Description

[Technical Field]

[0001] The present invention relates to a wastewater treatment system that uses an environmental pollution cleanup aid. The wastewater treatment system of the present invention utilizes harmful substances and organic compounds contained in wastewater from factories, homes, commercial facilities, etc. by activating and multiplying microorganisms present in the treated water and the extracellular polymeric substances (EPS) they secrete, thereby enabling the emergence of microorganisms resistant to these pollutants. In particular, the system provides an active environment for anaerobic microorganisms, enabling the efficient decomposition of nitrogen, phosphorus, and sludge. [Background technology]

[0002] Wastewater from factories, homes, commercial facilities, etc. is mainly collected in activated sludge treatment tanks at sewage treatment plants, where it is treated. The activated sludge treatment method mainly uses aerobic microorganisms, which are activated by supplying air to the microorganisms in the aeration tank, and their action decomposes organic matter. Pollutants that cannot be treated are coagulated and precipitated in a settling tank using a flocculant to create sludge, some of which is returned to the aeration tank as activated sludge. The remaining excess sludge is extracted, dewatered and dried, and then incinerated or landfilled. The supernatant water is sterilized and discharged into rivers, etc. as treated water.

[0003] In activated sludge treatment, nitrogen, phosphorus, and other substances that are relatively difficult to decompose are coagulated and precipitated using a coagulant to create sludge, which is then disposed of.

[0004] Among the maintenance costs of sewage treatment plants, the costs of coagulants and nutrients for microorganisms, as well as the cost of disposing of excess sludge, are a major burden.In addition, problems such as carbon dioxide (CO2) emissions from the incineration of excess sludge and a shortage of landfill sites have also arisen. [Prior art documents] The majority of wastewater treatment systems used in wastewater treatment facilities around the world are activated sludge processes. [Patent documents]

[0005] [Patent Document 1] Patent No. 7082360 [Patent Document 2] Patent application 2023-143337 Summary of the Invention [Problem to be solved by the invention]

[0006] In conventional activated sludge processes, large amounts of coagulants and nutrients for microorganisms are used to meet various wastewater standards, resulting in the generation of large amounts of sludge.

[0007] The present invention has been made to solve the above problems, and aims to provide a wastewater treatment system that meets wastewater standards without using coagulants or nutrients and does not generate sludge. [Means for solving the problem]

[0008] The environmental pollution remediation aid used in this invention is a mixture of chopped fruit pieces rich in proteolytic enzymes that break down proteins into amino acids, fruit rich in carbohydrate-degrading enzymes that break down carbohydrates into glucose, and fruit rich in lipolytic enzymes that break down fats into fatty acids; yeast rich in amino acids that activate and promote the growth of resistant bacteria that partially decompose organic matter, chemicals, and inorganic matter present in the contaminated area and the extracellular polymeric substances (EPS) they secrete; black vinegar mash; B vitamins that function as catalytic coenzymes; glucose; and citric acid.By continuously dripping or spraying this aid onto the contaminated area, the number of microorganisms present in the contaminated area is increased by activating and utilizing the extracellular polymeric substances (EPS) that they secrete. Furthermore, the catalytic action of the enzymes and coenzymes continuously promotes the decomposition of contaminants by microorganisms, improving remediation efficiency.

[0009] Pineapple, kiwi, green papaya, melon, apple or ginger can be used as the fruit containing a large amount of enzymes that decompose proteins.

[0010] The fruit containing a large amount of carbohydrate decomposing enzymes may be radish, cabbage, banana, yam, or ginger.

[0011] The fruit containing a lot of lipolytic enzymes may be avocado, radish, turnip, grapefruit or orange.

[0012] The wastewater treatment system of the present invention comprises an aeration tank equipped with a dripping device for dripping an environmental pollution purification aid into the aeration tank and the normal anaerobic tank, a nanobubble generator, a normal anaerobic tank, an absolute anaerobic tank, and a final settling tank.

[0013] By supplying nanobubbles to the aeration tank, aerobic microorganisms are activated and multiplied more efficiently, accelerating the decomposition of organic compounds. Furthermore, the use of nanobubbles can reduce electricity costs by approximately 30% compared to conventional systems.

[0014] The environmental pollution purification aid is dripped into the aeration tank and the regular anaerobic tank. The functionality of the environmental pollution purification aid activates and multiplies the microorganisms in each tank, while the catalytic action of enzymes and coenzymes allows the microorganisms to efficiently decompose harmful substances and organic compounds.

[0015] In a normal anaerobic tank, many clumps of microorganisms (flocs) that have been activated and multiplied in the aeration tank float. In the activated sludge method, a flocculant is used to flocculate and settle the sludge, and some of it is returned to the aeration tank. The remainder is disposed of as discharged sludge. In the wastewater treatment system of this invention, no flocculant is used, so the floating flocs are collected using an oil fence or similar and returned to the aeration tank using a pump or similar. This is an activated floc method that replaces the activated sludge method.

