Description

고도처리장치용 여과기{Sand filter for advanced wastewater treatment apparatus}Sand filter for advanced wastewater treatment apparatus

본 발명은 고도처리장치용 여과기에 관한 것으로서, 보다 상세하게는 원수공급관과 고도처리장치의 원수유입관 사이에 위치되어 일정간격으로 회동되면서 원통형상의 필터여과폼을 교체시킴으로써 필터여과폼의 오염여부를 시각적으로 확인할 수 있고, 이에 오염도가 높을 경우 손쉽게 필터여과폼을 교환할 수 있어 원수에 혼합된 슬러지 등의 이물질로부터 상기 원수유입관 유입홀의 막힘을 방지할 수 있는 고도처리장치용 여과기에 관한 것이다. The present invention relates to a filter for an advanced processing apparatus, and more particularly, it is located between the raw water supply pipe and the raw water inlet pipe of the advanced processing apparatus, and rotated at a predetermined interval, thereby replacing the filter filtration foam by replacing the cylindrical filter filtration foam. The present invention relates to a filter for an advanced processing apparatus, which can be visually confirmed, and when the degree of contamination is high, the filter filtration foam can be easily exchanged to prevent clogging of the raw water inlet pipe from foreign substances such as sludge mixed in raw water.

일반적으로 고도처리장치에 이용되는 여과기로는 모래를 이용한 사여과기가 많이 이용되고 있고, 이들은 원수(처리수)의 유입형태에 따라 상향류식과 하향류식으로 구분되며, 처리속도에 따라 급속식과 완속식으로 구분된다.In general, as a filter used in an advanced treatment apparatus, a sand filter is used.They are classified into an upflow type and a downflow type according to the inflow type of raw water (treated water). Separated by.

상기와 같이 구분된 사여과기는, 여과가 진행되는 동안 슬러지가 모래공극 사이에 끼게 됨에 따라, 청소를 위하여 주기적으로 역세척을 해야 하는 등 단점을 내포하고 있으며, 이럴 경우 고도처리장치의 가동을 중지해야 하는 결정적인 단점이 있다.As described above, the filter is classified as having sludge stuck between the sand pores during the filtration process, and thus has a disadvantage of having to periodically backwash for cleaning, in which case the operation of the advanced processing device is stopped. There is a decisive disadvantage to be made.

또한 역세척에 따른 모래의 침식이나 여과층의 혼합 등에 의해 주기적으로 여재를 갈아주어야 하는 등 여러 가지 단점을 내포하고 있다.In addition, there are various disadvantages, such as the need to periodically change the media by erosion of sand or mixing of the filter layer due to backwashing.

한편, 여과조의 가장 큰 목적은 여과 지속시간을 길게 유지한 채 여과수질을 향상시키데 있다.On the other hand, the biggest purpose of the filtration tank is to improve the filtration water quality while maintaining a long filtration duration.

상기 여과 지속시간에 영향을 미치는 중요한 인자는 플록(floc)의 크기와 밀도이다. 플록의 밀도나 강도가 클 경우 여과조에서의 제거효율은 크게 증대될 뿐만 아니라 탁질이 누출될 염려가 적다. 플록의 크기는 여재의 평균 공극크기(100㎛ 전후) 보다 작은 10∼20㎛ 정도가 좋고, 플록의 크기가 여재의 공극보다 더 클 경우 표면여과에 의하여 여재 표면에서 손실수두가 급격하게 증가하게 된다. 50∼300㎛ 크기의 규조류가 발생할 경우 여과지속시간이 급격하게 감소하는 것은 여재의 표면에서 걸름 작용에 의하여 규조류가 제거되기 때문이다.An important factor influencing the duration of the filtration is the size and density of the floc. If the floc density or strength is large, the removal efficiency in the filtration tank is greatly increased and there is little risk of leakage of turbidity. The size of the floc is about 10 to 20 µm, which is smaller than the median pore size (around 100 µm). If the floc is larger than the median pore size, the head of the floc increases rapidly due to surface filtration. . The rapid reduction of the filtration duration when diatoms of 50 to 300 μm occurs is because diatoms are removed by the filtering action from the surface of the media.

여과효율에 영향을 미치는 수질상의 인자는 수온을 비롯한 입자의 크기와 밀도이며, 여과공정의 선택은 원수의 수질에 따라 다르게 결정할 수 있다.The water quality factors affecting the filtration efficiency are the size and density of the particles, including the water temperature, and the choice of filtration process can be determined differently depending on the quality of the raw water.

특히 최근 문제가 되고 있는 바이러스나 Guardia와 같은 10㎛ 이하의 작은 미생물을 제거하는 것이 주 목적이 되는 경우에는 여재의 깊이를 깊게 하고 여재의 입경을 작게 하는 것이 유리한 반면 탁질을 제거하기 위한 급속여과 공정에서는 여상의 표층에서 대부분의 입자가 제거되는 표면여과 현상이 발생하기 때문에 여재 입자를 크게 하고 여상을 깊게 설계하는 것이 바람직하다. 위의 두 가지 문제가 동시에 발생 될 우려가 있는 여과조에서는 최근 2중 외재를 사용하고 있는 추세이다.In particular, if the main purpose is to remove small microorganisms of less than 10 ㎛, such as viruses or Guardia, which are a problem recently, it is advantageous to deepen the depth of the media and to reduce the particle size of the media. In the case of the surface filtration phenomenon in which most particles are removed from the surface layer of the filter bed, it is preferable to increase the filter material particles and design the filter bed deeply. In the filtration tank, which can cause the above two problems at the same time, the trend is to use double external materials.

