Description
Technical field
The utility model relates to compost treatment technical field, particularly a kind of compost treatment system for solid organic castoff.
Background technology
Along with expanding economy, the enormous amount that all kinds of solid organic castoff in China city and rural area produces, the current whole nation only feces of livestock and poultry generation just reaches 25-30 hundred million tons (fresh weight) every year.If this part solid organic castoff not in addition rationally disposal and utilization, not only can cause the waste of organic resources, but also can cause serious environmental pollution.During High-Temperature Composting is the technical measures that these solid organic castoffs realize harmless treatment and recycling, but During High-Temperature Composting ubiquity odor pollution problem, sometimes more serious than the innoxious problem of solid organic castoff, preventing in composting production process and eliminating stink pollution is a major issue that must solve.
The compound being identified as repugnant substance at present about has kind more than 20, in the deodorization and deodorizing engineering of reality, takes different measures according to main stink substance different properties.The foul smell composition of solid organic castoff compost factory mainly comprises non-volatile inorganic (VICs) and volatile organic matter (VOCs), mainly contains ammonia, sulfocompound, amine and some lower aliphatic acid substances etc.In organic castoff compost process, foul smell burst size is maximum generally occurs in pliotherm period and the agitation phases that thermophilic fermentation stage, particularly compost start latter several days.
The method of current compost odor treatment is adopt physics, chemistry and biological means substantially, the common method destroyed foul odors has WATER-WASHING METHOD, liquid facture, combustion method, absorption method, masking method, air dilution method etc., usually needs the corresponding independently stench processing system of auxiliary construction.In recent years more application biological odor removal method is started, major equipment for Odor control comprises biological filter and biological scrubber etc., these deodoration systems are invested relatively large usually, need the Odor control engineering of building separate unit equally, take certain land area, in engineering practice, still there is the problem such as deodorizing effect instability, operation and maintenance high cost.
Utility model content
Technical problem to be solved in the utility model is to provide high, the effective foul smell internal recycle process compositing system of a kind of waste-gas cleaning processing efficiency.
For solving the problems of the technologies described above adopted technical scheme: a kind of foul smell internal recycle process compositing system, comprise compost fermentation workshop and compost ageing workshop, compost groove and gas skirt is provided with in described compost fermentation workshop, described gas skirt to be positioned at above compost groove and to connect and compose foul smell circulation closed space with compost groove is airtight, described compost bottom land end is provided with multiple aeration opening, be connected with pipeline by gas blower between each described aeration opening with foul smell circulation closed space, bacteria bed is provided with in described compost ageing workshop, described bacteria bed has the upper strata chamber and lower chamber that are connected by multiple through hole, described upper strata chamber holds compost material as filtration filtrate, be connected with pipeline by induced draft fan between described lower chamber with foul smell circulation closed space.
In the technical scheme of above-mentioned foul smell internal recycle process compositing system, described compost groove and upper strata chamber are equipped with compost fermentation and turn over pushing mechanism and push away to turn over compost material.
In the technical scheme of above-mentioned foul smell internal recycle process compositing system, be connected and sealed by plastics roller shutter between described gas skirt and compost groove.
In the technical scheme of above-mentioned foul smell internal recycle process compositing system, described aeration opening is evenly arranged in compost bottom land end, and described through hole is evenly arranged in chamber bottom, upper strata.
In the technical scheme of above-mentioned foul smell internal recycle process compositing system, described gas blower is centrifugal fan, and described induced draft fan is Scroll-tupe blower fan.
Beneficial effect: the mode of the employing foul smell internal recycle in this foul smell internal recycle process compositing system in compost fermentation workshop is to the blast aeration of compost groove, foul smell composition is made repeatedly to circulate in heap body and be degraded on the one hand, reduce nitrogen loss, improve compost finished product nitrogen nutrient content, alleviate the pressure of follow-up foul smell pump-and-treat system simultaneously; Make full use of the hot steam that composting produces on the other hand, improve organic castoff compost processing efficiency.Compost ageing arranges bacteria bed in workshop, utilizes fresh compost bacteria bed being stacked transfer, utilizes fresh compost decompose as filtration medium and remove compost foul smell, promotes the further mummification of fresh compost simultaneously and become thoroughly decomposed.In addition, whole compositing system integrated design, engineering structure is simple, and easy to maintenance, without the need to building the Odor control engineering of separate unit, foul smell removal efficiency is high, can also can be mass continuously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
With reference to Fig. 1, a kind of foul smell internal recycle of the utility model process compositing system, comprise compost fermentation workshop 10 and compost ageing workshop 20, compost groove 11 and gas skirt 12 is provided with in compost fermentation workshop 10, gas skirt 12 to be positioned at above compost groove 11 and to connect and compose foul smell circulation closed space 13 with compost groove 11 is airtight, compost groove 11 bottom is provided with multiple aeration opening 14, be connected with pipeline 16 by gas blower 15 between each aeration opening 14 with foul smell circulation closed space 13, bacteria bed is provided with in compost ageing workshop 20, bacteria bed has the upper strata chamber 21 and lower chamber 22 that are connected by multiple through hole 23, upper strata chamber 21 holds compost material as filtration filtrate, be connected with pipeline 16 by induced draft fan 17 between lower chamber 22 with foul smell circulation closed space 13.
