The present invention relates to an apparatus for purifying contaminated water by separating contaminants from contaminated water mixed with contaminants, and more particularly, by using various types of filters, various kinds of contaminants are sequentially separated from contaminated water. The present invention relates to a manhole mounting purifier that effectively reduces water pollution and effectively prevents contaminated water from flowing back to the ground when water is not easily drained to the lower side of the chamber.

In general, water pollution sources are divided into point sources and nonpoint sources for the convenience of prevention and management. Point sources refer to pollutants from which wastewater containing contaminants are discharged from sewers or ditches at specific locations, such as sewage plants, wastewater treatment plants, power plants, waste mines, oil tanks, oil wells, etc., and nonpoint sources are large areas scattered all over the place. Pollutants are emitted from the forests, urban areas, construction sites, parking lots, roads, etc., which cause pollutants accumulated on the surface of rivers and the sea to cause pollution. Occurs when snow melts.

In addition, there are various kinds of pollutants depending on the type of pollutant. Examples of such pollutants include various garbage such as cigarette butts and fallen leaves, and particulate pollutants such as mud and soil, and particulate matter simply mixed with water and moving. Oils or fats that are not dissolved in water but are suspended in water and move with water, and soluble materials that are dissolved in water or colloidal and move with water.

1 is a diagram relating to the size and properties of particles in water.

As shown in FIG. 1, in general, particles which are not easily precipitated in water are classified more specifically according to size, and molecularly soluble materials of 1 nm or less, colloidal materials of 1 nm to 1 μm, and suspended solids of 1 μm or more. In particular, the suspended solids are more specifically classified into fine grain suspensions having a size of 1 μm to 10 μm and granulated suspending materials having a size of 10 μm to 100 μm.

Soluble substance is a generic name of substance dissolved in water among sewage-containing substances. It is composed of organic and inorganic substances. Colloidal substance is an intermediate between soluble substance and suspended solids, and plays an important role in sewage pollution. Suspended solids, which are substances of, generally refer to particles that are insoluble in water with a diameter of 1㎛ ~ 2mm or less, and are classified into fine suspended particles which cannot be precipitated and granulated suspended materials that can settle and cause turbidity. Therefore, when the suspended solids are discharged to natural waters such as rivers and seas, they contaminate natural water quality such as increasing turbidity of the water and fouling its appearance, making it a prominent indicator of water pollution.

In addition, since the soluble substance cannot be separated by filtration, it cannot but be removed chemically and biologically by advanced treatment, but the suspended solids are also removed by precipitation or flocculation and adsorption of activated sludge, which is a potent indicator of contamination. If the suspended solids and colloidal substances are removed by physical methods such as filtration, it is possible to maintain a cleaner water quality.

Therefore, where a purifier for purifying contaminated water is to be installed, a purifier must be installed with a contaminated water purifying filter for purifying specific contaminants depending on the type of contaminant, and generally flows into a manhole. Since the contaminated water is mostly contaminated by the above-mentioned nonpoint source, it should be properly installed accordingly.

Registered Utility Model Publication No. 20-0167090 (Name: Roadside sewage filter mechanism) has a sidewall and a bottom surface and uses at least one filter formed of a network structure, and smokes cigarettes or fallen leaves floating with the sewage to the sewer pits on the roadside. In addition, by filtering other wastes to prevent flow into the sewer pipe, a technique for preventing contamination of groundwater or rivers, as well as preventing waste from building up in the sewer pipes and narrowing or clogging the waste water pipes is disclosed.

In addition, the Utility Model Publication No. 20-0303595 (name: manhole drain pipe blockage prevention device) and the inlet of the drain pipe penetrates the bottom surface and is formed to protrude therein, the foreign matter flowing into the manhole is introduced into the drain pipe Filtration means for preventing the formation, and a discharge port is formed at the upper end and the boss for receiving the protrusion of the drain pipe is formed in the center and the inner cylinder is retractable in the outer cylinder, the foreign matter flowing into the manhole filtration formed at the inlet side of the drain pipe A technique is disclosed in which the drainage pipe is blocked and unnecessary to replace with a new one by preventing the inflow into the drainage pipe by means.

However, these conventional contaminated water purifiers can separate some of the larger particles of dirt, such as cigarette butts, leaves, and other wastes, but the relatively small particles of soil or most of the suspended solids are allowed to flow into the sewer. The contaminated water containing the suspended solids flows into rivers and the like along sewage pipes. Accordingly, when the suspended solids flow into the rivers and the like along the sewer pipes, various kinds of water pollution occur, and the inflow of contaminated water increases during the rainy season or other heavy rains, or due to deterioration of the filter due to contaminants such as sludge. If the drainage does not proceed smoothly, but rather to flow back to the ground also causes a problem that causes another pollution of the ground.

The present invention has been invented to solve the conventional problems as described above, the purpose of providing a technology that can be effectively applied to the removal of various contaminants by separating the contaminants sequentially by providing filters to play different roles. It is done.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment according to the present invention will be described in more detail.

