Description

Sanitation facilities of early rainfall}

The present invention relates to an initial excellent purification treatment apparatus, and more particularly to an initial excellent treatment facility having an improved structure.

Large roads and residential aisles are usually provided with drains and drainage pipes that discharge rainwater into the rivers to prevent rainwater from pooling on the roads during rainfall. It is desirable to install rainwater treatment facilities for the rapid and large-scale purification of furnace contaminants mixed in the furnace. These devices differ from the technical idea of the wastewater purification system. Call it Chi.

At present, the water shortage is occurring all over the world, and Korea is expected to enter this phase in the near future. From now on, in order to solve the water shortage, efficient water management, securing and utilization should be taken. In order to solve the water shortage phenomenon, the method of efficiently using the rain that falls naturally is the best way to have various research and development.

However, this rainwater can be installed inexpensively and quickly and largely by removing various pollutants in the air or fallen leaves or trash accumulated on the surface and draining them into the rivers. In the early rainwater treatment facilities, there is a need for rainwater purification facilities to improve water quality of the rivers.

In general, pollutants include point pollutants and agricultural land, pastures, forest lands, construction sites, mines, logging sites, waste disposal plants, wastes, etc., which are discharged from defined and limited point sources such as rainwater, industrial wastes, and livestock wastes. Discharge areas such as landfills, urban areas, roads, and industrial sites can be divided into nonpoint pollutants emitted from a wide range of nonpoint sources. Contaminants emitted from these sources are heavy metals, pathogenic microorganisms, organic compounds, and radioactive materials. It is distributed in various forms such as substances, toxic substances and other salts. Pollutants are usually swept away by rainwater and flow into the public waters such as rivers, bays and lakes, or underground water, causing water pollution. And the destruction of the ecosystem resulting from this, and eventually to the human To be dropped.

Conventional early rainwater treatment facilities simply had a filter cartridge installed in a drain pipe to filter out contaminants contained in rainwater. In this case, since rainwater continuously passes through the filter cartridge, its capacity is limited. In case of heavy rainfall or heavy rain with heavy rainfall, there was a problem that a backflow phenomenon caused by overload occurred.

In case of point pollutants with a clear discharge point among the above-mentioned pollutants, a separate purification device or wastewater treatment facility is installed in homes, factories, livestock farms, etc. In addition, the discharge area is not only extensive but mostly remains on the surface of the earth, but it is the main cause of water pollution by entering the public water or groundwater such as rivers, bays and lakes with rainwater during rainy weather. In the rainy season, especially during the early rain, the rainwater flows into public waters such as rivers, bays, and lakes, or underground water, so the initial rainwater containing non-point pollutants is purified and flowed into public waters or ground water such as rivers, bays, and lakes. This is called an initial excellent purification treatment device.

Hereinafter, a detailed example of each configuration and its operation will be described with reference to an operation state diagram of the initial storm water treatment facility of the present invention shown in FIG. 4, which is the most preferred embodiment of the present invention. In addition, the thick arrow of FIG. 4 indicates the flow of sewage, and the ceiling surface of each drawing is omitted so that the main configuration of the inside may be understood, and thus, the ceiling surface is actually sealed up to the ceiling surface.

1 is a configuration diagram of the initial storm water treatment facility of the present invention.

As shown in FIG. 1, the initial rainwater treatment facility of the present invention is mixed with rainfall or leachate on the surface of fallen leaves or garbage (hereinafter collectively referred to as “sewage”) and streams through discharge facilities such as streams or sewers. As an excellent treatment facility installed between the inflow port 140 and the outflow port 150, the wastewater flows out as an initial treatment facility when it flows out, the sewage flowing into the inlet 140 is the first sedimentation tank 110. In the drawings, although shown in the hexahedron, the specification and shape, etc. are not specified, but may be a cube that can hold more than a predetermined capacity of sewage, the sedimentation tank 110 is to restrain the sewage flowing into the torrent By reducing the flow rate, it filters out fallen leaves floating in the sewage, and functions as a reservoir to sink debris with a specific gravity greater than water. . Therefore, in the settling tank 110, if the screening net formed with the body 111 is installed or has a structure that lowers the flow rate, it is preferable to increase the function of filtering and settling. In addition, if the sedimentation tank 110 is injected evenly spread on the bottom surface when the sedimentary stone (輕 比重 石; 115) is injected evenly, when the sewage less flows in contact with the falling sewage, but the sewage is introduced into the sedimentary stone (115 ) Has a lot of bubble perforations, lighter than water floats in the sewage and floats and the falling sewage will pass through the guard stone 115, that is, all sewage passes through the guard stone (115) regardless of the inflow of sewage It is more desirable to cause aeration (爆 氣) action to help the purification of sewage.

