Description

Purification of Contaminated Water and Reusing System

The present invention relates to a pollutant purification and water reuse system, and more particularly, to a pollutant purification and water reuse system that can recycle water after environmentally treating rainwater, sewage, and wastewater.

Recently, the amount of pollutant load has increased due to rapid climate change and changes in living patterns, and the pollutants are also diversified. In addition, due to the increase in traffic volume, urban land use patterns, and urban cleanliness, surface runoff during rainfall is increasing rapidly.

Early runoff, in particular, contains relatively high concentrations of pollutants. As the initial stormwater discharged to the river in the untreated state unpurified, water pollution is further increased. Furthermore, stormwater runoff can lead to the accumulation of substances that cause eutrophication of discharged rivers, which can also act as a cause of green algae in summer. Therefore, there is a need for a technology capable of effectively removing nonpoint pollutants generated in various forms in the early stages of rainwater generation.

In addition, recent rainfall patterns have been concentrated in specific periods due to climate change, and there is an urgent need for measures to prevent inundation damage, and the amount of available water is decreasing due to drought frequency and water pollution.

At this time, the shape of the porous absorbent material is formed in the shape of a sphere, an ellipse, or a rectangular parallelepiped.

On the other hand, the hard aggregate 250 is planted in the fine aggregate layer 240.

The treated water storage tank 300 collects and stores the secondary treated water that has passed through the natural vegetation digestion tank. 2, the treatment water storage tank 300 is formed in a storage tank main body 310 in which the secondary treatment water is stored, and an area in contact with the water collecting passage 211, and flows into the storage tank main body 310 as shown in FIG.

The storage tank body 310 is disposed adjacent to the decomposition tank body 210. The overflowware 320 is formed to be connected to the water collecting passage 211. The overflowware 320 shown in FIG. 2 is formed in a rectangular cross section, but may be formed in a triangular shape in some cases. The wearware 320 allows the fine particulate matter (M), which is lost together with the secondary treated water discharged by being filtered through the natural vegetation digestion tank 200, to be separated and sedimented at the bottom. As a result, only the supernatant located above the overflowware 320 is introduced into the storage tank body 310.

At this time, at the distal end of the water collecting passage 211, the outlet opening and closing portion 360 for draining the secondary treated water is provided. 4A and 4B are schematic diagrams illustrating a configuration and an operation process of the spill open / close unit 360.

The bar opening and closing part 360 shown in FIG. 3 is an opening / closing bag 361 and an opening / closing adjustment rod disposed inside the opening / closing bag 361 in which oil is filled in the inside and the volume is elastically changed by the pressure of the secondary treated water. 363, a rotating plate 362 coupled to the inside of the opening and closing bag 361, an oil filling pack 364 filled with oil, and a connecting pipe connecting the opening and closing bag 361 and the oil filling pack 364 to each other.

Opening and closing control rod 363 is one end is fixed to the end of the opening and closing pocket 361 by a fixing pin 362a.

The opening and closing bag 361 is variable in volume by external pressure. The opening and closing pocket 361 is formed of a material having an elastic force, such as rubber and silicon. The opening and closing bag 361 is filled with oil when the water level of the treated water is not high to maintain an oval shape as shown in FIG. 4A. At this time, the water supply hole 363a of the opening and closing adjustment rod 363 is disposed to be offset from the outflow hole (P) so that the treated water is not discharged.

On the other hand, when the water level of the treated water is increased and pressure is applied to the top and bottom of the opening and closing pocket 361, the rotary plate 362 coupled therein is rotated inside by the up and down pressure, whereby the oil filled therein is connected to the connecting pipe ( 365 is introduced into the oil filling pack (364). Therefore, the shape of the opening and closing pocket 361 is reduced as shown in Figure 4b, the opening and closing adjustment rod 363 is pushed to the rear end relatively so that the water supply hole (363a) and the outlet hole (P) is located coaxially do. Therefore, the treated water is discharged out of the overflowware 320 and flows into the storage tank body 310.

Here, the process of restoring the opening and closing bag 361 to the initial state does not occur immediately occurs at intervals of 1 to 2 minutes. To this end, the oil inside the opening and closing pocket 361 is provided with a high viscosity, the connection pipe 365 is formed in a strong form of a small diameter. The density of the oil to be filled is preferably 0.9 kg / cm 3.

