Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste water treatment technology, and more particularly, to a ceramic separation membrane and a method for producing the same.
In the past, the ecosystem was well maintained because human waste water and wastewater were purified by the midnight effect of nature. However, since environmental pollution is becoming serious due to population increase and industry development, researches on artificial treatment of waste water and wastewater are being actively carried out.
Among such wastewater treatment techniques, membrane separation technology capable of not only treating wastewater but also recovering and recycling effective substances contained in wastewater has been extensively studied. Membrane separation technology has many advantages in that it not only treats wastewater but also recycles and recycles the water in the wastewater with high yield, greatly reducing the load of the wastewater source.
In addition, the amount of chemicals entering the wastewater treatment is low, which can reduce the sludge that is generated, and the physical treatment of the wastewater is less likely to affect the water quality of wastewater. Since the entire system can be operated automatically, there is an advantage that the labor cost and the operating cost can be greatly reduced.
On the other hand, polymer membranes made of polymer materials such as PS, PES, PVDF have been mainly used as separation membranes for filtering out foreign substances. These membranes are widely used in general purification processes, seawater desalination processes, ultrapure water production processes, and sewage treatment processes.
However, in the treatment of livestock wastewater containing high concentrations of pollutants, which are several hundred to tens of thousands times more than those of domestic wastewater, existing membranes made of a polymer material due to the wide pH range, high temperature, high concentration and high viscosity characteristics of the samples, Chemical and heat resistance is weak, so that the replacement cycle is short. Therefore, development of a separation membrane suitable for extreme conditions is required.
The present invention is to provide a separation membrane for a wastewater treatment apparatus excellent in abrasion resistance, chemical resistance and heat resistance.
The flat tubular ceramic separator according to one aspect of the present invention includes a body formed of ceramics and a plurality of through holes horizontally penetrating the body.
According to another aspect of the present invention, the flat tubular ceramic separator may be formed by combining a plurality of pieces provided with a protrusion at one end and a groove corresponding to the protrusion at the other end.
According to another aspect of the present invention, there is provided a method of manufacturing a flat tubular ceramic separator including a main body formed of a ceramic and a plurality of through holes horizontally penetrating the main body, the method comprising the steps of: The method may include extruding and creating a plurality of pieces provided with additional parts and combining the plurality of pieces.
INDUSTRIAL APPLICABILITY According to the present invention, the abrasion resistance, chemical resistance, and heat resistance of the separation membrane become excellent, and the waste water and wastewater can be efficiently treated.
In addition, the pieces can be joined together to form a large ceramic membrane having a width of at least 0.5 m.

A method for manufacturing the above-described flat tubular ceramic separator will be described.
First, a plurality of pieces provided with protrusions at one end and provided with grooves corresponding to the protrusions at the other end are extruded by an extrusion molding method, followed by drying and firing. Each piece consists of a through hole that horizontally penetrates the main body and the main body. Next, a plurality of pieces are combined. Since the pieces are formed by extrusion and then the pieces are combined with each other to form a flat tubular ceramic separator, a large ceramic separator having a width of 0.5 m or more can be produced.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be possible. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
