用于增加通过污水处理系统的均匀出水流动的器械和方法
摘要：
本发明涉及用于增加通过污水处理系统的均匀出水流动的器械和方法。一种在污水处理系统中用于从污水中筛分固体的筛式沉降器包括排出歧管和安装到排出歧管的多个筒形套筒，筒形套筒中的每一个均具有限定腔的外部筛网。套筒中的每一个均包括安置在腔内与排出歧管连通的排出立管。每个排出立管均包括沿着其长度和部分圆周布置在至少一排中的多个模式化开口，每一排均安置成与邻近排的模式化开口成120°旋转角度。每个排出立管均安置成与其邻近的排出立管成30°旋转角度，使得在所述排出立管中的任一个中的任一排模式化开口都不直接面对在任一其他排出立管中的任一其他排的模式化开口。
摘要（英）：

A screen decanter for screening solids from waste water in a waste water treatment system comprising a drain manifold and a plurality of cylindrical cartridges mounted to the drain manifold, each of the cylindrical cartridges having an outer screen defining a cavity. Each of the cartridges includes a drain standpipe disposed within the cavity in communication with the drain manifold. Each drain standpipe includes a plurality of patterned openings arranged in at least one row along the length and partial circumference thereof and preferably comprises three rows of patterned openings, each row being disposed at a 120 degree rotational angle from the adjacent row of patterned openings. Each drain standpipe is disposed at a 30 degree rotational angle from its neighbor drain standpipe such that no row of patterned openings in any of said drain standpipes faces directly at any other row of patterned openings in any other drain standpipe.
