Deodorizing device

This creation is about deodorizing devices. In more detail, this creation is about a deodorizing device that does not adversely affect the environment and the human body, and can perform amazing deodorization from deodorant.

The stench of the sewage treatment plant, the garbage incineration plant, the composting plant, and the manure disposal site is not only deteriorating the working environment on the site, but also threatening to deteriorate the living environment of the residents around the country. However, it is almost impossible to deodorize the above-mentioned odors to the extent that people are unaware or have little feeling of discomfort.

Further, in the sewage treatment plant, the treated water is treated by the activated sludge process. In such a system, in general, microorganisms such as Bacillus subtilis are dominant groups. However, sludge treatment that occurs in such prior treatment systems is a difficult problem. Sludge is the root cause of odor and pollution, and the cost of treatment is high. In addition, when considering environmental problems, the abandoned waste sludge is naturally limited. In the near future, even local governments may not It is possible to ensure the waste of the sludge.

The author, etc., after repeated research, found that a certain microbial group can perform amazing deodorization and sludge decomposition effects, and can complete the creation. Such as a deodorant, which will contain heat-resistant actinomycetes, green pus Microorganisms of bacteria, C. mobilis, Sphingomonas, Acinetobacter, Nitrosomonas, and Nitrobacter are active ingredients. A deodorant as described above is a shape in which a microorganism group is dispersed in water. The deodorant as described above is a zeolite-microbial complex obtained by contacting zeolite and a microorganism group as an active ingredient. Further, as a deodorizing method, it comprises the step of contacting the deodorant described above with the deodorant. As described above, the deodorizing method can achieve contact with the deodorant by spraying the deodorant. In the above-described deodorizing method, the deodorant is brought into contact with the deodorant, the surrounding environment becomes an anaerobic environment, the anaerobic decomposition of the deodorized substance is performed, and then the surrounding environment is changed to become an aerobic environment, and the odor is removed. Aerobic decomposition of deodorant. Further, as a sludge decomposition method, the step of contacting the above-described deodorant with sludge is included. Further, as an organic matter decomposition method, the method comprises the steps of contacting the above-mentioned deodorant with an organic substance. Furthermore, as claimed in claim 1, the deodorizing member has a zeolite having a heat-resistant actinomycete, Pseudomonas aeruginosa, C. mobilis, Sphingomonas, Acinetobacter The microbial population of Nitrosomonas and Nitrobacter is contacted, and the deodorizing member is characterized in that the zeolite is filled in a gas-permeable and/or liquid-permeable bag. The deodorizing member according to the first aspect of the invention, wherein the shape of the bag body is a sheet shape, a mat shape or a rod shape. Further, the creation of the third aspect of the patent application is a deodorizing device comprising: a deodorizing tower; a deodorant introduction port and a discharge port provided in the deodorizing tower; and being disposed inside the deodorizing tower, At the same time, in contact with the deodorant, a nozzle for allowing the liquid to spray in a direction opposite to the direction in which it is made; and any place disposed inside the deodorizing tower as claimed in the patent scope 1 Or 2 deodorizing components. For example, in the creation of the fourth aspect of the patent application, the deodorizing device described in claim 3 is provided with a circulation path for returning the liquid sprayed from the nozzle and contacting the deodorized material to the nozzle again. . For example, the deodorizing device described in claim 3, which is provided with a granular layer which can slow down the deodorant inside the deodorizing tower. Furthermore, as a composting accelerator, a microbial population containing heat-resistant actinomycetes, Pseudomonas aeruginosa, C. mobilis, Sphingomonas, Acinetobacter, Nitrosomonas, and Nitrobacter Active ingredients.

