Under the optimum operating conditions, 3# could still keep a high removal rate of the contaminant at the flushing loading with NH3-N and manganese simultaneously, while decreasing the removal of NH3-N to about 60% at the flushing loading with organic matter.

在最佳运行条件下，滤池对氨氮和锰复合污染的抗冲击负荷能力较强，仍保持高效的去除效能，但有机物污染负荷使氨氮的去除效率下降到60%左右。

Using soluble glucose and particulate starch as organic matters in the feeding water, the contaminant removal efficiency was investigated in jar test and the fluidized pellet bed reactor.

分别采用溶解性葡萄糖和颗粒性淀粉作为配水中的有机物，考察了混凝（烧杯试验）及造粒流化床对有机物的去除特性。

This research attempts to provide theory solutions to qualitative estimation and scope the water exchange and contaminant transport between stream and groundwater.
