DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a hybrid non-point pollution reduction apparatus using generated power according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

1 and 2, the hybrid non-point pollution reduction apparatus using power generation electric power according to the present invention includes an excellent piping 10, an inflow pipe 20, a power generation chamber 30, a filter medium chamber 40, a discharge pipe 50 , A generator (60), a filter medium (70), and an electric dialyzer (80).

Here, the storm sewer pipe 10, the inflow pipe 20, the power generation chamber 30, the filter medium chamber 40 and the discharge pipe 50 are connected in order to form a continuous flow path, Device. The stormwater that has passed through the abatement system is discharged into the water system or the sewer system.

The power generating chamber 30, the filter medium chamber 40 and the discharge pipe (not shown) of the storm sewer pipe 10, the inflow pipe 20, the power generation chamber 30, the filter media chamber 40 and the discharge pipe 50, 50 are installed in the installation box BX and are moved and installed together with the installation box BX.

The generator 60 is installed in the power generating chamber 30 to generate hydroelectric power by the inflowing vortex and the filter medium 70 is installed in the filter medium chamber 40 to collect the organic material. The electrodialyzer 80 is installed in the discharge pipe 50 to collect the ionic material.

Therefore, the present invention treats non-point pollution in the state of being connected to the storm sewer pipe 10 when the stormwater is introduced in the rainfall, so that it can cope with the inflow of rapid stormwater while reducing the non-point pollution with respect to the stormwater.

Particularly, the present invention is characterized in that the organic material and the ionic material having different physical properties are all purified, the organic material is reduced by the filter medium 70, and the ionic material is converted into electric power by the electric power generated by the hydraulic power, 80).

More specifically, the storm sewer pipe 10 can be applied to the present invention by applying a design change (for example, an inlet pipe connection) to the existing storm sewer pipe 10, Install new piping to enable.

The inflow pipe 20 is connected to the storm sewer pipe 10 as described above, and guides stormwater inflowed from the storm sewer pipe 10 to the treatment place. The excellent treatment place means the location where the filter material 70 and the electrodialyzer 80 described later are installed.

The power generation chamber 30 is connected to the outflow side of the inflow pipe 20 and has a predetermined length to allow the inflow of the storm from the inflow pipe 20 and to install the hydroelectric power generator 60 therein. Therefore, a hydraulic force is generated to cause the generator 60 to run while the storm flows.

Upflow flows into the filter medium chamber 40 as it branches through the upper portion of the power generation chamber 30. [ Such a filter medium chamber 40 may be provided at an intermediate portion with respect to the longitudinal direction of the power generation chamber 30 (the horizontal direction in the figure) as shown.

However, the present invention is not limited to this, but the filter media chamber 40 may be connected to the downstream end of the power generation chamber 30 in the longitudinal direction thereof to move to the end of the power generation chamber 30, As shown in FIG.

The discharge pipe (50) is connected to the water outlet side of the filter material chamber (40). Through the end of this discharge line 50, it is possible to discharge the rain with reduced nonpoint source, but it may also be connected to the water line or the sewer line in such a way as to extend a separate extension line.

The upper discharge side of the filter medium chamber 40 is designed to have a smaller diameter than the lower side inside the filter medium 70 in order to connect the filter medium chamber 40 and the discharge pipe 50. Due to such a structure, the flow velocity at the upper portion of the media chamber 40 is accelerated and the upward flow is accelerated.

At this time, the discharge pipe 50 for the electrodialysis is extended upwardly and then bent in the horizontal direction again to extend for a predetermined length. As shown in FIG. 2, which is a sectional view in the AA 'direction of FIG. 1, do.

Next, the generator 60 is installed in the power generation chamber 30 of the flow path made up of the piping and the chambers as described above, and forms electricity into the power generation chamber 30 and generates electricity by the incoming storm.

The generator 60 includes, for example, a power generation screw 61 and a power generation module 62. At this time, both rotation shafts of the power generation screw 61 are installed on the bracket through bearings, and the power generation module 62 is composed of a stator, a rotor, a coil, and the like as is well known.

Therefore, when the stormwater flows into the power generation chamber 30 to form a vortex, the power generation screw 61 rotates, and the rotor connected to the rotation shaft of the power generation screw 61 rotates to generate electricity.

A filter material (70) is disposed in the filter material chamber (40) and collects the organic material contained in the upward flow. Preferably, the filter medium 70 is made of alginate, which is a biopolymer, to trap and remove organic substances in a nonpoint source.

Alginate is a kind of filter for removing organic substances in aqueous solution. When alginic acid and calcium aqueous solution, which account for 20-30% of algae such as seaweed or kelp, are mixed, they become beeds and collect organic matters.

