본 발명은 유입된 원수에 약품을 혼화하여 주는 혼화지에 관한 것으로, 특히 단일 혼화수조 내에서 유입된 원수를 2단계로 혼화되도록 하여서 혼화효율을 향상시켜 주는 상,하수처리장의 혼화지에 관한 것이다.The present invention relates to a mixed paper for mixing chemicals in the incoming raw water, and more particularly, to the mixed paper of the water and sewage treatment plant to improve the mixing efficiency by mixing the raw water introduced in a single mixed tank in two stages.

상,하수처리장의 혼화지는 유입되는 원수에 포함하고 있는 각종의 불순물이나 이물질이 응결되도록 하기 위해서 그 원수에 약품을 혼화하여 주는 수처리 공정을 감당하게 되는 바, 이러한 상,하수처리장의 혼화지는 원수에 약품을 혼합하는 방식에 따라 기계식과 2단혼화식으로 대별되어 있다.The mixing site of the water and sewage treatment plant undergoes a water treatment process in which chemicals are mixed into the raw water in order to condense various impurities and foreign substances contained in the incoming raw water. Depending on the way the drug is mixed, it is divided into mechanical and two-stage mixing.

기계식 상,하수처리장의 혼화지는 원수가 경유하도록 유입 및 유출구를 가지는 혼화수조와, 상기 혼화수조를 경유하는 원수에 약품을 투입하도록 설치되는 약품주입기와, 상기 혼화수조 내에서 약품과 원수가 혼화되도록 회전동작하는 임팰러를 갖는 혼합기로 구성되어 있다. 즉, 기계식 상,하수처리장의 혼화지는 유입구를 통하여 혼화수조 내에 유입된 원수에 약품주입기로 약품을 투입하고, 약품과 원수를 혼합기의 임팰러를 회전동작시켜서 혼화시킨 후 유출구를 통하여 응집지로 유출 시키게 되므로, 비교적 간단한 구조로서 원수에 약품을 혼화할 수 있는 장점을 가지게 되었다.The mixing site of the mechanical water and sewage treatment plant has a mixing tank having an inlet and an outlet through the raw water, a chemical injector installed to inject the chemical into the raw water passing through the mixing tank, and a mixture of the chemical and the raw water in the mixing tank. It is composed of a mixer having a rotating impeller. In other words, the mixing zone of the mechanical water and sewage treatment plant is introduced into the raw water introduced into the mixing tank through the inlet, and the chemical is injected into the chemical injector. Therefore, as a relatively simple structure has the advantage of mixing the drug into the raw water.

그러나, 이와 같은 기계식 상,하수처리장의 혼화지는 외부전원을 공급받아서 회전동작하는 임팰러를 갖는 혼합기에 의존하여 혼화수조 내의 약품과 원수를 물리적으로 혼화시키게 되는 점을 감안하여 볼 때, 약품과 원수의 혼화시간이 길어지고 약품의 투입량이 증가될 뿐만 아니라, 혼합기를 무리하게 운용하게 되어서 쉽게 고장이 발생되고 전기사용량이 증가되는 등의 문제점을 수반하게 되었다.However, in view of the fact that such mixed water in the water and sewage treatment plant is physically mixed with chemicals and raw water in the mixed water tank by relying on a mixer having an impeller rotating in response to external power. In addition, the mixing time is increased, and the amount of chemical input is increased, and the mixer is forcibly operated, which causes problems such as failure and easy use of electricity.