The deodorant is an active ingredient containing a microorganism group belonging to Actinomyces of the genus Streptomyces. Previously, no deodorant containing actinomycetes was present. The reason is because the adverse effects of actinomycetes on the deodorizing effect are common knowledge in the industry. According to the novel insights of the overturning conclusion that an extremely excellent deodorizing effect is achieved by a microorganism group containing actinomycetes belonging to the genus Streptomyces. Although it is preferable that the deodorant has a microbial group containing an actinomycete belonging to the genus Streptomyces, the microbial group preferably contains aerobic bacteria and anaerobic bacteria together. Further, it may include both Gram-positive bacteria and Gram-negative bacteria, or both cocci and bacteria. In addition, heat-resistant actinomycetes, Nocardia, aerobic bacteria, Pseudomonas aeruginosa, C. mobilis, Sphingomonas, Acinetobacter, and other nitrosated cells Bacteria, Nitrobacter, and thiobacillus are contained in the microbial population. Further, the actinomycetes belonging to the genus Streptomyces are preferably 5 to 50% in the deodorant.

Deodorants can take a variety of forms. For example, the microorganism group is dispersed in an aqueous medium (for example, water); the microorganism group is brought into contact with the zeolite to form a zeolite-microbial complex; the composite is dispersed in water; In any form, the concentration of the microorganisms, the ratio of the microorganisms to the zeolite, and the like can be appropriately determined in consideration of the odor intensity of the deodorant or the surrounding environment of the deodorant. Further, in the aqueous medium, various additives which do not adversely affect the microorganisms can be introduced as needed. Among them, the zeolite-microbial complex is a microorganism adsorbed in the porous body of the zeolite, and in order to increase the contact area with the deodorant, it is preferable to further improve the deodorizing effect. The zeolite to be used is not particularly limited, and a mordenite-based zeolite can be exemplified. The combination of the zeolite and the microbial group can be easily carried out, for example, by stirring the zeolite and the solid microorganism group in a suitable container in the case where the microorganism group is a solid (for example, a powder). In the case where the microbial group is dispersed in an aqueous medium, the zeolite can be simply combined by simply putting it into an aqueous medium.

Amazing deodorization can be achieved by contacting the deodorant with the deodorant. The contact form of the deodorant and the deodorant is not particularly limited, but may be described based on some specific examples.

The deodorant is the kitchen waste of the incineration plant or the fermenting tank-like solid in the composting field: the microbial group and the zeolite are dispersed in water, and the kitchen waste is directly sprayed. Further, in the case of the fermenting tank for composting, after dispersing the zeolite powder, the microorganisms dispersed in water are sprayed there.

In the case where the deodorant is a gas such as ammonia: The zeolite-microbial complex is filled in a gas- and/or liquid-permeable bag (for example, a non-woven fabric), and this (deodorizing member) is placed in contact with the odor generated from the deodorant. At this time, the shape of the bag body can be variously determined depending on the installation place, but it may be a sheet shape, a mat shape or a rod shape. In addition, the zeolite is filled in the bag body in advance, and the microorganism group may be dispersed in water or the like immediately before use, and may be dispersed in the zeolite to form a composite.

When the deodorant is a sewage-treated water or a manure-treated liquid, a treated liquid is introduced after the deodorizing member is disposed at the bottom of the storage tank for treating the water. Alternatively, the microbial population and zeolite are dispersed in water to be directly dispersed in the treated water. As described above, the deodorant may be any one of a gas, a liquid, and a solid, and the deodorant may be directly contacted with the odor source and contacted with the gas generated from the odor gas source, for example, as a predetermined The odorous member may also be added to the liquid of the odor source. Further, the microbial population may be fixed in advance on the surface of the article to which the odor source may be attached.

