Description
Technical field
The device that the present invention relates to a kind of suitable for administering terraced fields pollution of area source, belongs to farmland pollution control technology field.
Background technique
Agricultural non -point pollution has become the main reason for numerous water eutrophications in China, and contribution rate has been more than from city
The point-source pollution of city's sanitary sewage and industry, the maximum that the water pollution that farmland face source is caused will be sustainable development of China are chosen
One of war, the agricultural non -point pollution object generated by agricultural drain is more complicated, changes with the type for applying chemical fertilizer, pesticide,
But generally mainly based on nitrogen, phosphorus, organic matter and pesticide residue.Effectively nitrogen, phosphorus concentration are in control agricultural non -point pollution
The key measure of agricultural non -point pollution receiving water body eutrophic extent is reduced, while being also that agricultural non -point pollution controls research side
The important content in face.
There is vast terrace cropping area in Southwestern China and southern area, terraced fields are due to its unique discontinuity, monolithic
The smaller property of area and height fall make it be very different with Plain farmland, but also existing agricultural non -point pollution at present
Control technology: many agricultural non -point pollution controls such as Artificial Wetland Techniques, Riparian Buffer Zone control technology, ecological channel purification techniques
Technology processed is no longer applicable in, and existing non-point source pollution control technique is difficult the practical terrace cropping area vast in China.
Currently, administering the method and apparatus of common agricultural non -point pollution has very much, still, suitable for administering the face of terraced fields
Source polluting device is then fewer and fewer.The present invention is based under this case, propose a kind of installation it is simple, using it is simple, account for it is low
Area is small, treatment effeciency is high and is suitable for managing the device for controlling terraced fields pollution of area source to solve the vast terraced fields production area face in China
Source pollution problem.
Summary of the invention
Place in order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of suitable for administering terraced fields pollution of area source
Device, accomplish installation it is simple, using it is simple, account for bottom surface product it is small while, to realize that efficient, comprehensive processing terraced fields face source is dirty
The purpose of dye problem.
The present invention is achieved through the following technical solutions: a kind of device suitable for administering terraced fields pollution of area source, special
Sign is: including gutter filter device, top process layer, middle part process layer and bottom treatment layer, the top process layer,
It is respectively equipped with filtration channel, multi-functional processing ball and Porous Base inside middle part process layer and bottom treatment layer, top process layer,

Multi-functional processing ball, grit and active carbon are attached on the filter screen of the filtration channel.
The top process layer, middle part process layer and bottom treatment layer can solve water removal filtration channel junction and connect fractionation
At individual three parts.
The device for being suitable for administering terraced fields pollution of area source being fixed on terraced fields by fixed device, fixed device
Including by 2 orthogonal pedestals and perpendicular to the fixed column of 2 pedestals, fixed column, welding on the base, fixed column it is another
Natural soils are inserted into one end.
The pedestal is above the ground level 0.15-0.25m, the 0.15- so that water outlet of bottom treatment layer is above the ground level
0.25m。
The fixed column is the cylinder that long 1.00-1.20m diameter is 0.04-0.06m, and bottom is set hangs down there are four mutual
Straight small iron prop, the small long 0.05-0.1.m diameter of iron prop are 0.03-0.05m.
When work, after the water in gutter enters the water inlet of top process layer by the filtering of gutter filter device,
Due to the part Intercepting effect of bottom plate porous (multi-functional processing ball is also porous structure) and three water filtration channels, water body can be made
Flow velocity greatly reduces to increase the processing time, but after the completion of the processing of top process layer, water will be by the entrance of water filtration channel
Portion's process layer continues to handle, and is finally discharged into next stage terraced fields after the processing of bottom treatment layer and supplies water.So circulation
Back and forth, thus realize installation it is simple, using simple, occupied area is small, treatment effeciency is high and is suitable for the purposes of terraced fields, together
When, it can also realize the water supply and water-saving result to terraced fields.
The beneficial effects of the present invention are: constructing multi-functional processing ball, solves the problems, such as that previous treatment effect is single, make
The multi-functional effect of small area may be implemented in it；Device overall volume is small, and stability is good, and integrated treatment is high-efficient, is suitble to China
Vast terraced fields production area；Subarea processing, not only high treating effect, but also make maintenance simple, it is easy to operate；Filler is more
Sample, compared with previous processing unit, the more diversification of the adsorbent material of the device, can in adsorbed water body with positive and negative charge
Pollutant, so that treatment effect is more preferable；Occupied area is small, occupancy be mostly gutter and can not long-term cropping wall
Body；Each region is divided into the setting of three parts and water filtration channel, reduces water velocity greatly, when stopping water in a device
Between it is longer, increase processing the time；Device integrated can produce, and do not have to carry out engineering in terraced fields, not only saved soil, and
And make device installation simple, it is easy to remove；Device can reversely supply water to terraced fields and save terraced fields water, device processing
Water is discharged into next stage terraced fields, and water is recycled, and reduces terraced fields water diversion, has saved production cost.
