Stirring impeller 6 is installed in the middle portion of (3), the sludge circulation pump (4) is installed at the bottom, and the raw water inlet pipe (8) is installed in the coagulation reaction chamber (2), A raw water inlet 8-1 and a chemical inlet 8-2 are formed at the front end, and a treated water outlet 10 is provided at an upper side of the settling chamber 1-2, and a partition wall 1-1 is provided inside. Inflow path (9) is formed through the, one side of the lower sludge outlet 11 is installed.

이상과 같이 구성된 본 발명은 각종 처리수 속에 함유된 슬러지를 급속 처리하는데 주로 사용되는 슬러지 순환형 급속 침전 장치인 바 이를 실시할 시는 원수 유입구(8-1) 및 약품 주입구(8-2)가 있는 원수 유입관(8)을 통해 응집 반응실(2)에 슬러지 원수를 유입시키면 모터(5) 및 감속기(5-1)에 의해 회동되는 교반용 임팰러(6)에 의해 슬러지 원수는 상승되어진 후 유입로(9)를 통해 침전실(1-2) 내로 유입된다. 이때, 비중이 무거운 응축된 슬러지는 하강하고 비중이 가벼운 물은 분리되어 상승한다. 그리고, 슬러지 농축부(7)에 모아진 고농도 슬러지는 슬러지 순환펌프(4)에 의하여 흡입된 후 상부로 순환되어 응집 반응실(2)로 이송되어진다. 이때, 원수 유입관(8)의 유입구(8-1) 및 약품 주입구(8-2)로 유입 된 슬러지 원수와 약품은 슬러지 순환 펌프(4)에 의해 하부에서 순환 상승된 응축된 슬러지와 함께 접촉, 흡착 및 응집 등의 반응이 일어나서, 보다 큰 응집물이 생성된다.The present invention configured as described above is a sludge circulation type rapid sedimentation apparatus mainly used for rapid treatment of sludge contained in various treated water. At the time of performing the raw water inlet 8-1 and the chemical inlet 8-2, When the sludge raw water is introduced into the coagulation reaction chamber 2 through the raw water inlet pipe 8, the sludge raw water is raised by the stirring impeller 6 rotated by the motor 5 and the reducer 5-1. After the inflow path (9) is introduced into the settling chamber (1-2). At this time, the condensed sludge with heavy gravity falls and the lighter gravity is separated and rises. Then, the high concentration sludge collected in the sludge thickening unit 7 is sucked by the sludge circulation pump 4 and then circulated to the upper part and transferred to the coagulation reaction chamber 2. At this time, the sludge raw water and the chemical introduced into the inlet 8-1 and the chemical inlet 8-2 of the raw water inlet tube 8 is in contact with the condensed sludge circulated from the bottom by the sludge circulation pump 4 Reactions such as adsorption and aggregation occur to produce larger aggregates.

이와 같이 생성된 응집물은 슬러지 순환 펌프(4)에 의해 응집 반응실(2)의 상부로 올라가서 응집 반응실(2)과 격벽(1-1) 사이에 형성된 유입로(9)를 통해 침전실(1-2) 내로 하강된다. 이때, 유입된 응집물은 상기한 바와 같이 침전실(1-2) 내에서 비중의 차이에 의하여 분리된 분리수는 상부로 모이게 되고, 비중이 무거운 응집물은 하부로 침전 분리되어 진다.The aggregate produced in this way is raised to the upper part of the flocculation reaction chamber 2 by the sludge circulation pump 4 and is settled through the inlet path 9 formed between the flocculation reaction chamber 2 and the partition wall 1-1. 1-2) descend into. At this time, the introduced aggregate is separated by the difference in specific gravity in the settling chamber (1-2), as described above, the separated water is collected at the top, and the heavy aggregate is precipitated and separated at the bottom.

하부로 침전된 응집물은 슬러지 농축부(7)에 모여서 농축되어 진다. 이때, 하부로 모아진 농축 슬러지는 재차 슬러지 순환 펌프(4)에 의하여 응집 반응실(2) 내로 순환하여 외부에서 유입되는 슬러지 원수와 재 접촉하여 보다 큰 응집물로 응집되기 때문에 응집 효율을 더욱 증대시킨다.The aggregate precipitated to the bottom is concentrated in the sludge concentration unit (7). At this time, the concentrated sludge collected to the lower side is circulated again by the sludge circulation pump 4 into the coagulation reaction chamber 2, and re-contacts with the sludge raw water introduced from the outside to agglomerate into larger aggregates, thereby further increasing the coagulation efficiency.

