摘　　要：针对沈阳某污水处理厂三期进水时常颜色发黑的问题,通过感官分析、常规生化指标检测、色度分析、悬浮物及沉淀物成分分析,对黑色污水与灰色污水进行了分析对比,初步确定污水变黑的原因在于水中的悬浮物含量过高,且污水中应含有铁化合物、硅酸盐及其他物质。后续对沉淀物中的无机物成分进行进一步检测或在污水发黑时段在进水管线沿程进行污染源排查,找寻污染源并进行处理。In response to the problem that the water in the third phase of the southern sewage treatment plant of Shenyang is often black in color,sensory analysis,routine biochemical index detection,chromaticity analysis,suspended solids and sediment composition analysis were done to the black sewage and gray sewage,and it was preliminarily determined that the cause of the blackening of sewage was that the total suspended solids in the water were too high,and the sewage should contain iron compounds,silicates and other substances. In the follow-up,further to test the inorganic components in the sediment,or to check the pollution source along the water inlet pipeline during the blackening period of the sewage,find the pollution source and deal with it.
