Description

오수처리시설의 슬러지 인발장치{The Sludge drawing equipment of sewage treatment facilities}Sludge drawing equipment of sewage treatment facility

본 발명은 오수처리시 발생되는 잉여슬러지(Sludge)를 인발하는 장치로서, 별도의 침전조를 설치하지 않고 반응조내에 인발관을 설치하여 필요시 적정량의 잉여 슬러지를 외부로 용이하게 인발해 낼 수 있는 장치이다.The present invention is a device for drawing out the sludge generated during the sewage treatment, the device which can easily draw out the appropriate amount of excess sludge to the outside by installing a draw pipe in the reaction tank without installing a separate settling tank to be.

일반적으로 기존의 오수처리시설은 별도의 슬러지 저류조를 만들어 침전조에서 이송된 슬러지를 모아두었다가 정기적으로 분뇨차량을 이용해서 적당량을 인발해가는 방법과 별도의 침전조가 없이 반응조에서 누적된 잉여슬러지를 분뇨차량을 이용해서 인발하는 방법을 이용해왔으나, 이는 사실 막대한 비용과 노력이 든다. 그 몇가지 문제점으로는,In general, existing sewage treatment facilities make a separate sludge storage tank to collect sludge transferred from the sedimentation tank and draw out an appropriate amount by using a manure vehicle on a regular basis, and surplus sludge accumulated in the reaction tank without a separate sedimentation tank. It has been used to draw using, but this is actually a huge cost and effort. Some of the problems are

1. 침전조 및 슬러지 저류조를 별도설치함으로써 들어가는 구조물의 설치 비용부담이 가중된다.1. The installation cost of the structure is increased by installing sedimentation tank and sludge storage tank separately.

2. 복잡한 설비나 별도의 설치공간이 필요하게 된다.2. Complex equipment or separate installation space is required.

3. 슬러지는 유기물 함량이 높아 부패성이 강하므로 악취발생과 구더기 및 파리발생등 위생적인 문제를 발생시키기도 한다.3. Sludge has high organic content and strong decay, which may cause hygienic problems such as odor, maggots and flies.

4. 반응조에서 직접 분뇨차량 인발기를 이용하여 잉여슬러지를 인발할 시는 바닥전면적에 쌓여있는 슬러지를 균등하게 인발 하기가 대단히 어렵고 슬러지 인발시 분뇨차의 강력한 흡인력으로 인하여 반응조 하부에 설치된 산소공급장치(산기관)를 건드려 고장이 발생하여 오수처리 시설의 기능을 저하시킬 수 있는 문제점 등이 있다.4. When drawing excess sludge directly from the reaction tank using the manure vehicle drawer, it is very difficult to draw sludge accumulated on the floor area evenly and the oxygen supply device installed in the lower part of the reactor due to the strong suction force There is a problem that a failure occurs by touching the diffuser, which may lower the function of the sewage treatment facility.

따라서, 미생물에 의한 오수처리 시설은 필연적으로 잉여슬러지가 발생되고 적정량의 슬러지는 필요에 따라 인발해 주어야 하는데, 방법에 따라 설치비용의 상승요인, 위생적인 문제, 기계장치의 고장 등 문제점을 개선할 필요성이 절실하다.Therefore, the microbial sewage treatment facility inevitably generates excess sludge and draws an appropriate amount of sludge as needed. According to the method, problems such as an increase in installation costs, hygienic problems, and mechanical failures may be improved. Need is desperate.

본 발명은 이와같은 종래의 제반 문제점을 최소화 하고자 연구, 개발 한 것으로서 다음과 같은 목적을 갖는다.The present invention has been researched and developed in order to minimize such problems in the related art, and has the following objectives.

본 발명의 주 목적은 오수의 정화처리시 발생되는 잉여슬러지를 반응조(처리수조) 에서 직접 인발 할 수 있도록 슬러지 인발장치를 반응조에 설치하여 분뇨차량 흡입구와 연결할 수 있도록 켐록커프링을 장착하므로서, 간편하게 필요량의 잉여슬러지를 인발할 수 있도록 개발하였다.The main object of the present invention is to install a sludge drawing device in the reaction tank so that the excess sludge generated during the purification process of sewage can be directly drawn out from the reaction tank (treated water tank), so that the chemlock cup ring can be easily connected to the intake port of the manure vehicle. It was developed to draw the required amount of excess sludge.

