Description
Technical field:
The present invention relates to a kind of cultivating wastewater purification device and processing method thereof.
Background technology:
Modernization large-scale cultivation; producing substantial amounts of waste water and excrement is dirty, aquaculture waste water belongs to the high concentrated organic wastewater rich in a large amount of pathogen, is discharged directly into water body or storage place is improper; water body is entered, it would be possible to cause the severe exacerbation of surface water or quality of groundwater by rain-out.Owing to the leaching of Animal fecal pollution is very strong, the leaching such as nitrogen in fecaluria, phosphorus and water soluble organic substance is very big, if do not dealt carefully with, will pass through rainwash and diafiltration enters Water table polluted underground water.On the impact then main manifestations of surface water it is, after large amount of organic matter enters water body, the dissolved oxygen that organic decomposition will consume in water in a large number, make water body smelly；After the dissolved oxygen in water body significantly declines, large amount of organic matter can under anaerobic continue to decompose, and will produce the toxic gas such as methane, hydrogen sulfide, cause aquatile mortality in decomposition；A large amount of float in waste water can make water body muddy, reduces the photosynthesis of algae in water, limits hydrobiological normal activity, making the aquatile to Organic Pollution is sensitive dead gradually, thus being further exacerbated by water bottom anoxia, making water body assimilative capacicy reduce；Nitrogen, phosphorus can make body eutrophication, the result of eutrophication can make NO3-N and NO2-N excessive concentration in water body, if people and animals' long-term drink can cause poisoning, and the growth of some toxic algae and amount reproduction can discharge a large amount of toxin in water body, cause the mortality of aquatic animal, thus seriously destroying water ecology balance；Some pathogenic bacteria, viruses etc. in fecaluria may result in some epiphytotics propagation etc. with water flowing.
Summary of the invention:
It is an object of the invention to provide a kind of cultivating wastewater purification device and processing method thereof.
Above-mentioned purpose is realized by following technical scheme:
A kind of cultivating wastewater purification device, its composition includes: feace storing pool, described feace storing pool is connected with equipment for separating liquid from solid, described equipment for separating liquid from solid is connected with regulating reservoir, described regulating reservoir is connected with hydrolysis acidification pool by water pump, and described hydrolysis acidification pool is connected with UASB reactor, and described UASB reactor is connected with contact-oxidation pool, described contact-oxidation pool is connected with second pond, and described second pond is connected with bio-oxidation pond.

Described cultivating wastewater purification device, described second pond is connected with regulating reservoir.
A kind of processing method of described cultivating wastewater purification device, the method step is as follows:
Flushing water containing a small amount of feces flows into original feace storing pool through being collected from, and then squeezes into equipment for separating liquid from solid (hydraulic screen mesh sheet) with pump, and isolated excrement is delivered to fertilizer Cutter Body Processing with Machining Center and become fertilizer to sell；Isolated waste water, from flowing into regulating reservoir, carries out water quantity and quality adjustment, then squeezes into hydrolysis acidification pool with pump；Under the effect of hydrolysis acidification antibacterial, larger molecular organics is converted into small molecular organic acid, then squeezes into UASB reactor with pump；In UASB reactor, the small organic molecule in waste water reacts with microbiological anaerobic, makes the further chain-scission degradation of small organic molecule, and the biogas produced in this process enters gas storage holder for generating etc. after dehydration desulfurization processes；The waste water discharged by UASB reactor, from flowing into contact-oxidation pool, fully reacts with the aerobic microbiological in pond, aerobic-anaerobic microbe and a small amount of anaerobe, makes the Organic substance in waste water inorganization further；Waste water after reaction fully is from flowing into second pond, and Gravity Separation under the effects such as gravity, sludge reflux is to regulating reservoir by the further stabilized treatment of front-end-of-line, and supernatant, from flowing into bio-oxidation pond, carries out further materialization and biological treatment purifies；The water of bio-oxidation pond finally flows into artificial swamp, obtains fully degraded further under the effect of the root systems of plant such as phragmites communis and ambient microorganisms, and waste water is qualified discharge or irrigated farmland after artificial wetland treatment.
Beneficial effects of the present invention:
The anaerobic treatment method that the hydrolysis acidification that the present invention adopts combines with UASB response system, it it is the treatment technology grown up in theory in biphase and heterogeneous anaerobic digestion, diphasic anaerobic processes and different dominant bacterias is grown in different reactor environment, so be conducive to growth and breeding and the metabolism of various different microorganisms, improve the biological activity of microorganism, reduce the mutual inhibitory action because competition and antagonism bring.
The present invention adopts UASB reactor not only floor space to be greatly reduced, and treatment effeciency is greatly improved, and UASB reactor creates its high treatment efficiency and the feature of high yield gas rate with the comprehensive function of its special structure and granule sludge therein.
The water outlet of UASB is done Aerobic Process for Treatment and be ensure that the further optimization of waste water quality by the present invention, and contact oxidation method determines its high treatment efficiency, stable treatment effect and low mud production rate with its high sludge concentration, the ecosystem of stepped height, longer food chain etc..
Present system adopts bio-oxidation pond that contact-oxidation pool water outlet is further processed, and so not only takes full advantage of original discarded cell body, and waste water can carry out again materialization and biological processes；Utilize the artificial swamp that original useless pool is transformed that waste water has done deeper process, be not only advantageous to discharged wastewater met the national standard and be back to farmland and pig house washing water, the raw materials of industry such as phragmites communis can also be produced simultaneously
UASB reactor of the present invention is provided with circulating pump, starts when variation water quality is big, improves up-flow speed, is beneficial to reactor mud and is in high level expansion state, increase the contact area of mud and waste water, reduce the impact that system is brought by variation water quality, improves reaction efficiency；The mud continuous backflow of second pond, in regulating reservoir, is conducive to denitrogenation dephosphorizing；The mud that whole system produces regularly is discharged to the phragmites communis in neighbouring farmland, artificial swamp as fertilizer by UASB reactor and regularly gathers in sale.
