含油污水生化处理技术的研究进展

Progress of biochemical treatment technology for oily wastewater

含油污水的生化处理技术可分为2类,即自然生态系统净化法与新型反应器法。自然生态系统净化法主要包括人工湿地法和氧化塘法,新型反应器法主要包括CASS工艺、ABR工艺以及MBR工艺等。介绍了国内外含油污水处理技术的最新研究现状和进展,对各种方法进行评价和比较,并对含油污水处理技术今后的发展提出了建议。

The biochemical treatment technologies for oily wastewater can be divided into two categories, the natural ecosystems purification method and the new type of reactor method. The natural ecosystems purification method mainly includes constructed wetlands method and oxidation ponds method. The new type of reactor includes cyclic activated sludge system （ CASS ） , anaerobic bafflted reactor （ ABR ） , membrane sequencing batch reactor （ MBR ） , etc. The comparison of various methods is performed. The suggestions for the development of the oily wastewater treatment technology in the future are put forward in the end.
