The present invention relates to a wastewater on-site recycling sprinkling system.

In Korea, the concentration of dust in the air is very high due to the drier climate and the exhaust of automobiles. Especially in the spring, when the dry season lasts quite a long time and even yellow dust from China overlaps, it is necessary to refrain from going out. According to a recent press release, fine dust concentrations in Seoul and other cities are among the highest among OECD countries.

These fine dusts float in the air and then slowly sink and accumulate intensively on the roadside along with other pollutants, and then float back into the air as the air flow moves to increase the concentration of atmospheric dust.

Road cleaning using roadside water cleaning vehicles is one of several methods performed to reduce the amount of dust described above. The water cleaning vehicle runs around a road or a construction site with a lot of traffic, and sprays water on a road surface to wash dust and the like.

However, the cleaning of the road surface using the cleaning vehicle has a limitation in that its efficiency is very low compared to the investment and cost. For example, it is not difficult to remove sand, soil, or rubbish from the roadside, but it is practically impossible to remove fine dust having a diameter of 2.5 micrometers or less. The fine dust does not have a high quantitative proportion of the total pollutants, but has a very bad effect on human health.

Furthermore, road cleaning using a cleaning vehicle is performed while driving along a roadside where dust contaminants are concentrated. For example, when a vehicle is parked on the roadside during a cleaning time, cleaning of the corresponding place is impossible. Even if the cleaning is completed except for the parked place, the unremoved dust in the place where the vehicle is parked is easily blown away and very easily pollutes the cleaned place.

In addition, the cleaning operation using the cleaning vehicle is mainly performed at dawn so that the cleaning vehicle does not interfere with the traffic flow of other vehicles. This means that cleaning is not possible during the day or in the afternoon, when traffic is increasing in earnest and dust concentrations peak.

On the other hand, most of the water currently used for road cleaning is groundwater or river water generated from subway stations. The groundwater or river water is used for road cleaning and then penetrates underground or flows to sewage treatment facilities through sewer pipes. However, the use of the groundwater or river water to meet the demand has a problem that can reduce the water resources of the city. In order to increase the fine dust reduction efficiency and to clean a wider road surface, a larger amount of water is required, but river water or groundwater cannot be used in abundance as mentioned above.

The present invention has been created to solve the above problems, it is installed on the road surface, the concentration of dust in the air increases or when dry or other needs, by spraying the cleaning water on the road surface can greatly reduce the pollution by the dust of the area. In addition, it is possible to prevent heat island phenomena heated by asphalt and concrete during the summer, and to recycle the mixed wastewater that is discarded in the building anyway and to enrich the soil moisture content. It helps to reduce the amount of sewage generated by recycling the wastewater that was sent to the sewage treatment plant along with the wastewater, and at the same time, it can increase the treatment efficiency of the sewage treatment plant by collecting high concentrations of wastewater to the sewage treatment plant. Restroom or other heavy water in the building The purpose of the present invention is to provide a recycling system for on-site water drainage, which can save water resources, because it can be sent to demand.

The present invention has been created to solve the above problems, and a multiplying water storage tank for temporarily storing the multiplying water discharged from the building; A miscellaneous wastewater treatment unit which takes over the miscellaneous wastewater stored in the miscellaneous wastewater storage tank and purifies the wastewater into heavy water; It is characterized in that it comprises a sprinkling means connected to the wastewater treatment unit and installed on the road surface and spouting heavy water provided from the waste water treatment unit to the upper portion of the road surface.

In addition, the watering means is installed lower than the road surface is characterized in that it comprises a sprinkler for cleaning the road surface by spraying the supplied heavy water to the top of the road surface.

In addition, the sprinkler is characterized in that it can be installed in close proximity to the road so that the heavy water can be used as landscape water.

In addition, the heavy water supply unit; It is characterized in that it further comprises a heavy water storage tank for receiving and temporarily storing the heavy water processed by the job drainage treatment unit, and a heavy water supply pipe connected to the heavy water storage tank and supplying the heavy water of the heavy water storage tank to the heavy water use place in the building.

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

The water used in ordinary households is usually used at a rate of 30% for toilet water, 31% for bath or shower, 20% for washing or dishwashing, 6% for drinking or cooking, and 5% for brushing and other water. It is estimated. Of course, there will be differences depending on the case, the present invention is also based on the view that can be recycled by simple treatment on the site more than 50% of the water except the toilet water.

1 is a view for explaining the overall configuration and operation mechanism of the waste water recycling site water sprinkling system according to an embodiment of the present invention.

