Description

[0001] The present invention relates to a water-soluble bad smell removal device with effective microorganisms,

The present invention relates to a malodor reduction apparatus, and more particularly, to a water-soluble malodor reduction apparatus using an effective microorganism capable of effectively reducing the water-soluble odor of wastewater.

Since the mid-1980s, a variety of biological treatment techniques have been undertaken in Europe, including volatile organic compounds (VOCs) and odors emitted in the atmosphere. Since the 1990s, VOCs and odors have been removed from contaminated air Technology has become a major problem in the air pollution sector. Biofiltration purifies polluted air by means of a mechanism that fills the inside of the reactor with a packing with a microbial membrane and allows polluted air to pass through the packing material so that the pollutant diffuses into the microbial membrane, Technology.

The biological removal method is more economical and has a wider application range because it is cheaper than the physicochemical treatment technology such as the conventional incineration method and the activated carbon adsorption method for treating VOCs, and is very useful technology for purifying polluted air generated at a large capacity and low concentration .

Historically, as early biofilters used since the 1960s, soil beds have been used in which contaminated air is injected into the soil bed and removed by soil adsorption and soil microbes. This method is effective in eliminating VOCs and odors by more than 90%, but the soil image requires a large site and there is a technical problem of supplying high pressure loss and uniform air inside the soil layer.

Since the 1980s, organic materials such as compost, peat, wood bark, etc. have been mainly used for the treatment of odor and VOCs as a filler of biofilters. However, these organic fillers have a high removal efficiency due to high physical adsorption and good moisture retention, but the disadvantage is that the microbes decompose the filler itself and are consolidated by means of the mineralization to keep the air flow constantly to the filler layer.

Because of these disadvantages, the organic filler should be replaced or relocated about once a year to maintain the treatment efficiency. Recently, attempts have been made to improve the efficiency of biofilters by mixing organic materials such as compost, pit, etc. with inorganic materials such as plastic, pellet type activated carbon, and ceramics in order to overcome the disadvantages of such organic fillers.

When VOCs are treated with a conventional biofilter using organic materials as a filler, the microorganisms are decomposed and used as a carbon source to decompose the VOCs. Therefore, when the microorganisms adhere to the filler and grow excessively, excess microorganisms (biomass) The pressure loss is caused, thereby reducing the processing air volume and lowering the treatment efficiency, thereby lowering the overall removal efficiency. In the trickling air biofilter, too much pressure loss is caused by the excessive growth of surplus microorganisms. In order to solve these problems, US Soriel et al. (1997) designed a method of inhibiting the growth of microorganisms by using NaCl, but eventually the growth of microorganisms was obstructed and the treatment efficiency was drastically reduced.

In addition, in the case of sulfurous substances such as hydrogen sulfide, sulfur sulfide, methyl sulfide, methyl mercaptan, etc., and inorganic nitrogenous substances such as ammonia, clogging due to excessive microbial growth is not a serious problem, Maintaining one microbial concentration is one of the most effective ways to increase efficiency.

In the case of a residential area located near the industrial complex area, many odors are dispersed due to contaminated air and wastewater discharged from factories, which is a great obstacle and difficulty in life. At present, at the industrial level, the pollutants that are polluted by external pollutants are blocked by using a purifying filter, but they do not frequently replace the consumable filters of solid type. In the case of the residents, there is no measure against air pollution.

Therefore, there is an urgent need for an apparatus capable of reducing the water soluble odor in the contaminated air discharged around the industrial complex and the waste water treatment apparatus by utilizing the environmentally friendly effective microorganisms at low cost in daily life.

Among polluted air and odor generated in industry, water-soluble gas which is soluble in water is also included. Representative gases include nitrogen-based ammonia (NH ₃ ) and carbon dioxide (CO ₂ ) as volatile odor gases. Double oxidized carbon is odorless in itself, but it may cause odor if it causes chemical change.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a constitution of a water-soluble odor reduction apparatus using an effective microorganism according to an embodiment of the present invention; FIG. Fig. 1 (a) shows a front view and Fig. 1 (b) shows a side view. FIG. 2 is a view showing the shapes of the inlet plate 250 and the baffle 310 used in the embodiment of the present invention. FIG. 3 is a view showing the structure of the cylinder filter portion used in the embodiment of the present invention, Is a perspective view illustrating an overall configuration of a water-soluble odor reduction apparatus using an effective microorganism according to an embodiment of the present invention.

