摘　　要：采用预处理-微滤（MF）-反渗透（R0）双膜技术深度处理印染废水。通过改变废水的温度、pH值、回用率和RO的操作压力，探讨其对COD去除率、脱盐效果的影响及原因。试验表明：最佳运行工况是操作压力为1．8MPa、水温为35℃、pH值为6．0～10．0、回收率为80％；此条件下，双膜法对CODcr的去除率和脱盐率分别达到97．4％和97．2％，浊度去除率接近100％，出水水质满足印染工艺回用要求。MF-RO was used for the advanced treatment of the printing and dyeing wastewater after pre- treatment. Through changing the temperature, pH value, recycle rate and operating pressure of reverse osmosis, how and why those related factors affected the removal rate of CODc~ and desalination effect were discussed and analyzed. The results of the test showed that, the optimal operating condition was： the pressure was 1.8 Mpa, the water temperature was 35 ℃, the pH value was 6.0 - 10.0, and the recovery rate was 80%. Under the above condition, the removal rates of CODcr and salinity reached 97.4% and 97.2% respectively, the removal rate of turbidity was close to 100%, the effluent water quality could meet the requirement for the process of printing and dyeing.
