Description
Technical field
The utility model is related to detection device technical field, and in particular to a kind of Soil Nitrogen leaching loss determines device.
Background technology
In today's society, problem of environmental pollution has become one of social concern that we pay close attention to the most.Particularly with
The beginning of the industrial revolution, the sewage such as sanitary sewage and industrial wastewater that human activity is produced enters water body, and quantity has exceeded people
Body self-purification capacity, so as to cause water pollution.Because water is the basis of human survival, so, for pollution control of water, sheet
Utility model provides a kind of measure device for being used to detect nitrogen Leaching loss in soil.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art to determine device, knot there is provided a kind of Soil Nitrogen leaching loss
Structure is simple, easy to use, total nitrogen, ammonia nitrogen, nitrate nitrogen content for determining soil phreatic water.
The purpose of this utility model is achieved through the following technical solutions：
A kind of Soil Nitrogen leaching loss determines device, including body and lid, and the mouth of pipe of the body is threadedly coupled with lid, is managed
The sealed bottom of body, and one layer of filter layer, body side wall corresponding with filter layer are uniformly provided with the bottom outer wall of body
On be also uniformly provided with multiple filter openings.
Further, the body is pvc pipe body.
Further, the caliber of the body is 10-15cm, a height of 100-200cm.
Further, the height of the filter layer is 20cm.
Further, the filter layer is burlap, and the burlap wrapping is in its bottom.
Further, the mouth of pipe of the body is provided with external screw thread, and lid is provided with the internal thread matched with external screw thread.
Further, one layer of corrosion-inhibiting coating is also uniformly coated on the outer wall of the body.
Further, the aperture of the filter opening is 2-4mm.
Application method of the present utility model：Device will be determined to bury to 1-1.5m depths, first dug out during installation more slightly larger than device
Cave, after being put into vertically, be compacted with earthen backfill, at the same note allow tube wall periphery figure be slightly above ground, to prevent ponding from flowing into
Water sample in pipe is impacted；The aperture diafiltration that phreatic water is wrapped up by pvc pipe body bottom burlap enters sampling point in pipe
Analysis；Groundwater sampling monthly 1 time, and avoid rainfall；Gather and height of water level in pvc pipe is measured before water sample, then use manual pumping
Fresh water sample about 300ml is extracted in main internal water accumulation, 24h；Water sample determines total nitrogen, ammonia nitrogen, nitrate nitrogen after 0.45 μm of membrane filtration
Content；Crop Root layer is general within 1m, and therefore the nitrogen of leaching to below 1m, can not can use prison by Root Absorption substantially
The concentration of underground water nitrogen is measured to estimate the Leaching loss of nitrogen.
The beneficial effects of the utility model are：Soil Nitrogen leaching loss assay device structures of the present utility model are simple, user
Just, because Crop Root layer is general within 1m, therefore the nitrogen of leaching to below 1m, can not be utilized by Root Absorption substantially
Device of the present utility model carries out the concentration of the deep underground water nitrogen of 1-1.5m in soil to estimate the Leaching loss of nitrogen, to safeguard that soil is good for
Health environment provides detection means with the preventing and treating of underground water nitrate pollution.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is operating diagram of the present utility model；
In figure, 1- bodys, 2- lids, 3- filter layers, 4- filter openings.
Embodiment
The technical solution of the utility model, but protection domain of the present utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to as described below.
As depicted in figs. 1 and 2, a kind of Soil Nitrogen leaching loss determines device, including body 1 and lid 2, the pipe of the body 1
Mouth is threadedly coupled with lid 2, and one layer of filter layer 3 is uniformly provided with the sealed bottom of body 1, and the bottom outer wall of body 1, described
Multiple filter openings 4 are also uniformly provided with the side wall corresponding with filter layer 3 of body 1.
Further, the body 1 is pvc pipe body.
Further, the caliber of the body 1 is 10-15cm, a height of 100-200cm.
Further, the height of the filter layer 3 is 20cm.
Further, the filter layer 3 is burlap, and the burlap wrapping is in the bottom of body 1.
Further, the mouth of pipe of the body 1 is provided with external screw thread, and lid 2 is provided with the internal thread matched with external screw thread.
Further, one layer of corrosion-inhibiting coating is also uniformly coated on the outer wall of the body 1.
Further, the aperture of the filter opening 4 is 2-4mm.
Buried in use, device will be determined to 1-1.5m depths, the cave more slightly larger than device is first dug out during installation, is put into vertically
Afterwards, it is compacted with earthen backfill, while noting allowing the mouth of pipe slightly above ground, to prevent ponding is flowed into from impacting water sample in pipe；It is shallow
