| 摘 要： | 生物膜工艺可以有效去除微污染饮用水源中痕量有机污染物，第二级利用是稳态生物膜降解痕量有机物的主要机理。自然有机物可以作为初级基质支持稳态生物膜的生长，而痕量的合成有机物能作为第二级基质被生物膜降解，缓慢衰减的非稳态生物膜在一段时期内仍能保持对痕量有机物的高效降解。

| Abstract: | The biofilm technology can remove trace-level organic compound in micro-pollut ed drinking water sources effectively. Secondary utilization is the main mechanism of which biofilm biodegrade trace-level organic compound. If the natu ral organic matter can supply energy and carbon for the biofilm long-ter m growth and maintenance, trace-level organic compound can be biodegradable as a secondary substrate by biofilm.In nonsteady-state opration,the biofilm decays slowly and sustains high biodegradability of the trace-level substrate for so me time. |
