Description

  The present invention relates to a treatment agent for organic pollutants formed by microorganisms that can decompose organic substances (hereinafter referred to as “organic pollutants”) such as sea cucumbers, oils and fats, and other malodorous components, over a long period of time.

In recent years, in the natural world, lakes such as Lake Biwa are remarkably rich in nutritional value, accompanied by abnormal occurrences of blue-green algae, sea urchins, generation of off-flavors as well as landscapes, and ecological changes in fish and shellfish, etc. It has progressed to various social problems. In order to fundamentally solve this problem, it is necessary to improve the quality of water flowing into lakes and marshes, and it is necessary to reduce the inflow of pollutants, nitrogen and phosphorus. However, the current lake purification method is a method of collecting and incinerating the sea cucumber, which is a large-scale device and a heavy labor.
The above is the state of technological recovery of lake bottom sediments in closed freshwater areas such as lakes, but the effects of eutrophication also extend to closed seas. Abnormal growth and purification methods such as flagellate algae and diatoms called red tide are dealt with by collecting and incinerating diatoms in the same way as collecting and burning indigo.
In addition to lake water and seawater, the need for sterilization is everywhere, and spraying treatment methods using chlorinated chemicals are performed for this sterilization. However, it has the disadvantage of causing chlorophenolation in the presence of phenols to cause malodor, or being modified by a carcinogenic component to induce new environmental pollution.
On the other hand, in sewage pipes in the city and circulation piping in hydroponics, miscellaneous drainage organic pollutants and fertilizers adhere and accumulate on the inner wall of the piping due to oil and fat mixed in the drainage and circulating water, reducing the pipe diameter. There are also problems.

In order to solve these problems, Patent Document 1 proposes a method of using a biodegradable plastic derived from starch that decomposes and agglomerates water in the lake, settles and settles on the bottom of the lake, and then spontaneously disappears. Has been. However, the fixed single-piece plastic that decomposes and settles the watermelon has a risk of occurrence again unless the watermelon is completely decomposed. In addition, the bottom of the water has the disadvantage that it is difficult to understand the existence of the blue sea urchin, and long-term effects have not been confirmed.

  Accordingly, the present invention focuses on microorganisms that act as a blue-oil-degrading bacterium, and provides a technique that allows microorganisms to grow and maintain in large quantities over a long period of time, does not cause environmental pollution, and is not large in apparatus. .

  In order to achieve the above object, the treatment agent for organic pollutants according to claim 1 includes at least one fungus among filamentous fungi, actinomycetes, Bacillus subtilis, and yeast having an ability to decompose blue sea cucumber, A seaweed extract powder and baked sea salt are added to the fungus, an excipient of potassium hydrogen carbonate is added, and organic pollutants are decomposed.

  The treating agent for organic pollutants according to claim 2 is characterized by adding about 1 to 2% of seaweed extract powder for propagation of fungi such as filamentous fungi, actinomycetes, Bacillus subtilis and yeast.

  The treating agent for organic pollutants according to claim 3 is characterized by adding about 1 to 2% of baked sea salt for maintaining the long-term growth of fungi such as filamentous fungi, actinomycetes, Bacillus subtilis and yeast. And

  The treating agent for organic pollutants according to claim 4, while causing self-stirring that allows fungi such as filamentous fungi, actinomycetes, Bacillus subtilis and yeasts to peel off and float from the bottom of lakes and the inner walls of pipes. About 60 to 80% of potassium bicarbonate for movement is added.

  Since the treating agent for organic pollutants of the present invention uses microorganisms such as filamentous fungi, actinomycetes, Bacillus subtilis, and yeasts, environmental pollution does not occur. There is no need to use a large-scale device, and the water and oil can be decomposed by spraying tablets formed with the microorganism. In addition, since the microorganism is added with seaweed extract powder and baked sea salt, it can be propagated in a large amount and in the long term, and the lake and the piping can be purified over the long term. Since potassium hydrogen carbonate is contained in the tablet, water and oil can be easily decomposed and removed from the bottom of the water or the inner wall of the pipe. In the specified area, the effect of disintegration and withdrawal appears after administration of several tablets per week, and a long-term effect can be expected.

Embodiments of the present invention will be described based on Table 1 and FIGS. 1, 2, 3, 4, and 5. FIG. First, filamentous fungi, actinomycetes, Bacillus subtilis, and yeast that are raw materials of the present invention will be described.
Filamentous fungi, actinomycetes, Bacillus subtilis, and yeast are eukaryotic fungi that have a nucleus surrounded by a nuclear membrane with microorganisms used for various brewing, fermentation, and food industries since ancient times. These microorganisms are fungi possessing the ability to decompose blue sea urchin, and their behavior has attracted attention.
However, there is a case where sugar is used for the growth of the microorganism. Although this sugar has an immediate effect on the growth of the microorganism, it has a disadvantage that it is consumed quickly and its effect is lost immediately. is there.

Therefore, the present invention seeks to realize a composition that allows the microorganism to maintain the ability to decompose blue-green algae while growing for a long time.
Hereinafter, the composition as a microorganism retaining agent is shown in Table 1, and the function of each composition will be described based on this table.
Table 1 shows the composition when yeast is used among microorganisms such as filamentous fungi, actinomycetes, Bacillus subtilis and yeast. Seaweed extract powder, baked sea salt, potassium hydrogen carbonate and the like were blended in order to maintain the ability of decomposing blue-green algae for a long period of time.

