超滤膜处理传统二级出水试验研究

Experimental study on treatment of traditional secondary effluent by ultrafiltration membrane

用6种不同的超滤膜处理某传统二级出水,在无动力、无清洗条件下连续运行74h,得出6种膜对COD、UV254、浊度的去除效果及连续运行通量衰减的变化规律。膜对COD去除效率在45%~80%,对UV254去除率在20%~80%,对浊度的去除率在95%以上,最高可达99.9%。

A traditional secondary effluent was treated with six different ultrafiltration membranes, and operated continuously for 74 hours under no power and no cleaning conditions. The removal effect of COD, UV254, turbidity and continuous flux decay of the six membranes were obtained. The removal efficiency of COD is between 45% and 80%, the removal rate of UV254 is between 20% and 80%, and the removal efficiency of turbidity is above 95%, up to 99.9%.
