摘　　要：为进一步提升人工快速渗滤系统(CRI)对填料型厌氧折流板反应器(HABR)出水中COD和SS的去除率,通过设计两组不同填料高度的CRI装置,研究不同CRI对处理HABR出水用于农灌的影响。结果表明:在不同水力负荷下,CRI(高柱)的对COD、SS的平均去除率分别为62.79%、85.31%,出水浓度均满足《农田灌溉水质标准》(GB5084-2021)中生食蔬菜灌溉的要求,填料厚度的增加能够提高CRI抗水力负荷和有机负荷冲击的能力,但两组CRI装置对TN和TP的去除率相差不大,且都比较低,使HABR出水中的氮磷元素得以保留,出水有利于农作物生长,在“双碳”背景下,能够实现“水”、“肥”双重资源化。The aim of this study was to enhance the removal efficiency of COD and SS in the effluent of packed anaerobic baffle reactor(HABR)using an artificial rapid percolation system(CRI).Two sets of CRI devices with different packing heights were designed to investigate the impact of CRI on treating HABR effluent for agricultural irrigation.The findings revealed that under various hydraulic loads,CRI(high column)achieved average removal rates of 62.79%for COD and 85.31%for SS,meeting the requirements for raw vegetable irrigation according to"Water Quality Standard for Farmland Irrigation"(GB 5084-2021).Increasing the thickness of fillers enhanced the resistance of CRI against hydraulic load and organic load impacts.However,both groups showed similar low removal rates for TN and TP,allowing retention of nitrogen and phosphorus elements in HABR effluent beneficial for crop growth.This study demonstrates a potential double resource utilization strategy("water"and"fertilizer")under the context of"double carbon".
