The upper edge of 310 part of babinet of aerobic settling zone 322 is limited less than the upper edge of partition board 320 and with partition board 320.In other words,
The upper edge of the part for limiting aerobic degassing district 321 of babinet 310, less than the portion for limiting aerobic settling zone 322 of babinet 310
Divide upper edge, and less than the upper edge of partition board 320.The upper edge of downflow weir 330 can limit aerobic degassing district 321 with babinet 310
Part upper edge is concordant or the upper edge of the part higher than babinet 310 for limiting aerobic degassing district 321, and downflow weir 330
Upper edge less than babinet 310 the part upper edge for limiting aerobic settling zone 322 and partition board 320 upper edge.It is it is possible thereby to anti-
Only the water in aerobic degassing district 321 is from top overflow most intimate friend's oxygen precipitation area 322, ensures water in aerobic degassing district 321 from aerobic
321 bottom of degassing district flow to aerobic settling zone 322, and then is sufficiently separated nitrobacteria sludge, and in aerobic settling zone 322
Water by overflow to downflow weir 330, avoiding in the water in downflow weir 330 entrainment nitrobacteria sludge.
Optionally, as depicted in figs. 1 and 2, the cross section of babinet 310 be rectangle, the first longitudinal side wall of the lower part of babinet 310
313 lower end obliquely extends downward beyond the lower end of the second longitudinal side wall 314 of the lower part of babinet 310, and the first longitudinal side wall 313
Lower end and the lower end of the second longitudinal side wall 314 it is be overlapped in the up-down direction.
For example, in four longitudinal side walls of babinet 310, length longer two is respectively first vertical in the horizontal direction
The lower end of 313 and second longitudinal side wall 314 of side wall, the lower end of the first longitudinal side wall 313 and the second longitudinal side wall 314 is relative to the first longitudinal side
The upper end of wall 313 and the upper end of the second longitudinal side wall 314 are mutually adjacent, and the lower end of the first longitudinal side wall 313 is located at the second longitudinal side wall 314
Lower end lower section, and the lower end of the first longitudinal side wall 313 and the lower end of the second longitudinal side wall 314 in the horizontal plane projection overlapping,
Gap between the lower end of first longitudinal side wall 313 and the lower end of the second longitudinal side wall 314 forms sludge outlet 312, thus on the one hand
It can smoothly be returned by sludge outlet 312 after can ensureing the nitrobacteria sludge settling in aerobic three phase separation room 311
Oxygen area 130, and on the other hand the structure of the sludge outlet 312 can stop nitrobacteria sludge in aerobic zone 130 from sludge
Outlet 312 enters aerobic three phase separation room 311, ensures nitrobacteria sludge separating effect and the water outlet of degassing settling vessel 300
