Embodiment
Culture pollution source to the distributing duck and disperse, pollute the big characteristics of total amount, the present invention can effectively control the distributing duck and culture the recycling that pollutes and realize the duck excrement through source control collection-processing-recycling.
Technical scheme of the present invention is:
1) source emission-reducing system through duck feed addictive, improves feed nitrogen phosphorus absorption ratio, and then reduces duck ight soil nitrogen phosphorus nutrient discharge capacity.
2) duck excrement gathering system is set up the collection mode of corresponding duck excrement to the land-based activity zone of duck, like screen cloth collection, pipeline collection, irrigation canals and ditches collection etc.
3) processing and resource system, the duck excrement waste water of land collection adopts biogas fermentation+land treatment system, and dried duck excrement is handled through compost+vermiculture.The ecological intercepting system handles of duck water surface behaviour area through making up by water plants and animal.Wherein, biogas can be used as the energy, and liquid natural pond, natural pond slag is as vegetable plot, reed ground fertilizer and water surface behaviour area fish meal; Earthworm can be used as the feed of duck and fish, and the duck excrement after earthworm is handled also can be used as fertilizer.
Below in conjunction with embodiment and accompanying drawing the present invention is done detailed explanation.
Embodiment:
Distributing duck breed pollution control and method of resource are applied to zone, Baiyang Lake, Anxin County, Baoding, Hebei province distributing duck plant.This plant is positioned at Wang Jiazhai village, town, Anxin, Anxin County, Baoding, Hebei province.Plant's situation is as shown in Figure 1, and this plant is the typical ait duck aquaculture model in zone, Baiyang Lake, and about 5000 square metres of whole ait area has one of kind of duck plant, and the breed scale is 1500.Produce about 54 tons of duck excrement per year, do not have and deal carefully with facility, the duck excrement directly pours water body, and is seriously polluted.Resident one family is arranged on the island, do not have corresponding sanitary installation.This island can be divided into parts such as house 1, warehouse 2, duck canopy 3, brick district 4, duck water surface behaviour area 5, face behaviour area, duck land 6, reed field 7.
Plan that according to the present invention back duck plant plane is as shown in Figure 2, the distributing duck that carries out according to method of the present invention in this plant is cultured the pollution control technology engineering design and mainly contains the following aspects:
It at first is the structure of source pollution reduction system.In the duck feed, be added on the sodium butyrate that adds 0.03%-0.05% in the duck feed, require sodium butyrate and feed to mix the back and use, can improve the absorption ratio of duck, reduce the discharging of N, P N, P.
Next is duck excrement and wastewater collection system.Adopt corresponding duck excrement and wastewater collection mode according to the zone of action of duck.For the Ya Peng district, dried duck excrement collects through hand sweeping; The duck excrement in brick district 4 and duck excrement waste water adopt collects irrigation canals and ditches (pipeline) 16 collections, and the irrigation canals and ditches effective width is 25-50cm, and the degree of depth is 30-60cm, and length runs through whole brick district; Duck land-based activity district adopts screen cloth to collect duck excrement, the long 20m of screen cloth, wide 17m.
The 3rd is duck excrement Waste Water Treatment.Treatment system is made up of duck excrement wastewater collection pond 9, marsh gas fermentation pool 8, sedimentation basin 11, land treatment system 10.The duck excrement waste water of collecting gets into collecting pit, and through getting into sedimentation basin behind the biogas fermentation, the water outlet of post precipitation is through artificial wet land system, can effectively remove in the water outlet organic matter and nitrogen phosphorus, finally get into the reed field.Collecting pit is of a size of 2m*2m*1m; Marsh gas fermentation pool is according to 15m in " GBT 4750-2002 user biogas generating pit standard collective drawings "
3The construction of capacity; Sedimentation basin is 2m*2m*1m; Land treatment system 10 is a drowned flow artificial wet land, is of a size of 4m*4m*1.2m.Be horizontally disposed with water distributor apart from drowned flow artificial wet land upper surface 20～50cm place, caliber is 100mm, and downside has through hole, and water distributor is positioned at the wetland upper reaches, the lateral direction penetrating drowned flow artificial wet land; Collector pipe is established in drowned flow artificial wet land downstream bottoms, caliber 100mm, and upside has through hole, the lateral direction penetrating drowned flow artificial wet land, and collector pipe one end stretches out drowned flow artificial wet land and communicates with sump, in the water outlet entering sump.Its filler is by gravel, rubble, and coarse sand, wood chip, land plaster, artificial soil one of them or several kinds mix.The vegetation on wetland surface is reed.
The 4th is dried duck excrement disposal system.This system is made up of compost pond 12, earthworm and ecological bed 13.The dried duck excrement of collecting gets into the compost pond, through adding conditioner (zeolite powder+reed straw), reduces the carbon nitrogen loss in the composting process, is used for vermiculture after treatment.The conditioner proportioning is that duck excrement per ton adds 40～100kg stalk and 45～60kg zeolite powder.Totally 3 in compost pond is of a size of 1m*1m*1m.6 of earthworm and ecological beds are of a size of 0.5m*0.3m.The earthworm of culturing can be used as duck foodstuff and fertilizer.
The 5th is ecological intercepting district, duck water surface behaviour area 14.Duck water surface behaviour area is provided with the screen cloth system 15 that is formed by purse seine, water plants such as configuration water lily, water caltrop, and culture grass carp, crucian, carp etc.Water plants and the animal duck excrement of can dissolving.Liquid natural pond, natural pond slag can be applied to vegetable plot 17 as fertilizer, and plant can be used as bait and the biogas generating pit raw material of fish simultaneously, and fish culture can bring economic benefit.
This plant's direct discharge capacity of duck excrement is 14.44 tons/year (calculating by 1500 ducks), and N, P discharge capacity are respectively 0.76 ton/year, 0.20 ton/year.Support duck with tradition and compare, N, P reduction rate can reach 67%, 61% respectively, and N, P discharge capacity have reduced about 59%-64%, 59%-65% respectively.The biogas that biogas generating pit produces can satisfy basically the islander illumination, cook and warm oneself, can save about 1500 yuan every year, alleviate the household economy burden.This prevention and control engineering had both been improved the breed hygienic conditions, also helped peasant household to reduce feed and fertilizer input, produced certain economic benefits, had realized the trans-utilization of resource.
