Description
Technical field
The invention belongs to field of Environment Protection, and in particular to a kind of innoxious cyclic utilization system of livestock breeding biogas slurry.
Background technology
Livestock and poultry cultivation is specialized to concentrate feeding manner with scale, is conducive to improving breeding technology, pest resistance and management
Level, compared with traditional approach is peasant household's dispersion raising, large-scale breeding is greatly improved production efficiency and feed conversion rate, drop
Low production cost, increases economic benefit.But livestock and poultry large-scale breeding also results in fecaluria concentrations and flushing water substantial increase, gives
Ecological environment brings enormous pressure.It is traditional and cost-effective method of disposal that swine manure wastewater returning to the field, which makees fertilizer, can make poultry
Brid guano urine is not discharged into external environment, reaches zero release of pollutant.Both pollutant can be effectively disposed, again can be by wherein useful nutrition
Composition is circulated in soil-plant ecosystem.The pattern is applied to away from city, soil is broad and has enough farmlands to dissolve
The area of fecal sewage is, it is necessary to the corresponding transmission pipeline network of auxiliary construction.And the conventional transmission pipeline network of China is generally " main pipe at present
The pattern of+branch pipe ", not only operates inconvenience, and anti-blockage capability is poor, often runs after 3-5, because local main is damaged or pipe
Road blocks and causes whole transmission pipeline network to be paralysed.In addition with the extensive use of natural pond fertilizer, natural pond fertilizer pollution problem also increasingly causes
The attention of people.It is many place during scale animal and poultry cultivation, for accelerate growth of animals or poultry speed, improve efficiency of feed utilization and
Livestock and poultry is prevented, it is a large amount of in feed addictive to use trace element in copper, zinc, iron, arsenic etc..Many studies have shown that, feed
Middle addition copper has obvious growth promoting function to pig each stage.At present, in the pig-breeding of China and other countries, height is used
Dosage copper is fairly common as the feed additive for promoting growth of pig, but the biological value of heavy metal element in animal body is very
It is low, it is most of to be excreted with feces of livestock and poultry, therefore the often heavy metal containing a large amount in feces of livestock and poultry, so as to add agricultural poultry
The risk of poultry manure pollution environment.
The content of the invention
It is an object of the invention to overcome prior art pipeline easily to block, Heavy-metal Polluted Environment in feces of livestock and poultry lacks
Fall into effectively prevents line clogging, the innoxious cyclic utilization system of the livestock breeding biogas slurry of reduction soil pollution there is provided a kind of.
The purpose of the present invention is achieved through the following technical solutions：
The innoxious cyclic utilization system of the livestock breeding biogas slurry of the present invention, by biogas slurry innocuity disposal system and spray irrigation system group
Into, it is characterised in that biogas slurry innocuity disposal system is made up of sedimentation basin, processing pond and liquid storage tank, and swine manure wastewater enters heavy
Shallow lake pond, the supernatant overflow of sedimentation basin enters in processing pond, processing pond added with lime, and the biogas slurry in processing pond enters liquid storage tank；
Spray irrigation system is made up of biogas slurry pond 1, pipeline 2, shower nozzle 3, backwash pump 4 and gate valve 6, and the biogas slurry in liquid storage tank is entered by water pump
Enter in the biogas slurry pond 1 applied and filled in field 8, biogas slurry pond 1 and be provided with water pump, exit of pump is connected by check-valves 5 and pipeline 2, pipe
Shower nozzle 3 is provided with the formation of road 2 looping network, looping network, and has return pipe 7 all the way, outlet and the biogas slurry pond 1 of return pipe 7
Connection；Backwash pump 4 is connected by gate valve 6 with looping network.
The workflow of the present invention is as follows：
Swine manure wastewater is precipitated into sedimentation basin, and supernatant overflow enters processing pond.Added with lime in processing pond, regulation
PH value is in alkalescent, and heavy metal is carried out into precipitation removal, biogas slurry harmless treatment is realized.Biogas slurry after harmless treatment enters
Liquid storage tank, is entered by water pump and applies the biogas slurry pond filled in field, during pouring, opens the water pump in biogas slurry pond, and biogas slurry enters ring-type
Pipe network, and field is poured by shower nozzle.Fraction biogas slurry is back in biogas slurry pond by return pipe.Wait after the completion of pouring, close
Water pump in biogas slurry pond, opens gate valve and backwash pump, when having clear water outflow in return pipe, shows that biogas slurry has been rushed in pipeline
Wash clean, now closes backwash pump, gate valve successively.
The beneficial effects of the present invention are：
（1）The harmful components in biogas slurry are effectively removed, soil pollution is reduced.
Pass through biogas slurry innocuity disposal system, it is possible to decrease content of beary metal in biogas slurry, slow down to Soil Environmental Pollution.And warp
Cross after two-stage precipitation, solid matter content in biogas slurry can be substantially reduced, prevent from resulting in blockage to pump and conveyance conduit.
（2）Biogas slurry irrigation automation is easy to implement, human input is reduced.
General branch network of pipes is before sprinkling irrigation, in order to prevent water pump from occurring being suppressed situation about stopping, it is necessary to first by specified shower nozzle
Open, be then then turned on elevator pump.If irrigated area is larger, need manually to come and go back and forth.The loop pipe that the present invention is designed
Net, biogas slurry can be filled after being lifted via elevator pump in any pipeline section of pipe network, and has fraction biogas slurry to be back in biogas slurry pond.Therefore
After elevator pump is opened, any one shower nozzle that just can arbitrarily open, close in pipe network can be operated completion by a people.
（3）Increase pipe network stability, extend pipeline service life.
Because branch network of pipes is single pipeline section, therefore in the case that blocking, fracture occur for a certain node, after the node
Pipe network can not be further continued for using.The advantage for the looping network that the present invention is set is the stability for greatly increasing pipe network operation,
I.e. when a certain pipeline section goes wrong, most of region still can stable operation, provide biogas slurry for region.
（4）Backwashing system is set up, line clogging is prevented.
Biogas slurry is the product of anaerobic fermentation, containing substantial amounts of suspended particulate substance, after spray irrigation system is out of service, is rested on
Particulate matter in pipeline in biogas slurry starts after deposition, long-play, in-service pipeline will be caused to block.For above-mentioned situation,
Backwashing system is devised, periodically clear water is pumped into pipe network using backwash pump, original biogas slurry is rinsed out, prevents particulate matter
Deposition, causes line clogging.
In addition, branch network of pipes also needs to open the shower nozzle of each branch section pipe network end, this section of pipe network can just be cleaned.And
The present invention uses looping network, therefore starts after backwash pump, and without opening each shower nozzle, clear water just can enter biogas slurry pond
In, every section of pipe network can be cleaned, easy to operate, be saved labour turnover.
Therefore, easily block instant invention overcomes prior art pipeline, the defect of the Heavy-metal Polluted Environment in feces of livestock and poultry,
The innoxious cyclic utilization system of livestock breeding biogas slurry of offer is effectively prevented line clogging, reduces soil pollution.
