Description

可拆式反应器模块及其连接装置 技术领域
本发明关于一种反应器模块及其连接装置, 尤指一种可拆式的反应器模 块及其连接装置。 背景技术
经过近三十年的发展, 膜生物反应器 (Membrane Bio-Reactor, MBR)已 成为都市污水、 工业废水处理和回用方面极具吸引力和竞争力的选择, 并被 视为最佳可行技术。 因应全球水资源缺乏以及预期用水成本增加, 致使废水 回收议题受到产业界的重视。 而膜生物反应器利用置于活性污泥槽中的薄膜 做为固液分離的操作, 可免除传统废水生物处理系统中的沉淀池及浓缩池等 设置, 以缩小废水处理设施的占地面积及获得更佳的处理水质。 膜生物反应 器技术适用于处理食品与饮料制造废水、 化妆品制造水、 纺织业废水、 纸业 废水、 化学品制造业、 制药业、 皮革业、 洗衣业、 掩埋场渗出液等。 又因薄 膜制造技术的改良等因素, 使其设置及操作成本降低, 增加膜生物反应器的 市场竞争力。
膜生物反应器依类型又可分为中空丝膜式(Hollow Fiber Membrane) , 片 状滤膜式(Flat-Sheet Membrane)、 中空膜管式(Hollow Tube Membrane)以及 卷片型滤膜(Spiral-Wound Element)等。 由于中空丝膜的使用年限不长, 因 此业界开发出中空膜管取代中空丝膜以增加其强度与寿命。 中空膜管以透水 性极佳的聚酯材料管支撑, 外部再以 PVDF或 PES薄膜以特殊方式黏合, 目前 已广为废水处理业者所采用。 图 1 为惯用的中空膜管式膜生物反应器模块示 意图, 参考图 1, 组装膜管 50时, 膜管 50两端胶黏于通水基座 40, 使每根 膜管 50整齐排列于通水基座 40上, 通水基座 40则与集水管 30相连通, 形 成一完整的膜生物反应器模块 7。 进行废水处理时, 将该膜生物反应器模块 7 浸泡入废水池中, 待处理废水透过膜管 50过滤后, 处理过的水进入膜管 50 的空腔中, 经过通水基座 40进入集水管 30排出。
由于膜管 50与通水基座 40间是以胶黏方式固定接合, 因此往往随着使 用时间拉长而发生脱落, 加以若处理的废水具有酸、 碱、 腐蚀、 氧化等性质 时, 胶黏处则更容易受到破坏, 导致未经过膜管 50过滤的废水从胶黏处的孔 隙进入集水管 30, 严重影响膜生物反应器的整体过滤效能。 此外, 为达到加 速过滤的目的, 需要从集水管 30端施以一抽吸的力量使废水进入膜管 50内, 因此当胶黏处一旦产生细微的破损, 将因为此一抽吸的力量而加速破损处的 扩大, 虽然膜管 50本身的过滤功能仍在, 但却因废水由破损处渗入而导致经 过滤后的水仍然含有大量化学物质。
现有技术除了前述提及的胶黏处渗漏问题外, 当从业人员欲进行维修保 养时, 必须先行确认渗漏的所在位置, 才能对破损的胶黏处进行修补, 因此 势必需要将整个膜生物反应器模块 7从废水池中取出, 并逐一检査每根膜管 50与通水基座 40的胶黏处,耗时又费力。且若当渗漏情形严重难以修补或膜 管耗损时, 只能将整个膜生物反应器模块 7汰换, 亦不符合经济效益。
此外, 现有技术所提供的膜生物反应器模块 7多针对特定长度的膜管 50 设计, 且膜管 50两端胶黏于通水基座 40上, 因此无法依据现场需要而及时 调整膜管 50的长度。
综上所述, 膜生物反应器业界极需要一种能够解决上述胶黏处渗漏问题 及能够更方便、 有效率地维修、 更换零组件的技术方案。 发明内容
