The height of the moonware 30 may be made of a height enough to grasp the rainfall of the rainwater flowing into the rain pipe 20 is less than 5mm. In other words, if the amount of rainwater flowing into the storm pipe 20 is collected less than 5mm to collect the rainwater in the rainwater region, the overflowware 30 can be formed at a height high enough to collect it. To protect the initial excellent treatment device. And the size of the pretreatment tank 100 to be described below is also set based on rainfall.

Next, the main body 10 which is an initial excellent processing apparatus is demonstrated.

The main body is largely composed of a pretreatment tank 100 and a filtration tank 200, and the pretreatment tank 100 and the filtration tank 200 are partitioned by a blocking wall 11 formed therein.

The body 10 may be configured to be located at the same depth as the rain pipe 20 or more than that. Or it may be installed in a deeper position than the rain pipe 20, where the reference of the same depth means the bottom bottom portion in the rain pipe 20 and the upper surface in the main body 10, the main body 10 is the rain pipe 20 Since it is located below the bottom of the bottom of the upper portion of the main body 20 is at least as high as the height of the rain pipe 20 is configured to utilize the ground layer of the upper body 10.

At this time, the initial excellent movement within the main body 10 is caused to flow by the water head difference (water height) which is the difference between the upstream and downstream water level. The inlet pipe 110 of the pretreatment tank 100 is formed higher in the head position than the outlet pipe 210 of the filtration tank 200 to move the initial excellent water by the head difference.

The initial excellent water collected by the overflowware 30 of the rain pipe 20 is guided to the pretreatment tank 100 of the main body 10 through the inflow pipe 110.

The pretreatment tank 100 is a storage facility that primarily separates coarse contaminants, floating substances, and sediments from the initial excellent water guided into the inlet pipe 110, and collects the contaminant collecting network 120 and the contaminant collecting network pedestal 130. , The first baffle plate 140, the multi-stage baffle 150, the bypass hole 160, and the manhole 170.

The catch trap network 120 collects relatively large contaminants such as coarse traps included in the initial rainwater flowing into the inflow pipe 110, and collects the traps by the weight of the traps captured in the trap capture network 120. In order to prevent the shape change of the 120, the lower part of the trap collecting net 120 is provided with a trap collecting net support 130 to support it.

The initial excellent water from which the contaminants are removed by the contaminant trapping network 120 is introduced into the multi-stage baffle 150 provided in the pretreatment tank 100.

Multi-stage baffle 150 is shown in Figure 6 of the accompanying drawings, a plurality of baffles (baffle) is provided therein by decelerating the flow of the initial excellent by changing the progress of the initial excellent by the baffle in the direction In order to filter out the suspended solids and sedimentary substances contained in the initial excellent water, the upper portion is provided with a float discharge port 155 for discharging the suspended matter, the lower portion is provided with a sediment discharge port 157 for discharging the sediment.

In more detail, the multi-stage baffle 150 has a first stage baffle 151 having an upper surface open and a lower portion of a surface facing the first stage baffle 151, and a portion of a lower side of the first stage baffle 151. A second end baffle 152 in communication with the opening and having a part of an upper side of the surface facing the communicating surface, and a part of the upper side of the second end baffle 152 communicating with the open side; It is composed of a third stage baffle 153 having an outlet 154 in communication with the filtration tank 200 at the lower side of the surface facing the discharge outlet is discharged.

In addition, the multi-stage baffle 150 may be configured by speaking a plurality of second stage baffles 152 located at the first stage baffle 151 and the third stage baffle 153.

The initial excellent water introduced into the pretreatment tank 100 is filtered through the contaminant trapping network 120 and is gradually accommodated in the pretreatment tank 100 to raise the water level, and the water level is the first stage baffle 151 of the multi-stage baffle 150. Inflow to the first stage baffle 151 of the multi-stage baffle 150 and passes through the first stage baffle 151, the second stage baffle 152 and the third stage baffle 153. While the flow rate is significantly reduced inside the multi-stage baffle 150, the suspended matter is gathered to the top of the multi-stage baffle 150, and the sediment is collected to the bottom of the multi-stage baffle 150.

Thus, as a configuration for discharging each of the floats and sediment from the multi-stage baffle 150, the upper surface of the multi-stage baffle 150 is provided with a float discharge port 155 for discharging the floating material, the lower side of the sediment is discharged sediment The discharge port 157 is provided, the suspended matter is collected in the upper portion of the pretreatment tank 100, and the precipitate is accumulated in the lower portion of the pretreatment tank 100.

