摘　　要：本文采用湍流促进器和反冲对陶瓷膜处理钛白粉水洗液的微滤过程进行了强化研究。实验结果表明：采用以上两种方法均不同程度地提高了渗透通量，降低了能耗。考察了湍流促进器结构参数和反冲持续时间、压力、周期对强化效果的影响，确定了合适的湍流促进器结构参数和反冲条件，并对反冲的重复性进行了实验考察。Turbulence promoters and bacanushing were used to enhance filtration process inndcrofiltration of wastewater containing fine TiO2 particles using ceramic membranes. The resultsshowed that the flux was imcreased and energy consumption was reduced by the two methods. Theinfluences of configuration parameter of inserts and backflushing duration, pressure and interval wereevaluated and the appropriate inserts' configurations and backflushing conditions were obtained.
