Description

An apparatus for filtering waste water.

The present invention relates to a filtration device, and more specifically, it is possible to finely remove contaminants such as fine particles in the process of filtering purified water, sewage and waste water, etc., thereby providing a cleaner filtered water to maximize filtration efficiency. It relates to a filtration device that allows.

In general, a filtration device is used as one of the essential facilities in the treatment process of purified water, sewage, and waste water. A typical example of such a filtration device includes a sand filter, a cartridge filter, and a precoating filter ( pre-coating filters) are used.

The sand filter not only has a poor quality of the filtered filtrate, but also has a problem of low filtration efficiency, the cartridge filter can obtain the required quality of the filtered water, but backwashing is not possible, and the adaptability at high concentration There was a problem of having a low disadvantage, the pre-coating filter was also possible backwashing and the filtered water quality was very good, but the problem of low adaptability at high concentrations, frequent backwashing cycles, and expensive equipment costs Caused.

In order to improve this problem, as shown in FIG. 5, a depth filtration method is devised. The configuration of the inlet pipe 52 through which contaminated water to be filtered is introduced at the top of the body 50 is provided. ) Is installed, and a discharge pipe 54 for discharging filtered filtrate is installed at a lower end of the valve (not shown), and a plurality of inflow holes 62 are formed at an upper side of the body 50. The support body 64 is flowed by the water pressure introduced to the lower side, the fixing member 68 is coupled to the filtration membrane layer 60 of the fiber material connected to the support 64 is formed and fixed a plurality of discharge holes 66 Is configured to be installed.

The filtration method of the filtration device (1) configured as described above is the support 64 is installed in the body 50 by the water pressure of the contaminated water introduced through the inlet pipe 52 formed on the top of the body 50 and one dashed line and The support 64 through the inlet hole 62 formed in the support 64 while the filter membrane layer 60 of the fibrous material coupled between the support 64 and the fixture 68 is formed to overlap each other while descending downward as described above. And the filtered water filtered while the foreign matter contained in the contaminated water from the filter membrane layer 60 of the fibrous material overlapped with the plurality of layers while being introduced between the fixed body 68 and the filtrate filtered through the discharge hole 66 of the fixed body 68. After being discharged to the discharge pipe (54).

In the process of filtering foreign matters contained in the contaminated water in the filtration membrane layer 60, the microfiltration is formed between the filtration membrane layer 60 of the fibrous material as the support membrane 64 is lowered and overlapped with the support membrane 64 of the fibrous material. In this regard, foreign matters contained in the contaminated water pass through the micropores, and the foreign matters are filtered out.

When the filtration process is completed as described above and the foreign matter attached to the filtration membrane layer 60 is to be removed, air or filtered filtrate is injected into the discharge pipe 54 from which the filtrate was discharged, and thus, the fixed body is formed by air pressure or water pressure. The support 64, which has been lowered to the side of 68, is lifted upward in the body 50, and at the same time, the foreign material attached to the filtration membrane layer 60 of the fiber is separated by a slight vibration, and is lifted by air pressure or water pressure. It is discharged to the outside through the inlet pipe 52 through the inlet hole 62 of the support 64.

However, in the filtration device 1 used as described above, the water quality of the filtered filtration water is better than the sand filter, cartridge filter, and precoating filter, which are the aforementioned various filtration devices, and can be installed in a narrow space. In addition, the low-cost advantages, and the backwashing by air or water, there was a high backwashing efficiency and the advantage that the backwashing time is short, but the filtration membrane layer 60 of the fibrous material overlapping due to the support 64 lowered by hydraulic pressure ), The overlapped layers of the filtration membrane layer 60 have a low density of the fiber material, and the overlapped layers have a high density of the fiber material due to the high overlap of the fiber material. The contaminated water filtered through the low filtration membrane layer 60 was not filtered smoothly, resulting in a drop in filtration efficiency.

Accordingly, the present invention is designed to solve the above problems, and can finely remove contaminants such as fine particles in the process of filtering purified water, sewage, and wastewater, thereby providing a cleaner filtered water. The goal is to maximize efficiency.
