Sign is that the packing volume of micro- oxygen aeration zone (5), slag filler area (6) and slow release carbon source area (7) is 2:2:2, and each filler
Area is two compartments, totally 6 compartments.
8. a kind of micro- aeration type solid carbon source wet land system with advanced nitrogen function according to claim 1, special
Sign is that the packing volume of micro- oxygen aeration zone (5), slag filler area (6) and slow release carbon source area (7) is 2:1:3, and each filler
Area is two compartments, totally 6 compartments.
9. a kind of micro- aeration type solid carbon source wet land system with advanced nitrogen function according to claim 1, special
Sign is that the micro- oxygen concentration for controlling micro- oxygen aeration zone (5) is 0.2mg/L~2mg/L.
10. a kind of denitrogenation of micro- aeration type solid carbon source wet land system with advanced nitrogen function as described in claim 1
Treatment process, it is characterised in that specific treatment process is as follows：
Using a kind of micro- aeration type solid carbon source wet land system with advanced nitrogen function described in claim 1, waste water from
Cistern (1) enters water distribution area (4) by peristaltic pump (2) by water inlet pipe (3), subsequently into micro- oxygen aeration zone (5), adjusts micro-
Oxygen is aerated item (5-1) and carries out intermittent aerating, and the alternate environment of aerobic/anaerobic, when aeration is kept to control the micro- of micro- oxygen aeration zone (5)
Oxygen concentration is 0.2mg/L~2mg/L, ensures sufficient nitrifying process and anaerobic denitrifying environment；It is carried out in slag filler area (6)
Front end nitrifying process provides substrate to the denitrification process of slow release carbon source area (7), and keeps anoxic transitional environment；It is slow in end
It releases and is gradually released to the available carbon source of heterotrophic denitrifying Bacteria supplement in carbon source area (7) by internal carbon source；Then waste water reaches collection
Pool (10) is discharged by delivery pipe (11).
