摘　　要：厌氧条件下对污水处理过程中的吐纳麝香(AHTN)和佳乐麝香(HHCB)进行监测和分析,并设定不同的水力停留时间,分别测定水样中和泥样中两种麝香的质量浓度特征,同时分析不同条件下两者的去除效率.实验结果表明,4个停留时间下进水的HHCB的质量浓度范围为110.95~122.75ng/L,进水中AHTN的质量浓度范围为48.29~63.47 ng/L,出水中HHCB质量浓度范围为22.53~39.16 ng/L,AHTN的质量浓度范围为13.34~28.43 ng/L.平均去除率分别为71.15%和61.58%.泥相两种麝香的质量比范围分别在51.13~75.62 ng/g和19.96~34.75 ng/g之间.随着水力停留时间的增加,厌氧条件下水样中两种麝香的去除率在逐渐降低,但是AHTN降低的幅度大,说明厌氧条件下HRT的增大对AHTN的去除作用在降低.Under the anaerobic conditions of sewage treatment,the AHTN and HHCB were monitored and analyzed.The concentration characteristics of samples were analyzed in water and mud with different hydraulic retention times.The removal efficiency was calculated under different conditions.Experimental results showed that the influent concentration of HHCB ranged from 110.95 ng/L to 122.75 ng/L and the influent concentration of AHTN ranged from 48.29 ng/L to 63.47 ng/L.The effluent concentration of HHCB ranged from22.53 ng/L to 39.16 ng/L and the effluent concentration of AHTN ranged from 13.34 ng/L to 28.43 ng/L.The average removal rates of HHCB and AHTN were 71.15% and 61.58% respectively.Two musk concentrations in mud phase were 51.13 - 75.62 ng/g and 19.96 ~34.75 ng/g.With the increase of hydraulic retention time,the removal rate of two musks in water gradually reduced,but the magnitude of AHTN reduction was greater which showed the removal effect of AHTN on HRT was decreased under anaerobic conditions.
