Description
Technical field
It is especially a kind of for reducing nitrogen and phosphorus pollutants concentration in paddy field drainage the present invention relates to a kind of reoxygenation collection Tu Chi
Reoxygenation collection Tu Chi.
Background technique
The ratio shared in non-point pollution of China's agricultural non-point source pollution at present is increasing, the nitrogen phosphorus in agriculture water-break
Equal substances are increasingly becoming the most important pollution sources of water eutrophication.To solve the problems, such as agricultural non-point source pollution, the prior art includes
Artificial swamp, Vegetative Filter Strips, meadow buffer strip, bank buffer area, irrigation water ecology, level of ground water control etc..These skills
Art relies primarily on particulate matter and intercepts (physical action) during playing a role, and the nitrification and denitrification effect of microorganism is (raw
Object chemical action) and the modes (biological effect) such as be absorbed and utilized of plant Water phosphor contaminant content is reduced.These skills
Art can not play its advantage because being influenced by factors such as season, ecological factor, local conditions differences in paddy field drainage channel, and
Clean-up effect is limited.For in the removal technology of nitrogen and phosphorus pollutants in paddy field drainage, essential link is the nitre of microorganism
Change effect, and the necessary condition of nitration reaction is that have oxygen participation, so how to improve the content of oxygen in paddy field drainage becomes
A key link of pollutant removal in paddy field drainage.In addition particulate form pollutant accounting is obvious in paddy field drainage, from draining
Source intercepts particulate form pollutant and also becomes the problem to be solved in the present invention.
Summary of the invention
Technical assignment of the invention is to be directed to the above the deficiencies in the prior art, and provide one kind for reducing in paddy field drainage
The reoxygenation collection Tu Chi of nitrogen and phosphorus pollutants concentration.
The technical solution adopted by the present invention to solve the technical problems is: one kind is for reducing nitrogen and phosphorus pollution in paddy field drainage
The reoxygenation collection Tu Chi of object concentration is respectively provided with a side plate in the two sides of the bottom plate, before the bottom plate including bottom plate
End is equipped with foreboard, is equipped with backboard at the rear portion of the bottom plate, the side plate is vertically arranged with bottom plate with foreboard, the side plate
Height is higher than backboard, and the height of the backboard is higher than foreboard, and the height difference of backboard and side plate is 10~20cm, and the backboard is outward
It is obliquely installed, it is vertical with the backboard to be equipped with support plate in the top of the backboard, it is equidistantly equipped in the support plate several
Stream tooth is chosen, is equipped with several disturbance teeth at the top of the foreboard.
Be further improved: the stream tooth of choosing is in strip structure, disturbance tooth structure triangular in shape.
Be further improved: the end of the bottom plate and the bottom of the backboard are hinged by hinge, at the bottom of the foreboard
Portion and the front end of bottom plate are equipped with the fixed plate of tape punching, are inserted with fixing bolt in the fixation hole.
Be further improved: the height difference of the side plate and backboard is 16cm.
Be further improved: the angle between the backboard and bottom plate is 120~140 °.
Be further improved: the angle between the backboard and bottom plate is 135 °.
Advantages of the present invention: reoxygenation integrates Tu Chi and selects plank as raw material, and cost is low, is easily placed about paddy field drainage
At mouthful, the oxygen content in paddy field drainage water body can be increased, the nitration reaction for microorganism in paddy field drainage provides Oxygen Condition,
Water element is discharged for removal rice field to provide safeguard；Reoxygenation collection Tu Chi itself has a constant volume simultaneously, can intercept part
Soil particle at paddy field drainage mouth reduces paddy soil number of dropouts, reduces particulate form pollutant load in paddy field drainage.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is side view of the invention.
Fig. 3 is the structural schematic diagram of support plate of the present invention.
Specific embodiment
The present invention is described below with reference to the accompanying drawings of the specification.
As shown, a kind of reoxygenation collection Tu Chi for reducing nitrogen and phosphorus pollutants concentration in paddy field drainage, the bottom of including
Plate 1 is respectively provided with a side plate 3 in the two sides of the bottom plate 1, foreboard 2 is equipped in the front end of the bottom plate 1, in the bottom plate 1
Rear portion is equipped with backboard 4, and the side plate 3 is vertically arranged with bottom plate 1 with foreboard 2, and the height of the side plate 3 is higher than backboard 4, described
The height of backboard 4 is higher than foreboard 2, and the difference in height between two side plates 3 and backboard 4 forms water inlet, water inlet and paddy field drainage
Mouth is directly connected, and difference in height between two side plates 3 and foreboard 2 forms water outlet, the height difference of backboard 4 and side plate 3 for 10~
20cm, the backboard 4 are obliquely installed outward, vertical with the backboard 4 to be equipped with support plate 5, In in the top of the backboard 4
It is equidistantly equipped with several choose in the support plate 5 and flows tooth 51, is equipped with several disturbance teeth 21 at the top of the foreboard 2.
The stream tooth 51 of choosing is in strip structure, the disturbance tooth 21 structure triangular in shape.
The end of the bottom plate 1 and the bottom of the backboard 4 are hinged by hinge, bottom and bottom plate 1 in the foreboard 2
Front end be equipped with the fixed plate 11 of tape punching, fixing bolt 12 is inserted in the fixation hole.
The height difference of the side plate 3 and backboard 4 is 16cm；Angle between the backboard 4 and bottom plate 1 is 120~140 °；Or
Person is that the angle between the backboard 4 and bottom plate 1 is 135 °.
Its working principle is that: when in use, collection Tu Chi is installed on paddy field drainage mouth, the top collection Tu Chi (side plate when installation
Top plate) with paddy field drainage mouth upper end with high, Ji Tuchi is in a vertical state, top (water inlet of the water in rice field from backboard 4
Mouthful) flow into and collect in native pond, water flow is supported the blocking of plate 5 at this time, water flow from choosing in support plate 5 passed through between stream tooth 51 into
Enter and collect in native pond, when the water level in Ji Tuchi rises to the bottom of flow-disturbing tooth 21, the water collected in native pond at this time passes through flow-disturbing tooth
It is flowed out out of Ji Tuchi in gap between 21.
For water flow during by collecting native pond, water flow is when by choosing stream tooth 51 and flow-disturbing tooth 21, original water body quilt
It is broken, time of contact and the area of water flow and air are increased, to improve the content of oxygen in water body.
In addition, water body when by collecting native pond, can reduce rice field with soil particle entrained in catching portion water distribution component
With nitrogen and phosphorus pollutants content existing for particulate form in draining, paddy soil number of dropouts is reduced.When the silt collected in native pond reaches one
After determining thickness, collection Tu Chi can be removed from the discharge outlet in rice field, then the fixing bolt 12 for collecting native bottom of pond portion is removed again, is made
It obtains bottom plate 1 to downwardly turn over, by the soil reuse on bottom plate 1 to rice field, fixing bolt 12 is inserted into fixed plate 11 again after cleaning out
Perforation in, bottom plate 1 is fixed, will finally collect Tu Chi again and be put into the discharge outlet in rice field, in water body by reoxygenation collection soil
Chi Hou, not only increases the content of oxygen in water body, and also reduces the turbidity of water body, so that the turbidity of water body is from 5000NTU
It is reduced to 1200NTU.
Table 1 is synchronization, and the oxygen content that initial water body and reoxygenation collect soil pool inner water body compares
