Abstract

본 고안은 집단급수시설 간이상수도에 대한 지하수 및 계곡수나 하천수등 용천수에서 흘러나오는 자연수를 맑고 깨끗한 물로 정화시켜 주민들에게 공급코자 상수도용 간이급속여과침전시설을 반 영구적으로 사용할 수 있도록 만든 장치에 관한 것이다.The present invention relates to a device that makes it possible to semi-permanently use a simple rapid filtration and sedimentation facility for tap water to supply residents by purifying the groundwater and the natural water flowing from spring water such as valley water or river water for group water supply facilities. .

본 고안은 지방상수도 보급이 어려운 농어촌 산간도서 지역에 주로 설치되어 있는 간이상수도 시설이 노후화 되거나 여과시설이 전혀없어 무방비 상태로 배수지로 흘러들어와 식수로 사용하고 있는 실정입니다. 산에서 흘러내려오는 자연수속에는 산간지역 농작물 경작으로 인한 농약사용 유실수로 인한 항공방제등으로 수질이 악화 될 뿐아니라 갈수기나 우수기시 흙탕물로 인한 탁도 및 부유물질이 상승하고 취수원 부근에 환경오염, 수질오염,대기오염으로 인하여 바이러스 및 세균성이질 등 식수에 해로운 세균이 발생할 우려가 매우 높습니다.The present invention is a situation where water and wastewater facilities, which are mainly installed in mountainous islands in rural areas where it is difficult to spread local waterworks, are aging or have no filtering facilities. The natural water flowing down from the mountains is not only deteriorated due to air pollution due to the loss of pesticide use due to the cultivation of agricultural products in the mountains, but also turbidity and suspended solids from the dry season or muddy water during the rainy season, and the environmental pollution and water pollution near the water intake. Air pollution is very likely to cause harmful bacteria such as viruses and bacterial dysentery.

환절기에는 유해물질, 동·식물유충알, 물벼룩, 뱀, 개구리 등 조류가 발생하며 모래, 자갈등이 배수지 내부에 스며들어 수질이 악화되어 송배수관이 막힘으로써 급수불량 사례가 자주 발생 합니다. 그 뿐만 아니라 수질기준에 부적합 됨으로써 농·어촌 주민들에게 식수공급에 많은 차질을 가져다 줍니다. 갈수기시기에도 이와같은 현상이 빚어짐으로써 본 고안자는 맑고 깨끗한 물을 안정적으로 주민들에게 공급하는데 목적이 있다.During the season, algae such as harmful substances, animal and plant larvae, water fleas, snakes, frogs, etc. occur, and sand, gravel, etc. penetrate into the drainage, causing deterioration in water quality, causing frequent drainage. Not only that, it does not meet the water quality standards, which brings many obstacles to the supply of drinking water. This phenomenon occurs even during the dry season, and the inventors aim to provide the residents with clean and stable water.

본 고안자는 농·어촌 간이상수도시설이 과거에는 자갈이나 모래만을 이용완속여과 시설을 사용한 결과 단기간에 관로가 막히고 여과기능이 마비되어 쓸데없는 예산만 낭비하게 하였습니다.The inventors of the farm and fishing village water supply facilities in the past used only gravel or sand as a result of the slow filtration system, the pipeline was blocked in a short period of time and the filtration function was paralyzed.

본 간이 급속여과 침전장치는 취수원에서 흘러내려오는 물을 제일 먼저 물을 침전시켜 여과된 물을 다음단계 급속여과시설로 내려 보내는 장치로서 아주 중요한 부분이기도 합니다.This quick filtration settling device is a very important part as it first precipitates the water flowing down from the intake source and sends the filtered water down to the next rapid filtration facility.

간이급속여과침전장치는 낙엽, 부유물질, 동·식물유충알 등 흙탕물, 이끼등을 제거할 뿐 아니라 중금속이 포함된 냄새, 맛, 취미등을 제거 목적으로 3단계 여과처리하는 방식으로 채택토록 하였습니다.The simple rapid filtration and sedimentation system is designed not only to remove fallen leaves, floating materials, mud and other moss such as animal and plant larvae, but also to remove odors, tastes, and hobbies that contain heavy metals. .

저장탱크를 횡으로 설치 오버드레인과 약품투입구 및 유입밸브가 설치되어 있으며 하단에는 폐수슬러지 밸브 및 급속여과기가 배수지로 내려 가도록 유출밸브를 부착시켜 자연유하로 흘러내려 가도록 되어 있다. 따라서 본 고안에 의하면 상수도 간이급속여과 침전장치는 동력비가 없고 유지관리가 쉬울 뿐 만 아니라 역세척도 자동적으로 할 수 있으며 염소소독도 손쉽게 다룰 수 있습니다.Storage tank is installed horizontally. Overdrain, chemical inlet and inlet valve are installed. At the bottom, wastewater sludge valve and outlet filter are attached to the drainage basin to flow down to natural oil. Therefore, according to the present invention, the water supply quick filtration sedimentation device is not only energy-free, easy to maintain, but also can backwash automatically and can handle chlorine disinfection easily.