[0016] The wastewater treatment system of this invention provides an anaerobic tank (underdrain) to create an environment conducive to the activity of anaerobic microorganisms, which efficiently decompose nitrogen, phosphorus, and sludge. As a result, sludge can be eliminated while meeting wastewater standards without the use of coagulants.

[0017] By using precast box culverts and Hume pipes manufactured in factories, construction time and costs can be shortened. [Effects of the Invention] The wastewater treatment system using the environmental pollution purification auxiliary of this invention does not require flocculants or nutrients, as compared with the conventional activated sludge method, and does not produce discharged sludge, making it possible to significantly reduce the maintenance costs of wastewater treatment plants.

[Figure 5] FIG. 2 is a detailed view of the dripping device for the environmental pollution cleanup auxiliary. DETAILED DESCRIPTION OF THE INVENTION An example of an embodiment of a wastewater treatment system using the environmental pollution purification auxiliary of the present invention will be described with reference to the drawings.

[0019] <Overview> FIG. 1 is a flow diagram illustrating the mechanism by which pollutants in a polluted area are decomposed and purified by the environmental pollution purification adjuvant used in the present invention. The environmental pollution remediation adjuvant used in this invention is continuously dripped or sprayed onto a polluted area to increase the extracellular polymeric substances (EPS) secreted by microorganisms present in the polluted area, promoting the formation of a biofilm, thereby efficiently cultivating and multiplying the microorganisms in the biofilm and increasing the number of microorganisms in the polluted area, thereby promoting the decomposition of pollutants.It also uses enzymes (protease, carbohydrate-degrading enzyme, lipolytic enzyme) to break down and fragment proteins in organic matter into amino acids, carbohydrates into glucose, and lipids into fatty acids, thereby reducing the molecular weight and making them easier for microorganisms to absorb, thereby promoting the decomposition of organic matter.Furthermore, the catalytic reaction of the enzymes increases the probability of contact between microorganisms and pollutants, promoting the decomposition of pollutants by microorganisms, and promoting chemical reactions such as oxidation and reduction reactions and photosynthesis in living organisms.These synergistic effects create an active environment for microorganisms involved in the decomposition of pollutants in the polluted area, promoting the decomposition of pollutants, and making the water purification adjuvant continuously purify the polluted area.

[0020] Figure 2 is a basic diagram of a sewage treatment system that uses the conventional activated sludge method and the environmental pollution purification aid of the present invention. In the activated sludge method, air is supplied to the raw water that flows into the aeration tank, mainly activating and multiplying aerobic microorganisms, which then decompose the organic matter in the raw water through the action of these microorganisms. The remaining pollutants are then coagulated and precipitated in the subsequent settling tank by the addition of a coagulant, producing activated sludge, some of which is returned to the aeration tank. Excess sludge is extracted, dewatered, dried, and then disposed of. The supernatant water is discharged into rivers, etc. as treated water.

[0021] In contrast, the wastewater treatment system that uses the environmental pollution purification aid of this invention supplies air in the form of nanobubbles to aerobic microorganisms in the aeration tank. By supplying nanobubbles, the aerobic microorganisms are more efficiently activated and multiplied, promoting the decomposition of organic compounds. Furthermore, the use of nanobubbles can reduce electricity costs by approximately 30% compared to conventional systems. The environmental pollution purification aid is dripped into the aeration tank and the regular anaerobic tank. The functionality of the environmental pollution purification aid activates and multiplies the microorganisms in each tank, while the catalytic action of enzymes and coenzymes allows the microorganisms to efficiently decompose harmful substances and organic compounds. In a typical anaerobic tank, clumps of microorganisms (flocs) that have been activated and multiplied in the aeration tank float in large numbers. Since the wastewater treatment system of this invention does not use coagulants, the floating flocs are collected using an oil fence or similar and returned to the aeration tank using a pump or similar. In the wastewater treatment system of this invention, an anaerobic tank (underdrain) is provided to create an environment conducive to the activity of anaerobic microorganisms, which can efficiently decompose nitrogen, phosphorus, and sludge. As a result, sludge can be eliminated while meeting wastewater standards without the use of coagulants. The supernatant water from the final settling tank is discharged into rivers, etc. through a drainage ditch.

(a) is a photograph of the drip tank and dripping situation. (b) and (c) are photographs of the occurrence of flocs (clumps of microorganisms) in a sedimentation tank. In the sewage treatment system of the present invention, these flocs are accumulated using an oil fence or the like, pumped up, and returned to the aeration tank as return flocs.

[0025] A wastewater treatment system that uses the environmental pollution purification adjuvant of this invention contributes to reducing maintenance costs such as the cost of coagulants and nutrients, sludge disposal costs, and electricity costs compared to current activated sludge method wastewater treatment plants.It also contributes to combating global warming by reducing the CO2 generated when producing these materials and electricity and when incinerating sludge.
