Description

스크린 및 소독 산화장치를 구비한 병원폐수 처리 시스템{Hospital sewage disposal system}Hospital wastewater treatment system equipped with screen and disinfection oxidizer {Hospital sewage disposal system}

본 발명은 스크린 및 소독 산화장치를 구비한 병원폐수 처리 시스템에 관한 것으로서, 더욱 구체적으로는 폐수를 본격적으로 처리하는 주처리공정 이전에 폐수에 포함된 협잡물을 제거하도록 전처리 공정을 구성하고, 주처리공정 이후에 처리수의 살균을 위해 UV램프를 이용한 후처리 공정을 구성하여, 친환경적인 폐수처리가 가능한 스크린 및 소독 산화장치를 구비한 병원폐수 처리 시스템에 관한 기술이다.The present invention relates to a hospital wastewater treatment system having a screen and a disinfection and oxidizing device, and more specifically, a pretreatment process is configured to remove contaminants contained in wastewater before the main treatment process of treating wastewater in earnest, and the main treatment It is a technology related to a hospital wastewater treatment system equipped with a screen and a disinfection oxidizer capable of eco-friendly wastewater treatment by configuring a post-treatment process using a UV lamp to sterilize the treated water after the process.

일반적으로 병원에서 배출되는 폐수는 의료시설로부터 유출되는 액상의 오염물질이 혼합된 것으로써 주로 부유물질, 유무기물질, 질소 및 인 등의 영양염류, 기타 병원성 박테리아, 유해화학물질 등의 성분을 포함하고 있다.In general, wastewater discharged from hospitals is a mixture of liquid contaminants discharged from medical facilities, and mainly contains components such as suspended solids, organic/inorganic substances, nutrients such as nitrogen and phosphorus, other pathogenic bacteria, and harmful chemicals. are doing

상기 오염물질 중에서 질소와 인이 제거되지 않은 폐수가 하천으로 유입되는 경우, 하천의 부영양화로 인한 적조 또는 녹조현상이 발생되어 하천 내의 용존산소량을 저감시켜 수중의 생태계가 파괴될 우려가 있으며, 나아가 상수도원을 오염시킬 수 있다. When wastewater from which nitrogen and phosphorus are not removed from among the pollutants flows into a river, red tide or green algae phenomenon occurs due to eutrophication of the river, reducing the amount of dissolved oxygen in the river, and there is a risk that the underwater ecosystem may be destroyed, furthermore, there is a risk that the water supply system It can contaminate the circle.

그리고 이러한 병원폐수는 멸균 특성상 병원에서 사용되는 소독제는 주로 염소화합물로써 생물학적처리 공정에서 방해요소로 작용하며, 방사선 촬영 중에 생성되는 수은, 납, 카드뮴 및 기타 중금속은 환경에 부정적인 결과를 가져옴으로써 처리에 많은 어려움을 초래하게 된다.In addition, due to the sterilization characteristics of these hospital wastewater, disinfectants used in hospitals are mainly chlorine compounds, which act as interfering factors in the biological treatment process. will cause many difficulties.

또한 병원폐수 및 의료시설의 특징은 감염성 질병, 결핵, 병원균 박테리아 존재하며, 병원성 박테리아로 오염된 폐수로 인해 콜레라, 장티푸스, 살모넬라, 이질, 브루셀라증, 결핵, 탄저병, 결핵, 간 질환, 장 바이러스 감염 및 기타 질병 등이 사람과 동물에게 2차 감염을 유발하게 된다.In addition, the characteristics of hospital wastewater and medical facilities include the presence of infectious diseases, tuberculosis, and pathogenic bacteria, and cholera, typhoid, salmonella, dysentery, brucellosis, tuberculosis, anthrax, tuberculosis, liver disease, enterovirus infection and Other diseases cause secondary infection in humans and animals.

이러한 폐수처리는 국내뿐만 아니라 개발도상국(베트남, 태국, 라오스, 캄보디아 등)에 더 필요로 하는 실정이다. 대부분의 개발도상국에서 발생하는 고질적인 환경문제인 수질오염 문제는 급속한 경제발전으로 도시의 인구가 팽창하고 산업시설이 많이 생기는 반면, 하수 및 하천의 심각한 오염은 등한시하는 수질 환경에 대한 인식 부족과 수처리 관련 낮은 기술 수준에 기인하고 있다.Such wastewater treatment is needed not only in Korea but also in developing countries (Vietnam, Thailand, Laos, Cambodia, etc.). The problem of water pollution, a chronic environmental problem that occurs in most developing countries, is a lack of awareness of the water quality environment, which neglects serious pollution of sewage and rivers, while urban population expands and industrial facilities are created due to rapid economic development. This is due to the low level of technology.