Compartment. Therefore, the suspended matter discharged from the multi-stage baffle 150 is collected only on the upper portion of the multi-stage baffle 150 by the first baffle plate 140.

In addition, the multi-stage baffle 150 is provided with a reverse side 159 that communicates with the filtration tank 200 by the operation at the lower portion thereof and introduces the initial superiority of the filtration tank 200 into the pretreatment tank 100. The ground side 159 is configured to receive water from the filtration tank 200 and to clean the inside of the pretreatment tank 100.

That is, the pretreatment tank 100 and the filtration tank 200 may be cleaned to maintain the purification rate of the contaminants and fine contaminants in the initial excellent water, if necessary, in the dry season or as necessary, and the water contained in the pretreatment tank 100 and the filtration tank 200 may be removed. Using a separate pump (not shown in the figure) to drain and clean the pretreatment tank 100 with the remaining rainwater is configured to guide and clean the relatively purified water of the filtration tank 200 to the pretreatment tank 100. .

That is, the coarse coarse matter is collected by the contaminant trapping network 120, and the float and the sediment are filtered by the multistage baffle 150 to the upper and lower portions of the multistage baffle 150, respectively. In particular, the suspended solids filtered by the multi-stage baffle 150 are collected in a predetermined area by the first baffle plate 140 to prevent re-injection of the suspended solids filtered during the initial excellent treatment.

The contaminant trapping network 120 of the pretreatment tank 100 has a limit capable of processing the amount of rainwater flowing into the inlet pipe 110. In this case, the trapping material trap 120 may be blocked by the incoming fines of the initial trap, and the initial rainwater to be treated as the blockage of the trapping trap 120 may not be introduced into the pretreatment tank 100, and the excellent pipe 20 may be blocked. Can be transferred downstream. Accordingly, the pre-treatment tank 100 receives the initial excellent water introduced into the inlet pipe 110 at the time of closing the contaminant trapping network 120 in order to introduce the maximum initial excellent amount that the initial excellent water treatment apparatus of the present invention can accommodate. Bypass hole 160 to be introduced directly into is installed.

The bypass hole 160 is configured to directly input the initial excellent water introduced into the pretreatment tank 100 by a predetermined height higher than the height of the contaminant collecting network 120.

The pretreatment tank connected to the inlet pipe 110 for the management of the complex trapping network 120 and the bypass hole 160, and only the initial excellent water flowing from the rain pipe 20 to the upper portion of the pretreatment tank 100. The upper portion of the 100 is further provided with a manhole 170 protruding on the ground. In particular, the manhole 170 protects the contaminant collecting network 120 and the bypass hole 160, protrudes from the surface to a certain height to prevent a safety accident, and the inside of the pretreatment tank 100 therein. A ladder 171 or the like for entering may be installed and configured to be provided with a manhole cover 172 at the top thereof to be managed.

The ladder 171 is configured to reach the bottom of the pretreatment tank 100, the manhole cover 172 may be provided with a locking device (not shown in the figure).

On the other hand, in the pretreatment tank 100, the initial excellent water filtered contaminants, suspended matter and sediment is introduced into the filtration tank 200.

The filtration tank 200 is installed parallel to the rain pipe 20 is installed underground, and the inner bottom of the filtration tank 200 is configured to be higher than the inner bottom of the pretreatment tank 100.

The filtration tank 200 has a plurality of fiber filter media 220 for adsorbing / filtration of the fine contaminants contained in the initial excellent and the excellent excellent water 20 is the excellent contaminants adsorbed / filtered by the fiber filter medium (20) Outflow pipe 210 for discharging to is installed.

The height of the outflow pipe 210 installed in the filtration tank 200 is lower than the free surface height of the inflow pipe 110 installed in the pretreatment tank 100 and introduced into the pretreatment tank 100 through the inflow pipe 110. The initial rainwater is naturally introduced into the filtration tank 200 and configured to be discharged through the outflow pipe 210, wherein the initial rainwater introduced into the pretreatment tank 100 almost fills the internal space of the pretreatment tank 100 ( In the state immediately before saturation) is transferred to the filtration tank 200 and the initial excellent water introduced into the filtration tank 200 is discharged through the outlet pipe 210 in the state filled with all the internal space of the filtration tank 200.

