Abstract
Description
본 발명은 호기성 미생물에 의하여 오수 또는 폐수에 함유한 유기물을 분해하여 폐수를 정화하는 폐수정화조에 산소를 공급하는 장치에 관한 것으로서, 특히 폐수정화조에 공급되는 폐수에 미세화된 산소기포가 다량 함유하도록 하여 폐수의 정화효율을 향상 시킬 수 있는 산소공급장치에 관한 것이다.The present invention relates to a device for supplying oxygen to a wastewater purification tank for decomposing organic matter contained in sewage or wastewater by aerobic microorganisms to purify the wastewater, and in particular, to contain a large amount of micronized oxygen bubbles in the wastewater supplied to the wastewater purification tank. It relates to an oxygen supply device that can improve the purification efficiency of waste water.
일반적으로 유기성 폐수 정화처리에 있어서 미생물의 대사활동을 이용한 방법이 중심적인 기술이 되고 있다.In general, the method using the metabolic activity of microorganisms in organic wastewater purification treatment has become a central technology.
즉, 호기성 또는 혐기성 세균군의 생활환경을 적절히 조성해 주므로서 이들 미생물에 의한 유기오수중의 단백질, 탄수화물등을 분해, 섭취, 재합성하여 유기오수를 정화하는 것이다.That is, the organic wastewater is purified by decomposing, ingesting, and resynthesizing proteins and carbohydrates in organic wastewater by these microorganisms by appropriately creating a living environment of an aerobic or anaerobic bacterial group.
이러한 정화효율에 영향을 미치는 인자로는 기질(Substrate)농도, PH, 온도, 용존산소(DO, Dissolved Oxygen) 등이다.Factors affecting the purification efficiency include substrate concentration, PH, temperature, and dissolved oxygen (DO).
이중 기질농도나 온도 및 PH 등의 인자는 폐수자체가 갖고 있는 고유의 성질에 기인하게 되며, 외부에서의 인위적인 조작인자는 용존산소농도가 거의 유일하다고 할 수 있다. 다시말하면, 효율적인 산소공급이 정화효율을 좌우하는 중요한 요소가 되어지는 것이다.The factors such as substrate concentration, temperature, and pH are due to the intrinsic properties of the wastewater itself, and the external man-made manipulation factor is almost the only dissolved oxygen concentration. In other words, efficient oxygen supply becomes an important factor in determining purification efficiency.
이러한 산소공급을 위하여 통상 산기식 산소공급장치가 이용되고 있다. 산기식 산소공급장치는 송풍기(BIOWER)에 의해 외부 공기를 압송시켜 그 끝단에 구비된 여러형태의 산기장치에 의해 수많은 기포를 발생시키게 하므로서 그 기포들이 폭기조 저부로부터 상승하면서 폐수에 용해되게 하는 것이다.An oxygen type oxygen supply device is usually used for such oxygen supply. The acid-type oxygen supply device pressurizes the outside air by a blower to generate a large number of bubbles by various types of acid devices provided at the end thereof, so that the bubbles rise from the bottom of the aeration tank and dissolve in the waste water.
그러나, 산소는 액체에 대해 용해가 잘되지 않는 기체로 폭기조내에서 체류하는 시간이 짧을 경우 대부분 떠올라 대기중에 방출되고 만다.However, oxygen is a gas that is insoluble in liquids, and most of the oxygen is released to the atmosphere when the residence time in the aeration tank is short.
일반적인 산기식 산소공급장치를 사용하는 경우, 폐수의 농도, 온도, 폐수의 성상에 따라 다르나, 활성슬럿지법으로 운용되는 하수처리장에 있어서 산소흡수효율(흡수된 산소량/공급된 산소량)은 약 5 ∼ 8%에 불과하다.In case of using a general oxygen type oxygen supply device, depending on the concentration of wastewater, temperature, and characteristics of the wastewater, the oxygen absorption efficiency (absorbed oxygen amount / supplied oxygen amount) in the sewage treatment plant operated by the activated sludge method is about 5 to Only 8%.