A specific example will be described with respect to the case where the deodorant is a gas such as ammonia. Fig. 1 is a view for explaining the form of the deodorizing member using the present invention in the water washing and deodorizing tower. In the first diagram, the deodorizing tower 11 is provided with a deodorant introduction port 12 and a discharge port 13. The deodorant (primary odor) will move from the inlet port 12 to the upper side of the discharge port 13. Inside the deodorizing tower 11, a nozzle 14 capable of spraying a deodorant is provided, and the sprayed deodorant will flow through the water tank 15 at the bottom of the deodorizing tower 11. That is, the sprayed deodorant flows in the opposite direction with respect to the direction in which the original odor is performed. Further, inside the deodorizing tower 11, the nozzle 14 is held, and the granular layer 16 is placed up and down, and the original odor is turbulent due to the granular layer 16, so that the contact time with the deodorant becomes long. Enter one The deodorizing members (pad 17 and rod 18) created by the step are disposed in the granular layer 16. As shown in Fig. 1, the mat 17 is provided in a layered shape, and the rod 18 is placed at any place. The deodorant is first supplied to the water tank 15 and sprayed from the nozzle 14 by the circulation pump 19. The deodorant sprayed from the nozzle 14 and in contact with the original odor flows through the water tank 15, and is again sprayed from the nozzle 14 by the circulation pump 19 together with the re-supplied deodorant. In this way, the deodorizing tower 11 is provided with a circulation path, and the deodorant is stored in the water tank 15 by spraying, and returns to the nozzle 14 again.

In addition, the deodorant is brought into contact with the deodorant, and the surrounding environment is set to an anaerobic environment to cause anaerobic decomposition of the deodorant, and then the surrounding environment is changed to an aerobic environment, and the deodorant is removed. Aerobic decomposition, and the deodorization of the deodorant can be further performed well. In this case, it is necessary for the microbial population to be aerobic bacteria. This method can suitably adopt a sewage treatment system like a settlement drainage treatment system. Here is an example to illustrate this system as follows.

Fig. 2 is a view for explaining the use of the settlement drainage treatment system of the present invention (for example, based on the system of the clean center of the settlement of the northern part of the village of Nakagawa-mura, Nagano Prefecture, Japan). The inflowing treated water is placed in the aerated grit tank 21 through a coarse screen, and then sent to the flow rate adjusting tank 22. The treated water taken out from the flow rate adjusting tank 22 is used to measure the treated water to be treated by the sewage metering tank 23, and the deodorant is introduced in step 24. Next, the treated water is advanced to an anaerobic filter bed tank 25, and the microorganisms are subjected to decomposition of the organic matter in the treated water. Then, the treated water is moved to the contact aeration tank 26, and the aerobic bacteria contained in the microorganism group further decompose the organic matter. Contacting one of the treated water contained in the aeration tank 26 Some can also be returned to the anaerobic filter bed. The treated water is then passed to a precipitation tank 27 where the sludge is precipitated and the liquid portion is sterilized by the sterilization tank 28 and discharged. The precipitated sludge is further concentrated in the sludge concentration storage tank 29 and transported to the sludge storage tank 30. In the second embodiment, the sludge storage tank 30 includes a first chamber 301 and a second chamber 302. According to one embodiment, a deodorant is further added to the sludge storage tank 30. The deodorant also has the ability to decompose the sludge and reduce it. After the sludge is decomposed, the liquid portion of the sludge storage tank 30 is again sent to the flow rate adjusting tank 22, and the same steps as described above are repeated. The cycle is preferably repeated three times to reduce the sludge by at least 30% compared to the previous steps. Further, as described above, the amount of the deodorant to be added is preferably determined in consideration of the scale of the wastewater treatment system, the degree of contamination of the treated water, the treatment speed of the treated water, the ambient temperature, and the like.

Example:

Further explanation will be given below based on the examples. Further, the deodorant used in the following examples contains an actinomycete from the fertile soil of the northeast region as a dominant group of microorganisms, which contains Streptomyces, and other actinomycetes, heat-resistant actinomycetes, Gram Bacillus subtilis, Arthrobacter, Mycobacterium, Pseudomonas aeruginosa, P. mobilis, sphingosine in the case of Gram-negative bacteria Monocytogenes, Acinetobacter, Nitrosomonas, Nitrobacter. Further, the microbial group is dispersed in water and has a bacterial count of about 1 × 10 ⁶ /ml. Further, as a result of experiments by the creator, it has been found that the deodorant maintains the same flora as a liquid agent over a long period of time (1 to 2 years).