본 발명은 그 구조가 간단하고 제작이 용이하며 설치가 간편하여 제조원가를 크게 절감할 수 있도록 하였으며, 슬러지 인발은 쉽고 용이하게 개발하였다.The present invention is a simple structure, easy to manufacture and easy to install to greatly reduce the manufacturing cost, the sludge drawing was developed easily and easily.

본 발명은 반응조 내부 하단에 적절한 간격을 두어 설치하므로서 바닥 전면적에 쌓여있는 오래된 슬러지부터 균등하게 인발하는데 용이하다.The present invention is easy to draw evenly from the old sludge accumulated on the entire floor by installing a suitable interval at the bottom inside the reactor.

본 발명은 반응조의 용량에 따라 인발 할 수 있는 량을 조정할 수 있도록 인발관의 크기와 분뇨차의 흡입장치가 연결되게 조절할 수 있도록 개발하였다. (켐록커프링<36>의 구경 : 8cm , 6.5cm , 5cm , 4cm )The present invention has been developed so that the size of the draw tube and the suction device of the manure car can be connected to adjust the amount that can be drawn according to the capacity of the reactor. (Caliber of chemlock coupling <36>: 8cm, 6.5cm, 5cm, 4cm)

본 발명은 반응조에서 침전이 이루어지는 오수처리시설에서는 슬러지가 반응조하단 전면에 깔려있으므로 균등하게 슬러지를 인발할 수 있도록 200cm 간격마다 인발관을 설치하고, 인발관 하부에 200cm 간격으로 깔때기형 흡입장치를 장착하여 반경 100cm 이내의 슬러지를 모두 흡입할 수 있도록 개발하였다.In the present invention, in the sewage treatment facility where sedimentation takes place in the reaction tank, the sludge is laid on the front bottom of the reaction tank so that a drawing pipe is installed every 200 cm so that the sludge can be evenly drawn, and a funnel-type suction device is installed at the bottom of the drawing pipe at 200 cm intervals. It was developed to suck all sludge within a radius of 100cm.

이하 첨부된 도면에 의거하여 본 발명에 대한 다양한 실시예에 따라 상세히 살펴보기로 한다.Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

도 1은 오수처리 시설 중 반응조에 바람직한 설치방법을 보여주는 구성도이고,1 is a block diagram showing a preferred installation method in the reaction tank of the sewage treatment facility,

도 2는 슬러지를 흡입하는 깔때기형 흡입장치이며, 도 3은 본 발명품인 슬러지 인발관의 단면도이다.Figure 2 is a funnel-type suction device for sucking sludge, Figure 3 is a cross-sectional view of the sludge drawing tube of the present invention.

도 1과 같이 슬러지 인발 장치의 구조는 의외로 간편하고 설치가 용이하게 되어있다.As shown in Figure 1, the structure of the sludge drawing device is surprisingly simple and easy to install.

<31>,<32>,<33>은 인발관으로써 슬러지를 균등하게 인발하려면 최초 흡입장치부터 마지막에 설치되어 있는 흡입장치까지 동일한 흡입력을 구비해야 한다. 따라서, 인발관을 깔때기형 흡입장치의 흡입량에 따라 점차적으로 소구경 관을 사용함으로서 균등한 흡인력을 갖추게 하였다.<31>, <32>, and <33> should have the same suction force from the first suction device to the last installed suction device in order to draw sludge evenly as a drawing tube. Therefore, the drawing tube is provided with an even suction force by gradually using a small diameter tube according to the suction amount of the funnel-type suction device.

