Dispersing and dispensing the chemicals in the mixing tube to be transported, and by mixing the chemicals by rotating the impeller at high speed by the rotation of the hollow shaft, the chemicals are uniformly dispersed and mixed to improve the reaction efficiency and do not overuse the drug. Prevents to reduce the amount of use, and in particular to the chemical dispensing in-line mixing device that can be installed in a narrow space, as well as easy to maintain and maintain the combination of the input and mixing process of the drug at the same time.

일반적으로 하수처리장 또는 폐수처리장의 목적은 오염된 물을 정수하여 수질을 높이는 것으로서, 오염된 물을 정수하는 방법은 물에 함유된 고형물질을 물로부터 분리 제거하는 것이며, 정수과정은 하수 또는 폐수에 약품(응집제)을 혼합하 여 반응시킨 다음, 응집과정 및 여과과정을 거친 후 정수된 물은 방류되고, 여기서 침전된 슬러지(sludge)는 탈수과정을 거친 후, 쓰레기 매립장에서 매립되거나 또는 소각장에서 소각처리 된다.In general, the purpose of a sewage treatment plant or wastewater treatment plant is to improve the water quality by purifying the contaminated water, and the method of purifying the contaminated water is to separate and remove the solid matter contained in the water from the water, and After mixing and reacting the chemicals (coagulant), the purified water is discharged after the coagulation process and the filtration process, and the sludge precipitated is dewatered and then landfilled or incinerated in an incineration plant. Is processed.

침전된 슬러지는 보통 95~98%의 수분을 함유하고 있으므로 수분을 최대한 분리 제거한 다음, 매립장이나 소각장에서 매립 또는 소각 처리하며, 통상 슬러지에서 수분을 분리 제거하기 위하여 사용되는 슬러지 탈수기는 벨트 프레스, 필터 프레스, 원심 분리기 및 진공 여과기 등이 적용되고 있다.Precipitated sludge usually contains 95 ~ 98% of water, so the water is separated and removed as much as possible, and then landfilled or incinerated in a landfill or incinerator, and a sludge dehydrator is usually used to separate and remove water from sludge. Presses, centrifuges and vacuum filters are applied.

종래 하수처리장 또는 폐수처리장에서 하수나 폐수에 약품(응집제)을 투입하는 방법은 디퍼(Dipper)식, 정량펌프식, 유량투입식 등으로 반응조(혼화조)의 수표면에 약품을 투입하여 물과 약품이 효율적으로 혼합되어 후속공정이 원활하게 진행될 수 있도록 기계적 혼화방식을 채택하고 있다.Conventional methods of adding chemicals (coagulants) to sewage or wastewater in sewage treatment plants or wastewater treatment plants include dipper, metering pump, and flow input methods to inject chemicals into the water surface of the reaction tank (mixing tank). The mechanical mixing method is adopted so that the chemicals can be efficiently mixed and the subsequent process can be smoothly performed.

그러나, 종래의 약품 투입방식은 별도의 반응조(혼화조)가 필요하므로 설치공간과 시설비가 과다하게 소요되고, 하수 또는 폐수와 약품의 혼화효율이 극도로 낮아져 약품과 관리비가 증가하는 한편 중화 또는 응집반응이 효율적이지 못하여 약품을 추가적으로 투입해야 하는 등 전반적으로 문제점이 있었다.However, since the conventional chemical input method requires a separate reaction tank (mixing tank), the installation space and facility cost are excessively increased, and the mixing efficiency of sewage or waste water and chemical is extremely low, which increases the chemical and management cost while neutralizing or coagulating. There was a problem in general, such as the need to add an additional drug because the reaction is not efficient.

따라서, 최근에는 침전조와 반응조 사이에 연결 설치된 이송배관에 약품을 정량으로 펌핑하여 투여하는 약품 분사파이프와, 투여된 약품과 폐수를 혼합 교반하는 교반날개를 각각 설치함으로써, 약품을 일정한 양으로 정량 투입하고, 약품과 폐수의 중화 또는 응집반응이 안정적이고 고효율적으로 실시되는 선행기술로서, 등록실용신안 제20-0439471호(약품 자동투입 및 혼화장치)가 제안된 바 있다.Therefore, recently, a chemical injection pipe for quantitatively pumping and administering a drug in a transport pipe installed between a settling tank and a reaction tank and a stirring blade for mixing and stirring the administered drug and waste water, respectively, are used to quantitatively input the chemical in a fixed amount. In addition, as a prior art in which the neutralization or flocculation reaction of chemicals and wastewater is carried out stably and efficiently, the Korean Utility Model Registration No. 20-0439471 (a drug auto-injection and admixture) has been proposed.

After the stirring blades are installed to mix the medicine evenly, the chemicals are injected and injected into the conveying pipe from which the waste water is transferred from the sedimentation tank to the reaction tank, and the stirring blade rotates to neutralize or aggregate the waste water as the waste water and the medicine are evenly mixed. The reaction is carried out stably and with high efficiency.

그러나, 상기의 선행기술은 침전조에서 반응조로 폐수가 이송되는 이송배관 안에 약품을 정량 분사하여 투입하는 약품 분사파이프와, 모터의 구동력으로 회전하여 약품을 골고루 혼합하는 교반날개가 각각 별도로 설치됨에 따라 설치공간이 넓게 필요하므로 협소한 공간에서는 설치가 어렵고, 작업시간이 오래 걸리는 한편 설치비가 과다하게 소요되는 실정이다.However, the prior art is a chemical injection pipe for quantitatively injecting the chemicals into the transport pipe transporting the waste water from the sedimentation tank to the reaction tank, and the stirring blades for mixing the chemicals evenly by rotating the driving force of the motor is installed separately It is difficult to install in a narrow space because the space is necessary, and it takes a long time and excessive installation cost.
