Description

Nonpoint-Poient Pollution filtration purification device

The present invention relates to a non-point pollution filtration type purification device, and more particularly, to clean the pollutants before the non-point pollution, which discharges water pollutants by industrial activities in an unspecified area, enters a river or enters an appeal, etc. The present invention relates to a non-point pollution filtration purifier capable of preventing water pollution in advance, as well as protecting aquatic plants of natural ecosystems from nonpoint sources.

In general, nonpoint pollution, as is well known, may refer to a source of discharge of water pollutants unspecifically as a place of a city, road, farmland, mountain, construction site, and the like.

Then, non-point pollution is the main cause of artificial occurrence. ① Active pollution such as tire wear caused by driving on the road. ② Production pollution such as pesticide spraying in rural areas. ③ Construction waste by reconstruction. ④ Excavation work at each construction site. Developmental pollution of ⑤ Non-point pollution occurs for other reasons, such as leachate of household garbage of household.

In particular, the point pollution source, which is one of the causes of unexpected ecosystem destruction due to the rapid development of the industrial society, has more than 90% purification effect with the current technology, but the non-point pollution purification technology is still in the early stage, so it is ineffective in preventing water pollution. Pollution purification technology is emerging as an essential condition.

Conventional technology developed to solve the problem of ecological destruction of non-point source has been discharged into nature after sedimentation by forming a pool in the drainage side of the roadside to temporarily accumulate. It is often seen that the sedimentation basin is buried by soil and loses its function.

In addition, the voids in the filtering network to filter out non-point pollution are inefficient due to the removal of the filtration function due to the closure of soils or lack of post-management. Due to the difficulty of post-management, the voids in the gravel layer were closed, resulting in a new problem of long-term function.

Accordingly, in the present application No. 10-0912708 is filed and registered to improve the rainfall rainfall inlet; 1, 2 stage sedimentation separation; In case of sediment that is pushed down to the initial rainfall by placing the filter infiltration in series, it plays the role of filtering in the 1st and 2nd stage sedimentation, and the remaining harmful water is filtered in the filter infiltration to block the entrance of the soil beforehand. In addition to preventing the collapse of the filter penetrator, it aims to allow the function of the filter penetrant to be semi-permanently operated.

However, the filtration penetrating unit is installed on the ground in order to save the nature as it is, there is a problem that the soil is lost when the heavy rain occurs, when the soil infiltration pipe and outflow pipe is exposed to the outside of the original purpose of non-point source There is a problem that the natural circulation process of the purification system is not realized while being removed by being used as a nutrient source for organic matter to be infiltrated into the filtration layer and used as a nutrient source, or undergoing decomposition by soil microorganisms.

The present invention has been devised to solve the above-mentioned fundamental problems. For this purpose, when the initial rainfall is filled in the primary and secondary sedimentation chambers, the latter rainfall is transferred to the discharge tank along the bypass line and immediately discharged to the outside. The goal is to provide something that can be done.

Another object of the present invention is to install gravel layer, filter sand layer, and underground inlet voids in the filtration penetrating chamber sequentially so that it can be used permanently without collapse even if a concentrated arc occurs, and the non-point source penetrates into the filtration layer and underground after adsorption filtration. It is used as a base flow source by being discharged to the plant, and organic matter is used as a supply nutrient source to plant plants planted at the top, or it can be maintained as the natural circulation process of the purification system proceeds through decomposition by soil microorganisms. It is in providing what it does.

High water level (H) in the primary settling chamber (20) is filled with the inlet of the primary settling chamber (20) having the structure of the lower inclined branched T pipe portion, which is a means to attract the settling chamber (20). Bi-directional basin T pipe 24 consisting of a horizontal straight portion to guide the late rainfall to the discharge tank 50; A bypass line 25 connected to the bidirectional branch T pipe 24 and extending to the discharge tank 50; The soil inlet layer 45 having a plantable plant as an upper layer is stacked in the bottom of the soil layer 45 in the order of the gravel layer 43 and the filtered sand layer 44, but the underground inflow pores 46 allow the purified filtered water to be discharged underground. Filter penetration chamber 40 including; When the rainy season ends, the discharge tank 50 is provided with a discharge hole 50a for lowering the water level of the discharge tank 50 in preparation for the next rainfall.