In addition, the sewage filtered primarily from the settling tank 110 flows into the filtering tank 120 to be purified secondary, the filtering tank 120 is partitioned into the settling tank 110 and the first partition wall 113, The first tunnel 114, which is the lower portion of the first partition 113, communicates with most of the interior thereof, and the infiltration filter 121a occupies most of the first purified water to penetrate through the lower portion of the filter 121a. As it enters, it is purified second through its porous layer. Of course, the size and shape of the trap 120 may also be properly adjusted and installed according to the installation capacity or the object to be purified. In addition, the filter 121a, which is the unit unit 121 having the structure shown in the drawing, is introduced through a plurality of small pores formed in the porous filter 121a, and the sewage flowing in from the side flows into the central hole 121b. The water is collected at the upper portion of the 120 and then flows back into the central perforation 121b of the filter 121a stacked next to the filter 120a and flows out to the water collecting tank 130 through the filter 121a side.

 Finally, the sewage (purified in the state that is already comparable to that of purified water) in the filter tank 120 is discharged to the collection tank 130 partitioned by the partition wall 123, and the collection tank 130 is also a collection tank By passing through the second tunnel 124 perforated to the lower end of the partitioned second partition 123 and 120, the filter flows through the filter 121a side of the filter tank 120, so no matter how flowing the inflow It is controlled by the flow and collected in the sump tank 130 once again fine suspended solids, etc. are precipitated and the purified sewage is discharged through the drain hole 150 drilled on the other bottom.

Figure 2 is another configuration of the initial storm water treatment facility of the present invention.

This installs a monthly inlet 141 on one side of the sedimentation tank 110 to improve efficiency compared to FIG. 1 and bypasses the sewage purified first in the sedimentation tank 110 through the monthly inlet 141. It is to be drained through, the wall outlet 151 to communicate with the bypass passage 160 and the sump tank 130 to collect all the sewage purified from the sump tank 130 to be discharged through one drain 150 Alternatively, the bypass 160 may be installed separately from the wall outlet 151, which is a separate pipe from the drain 150, and may be discharged through the separate outlet, in which case an individual wall outlet 151 may be installed to communicate with it. It is easy to install a treatment device (not shown) of this, it is good to be able to treat the sewage passing through the bypass path 160 to a more purified water, by adding a separate bypass path 160 in this way suddenly during heavy rain Blown Oh In the mass can be discharged it is preferable to prevent paesaek caused by the excellent treatment facilities even during heavy rain.

In addition, the monthly inlet 141, which is the inlet of the bypass passage 160, is formed at one upper end of the sedimentation tank 110, and is not used in the treatment of normal sewage. Overflow only when it fills enough to fill the overflow, this time, because the sewage is less polluted than the normal state due to the heavy rain of the incoming large quantity of water through the bypass 160 Discharge of sewage from which only sediments and sediments are removed does not cause a big problem.

Figure 3 is another configuration of the initial storm treatment facility of the present invention.

According to the preferred embodiment shown, the nasal pumice 115 for aeration is injected into the sedimentation tank 110, which is a sewage falling on the floor when a small amount of sewage inflow of the nasal pumice 115 floats in water. By preventing the pit, while preventing the porch, the porous nasal stone 115 causes aeration to help the purification of sewage, and a large amount of sewage is injected into the sedimentation tank 110 to rise to a certain degree to rise to the sewage Only, for example, it spreads over two floors and floats, so that aeration and filtering can be performed. The outflow outlet 151 and the drain 150 flowing out of the bypass passage 160 are provided in the treatment facility 100. It is configured to coalesce from the outside to simplify the pipe to be discharged to the river or river through the unified drain 150, pipe bottom of the inlet 141 Steps 142 slightly protruding toward the throw 160 are formed so that the sewage overflowing to the monthly inlet 141 is separated from the wall by the step 142 and falls down from the wall, thereby allowing the sewage to be damaged as a flow through the wall. By preventing it to be able to achieve aeration during the drop while maintaining durability.

4 is another configuration of the initial storm water treatment facility of the present invention.

This structure shows the most preferred embodiment, the adsorption filter 112 is further installed just before the month inlet 151 of the settling tank 110, through which the secondary filtering (Filtering) is possible, and more Preferably, the wall outlet 151 is formed separately from the drain 150 so as to treat the less purified sewage discharged therefrom as a separate device.

In addition, the permeable filter 121a installed in the filter tank 120 is a porous stone or foam block filter having a central perforated 121b having a cylindrical perforated shape. If cut into quarters or cut into quarters in the form of unit unit 121, it is preferable to be installed to be applied to a variety of standards in a laminated assembly type, and to put the gravel or other filter material in the center perforation (121b) part 2 The filter 121c is preferable because the filter 121c can be purged according to the nature of the sewage.
