摘要
分别以新型尼龙材料和普通生物陶粒为填料,进行了上向流曝气生物滤池(UBAF)深度处理印染废水的试验研究。在挂膜和运行阶段,对比研究了新型尼龙材料和生物陶粒的填料性能,并考察了在相同进水环境和运行条件下两种填料的挂膜和运行情况,以及在不同气水比和水力负荷下对低浓度印染废水的处理效果。结果表明:新型尼龙填料较传统生物陶粒启动快、挂膜时间短;在进入稳定运行后,当气水比为3∶1时,两滤池对COD和浊度的去除效果达到最佳,对COD的平均去除率分别为63.4%5、6.5%,对浊度的平均去除率分别为86%8、9%。
Adopting new nylon material and biological ceramsite as media, an experimental study on advanced treatment of printing and dyeing wastewater was carried out in two upflow biological aerated filters （UBAF）. The performance of the two media was compared in biofilm formation and operation stages, and the biofilm formation and operation of the two media under the same influent environment and operation conditions as well as the treatment efficiency of low-concentration printing and dyeing wastewater at different air-water ratios and different hydraulic loading rates were investigated. The results show that the new nylon media has quicker start-up and shorter biofilm formation time than the traditional biological ceramsite. In the stable operation stage, when the air-water ratio is 3 ： 1 , the removal efficiencies of COD and turbidity in the two filters achieve the highest, the average removal rates of COD are 63.4% and 56.5% , and the removal rates of turbidity are 86% and 89% respectively.
