摘要
了解单元工艺对不同性质有机物的去除能力对净水工艺的选择具有重要意义。采用膜过滤方法对不同分子量的有机物在净水工艺中的变化情况进行了测定。研究结果表明,传统的混凝沉淀工艺对分子量大于3000的有机物具有较好的去除效果;生物处理对有机物的最有效作用区间是分子量小于500的有机物;而活性炭对分子量在500~3000的有机物吸附能力较强。这一研究结果为净水工艺选择提供了重要依据。
It is helpful on the determination of water purification process to understand the capability of various unit purification processes on organics. The fate of different MW organics through water purification process was detected by membrane filtration in this study. It is found that,coagulation-sedimentation process can remove organics with MW>3000 effectively; the most effective removal range of biotreatment is MW<500; while activated carbon can adsorb obviously organics with MW between 500 and 3000. This will contribute to the selection of purification processes according to the water quality of source water.
