Abstract
Description
본 발명은 수중에 존재하는 현탁물질을 포함한 제반물질을 제거하기 위한 장치에 관한 것으로, 특히 수중에 포함된 현탁물질을 부유시켜 효과적으로 제거할 뿐 아니라, 현탁물질이 제거된 후에 산화 및 저류기능을 실행하여 유기물질의 분해 또는 수용성 금속이온을 산화할 수 있도록 한 현탁물질제거 및 난분해성 물질제거장치에 관한 것이다.The present invention relates to an apparatus for removing various substances including suspended substances present in water, and particularly, to suspend suspended substances contained in water to effectively remove them, and to perform oxidation and storage functions after the suspended substances are removed. The present invention relates to a device for removing suspended solids and hardly decomposable substances, which enables decomposition of organic substances or oxidation of water-soluble metal ions.
일반적으로 생활용수나 농업용수등으로 사용된 후 배수되는 각종 오폐수는 하천을 오염시키는 주원인이 되므로, 이를 정화하기 위한 많은 노력이 있어왔다.In general, various wastewaters that are drained after being used as living water or agricultural water are the main causes of polluting rivers, and thus many efforts have been made to purify them.
종래의 장치는 수중에서 현탁물질제거를 위하여 응집후에 침전과 여과수단 및 부상이나 여과수단으로 행해졌으며, 특히 침전후 여과수단에 있어 이를 단일체로 구성하고자하는 노력이 많이 있었으나, 침강속도와 여과유속등의 차이로 단일체 구성에 있어 복잡하고 제작설치비용등이 현실성이 없으므로 실용화되지 못하였다. 또한 부상과 여과수단에 있어서는 단일체 구성의 고안이 주목을 받았으나 부상분리후 일부 미세하고도 미분리된 이물질을 여과하기 위한 여과계통중 충분한 역세척이 이루어지지 않아 그 여과기능이 둔화되기 때문에 이를 위해서 여재충진실을 여러개로 구획분리하여 순차적으로 여재층 상부에서 불순물을 흡입제거하는 방식을 고안한 경우가 있었다.Conventional apparatus has been performed by sedimentation and filtration means after flocculation and flotation or filtration means to remove suspended substances in water. Especially, in the filtration means after sedimentation, there have been many efforts to construct it as a single body. Due to the difference, it is not practical because it is complicated in unitary construction and the manufacturing cost is not real. In the case of flotation and filtration means, the design of a monolithic structure was attracting attention, but since the filtration function is slowed down due to insufficient back washing in the filtration system for filtering some fine and unseparated foreign matter after flotation, In some cases, the filling chamber was divided into several sections and a method of sequentially removing suction from the upper portion of the filter layer was devised.
그러나, 이러한 경우에도 불순물을 흡입하는데 따른 충진된 여재의 상승을 동반하게 되고 이와함께 여재층 하부의 집수실로부터 여과된 물의 역세척용수로서의 사용은 필수적인 것이다. 아울러, 여재층이 팽창하여 불순물과 분리되기 위해서는 원수 여과유속에 비해서 역세유속은 3∼6배 정도의 유속이 필요하게 되고 여러개로 구획된 여재층의 한곳이라도 이러한 작업이 진행될때는 집수실에 모아지는 처리수의 생산량이 감소할 수 밖에 없으므로 여재충진시의 구획분리 역세척은 이상적인 방법이 되지 못했었다.However, even in this case, it is accompanied by an increase in the filled media by suctioning the impurities, and together with this, the use of the filtered water from the collection chamber below the media layer is essential for backwashing. In addition, in order for the median layer to expand and separate from impurities, the backwashing velocity is required to be about 3 to 6 times higher than that of the raw water filtration flow rate. As the yield of treated water was inevitably reduced, compartmentalized backwashing during filling was not an ideal method.
