Description

Smart Control Type Non-Point Pollution Reduction Device}

The present invention relates to a non-point pollution reduction device, and more specifically, to a smart control type non-point pollution reduction device that improves management efficiency by allowing the management and control of facilities for the reduction and treatment of non-point pollution substances generated with rainwater to be performed remotely. It's about devices.

Water pollution sources are classified into point pollution sources and non-point pollution sources depending on the nature of the pollution source. Point pollution sources are pollution sources that are discharged in the form of sewers or ditches from points where pollution discharge can be clearly identified, while non-point pollution sources are pollution sources that are discharged from a wide area by rainwater, etc. This means that pollutants are discharged as they are washed and are discharged from scattered pollutants, making it difficult to determine exactly where the emission source is.

In general, non-point pollution sources are also called non-specific pollution sources, surface pollution sources, mobile pollution sources, or other water pollution sources. Unlike point pollution sources that have a specific discharge route, non-point pollutants are generated through unspecified discharge routes such as urban surface drainage or agricultural drainage. It refers to the place or area where it is ordered. Here, the non-point pollutants are mainly pollutants that run off with surface runoff when it rains, such as fertilizers or pesticides sprayed on farmland, soil erosion, livestock runoff, traffic pollutants, dust and waste in urban areas, and natural flora and fauna. It refers to residues, air pollutants that fall on the ground surface, etc.

Recently, it is difficult to confirm the exact outflow path, and management of non-point pollutants generated from roads and parking lots where pollutants inflow is non-continuous is being strengthened. Specifically, dust floating in the air and heavy metals contained in this dust fall and deposit on the road surface, and furthermore, fine particles contained in exhaust gas from driving a car, tire wear caused by driving a car, Environmental pollutants such as asphalt wear and tear are also accumulated. These environmental pollutants contain heavy metals such as cadmium and eutrophic salts such as nitrogen and phosphorus, and can have a detrimental effect on the human body.

In this way, various pollutants accumulated on the road surface are discharged into the river through road drains during rainfall. Although the overall pollutant concentration of the runoff water discharged into the river with rainfall is low, the total amount greatly exceeds that of point pollution sources, so it is stable. To preserve water quality, non-point pollution treatment devices are installed to treat surface drainage from impervious areas such as roads and parking lots.

However, the non-point pollution treatment device in the prior art had a problem in that it was difficult to maintain the facility because the manager had to manually measure the inflow flow rate and manage the operation.

Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the accompanying drawings.

Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This example is provided to more completely explain the present invention to those with average knowledge in the art.

Accordingly, the shapes of components expressed in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same configuration may be indicated by the same reference numeral in each drawing. Additionally, detailed descriptions of the functions and configurations of known technologies that are judged to unnecessarily obscure the gist of the present invention may be omitted.

First, the configuration of a smart control type non-point pollution reduction device according to an embodiment of the present invention is as follows through FIGS. 1 to 6.

The non-point pollution reduction device in this embodiment consists of a concrete structure, a pretreatment tank 10 through which rainwater flows in from the outside through a rainwater inflow pipe 11, and an overflow from the pretreatment tank 10. A filtration tank (20) equipped with a purification filter (23) so that rainwater flows in and filters out contaminants, and a treatment tank (30) in which rainwater flows through the filtration tank (20) and is stored and discharged to the outside. A backwash injection nozzle 25 is configured on the upper part of the purification filter 23 and sprays high-pressure washing water by the operation of the backwash pump 35, and is configured on the lower part of the purification filter 23 and operates the bubble pump 26. a bubble supply unit 24 through which bubbles are supplied, a drain pump 12, 22 configured at the lower part of the pretreatment tank 10 and the filtration tank 20 and performing a drainage operation to adjust the internal water level, and the rainwater inflow. A first filter screen 14 for removing foreign substances formed in the pipe 11, a second filter screen 33 for removing foreign substances in rainwater overflowing from the filtration tank 20 to the treatment tank 30, and A flow sensor 50 configured in the rainwater inflow pipe 11, a water level sensor 13 configured in the pretreatment tank 10, the drain pumps 12 and 22, a bubble pump 26, and a backwash pump ( 35), a control unit 40 that controls the operation and signals of the water level sensor 13 and the flow sensor 50, and a user terminal 60 capable of checking numerical information of the facility through the control unit 40. do.

At this time, the filter blockage state of the purification filter 23 is determined by detecting a change in water level in the water level gauge 13 included in the pretreatment tank 10 and determining that the purification filter 23 is blocked when the water level rises above a certain level above the effective water level. I do it.

In addition, an overflow prevention barrier 21 is formed between the pretreatment tank 10 and the filtration tank 20, and the first filter screen 14 is fixed to the screen fixing wall 21a, and the first filter screen 14 is fixed to the screen fixing wall 21a. A buffer pad 15 made of elastic rubber is provided between the screen 14 and the screen fixing wall 21a to absorb shock generated by incoming rainwater pressure.

In the drawing, unexplained symbols 24a and 25a indicate supply pipes through which bubbles and washing water are supplied, respectively.

Let us look at the effects of the operation of the smart control type non-point pollution reduction device of the present invention configured as described above.

