The present invention relates to a method for highly treating sewage and wastewater by culturing microorganisms that generate corrosive substances and converting them into stable corrosive (bulb) materials.

Japanese Patent Publication In the case of 5-66199, humic soil was processed into pellets, and bioreactors filled with rhyolite or pumice pumice were installed in the culture tank, and humus soil was treated in the treatment of wastewater containing organic substances. And in the case of wastewater having a low content of iron 4, trioxide, or a low Oxidation Reduction Potential (ORP) value among pumice stones, there is a problem that treatment efficiency is not improved.

The present invention is to provide a method that can be highly treated treatment of sewage and waste water by maintaining the optimum environmental conditions of the corrosive substances generated microorganisms and microorganisms in mutual symbiosis in the culture tank and aeration tank to solve the above problems. It is an object of the present invention.

In order to achieve the above object, the present invention provides a caustic earth with a high content of fulvic acid, and adjusts the acidic corrosive colloid micelle to acid to induce fulvic acid to a free state and then magnetize magnetite powder.

By cultivating microorganisms and microorganisms with mutual symbiosis, it is economically advanced treatment of organic pollutants in sewage and wastewater.

The acidic marine corrosive colloidal micelle used in the present invention is a humus soil in which marine animals, plants and diatoms are mixed and deposited with acidic ash or minerals, and activated alumina in volcanic ash or minerals (Al _2). O ₃ ), silica (SiO ₂ ) and other minerals are released as hydrogen ions (H ⁺ ) by water and hydrolysis reaction to form a strongly acidic soil, and fulvic acid is present in the free state. Therefore, various mineral components exist in the form of chelate mineral complex salts.

Bacillus mycoides, Aspergillus niger, Penicillium glaucum, and Sour, which have active metabolism when mineral supply is sufficient Corrosion that converts organic substances into corrosive substances by excretion of polyphenolic metabolites such as actinomycetes, such as Sorangium cellulosum and Actinomyces globioporus roseus Microorganisms that interact with symbiotic organisms and these microorganisms are active, while growth of pathogenic microorganisms and rot and decaying (anaerobic) microorganisms which are antagonistic with these microorganisms is suppressed.

In particular, in the case of colloidal micelles containing a large amount of chelate iron fulvate, which is formed by the reaction of magnetite magnetite with fulvic acid, these microbial metabolism activities become more active.

In addition, the marine corrosive colloid micelles contain a large amount of physiologically active substances, growth accelerators and other active enzymes necessary for the growth of microorganisms, thereby promoting the growth of these microorganisms.

Therefore, marine corrosive acid colloid micelles (such as hydrochloric acid (HCl) or sulfuric acid (H ₂ SO ₄ )) 을) by injecting Fulvic acid into the free state by adjusting the pH to 2.3 or less, and then magnetizing magnetite with a magnetization of 400 G or more (Gauss) capable of magnetic flux density.磁 ) 4 to 10 wt% of powder ground to 40 to 60 µm, mixed with hornblende, olivine, rhyolite, or large-sided pumice stone. Crude minerals that easily elute minerals in water. Chelated iron fulvate and other organic acids after mixing powders alone or in combination of two or more kinds, pulverized to about 40 to 60 탆, and mixed at an organic / inorganic ratio in the range of 0.8 to 1.2, for at least one month. After conversion to mineral complex salt form, it is molded into pellet form and dried.

Magnetic magnetite generates magnetic fluid dynamics (MHD) when water (fluid) flows between the magnetic fields of magnetic magnetite (magnetic material), and water, which is a weak electrolyte, is electrolyzed. ) Oxygen is generated, -The hydrogen is generated at the potential side, and the active oxygen is stabilized by oxidizing reducing substances such as organic substances and perishable substances, and also the wave of electrons as water passes through the magnetic field of magnetite. Group of water molecules ; As the microstructure becomes smaller, surface tension is reduced, so that penetration force is improved, solubility is improved, deodorization efficiency is improved, and cell membrane permeability of microorganism is improved, so that metabolic activity of microorganism is enhanced. Let's do it.

In addition, minerals are hornblende, olivine, rhyolite or luteite-like pumice and biotite, which are easy to elute various minerals by weathering. Black stone, obsidian, pearl rock Stone, Songji rock, Rhyolite or Dacite, Pumice, Lake stone, Giant stone, Cheonmae rock ), Elvan Use at least one kind of mineral such as 石.

Hereinafter, the contents of the present invention will be described in detail with reference to the drawings.

In the case of aerobic biological treatment of sewage and wastewater, as shown in Fig. 1, part of the return sludge of the sedimentation tank in the general activated sludge treatment process contains a large amount of magneto-optic powder and soluble mineral component magnetized with a magnetic flux density of 400G or higher A mixture of powdered coarse mineral powder was formed into pellets and magnetized ingots magnetized with a magnetic flux density of 400 G or more. Iv) and mineral masses which are easy to elute various minerals by the above-mentioned weathering action. Polyphenol metabolism is sent to the culture tank (1) equipped with a bio-reactor (2) filled with a filler (3), etc., and supplied with chelating mineral complex salts and other active enzymes. By excreting products, cultivating corrosive microorganisms that convert organic pollutants contained in sewage and wastewater into insoluble and nonvolatile corrosive substances in water, and microorganisms in mutual symbiosis with these microorganisms, and returning them to the aeration tank. The entire system is converted to an environmental atmosphere in which organic pollutants are converted to corrosive substances by the corrosion, and the water quality is purified.