또한, 종래에 개발된 것으로서, 본원인에 의하여 선출원된 실용신안등록출원 제 97-79호의 '현탁물질제거장치'가 있으며, 이는 이물질 응집수단과 이물질침전 및 부유수거수단과 여과수단과 역세척수단으로 구성된 것으로서, 원수로부터 이물질을 응집시킨 후 부유되게하므로 정화효율이 양호하나, 이물질이 제거된 원수를 재처리하기 위하여는 별개의 장치가 필요하였다. 즉, 상기 일차적 처리로써 미흡한 1차처리수를 재차 분해 또는 산화처리를 정화하기 위하여 산화 및 저류공정을 거쳐야 하나, 이러한 다음 공정을 위하여 별개의 장치로 이동되어야 하기 때문에 단위면적당 작업효율이 저하되는 원인이 되었다.In addition, as a conventionally developed, there is a 'suspension material removal device' of the utility model registration application No. 97-79 filed by the applicant, which is a foreign matter agglomeration means, foreign matter sedimentation and flotation means, filtration means and backwash means It is composed of, the flocculation of the foreign matter from the raw water to be suspended, so the purification efficiency is good, but a separate device was required to reprocess the raw water from which the foreign matter was removed. That is, the primary treatment water that is insufficient as the primary treatment must undergo an oxidation and storage process in order to decompose or purify the oxidation treatment again, but the work efficiency per unit area decreases because it must be moved to a separate device for the next process. It became.
본 발명은 상기한 문제를 해결하기 위하여 연구개발된 것으로서, 원수에 함유된 이물질을 응집시킨후에 부유되게 하므로서 응집물의 제거가 신속하게 이루어지므로 결국 정화효율이 상승되도록 하는데 기술적 과제가 있다.The present invention has been researched and developed in order to solve the above-mentioned problems, there is a technical problem to increase the purification efficiency in the end because the removal of the aggregates is made quickly by flocculating the foreign substances contained in the raw water.
본 발명의 다른 기술적 과제는 일차적으로 이물질이 제거된 1차처리수를 별개의 장치로 이동시키지 아니하고 하나의 장치에서 산화 및 저류작용이 이루어지도록 하므로서 단위면적당 정화효율이 상승되도록 하는데 있다.Another technical problem of the present invention is to increase the purification efficiency per unit area by performing oxidation and storage in one device without first moving the primary treated water from which foreign substances are removed to a separate device.

또한, 상기 응집물부유실(3)의 상부측에 모타(10a)에 의하여 회동되는 부유물제거판(10b)을 장치한다.In addition, a floating matter removing plate 10b that is rotated by the motor 10a is provided on the upper side of the aggregate flotation chamber 3.
미설명부호 11은 유입관, 12믹서기, 13배출관 14는 산화용 기체분사기이다.Reference numeral 11 denotes an inlet tube, a 12 mixer, and an outlet tube 14 denote an gas injector for oxidation.
본 발명의 실시예로서, 도 2 에 도시된 바와 같이 소형일 경우에는 기포분사기(5a) 상부로 중앙부상분리관(21)을 별개로 설치하고 중앙부상분리관(21)내측 상부에서 저류 및 산화실(6)로 관통되는 청정수 유출관(22)을 장치하며, 분리격막(1c)과 부유물제거판(10b)를 장치하지 않는다.As an embodiment of the present invention, in the case of the small size as shown in Figure 2 is installed separately the central floatation tube 21 above the bubble injector (5a) and the storage and oxidation in the upper portion inside the central float separation tube 21 The clean water outflow pipe 22 penetrates into the seal 6, and the separation membrane 1c and the float removing plate 10b are not provided.
이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
오폐수가 유입관(11)을 거쳐 혼화기(4)를 통하여 이물질응집실(2) 내부로 유입되며, 이때 유입관(11)에 응집용약품과 중화용약품이 투입되고 믹서기(12)에서 혼합된후 이물질응집실(2)로 함께 유입된다.Waste water is introduced into the foreign matter agglomeration chamber (2) through the mixer (4) through the inlet pipe (11), in which the flocculating agent and the neutralizing agent are introduced into the inlet pipe (11) and mixed in the mixer (12). After being introduced together into the foreign matter agglomeration chamber (2).