즉, 100개의 산소를 공급하여 5 ∼ 8개만이 액체에 흡수 이용되고 나머지는 대기중에 방출되고 마는 것이다.In other words, by supplying 100 oxygen, only 5 to 8 are absorbed and used in the liquid, and the rest is released to the atmosphere.
한편, 산소가 액체로 전달되는 양은 기포와 액체의 접촉시간에 비례하게 된다. 이러한 접촉시간을 길게 하기 위해서는 폭기조내의 수심을 깊게 하여 기포의 체류시간을 연장시키는 방법이 있으나, 이럴경우 수심이 깊을수록 수압이 증가하게 되어 기포발생 장치인 송풍기의 전력 소요량이 많아지게 되며, 이에 따라 산소흡수효율의 증가효과를 전력비가 상쇄해 버리기 때문에 일반적으로 폭기조의 수심은 약 3 ∼ 8m 가 바람직한 것으로 알려져 있다.On the other hand, the amount of oxygen delivered to the liquid is proportional to the contact time of the bubble and the liquid. In order to lengthen the contact time, there is a method of extending the residence time of the bubble by deepening the depth in the aeration tank, but in this case, the deeper the water depth, the higher the water pressure, and thus the power demand of the blower, the bubble generator, increases. Since the power ratio cancels the effect of increasing the oxygen absorption efficiency, it is generally known that the depth of the aeration tank is preferably about 3 to 8 m.
이와같이 산소흡수효율을 높이기 위한 방안으로 기포와 폐수와의 접촉면적과 접촉시간을 늘리는 기술이 연구되고 있지만 접촉면적을 늘리기 위해서는 기포경을 최대한 미세화시키는 산기장치의 기술이 필요하게 되며, 또한 접촉시간을 늘리기 위해서는 폭기조의 수심을 깊게 하여야 함에도 불구하고 이럴경우 송풍기의 전력소요량이 증가되는 등의 문제점으로 한계가 있어 실제적으로는 극히 비효율적이고 비경제적인 폭기방식이 채택되고 있는 실정이다.In order to increase the oxygen absorption efficiency, techniques for increasing the contact area and the contact time between bubbles and wastewater have been studied, but in order to increase the contact area, the technique of an air diffuser that minimizes the bubble diameter is required. In order to increase the depth of the aeration tank to deepen, in this case, there are limitations such as the increase in the power consumption of the blower, which is practically extremely inefficient and inefficient economic aeration method is adopted.
본 발명자는 상기한 종래기술의 문제점을 해결하기 위하여 대한민국 특허등록번호 제187831호 "폐수의 호기성 생물처리에 있어서의 산기장치"를 발명한 바 있다.The inventor has invented the Republic of Korea Patent Registration No. 187831, "Aerator for the aerobic biological treatment of wastewater" to solve the above problems of the prior art.
상기 선출원 발명은 도 1에 도시된 바와 같이, 폐수가 저장되는 폭기조(1)와, 폭기조(1)의 바닥으로부터 이격 설치되고 상하단이 개방된 격벽통(2)과, 격벽통(2)의 상단유입구(2a)에 연결설치되는 폐수공급관(3)과, 폐수공급관(3)으로 폐수를 공급하는 가압펌프(P)와, 상기 폐수공급관에 연결되는 기포 발생장치(4)로 구성되어, 폐수가 가압펌프(P)로부터 송출되어 폐수공급관(3)을 통과할 때 기포발생장치(4)로부터 공급된 기포가 폐수에 섞이도록 한 다음, 격벽통(2)을 거쳐 폭기조(1)로 유입된다.The prior application is shown in Figure 1, the aeration tank 1, the waste water is stored, the bulkhead barrel 2 is installed spaced apart from the bottom of the aeration tank 1, the upper and lower ends are opened, the upper end of the partition barrel (2) Waste water supply pipe (3) connected to the inlet (2a), a pressurized pump (P) for supplying wastewater to the wastewater supply pipe (3), and bubble generator (4) connected to the wastewater supply pipe, waste water When the air is discharged from the pressure pump P and passes through the wastewater supply pipe 3, bubbles supplied from the bubble generator 4 are mixed with the wastewater, and then flow into the aeration tank 1 through the partition wall 2.