Referring to the drawings, the watering system according to the present embodiment, the job water storage tank 30 through the job water storage tank 30 and the job water transfer pipe 32 for temporarily collecting and storing the job water generated from the job drainage source 26 in the building 10 A job drainage treatment unit 36 that receives the job drainage stored in the water 30 and handles the job drainage as heavy water, a heavy water storage tank 38 for temporarily storing the heavy water treated by the job drainage processing unit 36, and the heavy water storage tank 38 Pump 40 to send the heavy water stored in the heavy water supply pipe 42, and is installed in communication with the heavy water supply pipe 42 and installed in the lower portion of the road surface (A) a plurality of spraying heavy water to the upper road surface if necessary Sprinkler 50, a heavy water storage tank 54 for temporarily storing heavy water through the heavy water supply pipe 42, and a heavy water supply pipe connecting the heavy water storage tank 54 and the heavy water use place 62 in the building (A) 58).

First, the waste water generation source 26 includes, for example, a washroom or shower or a bathroom, a laundry room, or a kitchen. In addition, unlike the wastewater generated in the toilet as the water generated at the wastewater generation point 26, the wastewater is water that can be used as toilet water, washing water, or landscape water only through simple filtration, sedimentation, disinfection, and the like.

In any case, the wastewater generation source 26 is supplied from the outside and discharged through the wastewater discharge pipe 28 after using the constant water supplied through the constant inlet 20, the constant supply pipe 22, and the water tank 24. do. Reference numeral 21 is a pump for supplying the water inside the water inlet 20 to the water tank 24 on the roof of the building.

The wastewater discharged through the wastewater discharge pipe 28 reaches the wastewater storage tank 30 provided in the basement of the building A and is temporarily stored. The mixed waste water storage tank 30 may be a plurality of storage tanks configured in series or in parallel or one storage tank. In addition, the waste water storage tank 30 may be installed one unit in one building, or may cover several buildings simultaneously with one unit. In other words, one miscellaneous water storage tank 30 may be configured to receive and store miscellaneous water in multiple buildings.

The wastewater collected in the wastewater storage tank 30 is moved to the wastewater treatment unit 36 by the pump 34 via the wastewater transport pipe 32. The mixed wastewater treatment unit 36 gradually passes the transferred mixed wastewater and changes it into heavy water through a process such as precipitation, filtration, and disinfection.

The precipitation, filtration, and disinfection are in accordance with a general water purification process capable of simply treating the wastewater in the field, and the composition can be changed as long as the wastewater can be treated with heavy water.

The sedimentation process is a process of precipitating heavy material inside the wastewater obtained through the water transfer pipe 32, and the filtration process is a process of filtering and removing suspended substances in water, and the disinfection process is a germ in water using an antiseptic solution. By disinfecting mold and mold, heavy water can be safely used as toilet water, washing water or landscaping water.

In any case, the multiple wastewater treatment unit 36 may be installed in plural according to the discharge of the mixed wastewater from the building (A) or according to the conditions of the region. In addition, the wastewater treatment unit 36 may be installed in a basement or other underground space of a building.

The heavy water processed by the miscellaneous wastewater treatment unit 36 is temporarily stored in the heavy water storage tank 38. Reference numeral 52 is a control unit. The controller 52 controls the pumps 21, 34, 40, 56, various valves, and the like, and is operated by the manager.

The heavy water stored in the heavy water storage tank 38 is pumped by the pump 40 and sent to the water spraying unit 48 or the heavy water storage tank 54.

The watering unit 48 includes a plurality of sprinkler 50 installed on the road surface (A). The sprinkler 50 is to spray the heavy water supplied through the heavy water supply pipe 42 and the branch pipe 46 to the upper road surface. The type of the sprinkler 50 may be any type as long as the heavy water can be injected upward.

The heavy water sprayed upward by the sprinkler 50 can clean various contaminants accumulated on the road surface and remove fine dust floating below a certain height (maximum reached height of the heavy water sprayed upward). Can be.

The principle that the flotation fine dust is removed by the heavy water sprayed as described above is the same as the principle that the dust of the atmosphere is washed away by rainwater during rainfall. In addition, the contaminants accumulated on the road surface flow through the heavy water flowing along the road surface, for example, to be removed through the roadside drain (68 in FIG. 2).

In particular, when the entire surface is wetted using the sprinkler 50, the ambient temperature is dropped by the evaporative heat of heavy water generated from the road surface, and thus, it is possible to effectively prevent heat island phenomenon occurring especially in the summer, and use indoor or vehicle air conditioners. It can also save energy.

