Abstract
Provided is an ecological floating bed device for treating livestock and poultry breeding biogas slurry. The ecological floating bed device comprises a water inlet (2), a floating bed carrier (4) and a water outlet (11), wherein a planting basket (6) is embedded in the floating bed carrier (4), an overflow weir (8) is arranged at one water outlet end of the floating bed carrier (4) arranged on the upper portion of the ecological floating bed device. An adsorption tank (10) is arranged under the overflow weir (8). One side of the adsorption tank under the overflow weir is provided with the water outlet (11). As the adsorption tank is arranged under the overflow weir, dissolved oxygen concentration in water is increased through overflow effect. An aerobic reaction can effectively reduce organic pollutant concentration in the water, and pollutant concentration in the water can be further reduced due to utilization of adsorption property of vermiculite or zeolite in the adsorption tank. The water inlet is arranged at the bottom of the ecological floating bed device, and partial organic matter is degraded through the aerobic reaction so that pollution load is reduced and load to plants is lowered. As a whole, the ecological floating bed device is simple and reasonable in structure, and is ideal in treatment of eutrophication waters.
Description
Technical field
The utility model relates to a kind of plant ecological floating bed device that is used for WWT, particularly a kind of ecological floating bed device that is used to handle livestock and poultry cultivation natural pond liquid.
Background technology
The plant floating bed technology that with the higher plant the is main body practical technique that to be a kind of water environment treatment take into account with Ecological Recovery of Water mutually; Its intension is a utilization cultivation technique without soil principle; With the floatability material is matrix or carrier, adopts the water surface hydroponics plant technology of modern agronomy and ecological engineering measure comprehensive integration.Adopt this technology can the high terrestrial plant that can only plant on land originally be planted the natural water area water surface, and can obtain and similar even higher Yield and the landscape effect of land plantation, therefore be applied to administer or repair polluted-water more and more.Because existing ecological floating bed device is primarily aimed at the lower surface water body of eutrophication degree, the livestock and poultry cultivation natural pond liquid processing efficiency higher to organic substance concentration is lower.
The utility model content
The goal of the invention of the utility model is to provide a kind of ecological floating bed device that livestock and poultry cultivation natural pond liquid is handled that is used for.
The goal of the invention of the utility model realizes through following technical measures:
A kind of ecological floating bed device that is used for the liquid processing of livestock and poultry cultivation natural pond; Comprise water-in, floating bed carrier, water outlet; Be inlaid with the plantation basket on the said floating bed carrier; It is characterized in that: floating bed carrier water outlet one end on said floating bed top is provided with overflow weir, and the overflow weir bottom is provided with adsorption tank, and adsorption tank one side is a water outlet.
For thereby the organic loading that reduces eutrophication water reduces the load to plant in the above-mentioned plantation basket, the water-in of said ecological floating bed device is arranged on floating bed bottom.
In order further to improve the ability that the floating bed of plant ecological of the present invention improves water quality, be filled with vermiculite/zeolite (7) in the said plantation basket (6).
In order further to reduce the middle organic concentration of disposing of sewage, to improve processing efficiency, the long 1m of above-mentioned adsorption tank, wide 0.5m, vermiculite/zeolite (preferred 10～20mm) of filling particle diameter 5～50mm; Vermiculite or zeolite filling thickness 50～250mm (preferred 150mm).
The beneficial effect of the utility model is:
(1) owing to is provided with adsorption tank in the overflow weir bottom; Increased oxygen in water concentration through the overflow effect; Support reaction well and more effectively reduced organic contamination substrate concentration in the water, also utilized the adsorption of vermiculite/zeolite in the adsorption tank simultaneously, can further reduce the Pollutant levels in the water.Simultaneously, contain a large amount of phosphorus in the vermiculite/zeolite after the adsorption treatment, make fertilizer after can pulverizing and use, further improved utilization of resources degree.Show that through experimental result vermiculite in the adsorption tank/zeolite phosphorus content can reach 8.5g/Kg.
(2) aerating apparatus that is provided with owing to the utility model ecological floating bed device water-in bottom, waste water gets into biological floating bed district and at first carries out aerobic treatment, decomposes partial organic substances matter, thereby reduces pollution load, reduces the load to plant; Experimental result shows that through aerobic treatment, the waste water COD duty ratio has reduced 15.61.95～23.22.3%.
(3) owing in biological floating bed plantation basket, be filled with vermiculite/zeolite, the carrier that it also adheres to as microbial film in anti-plant lodging has improved floating microbial biomass, has further improved water quality.
(4) the utility model ecological floating bed device simple in structure, ideal treatment effect is set rationally.

Fig. 1 is the work synoptic diagram of the utility model ecological floating bed device.
Embodiment
Below in conjunction with embodiment the utility model is described further, but therefore the utility model is not limited among the following concrete mode.
A kind of ecological floating bed device that is used for the liquid processing of livestock and poultry cultivation natural pond, its planar dimension is 2.0m * 1.5m, available depth 1.2m, useful volume is 3.6 m
3Comprise the water-in 2, floating bed 4, the water outlet 11 that are arranged on floating bed bottom, be inlaid with plantation basket 6 on the said floating bed carrier 4,6 plantations of plantation basket have plant 5 and are filled with vermiculite/zeolite 7 that diameter is 1 cm in it; Floating bed carrier 4 water outlets one end on said floating bed top is provided with overflow weir 8, and overflow weir 8 bottoms are provided with adsorption tank 10, and being filled with particle diameter in the adsorption tank is 5～50mm (vermiculite/zeolite 9 of preferred 10～20mm).
As shown in Figure 1; In the floating bed device that makes up; With water sample with the 1.6L/h flow velocity behind spinner-type flowmeter 1 entering pond; By bottom water-in 2 entering aeration tanks, get into biological floating bed district again through aeration tank upper end, the plant 5 on the floating bed carrier 4 in the plantation basket 6 is that 12 strains drip that (every plant height degree is 30～35cm), each plants basket has four strain plant to kwan-yin with 4 strain common callas; After the floating bed of plant ecological is handled seven days, flow out from overflow weir 8, the bottom adsorption tank 10 of flowing through is handled the back and is discharged floating bed device by water outlet 11.
The floating bed device of above-mentioned structure reaches 76% to the ideal purification effect of total nitrogen total phosphorus in the liquid of livestock and poultry cultivation natural pond to nitrogen removal rate in the eutrophic wastewater, and total tp removal rate reaches 82%.
