertilizer, and in particular to a kind of to remove excrement solid impurity particle stink by simple compost
Method.
Background technology
Excrement solid impurity particle fertilizer is city anaerobic tank or the precipitate in public lavatory particulate matter made by Jing after processing, and is often used as fruit
The fertilizer of vegetable.Excrement solid impurity particle fertilizer has good fertilizer efficiency, but the dense stench discharged in its transhipment, application is limited
Promoting the use of for granular fertilizer, such as the fruit and vegerable garden particularly plucked for scene, strawberry field, Fructus Mori garden etc..At present to manure of livestock and poultry
Just or public toilet faeces excrement solid impurity particle fertilizer tends to process excrement slag using aerobic compost method, aerobic compost method be divided into pretreatment, one
The workshop section such as secondary fermentation, ferment in second time, sewage disposal and Odor control and solid-state fertilizer storage, its complex process, process time are long, place
Reason high cost；Therefore such as the application for a patent for invention of Publication No. CN101092310, disclose a kind of letter of compost technique from dung dregs
Easy composting process, the technique need to be piled up in special compost, in addition it is also necessary to ventilation shaft and aerator, at the same will using intensification,
Supercharging, the technique of oxygen supplement.Aerobic compost is relatively costly, even if the excrement slag after the process of such method, can be after night soil-treatment
Storage, transport and use during discharge again, be actually administered to the afforestation such as municipal administration, residential area and fruit and vegerable
Strong foul smell can be given out during garden, if being used for family potted plant, due to be indoors or balcony, its foul smell distribute after to room
Interior air pollution is fairly obvious, does not meet《Emission standard for odor pollutants》Foul smell emission request（GB14554-1993）, and
This problem is not yet resolved in traditional fertilization.
The content of the invention
The technical problem to be solved is to provide a kind of method for removing excrement solid impurity particle stink by simple compost,
The simple compost method process is simple, process time are short, and processing cost is low, and excrement solid impurity particle stink is little after processing.
The technological means of technical problem of the solution of the present invention are：It is a kind of that excrement solid impurity particle stink is removed by simple compost
Method, its step are as follows：
A, in excrement solid impurity particle uniform sprinkling YPD Yeast Cultivation liquid, the bulking value of the excrement solid impurity particle and YPD Yeast Cultivation liquid
Than for 1 kilogram：50 milliliters, the YPD Yeast Cultivations liquid is cultivated in the liquid YPD medium that pH is 5.0～5.5 by yeast and is obtained
, in the YPD Yeast Cultivations liquid, saccharomycetic concentration is 8 × 107～5.5 × 1012Cfu/ milliliters, the liquid YPD cultures
Contain yeast extract powder, peptone and glucose in base, the weight of the yeast extract powder is liquid YPD medium gross weight
1%, the weight of the peptone is the 2% of liquid YPD medium gross weight, and the weight of the glucose is liquid YPD medium
The 2% of gross weight；
B, the above-mentioned excrement solid impurity particle for being sprayed with Yeast Cultivation liquid is piled into weight for 1000～3000 kilograms of excrement solid impurity particle heaps, from the
2 days start daily to excrement solid impurity particle heap turning 2 times, each turning 10～30 minutes；
C, excrement solid impurity particle heap are piled up the 4th～6 day, during first time turning, add the grass of excrement solid impurity particle heap gross weight 1% in turning
Wood ash, excrement solid impurity particle heap are piled up the 6th～8 day, during first time turning, add excrement solid impurity particle heap gross weight 0.5～1% in turning
Activated carbon powder, then obtain excrement solid impurity particle fertilizer.
In step a, in the YPD Yeast Cultivations liquid, saccharomycetic concentration is 6.9 × 1010 Cfu/ milliliters.
In stepb, every heap excrement solid impurity particle heap gross weight is 2000 kilograms；So turning operation is easier to, turning effect
Also it is preferable.
Compared with prior art, it is an advantage of the current invention that a kind of side for removing excrement solid impurity particle stink by simple compost
Method, the method is first to spray YPD Yeast Cultivation liquid in excrement solid impurity particle, and YPD Yeast Cultivation liquid contains yeast and its metabolite,
Pile up in heaps again, start within the 2nd day it is secondary to the daily turning of excrement solid impurity particle heap, pile up turning in the 4th～6 day when add a little plant ash,
Add a little activated carbon powders when piling up turning in the 6th～8 day, then obtain excrement solid impurity particle fertilizer；The yeast of Yeast Cultivation liquid of the present invention
, be able to can drop using the odorous substance such as ammonia, hydrogen sulfide, methanthiol in excrement solid impurity particle as its energy substance so as to reduce foul smell
Low by more than 85%, activated carbon powder and plant ash can also absorb part foul smell, foul smell is further declined, the simple heap of the present invention
Fertile method does not need air blast, intensification, boosting, and process is simple, process time are short, and processing cost is low, and stink is little after processing, no
Stink can be produced during transport and fertilising.
