Description

유지관리가 간편한 수처리용 상향류 여과조{Upflow Filtration Tank Convenient for Maintenance}Upflow Filtration Tank Convenient for Maintenance

본 발명은 수처리장치의 여과공정에 사용되는 여과조에 관한 것이다.
The present invention relates to a filtration tank used in the filtration step of the water treatment device.

통상 상수, 하수 또는 폐수 처리과정은 원수중의 부유물질과, 중금속, 미량유기물질, 세균 등의 유해물을 제거하기 위해 온화/응집공정, 약품처리공정, 침전공정, 여과공정, 살균공정 등의 단위공정의 조합으로 구성된다. 이중 여과공정은 침전지에서 침전되지 않은 미세 플록(floc)을 제거하기 위한 것으로, 정수처리과정에서 탁질을 제거하는 공정이다. 도 1에 통상의 상수, 하수 또는 폐수 처리과정을 흐름도로 표시하였다. 여과공정이 수행되는 여과조 또는 여과지에서는 수중의 미립자, 조류 등의 부유물질이 여과재로 충진된 여과층에서 확산(diffusion), 여별효과(straining), 차단(interception), 관성충돌(impaction), 침전(sedimentation), 응집(flocculation) 및 흡착(adsorption) 등과 같은 물리·화학적 단위조작이 상호작용하는 복잡한 메카니즘에 의해 포획·제거되고, 이로써 청정 여과수가 배출된다. 한편, 여과공정에서는 운전 시간이 경과될수록 수중의 입자성 물질이 여과재 내에 축적되어 폐색이 되고, 이에 따른 여과 유속 및 유량의 감소가 자연적으로 발생하기 때문에 주기적인 역세척이 필수적으로 요구된다.
In general, water, sewage, or wastewater treatment processes include mild / aggregate, chemical treatment, precipitation, filtration, and sterilization processes to remove suspended substances in raw water and harmful substances such as heavy metals, trace organic substances, and bacteria. It consists of a combination of processes. The double filtration process is to remove fine flocs that have not settled in the sedimentation basin, and is a process of removing turbidity in the water purification process. 1 is a flow chart of a conventional water treatment, sewage or wastewater treatment process. In the filtration tank or filter paper where the filtration process is carried out, diffusion, straining, interception, inertial collision and precipitation in the filtration layer filled with particulate matter, algae, etc. Physical and chemical unit operations, such as sedimentation, flocculation and adsorption, are captured and removed by a complex mechanism that interacts with each other, resulting in clean filtered water discharge. Meanwhile, in the filtration process, periodic backwashing is essential because the particulate matter in the water accumulates in the filter medium and becomes clogged as the operation time elapses, and thus a decrease in the filtration flow rate and the flow rate occurs naturally.

따라서 여과공정이 효율적으로 이루어지기 위해서는 ① 여과특성이 우수할 것 ② 여과조 또는 여과지(이하 '여과조'라 함)의 크기가 작을 것 ③ 역세척 주기, 역세척에 소비되는 에너지 및 물의 양 등 역세척 특성이 우수할 것 ④ 설비가 간단하고 관리가 용이할 것 등이 요구된다. 현재까지는 이러한 요구사항을 모두 만족하는 장치가 제시된 바 없다.Therefore, in order for the filtration process to be carried out efficiently, the filtration characteristics must be excellent. ② The size of the filtration tank or the filter paper (hereinafter referred to as the 'filtration tank') must be small. ③ The backwash cycle, the backwashing cycle, etc. Excellent characteristics ④ Simple and easy management is required. To date, no device has been proposed that meets all of these requirements.

등록실용 20-0183914에는, 역세척중에 순간순간 고압의 공기를 발사하여 여과사면 또는 표층부에 퇴적된 부유물, 니토 등을 완전히 제거하고 외부의 공기를 표층부에 분사시켜 여과재의 표면 및 여과층의 세척효과를 증대시킨 여과조 세척장치가 개시되어 있다. 그러나 상기 고안은 여과재층 표면만의 세척효과가 커질 뿐 전체 여과재층에 대한 처리효과는 증대되지 않는다.For 20-0183914, the high-temperature air is momentarily fired during backwashing to completely remove suspended solids, nito, etc. deposited on the filtration slope or surface layer and spray external air to the surface layer to wash the surface of the filter medium and the filtration layer. Disclosed is a filtration tank washing apparatus. However, the above design only increases the cleaning effect only on the surface of the filter medium layer, and does not increase the treatment effect on the entire filter medium layer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. However, this is only an example for easily explaining the content and scope of the technical idea of the present invention, whereby the technical scope of the present invention is not limited or changed. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples.

