  • 摘要: 运用反渗透技术对城市处理厂进出水中的溶解性有机物(DOM)进行浓缩富集,利用DAX-8大孔树脂将DOM分为亲水物质(HyI)、类富里酸(FA)和类腐殖酸(HA)3种组分。研究表明,原污水中有机物各组分经生物处理后的总量去除近90%,各组分所占总TOC的百分含量在生化反应过程中也发生了变化:出水中HA组分有降低的趋势,平均下降9.77%,而FA和HyI两大组分所占总和呈现上升趋势,其中类FA物质升高7.94%,而HyI组分百分比略有下降。与进水相比,出水中HyI、FA和HA组分在Ⅲ(色氨酸)、Ⅳ(酪氨酸)区的荧光峰全部消失,而在Ⅰ(类腐殖酸)、Ⅱ(类富里酸)荧光峰变化不大。SUVA和电位滴定结果表明出水有机物的结构发生变化,各组分的芳香性比进水有机物有所增加。研究结果表明,进水中的有机物在污水处理过程中,小分子物质可以被生物利用并形成新的代谢产物释放到水中,大分子物质却较难被生物利用,但在处理过程中其分子构造在一定程度上被微生物改变,系统的生化驯养可以达到构造改变的效果,从而影响出水各组分分子量变化。
