Description

Non-Point Source decrease equipment

The present invention relates to a manhole to reduce the boiling point pollution source by purifying and draining the pollutants in the initial process in which various pollutants accumulated on the road surface or the ground surface is swept away by the rainfall.

In general, roads are provided with a water collecting facility such as a roadside at the edge of the road to drain rainwater generated during rainfall, and the rainwater is collected and then drained to the rainwater treatment facility or river through a drain pipe.

When rainfall occurs, the initial rainwater washes away contaminants from roads and ground and enters the collection facility, which acts as a source of river pollution as well as groundwater. This is called non-point source and facilities are required to reduce such non-point source.

Referring to the conventional non-point source reducing manhole structure, as shown in Figure 1 is partitioned into a partition to form a rectangular box consisting of the first, second tank (1) (2), the first tank (1) An inlet port 4 through which rainwater flows is formed at the upper side, and a water tank dividing wall 3 for dividing the water tank is provided with a overflow port 5 for overflowing the rainwater introduced into the second water tank 2. One side of the two tank (2) is provided with a drain hole (6) when rainwater flows through the inlet (4) is first precipitated various precipitates in the first tank (1) and then through the overflow port (5) After overflowing into the second tank (2), the secondary precipitate is drained through the drain (6). At this time, the second tank (2) is provided with a partition wall 7 which communicates with the lower part, and a filter 8 is installed in the space portion divided by the partition wall 7, and the drain hole 6 is disposed above the filter 8. ) And the rainwater flowing out from the first water tank 1 passes through the filter 8 through the lower portion of the partition wall 7 to filter out various contaminants, and is then drained to the drain hole 6. Particularly, when the rainwater flows in a large amount, the rainwater flowing into the second tank 2 flows directly through the upper part of the partition wall 7 so that the drainage efficiency increases. have.

With this structure, the pollutant is purified in the course of passing through the drainage system and drained to the river or the purification facility, thereby preventing contamination of the river or groundwater due to non-point source pollution.

However, the conventional non-point source reducing manhole does not have a relatively large volume of pollutant removal function included in the initial influent, and only removes pollutants by precipitation and filters. This is due to the fact that most of the decontamination functions are concentrated in the filter, so that the use of the filter will put a heavy load on the filter, which will not be able to perform the decontamination function properly. have.

In addition, the conventional non-point source reducing manhole has a plurality of tanks in order to increase the function of removing the pollutant, which is not only the manufacturing of the tank is difficult due to the characteristics of the concrete material, there is a disadvantage that can not only limit the size of the tank. In addition, even if the tank is manufactured and installed separately, a separate structure for connecting the tank is added as well as a task for connecting the tank in the field has a problem in that a lot of time is required for construction work on the site.

The present invention has been made to solve the conventional problems as described above,

The present invention, in the water tank to install a separate filter network with a structure that precipitates in order to filter the large contaminants contained in the initial influent water to filter out the large volume of the incoming contaminants to the primary contaminants concentrated on the filter By distributing the filtering function, the purpose is to reduce the load concentrated on the filter, to improve the overall pollution source reduction effect, to maintain the filter performance for a long time, and to extend the filter replacement cycle or the filter life.

In addition, the inflow water is vortexed by the filter net so that a relatively large volume of pollutants contained in the water is confined to the center of the vortex formed by the inclination of the filter net, thereby minimizing the clogging caused by the source of contamination. .

In addition, another object of the present invention is to provide a structure that the filter network is installed firmly so that even if the inflow water acts at a high water pressure in the filter network to provide a structure that can withstand a solid and easy disassembly and assembly of the filter network to facilitate maintenance It is.

In addition, another object of the present invention is to provide an easy to manufacture as well as easy to assemble the water tank to be installed in a separate type.