The sprinkler part 48 including the sprinkler 50 should be installed in advance under the road surface A during the road construction. In addition, the road surface (A) is provided with an opening (B) for opening the sprinkler 50 to the top. The type of the opening (B) may be configured differently depending on the case.

The sprinkler 50 is located inside the opening (B), but the upper end is located below the road surface (A) so as not to be stepped on the tire of the car passing through the road. In addition, by installing a separate support member (not shown) below the edge of the opening (B), it is good to reinforce the sprinkler 50 so as not to dent.

Usually, when the sprinkler 50 is installed on the roadway paved with asphalt or concrete, it is preferable to locate the center line (C of FIG. 2). In addition, in the case of roads with roadside trees (D in FIG. 3), sprinkler 50 may be installed in the soil around the roadside trees to use heavy water as landscape water and road washing water.

Meanwhile, when the watering unit 48 is not operated or when the amount of heavy water consumed by the watering unit 48 is small, the remaining heavy water moves to the heavy water storage tank 54 along the heavy water supply pipe 42 and is temporarily stored.

The heavy water stored in the heavy water storage tank 54 is supplied to the heavy water use place 62 in the building via the heavy water supply pipe 58 and the heavy water tank 60 by the pump 56. The heavy water use place 62 may be a toilet as a place where there is no problem even using heavy water in a building. Conventionally, the constant water is used as the toilet water, but as described above, heavy water is used as the toilet water, thereby saving the water resource.

The water used in the heavy water use place 62 is collected in the wastewater storage tank 66 through the wastewater discharge pipe 64 as wastewater and then sent to the end treatment plant.

Figure 2 is a perspective view showing an installation example of the sprinkler in the watering system shown in FIG.

Referring to the drawings, it can be seen that a plurality of openings (B) are provided on the central line (C) painted in the center of the road surface (A) of the road, and the sprinkler 50 is installed in the opening (B). have. Heavy water ejected from the sprinkler 50 soaks the road surface and removes the dirt accumulated on the road surface as well as fine dust floating near the road surface.

Heavy water spouted from the sprinkler 50 flows to the outer portion of the road surface A along with contaminants such as dust, is absorbed into the soil S through the drain hole 68, or flows through the sewage pipe to the sewage treatment plant. In addition, the water cleaning the road as described above moves to the soil (S) it is possible to increase the water content of the soil.

3 is a diagram showing another installation example of the sprinkler in the watering system shown in FIG.

Referring to the drawings, it can be seen that the roadside tree D is planted in the middle of the road surface A, and the sprinkler 50 is installed around the roadside tree D. The sprinkler 50 injects the heavy water pumped through the heavy water supply pipe 42 to the roadside (D) and the road surface (A).

The heavy water sprayed to the road surface A side cleans the road surface and the heavy water supplied to the roadside tree D is supplied as water for landscape water D and the soil around the roadside tree to increase the water content of the soil. Conventionally, when there is no rain, the constant sprinkler is operated to supply water to the roadside, but when the present invention is applied, it is not necessary to use the constant sprinkler.

As a result, the present invention made as described above, it is possible to greatly save the water resources by collecting the waste water that was conventionally thrown away with the waste water, and simply treated in the field and recycled into heavy water. In addition, the sprinkler is installed on the road surface and the heavy water is ejected through the sprinkler so that the road surface can be cleaned whenever necessary without the addition of equipment or the traffic flow, so that the cleaning efficiency is very high and various problems caused by fine dust can be solved. Lowering the temperature also helps prevent heat islands.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.

The mixed wastewater on-site recycling and sprinkling system of the present invention as described above is installed on a road road surface to increase the concentration of dust in the air or when dry or other occasions, by spraying cleaning water on the road surface from time to time to prevent contamination by dust in the area. It can greatly reduce and further prevent the heat island phenomenon that is heated by asphalt and concrete in summer.In particular, it uses heavy water treatment to recycle the wastewater that is thrown away from the building and enriches the soil's moisture content, not using groundwater or river water. It helps to grow roadside landscaping water and plants, and reduces the amount of sewage generated by recycling wastewater that has been sent to the sewage treatment plant along with the wastewater, and at the same time, it sends sewage treatment plants of high concentration to the sewage treatment plant to increase the treatment efficiency of the sewage treatment plant. Can and also rehabilitation Collected heavy water can be collected and sent to heavy water demand where toilets and other heavy water can be used in the building, thus saving water resources. Therefore, it is effective to cope with the water shortage in large cities with high water demand during the dry season. To be able.