폐수슬러지는 밸브만 열어주면 자동으로 흘러가게 됨으로써 2중효과를 얻을수가 있음으로 농·어촌 간이상수도시설로 아주 편리한 장치이며 반영구적으로 사용할 수 있습니다.The waste water sludge flows automatically when only the valve is opened, so the double effect can be obtained. It is a very convenient device as an ideal water supply facility between farming and fishing villages and can be used semi-permanently.

Description

상수도용 간이 급속 침전 여과 장치{Simplicty prompt filtration system for water works}Simplicty prompt filtration system for water works

본 고안은 집단 급수시설(간이상수도)에 침전 여과시킬 목적으로 여과탱크내 염소소독설비 및 맥반석 및 바이오사를 주입하여 반영구적으로 안정적인 양질의 식수를 공급하도록 만든 장치이다.The present invention is a device made to supply semi-permanently stable high quality drinking water by injecting chlorine disinfection facility and ganban stone and bio company in the filtration tank for the purpose of sedimentation and filtration in the collective water supply facilities (liver water).

일반적으로 간이상수도 시설을 지방상수도 보급이 어려운 농·어촌 산간도서지역에 설치되어 있는 시설로 주로 시골지역에 위치해 있어 당연히 맑은물이 공급되는 것으로 지금까지는 별 관심없이 소외되어 왔던 시설이다. 그러므로 당연히 간이상수도 시설에 여과시설을 설치하는 것이 미흡할 수 밖에 없는 실정이다.In general, it is a facility installed in the mountainous islands of farming and fishing villages where it is difficult to spread the local water supply system. It is located in the rural area and is naturally supplied with clean water. Therefore, of course, it is inadequate to install a filtration facility in a liver water supply facility.

완속여과시설이라고 설치한 시설에는 자갈이나 모래만을 이용 마구잡이 식으로 콘크리트탱크나 FRP통속에 바로 넣어 설치함으로써 막힘현상, 여과기능마비로 유명무실화되어 버리곤 하였습니다.The facility, which was installed as a slow filtration facility, was installed in a concrete tank or FRP barrel at random by using only gravel or sand, and became famous for clogging and paralysis.

이러한 현상들을 보완하여 새로운 신제품으로 생산, 간이상수도시설에 새로운 시스템을 구축하여 맑은물 공급에 최선을 다 하고자 함Complementing these phenomena, we are trying to do our best to supply clean water by establishing a new system at the new water production facility with new products.

본 상수도용 간이급속침전여과시설은 완벽하게 여과기능이 갖추어져 있습니다.This rapid rapid sedimentation filtration facility for waterworks is fully equipped with filtration.

농약등 항공방제 및 중금속 이미취 및 냄새, 막을 제거하기 위해 왕자갈+맥반석으로 1차여과 처리하고 중자갈+목탄, 숯 등을 사용 2차 여과처리 한 다음 여과사 및 바이오사등 3차여과 처리하는 방식으로 채택 하였습니다.In order to remove odors, odors and membranes from aerosols such as agrochemicals, primary filtration is carried out with wangjagal + ganban rock and secondary filtration with heavy flakes + charcoal and charcoal. Adopted in such a way.

여과층에는 불순물이나 이물질등이 있을 때 자동 역 세척할 수 가 있으며 폐수슬러지 처리는 밸브 하나만 열어주면 됩니다.When there are impurities or foreign substances in the filtration layer, it can be automatically back-washed and wastewater sludge treatment needs only one valve open.

무분별한 지하수 개발로 자연이 훼손되고 수질은 날로 오염될 뿐 아니라, 지하수는 시간이 경과될수록 자연 고갈되어 지하수는 그 양이 부족하여 심각한 실정입니다.In addition to indiscriminate groundwater development, nature is damaged and water quality is contaminated day by day. Groundwater is depleted over time, and groundwater is in short supply.

가급적 계곡수, 용천수, 하천수가 물 수량이 풍부하다면 간이급속여과 침전시설을 설치하여 깨끗하고 맑은 물 공급 대책 일환으로 반영구적으로 사용할 수 있는 침전여과시설장치를 사용하는 것이 경제적으로 큰 이윤을 가져다 줄 것이며, 자연환경을 후손들에게 물려줄 큰 유산이라고 생각합니다.If valley water, spring water, and river water are abundant in quantity, it is economically profitable to use a sediment filtration system that can be used semi-permanently as a part of the provision of a simple rapid filtration sedimentation system to provide clean and clear water supply measures. I think that the natural environment is a great legacy to inherit from the descendants.
