Description
본 발명은 각종 생활오수나 산업용 폐수를 생물학적 방법인 활성 슬럿지 방법으로 처리할 수 있도록 함에 있어서, 수조내로 유입된 폐수를 수조내에서 체류시키도록 하고, 상기 수조내에서 체류되는 폐수가 활성 슬럿지방법에 의한 단계적 비연속 반응(Sequencing Batch Reactor)인 회분식으로 처리되도록 하므로써 상기 폐수의 처리를 원활하고 효과적으로 할 수 있도록 한 생물학적 소형 폐수 처리시스템에 관한 것이다.The present invention allows to treat various domestic sewage or industrial wastewater by the active sludge method, which is a biological method, to allow the wastewater introduced into the tank to be retained in the tank, and the wastewater remaining in the tank is activated sludge method. The present invention relates to a biological compact wastewater treatment system that allows the wastewater to be treated smoothly and effectively by being treated in a batch, a sequencing batch reactor.
일반적으로 가정등에서 발생되는 생활 폐수나 산업용 폐수들은 그대로 방출할 경우, 토지의 오염은 물론, 수자원을 파괴하는 등 환경오염을 야기시키게 되므로 상기 폐수는 정화시킨 상태에서 방출해야만 하며, 상기 폐수를 정화시키면서 방출할 수 있도록 폐수를 유입하고 이 유입된 폐수를 호기, 혐기, 침전시킨 다음 이를 유출하도록 하는 정화 시스템이 안출되어 이용하고 있었다.In general, when domestic wastewater or industrial wastewater generated from homes is discharged as it is, it causes pollution of the land as well as destroying water resources. Therefore, the wastewater should be discharged in a purified state. A clean-up system was introduced to utilize the wastewater to discharge it, to exhale, anaerobic, and settle the wastewater, and then to discharge it.
한편, 현재 이용되고 있는 각종 정화 시스템은 수조로 유입되는 폐수를 교반시키면서 상기 수조내에서 여과망에 의한 필터링을 하도록 하고, 상기 필터링된 폐수에 폐수를 분해시키는 화학약품을 혼합시켜 정화시키도록 되어 있었으며, 상기 정화된 폐수를 방출하여 상기 정화 시스템이 작용하도록 구성되어 있었다.On the other hand, various purification systems currently being used to filter by the filtering network in the tank while stirring the wastewater flowing into the tank, and to mix and purify the chemical to decompose the wastewater to the filtered wastewater, The purification system was configured to discharge the purified wastewater.
그러나, 상기와 같은 일반적인 폐수 처리방법은 상기 필터링에 따른 슬럿지의 제거작업이 매우 번거롭게 되었으며, 상기 화학약품에 의해서 상기 폐수를 분해시키고 이 분해된 폐수를 여러 차례 여과시키도록 되어 있었기 때문에 상기 폐수의 처리를 위한 시스템이 매우 방대하게 되는 폐단이 있었으며, 상기 폐수의 처리상태도 필터링 장치에 의존하기 때문에 폐수처리가 확실하게 이루어지지 못하면서 여과망이나 수조내에 많은 슬럿지를 양산하게 되는 결점이 있었고, 이를 제거하기 작업이 방대하게 되면서 지속적인 폐수의 처리가 이루어지지 못하는 점등의 문제점이 있었다.However, in the general wastewater treatment method, the removal of sludge due to the filtering becomes very cumbersome, and since the wastewater is decomposed by the chemical and the decomposed wastewater is filtered several times. There was a defect that the system was very large, and the wastewater treatment condition also depends on the filtering device, so there was a defect that mass production of a lot of sludge in the filtering network or the tank was not carried out with certainty. As it became immense, there was a problem of lighting that could not be made continuous treatment of wastewater.
