Recently, the environmental problem has emerged as the most important part for humankind to solve, and considerable technological development is being made in each field. Among them, remarkable growth has been made in the water quality field, and technology development for filtration or purification of wastewater through screen devices is being actively performed. However, the conventional screen device is mainly used in the frame of the net, when a certain amount of foreign matter is removed, the network is clogged, there is an inconvenience that must be replaced from time to time because the performance is degraded or disturbs the flow of water. In order to alleviate this inconvenience, a technology is disclosed that can be used semi-permanently without replacing the screen by providing a separate removal device for removing the foreign matter filtered on the screen.

The wastewater filtration apparatus of FIG. 1 is disclosed in Korean Patent Publication No. 91-4233. This is provided with a rotating shaft (2) (20g) and a filter plate (4) of the porous hole 3 on the upper and lower sides of the square frame (1), and the chain gears (5) (50h) on both sides of the rotating shaft are connected to the chain (6). It connects and arranges the slider 7 at regular intervals between the chains 6, and the slider 7 can slide the surface of a filter plate by rotation of a chain. Therefore, the foreign matter filtered by the filter plate 4 is removed by the slider 7.

However, such a conventional wastewater filtration device is configured such that the slider 7 simply slides on the filter plate 4, thereby not sufficiently removing foreign matters caught by the filter plate 4, but also having a small solid or gel material. There is a risk of blocking the pores 3 of the filter plate 4. Therefore, when used for a long time there was a problem that you need to replace the filter plate or perform a separate cleaning.

However, the fishmeal removal device for fish farms, there is a problem that because the use of a very small non-woven fabric of the hole size, foreign matter to block the fine holes of the non-woven fabric using only a short time, the purified water does not pass through the non-woven fabric. In addition, since the whole nonwoven fabric is used, problems such as damage to or tangling of the nonwoven fabric occur when the nonwoven fabric is not tolerated and the foreign material such as tree branches is torn or caught. In addition, there is a problem that foreign substances filtered by the nonwoven fabric do not move continuously attached to the nonwoven fabric and slide down and accumulate downward. In addition, the wastewater filtration device and the fish meal removal device described above have a problem in that the whole installation work is very difficult and a part is damaged because a single filter plate and a nonwoven fabric are used as a whole. In addition, the separated foreign matter should be collected and discharged separately, but if it cannot be discharged for a long time, there was a problem that the separated foreign matter stuck to the device.

Therefore, the present invention is intended to solve this problem, and the main purpose of the present invention is to effectively separate the solid matter contained in the wastewater and the foreign matter in the gel state by using a plurality of divided screens and filtering the foreign matter over the first and second times. The present invention provides a wastewater filtration apparatus which can be safely transported and removed.