특히, 베트남은 최근 연평균 7%의 경제성장(GDP 65%를 소비)으로 산업화, 도시화가 빠르게 진행되었으며, 도농인구의 성장과 많은 산업 지역의 개발로 수질오염이 심각한 문제에 도달하여, 전체 도시인구의 절반(750만명)만이 생활용수를 상수관을 통해 생활용수를 공급받고 있을 정도로 수계의 자연 정수능력의 저하와 도시화, 공업화에 따른 수질오염이 심각하다.In particular, Vietnam has recently undergone rapid industrialization and urbanization with an average annual economic growth of 7% (consumption of 65% of GDP). Only half of the country (7.5 million people) are receiving water for daily use through water pipes, so the natural water purification capacity of the water system is declining and water pollution is serious due to urbanization and industrialization.

상기 UV소독장치(620)는 도 3 내지 4에 도시한 바와 같이 원통형의 형상으로 이루어지며 상부에 소독대상에 해당하는 폐수가 공급되는 유입부(621-1) 및 살균처리된 정화수를 배출하는 배출부(621-2)가 형성되는 본체부(621)와, 상기 본체부(621)에 형성되어 살균에 필요한 약품이 공급되도록 한 약품공급부(622)와, 상기 본체부(621)의 중앙에 길이방향으로 수평 설치되는 UV램프(623)와, 상기 UV램프(623)의 하부에 설치되어 오존(O3) 기포를 발생시키는 기포발생부(624)와, 상기 UV램프(623)의 상부에 설치되어 기포발생부(624)에서 상승한 기포가 UV램프(623) 주변으로 체류되도록 한 차단판(625);으로 구성되는 것을 특징으로 한다.The UV disinfection device 620 has a cylindrical shape, as shown in FIGS. 3 to 4 , an inlet 621-1 to which wastewater corresponding to a disinfection target is supplied, and an exhaust for discharging sterilized purified water. The main body portion 621 in which the portion 621-2 is formed, the chemical supply portion 622 formed in the main body portion 621 to supply chemicals necessary for sterilization, and a length in the center of the main body portion 621 A UV lamp 623 installed horizontally in the direction, a bubble generating unit 624 installed under the UV lamp 623 to generate ozone (O 3 ) bubbles, and the UV lamp 623 installed on the upper part It is characterized in that it is composed of a; blocking plate 625 so that the bubbles rising from the bubble generating unit 624 stay around the UV lamp 623 .

상기 본체부(621)는 상부에 유입부(621-1)와 배출부(621-2)가 형성되어 있어, 유입부(621-1)를 통해 본체부(621)에 폐수가 채워지고 살균처리가 된 정화수는 배출부(621-2)를 통해 외부로 배출되게 된다. 그리고 상기 본체부(621)의 일측에는 살균에 필요한 약품이 공급되는 약품공급부(622)가 형성되어 있다. 이때 상기 약품공급부(622)는 산화처리에 필요한 약품이 공급될 수 있으며, 하나의 예로 과산화수소가 투입될 수 있다.The main body 621 has an inlet 621-1 and an outlet 621-2 formed thereon, so that wastewater is filled in the main body 621 through the inlet 621-1 and sterilized. The purified water is discharged to the outside through the discharge unit 621-2. And on one side of the main body portion 621 is formed a chemical supply unit 622 to which the chemical necessary for sterilization is supplied. In this case, the chemical supply unit 622 may supply a chemical necessary for oxidation treatment, and hydrogen peroxide may be injected as an example.

종래의 UV살균방식은 수조의 덮개부분에 설치되어 수조에 채워진 물로 자외선을 조사하는 방식으로 되어 있는데, 이러한 방식은 자외선이 물의 상부에만 조사되기 때문에, 살균효과가 떨어지는 문제점이 있었다. The conventional UV sterilization method is installed on the cover of the water tank and irradiating UV rays with water filled in the water tank.