The initial rainwater flows in through the rainwater inflow pipe (11) of the pretreatment tank (10) and is stored at a certain level, and the rainwater that overflows the overflow barrier (21) from the pretreatment tank (10) is transferred to the filtration tank (20). It gets moved.

At this time, the flow rate of rainwater flowing in through the rainwater inflow pipe 11 is detected by the flow sensor 50, and the water level inside the pretreatment tank 10 is detected by the water level gauge 13 and is monitored by the control unit 40 in real time. The transfer takes place through .

In addition, rainwater flowing into the rainwater inflow pipe 11 collects impurities such as fallen leaves while passing through the first filter screen 14 with a plurality of through holes 14a. The impurities collected in this way can be easily discharged to the outside through the upper manhole cover using a basket (not shown).

Thereafter, in the filtration tank 20, fine pollutants mixed in rainwater are captured as they pass through the purification filter 23 and move upward.

Rainwater that has been purified by passing through the purification filter 23 in this way overflows into the treatment tank 30 and is then discharged into an external drainage facility or river through the discharge pipe 31 formed on one side of the treatment tank 30. It will come true.

At this time, in the process of overflowing into the treatment tank 30, the remaining fine foreign matter passes through the second filter screen 33 and is screened.

Meanwhile, the water level gauge 13 installed in the pretreatment tank 10 detects changes in water level, and when the water level is 10 cm higher than the effective water level, it is determined that the purification filter 23 is blocked and cannot function again, so filter cleaning can be performed. , the drain pump 22 is operated by a control signal from the control unit 40 to lower the water level in the filtration tank 20 by the height of the purification filter 23, and the bubble supply unit 24 and the backwash injection nozzle 25 are operated. Filter cleaning takes place.

That is, when bubbles are generated from the bubble supply unit 24, the generated bubbles flow into the purification filter 63, separate foreign substances adhering to the pores in the filter, and are discharged to the top.

At the same time, when the backwash pump 35 operates and high-pressure wash water is sprayed through the backwash spray nozzle 25, the high-pressure wash water is sprayed onto the upper surface of the purification filter 23, thereby separating foreign substances adhering to the surface. Clogging and contamination of the pores of the purification filter 23 can be prevented.

In particular, in the present invention, it can be seen that the manager can automatically control the control unit 40 according to remote access using the manager terminal 60, thereby improving management efficiency due to the introduction of IoT technology.

Therefore, the smart control type non-point pollution reduction device of the present invention allows the management and operation control of the non-point pollution reduction facility to be performed remotely through the manager's smartphone or terminal, thereby enabling more efficient facility management.

In addition, smart control technology that combines screen-type non-point pollution reduction facilities and device-type non-point pollution reduction facilities is applied, enabling safe monitoring through short- and long-distance communication without access to existing facilities.

Meanwhile, Figures 5 and 6 show a configuration according to another embodiment of the present invention. Inside the first filter screen 14, there is a distribution plate for uniform distribution of rainwater flowing in through the rainwater inflow pipe 11. (16) is configured to form an inclined surface at a certain angle, and a guide wire mesh (17) is extended to the lower part of the distribution plate (16) to provide support by connecting to the bottom surface of the first filter screen (14), and to provide distribution. The plate 16 has a magnet 18 for magnetic force in the shape of a cone or pyramid, and an elastic spring 19 for elastically supporting the magnet 18 is located at the bottom.

In addition, a buffer surface (16a) is coated on the surface of the distribution plate (16) to reduce noise from rainwater and prevent contamination, and the buffer surface (16a) is made of 5 to 20% by weight of polytetrafluoroethylene and polysulfone. Resin 10-30% by weight, methyl fluoride 1-10% by weight, urethane powder 10-20% by weight, phenylalanine tetrahydroxylase 1-15% by weight, chromium oxide 1-10% by weight, sodium hexanitrocobaltate 5~ It is preferable to form a mixed composition in a ratio of 15% by weight, 1 to 10% by weight of silica sand, 1 to 10% by weight of calcium carbonate, and 1 to 10% by weight of potash feldspar.

When this configuration is achieved, rainwater flowing in through the rainwater inflow pipe 11 is guided along the slope of the distribution plate 16, thereby reducing the impact and noise of falling water. At this time, initial foreign matter removal and buffering action are performed by the guide wire mesh 17 and the elastic spring 19, and fine metal foreign matter can be collected by the magnet 18.

In addition, since the distribution plate 16 is coated with a buffer surface 16a, the effect of reducing noise from falling water can be maximized.

In particular, since the coating composition forming the buffer surface 16a contains a mixture of polytetrafluoroethylene components, deterioration and discoloration of the polysulfone resin are prevented, and methyl fluoride and phenylalanine tetrahydroxylase increase the bonding strength between the mixtures. It has the function of improving the durability of the coating layer, and chromium oxide and sodium hexanitrocobaltate can improve surface lubricity. In addition, the additionally added silica sand and calcium carbonate suppress the generation of bubbles on the buffer surface 16a during the coating process, and the potash feldspar exhibits an advanced effect of improving coating density.

In addition, although specific embodiments of the present invention have been described and shown above, it is obvious that the structure of the non-point pollution reduction device of the present invention can be implemented in various modifications by those skilled in the art.

Therefore, such modified embodiments should not be understood individually from the technical spirit or scope of the present invention, and such modified embodiments should be included within the scope of the appended claims of the present invention.
