| 摘要 |
A vertical pressurized immersion membrane filtration system is disclosed in the present invention, which includes at least one pressure vessel/tank and a layer of membrane modules which are sealed in the pressure vessel/tank, every layer of membrane modules is provided with at least two membrane modules, and the membrane modules are in parallel to each other, with clearance left between the membrane modules and the pressure vessel/tank, the upper end and the lower end of every membrane module are provided with end plates, the upper and lower membrane modules are air-tightly connected by a connector, the two end plates thus separate the space in the pressure vessel/tank into two sealed end compartments and a middle compartment, the membrane module includes interior membrane fibers and an outer perforated supporting cylinder which surrounds the exterior of the membrane fibers, the pressure vessel/tank is provided with an end water inlet /outlet, the pressure vessel/tank is provided with a middle water inlet /outlet, the pressure vessel/tanks are in parallel with each other. Both the pressurized and the immersion membrane modules can be adopted in the vertical pressurized immersion membrane filtration system of the present invention. The multiple membrane modules work simultaneously, which effectively increases the filtration capacity and efficiency of the filtration system. The present invention can work in multiple operation modes, which improves the versatility and applicability. |
