Abstract
기존의 약품응집침전에 의한 폐수처리공정에서는 폐수중에 있는 colloid성 물질과 용해성 물질이 잘 섞어지도록 하기 위하여 약품혼화조①에 응집제를 투입한 후 동력을 사용하여 급속교반하고, floc형성조②에서 floc이 잘 형성되도록 동력을 사용하여 완속교반하여 침전조③에서 floc이 침전제거될 수 있도록 하는 공정이나, 본 발명은 동력을 전혀 사용하지 않고 소음·진동도 없이 단지 침사조①과 약품혼화·floc형성관②와의 수위차 및 수평류를 40∼60°방향으로 지그재그형으로 자연유하하면서 약품혼화 및 floc형성이 동시에 일어나도록 하여 침전조③에거 형성된 floc이 침전제거될 수 있도록 하는 공정이다. 특히 본 발명의 주요부분인 약품혼화·.FLOC형성관②에서는 동력이 전혀 사용되지 않으며 처리시간이 단축되므로 설치비용이 적게 들고 유지관리비가 거의 안 들고 처리효율이 그게 향상되므로 경제적인 처리방법이다.In the wastewater treatment process by the conventional coagulation sedimentation, the coagulant is added to the chemical admixture ① to stir the colloid material and the soluble substance in the wastewater, and the mixture is rapidly stirred using the power, and the floc The floc can be precipitated and removed from the sedimentation tank ③ by using the power to make it well. However, the present invention is a process in which no power is used, (2) and the horizontal flows are naturally flown in a zigzag fashion in the direction of 40 to 60 °, while allowing drug mixing and floc formation to occur simultaneously so that the floc formed in the precipitation tank (3) can be precipitated and removed. Particularly, it is an economical treatment method since the power is not used at all, and the treatment time is shortened, the installation cost is reduced, the maintenance cost is reduced, and the treatment efficiency is improved.

제2도는 본 발명에서 고안한 폐수처리 공정도.FIG. 2 is a process chart of a wastewater treatment system devised in the present invention. FIG.
제3도는 본 발명에서 고안한 약품혼화·floc형성관의 상세도.FIG. 3 is a detailed view of a drug mixing / floc forming tube devised in the present invention.
본 발명은 유기질 또는 무기질의 colloid狀 입자를 함유하는 폐수를 구형관로로 흐르게 하고, 관로의 유입구에다는 적정량의 응집제를 투입시겨 floc을 형성·침전처리 하는 방법에 관한 것으로 특히, 수위차에 의한 자연유하식 수평류 흐름으로 유도하고 지그재그식으로 흐르게 하며, 이 관로의 흐름과정에서 유기질 또는 무기질 colloid狀 입자와 응집제가 혼화돔과 동시에 형성된floc이 관로내에는 침전되지 않고 서서히 침전조를 향햐여 점차로 floc이 크게 형성되어 가면서 관로를 이송되도록 한 처리효율이 큰 경제적 처리방법에 관한 것이다.The present invention relates to a method of flowing wastewater containing organic or inorganic colloidal particles into a spherical channel and forming and depositing floc by adding an appropriate amount of coagulant to the inlet of the channel, The floc, which is formed by organic or inorganic colloidal particles and coagulant at the same time as the mixing dome, is not precipitated in the channel but gradually flows into the flocculent And the pipeline is transferred while being greatly formed.
본 발명은 동력을 사용하거나 진동도 없이 단지 수위차 및 약품혼화·floc형성관②내를 유기질 또는 무기질의 colloid狀 입자를 함유하는 폐수가 자연유하에 의해 지그재그형으로 흐르도록 한 경제적인 처리방법이다.The present invention is an economical treatment method in which wastewater containing organic or inorganic colloidal particles flows in a zigzag manner by natural flow without using power or vibration, .
본 발명은 제1도와 같은 기존의 약품응집침전 폐수처리공정에 대한 결점을 보완하고 폐수의 특성을 고려한 새로운 처리방법으로써, 제2도에서 약품혼화·floc형성관②앞부분에 침사조①를 설치하여 응집제의 양을 줄이고, 직사각형, 정사각형 또는 원형의 단면을 가진 약품혼화·floc형성관②의 입구에서 응집제를 투입하고 침사조①과 약품혼화·floc형성관②와 일정한 수위차를 두고 上下流가 아닌 수평류의 40∼60°방향, 즉 지그재그형으로 흐르도록 한 폐수의 처리방법이다.The present invention is a new treatment method that compensates for the drawbacks of the conventional coagulation sedimentation wastewater treatment process of the first aspect and takes into consideration the characteristics of the wastewater. In the second step, the sedimentation tank 1 is installed at the front part of the drug- Mixing agent with rectangular, square or circular cross section and injecting coagulant at the inlet of floc forming tube ② and mixing with sedimentation tank ① and drug mixing · floc forming tube ②, In a direction of 40 to 60 占 of horizontal flow, that is, in a staggered manner.