그리고, 침전실(1-2)에서 분리된 깨끗한 물은 상부로 올라가서 웨어(10-1)를 통하여 처리수 배출구(10)로 배출되고, 침전실(1-2)에서 침전된 응집물(슬러지)은 슬러지 농축부(7)에서 농축되어 응집되는 것이나, 응집된 슬러지량이 증대되어 침전실(1-2) 내부에서 슬러지층(7-1)이 증가하게 되면, 이때에는 침전실(1-2)내에서의 응집물과 물의 분리가 어려워지므로 이때에는 하부의 슬러지 배출구(11)를 통하여 슬러지를 외부로 배출시켜야 한다. 슬러지 배출구(11)를 통한 슬러지의 배출 수단으로는 밸브를 부착하여 수동으로 배출하거나 자동 밸브에 의한 자동 배출도 가능하며 자동 배출 시에는 타이머(Timer)에 의한 방법과 상부의 슬러지층(7-1)의 레벨에 의한 측정으로도 배출이 가능하다.Then, the clean water separated from the settling chamber (1-2) is raised to the upper portion and discharged to the treated water outlet (10) through the weir (10-1), aggregates (sludge) precipitated in the settling chamber (1-2) The silver is concentrated in the sludge thickening unit 7 and agglomerated, but when the amount of aggregated sludge increases and the sludge layer 7-1 increases in the precipitation chamber 1-2, the precipitation chamber 1-2 at this time. Since it becomes difficult to separate the condensate and the water therein, the sludge should be discharged to the outside through the sludge outlet 11 at the bottom. As a means of discharging the sludge through the sludge discharge port 11, it is possible to discharge it manually by attaching a valve or automatically discharge it by an automatic valve.In the case of automatic discharge, a method by a timer and an upper sludge layer 7-1 Emissions can also be achieved by measuring the level of).

그리고, 본 발명은 종래처럼 침전조 몸체(1)의 외부에 별도의 슬러지 순환펌프를장착하지 않고도 침전조 몸체(1) 내부에 모터(5) 및 감속기(5-1)의 단일 회전축(3)에 교반용 임펠러(6)와 슬러지 순환펌프(4)를 설치하여 슬러지를 내부에서 연속 순환 응집시킬 수 있도록 하였기 때문에 콤펙트(compact)화가 가능하여 설치 면적과 설치비 및 운영비의 절감을 할 수 있는 것이다.In addition, the present invention is agitated on the single rotating shaft (3) of the motor (5) and the reducer (5-1) inside the sedimentation tank body (1) without installing a separate sludge circulation pump on the outside of the sedimentation tank body (1) as in the prior art. Since the impeller 6 and the sludge circulation pump 4 are installed to allow the sludge to be continuously circulated and aggregated in the interior, it is possible to compact and reduce the installation area, installation cost, and operation cost.

이상과 같이 본 발명은 침전조 몸체(1) 내부에 슬러지 농축부(7)와 응집 반응실(2) 및 모터(5) 및 감속기(5-1)와 연결된 회전축(3)에 교반용 임팰러(6)와 슬러지 순환 펌프(4)를 설치함으로서 응집 및 농축 효율을 극대화 하였을 뿐만 아니라, 콤팩트화 할 수 있게 하였기 때문에 약품비, 운영비, 소요 부지, 시설비 등의 절감효과가 있고, 또한 이는 정수 처리, 폐수처리 뿐만 아니라 오수 및 하수 처리 등에도 적용이 가능하여 매우 유용한 발명이다.As described above, the present invention provides a stirring impeller (7) to the sludge concentration unit (7) and the coagulation reaction chamber (2) and the rotating shaft (3) connected to the motor (5) and the reducer (5-1) inside the sedimentation tank body (1). 6) and the sludge circulation pump (4) not only maximized the coagulation and concentration efficiency, but also made it compact, which can reduce the chemical cost, operating cost, required site, facility cost, etc. It is a very useful invention because it can be applied not only to treatment but also to sewage and sewage treatment.
