Description

위치에너지를 이용한 다단식 폐수처리장치{Apparatus for disposing waste water}Multi-stage wastewater treatment system using potential energy {Apparatus for disposing waste water}

본 발명은 위치에너지를 이용한 다단식 폐수처리장치에 관한 것으로서 좀더 상세하게 설명하면 호기성 미생물담체와 혐기성 미생물 담체를 구비하는 수조를 다단(多段)으로 적층하고, 가장 상부의 수조로 부터 폐수를 흘려보내면서 반복적으로 호기성 미생물담체와 혐기성 미생물 담체에 의해 순차적으로 정화되도록 하기 위한 위치에너지를 이용한 다단식 폐수처리장치에 관한 것이다.
The present invention relates to a multi-stage wastewater treatment apparatus using potential energy, which will be described in more detail. The tank comprising aerobic microbial carriers and anaerobic microbial carriers is stacked in multiple stages, and the wastewater flows from the uppermost tank. It relates to a multi-stage wastewater treatment apparatus using potential energy to be sequentially purified by aerobic microbial carrier and anaerobic microbial carrier.

산업이 고도로 발달함에 따라 환경오염의 심각성은 날로 대두되고 있다. 특히, 가정이나 공장, 혹은 축사 등에서 방출되는 오폐수, 공장 폐수, 축산 폐수 등(이하, 이들을 통틀어 '유기성폐수'라 함)은 지하수 및 하천으로 흘러 결국에는 바다를 오염시키게 된다. 이처럼 유기성폐수를 처리하여 정화하지 않고 그대로 방류하면 각종 유기물, 미생물 및 질소(N), 인(P) 등으로 인해 하천 등의 부영화 현상을 초래하며 이로 인해 수중 생태계가 파될 뿐만 아니라 토양의 오염을 유발하여 생활환경이나 생태계의 먹이사슬까지 파괴함으로써 인간의 생존권을 위협할 수밖에 없다.As the industry is highly developed, the seriousness of environmental pollution is increasing day by day. In particular, wastewater, factory wastewater, and livestock wastewater (hereinafter, collectively referred to as 'organic wastewater') emitted from homes, factories, or livestock farms flow to groundwater and rivers, and eventually pollute the sea. As such, when organic wastewater is treated and discharged without purification, various organic matters, microorganisms, nitrogen (N), phosphorus (P), etc., cause the sublimation phenomenon of rivers, etc. By destroying the living environment and even the food chain of the ecosystem, we have no choice but to threaten human right to life.

물론, 이와 같은 피해를 줄이기 위해서는 근본적으로 유기성폐수의 배출을 줄이는 것이 가장 바람직하겠지만 산업이 발달함에 따라 각종 유기성폐수의 배출은 불가피한 실정이다. 이에, 이러한 유기성폐수를 적절하게 처리할 수 있는 방법의 개발이 필요한 바, 근자에 들어서는 각계 각층에서는 유기성폐수를 처리할 수 있도록 한 유기성폐수 처리방법에 대해 수많은 연구개발과 투자가 이루어지고 있는 실정이다. Of course, in order to reduce such damages, it is most desirable to basically reduce the emission of organic wastewater, but as the industry develops, the discharge of various organic wastewater is inevitable. Therefore, it is necessary to develop a method for properly treating such organic wastewater, and in recent years, many research and development and investments have been made on organic wastewater treatment methods for treating organic wastewater in various layers. .

유기성폐수를 처리하는 종래의 방법에는 크게, 물리적 처리방법 및 화학적 처리방법 또는 생물학적처리 방법을 병합하여 유기성폐수를 처리하는 방법이 있다. 그러나, 이러한 전형적인 처리방법은 다분히 임의적이고 처리대상 유기성 폐수의 성상, 목표 제거율, 처리시설의 특징 등의 변화에 빠르게 대처하지 못하는 단점이 있다.Conventional methods for treating organic wastewater include a method of treating organic wastewater by combining physical treatment, chemical treatment or biological treatment. However, such a typical treatment method is much arbitrary and has a disadvantage in that it does not cope quickly with changes in the characteristics of the organic wastewater to be treated, the target removal rate, and the characteristics of the treatment facility.

