摘要:

从温度、盐度、悬浮固体等常规水质指标和表面活性剂、油脂等典型污染物两个方面综述了水质条件对氧传质影响的国内外研究进展。温度、盐度等指标虽然有相应修正公式,但不足以体现实际过程;表面活性剂等污染物对氧传质过程是抑制还是强化与具体物质及浓度等有很大关系。目前研究多为清水实验,后续应强化实际活性污泥系统的研究。

关键词: 氧传质, 温度, 盐度, 表面活性剂, 油脂

Abstract:

The research progress in the effects of water quality conditions on oxygen mass transfer both in China and abroad are summarized in two aspects:routine water quality indexes, such as temperature, salinity, suspended solids, etc. and typical pollutants including surfactants, oil, etc. Although temperature and salinity have modified formula correspondingly, it is still insufficient to reflect the real process. Whether surfactants and other pollutants inhibit or intensify oxygen mass transfer is mostly related to the concrete substance and its concentration. The present research is mostly carried on with clean water tests, but the subsequent research should be on the enhancement of real activated sludge systems.

Key words: oxygen mass transfer, temperature, salinity, surfactant, oil