그러나, 상기한 선출원 발명은 기포발생장치(4)에 의하여 폐수에 공급되어 함유된 기포를 작게 형성하는데 한계가 있기 때문에 폐수와 기포의 접촉면적이 적게되어 폐수의 용존산소량이 충분하지 못함은 물론 폐수의 용존산소도 균일하지 못하여 폐수의 정화효율이 저감되는 문제점이 있었다.However, the above-described application of the present invention has a limitation in forming small bubbles contained in the wastewater supplied by the bubble generator 4, so that the contact area between the wastewater and the bubbles is small, and the amount of dissolved oxygen in the wastewater is not sufficient. Dissolved oxygen is also not uniform, there was a problem that the purification efficiency of the waste water is reduced.
본 발명은 상기한 종래기술의 제반 문제점을 해결하기 위하여 안출된 것으로서, 별도의 산기장치로 사용함이 없이 폐수정화조에 공급되는 폐수에 공기를 공급하여 자동적으로 폐수내에서 기포가 발생되도록 하는 호기성 생물 정화처리를 위한산소공급장치를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems of the prior art, aerobic biological purification to automatically generate air bubbles in the waste water by supplying air to the wastewater supplied to the wastewater purification tank without using as a separate air diffuser The object is to provide an oxygen supply device for the treatment.
또한, 본 발명은 용량이 적은 송풍기를 사용하면서도 폐수내에 미세한 기포가 발생되도록 하여 폐수와 접촉하는 기포의 체류시간을 증대시킴으로써, 폐수의 용존산소량을 높힐 수 있고 송풍기의 소요동력을 절감시킬 수 있는 호기성 생물 정화처리를 위한 산소공급장치를 제공하는데 있다.In addition, the present invention by using the air blower with a small capacity to generate fine bubbles in the waste water by increasing the residence time of the air bubbles in contact with the waste water, it is possible to increase the dissolved oxygen of the waste water and reduce the power required of the blower An oxygen supply apparatus for a biological purification treatment is provided.

이하, 첨부도면을 참조하여 본 발명의 실시예를 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
본 발명은 도 2, 도 3에 도시된 바와같이, 펌프(P)에 의하여 강제 유입된 폐수를 폐수정화처리조(60)로 배출시키는 벤츄리관(10)관과, 원통형관(30)으로 구성되고, 상기 벤츄리관(10)의 직경축소부(11)에는 공기공급관(12)이 연결되어 송풍기(B)에 의하여 송출된 공기가 상기 산소공급관(12)을 통하여 직경축소부(11)내로 공급된다.2 and 3, the present invention comprises a venturi tube (10) tube and a cylindrical tube (30) for discharging the wastewater forcedly introduced by the pump (P) to the wastewater purification treatment tank (60). The air supply pipe 12 is connected to the diameter reducing part 11 of the venturi tube 10, and the air supplied by the blower B is supplied into the diameter reducing part 11 through the oxygen supply pipe 12. do.
한편, 상기 벤츄리관(10)의 끝단과 원통형관(30)의 선단에는 플랜지(12)(31)가 각각 형성되고 상기 플랜지(12)(31) 사이에 오리피스(20)가 위치되어 볼트(41)로서 체결된다.Meanwhile, flanges 12 and 31 are formed at the end of the venturi tube 10 and the tip of the cylindrical tube 30, respectively, and an orifice 20 is positioned between the flanges 12 and 31 so that the bolts 41 may be positioned. Is fastened as
또한, 상기 원통형관(30)의 상측부 내부중앙에는 오리피스(20)을 통과한 폐수가 충돌하는 충돌판(50)이 고정설치되고, 상기 충돌판(50) 하측면에 진동판(51)의 일단이 부착된다.In addition, a collision plate 50 in which the wastewater passing through the orifice 20 collides is installed at the inner center of the upper portion of the cylindrical tube 30, and one end of the diaphragm 51 is disposed on the lower side of the collision plate 50. Is attached.
