본 발명은 오폐수(이하 하수로 통칭함)에 포함된 질소 및 인을 생물학적으로 고도처리하여서 정수를 얻기 위한 것으로, 특히 동력을 이용하지 않고 처리대상의 원수를 혐기조, 무산소조, 포기조 내에 골고루 신속하게 확산시킬 수 있도록 한 하수처리장치에 관한 것이다.The present invention is to obtain purified water by biologically advanced treatment of nitrogen and phosphorus contained in the waste water (hereinafter referred to as sewage), in particular, evenly spreading the raw water of the treatment target in the anaerobic tank, anaerobic tank, aeration tank evenly It relates to a sewage treatment device that can be made.

하수는 다량의 질소와 인을 포함하고 있어 처리되지 않은 상태로 방류되면 하천수의 심각한 오염을 초래하게 되는 바, 이러한 하수를 생물학적으로 고도처리하기 위한 하수처리장치들이 이미 개발되어서 유용하게 활용되고 있다.Since sewage contains a large amount of nitrogen and phosphorus, when discharged untreated, it causes severe pollution of the river water. Sewage treatment devices for biologically advanced sewage have already been developed and utilized.

종래의 생물학적 고도처리를 위한 하수처리장치는 혐기조, 무산소조, 포기조 및 침전조를 유기적으로 조합하여 유입 원수에 포함된 질소와 인을 제거할 수 있도록 구성되었다. 즉, 혐기조에서는 유입 원수에 함유된 BOD 및 COD 등과 같은 유기탄소원을 이용하여 활성슬러지로부터 인을 방출하는 혐기 반응을 일으키고, 무산소조에서는 혐기조로부터 유입된 원수에 소모되고 남은 유기탄소원을 이용하여 포기조에서 반송되는 슬러지 혼합액에 함유된 질산성 질소(NO3-N)를 질소가스(N2)로 환원시켜 대기중에 방출하는 무산소 반응을 일으키며, 포기조에서는 공급되는 산소를 이용하여 무산소조로부터 유입된 원수에 함유된 유기물 및 질소성분을 산화시키는 동시에, 혐기조에서 방출된 인의 양보다 더 많은 양의 인을 과잉섭취하여 원수에 함유된 인을 제거하는 호기 반응을 일으키고, 침전조에서는 포기조에서 유입된 원수를 고액분리하여 활성슬러지는 혐기조로 반송하고 잉여슬러지는 방출하여서, 처리대상의 원수에 포함된 질소와 인이 제거된 정수를 얻을 수 있도록 하였다.Conventional sewage treatment apparatus for advanced biological treatment is configured to remove nitrogen and phosphorus contained in the influent raw water by organic combination of anaerobic tank, anoxic tank, aeration tank and sedimentation tank. That is, in the anaerobic tank, an anaerobic reaction that releases phosphorus from activated sludge is carried out using organic carbon sources such as BOD and COD contained in the influent raw water, and in an anaerobic tank, the organic carbon source consumed from the anaerobic tank is returned and returned from the aeration tank. Nitric acid nitrogen (NO 3 -N) contained in the sludge mixture to be reduced to nitrogen gas (N 2 ) to cause an anoxic reaction that is released to the atmosphere, in the aeration tank using the oxygen supplied in the raw water introduced from the anoxic tank At the same time, it oxidizes organic matter and nitrogen, and induces an aerobic reaction to remove phosphorus contained in raw water by overingesting more phosphorus than phosphorus released from anaerobic tank. The sludge is returned to the anaerobic tank and the surplus sludge is discharged so that the quality of the raw water The purified water from which bovine and phosphorus were removed was obtained.

그러나, 이와 같은 하수처리장치에서 처리대상의 원수가 미생물과 접촉하여 반응하게 되는 혐기조, 무산소조, 포기조는 각각 원수가 상부로 월류되어서 유입되고 자연적으로 대류순환되면서 확산되도록 구성되어 있기 때문에, 그 혐기조, 무산소조, 포기조 내에 각각 유입된 원수의 확산속도가 느리고 편중되는 현상이 발생되므로, 원수와 미생물이 접촉할 기회가 감소되어 처리효율이 저하될 뿐만 아니라, 원수와 미생물이 충분히 접촉하는 데 소요되는 시간이 길어져서 처리시간이 연장되는 등의 문제점을 수반하게 되었다.However, the anaerobic tank, anoxic tank, and aeration tank in which the raw water to be treated in this sewage treatment system reacts with the microorganisms are each configured to spread as the raw water flows upward and flows naturally in a convective circulation. As the diffusion rate of raw water introduced into the anoxic tank and the aeration tank is slow and biased, the chance of contact between raw water and microorganisms is reduced, and the treatment efficiency is lowered, and the time required for sufficient contact between raw water and microorganisms is reduced. This has been accompanied by problems such as longer processing time.