As shown in FIG. 1 and FIG. 4, the water-soluble odor reduction apparatus using an effective microorganism according to an embodiment of the present invention includes a box-shaped housing 100 filled with an effective microbial culture solution; An air inflow part 200 positioned at the lowest end of the inside of the housing 100 to introduce polluted air; A polluted air purifying part 300 having a plurality of porous baffles 310 spaced apart from each other at an upper end of the air inflow part 200; A cylinder filter unit 400 formed at the upper end of the polluted air purifying unit 300 and formed of a multi-stage disk 410 for attaching or sucking impurities formed by dissolving the polluted air; And a discharge unit 500 for discharging air generated at the upper end of the box-shaped housing 100 to the outside.

As described above, according to the present invention, after the effective microbial solution is filled in the box-shaped housing 100, contaminated air generated in an industrial site or various polluted air discharge areas flows through the air inlet part 200 at the lower end, The water soluble odor gas such as volatile gas rises and flows through the polluted air purifying unit 300 and the cylinder filter unit 400 and is purified by the biological purifying action and then purified through the uppermost discharging unit 500 Or a gas is discharged.

The embodiment of the present invention is different from a simple biofilter through a conventional photocatalyst or the like and is sufficiently spaced apart in the vertical direction in accordance with the rising of the polluted air so that the polluted air sufficiently contacts with the effective microorganism solution to promote microbial culture and purification action And the water-soluble odor air is dissolved by the cylindrical cylinder filter portion 400 in which the plurality of disks 410 are rotated at the upper end of the housing 100, A secondary filter function that filters out byproducts or various impurities is provided to provide a more efficient odor air cleaning apparatus.

Further, unlike the conventional biofilter using an organic material as a filler, the embodiment of the present invention does not cause problems of uneven distribution of effective microorganisms, pressure loss and efficiency reduction due to excessive production of microorganisms, The present invention provides an apparatus capable of inducing a uniform and uniform flow of a mixed fluid to improve the purification efficiency.

As shown in FIG. 2, the air inlet 200 corresponds to the external contaminated air inlet 200 formed at the lower end of the box-shaped housing 100, And an underwater pump 210 connected to the inlet port is installed inside the lower end of the housing 100 to effectively introduce the polluted air.

The box-shaped housing 100 is filled with an effective microorganism solution for biological air purification. The air introduced from the air inlet portion 200 forms bubbles or the like, and moves to the upper end of the effective microbial solution due to the specific gravity of the bubbles . In this process, the contaminated air is dissolved in the water-soluble gas and the effective microbial solution in the contaminated air, or the microbes existing in the effective microbial solution decompose some gas substances.

The air inflow part 200 has a possibility that the contaminated air from the outside flows quickly due to the driving of the submersible pump and the flow of the air moves to one side. Therefore, in order to disperse and uniformly distribute the air, An inflow plate 250 having a plurality of through holes is provided between the contaminated air purifying part 300 and the air inflow part 200.

The inflow plate 250 performs a cover function of the air inflow part 200, and at the same time, the inflow plate 250 uniformly distributes to the air inflow part 200 and serves as a path for uniformly moving the contaminated air, A large number of through holes are formed in the plate to secure a polluted air transfer passage and to induce uniform distribution of diffusion to the upper portion, thereby enabling efficient gas-liquid contact in a large area, thereby improving purification efficiency.

A contaminated air purifying unit 300 is installed at the upper end of the air inflow unit 200 for securing a space and prolonging a gas-liquid contact time so as to purify contaminated air through the effective microbial solution The polluted air purifying part 300 is formed in a structure in which a plurality of porous baffles are attached in parallel on both sides of the housing 100 in the vertical direction at regular intervals.

