摘要

试验对正在运行的生物预处理以及后续处理工艺进行了调查,了解了生物预处理的出水有机物变化以及对后续处理工艺的影响。试验表明:由于微生物新陈代谢产物溶解在水中的缘故,生物预处理出水会出现有机物增加的现象,影响了后续处理工艺的去除效果。对出水进行的分子质量分布测试表明,微生物新陈代谢产物会产生大量的消毒副产物。生物预处理无法降低水的致突变性。

Abstract

The water quality in biological pretreatment and succeeding tr eatment process in running have been investigated to understand the effect of bi ological treatment on organic removal and the influence on the succeeding treatm ent process. It is found that due to the metabolism product dissolves in water, organics in the biological process treated water increases,resulting in decrea se of removal efficiency in the succeeding treatment process. The molecular weig ht distribution of the effluence water is determined and found that microbial me tabolism product could produce a lot of disinfection by-products. The biological process could not mitigate the mutagenicity.
