Abstract: The present invention relates to a pressure hollow fiber membrane module including a housing where a raw water inflow port, a concentrate water discharge port, and a treated water discharge port are formed; an internal flow path that is formed in a central portion of the housing; a plurality of hollow fiber membranes that are arranged about the internal flow path; a treated water collection unit that communicates with the internal flow path and the hollow fiber membranes; a first opening/closing unit that opens/closes an open end of the internal flow path; and a second opening/closing unit that opens/closes an open end of the hollow fiber membrane, and a backwash method for a pressure hollow fiber membrane module including a first backwash step including a step in which an open end of an internal flow path of the module is closed by a first opening/closing unit, a step in which backwash water is injected into a housing through a treated water discharge port, a step in which the injected backwash water flows into a hollow fiber membrane open end via a first treated water collection unit and is filtered through a hollow fiber membrane pore, and a step in which the filtered backwash water is discharged outward through a concentrate water discharge port; and a second backwash step including a step in which the open end of a hollow fiber membrane is closed by a second opening/closing unit, a step in which the backwash water is injected into the housing by the treated water discharge port, a step in which the injected backwash water flows into the internal flow path open end, flows through the internal flow path and a second treated water collection unit, flows back into the hollow fiber membrane open end at the end opposite to the open end at one closed end of the hollow fiber membrane, and is filtered through the hollow fiber membrane pore, and a step in which the filtered backwash water is discharged outward through the concentrate water discharge port. The backwash can be performed uniformly in a longitudinal direction of the hollow fiber membrane module.
Abstract translation: 压力中空纤维膜组件技术领域本发明涉及一种压力中空纤维膜组件，其包括：原料水流入口，浓缩水排出口和处理后的排水口的壳体; 内部流路，其形成在所述壳体的中心部分中; 围绕内部流路设置的多个中空纤维膜; 与内部流路连通的处理水收集单元和中空纤维膜; 第一打开/关闭单元，其打开/关闭内部流路的开口端; 以及打开/关闭中空纤维膜的开口端的第二打开/关闭单元，以及包括第一反洗步骤的压力中空纤维膜组件的反洗方法，所述第一反洗步骤包括以下步骤：将所述中空纤维膜的内部流路的开口端 模块由第一打开/关闭单元关闭，反冲洗水通过经处理的排水口注入壳体的步骤，其中注入的反冲洗水经由第一处理过的水分流入中空纤维膜开口端 水收集单元，并通过中空纤维膜孔过滤，并且过滤的反洗水通过浓缩水排出口向外排出的步骤; 以及第二反洗步骤，包括中空纤维膜的开口端由第二打开/关闭单元封闭的步骤，其中反洗水经处理的排水口注入到壳体中的步骤， 注入的反冲洗水流入内部流路开口端，流过内部流路，第二处理水收集单元在与开放端相反的一端的中空纤维膜开口端流回到 中空纤维膜，并且通过中空纤维膜孔过滤，并且将经过滤的反洗水通过浓缩水排出口向外排出的步骤。 反冲洗可以在中空纤维膜组件的纵向上均匀地进行。
