Description

수처리용 약품 교반 혼입장치{Chemicals agitation apparatus for water treatment}Chemical stirring agitation apparatus for water treatment {Chemicals agitation apparatus for water treatment}

본 발명은 수처리용 약품 교반 혼입장치에 관한 것으로, 더욱 상세하게는 교반 혼입조 내에 공급 저수된 폐수에 슬러지를 응집하는 처리약품인 응집제를 정량 공급하고, 이들을 교반 혼입하여 폐수에 포함된 슬러지가 응집되도록 한 수처리용 약품 교반 혼입장치에 관한 것이다.The present invention relates to a chemical stirring mixing device for water treatment, and more particularly, to supply a fixed amount of flocculant, which is a treatment chemical that aggregates sludge in the wastewater stored in the stirring mixing tank, and to mix and mix these sludge in the wastewater. It relates to a chemical stirring mixing device for water treatment.

일반적으로 폐수에는 다양한 오염물질이 포함되며, 그 중 인(P)을 함유하고 있는 폐수는 질산염이나 유기물을 포함하고 있다.In general, wastewater contains various contaminants, and wastewater containing phosphorus (P) contains nitrates or organic matter.

상기 폐수는 하수도로 집수된 후 정수장에서 정수 처리되어 상수도를 통해 재활용되고 있으며, 폐수 중에 함유되어 있는 오염물질의 제거방법으로는 생물학적 처리방법과 물리화학적 처리방법이 활용된다.The wastewater is collected into sewage and is purified through a water treatment plant and recycled through tap water. Biological treatment and physicochemical treatment are used as a method of removing contaminants contained in the wastewater.

여기서, 상기 생물학적 처리방법은 미생물이 혐기상태와 호기상태를 오가면서 오염물질의 방출과 흡수를 통하여 슬러지를 인출함으로써 오염물질을 제거하는 방법이고, 물리화학적 처리방법은 응집 침전법을 이용하여 오염물질을 제거하는 방법이다.Here, the biological treatment method is a method for removing contaminants by drawing sludge through the release and absorption of contaminants while the microorganism is going between anaerobic and aerobic states, and the physicochemical treatment method is a contaminant using a coagulation precipitation method. How to remove it.

한편, 본 발명과 관련하여 물리화화적 처리방법은 처리를 요하는 폐수에 처리약품인 응집제를 정량 투입한 다음 이를 교반 혼입하여서, 폐수 내에 잔류된 슬러지를 응집하여 처리하도록 응집 처리기법이 활용되고 있다.On the other hand, in the physicochemical treatment method in connection with the present invention, a flocculation agent, which is a treatment chemical, is quantitatively added to the wastewater requiring treatment, and then mixed with the agitation, and the flocculation treatment technique is utilized to aggregate and treat the sludge remaining in the wastewater. .

상기 응집 처리기법은, 교반 혼입조 내에 저수된 폐수에, 정량 공급펌프가 응집제를 정량 공급한 다음, 상기 혼입 교반 혼입조 내에 임펠러가 회전하면서 폐수와 응집제를 교반 혼입하도록 구성된다.The flocculation treatment method is configured such that a fixed-quantity supply pump quantitatively supplies a flocculant to the wastewater stored in the stirring mixing tank, and then stirs and mixes the wastewater and the flocculant while the impeller rotates in the mixing stirring mixing tank.

이와 같이 임펠러를 회전시켜 교반 혼입조 내에 저수된 폐수와 처리약품인 응집제를 교반 혼입하면, 폐수와 응집제의 교반 혼입 효율이 증대되는 이점을 갖는다. As such, when the impeller is rotated to stir and mix the wastewater stored in the stirring mixing tank and the flocculant which is a treatment chemical, the stirring mixing efficiency of the wastewater and the flocculant is increased.

그러나, 종래 임펠라를 포함하는 교반부는 단순히 전동모터로부터 회전력을 제공받아 일방향으로 회전하며, 교반 혼입조 내에 직립된 회전축에 임펠러를 고정한 형태로 이루어진다.However, the stirring part including the conventional impeller simply rotates in one direction by receiving a rotational force from the electric motor, and is formed in a form in which the impeller is fixed to a rotating shaft standing upright in the mixing mixing tank.

따라서, 종래 교반부는 항시 일정한 위치에 회전하는 임펠러에 의해 폐수와 응집제를 교반하도록 구성된 관계로, 교반 혼입조 내 사각구역에 위치한 폐수는 응집제와 제대로 혼입되지 아니한다.Therefore, the conventional agitator is always configured to agitate the wastewater and the flocculant by means of an impeller rotating at a constant position, so that the wastewater located in the square section in the stirring mixing tank is not mixed with the flocculant properly.

그리고, 응집된 슬러지에 의해 폐수와 처리약품인 응집제가 혼입된 혼입물의 유동성이 저하되어서, 저수된 폐수와 응집제의 균질화된 교반 혼입을 기대하기 어려웠다.The flocculated sludge lowered the fluidity of the mixture in which the wastewater and the coagulant as the treatment agent were mixed, and it was difficult to expect a homogenized mixing of the stored wastewater and the flocculant.

그리하여, 종래 상기 임펠러 자체의 회전만으로 생성된 교반 혼입력은 폐수와 응집제를 균질화되게 혼입하기에는 역부족이였다.Thus, the stirring mixing input generated only by the rotation of the impeller itself in the past was insufficient to homogeneously mix wastewater and flocculant.
