| 摘 要： | 探讨了苏州河水体黑臭现象，证实了水体发黑主要与存在吸附了ＴｅＳ的带负电胶体悬浮颗粒有关，且腐殖质是吸附物或络合物的主要组成。水体发臭为含硫，氮等有机物降解时逸出ＮＨ３、Ｈ２Ｓ等所致。

| Abstract: | It was proved that the main substance to make the water blackening was the colloid granules with negative electricity which adsorbed FeS and MnS. The adsorbent was mainly composed of humus. Stink of the water was caused by NH3 and HzS escaping when organic matters were decomposed. The blackening and stink index could be decreased by stirring and washing the contaminated sediment with third class surface water repeatedly. The test of resuspended sediment in the water showed that with raising the rate of stirring quality of the water worsened rapidly. |
