| 摘 要： | 通过对微滤-反渗透污水深度处理系统垢样进行成分分析,确定该系统所结垢为碳酸盐类污垢,采用了加酸方法解决结垢问题。运行结果表明:加酸后,pH降至7.8,朗格利尔(LSI)饱和指数与调节前相比显著降低,系统结垢倾向得到了有效抑制,延长了污水深度处理系统的运行周期。

| Abstract: | The operation status of the advanced wastewater treatment system in PetroChina Dushanzi Ethylene Co.is introduced.According to the component analysis of the scaling in the MF-RO system,it is found that the main ingredient of the scaling is calcium carbonate.The problem can be solved by adding acid into the wastewater treatment system.The operation results show that the pH has been decreased to 7.8,and Langelier saturation index(LSI) has been declined significantly,compared with the original value before pH adjustment.The scaling tendency of the system is efficiently inhibited,and the operation cycles of the wastewater treatment system are extended. |