본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 본 발명은 각종 생활오수나 산업용 폐수를 생물학적 방법인 활성 슬럿지 방법으로 처리할 수 있도록 함에 있어서, 수조내로 유입된 폐수를 수조내에서 체류시키도록 하고, 상기 수조내에서 체류되는 폐수가 활성 슬럿지방법에 의한 단계적 비연속 반응인 회분식으로 처리되도록 하므로써 상기 폐수의 처리를 원활하고 효과적으로 할 수 있도록 한 생물학적 소형 폐수 처리시스템을 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above-mentioned conventional problems, and the present invention enables the treatment of various household sewage and industrial wastewater by an active sludge method, which is a biological method, and the wastewater introduced into the tank in the tank. It is intended to provide a biological small wastewater treatment system that allows the wastewater retained in the tank to be treated in a batchwise manner, which is a stepwise discontinuous reaction by an active sludge method, to smoothly and effectively treat the wastewater. On the basis of the accompanying drawings, it will be described in detail as follows.

Emergency discharge through the emergency drain 15 provided, the waste accumulated in the emergency drain (15) through the waste discharge port (16) It is to be removed while being discharged by the vacuum truck.
또, 상기 수관(9)은 유입부 보다 유출부가 낮은 상태에 이르기까지 연장되는 연장관(17)을 형성하게 되면, 상기 처리수조(4)에서의 폐수를 유출구획부로 보다 원활하게 이송할 수 있게 되고, 상기 수관의 상부에 일수관(18)을 설치하여 상기 처리수조(4)에서 폐수가 넘치게 될 경우, 이 넘치는 량을 유출구획부로 일수시킬 수 있도록 한 것으로 상기 미세한 거품 포기상태와 생물학적 처리방법에 의하여 상기 폐수를 처리할 수 있도록 한 것이다.In addition, when the water pipe (9) forms an extension pipe (17) extending until the outlet portion is lower than the inlet portion, it is possible to more smoothly transfer the waste water from the treated water tank (4) to the outlet compartment. When the waste water overflows from the treated water tank 4 by installing the water pipe 18 on the upper portion of the water pipe, the amount of water overflows to the outlet compartment so that the fine bubble abandoned state and the biological treatment method It is to be able to treat the waste water.
또한, 상기 수관(9)의 처리수조(4)측에는 슬리브(19)를 설치하고, 상기 처리수조(4)에서의 상등수가 유츨될 경우, 상기 유출수의 수위에 맞추어 슬리브(19)를 승강시켜 수관(9)의 위치를 조정하도록 하므로써 상기 처리수조(4)에서의 상등수가 유출되지 않도록 한 것이다.In addition, a sleeve 19 is provided on the treated water tank 4 side of the water pipe 9, and when the supernatant water in the treated water tank 4 flows, the sleeve 19 is raised and lowered according to the level of the outflow water. By adjusting the position of (9), the supernatant water in the treatment tank 4 is prevented from flowing out.
이상과 같은 본 발명은 상기와 같이 유입되는 폐수를 침전시키고 이 침전이 이루어진 폐수를 기폭작용으로 미세한 거품 포기로 형성한 다음, 이를 유출구획부로 이송하고 생물학적 처리를 이용하여 처리하도록 하므로써 상기 폐수의 처리가 원활하게 되면서 확실한 처리가 이루어지게 되며, 상기 폐수처리에 따른 폐기물이나 슬럿지가 발생될 이를 용이하게 분리하여 배출시킬 수 있으며, 상기 처리 시스템을 소형으로 구비하여 설치할 수 있도록 하므로써 작은 규모로 이용할 수 있게 되고, 폐수의 처리시간이 짧게 되어 효율적인 폐수 처리가 이루어는 점등의 특징을 지닌 것이다.As described above, the present invention precipitates the wastewater introduced as described above, and forms the wastewater in which this precipitation is formed by aeration of fine bubbles, and then transfers it to the outlet compartment and treats the wastewater by treating it using biological treatment. Is made smoothly and a certain treatment is made, it is possible to easily separate and discharge the waste or sludge generated by the wastewater treatment, and to be able to use on a small scale by providing a compact installation of the treatment system In this case, the wastewater treatment time is shortened, and the wastewater has a characteristic of being lit.