제1도와 같은 기존의 약품응집침전 폐수처리공정에서는 폐수중에 있는 colloid성물질과 용해성 물질이 잘 섞어지도록 약품혼화조①에 응집제를 투입한 후 동력을 사용하여 급속교반하고, floc형성조②에서 floc이 잘 형성되도록 동력을 사용하여 완속교반하고 침전조③에서 floc이 침전제거될 수 있도록 하는 공정이다. 그러나 제2도의 본 발명은 동력을 전혀 사용하지 않고 소음·진동도 없이 단지 침사조①과 약품혼화·floc형성관②와의 수위차 및 수평류를 40∼60°방향으로 자연유하하면서 약품혼화 및 floc형성이 동시에 일어나도록 하여 침전조③에서 형성된 floc이 침전제거될 수 있도록 하는 공정이다.In the conventional chemical coagulation sedimentation wastewater treatment process as shown in FIG. 1, the coagulant is added to the chemical admixture tank 1 so that the colloid substance and the soluble substance in the wastewater can be mixed well, and then rapidly stirred using the power, And the floc is precipitated and removed from the precipitation tank ③. However, according to the present invention of FIG. 2, the water level difference and the horizontal flow between the settling tank 1 and the chemical admixture / floc forming tube 2 are naturally flowed in the direction of 40 to 60 ° without any power, So that the floc formed in the settling tank 3 can be precipitated and removed.
악품혼화·floc형성관②의 상세도는 상하류 흐름을 수평류 흐름으로 바꾸고 관속에서 지그재그로 흐르도록 고안한 제3도와 같은 모형이다. 처리방법의 흐름과정에 있어, 침사조①은 세모래나 쇳가루와 같은 무기성 물질을 침전시키므로 관 입구에서 응집제를 적게 투입할 수 있도록 하기 위한 공정이다. 침사조①에서 약품혼화·floc형성관②로 유입되는 관의 입구에 주입된 응집제은 관속에서 지그재그형으로 흐르면서 폐수중에 있는 colloid성 물질과 용해성 물질과의 접촉혼합을 높이고 floc이 깨지지 않고 점점 커지면서 질 형성되어 침전조③에서 Wkgq은 시간내에 침전된다. 본 발명에서 폐수의 흐름 방향을 上下流로 하지 않고 수평류의 40∼60°방향으로 한 이유는 上下流로 하면, floc이 침전조③에 도달하기도 전에 약품혼화·floc형성관② 속에서 침전물이 가라앉으므로 관이 막히기 때문이다.The details of the mixer / floc-forming tube (2) are the same model as the third flow chart, which is designed to flow the upstream and downstream flows into horizontal flow and flow from the vortex to the zig-zag. In the course of the treatment process, the sedimentation tank ① is a process for depositing inorganic substances such as three sands or flour, so that less coagulant can be injected at the entrance of the pipe. The coagulant injected into the inlet of the pipe flowing into the chemical admixture / floc forming tube (2) in the stinging tank (1) flows in a zigzag form in the tube to increase the contact mixing between the colloidal substance and the soluble substance in the wastewater, In the settling tank ③, Wkgq is precipitated in time. In the present invention, the flow direction of the wastewater is not in the upstream and downstream directions but in the direction of 40 to 60 degrees in the horizontal flow. When the floc reaches the settling tank ③, the sediment flows in the floc- It is because the tube is clogged because it seats.
본 발명의 주요부분인 무동력 약품혼화·floc형성관②은 처리시간이 단축되므로 설치비용이 적게 들고 유지관리비가 거의 안들고 처리효율이 크게 향상되므로 경제적인 처리방법이다.As a main part of the present invention, the non-powered chemical admixture / floc forming tube (2) is an economical treatment method because the treatment time is shortened, the installation cost is low, the maintenance cost is low and the treatment efficiency is greatly improved.