Next, based on this composition table, the seaweed extract powder which is one of the compositions of the treatment agent for organic pollutants will be described.
Seaweed extract powder is a concentrated extract extracted from seaweed, containing a large amount of polysaccharides such as alginic acid, mannitol, laminarin, and various minerals, especially iodine, which are unique to seaweed, and also rich in vitamins, amino acids, plant hormones, etc. In addition, it provides nutrients for microorganisms such as yeast to grow over a long period of time. That is, conventionally, as described above, even if sugar is used for the growth of microorganisms such as yeast, there is an immediate effect, but consumption is sudden and the effect is lost immediately. In contrast, the seaweed extract of the present invention, as described above, contains polysaccharides and other minerals such as iodine, vitamins, amino acids, plant hormones, etc., and has the effect of promoting the growth of microorganisms such as filamentous fungi over the long term. Demonstrate. A reasonable amount is 1 ± 0.5%. If it is too much, the contained nitrogen, phosphoric acid, and potassium components will promote the growth of blue sea bream, and it will not be limited to the growth of microorganisms such as yeast.

Furthermore, the baked sea salt which is the 2nd composition of the processing agent of organic contaminants is demonstrated.
Baked sea salt is obtained by baking sea salt obtained from sea water at 800 ° C or higher, and its main component is sodium chloride, but it contains a lot of magnesium chloride, a bitter component, and the content of minerals is that of ordinary salt. There are seven times, and by baking, the nature of the salt is changed from neutral to alkaline, and the action of microorganisms to sustain life is promoted. As a result, microorganisms propagate in the long term due to a synergistic effect with the seaweed extract, and the amount of the baked sea salt is the same as that of the seaweed extract, and 1 ± 0.5% is an appropriate amount.

And if potassium hydrogen carbonate which is the 3rd composition of the processing agent of an organic pollutant is demonstrated, this potassium hydrogen carbonate will have the effect as a foaming agent, and the extinction effect of a phytopathogenic fungus.
When the potassium hydrogen carbonate is administered to water, the hydrogen carbonate ions that it holds are rapidly released into water and carbon dioxide gas, and its foaming power can stir fungi and nutrients in the lakes, resulting in a diffusion effect. Wake up. The sea bream sinking to the bottom of the water floats on the surface of the lake by its foaming power and diffusion effect, and can be decomposed by the microorganism.
Furthermore, potassium ion as a component exhibits a high therapeutic effect on plant pathogens and the like. The effect is fast-acting, and it has the effect of entering the cells of phytopathogenic fungi, disrupting the ion balance in the cells, causing damage to cell functions and eliminating lesions.

Finally, an excipient which is the fourth composition of the treatment agent for organic contaminants is added. The main components are succinic acid, PEG6000, and the like.

A purification experiment was performed on the pond of Lake Nasu Chifuri Country Club using the above-described microbial retention agent.

Blue spider was finely decomposed and turned brown, and transparency appeared in the pond. Further, for the sake of perfection, 20 treatment agents of the present invention were added immediately after this, and the next confirmation was awaited.
After that, the water in the pond increased its transparency and disappeared completely in the confirmation after 2 days later, and it seems that a little green spider is attached to the net stretching around the bottom of the pond, so it concentrates on that place 10 treatment agents of the present invention were added.
FIG. 3 shows the state of decomposition of blue sea bream and blue sea bream by microorganisms after 8 days from the experiment start date. The water quality has increased transparency, and the nets that looked thin can be clearly seen. Therefore, 10 treatment agents of the present invention were added for the future prevention and completed. Currently, the process of water purification is being monitored.

  Part of the fertilizer being circulated is stuck to the inner walls of the pipes used in hydroponics, and eventually all the pipes are filled with specific fertilizers as organic pollutants, and finally the fertilizer necessary for vegetables cannot be reached. A situation occurs where the vegetables are annihilated. In such a case, by using the microorganism-retaining agent of the present invention, not only the sea lions but also the organic pollutants that had blocked the inner wall of the pipe could be gradually dropped, and the physiological disorder of vegetables could be overcome.

The chemical fertilizer sticks to the inner wall of the pipe and solidifies, and in order to remove the solidified product, the treatment agent of the present invention is applied to the underground tank for 20 tons to which the hydroponics fertilizer is administered. 30 in the 3rd and 4th weeks, 20 in the 5th and 6th weeks, and 180 in total.
Then, three months later, the fertilizer turned into sludge flows out of the pipe, it becomes clean, the solidified material adhering to the inner wall of the pipe is peeled off, and all of the chemical fertilizer reaches the vegetables, and the growth of the vegetables is observed. I was able to. Concentration disturbance was caused by solidification of a part of chemical fertilizer.

As a measure against urinary stone in male toilets, the treatment agent of the present invention was administered to each urinal at a rate of one per week. Before and after the construction will be described with reference to FIGS.

FIG. 4 shows that the lid portion of the urinary tract opening in the urinal becomes difficult to remove due to being fixed with urine stones, and it is difficult to perform periodic cleaning. One treatment agent of the present invention was administered so as to hang on the lid, and follow-up was performed for 1 week.
One week after administration, as shown in FIG. 5, the redness around the lid disappeared, and the lid could be easily removed to facilitate cleaning.

If drainage is carried out in a state where a large amount of oil or fat is contained in the drainage, it will lead to clogging or damage to the water distribution pipe. In order to prevent this, fat and oil separators grease traps are installed in kitchens, etc. On the other hand, if maintenance of the grease straps is neglected, the fats and oils are transformed into sludge-like scum, and eventually the environment is destroyed. Various troubles occur such as bad odor, generation of pests, generation of pathogenic bacteria, environmental pollution.
Therefore, when the work in the kitchen was completed, 5 treatment agents of the present invention were administered into the grease wrap. Although depending on the degree of contamination, the effect appeared in about one week, and the dose was repeated while decreasing the number of administration in the next 2nd week and 2 in the 3rd week.
As a result, the fats and oils accumulated in the grease trap were decomposed and the deodorizing effect appeared in the administration number of 10 for 4 weeks after the administration.
