Description

  The present invention relates to a sludge odor elimination method and a method for decomposing sludge from the seabed, etc., using a metal oxide mixing structure unique to the present application.

  In order to remove the bad odor generated from waste sludge and livestock manure, many methods have been proposed to decompose organic substances into biogas and moisture, but the decomposition process is complicated. However, since the operation requires a large amount of heat, the cost is excessively high, and there is a problem that requires a considerably high cost.

  Furthermore, because the biomass used varies depending on the seasons, the production season was limited, the operation rate was as low as 30% to 40%, and the production efficiency was also poor.

  Moreover, it is very difficult to decompose the sludge on the seabed, and the installation of fishing reefs in the so-called sludge area is ineffective, and the growth of fish and the regeneration of seaweeds are almost impossible.

  The present invention does not require heat in the decomposition process and can produce biogas throughout the full season, significantly improve the operation rate, and make the biomass device small to significantly reduce the production cost from the conventional range. It is aimed at.

  The present invention does not require any heat in the production process, so that silicon oxide, aluminum oxide, iron oxide, potassium oxide, titanium oxide, calcium oxide, magnesium oxide, sodium oxide, manganese oxide, and a small amount of barium oxide. , Chromium oxide, phosphorous oxide metal oxides are mixed into a so-called geopolymer, filled into a mesh cylinder and put into a malodorous product. Each metal oxide is characterized by easily decomposing malodor and sludge generated from waste sludge and livestock manure into biogas and moisture.

  Furthermore, what was produced as a culture plate was installed in a so-called sludge area on the seabed as a fishing reef, so that the sludge was decomposed in a short period of time, and the growth of fish and the reproduction and growth of seaweeds in a short period of time again. It creates an ecosystem. Therefore, it produces oxygen, fixes carbon dioxide, and has a water purification effect.

  Since the present invention does not require heat in the decomposition process and can produce biogas throughout the full season, the operating rate is remarkably improved to 70% or more, and the biomass apparatus can be made in 1/30 of the conventional one. Moreover, the production cost can be reduced to 1/30 of the conventional common sense range and to 1/50 or more on the industrial base.

  The features of the present invention are that the mesh cylinder has a small body size, is extremely easy to install, has a very low running cost, and exhibits a comfortable and expensive price.

  The present invention decomposes and removes sludge and odors and deodorizes them, drastically destroys sludge and odors generated from waste, drastically improves the decomposition rate of seabed sludge and sewage, and can treat hardened sludge as sewage In addition to preventing the settling of sludge, it is compact, extremely easy to install, low in installation cost, compatible with all sewage treatment equipment, and has a very low running cost. .

  Since the present invention is based on non-explosive air and does not require thermal energy for biogas with an operating rate of about 30%, which requires conventional heat, the operating rate is improved to 70% and anaerobic. It has the effect of remarkably activating the genus fungus. By creating a porous plate that sinks in the seabed, it is possible to decompose the seabed sludge and to create a new ecosystem by installing it as a fishing reef. There is an effect that can be.

  It is a perspective view of the whole charging case of this invention.   It is a perspective view of the mesh cylinder of the present invention.   It is a perspective view after two weeks progress of the algae grass board sunk in the seabed.   It is the perspective view after one month progress of the algae grass board sunk in the seabed.

  The present invention does not require any heat in the production process, so that silicon oxide, aluminum oxide, iron oxide, potassium oxide, titanium oxide, calcium oxide, magnesium oxide, sodium oxide, manganese oxide, and a small amount of barium oxide. , Chromium oxide, phosphorous oxide metal oxides are mixed to form a so-called geopolymer, which is filled into a mesh cylinder and put into a malodorous product. Each metal oxide comes into contact with waste sludge, livestock manure, etc., and synergistically emits electromagnetic waves specific to each, so that malodors and sludge generated from sludge, livestock manure, etc. can be easily decomposed. It is characterized by removing malodors from biogas and moisture.

  As an example, the charging case (A) in FIG. 1 has a slight buffering action between the two left and right palates (2) and (2) reinforced by stretching a mandrel (1) in the center. The mesh cylinder (4) is further reinforced by the spiral frame (3), and the mesh cylinder (4) having a large number of holes in the peripheral wall is installed in the spiral frame (3). It was configured by filling a geopolymer (5) having a composition mixed with a metal oxide characteristic of the present application.

  By introducing this charging case (A) into the malodorous product, each metal oxide of the geopolymer admixture comes into contact with waste sludge or livestock manure, etc. It is characterized by the fact that it is released into the water and decomposes malodor generated from sludge and livestock manure to make biogas and moisture, thereby removing the malodor.

  In addition, concrete made with 3% to 60% of geopolymer mixed with 5% to 70% of crushed shells and made as an algae grass plate is installed in the sludge area of the seabed as a fishing reef. By decomposing, it was possible to grow fish and regenerate and grow seaweeds, and a new ecosystem could be created again. In addition, the same result was obtained even if it did not necessarily add a shell.

  As an example, in FIG. 3, a plate made by mixing 5% to 70% of a shell of 5 to 12 mm by weight with concrete mixed with the present geopolymer in cement (B). Was installed in the sludge of the so-called sludge area of the seabed as a fishing reef and seaweed grass making device, observed after 2 weeks, and the formation and growth of juvenile shellfish (6), seaweed grass (7) sparrow and elaco It was.

  Fig. 4 is an observation view of the algae grass plate (B) installed in the sludge of the so-called sludge area on the seabed after one month has passed, and the adhesion growth of juvenile shellfish (6) and seaweed grass (7) is remarkable. It can be seen that the growth and growth of seaweeds on concrete blocks, which normally takes 5 to 6 years, was promoted in a very short time.

  That is, in the algae grass plate (B), sludge is decomposed in a very short period of time by dissolution of the geopolymer composition component and the specific energy of the mineral, and the algae grass plate (B) is transformed into juvenile shellfish (6) and seaweed grass. The (7) epiphytic marine plants were cultivated, and it was demonstrated that fish could be proliferated and seaweeds regenerated and prospered, and that a new ecosystem could be created again in a short period of time.

  In general, the mechanism of bacterial degradation includes a degradation process consisting of an aerobic bacterium that requires air, a dual-purpose bacterium that does not die without air, and an anaerobic bacterium that does not work when air is present. , Which uses anaerobic bacteria that produce biogas without sending air, and moves the anaerobic bacteria to produce methane.

  In the present application, the inherent energy generated by the geopolymer, which is a mixed composition of metal oxides, activates anaerobic bacteria and destroys sulfa, which decomposes and eliminates the odor of sludge.

  In the present invention, since no heat is required in the decomposition process, biogas can be produced throughout the full season. Therefore, the operation rate, which has been low as 30% to 40% in the past, can be remarkably improved to 70% or more. The device can be made in 1/30 of the conventional one, and the production cost can be reduced to 1/30 of the conventional common sense range or 1/50 or more on an industrial base.

  As for the malodorous substance concentration, the calculation results in Table 1 were obtained for each target as compared with the concentration before the contact treatment.

The oxygen demand in the materials was calculated as shown in Table 2.

  In the experiment method, the geopolymer of the present invention was introduced into the tank below the slat of the pig house and the attached equipment, and the change over time in the pig house odor was observed. In Table 1, the concentration of ammonia, which is the main malodorous substance, is 21.9 ppm before contact treatment, 5.5 ppm after contact treatment, and the concentration of hydrogen sulfide is 0.8. It was significantly reduced to 0, 21 ppm with respect to 55 ppm.

The biochemical oxygen demand was significantly reduced from 34000 mg / l to 62 mg / l.
