摘　　要：采用新型抗污染纳滤膜,研制开发了纳滤中试成套设备处理生活污水,确定了其最佳操作压力为600kPa,产水量为12L/min,回收率为85%,除盐率为72.8%。在该条件下,对生活污水的处理效能高,对COD、BOD、TP、Fe的去除率最高分别达到95%、96%、96.27%和100%,平均去除率分别为85.82%、88.51%、89.49%和92.50%。出水除氨氮外,均达到生活杂用水标准。设备运行周期为30d,采用化学清洗与水力冲洗相结合的清洗方法,化学清洗剂为0.1mol/L的NaOH溶液。The pilot-scale integrated nanofiltration equipment with anti-pollutant NF membrane was developed to treat domestic wastewater. The equipment was tested to determine the optimal operation conditions: operating pressure:600kPa, water output: 12 L/min, recovery rate: 85% and demineralization rate: 72.8%. Under these conditions, it possessed high treating efficacy for domestic sewage; the highest removal rate for COD, BOD, TP, FE reached to 95%, 96%, 96.27%, and 100%; average removal rates were 85.82%, 88.51%, 89.49% and 92.50% respectively. Except for ammonia and nitrogen, the effluent water reached the standards of domestic water discharging; the period of the equipment operating was 30 days; the chemical washing in combination with hydraulic flush was adopted for washing the equipment with the chemical washing agent of 0.1 mol/L NaOH solution.