2단혼화식 상,하수처리장의 혼화지는 유입된 원수와 약품주입기로 투입된 약품이 화학적 반응으로 혼화되게 하여 1차 혼화수를 생성하는 혼화관로와, 상기 혼화관로의 후방에 연결되며 내부에 임팰러를 갖는 혼합기를 설치하여서 1차 혼화수를 다시 물리적 반응으로 혼화되게 하여 2차 혼화수를 생성하는 혼화수조로 구성되어 있다. 즉, 2단혼화식 상,하수처리장의 혼화지는 혼화관로에서 원수와 약품이 화학적 반응으로 혼화되게 하여 1차 혼화수를 생성하고, 1차 혼화수를 다시 혼화수조에서 임팰러를 갖는 혼합기로서 물리적 반응으로 혼화되게 하여 2차 혼화수를 생성하는 2단계의 혼화과정을 거치기 때문에, 원수와 약품의 혼화효율을 증대시켜서 혼화시간을 단축하고 약품의 소요량을 절감할 수 있게 하여 주면서도, 혼합기의 무리한 운용을 회피하여서 고장이 발생됨을 방지하여 주는 등의 장점을 가지게 되었다.The mixing stage of the two-stage mixed water and sewage treatment plant is mixed with the chemicals introduced into the raw water and the chemical injector by chemical reaction to produce a first mixed water, and is connected to the rear of the mixing pipe and the impeller inside It is comprised by the mixing tank which installs the mixing mixer which makes a primary mixed water mix again by physical reaction, and produces | generates a secondary mixed water. In other words, the mixing stage of the two-stage mixed phase and sewage treatment plant causes the raw water and the chemical to be mixed in the chemical mixing line by chemical reaction to generate the first mixed water, and the first mixed water is physically reacted as a mixer having impeller in the mixed water tank again. Because of the two stages of mixing process to generate the second mixed water by mixing with water, it is possible to reduce the mixing time and reduce the amount of chemicals while increasing the mixing efficiency of raw water and chemicals, By avoiding it has the advantage of preventing the occurrence of failures.

그러나, 이와 같은 2단혼화식 상,하수처리장의 혼화지는 2단계의 혼화과정을 수행하기 위하여 독립된 혼화관로와 혼화수조를 하나로 연결한 구조를 갖추고 있기 때문에, 그 혼화지 자체가 구조적으로 복잡하고 대형화되어서 설비면적 및 설비비용이 대폭적으로 증가되는 문제점이 있었다.However, because the mixed stage of the two-stage mixing type water and sewage treatment plant has a structure in which a separate mixing pipeline and a mixing tank are connected to perform a two-step mixing process, the mixed region itself is structurally complicated and enlarged. There was a problem that the facility area and equipment cost is significantly increased.

본 발명은 단일 혼화수조 내에서 원수와 약품을 2단계로 혼화하여 주도록 구성하여서, 첫째 원수와 약품의 혼화하는 능력이 우수한 상,하수처리장의 혼화지를 제공하는 데 목적이 있으며, 둘째 원수와 약품을 혼화하도록 설비하고 운용하는 데 따른 제반 여건을 획기적으로 개선시킨 상,하수처리장의 혼화지를 제공하는 데 목적이 있다.The present invention is configured to mix the raw water and the drug in two stages in a single mixed water tank, the first object is to provide a mixture of water and sewage treatment plants excellent in the ability to mix the raw water and the drug, the second raw water and the drug The purpose is to provide a mixed area for water and sewage treatment plants, which has drastically improved the conditions associated with the installation and operation of mixed facilities.

본 발명도 원수가 경유하도록 유입 및 유출구(11)(12)를 가지는 혼화수조(10)와, 상기 혼화수조(10)로 유입되는 원수에 약품을 투입하도록 설치되는 약품주입기(20)로 구성된 점에서는 종래의 것과 기술개념을 같이 한다.The present invention also consists of a mixed water tank (10) having inlet and outlet (11, 12) to feed the raw water, and a chemical injector (20) which is installed to inject the chemical into the raw water flowing into the mixed water tank (10) In the same concept as the conventional technology.

