Description
Technical field
The present invention relates to a kind of breeding wastewater energy self-circulation treatment system and method thereof.
Background technology
Nearly more than 30 years, especially since the nineties, the animal husbandry development of China is rapid, meat and the birds, beasts and eggs output of current China all leap to No. 1 in the world. and modernization case type large-scale cultivation technology facilitates the livestock and poultry breeding industry in China city to high-quality and efficient development, but then, also make livestock and poultry breeding industry depart from traditional kind and grow industry, become highly-specialised to produce, a large amount of waste water of livestock and poultry farm discharge, mostly without properly reclaiming profit and process, dispose and namely directly discharge, organism contained in its water, the dissolved oxygen in water is consumed rapidly after entering water body, cause water hypoxia and affect the existence of fish and other aquatic animals and plants, in waste water, suspended substance easily under anaerobic decomposes generation foul smell simultaneously, worsen water quality.Some city livestock and poultry breeding industry pollution loading amount has exceeded the summation of the pollution load of trade effluent and sanitary sewage, and wherein the pollution load of Wastewater from Pig Farm accounts for major part.
The sewage of plant can be carried out certain process by building cultivating wastewater purification project, the environment of plant being had greatly improved simultaneously, also significantly reduces the pollution to surrounding environment, meeting the requirement of local environment protection.Therefore the construction of cultivating wastewater purification project is all very significant from economic benefit, environmental benefit or social benefit.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of breeding wastewater energy self-circulation treatment system and method thereof, this treatment system and treatment process can get rid of the objectionable impurities in breeding wastewater preferably, discharged breeding wastewater is up to state standards, alleviate environmental pollution, the fertilizer produced in treating processes can be used for agricultural planting, reduces costs.
For solving the problem, the present invention adopts following technical scheme:
A kind of breeding wastewater energy self-circulation treatment system, comprise filtering grid, settling pit, solid-liquid separation tank, large-sized biogas anaerobic pond, ammonia-nitrogen stripping tower, two sections of A-O reaction tanks, sludge sump, biogas purifier and biogas generators, described filtering grid, settling pit, solid-liquid separation tank, large-sized biogas anaerobic pond, ammonia-nitrogen stripping tower are connected according to this with two sections of A-O reaction tanks, described pair of section A-O reaction tank connects described sludge sump, described large-sized biogas anaerobic pond connects described biogas purifier, and described biogas purifier connects described biogas generator.
Filtering grid
Filtering grid is the conventional pre-processing device in engineering of water treatment; it can tackle the coarse particles impurity in the waste water such as larger foreign material, plastics bag; to protect the steady running of subsequent disposal operation, from the foreign material that grid clears, availablely manually cleared up outward transport.
Solid-liquid separation tank
Utilize solid-liquid separating machine the solid sundries such as excrement slag, food-residue, hair in sewage to be separated, clear liquid then flows into large-scale film anaerobic biogas generating pit; Excrement slags etc. are then as fertilizer.
Large-sized biogas anaerobic pond
Large-sized biogas anaerobic pond does housing for adopting mould material, improves inside and arranges water-distributing device, interior whipping appts, heating system, improve biogas fermentation effect, and have biogas storage function.This structure has raising biogas fermentation efficiency and the feature to the continual and steady air feed of biogas generator.
Large-sized biogas anaerobic pond is a kind of anaerobic digestion process of Sludge Bed growth form.Be made up of water inlet water distribution system, reaction zone, settling region, solid-liquid separation, gas storage system, spoil disposal and outlet system.In reaction zone, bottom, retain a large amount of anaerobic sludge, the mud with good sedimentation function and cohesion performance forms sludge blanket in bottom.Sewage to be processed carries out mixing from the inflow of anaerobic mud bed bottom with mud sludge blanket and contacts, and the organism in the microbial decomposition sewage in mud, is converted into biogas it.Biogas is constantly released with micro-bubble form, micro-bubble is in uphill process, continuous merging, form larger bubble gradually, be separated because the stirring of biogas forms sludge concentration thinner mud with water together rising reaction tank top on Sludge Bed top, biogas is stored in reaction tank top after being separated.Fall to again after mud natural separation at the bottom of reaction tank with newly enter sewage and mix, then carry out biogas fermentation reaction.Unnecessary mud is then discharged by shore pipe and is done fertilizer.
Adopt large-sized biogas anaerobic pond, the COD of 1g, under the degradable condition of anaerobic reactor, can produce the biogas (CH4) of 0.25g, be equivalent to the biogas 0.40L under standard state.Biogas is a kind of well gaseous fuel, and thermal value is 20000 ~ 23000kJ/m3 biogas.The COD that the biogas recycling that anaerobic technique removal COD produces often removes 1kg can produce 0.4 ~ 0.5 cube of biogas, and every cube of biogas can obtain the economic benefit of 2 degree of biogas electricity by marsh gas power generation, and each power unit of the system that can be provides electric power energy.
Marsh gas purifying adopts low pressure desulfurization and high pressure dehydration technique, improves the heat of burning, eliminates pollution and the corrosion of hydrogen sulfide simultaneously.Whole system can realize adjustable constant voltage air feed, easily controls, easy to use, use gas effect stability.
Ammonia-nitrogen stripping tower
Ammonia-nitrogen stripping tower is for utilizing air and ammonia nitrogen in sewage concentration difference, by ammonia nitrogen by transferring in gas in sewage, ammonia in gas absorbs by recycling acid, so repeatedly can by sewage the ammonia nitrogen overwhelming majority remove, by improving stripping tower inner structure and filler, ammonia nitrogen in sewage can be improved to air transfer efficiency and speed.Thus effectively eliminate ammonia nitrogen in sewage and reduce energy consumption and produce nitrogenous fertilizer.
Two sections of A-O reaction tanks
Two sections of A-O reaction tanks are the abbreviation of two section anaerobic-aerobic biochemical processing process, anoxic biochemical treatment section has denitrification, mineralized nitrogen in sewage can be become free of contamination nitrogen to discharge water body, aerobic section then can well COD in degradation of sewage, thus A-O combination can the effectively ammonia nitrogen of remnants and COD in degradation of sewage.By local improvement cloth water structure and pond body structure ratio, improve mud and sewage mix contact efficiency and oxygen supplies, and adopt segmentation structure, thus effectively improve the removal effect of ammonia nitrogen and COD, ensure that the decontamination effect improving of sewage.Reach emission standard.
A kind of breeding wastewater energy self-circulation treatment process, comprises the following steps:
1) breeding wastewater enters in settling pit by filtering grid, the coarse particles impurity in the breeding wastewaters such as larger foreign material, plastics bag is tackled by filtering grid, breeding wastewater after having filtered enters settling pit, and the coarse particles impurity be blocked is by manually carrying out cleaning outward transport;
2) breeding wastewater is after settling pit precipitation, pumps to solid-liquid separation tank, carry out solid-liquid separation by solid-liquid separation tank by water pump, and clear liquid flows into large-sized biogas anaerobic pond and carries out biogas fermentation process, and solid then processes as fertilizer;