한편, 상기한 문제점을 해결하고자 하수처리장치의 혐기조, 무산소조, 포기조 내에 각각 유입된 원수를 강제적으로 확산시킬 수 있도록 회전날개를 가지는 반응촉진장비를 설치하는 방법이 고려될 수 있지만, 이 반응촉진장비는 과도한 설비비용이 소요되고, 동력원으로 전력을 사용하게 되므로 운용비를 상승시키는 결과를 초래하게 되었다.On the other hand, in order to solve the above problems, a method of installing a reaction promoting device having a rotary blade to forcibly diffuse the raw water introduced into the anaerobic tank, the anoxic tank and the aeration tank of the sewage treatment apparatus may be considered. The cost of the plant is excessive and the use of power as a power source has resulted in an increase in operating costs.

본 발명은 수두차를 이용하여 각 반응조 내에 유입되는 처리대상의 원수를 골고루 신속하게 확산시킬 수 있도록 구성하여서, 첫째 원수의 처리효율을 극대화하여 주는 하수처리장치를 제공하는 데 목적이 있으며, 둘째 동력 사용을 최대한 억제하여서 운용상의 경제성을 제고하여 주는 하수처리장치를 제공하는 데 목적이 있다.An object of the present invention is to provide a sewage treatment apparatus that maximizes the treatment efficiency of the first raw water by configuring to spread the raw water of the treatment target flowing into each reaction tank evenly and quickly using the water head difference. It is an object of the present invention to provide a sewage treatment system that minimizes the use and improves the economics of operation.

본 발명도 혐기조(10), 무산소조(20), 포기조(30)의 조합에 의하여 유입된 하수를 처리하도록 구성된 점에 있어서는 종래의 것과 기술개념을 같이 한다.The present invention also has the same technical concept as the conventional one in that it is configured to treat the sewage introduced by the combination of the anaerobic tank 10, the anaerobic tank 20, and the aeration tank 30.

단, 본 발명의 하수처리장치는 도 1에 도시되는 바와 같이, 상기 혐기조(10), 무산소조(20), 포기조(30)는 그 각각의 내부에 처리 대상의 원수를 수두차에 의하여 분출하도록 배관되며 복수개의 분출공(11a, 21a, 31a)들이 배열 형성되는 반응촉진용 분출관(11, 21, 31)을 구비하여서 됨을 기술구성상의 특징으로 한다.However, the sewage treatment apparatus of the present invention, as shown in Figure 1, the anaerobic tank 10, anoxic tank 20, aeration tank 30 is piped so as to eject the raw water of the object to be treated by water head in each of the inside And it characterized in that the technical configuration characterized in that the plurality of ejection holes (11a, 21a, 31a) is provided with a reaction promoting ejection pipe (11, 21, 31) arranged in an array.

이와 같이 본 발명의 하수처리장치는 혐기조(10), 무산소조(20), 포기조(30) 내에 각각 동력을 이용하지 않고 수두차에 의하여 원수를 분출시켜서 골고루 신속하게 확산되게 하는 반응촉진용 분출관(11, 21, 31)을 갖추어서, 원수가 미생물과 접촉할 기회를 증대시켜서 처리효율을 향상시켜 줄뿐만 아니라, 원수가 미생물과 충분히 접촉하는 데 소요되는 시간을 줄여서 처리시간을 단축시켜 주는 등의 장점을 가지게 되는 것이다.Thus, the sewage treatment apparatus of the present invention is the anaerobic tank (10), anoxic tank (20), aeration tank for reaction promotion to evenly spread evenly by ejecting the raw water by water head without using power in each (30) ( 11, 21, 31), which not only improves the treatment efficiency by increasing the chance of raw water coming into contact with microorganisms, but also shortens the processing time by reducing the time required for the raw water to come in contact with microorganisms. You will have an advantage.