At this time, in order to further improve the microbial culture efficiency, a permanent magnet or electromagnet having a magnetic flux density of 10,000 G or more magnetized on the discharge side of the culture tank circulating pulp 4 is used to culture the culture medium of the culture tank 1. By circulating the magnetic field of these magnets to supply magnetized water, and supplying the oxidized water of the disinfection oxidizing tank, the Oxidation Reduction Potential (ORP) value is adjusted in the range of +250 to +350 mV.

There are two cases in which the bioreactor 2 is installed in the culture tank 1 in the culture tank 1 as shown in FIG. 3 or outside the culture tank 1 as shown in FIG. 4.

When sewage and wastewater enter the collection tank, a part of the return sludge of the sedimentation tank is supplied to inject air from the blower to aeration to excrete the polyphenolic metabolite that converts the aforementioned organic substances into insoluble and nonvolatile corrosive substances. Corrosive microorganisms and microorganisms having mutual symbiosis with these microorganisms lead to the first decomposition and erosion reactions, leading to the reduction of odors.They are transferred to an aeration tank to infuse air and aeration to induce organic pollution in sewage and wastewater. The material is converted to a non-volatile corrosive (bulb) material and microbial cells that are insoluble in water and sent to the settling tank.

When it enters the sedimentation tank, solid materials such as corrosive (bulb) materials and microbial cells insoluble in the water are precipitated at the bottom of the sedimentation tank, and the blue water separated from the solid matter is fed to the sedimentation tank and sent to the disinfection oxidation process.

Solids (sludge) precipitated in the sedimentation tank are returned to the collection tank and the aeration tank for spawning, and some are sent to the culture tank to cultivate and activate the corrosive microorganisms and microorganisms having mutual symbiosis with these microorganisms as aeration tanks. When returned, the entire processing process system is converted to an environmental atmosphere treated by these microorganisms, and the surplus sludge is sent to a sludge treatment process (such as dehydration treatment).

Cheongdeung water from the sedimentation tank is sent to the disinfection oxidation treatment process to inject oxidants to oxidize untreated organic pollutants and sterilize the microorganisms and then discharge them. In order to adjust the ORP value in the range of +250 to +350 mV, it is returned to the aeration tank, the culture tank, and the collection tank.

In case of initial trial run or abnormal operation, magnetite powder mixed with marine corrosive acid colloid micelle magnetized with magnetic flux density of 200G or more is mixed with 4-10 wt%, and minerals such as natural stone, hornblende, olivine, rhyolite or pavement stone. The powder is mixed at an organic / inorganic ratio at a ratio of 0.8 to 1.2 and aged for at least one month, and injected into the sump, aeration tank, and culture tank in the range of 0.00006 to 0.06 wt% to stabilize the operation in a short time.

In case of high concentration organic wastewater such as livestock wastewater, food factory discharge wastewater, and manure, it is treated by two or more stages of multistage biological treatment process as shown in FIG. 2, wherein the corrosive microorganisms and microorganisms having mutual symbiosis with these microorganisms The culturing step (tank) is the same as the above-described process of Figure 1, the cultivation tank is installed at each stage possible.

Example 1

Corrosion-induced microorganisms that convert organic substances into insoluble and nonvolatile corrosive substances in water where 600m3 / day (average) of household wastewater discharged from apartment complexes are treated by the general activated sludge process The cultivation process as shown in Fig. 3 for culturing the microorganisms is applied to the process of Fig. 1, and about 10% of the inflow flow rate is injected into the culture tank with sludge returned from the settling tank, and the aeration time is maintained for 1.2 days. After cultivation and activation, the aeration tank was operated and the water quality of the treated water was highly treated as shown in Table 1, and the power consumption was reduced by 60%, resulting in a significant reduction in odor in the treatment plant.

EXAMPLE 2

The livestock manure discharged from the slurry pig sludge is dehydrated in the dehydration process, and then dehydrated filtrate 12-15m 3 / day is treated in a three-stage activated sludge process in the first and second stages as shown in FIG. As a result of installing and incubating the culture process as shown in Table 3, the treatment efficiency was greatly improved as shown in Table 2, and in particular, the odor was greatly reduced in the treatment plant.

As described above, in the present invention, the treatment by the corrosion reaction in the sewage and wastewater treatment due to the corrosion reaction has a significantly higher treatment efficiency than the general active waste treatment, and thus, the generation of odor is reduced and the operating cost is low. It is expected to be widely used for biological treatment of sewage and wastewater in the future.