따라서, 본 발명의 UV램프(623)는 본체부(621)의 길이방향 수평으로 중앙에 설치됨으로써, UV램프(623)가 폐수에 잠긴 형태가 된다. 그로 인해 UV램프(623)에서 발생되는 자외선은 360°방향의 폐수에 전달되어 살균효율을 더욱 높일 수 있다. 상기 UV램프(623)는 램프 그대로 삽입될 수 있지만, 램프의 교환문제 및 폐수와의 접촉을 방지하기 위해 UV램프(623)의 외측으로 투명커버(623a)를 더 구성하는 것이 좋다.Therefore, the UV lamp 623 of the present invention is installed in the center horizontally in the longitudinal direction of the body portion 621, so that the UV lamp 623 is submerged in wastewater. Therefore, the ultraviolet rays generated from the UV lamp 623 are transmitted to the wastewater in the 360° direction, thereby further increasing the sterilization efficiency. The UV lamp 623 can be inserted as it is, but it is preferable to further configure a transparent cover 623a outside the UV lamp 623 to prevent the lamp replacement problem and contact with wastewater.

상기 기포발생부(624)는 UV램프(623)의 하부에 설치되어 오존(O3) 기포를 발생시키는 것으로서, 기포가 토출되는 통공부(624-1)가 형성되어 있다. 상기 기포발생부(624)의 바람직한 실시예는 도 5에 도시한 바와 같이 UV램프(623)의 원호상에 일정한 반경에 복수로 배치되는 것에 있다. 즉, UV램프(623)주변으로 오존(O3) 기포를 발생시켜 오존의 살균효과와 UV램프(623)의 살균효과의 시너지를 향상시킬 수 있고, 발생된 기포가 UV램프(623)에 부딪히면서 기포발생을 좀 더 촉진시키고 체류시간을 늘려 살균효과가 지속되도록 한다. The bubble generating part 624 is installed under the UV lamp 623 to generate ozone (O 3 ) bubbles, and a through part 624-1 through which the bubbles are discharged is formed. A preferred embodiment of the bubble generating unit 624 is that as shown in FIG. 5, a plurality of UV lamps 623 are arranged at a certain radius on the arc. That is, ozone (O 3 ) bubbles are generated around the UV lamp 623 to improve the synergy between the sterilization effect of ozone and the sterilization effect of the UV lamp 623 , and the generated bubbles collide with the UV lamp 623 . It promotes the generation of bubbles and increases the residence time so that the sterilization effect is continued.

That is, the sterilization effect is further enhanced by inducing the ozone bubbles to remain in the wastewater without rising immediately. As shown in the drawing, the preferred shape of the blocking plate 625 is preferably formed in a semicircular arc shape centered on the UV lamp 623. The bubble generating unit 624 is an arc of the blocking plate 625. It is arranged so as to be within the range of the virtual circle along the , thereby further improving the synergy between the sterilization effect of ozone and the sterilization effect of the UV lamp 623, and the bubbles rising from the bubble generating unit 624 are generated by the UV lamp 623. You can effectively stay around more.

아울러, 상기 차단판(625)의 내측에는 반사층(625-1)이 코팅되어 있을 경우, UV램프(623)에서 발생된 자외선이 반사층(625-1)에 반사되어 다시 하부로 조사됨으로써, 살균효과를 더욱 높일 수 있게 된다.In addition, when the reflective layer 625-1 is coated on the inside of the blocking plate 625, the ultraviolet rays generated from the UV lamp 623 are reflected by the reflective layer 625-1 and irradiated to the lower side, thereby sterilizing effect. can be further increased.

상기 차단판(625)의 중앙에는 공기배출구(625-2)멍이 형성되어, 차단판(625) 내측으로 공기층이 형성되지 않도록 한다. 상기 공기배출구(625-2)멍은 차단판(625)의 길이방향으로 복수 형성될 수 있다.An air outlet 625-2 hole is formed in the center of the blocking plate 625 to prevent an air layer from being formed inside the blocking plate 625. A plurality of holes for the air outlet 625 - 2 may be formed in the longitudinal direction of the blocking plate 625 .

이와 같이 본 발명의 UV소독장치(620)는 UV램프(623)와 오존(O3) 기포를 통해 살균이 이루어지기 때문에, 기존의 소독장치에 사용되었던 염소 소독에 따른 약품비를 크게 줄일 수 있고, 내염소성 미생물을 비롯한 소독효과가 극대화되는 이점이 있다.As described above, since the UV disinfection device 620 of the present invention is sterilized through the UV lamp 623 and ozone (O 3 ) bubbles, the chemical cost due to chlorine disinfection used in the existing disinfection device can be greatly reduced, There is an advantage in that the disinfection effect including chlorine-resistant microorganisms is maximized.

이상에서 본 발명은 상기 실시예를 참고하여 설명하였지만 본 발명의 기술사상범위 내에서 다양한 변형실시가 가능함은 물론이다.Although the present invention has been described above with reference to the above embodiments, it goes without saying that various modifications are possible within the scope of the technical spirit of the present invention.
