DTRO在煤化工高含盐有机废水处理中的应用

为解决某煤化工企业高含盐有机废水处理系统存在的"盐不平衡"、"水不平衡"问题,达到高含盐浓水提浓减量的目的,对DTRO装置处理高含盐有机废水进行了技术论证和中试试验,其产水水质、处理能力和运行周期均满足使用要求,并在此基础上对原卷式反渗透膜装置进行工程改造,改造后运行效果良好,解决了原系统存在浓水不平衡问题。

DTRO application in coal chemical industry high salt-containing organic wastewater treatment

In order to solve the problems of "salt imbalance" and "water imbalance" which existing in the high salt-containing organic wastewater treatment system of a coal chemical enterprise, and then, achieve the goal of high salinity brine concentration and quantity reduction, the feasibility of DTRO device treating high saltcontaining organic wastewater was discussed in technical part with a pilot test carried out at the same time, the results showed that, the produced water quality, treatment capacity and operation cycle of the said device all met the use requirements. On the above basis, original spiral reverse osmosis membrane device was modified in the project, and its operation effect after the modification was good, which finally solve the problem of concentrated water imbalance of the original system.
