Embodiment

Embodiment of the present utility model is described with reference to the accompanying drawings.

Simultaneously with reference to Fig. 4 and Fig. 5, be used for the membrane sepn sedimenting system integration apparatus of water Treatment for Reuse, primary structure comprises membrane separation apparatus 1 and settling bowl 2, and settling bowl 2 one are connected with in membrane separation apparatus 1 below, be provided with module 3 and the aerating system 4 formed by the submerged membrane assembly in the membrane separation apparatus 1.Several membrane modules are formed a film piece 3, and several film pieces 3 are formed a membrane stack, two above film pieces 3 side by side on same level attitude, and arranged side by side in vertical direction two to trilamellar membrane piece 3.The quantity of the quantity of contained membrane module and the interior contained film piece 3 of each membrane stack all can be determined as required in each film piece 3.Every tunic piece 3 bottoms are equipped with aerating system 4.
