The present invention not only filters sewage and sewage efficiently, but also relates to a filtration device for sewage and sewage, which is very convenient to manage the filter material contained therein.

In addition to the increase in population, industrialization and the improvement of people's living standards, organic matter, nitrogen, phosphorus, etc. It contains a large amount, and various pathogenic bacteria are easy to culture.

Therefore, it is preferable that such various kinds of living sewage are discharged to rivers or public waters after being purified to remove organic matter, nitrogen, phosphorus, etc. to below the allowable level. However, it is a reality that various kinds of living sewage are discharged to rivers or public waters as they are, without increasing the level of water pollution.

In Korea, only 39% of total sewage is discharged into rivers or public waters after being purified at sewage treatment plants, and the remaining 61% is discharged as it is. The reason is that the sewer pipe network, which starts from each home, reaches the sewage treatment plant through the drainage pipe is not properly installed.

Considering the reality of Korea, the filtration device which is easy to install and easy to manage is used to remove organic matter, nitrogen, phosphorus, etc. contained in sewage and sewage in each area where sewage and sewage is not purified and discharged in large quantities. It would be desirable.

Filter devices for purifying sewage and sewage have been known and used in the past.

The most widely used among them is digging a pond, covering the puddle with an impervious mat, and then filling the gravel to form a filtration layer, the inlet sump and inlet pipes on the upper side of the filtration layer below the filtration layer. Field and discharge basin, and the upper part of the filtration layer is a filtration device to fill the soil back to form the soil layer.

Such a conventional filtration device distributes sewage and sewage to the inflow sump and inflow pipes, and collects through the sump pipes and the discharge sump embedded in the lower part of the filtration layer, and then discharges it to purify the sewage and sewage. Play a role of

However, in the conventional filtration apparatus, first, since the air was not injected efficiently, the growth activity of the aerobic fungi inhabiting the filter media was not strong, and there was a defect that the efficiency of the removal of organic matters was lowered.

Second, when the gap between the filter media is blocked and the original filtration function is not properly performed, the soil layer formed on the upper part of the filter media needs to be dug again to replace the filter media. There was a defect that was not easy to maintain.

An object of the present invention is to provide a filtration device for sewage and sewage to increase the efficiency of removing organic matter by encouraging the bioavailability of aerobic fungi inhabited by attaching air to the filter media by efficiently injecting air; Second, it is possible to selectively replace only a portion of the filter media when the filter media is not performing the original filtration function, reducing the burden of filter media replacement, easy to maintain and manage sewage and sewage Is in providing.

Hereinafter, the technical configuration of the present invention in detail.

Sewage and sewage filtration apparatus of the present invention, as shown in Figures 1 and 2, both side wall portions extending upward from both ends of the bottom plate portion 114 is formed with a bottom groove 112 in the longitudinal direction of the center of the upper surface ( A water pipe 110 having 116a and 116b, a support plate 120 covered at the top of the bottom plate part 114 and having plate holes 129 drilled therein, and a bottom groove 112 at the bottom of the support plate 120. And an inlet network 140 and an outlet network 150 installed on the front and rear ends of the water pipe 110, the diffuser 130 through which the tube holes 139 are drilled, and the both side wall portions. In the cover plate 170 for opening and closing the upper portion of the 116a, 116b and the filter material 160 is filled in the space formed on the upper support plate 120 inside the water pipe 110, the water pipe 110 Passage having a size enough to allow water to pass through without passing the filter medium 160 at appropriate intervals therein Holes 149 are installed through the yoke 149, and the pipe holes 139 formed in the diffuser 130 have a smaller diameter as they are adjacent to the air compressor, and a larger diameter as they are farther. It is characterized by the technical configuration.

The present invention configured as described above is installed so that the sewage and sewage is discharged through the outlet network 150 after passing through the inlet network 140 of the water pipe 110, the air diffuser (not shown) in the diffuser 130 Is used in conjunction.

The present invention, first, by operating the air compressor (not shown) to inject air into the bottom plate portion 114 of the water pipe 110 through the pipe hole 139 of the diffuser 130, the plate of the support plate 120 The holes 129 diffuse through the gaps of the filter media 160 and are attached to the filter media to promote the growth activity of the aerobic fungi inhabiting. Therefore, it has an effect of increasing the removal efficiency of organic matter contained in sewage and sewage through the growth activity of aerobic fungi.

Second, when the sludge accumulates in the gap of the filter mediums, and the filter mediums do not properly perform the original filtration function, the filter medium 160 is partitioned and filled in a limited number of spaces because the water separator is installed in the water pipe 110. Among them, since the filter medium 160 in a state in which the filtration function is deteriorated can be selectively replaced in the space, it will have an effect of significantly reducing the burden caused by replacing the filter medium 160.

In this embodiment, the water pipe 110 may be made of ready-made concrete or cast-in-place concrete, or may be made of synthetic resin or other various materials. The water pipe 110 has a bottom plate portion 114 in which the bottom groove 112 is recessed in the longitudinal direction on its upper surface and both side wall portions 116a and 116b extending upward from both ends of the bottom plate portion 114. It is preferable that the bottom plate portion 114 is formed to be inclined downward from the inlet side to the outlet side. The top surface of the bottom plate 114, as shown in Figure 3, the bottom groove 112 is recessed in the longitudinal direction in the middle portion thereof, and the bottom groove 112 is located on both sides of the bottom groove 112 Both inclined surfaces 115a and 115b are inclined downward.

