摘要

  • 摘要: 当前国内很多地方都将曝气生物滤池用于污水深度处理和回用。从保障再生水安全的角度出发，采用小试装置，对曝气生物滤池去除典型环境激素——邻苯二甲酸二（2-乙基己基）酯的效能进行了研究。结果发现，采用厚度1 000 mm的石英砂做滤料，在滤速0.5 m/h的条件下，进水邻苯二甲酸二（2-乙基己基）酯在5～35 μg/L范围内时，即使浓度波动很大，曝气生物滤池出水邻苯二甲酸二（2-乙基己基）酯可稳定在5 μg/L左右，表现出良好的适应能力。滤速升高时，曝气生物滤池去除的邻苯二甲酸二（2-乙基己基）酯能力稍有下降。实验证明了曝气生物滤池在去除邻苯二甲酸二（2-乙基己基）酯方面的良好性能。
    Abstract: Biological aerated filter is widely used in China as an advanced wastewater treatment technology. To evaluate the safety of its effluent, a pilot scale biological aerated filter with 1 000 mm hight quartz sands as filter bed was built in our lab to polish the secondary effluent of a sequencing batch reactor which was fed with domestic wastewater. The concentrations of di (2-ethylhexyl) phthalate (DEHP)in the influent and effluent of the biological aerated filter were carefully determined under different operational conditions. All results showed that, at the filtration rate of 0.5 m/h and the influent concentration of DEHP varied between 5～35 μg/L drasticly, the effluent concentration of DEHP was stable at 5 μg/L. With proper design and operation, biological aerated filter is a feasible technology for DEHP removal.