FIG. 4 is a cross-sectional view taken along the line B-B 'of FIG. 1 showing the filter medium chamber 40 in which the filter medium 70 is mounted. The filter medium 70 is distributed over the entire channel inside the filter medium chamber 40, ). For example, the beads of the filter medium (70) are installed in a honeycomb shape or the like.

The electrodialyzer 80 is installed in the discharge pipe 50 and is operated by receiving electricity generated by the generator 60 to collect ionic substances such as heavy metals. Thus, the present invention removes both organic materials and ionic materials having different physical properties, and is referred to as a 'hybrid' method.

Electrodialysis consists of a pair of cation exchange membranes and anion exchange membranes arranged alternately. In each dialysis membrane, only one of the negative / positive ions passes through and the other does not. Therefore, the ionic substance Capture and remove.

At this time, electricity generated in the above-described generator 60 is supplied to the electrodialyser 80 through the + and - electrodes of the electrodialyser 80. Therefore, the electrodialyzer 80 of the present invention is operated with electric power generated by the storm without receiving power from the outside.

In the present invention, a screen 21 for filtering foreign substances is provided in the inflow pipe 20, and the inflow pipe 20 is connected in a direction orthogonal to the inflow pipe 20, It is preferable that cross-flow is formed.

That is, crossflow is formed by connecting the inflow pipe 20 so that the inflow pipe 20 is arranged in the left and right horizontal direction with respect to the seamless pipe 10 arranged in the vertical direction on the basis of the drawing .

Accordingly, it is possible to prevent the obstacles contained in the rainwater from flowing in at a time to block the screen 21 and to prevent a sudden inflow of rainwater into the inflow pipe 20 to provide a stable flow, Thereby raising the abatement effect.

As shown in FIG. 4, the present invention further includes a bypass pipe 11 connected to the storm sewer pipe 10. The bypass piping 11 is connected in parallel to the storm sewer pipe 10 and has both ends connected to the upstream side and the downstream side of the storm sewer pipe 10, respectively.

Specifically, the inflow side of the bypass piping 11 is connected to the downstream side of the entire length of the storm sewer pipe 10 at a position where the inflow pipe 20 is installed, and the outflow side is connected to the inflow pipe 20 are installed on the upstream side.

The bypass pipe is formed in a substantially 'C' shape to form a circular loop together with the straight pipeline 10, and a backflow prevention device 12 is installed on the upper end of the pipeline.

Therefore, the storm that can not flow into the inflow pipe 20 from the storm sewer pipe 10 or can not flow into the inflow pipe 20 due to the partial occlusion in the treatment device, is discharged through the bypass pipe 11 10 so that the entire amount of the storm can be treated.

Also, as shown in FIG. 4, the present invention preferably includes a plurality of inflow pipes 20 spaced apart along the storm sewer pipe 10. For example, three inlet pipes 20 are connected at regular intervals along the storm sewer pipe 10.

5 is a cross-sectional view taken along the line C-C 'of the generator chamber 30 in the configuration of FIG. 1. As shown in FIG. 5, the generator chamber 30 is connected to each inlet, (60). This is also true of other configurations.

That is, since the power generation chamber 30, the filter medium chamber 40, the discharge pipe 50, the generator 60, the filter medium 70, and the electrodialyzer 80 are provided for each of the plurality of inflow pipes 20, To the stormwater introduced through the inflow pipe (20), and reduces the nonpoint source of rainwater.

Further, when there are a plurality of inflow pipes 20 as described above, a shutter 22 is provided for each inflow pipe 20. The shutter 22 corresponds to the opening and closing of the inflow pipe 20 (for example, a water gate or an on-off valve) and interrupts the flow rate of the inflow into the inflow pipe 20 from the fine pipe 10.

More preferably, the shutter 22 performs an opening operation in which the rain is introduced into the inflow pipe 20 or a closing operation in which the rain is completely blocked. Therefore, when any one of the inflow pipe 20 and the downstream-side processing apparatus is blocked or broken, the shutter 22 is used to close the inflow pipe 20 to enable maintenance.

The vortex generator 90, which is omitted from the above description, is provided at an inlet end (that is, lower open end in the drawing) of the filter media chamber 40 so as to generate turbulence in an upward flow. It consists of a structure including wings.

As shown in FIG. 6, the vortex generator 90 includes an installation frame 91 provided along a rim for coupling to the filter media chamber 40, and a vortex blade 92 fixed to the inside of the installation frame 91 So that a vortex occurs in the storm that has flowed into the filter medium chamber 40 from the upper end of the power generation chamber 30.

Therefore, it is possible to flow the outflow from the inflow pipe 20 to the discharge pipe 50 only by the flow of the self-flowing well without the separate pump, to increase the collision with the filter media 70, So that evenly flows through the filter medium 70.