The non-point pollution source reduction manhole according to the present invention for achieving the above object,

A lower body having a plurality of settling grooves on the bottom;

A central body having an inlet through which rainwater is introduced into one upper portion, and having an outlet having a lower gradient than the inlet on the opposite side thereof and laminated on the upper portion of the lower body;

Stacked and assembled on the upper portion of the central body has an opening for access to the upper portion, the upper body is provided with a manhole cover to block the opening on the upper portion; is composed of a separate manganese by the assembly,

The central body is formed between the outlet and the inlet, and the center portion thereof protrudes toward the inlet side, and both ends thereof are separated by both sides by a protruding center portion that forms an inclined wall that is inclined toward both rear side walls. At the same time the bottom is spaced apart from the bottom of the lower body to form a space for water distribution,

Install a filter to filter the pollutant while blocking the outlet side space in the lower portion of the order wall and circulating rainwater from the bottom to the outlet,

A screen having the same shape as the order wall is installed in the space between the bottom and the bottom of the order wall so that the rainwater flowing into the inlet falls and filters foreign substances while passing through the screen.

In addition, the bottom portion is characterized in that a plurality of precipitation grooves are formed to accumulate contaminants to be deposited.

The non-point pollutant source reducing manhole according to the present invention having the structure as described above causes the incoming rainwater to be split into both sides by the order wall, causing vortex, so that the pollutants introduced with rainwater are trapped in the center of the vortex and filtered first, and the screen below the order wall is lowered. Secondary filtering through, and after the third filter by the filter is discharged has the advantage that the efficiency of non-point source reduction is very high.

In addition, the initial inflow rainwater containing a large amount of pollutant is filtered through the screen and filter, and discharges only the rainwater that has been settled and purified, while the inflow rainwater that contains a small amount of contaminants that are subsequently introduced after the pollutant is washed out by the initial inflow water. When the quantity is small, it is discharged after normal filtration process, and when the amount of rainwater is large, it is discharged by overflowing to the upper part of the order wall, so that it has a high purification function and has sufficient drainage capacity.

In addition, the filter is a material that can be easily obtained from the surroundings as the filter medium filled in the filter case is made of yogurt bottle has the advantage of low maintenance costs.

At this time, both ends of the order wall 130 are connected to the side wall surface and the smooth curved surface to be connected. When the upper end of the order wall 130 has a large amount of rainwater flowing through the outlet 120, it has a height enough to be discharged by overflowing, and the lower end is spaced apart from the bottom of the lower body (100c) to distribute the rainwater. Space is provided.

The rear wall of the order wall 130 toward the outlet 120 has a structure in which a vertical wall is blocked by a slab-shaped horizontal wall 131, and a filter installation hole 132 is formed in the horizontal wall 131. The filter 150 is detachably installed.

The filter 150 is composed of a filter case 151 having a lid 153 and a filter member or media 154 embedded therein. The filter case 151 has a plurality of permeable holes 155 formed at the bottom surface, a plurality of permeable holes 155 are formed at the upper lid 153, and a flange 152 is formed at the upper circumference. It is. In addition, the filter member may use a variety of materials that are currently used, the case of the filter medium 154 is composed of the upper and lower penetrated yogurt bottles can be easily obtained from the periphery. Therefore, there is no burden on maintenance and a high filtration function can be expected. The handle is configured to facilitate the attachment and detachment of the filter 150, the lid 153 has a structure that is opened and closed for replacement or cleaning of the filter medium (154).

The upper circumference of the filter 150 is provided with a locking device 163 to prevent the separation by the water pressure of rainwater rising from the bottom. That is, the anchor bolt 161 is installed on the horizontal wall 131 around the upper part of the filter 150, and the locking piece 162 (which may be a washer) is inserted therein, and then the locking nut 163 is fastened. When the lock nut 163 is released, the lock piece 162 is rotated or separated from the anchor bolt 161, so that the filter 150 may also be separated from the filter installation hole 132 of the horizontal wall 131.

On the other hand, a space is formed between the bottom of the lower body (100c) in the lower portion of the order wall 130, the rain can be distributed through this, this is between the bottom of the order wall 130 and the bottom surface of the lower body (100c) Screen 140 is provided to block the space.

