In general, wastewater, sewage and sewage pollute the environment, so it is made into the first treatment water through the first purification process, and then discharged to the river or the sea. Contains suspended solids. Here, the suspended solids are solid substances composed of particles (organic and inorganic) having a size of 0.1 micron or more, and are also called suspended substances because they suspend water.

Water containing the suspended solids (suspension material) (ie, primary treated water and industrial water) is unsuitable for use as general water in homes or industrial sites. Therefore, a number of filtration apparatuses for water treatment have been developed to save water and water resources and to increase energy savings by treating all treated waters in secondary.

Hereinafter, with reference to the accompanying drawings will be described in more detail the filter device for cartridge type water treatment of the present invention.

Figure 1 is a schematic diagram showing the operating principle of the cartridge type water treatment filtration device according to an embodiment of the present invention. According to FIG. 1, the inflow source water introduced into the main body 10 through the inflow source inflow portion 12 undergoes a filtration process for removing suspended solids from the main body 10 and then through the treated water outlet 14. It is discharged to the outside.

When the suspended solids accumulate inside the main body 10 while the filtration process progresses, or the flow rate of the treated water discharged through the treated water outlet 14 is slowed down, the pressure inside the main body 10 is reduced. Depending on the degree of change, such as flow rate, the filtration process is stopped and the backwashing process for washing the filter medium 26 is performed. The backwashing process is performed by introducing backwashing water and backwashing air. The backwashing water flows into the main body 10 through the backwashing water inlet 16 or the inlet water inlet 12 formed under the main body 10. For example, influent water may be used as a backwash water or a separate backwash water may be added. In addition, the backwashing air is supplied into the main body 10 through the backwashing air inflow plate 30 installed under the main body 10.

In addition, chlorine and biodegradation enzymes can be introduced to effectively desorb microorganisms (biofilm) formed in the contaminants and media captured during the backwashing process, and a chemical tank 40 for storing chlorine and biodegradation enzymes is provided separately. By connecting to the main body 10, the amount of chlorine or biodegradable enzyme can be adjusted using the chemical control valve (42).

2 is a front cross-sectional view of the cartridge-type water treatment apparatus main body in which the filter medium is installed, according to an embodiment of the present invention. According to FIG. 2, after the inflow of inflow water is introduced through the inflow source inflow portion 12 formed in the lower portion of the main body 10, the inflow source water fills the inflow porous pipe 20. The inflow porous pipe 20 is formed in a cylindrical shape to discharge the inflow water evenly in all directions, is installed in the center of the body 10 in the axial direction, the surface has a plurality of holes.

The inlet porous pipe 20 is installed in the axial direction of the main body 10 and takes the structure of discharging the inflowing raw water through the hole, the inflowing raw water is sprayed in the vertical direction with respect to the filter medium (26). Therefore, the contact surface between the inflow source and the media 26 is wider and the contact frequency is increased than the case where the inflow direction of the inflow source and the installation direction of the media 26 are the same, so that the suspended matter can be more effectively removed.

The media 26 is composed of various types of fiber yarns. In the center of the main body 10 around the inlet porous tube 20, a thick mediator 26 is installed, and thinner media 26 are installed at different densities toward the outer periphery, so that the thinn media media inside the outlet porous tube 24 are installed. 26) is installed. Therefore, relatively large coarse particles are captured in the coarse media 26 around the inlet porous pipe 20, and fine particles are captured in the outer thin media 26 to capture suspended matter by using the entire filter layer. Will be.

The fiber yarn forming the filter medium 26 uses a material of acid and alkali resistance to effectively trap various contaminants contained in the influent and at the same time to ensure durability.

In addition, the filter medium 26 is fixed up and down by the upper filter fixing frame 28a and the lower filter fixing frame 28b, respectively, so as not to be separated by the flow of inflow water or backwash water.

The outflow porous tube 24 is formed at the outermost side of the main body 10 to discharge the treated water that has undergone the filtration process to the outside. Outflow porous tube 24 is formed in the same cylindrical shape as the inflow porous tube 20 is installed in the axial direction of the main body, although not shown, the surface is formed in a net form. By allowing the outflow cross-sectional area formed in the outflow porous pipe 24 to be formed wider than the inflow cross-section of the inflow porous pipe 20, it is possible to stably secure the outflow flow rate and the flow rate, thereby reducing the head loss.

The upper and lower portions of the filter medium 26 are fixed by the filter medium fixing frame 28, respectively, but have a small flow due to the flow of inflow water or backwash water. Therefore, the outer thin media may block the hole of the outflow porous tube 24, by forming the surface of the outflow porous tube 24 in the form of a net to prevent this phenomenon.

Figure 3a is a front view showing a filter fixing frame in which the filter medium is installed, according to an embodiment of the present invention, Figure 3b is a partially enlarged cross-sectional view of FIG. According to Figure 3, the media fixing frame 28 is provided with a plurality of media fixing fixture 29 is fixed at regular intervals to fix the fiber yarn. Each mediator fixture 29 can be fixed to a plurality of fiber yarns, it is possible to form as many layers as necessary according to the number of fiber yarns.

In addition, since the upper and lower portions of the filter medium 26 are fixed to the filter medium fixing frame 28, it is possible to easily remove or replace the main body 10 without installing a separate housing.

Figure 4 is a cross-sectional view showing the inner cross-section of the main body of the cartridge-type water treatment filtration device is installed, in accordance with a preferred embodiment of the present invention. According to FIG. 4, the wired guide plate 34 may be alternately installed at upper and lower portions of the main body 10.

If there is an obstacle in the flow direction, the fluid flows along the surface, so that the inflow source water introduced into the main body 10 through the inflow porous pipe 20 by installing the streamline induction plate 34 is the outflow porous pipe. Through 24, it is possible to control the flow up to outflow. That is, by installing the wired guide plate 34 without installing a separate control device, the flow rate and direction of the inflowed water can be controlled appropriately, and thus the contact frequency of the suspended solids and the media 26 contained in the inflowed water is controlled. By increasing the quality of the final treated water can be further improved.
