6. small watershed high-effective cleansing denitrification system according to claim 2, it is characterised in that：Described tide matrix is under
Supreme to be followed successively by cobble rock layers, the first granule rock layers, turf layer and the second granule rock layers, the particle diameter of the first bird's-eye gravel is less than second
The particle diameter of bird's-eye gravel, the interior plantation in the second granule rock layers of tidal flow artificial wetland have emergent aquactic plant.
7. small watershed high-effective cleansing denitrification system according to claim 2, it is characterised in that：Tidal flow artificial wetland goes out
Mouth is provided with industrial flow meter with the pipeline that perforation water distributor connects, and industrial flow meter is located at the second timing constant flow pump and perforation cloth
Between water pipe, the exit of perforated catchment pipe is provided with time control solenoid valve.
8. small watershed high-effective cleansing denitrification system according to claim 2, it is characterised in that：Described electric power system includes
Solar panel, electric power system are motor, the first timing constant flow pump and the power supply of the second timing constant flow pump.
9. a kind of method that decontamination denitrogenation is carried out based on any described small watershed high-effective cleansing denitrification systems of claim 1-8,
Comprise the following steps：
If the 9.1, rotating cage is installed on cross section of river and carries out in-situ immobilization, sewage is directly over rotating cage, if constructing in addition strong
Change pond and carry out showering, then sewage is pumped into and strengthened in pond, hydraulic detention time 3-12h, motor driving rotating cage rotates, people
The indigenous microorganism of work pasture and water and the enrichment of carbon fibre ball carries out aerobic decomposition and nitrification, obtains one-level sewage；
9.2nd, one-level sewage is pumped into tidal flow artificial wetland by very first time constant flow pump, passes through very first time constant flow pump control
The flooding time of tidal flow artificial wetland processed, flooding time 10-30min, the hydraulic detention time of tidal flow artificial wetland are
3-12h, the organic pollution in one-level sewage is attached to biomembrane absorption in tide matrix and oxidation Decomposition, ammonia nitrogen are damp
Nighttide matrix is oxidized to nitrate nitrogen and nitrite nitrogen, the adsorbed retention of phosphorus, while carries out ion exchange and anti-nitration reaction, and one-level is dirty
Mass fraction is that 0.6-17.3% nitrogen and 1.4-41.2% phosphorus are absorbed by emergent aquactic plant in water, obtains B-grade sewage；
9.3rd, B-grade sewage is pumped into continuous filter by the second time constant flow pump, enters the first continuous filter by water distributor of perforating, and two
Level sewage pass sequentially through the first continuous filter, the second continuous filter, the 3rd continuous filter and the 4th continuous filter, persistently carry out it is aerobic decompose,
Nitration reaction and anti-nitration reaction, removal organic polluter, total nitrogen and total phosphorus are removed, obtain three-level sewage.
9.4th, three-level sewage is drained through time control solenoid valve, drain time and the tide person who lives in exile of modularization land percolation system
The filling time of work wetland is identical.
