摘要: 实验室自行研发的PVDF/PMMA/TPU共混体系的五孔支撑膜具有高强度耐冲击的特点, 在一定程度上改善了传统中空纤维膜的断丝情况。将选择典型的、具有代表性的MBR工艺流程, 采用自主研发的五孔膜制成帘式组件, 用于处理经水解酸化后的印染废水。实验讨论了水力停留时间, 曝气强度和污泥浓度对于出水水质的影响, 最后确定最优的操作条件为:MBR的水力停留时间为20 h, 曝气强度为2.45 m³/m²·h, 污泥浓度为4 500 mg/L。

Abstract: The five-bore fiber blends with PVDF/PMMA/TPU, which developed by our laboratory, has the characteristics of high intensity and impact resistance.To some extent, the five-bore fiber was found to improve the situation that traditional hollow fiber membrane is easily broken.Typical and representative MBR process were used in the experiment with the self-made five-bore fiber shade type membrane module to treat the dyeing wastewater after the process of hydrolysis acidification.Effects of hydraulic retention time, aeration intensity and sludge concentration on the effluent water quality were discussed in the article, and finally the optimal operating conditions were determined, which the MBR hydraulic retention time was 20h, aeration intensity was 2.45m³/m²·h, the sludge concentration was 4500mg/L.
