Description
Technical field
This utility model is related to a kind of processing system, and in particular, it is related to a kind of sewage disposal system.
Background technology
A traditional stage biological denitrification process（Traditional A2/O techniques [1] and its various change form-various improvement A2/
O techniques）, its denitrification ability is relevant with reflux ratio. and theoretical limit superior denitrification ability is R/ (1+R),（R- reflux ratios, including interior time
Stream and exteenal reflux）.In engineering, the general maximum of R values accomplishes 3 ~ 4, therefore maximum limit denitrification ability 75 ~ 80%.Actually by various
According to the A2/O system datas of domestic and international operation, the restriction of reaction condition, sees that the denitrogenation level of a stage biological denitrification process is very
It is difficult stably to keep more than 65%.This engine request TN clearances are 74.2%, therefore cannot be expired using conventional first order section biological denitrificaion
The requirement up to standard of this project treatment of foot.
