Description

A kind of process units of aerobic fermentation composting organic fertilizer
Technical field
The utility model is related to a kind of process units of aerobic fermentation composting organic fertilizer, belongs to solid organic castoff aerobic Compost treatment field.
Background technology
Compost is generally divided into aerobic compost and anaerobic composting.Aerobic compost is the decomposition of the organic matter in the case where there is Oxygen Condition Journey, aerobic bacteria is absorbed to waste, aoxidized, decomposed, and its metabolite is mainly carbon dioxide, water and heat;Anaerobic composting is Organic matter decomposition is carried out under anoxic conditions, and the last metabolite of anaerobic digestion is methane, carbon dioxide and many low molecules The intermediate product of amount, such as organic acid.Anaerobic composting is compared with aerobic compost, the energy of the organic matter degradation generation of Unit Weight Amount is less, and anaerobic composting is typically easy to produce stink.For these reasons, almost all of compost engineering system is all used Aerobic compost.Composting process can reach the purpose of pathogen and weed seed in composting material in preferable raw material dehydration, killing, The cost of this method processing is relatively low, and the complete compost after processing can reach innoxious requirement, if be further added by certain follow-up The fertile technique of system, finished product can direct land use.
The process of good sample compost typically divides three phases:1) temperature rise period refers generally to the initial stage of composting process, in the stage, Heap temperature progressively rises to 45 DEG C or so from environment temperature, dominates microorganism based on mesophilic property microorganism, including fungi, thin Bacterium and actinomyces, decompose substrate based on carbohydrate and starch.2) temperature rise of hot stage heap is to enter high temperature rank to more than 45 DEG C Section, in this stage, mesophilic microorganism is suppressed even death, and thermophilic microorganism then rises to leading microorganism.Compost Middle residual and the soluble organic matter that is newly formed, which continue to be oxidized, to be decomposed, complicated organic matter such as hemicellulose, cellulose and Protein is also begun to by intensive decomposition.The activity of microorganism is also what is be alternately present, generally most active at 50 DEG C or so to be Thermophilic fungi and actinomyces, fungi is almost stopped action completely when temperature rises to 60 DEG C, only thermophilic bacteria and unwrapping wire Bacterium activity, temperature when being raised to 70 DEG C most of thermophilic microorganisms no longer adapt to, and roll into the dead and dormant stage.It is existing The optimum temperature that generationization compost is produced is generally 55 DEG C, because most of microbe is most active within the range, most easily divides Organic matter is solved, most of parasitic ovum and pathogenic microorganism therein can be killed.3) temperature-fall period hot stage is necessarily caused The death and activity reduction of microorganism, enter cold stage naturally.In this stage, mesophilic property microorganism starts to occupy excellent again Gesture, it is further to the organic matter of remaining more difficult decomposition to be decomposed, but microbial activity is generally reduced, and heap body caloric value is reduced, Temperature is begun to decline, and tending towards stability of organic matter, oxygen demand greatly reduces, and compost, which enters, to become thoroughly decomposed or the after-ripening stage.
The oxygen supply of aerobic compost mainly has static air blast oxygen supply and dynamic to turn over throwing oxygen supply two ways, air blower aeration aerating It is constantly to transmit air to heap body using the airduct for being located at compost material bottom, reaches the purpose of oxygenation.It is profit to turn over throwing oxygenation Material is set to carry out short-time contact with air with turner operation, so as to supplement partial oxidation.Two kinds of oxygenation modes respectively have its excellent Shortcoming:The time of blast aeration oxygenation is long, and the oxygenation time is more flexible, can carry out oxygen supply at any time as needed, especially It is that under the monitoring and aerobic condition using automatic monitored control system progress oxygen, can at any time be entered according to the oxygen Expenditure Levels of heap body Row aeration aerating, it is ensured that the sufficient supply of heap body oxygen, so as to prevent heap body from the smelly possibility of anaerobism occur, it is ensured that plant area Environmental sanitation.But, if aeration excess or continuous aeration, not only the damage of amount of heat in heap body can be caused because ventilation is excessive Lose, cause heap temperature to decline, while can also increase energy consumption.Therefore, ventilation time should be in good time, and ventilation also must be suitable, Can not too greatly or very little.Turn over throwing oxygenation then to be turned over the contact in a flash with air of throwing using material and realize oxygenation, turn over throwing and fill Oxygen can guarantee that the uniform of whole heap body, it is to avoid the dead angle in fermentation cabin, but it is short to turn over the throwing oxygenation time, and turns over throwing number of times daily All there is serious oxygen oxygen supply in limited (typically daily can only turning and throwing once), the most of the time in composting process not enough Problem.Because in the Rapid Fermentation stage of compost, oxygen consumption is very fast, sometimes can be so that the oxygen of heap body in half an hour Concentration drops to the oxygen threshold (7%~8%) for producing the foul smell such as hydrogen sulfide.Therefore, only relied in composting process turn over throw into Row oxygenation, then inevitably leading to the most of the time has anaerobism, so as to cause the environmental sanitation of stench and mosquitos and flies Problem, and frequently turn in the compost megathermal period throwing and can cause the volatilization of a large amount of ammonias.Aerobic compost is tested and engineering operation shows: Initial stage and mid-term in compost, the keto consumpting speed of aerobic fermentation is quickly;Particularly in hot stage, make by the oxygenation of turner With requirement can not be met, therefore the long-term anaerobism period occurs, so as to cause the generation of stench and mosquitos and flies problem, while significantly The stability of degree reduction compost.Throwing effect is turned over due to turner, the temperature in heap body can be caused to be rapidly decreased to room by high temperature Temperature, changes heap temperature indention, destroys preferable aerobic fermentation temperature heating and keeps process, is unfavorable for realizing compost Sterilizing and kill the process of the innoxious process such as weed seed, and be unfavorable for playing the fast degradation of hot stage microorganism Function.
