Description
Technical field
It the utility model is related to cultivation night soil-treatment field, more particularly to a kind of cultivation excrement dirt reutilization system.
Background technology
As urbanization, industrialized constantly propulsion, cities and towns and industrial population are continuously increased, city meat product supply pressure
It is increasing, promote China's livestock breeding industry to develop towards scale, intensive direction.The farming industry life of this batch production
It is dirty that substantial amounts of excrement can be produced during production, if excrement dirt is without any processing directly discharge, farmland and stream are entered by overland flow,
Small watershed water body environment will be polluted, and cause to close on water body ammonia nitrogen and organic matter severe overweight, fecal sewage to water body and
The pollution of soil is mainly to be endangered caused by organic pollution and nitrogen, phosphorus nutrition material.Into after natural water body, make water first
Matter is muddy, and water colour turns yellow, breath malodor.Under microbial action, a large amount of dissolved oxygens (DO) consumed in water body are molten when serious
Solution oxygen is depleted, and organic matter carries out anaerobic digestion, produces various odorants, water body blackening is smelly, water quality deterioration, excrement and urine waste
And its water body, feed and the air polluted, the sprawling and development of livestock and poultry infectious disease and parasitic ovum are eventually resulted in, influences domestic animal
Poultry and human health, continuing, developing in a healthy way for scale livestock rearing industry itself is also threaten, the vicious circle of this pollution is given
The development of poultry industry causes serious harm.
Utility model content
The purpose of this utility model is：A kind of cultivation excrement dirt reutilization system is proposed, it is dirty using livestock and poultry cultivation fecaluria
Aquatic production biogas, not only can be with pollution abatement, and can obtain a large amount of regenerative resources --- biogas, be advantageous to plant's section
Energy emission reduction and comprehensive utilization of resources, and can be with pollution administration, condition of improving environmental sanitation, reduce disease incident.
To solve the above problems, the utility model employs following technical scheme：
One kind cultivation excrement dirt reutilization system, including be sequentially communicated mixing preparation pond, hydrolysis acidification pool, it is described mixing adjust
Connected with pond with excrement dirt source；The hydrolysis acidification pool is connected by elevator pump with CSTR anaerobic reactors；The CSTR anaerobism
Reactor is connected with biogas residue-biogas liquid pool；The CSTR anaerobic reactors are also communicated with wet storage holder.Produced to improve biogas
Rate, temperature is preferably kept in 20 DEG C~35 DEG C in CSTR anaerobic reactors.
Preferably, the biogas residue-biogas liquid pool is communicated to mixing preparation pond by biogas slurry reflux pump.
Contain the suspended material such as a large amount of residual feeds and feed package thing residue in piggery wastewater, and these suspensions hold very much
Easily cause equipment and line clogging, such as handle not in time, may finally cause whole processing system can not normal work.To solve
This problem, it is also associated with being provided with grid machine in grid canal grid canal between the excrement dirt source and mixing preparation pond.So that poultry
Poultry manure sewage is first discharged into grid canal, gets rid of substantial amounts of suspension by grid maker, then enters back into mixing preparation pond.
For ease of further being used caused biogas, between the CSTR anaerobic reactors and wet storage holder
Also it is sequentially communicated moisture trap and desulfurizing tower.Caused biogas passes through moisture trap, after desulfurizing tower purified treatment, is stored in
In wet storage holder, for supplying and generating electricity.
The biogas that the fuel that the system uses produces for system itself, without extra fuel.Utilize the waste heat of marsh gas power generation
Available for heating CSTR anaerobic reactors.The CSTR anaerobic reactors can be connected methane boiler.Methane boiler can be used as standby
With heat resource equipment and emergent burner.
Biogas to be produced using the system is generated electricity, and the wet storage holder can be connected with generating set.
The CSTR anaerobic reactors that the system uses are a kind of new special to handle the larger reaction of solid contents
Device, its construction features are that three phase separator and other components are not set in reactor.Containing high organic solid content (being more than 5%)
Waste liquid is entered by bottom of pond water distribution system, is evenly distributed in the bottom of reactor, and then upper up-flow is by containing high concentration anaerobism
The Solid Bed of microorganism.Make organic solid in waste liquid and the abundant haptoreaction of anaerobe, organic solid is liquefied fermentation
And anaerobic digestion, the organic matter that there are about 50% or so are converted into biogas.And caused biogas has stirring mixed with current rising
Cooperation is used, and promotes contact of the solid with microorganism.Because there is a natural sedimentation effect in Action of Gravity Field Solid Bed area, proportion is larger
Solids (including microorganism, undegradable solid and inoganic solids etc.) is accumulated in Solid Bed bottom, makes to keep in reactor
Higher amount of solid and biomass, reactor can be made to have longer microorganism and solid retention time.Pass through the current of Solid Bed
Outside Chi Ding outlet canal overflow to pond.Slag trap is set before water outlet overflow canal, the loss of suspension in pond can be reduced, anti-
Device liquid level is answered to form one layer of scum layer, in running steady in a long-term, scum layer tends to be dynamically flat after reaching certain thickness
Weighing apparatus.Constantly there is solid to be carried to scum layer by biogas, while also there is degassed solid to return to Solid Bed area.Because biogas will
The collection chamber of reactor head is entered through scum layer, certain " broken " effect is produced to scum layer.It is anti-for productivity
Answering device, scum layer will not cause blocking because scum silica frost surface layer is larger.Biogas in collection chamber is drawn through conduit to be entered outside pond
Biogas storage cabinet.Reaction tank set discharge pipeline can by unnecessary sludge and under sink to the inert substance of bottom and periodically exclude.
Biogas residue caused by the system can be used as Raw material processing production organic fertilizer.Biogas slurry can be used for applying fertilizer or making fertilizer.
Cultivation excrement dirt reutilization system provided by the utility model not only may be used using livestock and poultry cultivation excrement and urine waste production biogas
With pollution abatement, and a large amount of regenerative resource-biogas can be obtained, can be used as fertilizer with caused biogas residue, biogas slurry, and
And the biogas that the fuel used in technical solutions of the utility model produces for system itself, without extra fuel.Be advantageous to cultivate
Field energy-saving and emission-reduction and comprehensive utilization of resources, and can be with pollution administration, condition of improving environmental sanitation, reduce disease incident.
