Composite oxide-coated electroconductive separation membrane for water treatment and manufacturing method therefor

Abstract

Disclosed is an electroconductive separation membrane for water treatment, the membrane comprising: a metal filter support in a fibrous form; a metal oxide coat layer deposited on the support; and a composite metal oxide catalytic layer applied onto the nanoparticles. Provided is a water treatment system in which the degradation of non-biodegradable organics by electrochemical reactions and the separation of particulate substance through a separation membrane can be simultaneously conducted by water treatment with the electrocatalytic separation membrane according to the present invention. Inaddition, such a water treatment system can exhibit an excellent treatment yield when applied to the advanced treatment of industrial wastewater and can prevent membrane fouling during batch-type andcontinuous type operation by controlling the sheet-type electroconductive separation membrane.

Description

technical field [0001] The present invention relates to a conductive separation membrane for water treatment coated with a composite oxide and a manufacturing method thereof. More specifically, it relates to adjusting the pore size of a filter by impregnating metal oxide nanoparticles on a fibrous metal filter support, and A composite oxide-coated conductive separation membrane for water treatment capable of simultaneously performing electrochemical reactivity and filtration by sintering a coated composite metal oxide catalyst and a manufacturing method thereof. Background technique [0002] Trace amounts of harmful substances in industrial wastewater or sewage treatment water that cannot be removed by existing biological methods may cause widespread and serious problems as new sources of pollution in water systems and drinking water sources. In fact, regardless of domestic and foreign countries, whether in developed or developing countries, the pollution of drinking water s...

AI Technical Summary

Problems solved by technology

However, traditional water treatment processes cannot effectively remove these trace pollutants, and the ozone oxidation process equipped as a high-purity water facility is still limited in treating 1,4-dioxane to an appropriate level

Also, the increase in water demand is shortening the cycle of used water by reprocessing the water after it is drained

Ultimately, although these factors are progressive, they invariably lead to an increase in the water from various sources of pollution and a consequent shortage of available water resources

[0005]In fact, frequent water pollution accidents caused by trace amounts of harmful substances have caused social problems and harmfulness to the human body and ecosystem, resulting in There is a problem of relying on commissioned treatment / disposal of wastewater and requiring high costs

[0006]However, even the separation membrane bioreactor technology, which has been paid attention to as the latest process for advanced sewage treatment, is still limited in removing trace harmful substances, so it needs to be grafted The highly oxidative method removes residual trace harmful substances, thereby solving this problem