At this time, the principle of the initial excellent water is transferred from the pre-treatment tank 100 to the filtration tank 200 is transferred to the invert siphon principle can be installed in the same or lower ground than the bottom of the rain pipe (20) pre-treatment tank (100) ) And the upper part of the filtration tank 200 may be utilized.

That is, the inlet pipe 110 is installed to be located higher than the outlet pipe 210, the initial rainwater is introduced into the inlet pipe 110 is first accommodated in the pretreatment tank 100, the received initial rainwater to the filter tank 200 It is filtered by the inlet, the initial excellent water filtered in the filter tank 200 by the water pressure of the initial excellent water received in the pretreatment tank 100 is made by the history-funded principle discharged through the outlet pipe (210). Accordingly, the initial excellent treatment apparatus of the present invention according to the principle of inverse-fun can use the entire internal space of the pretreatment tank 100 and the filtration tank 200, and thus, the internal excellent treatment apparatus may have an internal structure than the conventional initial excellent treatment apparatus made by the siphon principle. High utilization of space has the advantage of reducing the volume of the structure.

According to this, since the entire area of the internal space of the pretreatment tank 100 and the filtration tank 200 according to the history-funn principle can be utilized, the initial excellent treatment capacity is improved than the conventional initial excellent treatment apparatus of the same size.

The initial excellent treatment apparatus of the present invention requires very small device area, and by installing the initial excellent treatment apparatus under the side of the rain pipe, the artificial structures protruding on the surface are minimized so as not to damage the surrounding landscape and the underground buried material on the side of the rain pipe. It can be used as a space to install.

Fiber filter medium 220 provided in the filtration tank 200 is to adsorb / filter the microcontaminants contained in the initial excellent, it is composed of a plurality.

At this time, since the initial excellent water is accommodated in all the inner space of the filtration tank 200, the height of the fiber filter material 220 is produced to the height of the filtration tank 200, one row provided with a plurality of the fiber filter material 220 is a filter tank Installed in the longitudinal direction of the (200) is installed so as to separate the filtration tank 200 into two compartments is configured to contact at least one or more initial rainwater moved from the pretreatment tank 100 at least once. .

7 of the accompanying drawings, the fiber yarn filter 220 is shown, and includes a frame 221 for fixing the fiber yarn and a fiber yarn 222 installed on the frame 221. A feature of the fiber yarn material 220 is to combine the advantages of the stationary type and the flow type, but the material of the fiber yarn 222 is made to form a myriad of rings made of polypropylene made of high microfiber. The fiber yarn 222 is freely flowed according to the initial excellent flow, so that microorganisms naturally attach and detach, and thus, microorganisms naturally occur because excessive attachment and desorption of microorganisms does not occur in the initial excellent water accommodated in the filtration tank 200. The cleaning cycle can be considerably longer without removing it. As a result, management costs are lower and management procedures are considerably easier.

The fiber yarn 222 will be described in more detail. The fiber yarn 222 is made of polypropylene 800 denier, which greatly increases the contact area, and is excellent in resistance and tensile strength. In this way, aerobic and anaerobic microorganisms are grown in this fiber yarn 222 in a balanced manner to adsorb and decompose organic matter, and remove nitrogen (N) and phosphorus (P), which are difficult-to-dissolve BOD substances.

One row provided with a plurality of fiber filter materials 220 is installed in the longitudinal direction of the filtration tank 200 to separate the filtration tank 200 into two compartments in the multi-stage baffle 150 of the pretreatment tank 100. The discharged initial rainwater flows into the pre-filtration zone 201 of the filtration tank 200 and passes through the fiber filter media 220 to the post-filtration zone 202.

In order to clean the filtration tank 200 together with the pretreatment tank 100, a cleaning worker should be able to freely travel between the pre-filtration zone 201 and the post-filtration zone 202. The door 230 may be provided to access the rear zone 202 by opening and closing the rear zone 202.

