Description

The raise pigs treatment system of waste water of a kind of distributing
Technical field
The utility model relates to technical field of waste water processing, especially relates to the raise pigs treatment system of waste water of a kind of distributing.
Background technology
The distributing pig of raising scattered that waste water refers to that scale is less of raising pigs is raised on a household basis pig waste water, pig house is located in peasant household's garden, its cultivation scale is below 2000, owing to lacking economically viable treatment technology, in a large number enter surface water body without the dispersions of effectively the processing waste water of raising pigs, cause larger pollution, become the problem of needing solution in Process of New Countryside Construction badly, existing large-scale cultivation wastewater processing technology energy consumption is large, operational management cost is high, be not suitable for and disperse and the wastewater treatment of raising pigs on a small scale, in the urgent need to for disperseing and the waste water of raising pigs on a small scale, seek a kind of cost-effective suitability water technology, especially can effectively remove nitrogen in waste water, the treatment process of phosphorus, carry out Typical Rural dispersion and breeding wastewater pollutent source reduction of discharging on a small scale, the research of biological and ecological coupling degradation of organic substances and nutritive element and pollutant resources integrated technology, solve water body nitrogen, phosphorus pollutes, meet to greatest extent environment sustainable development requirement
Summary of the invention
The utility model is for the raise pigs feature of waste water of rural area distributing, in conjunction with the practical situation of rural economy ability, and the concrete physical environment in Rural areas, suit measures to local conditions, research and development are applicable to rural area distributing raise pigs new technology and the novel process of wastewater treatment, provide one to there is low investment, less energy-consumption, low operational administrative requirement, and the raise pigs treatment system of waste water of the distributing with stability and high efficiency contaminant removal capacity.
To achieve these goals, the utility model is by the following technical solutions: the raise pigs treatment system of waste water of a kind of distributing, comprise pig manure waste water pretreatment system, solid pig manure utilization system, pig manure urine innocuity disposal system, described pig manure waste water pretreatment system comprises mud extrusion machine or centrigugal swing dryer, described solid pig manure utilization system comprises fermentation vat, described pig manure urine innocuity disposal system comprises liquid separating appts, liquid cleaning device, described pig manure waste water pretreatment system respectively with solid pig manure utilization system, pig manure urine innocuity disposal system is communicated with.Pig manure and pig manure urine are carried out source separation by this programme, utilize mud extrusion machine or centrigugal swing dryer to drain after processing pig manure, the solid pig manure that stays enters fermentation vat, fermentation vat can adopt existing methane-generating pit, in pond, obtain organic fertilizer or carry out marsh gas power generation for peasant household through biological fermentation bed processing, and primary pollution source pig manure urine is taked to liquid liquid isolation technique, pig manure urine is separated with wash-down water, then pig manure urine is carried out to deep layer purifying treatment, isolated wash-down water is sterile-processed, such as reuse after lime disinfection to ight soil rinses, final waste water is treated discharges after reaching GB emission standard.
As preferably, described liquid separating appts comprises organic membrane.Utilize special organic molecular film to carry out the separation of liquid liquid in the pig manure urine containing wash-down water, after separating containing the less wash-down water of the organic compositions such as ammonia nitrogen, it is remaining that to deal with quantity containing the more pig manure urine of the organic compositions such as ammonia nitrogen just relatively less, alleviate the intensity of processing, improved overall treatment efficiency.
As preferably, described fermentation vat comprises padding layer.Add one deck padding layer at existing fermentation vat in such as swine waste marsh gas pond, this padding layer is fermentation bedding and padding, fermentation bedding and padding are generally made up of maize straw, bagasse or stalk, vinasse, sugar grain etc., can be used as the agricultural fertilizer of special efficacy by the fermentation residue after the fermentation of solid pig manure utilization system.
As preferably, described liquid cleaning device comprises ammonia nitrogen removal device and dephosphorization treatment unit.More containing the organic compositions such as ammonia nitrogen and phosphorus composition in pig manure urine, the two is all also the fertilizer component that can again utilize, utilize ammonia nitrogen removal device and dephosphorization treatment unit that ammonia nitrogen organic composition and phosphorus composition in pig manure urine are separated, remaining liquid can be sterilized, such as reclaiming the reuse water of making to rinse pig manure urine after lime disinfection.
As preferably, described liquid cleaning device comprises artificial swamp filtering layer.Utilize filtering layer that liquid is after treatment filtered again, adsorbable, the impurity of precipitation in liquid, further promotes water quality, and artificial swamp filtering layer can be made with industrial residues such as slag, cinder, cinders.
Therefore, the utlity model has following beneficial effect: (1) low investment, less energy-consumption, low operational administrative requirement; (2) there is stability and high efficiency contaminant removal capacity.
