  • 摘要: 研究了碟管式反渗透（RCDTRO）系统处理垃圾渗滤液的性能，通过测定处理效果和对膜污染的抵抗力，对RCDTRO的性能进行了评估。研究表明：在不进行预处理和后置处理的情况下，一级RCDTRO系统对COD的去除率为（98.89±0.26）%、氨氮（NH4+-N）的去除率为（96.04±0.21）%、脱盐率为（97.53±0.18）%；良好的出水质量和对膜污染的强抵抗力（更长的清洗周期）进一步说明了RCDTRO系统处理渗滤液的技术可行性和经济适用性。其次，实验得出最佳的操作条件范围：压力为4.2~5.0 MPa，加压泵的频率为35 Hz，回收率为65%~75%。结果表明RCDTRO系统处理渗滤液在技术上和经济上都是可行的，并且能够在相对较低的压力下维持较高的处理效率。
    Abstract: In this paper, the performance of radiation channel disc tube reverse osmosis (RCDTRO) for leachate treatment was evaluated for both organic removal efficiency and membrane fouling resistance. It was found that the removal rate of COD was (98.89±0.26)%, that NH4+-N was (96.04±0.21)%, and that the conductivity was reduced by (97.53±0.18)% by the primary RCDTRO system, without any pre-treatment or post-treatment. Good performance related to permeate quality and membrane fouling resistance (longer intervals between cleaning) further proved the technical feasibility and economic applicability of the RCDTRO system for leachate treatment. A bench-scale experiment was also conducted to determine the optimal operating conditions. These were determined to be pressure pump speed of 35 Hz, recovery rate of 65% to 75%, and operating pressure of 4.2 to 5.0 MPa. The results suggested that the RCDTRO system was technically and economically applicable for the treatment of landfill leachate, and that meanwhile, it could maintain high treatment efficiency at relatively low pressure.
