Description
Technical field
The present invention relates to agriculture nitrogen, phosphorus field of surface source pollution control technology, more particularly to a kind of farmland nitrogen and phosphorus recovery device.
Background technology
The rainwash that natural rainfall and unsuitable irrigation are formed, farmland nitrogen, phosphorus transfer are brought into surface water body,
Cause a large amount of losses of Soil Nitrogen, phosphorus.Nitrogen that rainwash causes, phosphorus loss are divided into two kinds, one be total soil nitrogen (deposition nitrogen),
The loss of full phosphorus (sedimentary phosphor), two is soil soluble nitrogen (dissolved nitrogen), the loss of titanium pigment (dissolving phosphorus).The annual stream of China
Up to 4,200,000,000 tons, the nutrient such as the nitrogen taken away, phosphorus, potassium is approximately equivalent to the whole nation chemical fertilizer application total amount of a year to lost territory earth.Meanwhile, in soil
Nitrogen, phosphorus with agricultural drain, the loss of surface runoff, eventually enter into river water burst body, cause body eutrophication.
The ecological canal of water plant is implanted with using kind, it has been a kind of for carry out interception to the nitrogen in agricultural drain, phosphorus dissolving
More common ecological engineering, i.e. planting aquatic plants in the trench, by absorption, absorb, precipitation, filtering and microbial degradation etc.
Various ways, reach the purpose of part nitrogen and phosphorus pollution thing in draining of dissolving in situ.But, this kind of method can not be realized to farmland
The nitrogen of middle loss, phosphorus are recycled.
The content of the invention
The purpose of the present invention is directed to the above-mentioned shortcoming that existing agriculture nitrogen, phosphorus non-point source pollution control technique are present, there is provided
A kind of farmland nitrogen and phosphorus recovery device, to solve the problems, such as that the nitrogen being lost in farmland, phosphorus cannot be recycled.
To achieve the above object, the invention provides a kind of farmland nitrogen and phosphorus recovery device.The device is provided with base plate
Mobilizable first baffle and second baffle, first baffle and second baffle are staggered relatively；Between first baffle and second baffle
It is provided with multiple filtering sponges；First baffle is provided with respect to the one side of second baffle and is arranged with multiple filtering sponge quantity identical
Water hole；Drainpipe is provided with first baffle, drainpipe connection osculum is simultaneously connected with outside water pump.
Preferably, when farmland silt and recovery of nitrogen and phosphorus is carried out, second baffle and filtering sponge were fallen, from first baffle
In osculum water outlet washing and filtering sponge in farmland silt and nitrogen phosphorus.
Preferably, first baffle can be inclined 10 degree of settings.
Preferably, the device also includes cistern, and the moisture in filtering sponge will be flowed into cistern.
Preferably, the device also includes solar panel, for being powered to the device.
Preferably, the PPI indexes of filtering sponge are more than 50.
The present invention provide a kind of farmland nitrogen and phosphorus recovery device, using filter sponge absorption agricultural drain and agricultural run-off in
Nitrogen, phosphorus, effectively intercept during nitrogen, phosphorus flow into river water burst body and cause body eutrophication, and realize the recovery profit to nitrogen, phosphorus
With.

Specific embodiment
Below by drawings and Examples, technical scheme is described in further detail.
Fig. 1 is a kind of structural representation of farmland nitrogen and phosphorus recovery device provided in an embodiment of the present invention.The device is in base plate 3
On be provided with mobilizable first baffle 1 and second baffle 2, first baffle 1 and second baffle 2 are staggered relatively；In first baffle 1
Multiple filtering sponges 5 are provided with and between second baffle 2, first baffle 1 is provided with respect to the one side of second baffle 2 and is filtered with multiple
The quantity identical osculum 6 of sponge 5；Be provided with drainpipe 7 in the first baffle 1, the connection osculum 6 of drainpipe 7 and with it is outer
The water pump 8 in portion.
Specifically, the device that the present embodiment is provided is placed at agricultural run-off, when rainy, rain drop erosion Zinc fractions
Runoff, when runoff flows through device, the filtering sponge 5 of the device will adsorb silt and nitrogen phosphorus composition in runoff, while slowing down footpath
Stream flow velocity, so as to reduce with the silt and nitrogen phosphorus composition of Loss in Runoff.Wherein, the PPI indexes of filtering sponge 5 are more than 50.The dress
Putting also includes cistern, and the moisture in filtering sponge 5 will be flowed into cistern.
Fig. 2 is the top view of first baffle in the device shown in Fig. 1；Fig. 3 is that the operation principle of the device shown in Fig. 1 is illustrated
Figure.The device also includes solar panel 9, for being powered to the device.In the field irrigation phase, using the device to filtering sea
Silt and recovery of nitrogen and phosphorus in silk floss are used, and first second baffle 2 fell, and first baffle 1 is inclined to the direction of second baffle 2
Oblique 10 degree of settings, with the filtering sponge 5 that fell.The moisture extracted from cistern by water pump 8 flows through drainpipe 7 and is flowed from osculum 6
Go out, washing and filtering sponge 5.After the silt and nitrogen phosphorus that current will be filtered in sponge 5 are developed, inflow is entered in farmland with to farmland
Row is irrigated.Irrigated using the device after finishing, by the second baffle 2 for being fallen and filtering sponge 5 and inclined first baffle 1
Erect and place, reused to adsorb the silt in agricultural run-off and nitrogen phosphorus composition with when raining next time.
Specific embodiment above, has been carried out further in detail to the purpose of the present invention, technical scheme and beneficial effect
Illustrate, should be understood that and these are only specific embodiment of the invention, the protection model being not intended to limit the present invention
Enclose, all any modification, equivalent substitution and improvements within the spirit and principles in the present invention, done etc. should be included in the present invention
Protection domain within.
