Embodiment Construction

[0031] In the following description, in order for readers to better understand the present application, the details of the present invention will be further described in detail in conjunction with the accompanying drawings.

[0032] The embodiment of the present invention relates to a composite submerged membrane module, which is applied to MBR membrane bioreactor sewage treatment and fluid filtration and separation. The structure of the composite submerged membrane module is as follows: figure 1 shown, including:

[0033] Flat membrane and non-woven fabric (2), the flat membrane is a polyvinylidene fluoride microfiltration membrane, which has a complete overall asymmetric network cross-sectional structure, and the pore size is 0.1 to 1.0 microns. As a preference, the pore size ranges from 0.2 to Between 0.5 microns, the pure water flux is 800-1200L / m 2. bar.hr, the support layer is non-woven.

[0034] The flat film is fixed on the front and rear sides of the bracket (5) (6...

Abstract

The invention provides a composite type immersed membrane component; compared with the prior art, the composite type immersed membrane component improves the impact resistance of a membrane, saves energy consumption, and greatly improves the efficiency of sewage treatment; when the composite type immersed membrane component treats sewage, the sewage penetrates through a flat-plate membrane and is subjected to further fine filtration by an ultrafiltration membrane, and thus the water quality of finally-produced water of a membrane system reaches or exceeds an water inlet indicator of a reverse osmosis membrane.

Description

technical field [0001] The invention relates to a membrane module used in a membrane bioreactor or submerged ultrafiltration process, which is suitable for environmental protection fields such as domestic sewage, petrochemical wastewater treatment and reuse, and particularly relates to a novel membrane module technology. Background technique [0002] Membrane separation is a screening process, which is related to the pore size of the membrane. The driving force of filtration is the pressure difference on both sides of the membrane. The pores only allow water and small molecular substances to pass through to become the permeate, while the substances in the original solution whose volume is larger than the micropore diameter of the membrane surface are intercepted and become the concentrated solution, so as to achieve the purpose of separating and concentrating the original solution. [0003] Due to its unique structure and performance, separation membranes have emerged in env...