또한, 종래에 공지된 유기성폐수 처리방법 중, 주로 사용된 활성오니법에 의 하면, 비교적 많은 양의 슬러지가 발생되고 고액분리를 위한 처리 약품의 과다사용으로 유지비가 많이 소요될 뿐만 아니라 그 처리능력 또한 저조한 단점이 있다.In addition, in the conventionally known organic wastewater treatment method, the activated sludge method is mainly used, a relatively large amount of sludge is generated, and the maintenance cost is not only high due to the excessive use of the treatment chemical for solid-liquid separation, There is a disadvantage.

특히, 질소화합물과 인화합물의 처리에는 난분해성으로 인하여 처리능력이 현저히 떨어지며, 이를 하천이나 호수 및 바다에 방류하게 되면 적조현상의 발생에 의한 용존산소의 결핍으로 인하여 수생태계의 파괴를 유발시키는 원인을 야기한다.In particular, the treatment of nitrogen compounds and phosphorus compounds is considerably degraded due to poor degradability, and when discharged into rivers, lakes, and seas, the cause of destruction of aquatic ecosystems due to the lack of dissolved oxygen caused by the red tide phenomenon. Cause.

그리고, 종래에는 폐수처리 장치의 설치비용 및 설치면적의 과다로 인하여 효율적인 국토 이용에 문제가 있으며, 특히 폐수처리를 위한 수조를 수평적으로 배치함으로써 반복적으로 펑핌해야 하는 등 많은 에너지의 낭비를 유발하는 단점을 갖는 것이다.
In addition, in the related art, there is a problem in the efficient use of land due to the excessive installation cost and the installation area of the wastewater treatment device. It has a disadvantage.

본 발명은 상기와 같은 문제점을 해결하기 위하여 개발된 것으로서, 유기성폐수를 호기성 미생물담체와 혐기성 미생물 담체에 의해 순차적으로, 특히 반복적으로 정화되도록 하되 최소의 면적으로 최대의 정화효과를 얻을 수 있도록 하는 위치에너지를 이용한 다단식 폐수처리장치를 제공하기 위한 것이다.
The present invention has been developed in order to solve the above problems, the organic waste water to be purified sequentially, in particular repeatedly by the aerobic microbial carrier and anaerobic microbial carrier, but the position to obtain the maximum purification effect with a minimum area It is to provide a multi-stage wastewater treatment apparatus using energy.

상기와 같은 목적을 달성하기 위하여 본 발명은 호기성 현수식 미생물담체와 혐기성 유동상 미생물 담체를 구비하는 수조를 다단(多段)으로 적층하여 배치하되, 수조의 내부에는 혐기성 유동상 미생물 담체를 채우고, 수조의 가장자리 외측면에는 호기성 현수식 미생물담체를 매달아 수조 내부에서 혐기성 유동상 미생물 담체에 의해 일부 정화된 폐수가 수조를 넘치면서 다시 호기성 현수식 미생물담체에 의해 정화되도록 함으로서 폐수가 최상단의 수조에서 최하단의 수조를 거치면서 호기성 미생물담체와 혐기성 미생물 담체에 의해 반복적으로 정화되도록 구성됨을 특징으로 한다.
In order to achieve the above object, the present invention is arranged by stacking a multi-stage tank having an aerobic suspension-type microbial carrier and anaerobic fluidized bed microbial carrier, filling the anaerobic fluidized bed microbial carrier in the tank, The aerobic suspended microbial carriers are suspended from the edge of the tank so that the wastewater partially purified by anaerobic fluidized bed microbial carriers within the tank is purified by the aerobic suspended microbial carriers as it overflows the tank and is again the lowest tank in the top tank. It is characterized in that it is configured to be repeatedly purified by aerobic microbial carriers and anaerobic microbial carriers.

상술한 바와 같이 본 발명은 각각 다른 오염원에 효과적인 호기성 미생물담체와 혐기성 미생물 담체를 순차적으로, 또 반복적으로 형성함으로써 폐수가 효과적으로 정화되도록 하였다.As described above, the present invention allows the wastewater to be effectively purified by sequentially and repeatedly forming an aerobic microbial carrier and an anaerobic microbial carrier effective for different pollutants.

또 본 발명은 위로 올라갈 수록 직경이 줄어드는 수조를 최상단으로 부터 최하단까지 반복하여 적층함으로써 폐수처리장의 좁은 공간을 최대한 활용할 수 있도록 하는 효과를 갖는다.In addition, the present invention has the effect of making the most of the narrow space of the wastewater treatment plant by repeatedly stacking the water tank, the diameter of which decreases upward from the top to the bottom.