상기 진동판(51)은 도 4에 도시된 바와같이 폐수가 배출되는 방향으로 두께가 점차 두꺼워지는 직사각형의 판체(51a)로 형성되거나, 도 5에 도시된 바와 같이 두께가 얇은 한쌍의 직사각형의 판체(51b)가 폐수의 배출방향으로 상기 판체사이의 이격거리가 커지도록 이격되게 설치될 수 있다.As illustrated in FIG. 4, the diaphragm 51 is formed of a rectangular plate body 51a that becomes thicker in a direction in which wastewater is discharged, or a pair of rectangular plate bodies having a thin thickness as shown in FIG. 5 ( 51b) may be spaced apart so that the separation distance between the plates increases in the discharge direction of the wastewater.
이하, 본 발명의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.
호기성 생물 정화처리를 위한 폐수 또는 오수는 펌프(P)에 의하여 벤츄리관(10)으로 강제 유입되어 직경축소부(11)를 통과하게 되는데, 직경축소부(11)에는 공기공급관(12)을 통하여 송풍기(B)에서 송출된 공기가 공급되므로 직경축소부(11)를 통과한 폐수에 공기가 혼합된다.Wastewater or sewage for aerobic bio purification treatment is forced into the venturi tube 10 by the pump P and passes through the diameter reducing unit 11, and the diameter reducing unit 11 through the air supply pipe 12. Since the air sent from the blower (B) is supplied, the air is mixed with the wastewater passing through the diameter reduction section (11).
폐수에 함유된 공기는 벤츄리관(10)의 확개부(13)를 통과하면서 유속과 압력변화에 의하여 기포화가 촉진된 다음, 오리피스(20)를 통과하면서 다시 급격한 유속과 압력변화로 인하여 폐수에 함유된 공기의 기포화가 더욱 촉진된다.Air contained in the wastewater is bubbled by the flow rate and pressure change while passing through the expansion portion 13 of the venturi tube 10, and then contained in the wastewater due to the rapid flow rate and pressure change while passing through the orifice 20. The bubble of the air which is made is further promoted.
오리피스(20)를 통과한 폐수 및 기포는 충돌판(50)에 부딪쳐 기포가 다시 부서진 다음, 원통형관(30)을 통과하면서 폐수의 흐름에 따라 자동적으로 진동하는 진동판(51)에 의하여 극히 미세화되어 격벽통(61)을 통과한 다음,폐수정화처리조(60)의 하측으로 공급된다.Wastewater and bubbles that have passed through the orifice 20 are extremely fined by the diaphragm 51 which vibrates automatically upon the flow of the wastewater while passing through the cylindrical tube 30 when the bubbles collide again after colliding with the collision plate 50. After passing through the partition wall 61, it is supplied to the lower side of the waste water purification treatment tank 60.
본 발명은 폐수에 공급된 공기가 벤츄리관(10)을 통과하면서 유속과 압력변화에 의하여 미세기포가 된다음, 진동판(51)의 진동에 의한 진동에너지가 기·액혼합류에 전달되어 기체의 액체에의 용해가 촉진되며, 폐수에 함유된 기포의 체류시간이 증대되고 기포와 폐수의 접촉면적이 커지게 되어 폐수에 함유된 용존산소량이 증대되기 때문에 별도의 산기장치가 없이 폐수의 정화효율을 크게 향상시킬 수 있다.According to the present invention, the air supplied to the wastewater passes through the venturi tube 10 and becomes microbubbles due to the flow rate and pressure change. Then, the vibration energy caused by the vibration of the diaphragm 51 is transferred to the gas / liquid mixture flow to obtain the gas. Dissolution in liquids is promoted, the residence time of bubbles contained in waste water increases, the contact area between bubbles and waste water increases, and the amount of dissolved oxygen contained in waste water increases. It can greatly improve.
