Description
Technical field
The utility model belongs to ecological control techniques field, more particularly to a kind of step rice field of Control of Agricultural Non-point Source Pollution
Inlay ecological canal cleaning system.
Background technology
The existing technology for purifying sewage on the spot and device or facility have had much, obvious particular for first flush effect
Sewage, stores initial stage sewage using storage pond, discharges or be sent to sewage disposal at dry season after dosing coagulant precipitation
Factory is processed, and reaches the purpose of control sewage pollution.
But, above-mentioned facility is typically made up of multiple structure divisions and increased floor space, due to many city rivers week
Confining space is limited, is unfavorable for sewage arable land change.Coagulation process needs the medicaments such as coagulant, system to run by electric energy simultaneously
Purification cost is increased, and the more complicated cost of structure is higher, as such device belongs to pure engineering measure, do not had and surrounding
Environment carries out effective integration.
At present, artificial swamp, has as a kind of novel ecological sewage disposal technology compared with traditional sewage water treatment method
There are high treating effect, during-operation service convenient management, engineering capital construction and running expense low, the advantages of aesthetics of environment value is high, therefore quilt
It is widely used in the fields such as process sanitary sewage, industrial and agricultural production waste water.
Matrix is adopted mostly in prior art, and matrix is that plant and microorganism provide somatomedin, provide for sewage seepage flow
While good hydraulics, it is also possible to by precipitation, absorption and the effect directly removal pollutant such as filter.Its species, group
The selection of method of completing the square and height is then the core of constructed wetland waste water treatment technology.Vary as sewage property is present, because
And not a kind of single-matrix being capable of all sewage of effective process.Most-often used is rubble among these, in addition with zeolite,
Soil, cobblestone, cinder, flyash etc..The physical and chemical reaction that be removed by wet land filler matrix, plant of the artificial swamp to phosphorus
What several respects collective effect such as the absorption of root system and the accumulation of microorganism was completed.But the absorption of plant and the accumulation of microorganism
Act on the removal to phosphorus and only account for a little part.The main removal mechanisms at work of phosphorus is the suction-operated of matrix, the positive phosphorus in water body
Hydrochlorate, when current flow through wetland dielectric surface, is adsorbed by medium, and the quality of this adsorption capacity depending on wetland will be
It is no to have good hydraulic conductivity and higher specific surface area.And the general artificial Wetland Substrate such as phosphor-removing effect such as sand, gravel
Poor, the treatment effect such as the shale with high porosity and adsorptivity, vermiculite, calcite, porous media (LECA) is preferable, but because
Relatively costly the problems such as is more difficult to carry out popularization and application.And existing Artificial Wetland Techniques are being administered as obstruct Rural Plane Source Pollution
Thing is entered on the last line of defense of water body using little.
On the one hand Control the Plan Pollution Sources will reduce the nitrogen phosphorus of agricultural production from source and apply the management rural area with ordering
House refuse and livestock and poultry cultivation, on the other hand will start with from pollutant is reduced into dirty possibility, intercept on the spot and cut down rural area face
Pollute in source.As the last line of defense for intercepting Rural Plane Source Pollution thing and entering water body, it should with important environmental functional and
Effect.It is not deep enough with regard to intercepting to Rural Plane Source Pollution at present.
