摘　　要：采用水生植物滤床系统深度处理养猪废水,开展了不同收割频率条件下系统对污水净化效果的对比研究。实验结果表明,当水力负荷为5 cm/d时,植物收割频率的增加会降低系统对TN和TP的去除效果,而对COD的去除效果则无明显影响。当不进行植物收割时,系统对养猪废水的净化效果最好,对COD、TN和TP的平均去除率分别为71.26%、34.32%和29.52%。因此,合适的植物收割频率是强化APFB系统处理效果的关键因素。Comparison study of aquatic plant filter bed （APFB） system with three different cutting frequencies for swine wastewater advanced treatment was carried out. The results showed that the removal effect of TN and TP decreased with increasing cutting frequency when hydraulic loading rate （HLR） was 5 em/d, but there was no significant influence on the removal effect of COD. APFB was most effective in treating swine wastewater with no cutting frequency, the average removal efficiencies of APFB were 71.26% for COD, 34.32% forTN,29.52% forTP,respectively. Accordingly, it was implied that suitable cutting frequency was the key factor for pollutants removal when APFB was used to treat swine wastewater.
