Technical field
The present invention relates to technical field of sewage more particularly to a kind of cultivating farm sewage treatment methods.
Background technology
Sewage of farm includes mainly animals urine, Some Animals excrement and breeding house flushing water, belongs to the organic dirt of high concentration
Water, and suspended matter and ammonia-nitrogen content are big.After this raw sewerage enters natural water, make solid suspension in water,
Organic matter and content of microorganisms increase, and change physics, chemistry and the biocoene composition of water body, water quality is made to degenerate.In sewage also
It will be diffused propagation by water body or by aquatic animals and plants containing a large amount of pathogenic microorganism, and endanger human and livestock health.In order to
The three for accomplishing economic benefit, social benefit and environmental benefit organically combines, and so that enterprise is walked the road of sustainable development, it is necessary to right
Its sewage is effectively administered.
Through retrieval, Chinese patent Authorization Notice No. is that CN107285469A discloses a kind of monomer piggery waste water process side
Method includes the farm for aquaculture wastewater being dissolved or being unable to completely full ecological consumption without ecology, with each pig farm for one
A separate unit, sewage treatment facility is for each individual raiser.The small, sewage quantity according to single farm's floor space
The characteristics of few, but organic concentration is high, nitrogen and phosphorus content is high and contains bulky stool slag, select " cleaning up excrement+integrated equipment for wastewater treatment+change
Handle " technique.The excrement of cleaning enters fish pond or compost, and sewage disposal is filled with anaerobic- anoxic- oxic integrated sewage disposal
Be set to master, in conjunction with company's independent research to livestock and poultry cultivation wastewater pollutants have the denitrogenation dephosphorizing engineering bacteria that efficient degradation acts on into
Row denitrogenation dephosphorizing is aided with flocculation sediment or disinfection, and water outlet is for irrigation or reuse, the processing livestock and poultry sewage being simple and efficient.
Existing sewage water treatment method has the following disadvantages：It is had ignored except in decontaminated water in traditional wastewater processing method
A small amount of heavy metal ion so that the water after processed cannot be used for the agricultural uses such as irrigation, and conventional method energy consumption is big, with
The economic benefit of harvest is not directly proportional.
Invention content
The purpose of the present invention is to provide a kind of cultivating farm sewage treatment method, have that low energy consumption, scavenging effect is good, can
It the advantages of a small amount of heavy metal ion in removal sewage, processed sewage can be used in agricultural irrigation, solves at traditional wastewater
Reason method is ignored except heavy metal ion a small amount of in decontaminated water so that and the water after processed cannot be used for the agricultural uses such as irrigation,
And conventional method energy consumption is big, the problem not directly proportional to the economic benefit of harvest.
A kind of cultivating farm sewage treatment method according to the ... of the embodiment of the present invention, S1：The waste water of farm is passed through into blow-off pipe
It is emitted into sieving pond, 80-120 mesh stainless steel mesh is selected tentatively to be filtered, bulky grain is removed and fixes impurity；

Waste water is passed through the tune that water quality and quantity is carried out in regulating reservoir by metal ion calcium ion, magnesium ion, barium ions, lead ion after filtering
Section, the time that waste water is controlled in pond are 10-20 hours；
S3：After reaching the residence time, waste water is passed through in UASB anaerobic ponds, anaerobic pond is added into UASB anaerobic ponds and is filled out
Material, while UASB anaerobic ponds are heated to 200-300 DEG C；It is passed into sbr reactor pond after processed and carries out Anoxic/Aerobic processing,
Processing obtains muddy water mixed solution in 20-30 hours later, is passed into sedimentation basin separated sludge, the sludge isolated is passed to sludge
Concentration basin, and primary water is discharged；
S4：Addition synthesizes organic filler after primary water is passed through denitrification tank, after handling 10-15 hours, is passed into HPQ lifes
State water planting slot stands 1-5 days and obtains water purification for field irrigation.
On the basis of said program, the precipitating reagent includes the raw material of following parts by weight：10-15 parts of sodium carbonate, hydroxide
10-20 parts of sodium, 15-20 parts of sodium sulphate.
On the basis of said program, the anaerobic pond filler is that speed divides biochemistry ball filler, 3 D elastic filler, carbon fiber group
Close one or more mixtures in filler.
On the basis of said program, submersible agitator is set in the sbr reactor pond.
On the basis of said program, it is equipped with air hose in the sbr reactor pond, sbr reactor pond is determined by air blower
Phase air blast, supplemental oxygen.
On the basis of said program, the synthesis organic filler is staple fibre, polyacrylonitrile fibre, nylon fiber, virtue
One or more mixtures in fragrant race's nylon fiber.
The present invention has an advantageous effect in that compared with prior art：
1, large granular impurity can tentatively be removed by stainless steel mesh, preventing it from blocking pipeline influences decontamination, by adding
Enter precipitating reagent can be reacted with the heavy metal ion in sewage such as calcium ion, barium ions, magnesium ion, lead ion generate calcium carbonate,
The flocculent deposits such as barium hydroxide, magnesium hydroxide, lead sulfate are with heavy-metal ion removal；It is a variety of by heating anaerobic pond and addition
The anaerobic pond filler of type can attached microbial, so that anaerobic bacteria is given full play to its effect, shorten Anaerobic Treatment time 10%-
15%；By anaerobism and aerobic combination processing mode relative to only reducing energy consumption 16%-20% by Anaerobic Treatment, and obtain
The water quality obtained is more preferably；By the combination of HPQ ecology water-cultures slot and denitrification tank, the removal rate of ammonia nitrogen can be made to reach 90% or more,
High, the difficult removal problem of breeding wastewater ammonia nitrogen is well solved；
2, treatment effeciency has been further speeded up by the way that submersible agitator is arranged, has shortened processing time 3%-5%, passes through drum
Wind turbine can be to the regular air blast in sbr reactor pond, supplemental oxygen, and synthesis organic filler can accelerate denitrification rates, when saving processing
Between；Low energy consumption by the present invention, and scavenging effect is good, can remove a small amount of heavy metal ion in sewage, and processed sewage can be used in