Example 1:

In the step 24 of the sewage metering tank 23 of the settlement waste sheet of the northern part of the waste water treatment plant of Nakagawa-mura, Nagano Prefecture, Japan, which has the same equipment as in Fig. 2, a deodorant is introduced. The introduction Japanese introduced the deodorant at a ratio of 1 liter per day from May 14 to August 21, 1998. After the introduction, the measurement items shown in Table 1 below were measured in the second chamber 302 of the sludge storage tank. The results are shown together in Table 1. In addition, the MLSS (sludge concentration) of the second chamber 302 of the sludge storage tank when the deodorant was introduced was measured in the same manner as above from April to August 1998 in the Yamanouchi Sewage Treatment Plant in Nagano Prefecture, Japan. SV (activated sludge sedimentation rate), SVI (sludge capacity index) and excess sludge volume. The results are shown in Table 2. For the sake of comparison, the data for the year 1997 in which the deodorant was not introduced was also recorded.

From the results of Table 1, it was confirmed that the decomposition effect of the sludge was remarkable and the effect of reducing the H ₂ S which is one of the malodor sources. Further, as is clear from the results of Table 2, by introducing a deodorant, the SV, SVI, and excess sludge amount can be surprisingly improved. Further, in Table 1, from the data of the sludge concentration (6200 ppm) on May 15 and the sludge concentration (1200 ppm) on August 21, the organic matter digestion reduction rate was 84%. In addition, the organic matter digestion reduction rate (the sludge concentration on May 15 × the total amount of sludge in the tank) is a, and (the sludge concentration on August 21 × the total amount of sludge in the tank) is b, which is defined as [ (ab) / a] × 100. Further, it is also known that the organic matter of the aerobic bacteria is decomposed in the deodorant, and the DO (dissolved oxygen amount) is preferably in the range of 0.5 to 2%.

In the case of the above-mentioned garbage dump in the northern part of the village of Nakagawa, Nagano Prefecture, Japan Based on the test results of the water treatment site, the reduction rate of dehydrated cakes in the purification center of Nagano Prefecture, Japan, and the Tatsuno-cho purification center in Nagano Prefecture, Japan are predicted. Table 3 (Japan Nagano Prefecture Eastern Town Purification Center) and Table 4 (Japan Nagano Prefecture Tatsuno Town Purification Center) indicate the respective results. In addition, the reduction rate in the table is regarded as the de-cement cake reduction rate, which is expressed as (mud cake reduction amount (t) - total occurrence amount) × 100. In addition, the actual sludge reduction rate was measured in the Nagano-Channo-cho purification center. As a result, the sludge reduction rate reached 46.4% in about two months from January 20, 2000, and almost no odor was felt.

Example 2:

Put 90 liters of kitchen waste into the container, and (i) untreated (blank group), (ii) before the kitchen waste is placed in the container, spray deodorant 3ml, (iii) before and after the food waste is placed in the container, spray and deodorize each 3 ml of the agent, (iv) 3 ml of the kitchen waste that had been placed in the container, and the degree of deodorization was investigated. The deodorization evaluation of this example was carried out according to the three-point comparative odor bag method (discharge method) of six persons of the odor appraisers. The results are shown in Table 5.

From Table 5, the excellent deodorizing effect of the deodorant can be confirmed. Especially in (iii) Before the food was placed in the container, 3 ml of the sample of the deodorant was sprayed, and an amazing deodorization was confirmed.

Example 3:

Seven glass containers of φ118 mm × 120 mm were each dispensed into 500 ml of sludge (solid content: 10%) in a sludge storage tank of the northern part of the waste water treatment plant in the village of Nakagawa-mura, Nagano Prefecture, Japan. One of the seven was used as a control group, and the mixture was well stirred. 50 ml of the filter paper was filtered, dried, and metered, and the weight of the residue remaining on the filter paper was examined. 6 residues, (i) 2 blank groups (anaerobic conditions or aerobic conditions), (ii) 5 ml of deodorant added (anaerobic conditions or aerobic conditions), (iii) addition 2ml of odorant (anaerobic conditions or aerobic conditions). Further, the aerobic conditions were ablower in a glass vessel, and air was aerated at a ratio of 0.12 kg/cm2 and adjusted. The test was carried out at room temperature of 25 ° C on the 7th day, and distilled water was added to the final day to adjust to a final amount of 500 ml. The weight of the residue of each sample was measured in the same manner as in the control group. The results are shown in Table 6.