그러나 탁도의 변화가 심하고 강우에 의해 고탁도 유입이 잦은 정수장에서는 여과조 전에 응집침전 공정을 도입하여 대부분의 입자를 침전지에서 제거하고, 잘 침전되지 않은 일정한 크기의 탁질을 여과조에서 제거하는 것이 바람직하다.However, in a water purification plant where the change in turbidity is severe and frequent high turbidity inflow due to rainfall, it is preferable to introduce a coagulation sedimentation process before the filtration tank to remove most of the particles from the sedimentation basin and to remove the turbidity of a certain size from the filtration tank.

그러나 이때에도 잘 침전되지 않은 규조류가 다량 유입할 경우 여과조의 폐색문제가 자주 발생하게 된다.However, even at this time, if a large amount of diatoms that are not well settled, a problem of occlusion of the filtration tank often occurs.

이에 조류가 많이 발생하는 취수원을 이용하는 정수장에서는 이중여재를 많이 사용하고 있으나 상기 원인으로 인한 여과지 폐색으로 역세척을 자주 시행하여야 하는 번거로움이 발생되고 있다.In the water purification plant using a water source that generates a lot of algae, double media is used a lot, but the hassle of frequent backwashing due to the blockage of the filter paper due to the above-mentioned causes has occurred.

상기와 같은 문제점을 방지하기 위한 종래의 기술로서, 여재의 교환을 방지하고, 여재층의 혼합을 예방하여, 지속적인 여과작용을 수행하기 위한 장치로서 수처리 분야의 고도처리장치의 공정기술 중 하나인 사여과장치가 있다.As a conventional technology for preventing the above problems, it is to prevent the exchange of the filter media, prevent the mixing of the filter media layer, as a device for performing a continuous filtration action, which is one of the process technology of the advanced treatment apparatus in the water treatment field There is a filtering device.

즉, 종래의 급속식 모래여과장치와 완속식 모래여과장치의 장점을 모두 살려서 전술한 종래의 문제점을 해결하기 위하여 발명된 것으로서, 여재층이 수직으로 설치되어 있어 부유물질의 여재입자 사이의 침투가 방지되고, 처리속도가 빨라서 다량의 처리대상 원수를 빠른 시간 내에 처리할 수가 있으며, 기존 모래여과조의 단점인 슬러지의 조기폐색과 여재층의 혼합을 방지하여 역세척 빈도를 감소시킨 고도처리장치용 여과기가 있다.That is, invented to solve the above-mentioned problems by utilizing all the advantages of the conventional rapid sand filter and the slow sand filter, the filter layer is installed vertically, so that the penetration between the filter media particles is suspended. It is prevented, and the processing speed is high, so that a large amount of raw water can be treated in a short time, and it is a filter for an advanced processing apparatus that reduces the frequency of backwashing by preventing premature blockage of sludge and mixing of the filter bed, which are disadvantages of the existing sand filtration tank. There is.

상기와 같이 구성되어 작용하는 종래의 고도처리장치용 여과기는, 여과층이 기존의 수평적치방법에서 수직적치방법으로 대체되어 구성됨에 따라, 여과사의 적치양를 절감시킬 수 있었고, 여과속도 또한 기존 방식보다 빠르게 진행시킬 수 있었으며, 기존 사여과 방식보다 역세척 빈도를 획기적으로 절감시킬 수 있었다.The conventional filter for the advanced processing apparatus configured and acting as described above, as the filtration layer is configured to be replaced by a vertical stacking method from a conventional horizontal stacking method, was able to reduce the amount of piles of the filtrate, and the filtration speed is also higher than that of the conventional method. It was able to proceed quickly and drastically reduced the backwash frequency than the existing filtration method.

그러나, 종래의 고도처리장치용 여과기에 있어서, 원통형 몸체의 내부 중앙에 설치되는 원수 유입관의 홀이 슬러지 등의 이물질에 의하여 자주 막히는 문제점이 있었고, 이로 인하여 원수가 원활히 공급되지 못하는 문제점이 있었으며, 이로 인해 상기 원수 유입관을 수시로 청소해야만 함에 따라 이로 인한 정비시간 및 비용이 많이 소요되는 문제점이 있었다.However, in the conventional filter for advanced processing apparatus, there was a problem that the hole of the raw water inlet pipe installed in the inner center of the cylindrical body was frequently blocked by foreign substances such as sludge, and thus there was a problem that the raw water could not be supplied smoothly. For this reason, since the raw water inlet pipe has to be cleaned from time to time, there is a problem in that it takes a lot of maintenance time and costs.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 원수공급관과 고도처리장치의 원수유입관 사이에 위치되어 일정간격으로 회동되면서 원통형상의 필터여과폼을 교체시킴으로써 필터여과폼의 오염여부를 시각적으로 확인할 수 있고, 이에 오염도가 높을 경우 손쉽게 필터여과폼을 교환할 수 있어 원수에 혼합된 슬러지 등의 이물질로부터 상기 원수유입관 유입홀의 막힘을 방지할 수 있는 고도처리장치용 여과기를 제공함에 그 목적이 있다.The present invention is to solve the above problems, it is located between the raw water supply pipe and the raw water inlet pipe of the advanced processing apparatus is rotated at regular intervals to visually check the contamination of the filter filtration foam by replacing the cylindrical filter filtration foam And, if the contamination is high, the filter filtration foam can be easily exchanged to provide a filter for the advanced processing apparatus that can prevent the blockage of the inlet of the raw water inlet pipe from foreign substances such as sludge mixed in the raw water. .