In addition, a supporting plate 120 through which the plate holes 129 are drilled is placed on the upper sides of the inclined surfaces 115a and 115b of the bottom plate 114. The support plate 120 forms a bottom boundary surface of the filter media 160, thereby forming a space between the filter media 160 and the top surface of the bottom plate 114. Sludge generated during the filtration process of contaminated sewage and sewage falls down through the plate holes 129 of the backing plate 120, and then flows down on both side slopes 115a and 115b of the bottom plate 114 to flow down. Are gathered to 112.

The bottom groove 112 is provided with an diffuser 130 to be connected to an air compressor (not shown) installed outside the water pipe 110. The air supplied from the air compressor is supplied to the gap between the filter mediums 160 through the plate holes 129 of the support plate 120 via the pipe holes 139 formed in the diffuser 130, thereby filtering the filter medium ( 160) to support the growth of aerobic fungi inhabiting them.

The pipe holes 139 formed in the diffuser 130 are smaller in diameter as they are adjacent to the air compressor, as shown in FIG. This helps to spread the air supplied from the air compressor evenly through the gaps of the filter media 160.

The cover plate 170 serves to cover the upper portion of the water pipe 110 by supporting both side ends of the stepped portions 118 formed in the longitudinal direction inside the upper sides of the side wall portions 116a and 116b. The cover plate 170 may be made of a material such as synthetic resin or concrete, if necessary.

Connection bolts 171 are protruded to the stepped portions 118 and the cover plate 170 is fastened to the connection nuts 173 through the connection holes 179 that are opened in the cover plate 170. The fastening structure is illustrated. The fastening structure of the cover plate 170 facilitates the replacement work of the filter medium 160 by removing the cover plate 170 when replacing the filter medium 160, and usually connecting the cover plate 170 to the connection bolt ( 171 and the connection nut 173 are fixed to cover the upper portion of the water pipe 110 to prevent unnecessary foreign substances from entering the filter material 160 through the open upper portion of the water pipe 110. In addition, when the specific gravity of the filter medium 160 is floated in the water, the filter medium 160 also serves to prevent the filter material 160 from being lost to the upper portion of the water pipe 110.

The filter material 160 may be used separately, such as styropool (foamed polystyrene), waste tire pieces, artificial aggregate, or may be mixed.

Styrofoam (foamed polystyrene) and waste tires are not only easily obtained as waste materials themselves, but also used as wastewater and sewage filter media to filter nitrogen, phosphorus and organic matters. Conservation of water resources is more meaningful.

Artificial lightweight aggregate provides a good environment for microorganisms to live due to the many holes formed on the surface thereof, and is light and easy to handle.

Inside the water pipe 110, the filter media 160 are not passed at appropriate intervals, but water flow separators 145 through which water flow holes 149 are drilled are installed. The water separator partition plate 145 serves to allow the filter medium 160 to be contained in the limited space part so as to check the state of the filter medium 160 for each space part to perform a replacement operation.

Here, the water separator plate 145 is preferably installed at appropriate intervals in the longitudinal direction or the width direction for each space partitioned by one cover plate 170 as much as possible.

In addition, the sludge storage tank 310 is connected to the end portion of the water pipe (110). The bottom portion 313 of the sludge storage tank 310 is located below the bottom plate portion 114 of the water pipe 110 as shown in FIG. 6, and rides the bottom groove 112 of the bottom plate portion 114. Sludge 10 flowing down to be smoothly collected. Sludge collected at the bottom 313 of the sludge storage tank 310 is designed to be discharged to the outside through the sludge discharge pump (not shown).

The side walls of the sludge storage tank 310 are preferably formed by extending both side wall portions 116a and 116b of the water pipe 110 in the longitudinal direction, and the rear wall portion 314 is formed to be slightly lower than the water pipe 110. desirable. This is to prevent the river water filtered in the interior of the water pipe 110, such as shown in Figure 6 to flow over the rear wall of the sludge storage tank 310.

Meanwhile, FIGS. 7 and 8 show other embodiments of the present invention, and show an example in which a plurality of water pipes 110 are collected and installed in parallel. This can be used to install the water pipes 110 made of a ready-made product in parallel, so that the filter water 160 is contained in the limited space while allowing the large water to be filtered significantly. Here, both side wall portions 116a and 116b that the water pipes 110 are in contact with each other may be integrally manufactured as necessary.

In addition, Figures 7 and 8 shows an example in which the water pipe 110 in the filtration device of the present invention is installed by covering a plurality of cover plates 170 connected to the top. This is to show that the water pipe 110 may be manufactured by dividing into several pieces when the water pipe 110 is too long or wide to cover the entire upper portion of the water pipe 110 with one cover plate.

As described above, the sewage and sewage filtration apparatus of the present invention is attached to the filter medium to promote the growth activity of aerobic fungi inhabiting to increase the removal efficiency of organic matter contained in the sewage and sewage, sludge in the gap of the filter medium If the filter media do not properly perform the original filtration function due to the backlog, it is very useful to have the effect of selectively replacing only some of the filter media.