단, 본 발명의 상,하수처리장의 혼화지는 도 1 및 도 2에 도시되는 바와 같이, 상기 혼화수조(10) 내부에 상하로 유입 및 유출측 영역(B)(C)을 구획하도록 압출통로(A)가 형성된 구획벽(30)을 수평하게 설치하고, 상기 구획벽(30)의 상부에 압출통로(A)를 중심으로 월류관(40)을 수직으로 세워서 설치함을 기술구성상의 특징으로 한다.However, as shown in FIG. 1 and FIG. 2, the mixed paper of the water and sewage treatment plant of the present invention is divided into the inflow and outflow side regions (B) and (C) by the extrusion passage (C). A) formed partition wall 30 formed horizontally, and the upstream pipe 40 is installed vertically centered on the extrusion passage (A) in the upper portion of the partition wall 30 is characterized in the technical configuration. .

이와 같이 본 발명은 유입구(11)를 통과한 원수와 약품주입기(20)에서 투입 된 약품이 혼화수조(10) 내의 유입측 영역(B)에 유입되어 화학적 반응으로 1차로 혼화되고, 유입측 영역(B)에서 1차로 약품과 혼화된 원수는 구획벽(30)의 압출통로(A)를 통하여 수직방향으로 압력 분출되고 월류관(40)을 통하여 유출측 영역(C)으로 월류되면서 물리적 반응으로 2차로 혼화되게 하는 방식으로, 단일 혼화수조(10) 내에서 원수와 약품을 2단계로 혼화하여 주도록 구성함으로써, 첫째 유입된 원수와 약품의 혼화효율을 대폭적으로 향상시켜서 혼화시간을 단축하고 약품의 소요량을 절감할 수 있게 하여 주며, 둘째 단일 혼화수조로 소형화를 실현시켜서 설비면적과 설비비용을 최소화하여 주며, 셋째 혼합기의 무리한 운용을 회피하여서 고장이 발생됨을 방지하여 주는 동시에 전기사용량을 절감할 수 있게 하여 주는 등의 장점을 가지게 된다.As described above, in the present invention, the raw water passing through the inlet 11 and the medicine injected from the chemical injector 20 flow into the inlet side B in the mixed water tank 10 to be firstly mixed by the chemical reaction, and the inlet side region. In (B), the raw water admixed with the chemical is pressurized in the vertical direction through the extrusion passage A of the partition wall 30 and flows through the overflow pipe 40 to the outflow side region C as a physical reaction. In the second mixing method, the raw water and the chemicals are mixed in two stages in a single mixing tank 10. First, the mixing efficiency of the introduced raw water and the chemicals is greatly improved, thereby shortening the mixing time and Second, it can reduce the requirements, and secondly, miniaturization with a single mixed water tank minimizes the facility area and equipment cost. Third, it avoids excessive operation of the mixer and prevents the occurrence of failure. The advantages of which makes it possible to reduce electricity usage at is had.

As shown in FIG. 1, the partition wall 30 has an inlet side region B connected to the inlet 11 at the inner bottom of the mixed water tank 10 and an outlet side region associated with the outlet 12 at the upper portion thereof. (C) is partitioned so as to ensure that the raw water and the drug introduced through the inlet 11 is first mixed with the chemical reaction in the inlet region (B), the primary mixed water mixed with the raw water and the chemical is extruded Through the passage (A) to take the role of allowing the pressure to be ejected to the top.

본 실시예에서, 상기 구획벽(30)은 도 1 및 도 2의 도시와 같이, 상기 혼화수조(10)의 유입구(11)와 유출구(12) 사이의 벽체(10b) 내면에 격자형으로 수평하게 고정 설치되는 고정틀(31)로서 복수개의 막이판넬(32)들 및 중앙에 압출통로(A)가 형성된 1개의 통수판넬(33)이 수평하게 지지되도록 조립 설치하여서 된 것으로 예시되어 있다. 이러한 구획벽(30)은 고정틀(31)로서 막이판넬(32)들 및 통수판넬(33)이 지지되도록 조립한 구조로서, 구획벽 자체를 간편하고 견고하게 설치할 수 있는 이점을 갖는다.In the present embodiment, the partition wall 30 is horizontally latticed on the inner surface of the wall 10b between the inlet 11 and the outlet 12 of the mixed water tank 10, as shown in FIGS. 1 and 2.
