活性污泥法对多环麝香污染物去除效果的研究

Removal of Polycyclic Musks in Activated Sludge Process

以佳乐麝香(HHCB)和吐纳麝香(AHTN)作为新兴有机污染物的代表,研究了传统活性污泥处理工艺对污水中多环麝香的主要去除途径及去除效果。结果表明,在污水处理过程中,超过50%的HHCB和25%的AHTN因吸附在颗粒相上而转移到污泥中,这是在污水处理过程中去除多环麝香的重要途径。污水经曝气沉砂池、初沉池、活性污泥处理系统和二沉池等一系列流程处理后,对HHCB和AHTN的总去除率均可达到85%以上。

The main removal pathway and removal efficiency of polyeyclic musks from wastewater in traditional activated sludge processes were studied using HHCB and AHTN as a representative of emerging pollutants. The results show that more than 50% of HHCB and 25% of AHTN are adsorbed onto particles and transferred into sludge, which is considered as the main removal pathway of polycyclic musks during wastewater treatment. The total removal rates of HHCB and AHTN can reach over 85% after wastewater is treated by aerated grit chamber, primary sedimentation tank, activated sludge treatment system and secondary sedimentation tank.
