一种浸没式柱式膜组件
本技术涉及环保产品领域,更具体地说,是涉及一种浸没式柱式膜组件。
技术介绍
在饮用水和再生水领域,采用膜法进行提标改造已成为当前环保产业的技术发展趋势。现有浸没式膜产品主要分为帘式浸没式和柱式浸没式,从使用效果来看,除了MBR领域以外,柱式浸没式膜在市场上占据主导地位,这与其产品在相同条件下填充密度更高,曝气系统效率较高、效果较好有关。现有柱式浸没式膜产品主要采用将中空纤维膜两端集束且浇注固定的方式制备,组件在使用过程中需要进行曝气,曝气方向为组件下端至上端,因此在组件运行过程中上端易产生污染物的蓄积,从而导致中空纤维膜上根部污染较为严重,影响膜组件的使用效率;此外污染物在组件上端蓄积也会对固定的中空纤维膜进行挤压,膜上根部发生形变甚至断丝,影响组件的产水质量。