전술하였듯이 본 발명은, 하단부에 내측으로 유입수가 유입되는 유입관(31), 상단부에 여과수가 유출되는 유출관(32), 중간에 여과재층(10)이 형성된 수처리용 상향류 여과조에 관한 것으로서, (A) 상기 여과재층(10)은, ① 상기 여과재층(10)의 하면을 구획하며 복수개의 투수공이 형성된 하지지판(11); ② 상기 여과재층(10)의 상면을 구획하며 복수개의 투수공이 형성된 상지지판(12); 및 ③ 상기 하지지판(11)과 상지지판(12) 사이에 개재되는 다공성의 고탄성 재질의 여과재(13);를 포함하며, (B) 상기 여과재층(10)의 하지지판(11) 또는 상지지판(12)을 상하이동시키는 압착수단(20)을 추가로 포함하는 수처리용 상향류 여과조이다(도 2a 참조). 본 발명에 의한 수처리용 상향류 여과조의 하단부에 내측으로 (역)세척수 배출을 위한 세척수배출관(33)을 둔다.As described above, the present invention relates to an inlet pipe 31 through which inflow water flows into the lower end portion, an outlet pipe 32 through which the filtered water flows out at the upper end portion, and an upflow filtration tank for water treatment in which a filter medium layer 10 is formed. (A) The filter medium layer 10 comprises: (1) a base support plate (11) which partitions a lower surface of the filter medium layer (10) and has a plurality of permeable holes; ② an upper support plate 12 partitioning the upper surface of the filter medium layer 10 and having a plurality of water permeable holes; And (3) a porous filter material of porous high elasticity material interposed between the base support plate 11 and the upper support plate 12, and (B) the base support plate 11 or the upper support plate of the filter medium layer 10. It is an upflow filtration tank for water treatment, which further includes a crimping means (20) for moving (12). A washing water discharge pipe (33) for discharging (reverse) washing water is placed in the lower end of the upstream filtration tank for water treatment according to the present invention.

본 발명은 다공성의 고탄성 재질의 여과재(13)를 적용하며, 세척시 이를 압착하여 여과재(13)에 흡착된 이물질을 강제적으로 탈락시키도록 하는 것을 기본 개념으로 한다. 따라서 본 발명에서 상기 여과재(13)는 투수공이 형성된 하지지판(11) 및 상지지판(12) 사이에 포획되어 있으며, 하지지판(11)과 상지지판(12)의 어느 하나 또는 둘 모두 상하로 이동가능한 구조로 되어 있으며, 상기 압착수단(20)이 하지지판(11) 또는 상지지판(12)이 상하이동되도록 하는 동력을 부여한다. 본 발명에서 상기 압착수단(20)은 유압실린더와 유압모터 세트이거나, 전동모터와 스크루축 세트일 수 있으나 이에 한정되는 것은 아니며, 이러한 압착수단(20)은 당업자에게 있어 용이하게 선택할 수 있는 것이므로 구체적인 설명이나 도면의 도시를 생략한다.The present invention is applied to the porous filter material 13 of high elasticity, it is a basic concept to be forced to drop off the foreign matter adsorbed on the filter medium 13 by pressing it when washing. Therefore, in the present invention, the filter medium 13 is trapped between the base support plate 11 and the upper support plate 12 formed with a perforation hole, and any one or both of the base support plate 11 and the upper support plate 12 is moved up and down. The structure is possible, the pressing means 20 is applied to the base plate 11 or the upper support plate 12 to power the shank. In the present invention, the crimping means 20 may be a hydraulic cylinder and a hydraulic motor set, or an electric motor and a screw shaft set, but is not limited thereto, and the crimping means 20 may be easily selected by those skilled in the art. Description and illustration of the drawings will be omitted.

본 발명에 의한 상향류 여과조를 운용하다가 여과재층(10)을 세척할 필요가 있으면, 통상의 여과조와는 달리 반드시 '역세척'할 필요가 없다. 예를 들면, 여과재층(10)이 잠길 정도로 세척수를 도입시킨 다음 여과재층(10)을 반복적으로 압착-압착해제한다. 도 2b에 본 발명에 의한 상향류 여과조에서 여과재층(10)이 압착수단(20)에 의해 상지지판(12)과 하지지판(11) 사이의 간격이 좁아지면서 여과재(13)가 압착된 상태를 도시하였다. 반복적인 압착-압착해제에 의해 여과재(13)는 마치 빨래가 되듯이, 압착될 때 이물질이 '짜여'지면서 여과재층(10)에서 탈락되고 압착해제될 때 세척수가 여과재(13)에 흡수되고, 다시 압착되면 잔류된 이물질이 '짜여'지면서 또 탈락되고.... 하는 과정을 통해 빠르고 효과적으로 제거된다. 여과재층(10)에 남아있는 이물질의 농도와 세척수중으로 탈락된 이물질의 농도가 비슷해 지면 여과재층(10)을 짜면서 세척수를 교환한 다음 위 과정을 반복하게 된다. 물론 이 과정에서 역세척이 동시에 이루어질 수도 있다. 역세척을 고려하는 경우, 상부에 역세용급수관(34)을 설치한다.
If it is necessary to wash the filter medium layer 10 while operating the upflow filtration tank according to the present invention, it is not necessarily 'backwashed' unlike a conventional filtration tank. For example, washing water is introduced to the extent that the filter media layer 10 is submerged, and then the filter media layer 10 is repeatedly press-decompressed. 2B shows a state in which the filter medium 13 is compressed while the filter medium layer 10 is narrowed by the pressing means 20 between the upper support plate 12 and the base support plate 11 in the upflow filter tank according to the present invention. Shown. By repeated pressing-decompression, the filter medium 13 is 'washed out' as if it is a laundry, and the washing water is absorbed into the filter medium 13 when it is squeezed out of the filter medium layer 10 and decompressed. When pressed again, the remaining foreign matter is squeezed and eliminated and removed quickly and effectively. When the concentration of the foreign matter remaining in the filter medium layer 10 and the concentration of the foreign matter dropped into the washing water is similar, the filter water layer 10 is replaced with the washing water and then the above process is repeated. Of course, backwashing can occur simultaneously. When considering backwashing, install a backwashing water supply pipe 34 at the top.

