摘要
针对污水收集与处理系统中恶臭气体的组成与特性,比较分析不同情况下活性炭吸附与生物活性炭的脱臭效果。当干活性碳总处理气量达到1.3m^3/g时,出现穿透。将吸附饱和的活性炭填料塔转为生物滴滤反应器后,仍能较快的实现挂膜生长,达到满意的处理效果。直接运行的生物活性炭滴滤器对H_2S的处理效率在95%以上,并具有较强的恢复能力。H_2S平均出口浓度为0.052mg/m^3。循环液pH值与盐度在一定范围内对系统影响不大。
So far as the composition and characteristics of odorant produced from wastewater collection and treatment system is concerned, deodorization efficiency between activated carbon and biological activated carbon were analyzed and compared. When total amount of treated gas reached 1.3m3/g, the activated carbon system appeared penetration. After being transformed into biofilter, it could still realize satisfactory treating efficiency. Biofilter could finish the acclimation for about 7 days. After that, treating efficiency maintained more than 95%. The average outlet concentration of H2 S was 0.052mg/m2, pH and salinity of the circulate fluid did not affect on the system greatly under certain range.