The oxygen monitoring of composting process and control:Oxygen is to influence the important parameter of microbial activity and composting process, is filled The oxygen of foot is to ensure the necessary condition that aerobic composting process is smoothly completed.Using compost oxygen, temperature automatic on-line monitoring dress Monitoring heap body oxygen content situation is put, compost state can be clearly judged, foundation is provided for the control of air blower.Compost initial stage (detonation phase and temperature raising period) micro organism quantity is less, activity is relatively low, and heap body is little to the demand of oxygen, this stage air blast strategy Oxygen content situation using heap body is foundation, preferably using small air quantity air blast, in order to avoid take away heap body heat content;When temperature is increased to high temperature After phase, microorganism obtains amount reproduction, and activity is also higher, and OUR is very fast, and this stage easily uses the larger blow rate required, with band Heap body moisture is walked, the oxygen of abundance is provided for heap body;After heap body enters cooldown period, the temperature reduction of heap body, to oxygen Demand reduce, this stage using aeration aerating with turn over throwing be oxygenated be combined by the way of.
The temperature monitoring of composting process and control:Heap temperature is another important indicator of high temperature aerobic composting.It is closed The innoxious degree such as fermenting speed, stabilization effect, dewatering efficiency, sterilizing and the bioinactivation being tied in composting process.In height Thermophilic high temperature microbe in thermophase, heap body can be with amount reproduction, and the biodegradable efficiency of thermophilic high temperature microbe is than other micro- lifes Thing is high, and high temperature not only contributes to accelerate composting process, and is conducive to the weed seed that sterilizes and kill, therefore is compost hazard-free The stage of most critical in processing.But, if heap temperature is too high, all microorganisms can be caused all to be killed or dormancy, So as to reduce the fermentation efficiency of composting process, therefore have a negative impact on the contrary to composting process.In four ranks of aerobic compost Duan Zhong, the too high course of fermentation for being also unfavorable for compost of temperature.Therefore the temperature of compost must be monitored and is controlled, reached Optimal temperature conditionss, to promote in heap body beneficial microorganism amount reproduction to greatest extent and mushroom out.Turn over throwing meeting It is low when high when causing the temperature of heap body, obvious zigzag is presented, so as to be unfavorable for sterilizing and the flash-ferm process of compost.Ginseng Examine China《Decontamination of human excreta sanitary standard》(GB7959-87) aerobic composting process design standard and specification, it is desirable to which high temperature is sent out Ferment process must assure that in heap body temperature of charge more than 50 DEG C and be kept for 5~7 days.Therefore, turn over throwing technique maximum one lacks It is that can not meet more than the 50 DEG C innoxious basic demands for continuing 5~7 days to fall into.And use based on the static state under the conditions of forced ventilation Composting process, then the temperature of heap body can be monitored and controlled automatically, it is in optimum state all the time, so as to avoid individually turning over throwing Defect, well meet more than 50 DEG C continue 5~7 days innoxious basic demands.Therefore, it is unsuitable independent in composting process Using turning over throwing technique, but the automatic monitoring and control of trip temperature should be entered during one time fermentation, in secondary fermentation process It is middle to carry out appropriate turning over throwing.
And traditional well foster composting device structure is complex, thereby increases and it is possible to occur, to compost heap oxygen supply deficiency, causing Fermentation is not thorough, while probably due to drainage effect is poor, the discharge of influence percolate influences the effect of compost.