The present invention proposes a structure in which the porous baffles 310 are spaced apart from each other at regular intervals in the vertical direction by passing through the inflow plate 250 from the air inflow part 200 at the lower end of the housing 100 The bubbles of the contaminated air that has risen rapidly move to the upper end. Since such a rapid movement has a problem that the reaction or contact time with the effective microbial solution is shortened and the purification efficiency is lowered, If the porous baffles 310 are arranged at regular intervals and are arranged in a vertical direction, the movement of the polluted air is delayed to increase the gas-liquid contact time, and the baffle 310 distributes and spreads the polluted air evenly due to the through- This is because the contact area can be widened to increase the efficiency of microorganisms or chemical reactions.

Such a plurality of baffles 310 may be installed such that the entire cross-section of the housing 100 is installed as a partition wall through the lower inlet plate 250 so that contaminated air can pass through the through holes. As shown in FIG. 1, The baffle 310 is mounted on one side of the housing 100 while the sectional area of the baffle 310 is smaller than the sectional area of the housing 100 and the baffle 310 is mounted on the opposite side of the housing 100 The baffles 310 are mounted in a zigzag fashion at regular intervals to make the air flow more smooth.

Figure 2 illustrates the shape of the inlet plate 250 and the porous baffle 310 applied to an embodiment of the present invention. As shown in FIG. 2, the inlet plate 250 and the porous baffle 310 have a structure in which a plurality of through holes are formed in a plate having a predetermined area, and the contaminated air rising through the through holes is guided to be smoothly and uniformly distributed do. Since the material of the inlet plate 250 and the baffle 310 is easily corroded by the acidic solution generated by reacting the odor-contaminated air with the effective microbial solution, it is preferable to use a non-metal material such as plastic, glass, or polymer Do.

As described above, in the related art, the polluted air bubbles rapidly rise, and the time for gas-liquid contact with the effective microbial solution can not be sufficiently secured, thereby decreasing the purification efficiency. In the present invention, It is possible to delay the flow of the polluted air bubbles by the plurality of porous baffles 310 installed in the unit 300 and to increase the efficiency of the purifying action by increasing the gas-liquid contact time.

As shown in FIGS. 1 and 3, a cylinder-shaped cylinder filter unit 400 composed of a multi-stage disk 410 is installed at the upper end of the polluted air purifying unit 300. After the process of sufficiently reacting with the effective microbial solution in the polluted air purifying part 300, the filter part of the culled filter purifies the byproducts or impurities which are dissolved in the water soluble odor air or can not sufficiently react with the microbes, The present invention also provides an apparatus for performing a secondary filtering process for facilitating the operation of the apparatus.

The cylinder filter unit includes a rotating rod 450 formed in a horizontal direction at an upper end of the housing 100 and a rotating rod 450 fixed to a center axis of the rotating rod 450, A plurality of circular disks 410 spaced apart at regular intervals and a motor connected to the rotary rods 450 and installed outside the housing 100 to rotate the rotary rods 450 Do.

That is, the cylinder filter 400 includes a rotary rod 450, a multi-stage disk 410, and a rotary motor. The rotary rod 450 includes a rod- And a plurality of circular disks 410 are mounted on the rotary rod 450 at predetermined intervals in the longitudinal direction around the rotary rod 450. The rotary rods 450 By rotating the rotary rod 450 by connecting a rotary motor to one side, the filtration process is performed by attaching various by-products more efficiently in the dissolving process of the water soluble odor.

The cylinder filter rotating structure smoothly moves the fluid of the polluted air purifying part 300 upward and rotates at a rotating speed of about 5 RPM or less to naturally attach the dispersion to the multistage disk 410 This is because the by-products and chemical bonds dissolved in the effective microbial solution tend to adhere to the surface of the cylindrical disk 410 having a large surface area. This enables the effective microorganisms to oxidize and decompose the organic substances attached to the surface of the plurality of disks 410 to perform the secondary purification function of the solution.

The discharge unit 500 forms a discharge port at the upper end of the housing and serves as a passage for discharging the purified polluted air formed in the water level upper space filled with the effective microorganism solution inside the housing to the outside. The discharge portion 500 may be provided with a mesh filter for physically removing impurities of general dust, so that cleaner and purified air can be discharged to the outside. It is also possible to mount the suction air pump in the discharge portion 500 to efficiently discharge the purified polluted air generated at the upper end of the cylinder filter portion.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with it will know easily.
