2）, 45 ° of ellipse perforation of the first left avertence of selection（4-1）, the ellipse perforation of 45 ° of the first right avertence（4-2）It is used alternatingly, and first
Ellipse perforation（4）Perforated with the first ellipse（4）Between level interval be 0.062 times of preliminary sedimentation tank width, vertical spacing is
0.062 times of preliminary sedimentation tank width, the first ellipse perforation（4）Long axis length be 0.046 times of preliminary sedimentation tank width, short axle
Length is 0.023 times of preliminary sedimentation tank width；So as to the first ellipse perforation（4）There is more preferable diffusion to current compared to conventional through-hole
Effect, 45 ° of ellipses of the first left avertence are perforated（4-1）, the ellipse perforation of 45 ° of the first right avertence（4-2）It is arranged in rows, upper and lower phase
Neighbour two ranked first oval perforation（4）Incline direction is different, and the incline direction of same row is identical, and current are ellipse by adjacent first
Circular perforations（4）When, the direction spread is different, through first of slotted eye water distribution tracery wall（2）Each layer first it is oval
Shape is perforated（4）Generation energy exchange, effectively balances the flow velocity of each layer；
Current are by first of slotted eye water distribution tracery wall（2）Afterwards, then second slotted eye water distribution tracery wall is flowed to（3）, due to
Second ellipse perforation（5）Including the 45 ° of ellipse perforation of the second left avertence（5-1）, the ellipse perforation of 45 ° of the second right avertence（5-2）, the
The ellipse perforation of two 45 ° of left avertences（5-1）, the ellipse perforation of 45 ° of the second right avertence（5-2）It is alternately distributed and matches somebody with somebody in second slotted eye
Spray wall（3）On, upper and lower adjacent two ranked second oval perforation（5）Incline direction is different, and the incline direction of same row is identical；
And second ellipse perforation（5）Long axis length be 0.046 times of preliminary sedimentation tank width, minor axis length is preliminary sedimentation tank width
0.023 times；Stream passes through the second adjacent ellipse perforation（5）When, the direction spread is different, through second slotted eye
Water distribution tracery wall（3）The ellipse perforation of each layer second（5）Generation energy exchange, balances the flow velocity of each layer again；Pass through first
Road slotted eye water distribution tracery wall（2）, second slotted eye water distribution tracery wall（3）Smooth out uniform fluid flow, realize
The effect of rectification.
4. a kind of rectification square of the ellipse perforation water distribution tracery wall of water intake pumping station preliminary sedimentation aeration tank according to claim 3
Method, it is characterized in that：The stream aqueduct（1）Buried depth be less than preliminary sedimentation tank buried depth.
