The present invention relates to a flat membrane module for water treatment and a method for manufacturing the same, and more particularly, by laminating a nonwoven fabric on the left and right sides of a flat support using a double-sided adhesive means, assembling a frame, and including the support and the nonwoven fabric. The present invention relates to a membrane module used in a membrane bioreactor (MBR) and a method of manufacturing the same, which include laminating and adhering a separator on left and right sides of a frame.

At present, due to the rapid industrialization and human civilization, environmental pollution is a serious problem. In particular, various sewage and wastewater contain organic substances containing a large amount of carbon, causing odor due to decay and causing oxygen deficiency in the water during decomposition of suspended solids (SS), threatening the aquatic ecosystem. Membrane separation biological treatment equipment is one of the methods developed to obtain stable discharge water quality by preventing the inflow of suspended or suspended materials and other water pollution sources, such as water pollution, into rivers, rivers and seas.

In general, the membrane module used in the membrane separation biological treatment apparatus includes a support having a plurality of flow paths, a non-woven fabric laminated symmetrically on both sides of the support, a separator laminated again on the outside of the nonwoven fabric, and a frame for fixing the module around them. Consists of The flat membrane module manufactured as described above is composed of a plurality of modules composed of one unit, and the flat membrane module unit is immersed in the aeration tank and configured to be connected to the aeration tank and the suction pump installed outside.

The method using the membrane separation type biological treatment device of the above-described configuration is an advanced water treatment method that improves and supplements the disadvantages of the existing activated sludge method, and its demand is gradually expanding.

In particular, the separation membrane used in the membrane separation biological treatment apparatus should have a pore smaller than the suspended solids, and generally uses a micro filtration membrane having a pore size of 0.2 to 0.5 μm. Polymers in the form are used and exist in various ways depending on the choice of modules, applications and scales and apparatus specifications applied to the reactor.

On the other hand, as a major factor influencing the efficiency of the water treatment process using a membrane separation type biological treatment device, the membrane is affected by the performance of removing contaminants from sewage and wastewater, and the lifetime of the membrane. Will be affected. Therefore, without a smooth connection between the membrane and the module can not be expected to improve the water treatment performance and extend the life of the membrane.

As an example of the above-described flat membrane module for water treatment, Japanese Patent Application Laid-open No. Hei 4-70958 communicates and installs a flat membrane in which two permeable membranes are provided with a permeable spacer on a felt through a pair of permeate collection water pipes.

By removing the fixing piece, a gap is formed between the support and the entire flat surface Disclosed is a flat membrane module for water treatment which provides a damping chamber composed of a space between an inner upper surface of the frame and a flat membrane module so that suction pressure acts uniformly.

However, when the membrane module is used for a long time to treat the wastewater of high concentration, the adhesive material constituting the module and the polymer material of the upper layer of the separator are easily detached, causing the phenomenon of lifting, and furthermore, the pores of the membrane are no longer formed. There is a problem that can not expect the separation effect used.

In particular, the adhesive treatment process between the separator and the module for manufacturing a conventional flat panel module is to place a part of the module on the upper layer of the separator and then apply an adhesive to the interface between the separator and the upper layer to bond the module and the separator. Due to the weak bonding strength between the upper part and the adhesive part, when used for a long time, a gap is generated between the separator and the module, thereby providing a cause of decreasing the stability of the product.