The high-density fiber filling tubes 330 and 350 are disposed so that one end is immersed in the treated water inside the treated water storage tank 300, and the other end is exposed to the outside of the treated water storage tank 300. At this time, around the ends of the high-density fiber filling pipe (330, 350) exposed to the outside, the viscous soil is laid and compacted so that the storage water inside the treated water storage tank 300 is continuously discharged naturally. As a result, the treated water stored in the treated water storage tank 300 during the dry season in summer may be recycled into the landscape water.

The top, bottom, left and right of the electrode rods 344, 346 are filled with a fine porous medium (342, 347) and a redox medium (Redox Mediator) or an electron carrier (Electron Shuttle) with excellent concentration of organic pollutants.

Herein, the filling ratio of the microporous media 342 and 347 and the graphite media 343 and 348 is preferably 1: 2. In addition, the particle size of the microporous media 342 and 347 is preferably 5 to 10 mm, and the particle size of the graphite media 343 and 348 is preferably 2 to 5 mm.

In the anode chamber, hydrogen ions (H ⁺ ) generated in the organic material oxidation process of the microorganism are passed through the ion exchange resin to the reduction electrode chamber, and electrons (e +) generated in the above-described process are transferred to the electrode rod 344. It is conducted and moved to the cathode chamber through the conductor. In the present invention, a separate cathode electrode supplying oxygen for the purpose of oxidation of ammonium ions (NH ₄ +) may be selectively applied.

Meanwhile, an ion exchange membrane (345, AMI-7001S, Membranes International Inc., USA) was provided between the anode chamber and the cathode electrode to distinguish the reaction tank. The anode electrode 344 and the cathode electrode 346 mounted in each chamber constituted a circuit by connecting mutual wires.

On the other hand, the following picture is an experimental photograph showing the treatment result over time by the preparation of the reagent based on the general quality of the sewage treatment water to the electrode chamber 340 of the present invention. At this time, 10 / l BOD and 15 / l T-N were selected.

The photograph shows the analysis of the anode electrode 344 and the cathode electrode 346 with a scanning electron microscope (Shiichi, Japan). Shows. In this experiment, no monomeric protein, which is a means for transferring electrons, or a nanowire, which is an enzyme complex that catalyzes a redox reaction, was not found, but the emission electrons were smoothly transferred with high binding force.

The facts that can be derived from the above analysis show that the activity of microorganisms is kept somewhat low due to the extremely low organic load of the treated water, and as a result, the redox potential difference was not large. Through this analysis, it can be seen that the electrode chamber 340 of the present invention removes organic matter and nitrogen by the adherent electron-expressing microorganism even under low load conditions. In addition, it can be confirmed that power generation is possible in the process of removing residual organic matter and nitrogen from the electrode chamber 340.

5 and 6 are a cross-sectional view and a perspective view showing the configuration of the membrane filtration cleaning tank 400 according to the present invention.

The washing tank body 410 is connected by the treatment water storage tank 300 and the inlet pipe 411. The treated water stored in the treated water storage tank 300 is introduced into the washing tank main body 410 by the supply pump 440. The treated water pipe 413 and the contaminant pipe 415 are respectively provided in a direction opposite to the inflow pipe 411. The treated water pipe 413 discharges the treated water which has been processed in the washing tank body 410 to the outside for recycling. The contaminant pipe 415 discharges the contaminants generated after the treatment water from the cleaning tank body 410 to the outside.

The flow meter 417 and the particle size analyzer 419 are respectively disposed on the pipeline of the treated water pipe 413. The flow meter 417 observes the flow rate of the treated water discharged at present. The particle size analyzer 419 analyzes the state of the current treated water.

At this time, it is preferable that the frequency is about 20 kHz to 500 kHz with strong cavitation strength or a high frequency of 1.0 MHz or higher capable of ultra-precise washing due to strong penetration.

Here, the increase in water temperature acts as a factor to decrease the cavitation intensity. Accordingly, the membrane filtration cleaning tank 400 according to the present invention prevents the water temperature rise inside the membrane module 420 by continuously supplying the treated water to the cleaning tank body 410 by the supply pump 440 or the natural inflow. Therefore, the membrane filtration bath 400 may be operated while minimizing the reduction of cavitation strength due to heat.

On the other hand, since the ultrasonic wave is deformed and deformed by the medium, the ultrasonic cleaner 430 is installed at the upper and lower ends of the separation membrane module 420 composed of several layers of hollow fiber membranes. As a result, the front surface of the membrane module 420 is in the area of influence of ultrasonic energy.