2 is an exploded perspective view of a manhole mounting purifier according to an embodiment of the present invention, Figure 3 is a cross-sectional view of a manhole mounting purifier according to an embodiment of the present invention.

As shown in Figure 2 and 3, the manhole mounting purifier according to an embodiment of the present invention comprises a first filter 20, the second filter 30, the chamber 40 and the like.

The first filter 20 is mounted inside the chamber 40 to primarily filter particulate contaminants in the contaminated water introduced into the manhole. More specifically, the first filter 20 has a protrusion 21 formed at the center thereof, and the protrusion 21 has a mesh shape.

The second filter 30 is disposed below the first filter 20 and secondarily filters contaminants that are not filtered through the first filter 20. In more detail, the second filter 30 is mounted to include activated carbon.

The chamber 40 has the first filter 20 and the second filter 30 mounted therein, and contaminated water introduced from the upper side through the manhole cover has passed through the first filter 20 and the second filter 30. After passing through), let it discharge downward. More specifically, the lower side has a porous plate 44 to facilitate the drainage of contaminated water, the width is formed narrower than the width of the manhole, at least one discharge on the upper side of the second filter (30) A ball 42 is formed, and the outlet hole 42 has an extended opening so that the upper side thereof corresponds to the manhole cover.

In addition, the chamber 40 includes a first support part 41 for supporting the first filter 20 and a second support part 43 for supporting the second filter 30. The first support part 41 supports the first filter 20 and the second support part 43 supports the second filter 30, as well as the chamber and the first filter 20. And it is to be able to be removable with the second filter 30 to facilitate the cleaning. In addition, the shape of the chamber 40 is a flat cross-sectional shape, but the shape may be any other shape, regardless of the cylindrical shape or any other specific shape.

4 is an operational state diagram related to the manhole mounting purifier according to the embodiment of the present invention. In more detail, it is a state diagram regarding the operation of the first filter 20.

In general, pollutants coming through the manhole come with large particles of dirt, such as cigarette butts, leaves, and other wastes, including soil and other suspended substances. Therefore, as shown in FIG. 4, the first filter 20 allows dirt, such as rubbish, to accumulate large particles on the bottom of the first filter 20, and the particulate suspended solids are mesh-like protrusions 21. In addition to the primary purification of the contaminated water by the primary filter in), the particulate contaminants prevent the drain pipe connected to the manhole from being blocked. In addition, the protruding portion 21 may have a different shape regardless of the shape of a cylindrical shape, a rectangular parallelepiped shape, or a conical shape, and may be appropriate so that contaminants may not be easily accumulated and contaminated water may not be easily discharged. You will have to maintain the height. If dirt accumulates, the first filter 20 is lifted to remove dirt and clean it.

5 is another operation state diagram of the manhole mounting purifier according to the embodiment of the present invention. In more detail, it is a state diagram regarding the operation of the second filter 30.

Activated carbon is carbonaceous and most of the constituents are adsorptive, so it is mostly used as an adsorbent. Generally, activated carbon is used for various liquid purification such as water treatment, food, beverage, and medicine processing. Therefore, as shown in FIG. 5, the second filter 30 filters secondly the liquid contaminants such as the suspended solids and the oil or oil, or the colloidal contaminants, which are not filtered by the first filter 20. By further improving the purification of contaminated water. In addition, the second filter 30 lifts the first filter 20, takes out the second filter 30, and maintains and manages it by cleaning or replacing.

6 is still another operational state diagram of a manhole mounting purifier according to the embodiment of the present invention. More specifically, it is a state diagram regarding the action in the chamber when the inflow of contaminated water is rapidly increased.

Since the second filter 30 filters oil, oils, oils, and the like, the discharge rate of the second filter 30 is lower than that of the contaminated water flowing through the first filter 20. Therefore, although there is no problem in the drainage in normal times, if the inflow of contaminated water is rapidly increased due to the rainy season or a sudden heavy rain, the discharge rate drained by the second filter 30 is more than the inflow rate of the contaminated water is introduced. Slow cases may occur. Therefore, as shown in FIG. 6, when the drain hole 42 is not easily drained to the lower side of the chamber 40 as described above, the contaminated water is discharged to the side of the chamber 40 so that the contaminated water does not flow back to the ground. In order to form the upper side of the second filter (30). (Recall that backwashing of contaminated water causes another pollution of the ground.) In addition, the opening of the upper side of the discharge hole 42 to correspond to the manhole cover is usually contaminated water flowing through the manhole cover. At the same time, when the inflow rate of the contaminated water increases rapidly, the outlet hole is formed so that the contaminated water escapes through the discharge hole 42 by leaving a space between the side wall of the manhole and the chamber 40. This is to prevent backflow to the ground.

Although the above has been described with reference to the preferred embodiment according to the present invention, those skilled in the art to which the present invention pertains can be carried out by other specific forms of example without changing the technical spirit or essential features of the present invention. I can understand. Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all aspects.