도 2의 흡입장치는 깔때기형 모형을 구성하여 수면하에 침전된 슬러지를 효과적으로 흡입할 수 있도록 하였고, 흡입장치의 흡입구멍<23>은 반경 100cm 주변의 슬러지를 흡입할 수 있도록 흡인력을 강화하기 위하여 깔때기 흡입량의 1/8 규격으로 깔때기 측 하면에 8개씩 설치하였다. 또한, 경사판<22>은 슬러지가 흡입장치위에 쌓이는 것을 방지하기 위하여 설치하였으며, 흡입시 흡입장치 위에 쌓인 슬러지가 경사판을 타고 흘러내려 고루 인발 될 수 있도록 하였다.The suction device of FIG. 2 constitutes a funnel type model to effectively suck the sludge settled under the water, and the suction hole <23> of the suction device has a funnel to enhance suction force so as to suck the sludge around a radius of 100 cm. 8 units were installed on the bottom side of the funnel with 1/8 standard suction capacity. In addition, the inclined plate <22> was installed to prevent the sludge from being accumulated on the suction device, so that the sludge accumulated on the suction device during the suction can flow down the inclined plate to be evenly drawn.

또한, 슬러지 인발은 주로 분뇨수거 차량을 이용하므로 장치의 흡입구<23>는 분뇨차량 흡입구와 연결할 수 있는 켐록 커프링의 용량 규격에 따라 설치하므로서 인발이 용이하게 하였다.In addition, since the sludge drawing mainly uses a manure collection vehicle, the suction inlet of the device is installed according to the capacity specification of the chemlock cuff ring that can be connected to the manure vehicle inlet, thereby making the drawing easy.

그리고, 분뇨차량을 이용하여 슬러지 인발시 흡인력으로 인발장치가 유동할 수 있기 때문에 반응조하단에 인발장치를 견고하게 고정할 수 있도록 고정장치<34>를 설치하였다.In addition, since the drawing device can flow with suction force when the sludge is drawn using the manure vehicle, a fixing device is installed to firmly fix the drawing device at the bottom of the reaction tank.

전체적으로 슬러지 인발장치는 도 1과 같이 반응조 내에 200cm간격으로 설치하여 반응조 하단에 침전된 슬러지를 균등하게 인발 할 수 있도록 하였으며, 깔때기형 흡입장치는 하단에 고정 설치하므로서 반경 100cm 내의 슬러지를 흡입할 수 있도록 하였다.Overall, the sludge drawing device was installed at 200cm intervals in the reaction tank as shown in FIG. It was.

따라서 슬러지 인발장치는 최초 오수처리시설과 동시에 기 설치함으로서 인발효율을 최대화하여야 한다.Therefore, the sludge drawing device should be installed at the same time as the first sewage treatment plant to maximize drawing efficiency.

이상과 같이 슬러지 인발 장치는 PVC 파이프관을 이용한 인발관과 깔때기형 흡입장치로 구성되어 전체적으로 볼 때 그 구조가 단순하고 제작이 용이하여 운용 방법이 간편하기 때문에 활용가치가 매우 우수하며, 반면에 제조원가를 크게 절감할수 있다. 또한, 기계 장치가 아니고 설비장치가 되므로 고장의 염려가 전혀 없을 뿐 아니라 필요시마다 적정량의 잉여슬러지를 균등하게 인발할 수 있는 우수한 효과를 갖고 있다.As mentioned above, the sludge drawing device is composed of a drawing pipe using a PVC pipe and a funnel type suction device, and as a whole, its structure is simple and it is easy to manufacture, and its operation method is very simple. Can greatly reduce the In addition, since it is not a mechanical device but a facility device, there is no fear of failure and it has an excellent effect of equally drawing out an appropriate amount of surplus sludge whenever necessary.

따라서 슬러지 저류에 필요한 저류장치, 저류된 슬러지 이송에 필요한 배관 장치, 저류된 슬러지의 부패로 인한 악취 발생등의 위생적인 문제, 슬러지 인발 시 기계적인 고장 , 불균등한 슬러지 인발로 박테리아의 생존 조건 위협등의 제반 문제점을 간단한 슬러지 인발장치로 해결할 수 있다.Therefore, hygienic problems such as storage equipment necessary for sludge storage, piping equipment necessary for transporting stored sludge, odor generation due to decay of stored sludge, mechanical failure when drawing sludge, threatening the survival condition of bacteria by uneven sludge drawing, etc. All the problems can be solved with a simple sludge drawing device.
