At the beginning of a daily flow cycle, the wastewater level in the equalization zone will be at its lowest point.
每天水循环开始时，均衡水流区的污水水位在最低点。

During the balance of the daily flow cycle, the level in the equalization zone will be pumped down by the bucket pumps until the beginning of another flow cycle when it is again at its lowest level.
每天的水流循环达到平衡时，在斗式泵的作用下均衡区水位下降，直到下一次水循环开始时水位将到最低点。