또 본 발명은 수조의 가장자리 외측면을 경사지게 형성하고, 상기 경사면에 호기성 현수식 미생물담체를 매달아 수조를 넘치는 물이 자연스럽게 수조의 외측면을 타고 흐르면서 호기성 미생물담체에 의해 정화되도록 하는 효과를 갖는다.In addition, the present invention has an effect that the outer surface of the edge of the tank is formed to be inclined, and the aerobic suspension-type microbial carrier is suspended on the inclined surface so that the water overflowing the tank naturally flows through the outer surface of the tank to be purified by the aerobic microbial carrier.

또한 본 발명은 한번의 펌핑으로 최상단 수조 위에서 쏟아진 폐수가 위치에너지에 의해 하부에 있는 수조로 순차적으로 떨어지면서 정화되도록 함으로써 에너지의 절감이 가능하도록 하는 매우 유용한 발명인 것이다.
In addition, the present invention is a very useful invention that enables the reduction of energy by allowing the wastewater spilled on the uppermost tank by one pumping to be purified by falling into the lower tank by the potential energy.

이에 본 발명의 구성을 첨부된 도면에 의하여 당업자가 용이하게 이해하고 재현할 수 있도록 상세하게 설명하면 다음과 같다.Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

본 발명은 배수관(1410)를 구비하는 외부수조(1400)와, 상기 외부수조(1400) 내측 중앙에 형성되며 외부수조(1400)보다는 직경이 작은 최하단 수조(1300)와, 상기 최하단 수조(1300)의 중앙 상부에 지지대(1500)에 의해 지지되어 형성되며 최하단 수조(1300) 보다는 직경이 작은 중간 수조(1200)와, 상기 중간 수조(1200)의 중앙 상부에 지지대(1500)에 의해 지지되어 형성되며 중간 수조(1200) 보다는 직경이 작은 최상단 수조(1100)와, 상기 최상단 수조(1100) 상부에 형성되는 폐수공급관(100)으로 이루어지되, 상기 외부수조(1400) 위에 각각 적층되어 배치되는 다수개의 수조(1100,1200,1300)의 외측면은 경사지게 형성하여 경사면(1101,1201,1301)을 형성하고, 상기 경사면(1101,1201,1301)의 상단에는 걸이구(1112)를 형성하여 호기성 미생물 담체(1120,1220,1320)가 경사면(1101,1201,1301)을 빙둘러서 현수되도록 하여 수조(1100,1200,1300,1400)를 넘친 폐수는 호기성 미생물 담체(1120,1220,1320)에 의해 정화되도록 하며, 수조(1100,1200,1300,1400) 내부로 유입되는 폐수는 수조(1100,1200,1300,1400) 내부에 채워진 혐기성 미생물담체(1130,1230,1330,1430)에 의해서 정화될 수 있도록 구성된다.The present invention has an outer tank 1400 having a drain pipe 1410, the lowermost tank 1300 having a smaller diameter than the outer tank 1400 and formed in the inner center of the outer tank 1400, and the lowest tank 1300. Is formed by being supported by the support 1500 in the center upper portion of the middle tank 1200 of smaller diameter than the lowermost tank 1300, and is supported by the support 1500 in the center of the middle tank 1200 A plurality of tanks consisting of a top tank 1100 having a smaller diameter than the middle tank 1200 and a waste water supply pipe 100 formed on the top tank 1100, respectively stacked on the outer tank 1400. The outer surface of the (1100, 1200, 1300) is formed to be inclined to form inclined surfaces (1101, 1201, 1301), and the hooks 1112 are formed on the top of the inclined surfaces (1101, 1201, 1301) to form an aerobic microorganism carrier ( 1120, 1220, 1320 round the inclined surfaces 1101,1201,1301 Waste water overflowing the tanks (1100, 1200, 1300, 1400) to be purified by aerobic microbial carriers (1120, 1220, 1320), and waste water flowing into the tanks (1100, 1200, 1300, 1400) It is configured to be purified by the anaerobic microbial carriers (1130, 1230, 1330, 1430) filled in (1100, 1200, 1300, 1400).