In addition, the upper body 100a has an opening 170 formed at an upper portion thereof, and a manhole cover 180 is installed at an upper side of the opening 170 so that an operator can enter and exit the screen 140 or the like. Maintenance such as replacement of the filter 150 is made possible.

It describes the operation of the present invention non-point source reduction manhole made of such a structure.

Rainwater rained down due to rainfall flows to a low place by a gradient, sweeps away various contaminants on the surface such as a road or a sidewalk, and finally flows into the inlet 110 of the manhole of the present invention, which is a drainage facility.

Rainwater introduced with contaminants is filled to the top while falling down to the bottom of the lower body (100c). Rainfall falling in the process hits the central portion 133 of the screen 140 or the order wall 130, the rainwater is naturally split into both sides and guided along the surface of the order wall 130 or the screen 140, and then moved to the side wall surface The 'U' turn on a smooth curved surface leading to the concrete wall surface to move in the reverse direction, and by the rainwater flowing in again, it moves to the order wall 130 or the screen 140 protrusion and eventually the center wall 133 of the order wall 130. At the boundary, both sides have vortices. In this process, contaminants are trapped in the vortex and are particularly efficient at filtering bulky and light foreign bodies.

At the same time, rainwater passes through the screen 140 under the order wall 130, and contaminants are filtered out again.

The rainwater that passes through the screen 140 passes through the filter 150 installed in the horizontal wall 131. The resistance is received while passing through the filter 150, but is more smoothly passed by the water pressure of rainwater that rises in front of the order wall 130. In this process, the pollutant contained in the rainwater by the filter 150 in the filter 150 is filtered by the filter medium 154 filled in the filter 150, that is, the yogurt bottle, and then passes through the upper part of the filter 150 to exit the outlet. Discharged to (120). Along with the above-described series of filtration process, some pollutants included in the rainwater are collected in the precipitation groove 190 at the bottom of the lower body 100c through the precipitation process.

On the other hand, if there is a lot of rainfall inflow of rainwater exceeds the processing limit of the non-point pollution source filter 150 of the present invention rainwater is filled in front of the order wall 130, and eventually overflows the top of the order wall 130, the outlet 120 immediately To be discharged. However, in this case, the rainwater introduced after the initial inflow does not contain the pollutant source or contains only a relatively small amount because the initial inflow rainwater has swept most non-point pollutant sources. Therefore, even if rainwater is discharged by overflowing the order wall 130 without being filtered, it does not harm the non-point source reduction effect at all.

The fixing device 200 forms brackets 210 on both sides of the flange 152 of the filter case 151 and forms the shaft 211 on the brackets 210. At the end, the shaft 220 of the bracket 210 is provided with a handle 220 to form a shaft hole 221 is fitted, the shaft hole 221 is formed a long hole having a length so that the handle 220 is a shaft ( It is possible to slide in the longitudinal direction of the shaft hole 221 in a state where the rotation is free and lying down by 211). In addition, the upper end of the handle 220, the locking ring 230 is fitted to the upper portion of the horizontal wall 131 adjacent to the bracket 210.

When the handle 220 is pushed toward the lock ring 230 in a state in which the handle 220 is horizontally rotated by the structure, the handle 220 is moved within the length limit of the long hole and the shaft (at the end of the long hole) 211) is no longer moved. In this state, the end of the handle 220 is fitted into the lock ring 230, and the opposite end of the handle 220 is in close contact with the upper surface of the lid 153. In such a state, even when high water pressure is applied to the lower part of the filter 150, the handle 220 is firmly fixed to the lock ring 230 so that the filter 220 is never separated from the filter installation hole 132. At the same time, since one end of the handle 220 is in close contact with the upper portion of the lid 153, the lid 153 is not separated from the filter case 151.

On the other hand, when you want to replace the filter medium or filter in the filter case 151 by sliding the handle 220 in the opposite direction and the end is free from the lock ring 230, the filter 150 from the filter installation hole 132 The lid 153 is also freed from the opening of the filter case 151 while being very easy to detach. Moreover, since the handle 220 separated from the lock ring 230 performs a general handle function, the filter 150 may be easily attached or detached.
