Description

막분리형 상수의 취수, 정수처리 시스템{A System For Water Treatment Used Immersed Type Membrane}A System For Water Treatment Used Immersed Type Membrane

본 발명은 막분리형 상수의 취수, 정수처리 시스템에 관한 것으로, 더 상세하게는 막분리 수처리 장치를 상수원 상에 침지하고, 이 침지된 막분리 수처리 장치를 통하여 상수를 취수와 동시에 정수처리 하는 시스템에 관한 것이다.The present invention relates to a water intake and water purification system for membrane separation constant, and more particularly, to a system for immersing a membrane separation water treatment device on a water source and simultaneously purifying water through the immersion membrane separation water treatment device. It is about.

통상, 식수의 상수원은 저수지 또는 댐등에 저수된 담수를 많이 사용하고 있고, 이 담수의 취수는 취수탑을 이용하고 있는바, 예를들면 저수지의 일정한 장소에 일정한 높이를 갖은 취수탑을 고정 설치하고, 이 취수탑의 높이를 따라 일정간격으로 제1취수구, 제2취수구 등 다단으로 취수구를 설치하여 수위의 변화 높이에 따라 선택적으로 해당 취수구의 밸브를 열어 취수되도록 하고 있었다.In general, the drinking water source uses a lot of fresh water stored in a reservoir or a dam, and the intake of the fresh water uses a water intake tower, for example, a fixed water intake tower having a fixed height is installed at a fixed place of the reservoir. The inlet was installed in multiple stages such as the first inlet and the second inlet at regular intervals along the height of the intake tower to selectively open the intake valves according to the height of the water level.

이러한 취수과정에서 식수원의 상급수는 수위표면으로 부터 약 1~2m 이내의 물, 즉 담수의 수표면에는 부유물들이 떠다니고, 바닥부에는 침전물들이 많아 식수원으로는 적합하지 못하여, 상기 수표면으로 부터 2m 정도의 물을 상수원으로 취수 하는 것이 바람직하다.In this water intake process, the upper water of the drinking water source is less than 1 ~ 2m from the water surface, that is, floating water is floating on the water surface of fresh water, and there are many sediment at the bottom, so it is not suitable as a drinking water source. It is preferable to take about 2m of water as a water source.

그런데, 상기와 같은 취수탑의 취수 방식은 담수량의 수표면 가변성에 능동적인 대처가 안되고, 이의 관리도 용이하지 못한 문제점이 있었다.However, the intake method of the intake tower as described above does not have an active response to the water surface variability of fresh water, there was a problem that its management is not easy.

이와 같은 문제점을 해결하기 위한 것으로, 상수원 취수구에 부구를 이용하고, 부구로 부터 약 2m 아래에 취수 입구가 위치되도록 한 것이 있으나, 이 또한 부구의 수표이동이나, 이물질의 이동에 저해요인이 되어 문제점이 있었다.In order to solve such a problem, the use of a float in the water supply intake, and the intake inlet is located about 2m below the float, but this is also a problem to hinder the movement of the check, or the movement of foreign matter. There was this.

또한, 상기와 같이 취수된 물을 식수로 이용하기 위하여, 정수함에 있어, 넓은 정수장을 이용하여 응집, 침전공정, 여과공정, 정화공정 및 살균처리공정 등으로 이루어져 있다. 이와같이 넓은 면적을 이용하고, 복잡한 공정을 거치면서도 식수의 수질기준에 미치지 못하는 경우가 반복되고 있고, 이로 인하여 수도물에 대한 국민적 불신이 팽배되어 있다.In addition, in order to use the water withdrawal as described above, in the purified water, it is composed of a coagulation, sedimentation process, filtration process, purification process and sterilization process using a wide water purification plant. As such, the use of such a large area and a complicated process have repeatedly failed to meet the water quality standards of drinking water, and this has led to the distrust of national water.

특히, 생활수준의 향상과 산업의 고도화에 따라 각종 오염원이 발생되어 상수원으로 흘러 들어가 오염시켜 수질이 악화되는바, 이와 같이 악화된 수질의 물을 취수하여 정수처리 하는 것은 한계가 있어, 식수에 대한 불안감이 있는 것이다.In particular, with the improvement of living standards and the advancement of the industry, various pollutants are generated and flow into the water supply to contaminate the water quality, which deteriorates the water quality. There is anxiety.

본 발명은 이상과 같은 문제점들을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 저수지에서 담수의 식수를 취수함에 있어, 막분리로 자연여과 혹은 흡입여과되는 유니트를 상기 저수지상에 장치하고, 이를 통하여 중력분리, 정압분리 등으로 취수하여 정수처리 되는 시스템을 제공함에 있다.The present invention has been made in order to solve the above problems, an object of the present invention is to collect the drinking water of fresh water in the reservoir, the unit which is natural filtration or suction filtration by membrane separation on the reservoir, through It is to provide a system that is purified by gravity separation, static pressure separation, etc.

본 발명의 다른 목적은 막분리 여과기술과 설비의 단순화 및 자동화 등으로 유지관리의 편리성을 획기적으로 개선한 식수의 취수, 정수처리 시스템을 제공함에 있다.It is another object of the present invention to provide a drinking water intake and water treatment system that dramatically improves the convenience of maintenance by membrane separation filtration technology and equipment simplification and automation.