이때 상기 걸이구(1112)는 호기성 미생물 담체의 걸고리(1121)가 걸려서 현수될 수만 있는 구성이면 무방하다 할 것이나, 도 1에 도시된 바와 같이 수조(1100,1200,1300)의 상단 가장자리에 오목하게 홈을 형성하여 걸이구(1112)를 형성할 수도 있다. 상기와 같이 수조(1100,1200,1300)의 상단 가장자리에 오목하게 홈을 형성하여 걸이구를 형성하게 되면 수조를 넘치는 물이 오목홈을 넘쳐 흐르게 되고 결국 호기성 미생물 담체로 유도되어 호기성 미생물 담체를 따라 흐르게 되므로 폐수 정화효율은 향상되는 구조이다. In this case, the hook 1112 may be configured to be suspended only by hanging the hook 1121 of the aerobic microorganism carrier, but as shown in FIG. 1, it is concave at the upper edge of the tank 1100, 1200, 1300. The hanger 1112 may be formed by forming a groove. As described above, when the grooves are formed by concave grooves formed at the upper edges of the tanks 1100, 1200, and 1300, water overflowing the tank flows over the concave grooves and eventually leads to the aerobic microbial carriers and thus along the aerobic microbial carriers. As it flows, wastewater purification efficiency is improved.

본 발명에 사용되는 호기성 미생물담체(1120,1220,1320)는 다양한 종류가 사용될 수 있으나 섬유상 미생물 담체를 사용함이 바람직하고, 혐기성 미생물담체(1130,1230,1330,1430)은 세라믹 또는 플라스틱, 탄소섬유재질의 유동상 담체를 사용함이 바람직하다.The aerobic microbial carrier (1120, 1220, 1320) used in the present invention may be used in various kinds, but it is preferable to use a fibrous microbial carrier, anaerobic microbial carrier (1130, 1230, 1330, 1430) is a ceramic or plastic, carbon fiber It is preferable to use a fluidized bed carrier of the material.

이처럼 본 발명은 폐수가 최상부에 형성되는 폐수공급관(100)에 의해 최상단에 위치한 수조(1100)에 공급되는 구조이며, 상기 최상단 수조(1100)에 채워진 혐기성 미생물담체(1130)에 의해 일부 정화된 폐수는 결국 최상단 수조(1100)를 넘치게 되고, 이때 넘친 폐수는 최상단 수조(1100)의 경사면(1101)에 빙둘러서 현수된 호기성 미생물담체(1120)를 타고 흐르면서 상기 호기성 미생물담체(1120)에 서식하고 있는 미생물에 의해 오염물질이 섭취되어 정화된다.As such, the present invention is a structure in which the wastewater is supplied to the water tank 1100 positioned at the top by the wastewater supply pipe 100 formed at the top thereof, and the wastewater partially purified by the anaerobic microbial carrier 1130 filled in the top tank 1100. Eventually, the top tank 1100 overflows, and the overflowed waste water flows on the aerobic microbial carrier 1120 suspended around the inclined surface 1101 of the top tank 1100 and inhabits the aerobic microbial carrier 1120. Pollutants are ingested and purified by microorganisms.

이처럼 최상단 수조(1100)를 넘친 폐수는 다음 수조, 즉 중간 수조(1200)에 공급되며, 역시 상기 중간 수조(1200)에 채워진 혐기성 미생물담체(1230)에 의해 폐수는 일부 정화되고, 다시 중간 수조(1200)를 넘치게 되면서 중간 수조(1200)의 경사면(1201)에 빙둘러서 현수된 호기성 미생물담체(1220)를 타고 흐르면서 정화된다.The wastewater overflowing the top tank 1100 is supplied to the next tank, that is, the intermediate tank 1200, and the wastewater is partially purified by the anaerobic microbial carrier 1230, which is also filled in the intermediate tank 1200, and again, the intermediate tank ( As it overflows 1200, it is purged while flowing on the aerobic microbial carrier 1220 suspended around the inclined surface 1201 of the intermediate water tank 1200.

이와 같이 반복되는 구조로 최하단 수조(1300)로 공급된 폐수 역시 동일한 순서로 혐기성 미생물담체(1330)와 호기성 미생물담체(1320)에 의해 정화된 다음 외부수조(1400)로 정화된 폐수, 즉 정수를 배출하게 되고 외부수조(1400)로 유입된 정수는 배수관(1410)를 통해 배출되어 진다.
The wastewater supplied to the lowermost tank 1300 in a repeating structure as described above is also purified in the same order by the anaerobic microbial carrier 1330 and the aerobic microbial carrier 1320 and then purified by an external tank 1400, that is, purified water. The purified water introduced into the external water tank 1400 is discharged through the drain pipe 1410.