즉, 종래의 산기장치로 수심 3∼8m의 포기조에 산소를 전달 할 때는 포기조의 수심이 보통 3∼8m 이므로 0.3∼0.8㎏/㎠의 압력을 가진 송풍기가 사용되었는데 본 발명은 대기압 내지 0.05㎏/㎠ 정도의 압력을 갖는 저압 송풍기의 사용이 가능하고, 본 발명은 저압의 송풍기를 사용하기 때문에 같은 유량의 공기를 송출할 때, 종래 송풍기의 동력보다 1/8정도의 동력으로 송풍기의 작동이 가능하며, 소형 및 저압의 송풍기를 사용하므로 소음 및 진동이 대폭 저감된다.That is, when the oxygen is delivered to the aeration tank having a depth of 3 to 8m with a conventional diffuser, a blower having a pressure of 0.3 to 0.8㎏ / ㎠ is used since the depth of the aeration tank is usually 3 to 8m. It is possible to use a low pressure blower having a pressure of about 2 cm 2, and the present invention uses a low pressure blower, so that when the same flow rate of air is sent out, the blower can be operated with about 1/8 of the power of the conventional blower. In addition, noise and vibration are greatly reduced by using a compact and low pressure blower.
또한, 종래의 송풍기로 공기를 0.1㎏/㎠ 압축할 때 공기온도가 10℃씩 상승하며, 포기조의 수심이 3∼8m일 경우 0.3∼0.8㎏/㎠까지 압축하면 여름철 대기온도(35℃)를 포함해서 65∼115℃까지 공기온도가 상승하여 포기조 액은 상승의 주요인이 되어 미생물의 활성화를 저해하며 미생물 활성저하로 거품이 발생 되는데 본 발명은 저압의 송풍기를 사용하게 됨에 따라 포기조의 액온을 대기온도 정도(35℃)로 낮게 유지할 수 있어 미생물 활성저하가 없고 아울러 DO포화농도가 높아지고 거품발생 문제를 해소할 수 있다.In addition, when the air is compressed by 0.1kg / ㎠ with a conventional blower, the air temperature rises by 10 ℃, and when the depth of the aeration tank is 3 to 8m, when compressed to 0.3 ~ 0.8㎏ / ㎠ to increase the summer atmospheric temperature (35 ℃) Including air temperature rises up to 65-115 ° C, the aeration tank liquid becomes the main cause of the increase, inhibiting the activation of microorganisms, and bubbles are generated due to a decrease in the activity of microorganisms. It can be kept at a low temperature (35 ℃), so there is no deterioration of microbial activity, and the DO saturation concentration is increased, and foaming problems can be solved.
또한, 본 발명은 충돌판 및 진동판을 사용하여 기액혼합된 유체에 진동에너지를 주어 포기조에 산소전달능력을 상승시키는 효과가 발휘되고, 종래의 산기장치는 산소흡수효율이 5-8%인데 비해 본 발명을 사용하면 산소흡수효율을 대폭 향상시킬 수 있으므로 산소공급장치 설치비(산기장치, 배관, 송풍기) 및 유지관리비(전력비)를 기존방식에 비해 현저히 줄일 수 있고, 포기조의 수심에 제한을 받지않고 산소를 폐수에 공급할 수 있으며, 수심에 제한을 받지않아 부지멱적을 대폭 줄일 수 있는 효과가 있다.In addition, the present invention is to give the vibration energy to the gas-liquid mixed fluid using the impingement plate and the diaphragm to increase the oxygen transfer capacity to the aeration tank, the conventional acid diffuser has an oxygen absorption efficiency of 5-8% By using the invention, the oxygen absorption efficiency can be greatly improved, and thus the installation cost of oxygen supply equipment (acid equipment, piping, blower) and maintenance cost (power cost) can be significantly reduced compared to the existing method, and oxygen is not limited by the depth of the aeration tank. Can be supplied to the wastewater, and it is effective to drastically reduce the site area without being limited in depth.
