| 摘 要： | 用双驱动动态膜压仪测定江、污混合水中有机物含量。通过测定白龙港污水和长江水混合后的膜压和滞回环面积，用它们与相应的经典法CODCr作图，获得了滞回环面积和CODCr之间良好地线性关系，表明用动态膜压法可快速测定混合水中的有机物含量，不须加任何试剂，不会产生二次污染。同时，对实验结果进行了初步的机理探讨。

| Abstract: | The instrument of double-drive dynamic membrane pressure was used to study the organic content of mixing water, which was constituted by wastewa-ter of Bailonggang and water of Changjiang River estuary. The membrane pressure,area of hysteresis loop and CODcr of mixing water have been determined. The good linear relationship between CODCr and area of hysteresis loop has been achieved, which indicated that the method of membrane pressure could be used to fast determine the organic content in mixing water, without any additional chemical reagent and secondary pollution. The elementary mechanism of the result was also discussed. |
