饮用水水质生物稳定性研究进展

该文分析讨论了饮用水水质生物稳定性评价指标，包括AOC、BDOC、MAP、BGP和AOC—TDWMS等。论述了不同水处理工艺对生物稳定性的影响，得出常规处理对AOC和BDOC具有有限的去除能力；预处理工艺、强化常规处理工艺及深度处理工艺可有效地提高饮用水水质生物稳定性。同时，描述了管网中饮用水水质生物稳定性的特性变化，得出管网水中水质生物稳定性呈现规律性的变化；AOC和BDOC浓度沿管网延伸逐渐降低，或先升高后降低，这主要由水中余氯含量和微生物活性的占优势的一方决定。

Advances in Research of Biological Stability for Drinking Water Quality

The evaluating parameters of biological stability quality were discussed and analyzed in this article, including AOC, BDOC, MAP, BGP and AOC - TDWMS. The influence of different water treatment process on biological stability was discussed. It was shown that conventional drinking water treatment processes can not remove AOC and BDOC efficiently; but pretreatment, enhanced conventional treatment process and advanced drinking water treatment processes can effectively improve biological stability for drinking water quality. Meanwhile, the variability in water distribution were summarized in this article. It was shown that AOC and BDOC concentration decreased usually, or increased at first and then decreased along pipe running, mainly decided by the advantage of residual chlorine and microorganisms.