In the present invention, after the initial rainfall is filled in the first and second settling chamber and the ground layer becomes saturated, the late rainfall is transferred to the discharge tank 50 along the bypass line 25 so that it can be immediately discharged to the outside. The gravel layer, the filter sand layer, and the underground inlet voids are installed in the filtration permeation chamber sequentially so that they can be used permanently without collapse even in case of heavy rains.The non-point source penetrates the filtration layer to remove filtration absorption.

The initial rainfall introduced via the drainage of the roadside, such as the urban surface industrial complex of the city, is introduced into the primary precipitation chamber 20 through the inlet 21. Due to the difference in specific gravity in the primary sedimentation chamber 20, suspended matter and fallen leaves are floated at the low water level (L).

It is precipitated by gravity and collected in the first hopper 22.

In addition, the short-circuit prevention panel 23 disposed in the primary sedimentation chamber 20 blocks the floating material and the fallen leaves, etc., floating in the low water level L into the secondary sedimentation chamber 30.

The non-point pollution treated water filtered by the short circuit prevention panel 23 is moved to the rectifier 32 through the opening 31 and the non-point pollution primary treated water transferred to the rectifier 32 has a rectifier 32 shape. As it is cylindrical, sediment is collected stably in the second hopper 33 by rectifying the fine residual pollutant that is not treated by rectification function of reducing the repair load, and the second non-treatment treated is filtered infiltration chamber (40). The secondary non-point pollution is discharged into the pores 42a formed in the soil penetrating pipe 42 while passing through the soil penetrating pipe 42 embedded therein.

Secondary non-point pollution discharged from the soil penetrating pipe 42 passes through the anthracite layer 44a, the irradiation filtration layer 44b, and the crushed stone layer 44c. Purified effluent is discharged through the lower ground 51 and the surrounding soil is absorbed or absorbed, the purified water infiltrated in the moisture content of the lower ground 51 is unsaturated to supply the base flow by supplying a base flow rate do.

Subsequently, if the base flow is filled according to the continuous rainfall and the water content remains saturated in the underground pore of the lower ground 51, the absorption rate of the purified filtrate is lowered, the penetration rate is lowered, and the water level is started from the underground inlet pore 46. As the final primary sedimentation chamber 20 is filled, the late rainfall is discharged via the bypass line 25.

In the filtration type purifier, the initial rainfall first penetrates through the first settling chamber and the second settling chamber by filtration and penetrating the filtration penetrating chamber 40, and saturates the voids of the unsaturated layer in the lower ground 51 with the filtered water. After the filtration adsorption treatment of the groundwater, and the water content of the lower ground (51) is saturated, the first settling chamber is filled with high water level (H), the late rainfall along the bypass line (25) outlet (50b) As it is discharged into the process, the separation and purification of the initial rainfall is performed smoothly.

After the end of the rainy season, the lower ground 51 is converted into an unsaturated state, and the water level of the primary precipitation chamber, the secondary precipitation chamber, and the filtration osmosis chamber 40 is lowered. At this time, the processing space for natural rainfall is secured. At this time, the water level of the discharge tank 50 is also lowered by the discharge hole 50a of the discharge tank 50.

As described above, when the filtered water is discharged underground, the relationship between the cleaning rate and the expansion rate due to the water temperature change of the filtered water is as follows.

In addition, the efficiency is shown in Table 1 below when the initial rainfall is treated in 5 ~ 10㎥ / hr per hour in 1 to 2 sedimentation chamber and filtration osmosis chamber.

In addition, when the initial rainfall is treated in more than 10㎥ / hr per hour in the 1 ~ 2 precipitation chamber and the filter penetration chamber, the efficiency is shown in Table 2 below.

On the other hand, if the rainfall continues to flow as described above and the water content of the lower ground (51) becomes saturated and the filtration osmosis chamber (40) does not process the contaminated water because the filtration rate is lowered because the treatment rate is delayed primary precipitation chamber It is filled up to the high water level (H) of (20) and the late rainfall is led to the bypass line (25) and discharged to the discharge tank (50).

The discharge hole 50a installed at the lower portion of the discharge tank 50 is purified water penetrated by the filtration permeation chamber 40, so that the water content of the lower ground 51 is filled first, so that the saturated state proceeds. Furnace bypass flow does not occur, and even if bypass is started due to continuous rainfall, the discharge rate does not penetrate into the discharge hole 50a due to the saturated moisture content of the lower ground 51, and the moisture content of the lower ground 51 is unsaturated at the end of the rainy season. When the state has a principle to be discharged slowly.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

In addition, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
