| 中文摘要 |
| 为了探讨测试有机污染物生物降解性方法的通用性和可比性,建立了用二氧化碳生成量来测试有机污染物好氧生物降解性的合理方法。生物反应瓶容积2L,受试有机物浓度100mg/L(以溶解性有机碳计),接种污泥浓度500mg/L,反应温度25℃,反应时间14d.通过有机物生物降解性的分析,提出了一个生物降解性的评价标准-生物降解性指数(IB).采用本文建立的方法对23种有机物的生物降解性进行了研究,并按生物降解性指数对这些有机物的生物降解难易程度进行了分类。 |

| In this paper,a rational PCD test for determining biodegradability of organic substance under aerobic conditions was established.The volume of bioreactor is 2 L,the concentration of organic substance is 100 mg/L(as DOC),the amount of the inoculum is 500 mg/L(as MLSS),the temperature is 25℃,the duration of test time is 14 days.Index of biodegradation(IB)was elaborated through analysis of biedegradability of organic substances, 23 organic substances were studied with this PCD test, and their indexes of biodegradation were calculated.A classification of biodegradability of the organic substances according to the indexes of biodegradation was suggested. |
