Disclosed is a membrane module unit in which a plurality of membrane modules is coupled together in parallel by coupling means, the membrane module including a sheet-like filter membrane and holding frame members that hold the filter membrane at two opposed sides of a peripheral edge of the filter membrane, wherein the coupling means clamps the holding frame members at the same sides of the filter membranes together by two opposed clamping members. According to the invention, provided is a membrane module unit in which structure is simple, assembly, disassembly, and maintenance can be easily performed, and a plurality of membrane modules can be reliably coupled together. Provided are also an assembly method, disassembly method, and maintenance method of the same, and a water-treatment apparatus.

A hollow fiber membrane module in which a housing body forming the hollow fiber membrane module includes an insertion opening into which end parts of the plurality of hollow fiber membranes are inserted so as to be fixed and held, and an opening portion which exposes open end surfaces of a plurality of hollow fiber membranes inserted from the insertion opening to outside, and a cover that blocks the opening portion of the housing body. According to the present invention, it is possible to provide a housing enabling open end surfaces of hollow fiber membranes to be sealed by easily exposing the open end surfaces of the hollow fiber membranes when the hollow fiber membranes are damaged.