Filtration tank 200 may be introduced into the initial rainwater to remove the impurities, suspended matter and sediment to some extent by the complex trapping network 120 and the multi-stage baffle 150 of the pretreatment tank 100 may include fine suspended matter and residual sediment. In this case, the precipitate included in the initial excellent water is precipitated in the filtration tank 200 and stacked on the bottom of the filtration tank 200, but fine suspended matter may flow out to the rain pipe 20 through the outlet pipe 210. In order to prevent this, the second baffle plate partitioning a part from the upper part of the filtration tank 200 to the lower part between the fiber filter medium 220 and the outflow pipe 210 to prevent the suspended matter from being led to the outflow pipe 210. 240 is provided to allow the suspended matter to remain in the filtration tank 200 by the second baffle plate 240.

In addition, when there is no initial rainwater flowing into the inlet pipe 110 of the pretreatment tank 100, the purified initial rainwater of the filtration tank 200 should be drained by using a separate pump to prevent corruption of the initial rainwater received in the filtration tank. In this case, even if the initial excellent water contained in the filtration tank 200 is drained, the initial excellent water contained in the pretreatment tank 100 may not be moved to the filtration tank 200 by the multi-stage baffle 150. Therefore, when there is no inflow of the initial excellent water, the initial excellent water of the pretreatment tank 100 is discharged to the barrier wall 11 separating and separating the pretreatment tank 100 and the filter tank 200 for natural transfer to the filtration tank 200. It is provided with 12 to communicate the pretreatment tank 100 and the filtration tank 200. In this case, the initial superiority of the pretreatment tank 100 has almost no flow of its own, so the upper side has a relatively excellent initial water quality, or the filter 13 is installed on the pretreatment tank 100 side of the outlet 12 to provide the initial superiority. It can be filtered to be introduced into the filtration tank (200).

The discharge port 12 may be installed in the bottom surface of the pretreatment tank 100, the precipitate precipitated in the pretreatment tank 100 may flow into the filtration tank 200, and the pretreatment tank 100 may be installed as the upper surface of the pretreatment tank 100. ), There is a disadvantage in that the amount of initial excellent water remaining in the pretreatment tank 100 increases because the initial excellent water induced in the filtration tank 200 decreases, thus considering the amount of precipitate deposited in the pretreatment tank 100. Can be installed.

The upper part of the filtration tank 200 is further provided with a manhole 270 protruding on the ground in the upper portion of the filtration tank 200 connected to the outlet pipe 210 for the internal management of the filtration tank 200. The manhole 270 may be configured in the same manner as the manhole 170 installed in the pretreatment tank 100, and protects the fiber filter material 220 inside the filtration tank 200, and to prevent a safety accident It is installed to protrude from the surface by the height, the inside of the ladder 271 for entering into the interior of the filter tank 200 and the like can be configured to be provided with a manhole cover 272 at the top. The ladder 271 is configured to reach the bottom of the filtration tank 200, the manhole cover 272 may be provided with a locking device (not shown).

8 and 9 of the accompanying drawings are a cross-sectional view and a plan view showing a processing flow of the initial excellent through the initial excellent treatment apparatus according to the present invention, respectively.

The initial excellent water flows downstream through the rain pipe 20 and is led to the inflow pipe 110 by the overflowware 30 to be introduced into the pretreatment tank 100, and relatively large contaminants are collected in the contaminant collecting network 120. When the initial rainfall of the pretreatment tank 100 increases as the initial rainfall of the pretreatment tank 100 increases or exceeds a predetermined level (a quantity that can be introduced into the multi-stage baffle), the initial rainwater flows into the multi-stage baffle 150. Float and sediment in the multi-stage baffle 150 is gathered to the upper and lower, respectively.

The initial excellent water filtered and suspended in the multi-stage baffle 150 is introduced into the pre-filtration section 201 of the filtration tank 200 and moved to the post-filtration section 202 of the filtration tank 200 by the fine fiber filter material 220 Contaminants are filtered out.

As the initial rainwater introduced from the pretreatment tank 100 increases, the filtration tank 200 is gradually raised in water level, and the initial rainwater filtered through the microcontaminants is discharged to the downstream storm pipe 20 through the outlet pipe 210.

The present invention installs the initial excellent treatment facility at the bottom of the rain pipe or the side of the rain pipe to the same depth as this rain pipe, but reduces the size of the processing device by utilizing the internal shear area, and uses the initial yphon principle. By moving the rainwater, the water treatment can be used to install underground buried material on top of the initial rainwater treatment system. In addition, it can effectively prevent the contamination of river lakes by effectively treating the inclusion of contaminants mixed in the initial rainwater caused by water head difference. have.
