Abstract:
Periphyton filtration is a known method for performing bioremediation of polluted water. The present system (10) improves upon this method by adding a strong oxidizer, such as ozone from an ozone generator (18) to the influent, and in some cases to the effluent to make organically bound nutrients available to a target culture in a periphyton bed (24) or to aquatic plants to reduce the population of undesirable microinvertebrates and to make organically bound nutrients available to the periphyton. A pesticide (P) may be added to control insect populations.
Abstract:
Process and device for treating fluids polluted by harmful substances, which are difficult to decompose, by wet oxidation with ozone-containing gas and u/v irradiation. The device comprises injectors (6, 8) by means of which ozone-containing gas produced in an ozone generator (10) may be introduced into the fluid. The fluid is then fed into a reaction and degassing container (20) before being taken to the u/v irradiation units (40, 50).
Abstract:
본 발명은 오폐수 고도산화처리용 반응장치에 관한 것으로서, 더욱 상세하게는, 오존 및 과산화수소의 과잉 공급 없이 안정적으로 공급하면서도 오폐수와 효과적으로 혼합하여 오존(O 3 )/과산화수소(H 2 O 2 )(Peroxone AOP) 방식의 고도산화처리를 수행할 수 있는 오폐수 고도산화처리용 반응장치에 관한 것이다. 본 발명에 따른 오폐수 고도산화처리용 반응장치는 오존(O 3 )/과산화수소(H 2 O 2 )(Peroxone AOP) 방식의 고도산화처리를 수행할 수 있는 오폐수 고도산화처리용 반응장치에 있어서, 내부에 수용공간이 마련되도록 형성된 반응조본체; 상기 반응조본체의 내부에 설치되고, 상기 수용공간을 오폐수와 과산화수소가 유입되어 반응되는 제1 반응실과, 상기 제1 반응실과 연통되고 오존이 유입되어 오폐수와 반응되어 배출되는 제2 반응실로 구획하는 격벽; 상기 제2 반응실에 오존을 공급하기 위해 상기 반응조본체에 설치되는 오존 공급부; 및 상기 제2 반응실의 내부에 설치되고 오존과 오폐수의 반응 면적을 증가시키기 위한 다수의 폴링(Pall ring)이 내장, 형성된 폴링층을 포함하는 것을 특징으로 한다. 이에 의하면, 오존(O 3 )/과산화수소(H 2 O 2 )(Peroxone AOP) 방식의 고도산화처리 수행시에 오존과 과산화수소를 인젝터에 의해 혼합되는 방식이 아니라 반응조 내부에 오존과 과산화수소를 오폐수의 유량에 따라 적절하게 공급하여 유기물을 제거하는 방식이므로 운전비용이 절감되고, 오존 및 과산화수소의 과잉 공급으로 인한 유기물의 산화 효율 저하를 방지할 수 있어서 유기물의 제거효율이 향상되는 효과가 있다.
Abstract:
The present invention relates to a water treatment apparatus using ozone and ultrasonic wave, including an ultrasonic wave reaction bath that has a first inlet into which polluted water flows in, a water collection bath which collects the treated polluted water, a first discharge port which discharges the finally treated polluted water, multiple ultrasonic wave vibrators which irradiate ultrasonic wave, and an ozone water supply pipe which supplies ozone water transported from an ozone mixing unit to store and treat the polluted water; the ozone mixing unit that has an air diffusion device so that the polluted water, which is treated in the ultrasonic wave reaction bath, flows in and is converted into the ozone water before being discharged to the ultrasonic wave reaction bath; an ozone generator that generates ozone and supplies the ozone to the air diffusion device of the ozone mixing unit; a first transport pipe that transports the polluted water which is treated in the ultrasonic wave reaction bath from the water collection bath of the ultrasonic wave reaction bath to the ozone mixing unit; and a circulation pump that is connected to the first transport pipe and supplies polluted water transport power.
Abstract:
The present invention relates to a plasma water treatment system having a dissolver. Both ends of an electrode tube are connected to a gas inlet of a first cap and an ozone outlet of a second cap. The electrode tube is wound like a coil to increase the contact between the gas passing in the electrode tube and first and second electrodes. The second electrode is embedded in the coil-type electrode tube to increase the contact amount and contact time with the gas passing the electrode tube. Thus, the gas introduced into the electrode tube is exposed to the first and second electrodes as much as possible by delaying the discharge time of the gas while the gas passes the coil-type electrode tube. The coil-type second electrode is arranged inside the electrode tube to be exposed inside the electrode tube as much as possible; thereby maximizing the generation of ozone.
Abstract:
The present invention relates to an apparatus and a method for producing drinking water and cooling water for ships using seawater. The present invention includes an ozone generator (10) that generates ozone; a mixing pump (20) that takes in seawater, mixes the seawater with the ozone which is generated by the ozone generator (10), and produces and discharges treated water in a supersaturated state; an ozone sterilization device (30) that sterilizes the treated water which is discharged through the mixing pump (20) by using ozone and ultrasonic waves; a reaction filter (40) that passes the treated water which is sterilized by the ozone sterilization device (30) through a filter with a double-layer structure to filter bacteria and contaminants remaining in the treated water; a reservoir tank (50) where the treated water that passes through the reaction filter (40) stays for a certain period of time so that the ozone remaining the treated water is subjected to a reaction to be reduced to dissolved oxygen; an activated carbon filter (60) that decomposes and filters the ozone remaining in the treated water which passes through the reservoir tank (50); a storage tank (70) where the treated water which passes through the activated carbon filter (60) is stored; a precision filter (80) where the treated water that is stored in the storage tank (70) is selectively supplied by a pump (P1) so that fine foreign substances are removed; and a reverse osmosis membrane filter (90) that passes the treated water which passes through the precision filter (80) through a reverse osmosis membrane at a high pressure by a high-pressure pump (P2) so that the water is separated and discharged by application. According to the present invention having the configuration described above, drinking water and cooling water used in ships can be supplied self-sufficiently by using seawater.
Abstract:
PURPOSE: A lipolysis removal apparatus is provided to be able to prevent the river water and marine pollution and to reduce the processing load of a sewage treatment plant as the fatty acid included in sewage/wastewater is continuously, rapidly and conveniently decomposed and removed. CONSTITUTION: A lipolysis removal apparatus comprises a lipolysis removal tub (120); a hydroxyl radical feeding means (130); and a control box (140). A lipolysis removal tub is partitioned to have an aeration tub (120b) inside. The hydroxyl radical feeding means generates and aerates a large amount of hydroxyl radical with ozone to the aeration tub to decompose the fatty acid in the wastewater with oxidation. The hydroxyl radical feeding means is composed of an air generating unit (131), an ozone generating unit (132) and at least one hydroxyl radical generating unit (133).
