考察了活性污泥法处理污水厂对1,4-二氧六环的去除效果。我们通过比较1,4-二氧六环流入和流出工厂的污水处理系统的停留时间,估计1,4-二氧六环的去除率。估计去除率(8.5%)较低。通过曝气池的挥发和与脱水滤饼一起转移对1,4-二氧六环的去除贡献可忽略不计。这些研究结果表明,几乎所有的去除可以归因于曝气池中的生物降解。
The removal rate of 1,4-dioxane in a sewage treatment plant with an activated sludge system was examined. We estimated the removal rate of 1,4-dioxane by comparing 1,4-dioxane inflow into and outflow from the plant, in relation to the sewage retention time of the treatment system. The estimated removal rate (8.5%) was low. Volatilization by aeration tanks and transfer with dehydrated cake negligibly contributed to the removal of 1,4-dioxane. These findings indicate that almost all of the removal can be attributed to biodegradation in the aeration tank.
