| 1. | Fourth , the membrane recovering method was found within stationary tubular membrane elements and was compared with rotating flow by using experiment , that is , the unloading pressure recovering method is one of the most efficient method , it may reduce the auxiliary time , such as washing , backflush , reverse filtration , but the tubular membrane is washed or backflush or changed after the cycle period are accumulated numerous times
第四、对旋转流静止管式膜的再生进行了实验比较，并提出了旋转流膜管可以通过卸压再生，以减少膜管每次使用后的冲洗、反吹等辅助时间，采用该种方法再生的膜管其渗透通量完全能满足要求，当循环使用一定次数后再进行或冲洗或反吹或更换新膜管。 |