본 발명에 의한 상향류 여과조가 여과운전을 하는 동안, 역세척운전을 하는 동안, 보다 완전한 세척을 위한 린즈운전을 하는 동안의 처리수 또는 세척수의 흐름을 각각 도 3a~3c에 도시하였다. 도면에서 적색 화살표가 처리수 또는 세척수의 흐름을 나타낸다. 도면에서는 역세척을 위한 역세척급수관과, 린즈를 위한 린즈수이송관(35)이 설치된 것을 예시하였다.
The flow of the treated water or the wash water during the upstream filtration tank according to the present invention during the filtration operation, during the backwash operation, and during the rinse operation for a more complete washing is shown in FIGS. 3A to 3C, respectively. Red arrows in the figure indicate the flow of treated or washed water. In the drawings, a backwash water supply pipe for backwashing and a rinse water transport pipe 35 for rinse are illustrated.

이러한 방식에 의해 본 발명에 의한 상향류 여과조는 종래 단순한 역세에 의한 여과재(13) 표면만의 세척에 비해 세척에 사용되는 세척수의 양도 월등히 적고 세척에 소요되는 시간도 대폭 줄어든다. 본 발명자들의 간이실험에 의하면 동일한 규격의 여과조일 때 본 발명에 의한 것은 종래기술(등록특허 10-0796013)의 여과조에 비해 처리능력은 2~5배, 역세척회수는 1/2(하루 1회)로 충분하며, 세척시 소요되는 세척수도 여과수량의 1% 이내로서 종래기술의 2~4%에 비해 월등히 적은 효과를 보인다.
In this way, the upflow filtration tank according to the present invention has a much smaller amount of washing water used for washing than the conventional washing of only the surface of the filter medium 13 by simple backwashing, and the time required for washing is greatly reduced. According to the simple experiments of the present inventors, when the same size of the filtration tank according to the present invention compared to the filtration tank of the prior art (Registered Patent No. 10-0796013), the processing capacity is 2 to 5 times, the backwash number is 1/2 (once a day) ), And the washing water required for washing is also less than 1% of the filtered water, which is much less effective than 2 to 4% of the prior art.

한편, 본 발명에서는 전술한 세척의 효과뿐만 아니라 여과재(13)의 압착정도를 조절함으로써 처리수의 특성(이물질을 얼마나 함유하고 있는지... 등)이나 수량, 방출수의 목표수질 등의 변동에 용이하게 대응할 수 있는 장점이 있다. 즉, 예를 들면 처리수에 제거해야 할 이물질이 적고 처리수량이 많은 경우에는 여과재(13)의 압착정도를 약하게 하여 처리수의 통과저항을 낮춤으로써 대용량 처리가 가능하며, 제거해야 할 이물질이 많거나 방출수 수질 기준이 높은 경우 여과재(13)의 압착정도를 강하게 하여 이물질의 통과가 매우 어려워지도록 하는 것이다. 본 발명의 이러한 운용특성은 종래 여과조로는 얻을 수 없는 독특한 것이다.
On the other hand, in the present invention, by controlling the degree of compression of the filter medium 13 as well as the effect of the above-described washing, it is possible to change the characteristics of the treated water (how much foreign matters, etc.), the quantity, the target water quality of the discharged water, and the like. There is an advantage that can be easily responded. That is, for example, when there are few foreign matters to be removed in the treated water and the amount of the treated water is high, a large amount of the foreign matter to be removed is possible by lowering the resistance of the treated water by weakening the crimping degree of the filter medium 13. In addition, when the discharge water quality standard is high, the degree of compression of the filter medium 13 is increased so that the passage of foreign matter becomes very difficult. This operating characteristic of the present invention is unique that cannot be obtained with a conventional filtration tank.

본 발명에서 상기 여과재(13)는 판형상의 스펀지이거나 상기 투수공을 통과하지 못하는 크기의 다양한 형상의 스펀지 조각인 것이 바람직하다.
In the present invention, it is preferable that the filter medium 13 is a plate-shaped sponge or sponge pieces of various shapes having a size that does not pass through the perforation hole.

본 발명에 의한 수처리용 상향류 여과조에서, 상기 유출관(32)보다 높은 곳에 수평으로 위어가 형성되어 있고, 위어를 월류한 여과수가 유출관(32)으로 유출되도록 하는 것이 좋다.
In the upstream filtration tank for water treatment according to the present invention, the weir is formed horizontally higher than the outlet pipe 32, it is good to let the filtered water that has passed the weir to the outlet pipe (32).
