sediment-free water

The temporary dumping ground of Daya Bay took up 5 × 10~ 5 m~ 3 dredged sediments between May and June, 2003.The water body delamination was disturbed and suspended sediment level in seawater went up during the dumping operation.

2003年5-6月份期间大亚湾临时海洋倾倒区接纳了约50万m3的疏浚泥。

Sediment quality in waters not only affect the benthic organism, but also has close relation with the water quality due to the frequent pollutant interchanges between the sediment and overlaying water. The polluted sediment often becomes the potential source to pollute waters.

水体沉积泥沙质量不仅对底栖生物具有影响，而且由于泥沙与上覆水体相互间频繁的交换作用，泥沙质量与水体水质也有着密切的关系，污染的泥沙往往会成为水域的潜在污染源。

Suspended sediment flux in the sand area is less than that in the mud area, and suspended sediment in whole water column is transported northeastward.

砂质区的悬浮体通量相对较小，且从表层到底层均向东北方向运移。

Stainless steel tanks do not need to be regularly cleaned, the water sediment on a regular basis just to open the sewage tank bottom valve can be discharged.

不锈钢罐无需经常清洗，只需定期打开罐底的排污阀便可排出水中的沉淀物质。

The sediment settled and the water was clear.

杂质沉淀后,水变清了.

During the operation of storing water and retaining sediment, serious deposition in the reservoir leads to backwater level rising rapidly. Therefore it also brings out new river-trained theory of design sediment load and integrated regulation of water-sediment.

开始蓄水拦沙运用，水库严重淤积回水迅速上延，引发设计输沙量和水沙综合调节治河新理论。

Under the same proportion of water and sediment the average surface release of nitrogen and phosphorus in the sediment under the condition of anaerobic is obvious higher than that under the condition of aerobic;

在相同水土比条件下，厌氧条件下底泥N、P营养的平均面释放明显高于好氧条件；
