以人工配制的含藻原水为处理对象,比较了UF工艺、生物粉末活性炭+UF组合工艺的除藻效能。结果表明,在膜生物反应器启动阶段,生物粉末活性炭+UF组合工艺对藻类、叶绿素a、藻毒素的去除效果高于UF工艺;生物粉末活性炭形成后,组合工艺对MC-RR、MC-LR的平均去除率达到96.0%和85.2%,能去除全部的藻类和叶绿素a,是较为理想的除藻工艺。
The effects of algae removal by UF membrane process,combined process of biological activated carbon powder and UF were compared with artificial prepared raw water,which some algae contained.The results showed that combined process of biological activated carbon powder and UF was better than UF membrane process for removal of algae cells,chlorophyll a,MC in start-up stage of the membrane bioreactor.The average removal rate of MC-RR and MC-LR reached 96.0% and 85.2% respectively,when the biological activated carbon powder was formed.It was able to remove all algae cells and chlorophyll a.Therefore,it was one of the appropriate processes for removal of algae.