From Table 6, the sludge decomposition effect of the deodorant can be confirmed.

Example 4:

Laboratory-grade deodorization experiments were carried out using sludge with a high degree of acetic acid odor. 25 ml of sludge is placed in a polyethylene container (with cover) of φ80 mm × 100 mm, (i) without any treatment (blank group), (ii) 2 ml of spray deodorant, (iii) deodorization of 2 ml The agent and the deodorizing member are placed so as not to contact the sludge, and (iv) only the deodorizing member of the present invention is placed in contact with the sludge to investigate the degree of deodorization. In addition, the above-described deodorizing member means that the mordenite-based zeolite is placed in a non-woven fabric to be 100 g/m 2 , and the deodorant is sufficiently adsorbed and adjusted to a size of 4 mm × 4 mm. The degree of deodorization was investigated according to the paneler's panel in terms of 6-stage odor intensity. Further, the acetic acid concentration was measured by a gas detecting tube manufactured by K.K., and the initial pH of the sludge was measured based on litmus test paper. Further, the test was carried out immediately after the start of the test, after 1 hour, after 3 hours, and after 24 hours. The results are shown in Tables 7 and 8.

From the above results, it is understood that by using the deodorizing member of the present invention, a remarkable deodorizing effect can be achieved immediately after the start of the test.

Example 5:

Deodorant is applied to the grease trap in the restaurant to investigate the content of n-hexane extract, biochemical oxygen consumption (BOD), float mass (SS) and hydrogen in the treated water treated. Ion concentration (pH). Further, the oil separator had a capacity of 250 liters (W50 cm × L 100 cm × H 750 cm), and before the above test, 4 liters of the deodorant was sprayed in the entire oil separator. The results of the treatment of water one month after the spraying were investigated as shown in Table 9. Further, the content of the n-hexane extracting substance, the biochemical oxygen consumption (BOD), the mass of the suspended matter (SS), and the hydrogen ion concentration (pH) of the treated water before the application of the deodorant are also shown in Table 9.

From the results of Table 9, it is understood that there is also a significant degreasing effect in the deodorant.

Example 6

Further, in the present invention, the above deodorant can be used as a composting accelerator. The microbial group similar to that of Example 1 was made into a composting accelerator (described in the following table as All-Dash Soft), and a composting experiment of the sludge cake (sludge dewatering cake) produced by the drain treatment was performed. Figure 3 is a view for explaining the composting apparatus used in the present embodiment. Further, the composting apparatus of Fig. 3 is a general apparatus and is widely known in the industry. In the third embodiment, the composting device 41 includes a sludge dewatering cake inlet 42 and a full-flavour composting port 43 and has a stirring means 44 therein. The deodorizing device 45 and the warming device 46 are further provided. The stirring means 44 is rotated in accordance with the driving means 47. The rotation speed is set to 30 seconds per rotation. Further, the capacity of the composting apparatus used in the present embodiment is 50 to 60 liters, and the compost is indicated by 48. Next, using the apparatus shown in Fig. 3, the composting test of the sludge dewatering cake was carried out under the conditions shown in Tables 10 and 11 below. The test days were December 1999 (Table 10) and January 2000 (Table 11). The results are shown together in Tables 10 and 11.

As a result, a reduction rate of 36.89% (Table 10) and a reduction rate of 54.70% (Table 11) were obtained, and it was confirmed that the composting agent was excellent in composting promotion.

The deodorant is not dangerous or harmful to the human body according to the research of the present creator, and is biodegraded even after being discarded, and has almost no adverse effect on the environment. Further, the above is a deodorant which contains a microbial group belonging to the actinomycetes of the genus Streptomyces as an active ingredient, but the deodorant member and the deodorizing device, even if other microbial groups are used, The prior art can achieve good results.
