浑浊度是自来水水质监测常检项目。有关文献对检测浑浊度的水样保存条件只规定为温度4℃。而我们在实际工作中发现凡深井自来水(一般含铁量[以mg/L计]在0.5以上)水样的浑浊度,无论何种温度保存,都随存放时间增长而逐渐升高,表现出明显不稳定性。原因是,深层地下水中的铁
Turbidity is tap water quality monitoring of the project. Relevant documents on the detection of turbidity water storage conditions for the provisions of only 4 ℃. However, in actual work, we found that the turbidity of water samples in deep well tap water (usually containing iron content [in mg / L] above 0.5), no matter what the temperature was stored, increased gradually with increasing storage time and showed Obvious instability. The reason is deep iron in the groundwater