이물질응집실(2)에 유입된 오폐수는 각종 이물질이 응집되기 시작하며, 응집된 응집물이 상승되어 응집물부유실(3)로 이동된후, 별도 유입되는 미세기포가 기포분사기(5)에서 분사되며 기포분사기(5)에서 분사되는 기포와 응집물이 접촉결합되어 상부로 부유되는 것이다.The wastewater introduced into the foreign matter agglomeration chamber (2) begins to aggregate various foreign matters, the aggregated aggregate is raised and moved to the flocculation flotation chamber (3), and the microbubbles introduced separately are sprayed from the bubble sprayer (5). Bubbles and aggregates injected from the bubble injector 5 are contacted and floated upward.
이때, 기포와 결합된 응집물은 부유부상하고 분리된 청정수는 내부통체(1a)와 분리격판(1c) 사이로 상승하여 저류 및 산화실(6)로 이동되는 것이다. 용량이 적은 통체에서는 분리격막(1c)를 설치하지 않고 내부통체(1a)를 따라 저류 및 산화실(6)로 이동된다.At this time, the aggregates combined with the bubbles are floating and the separated clean water is raised between the inner cylinder (1a) and the separation plate (1c) is moved to the storage and the oxidation chamber (6). In a cylinder with a small capacity, it moves to the storage and oxidation chamber 6 along the inner cylinder 1a without providing the separating diaphragm 1c.
최상부로 이동된 응집물은 부유물수집실(9)에 누적되면 모타(10a)에 의하여 부유물제거판(10b)을 돌려 부유물수집실(9)에 수거후 별도 배출관(도면에 도시되어 있지 않음)을 따라 외부로 배출된다.When the aggregate moved to the uppermost part is accumulated in the float collecting chamber 9, the float removing plate 10b is collected by the motor 10a and collected in the float collecting chamber 9, followed by a separate discharge pipe (not shown). It is discharged to the outside.
저류 및 산화실(6)로 이동된 1차처리수는 일정시간 지체되면서 하부에 장치된 산화용기체분사기(14)에서 분사되는 산화제(오존 또는 초음파)에 의하여 산화작용이 이루어지며, 이때 발생되는 유해가스는 흡착여과재(6a)에 흡착되고 청정의 가스는 방출된다.The primary treatment water moved to the storage and oxidation chamber 6 is delayed for a certain time and is oxidized by an oxidant (ozone or ultrasonic wave) sprayed from the oxidizing gas injector 14 installed at the lower part. The noxious gas is adsorbed by the adsorption filtration material 6a and the clean gas is discharged.
저류 및 산화실(6) 내의 1차처리수는 자중에 의하여 여과실(7)내에 충전된 여과재(7a)층으로 통과되는 동안 완전한 정화가 이루어진후 배출관(13)을 통하여 외부로 유출되는 것이다.The primary treatment water in the storage and oxidation chamber 6 flows out through the discharge pipe 13 after complete purification while passing through the layer to the layer of filter medium 7a filled in the filter chamber 7 by its own weight.
또한, 상기 응집물부유실(3) 상부에 많은 양의 부유물이 적재되어 있을 경우 큰 용량의 장치일 경우 부유물제거판(10b)를 회동시켜 외부로 유출시키며, 적은 용량의 장치일 경우, 부유물제거판(10b)를 설치하는 대신 유도경사판을 따라 저절로 부유물수집실(9)에 넘어 들어가게 된다.In addition, when a large amount of suspended solids is loaded on the flocculation flotation chamber (3), in the case of a large capacity device, the float removal plate (10b) is rotated and flowed out to the outside. Instead of installing (10b), it will enter the float collection chamber 9 by itself along the inclined slope plate.
상기한 바와 같이, 본 발명은 원수에 함유된 이물질을 응집되게 한후 기포를 침투시켜 부유되게 하므로서 단시간에 응집물을 제거할 수 있는 효과가 있는 것이다.As described above, the present invention is effective to remove the aggregates in a short time by allowing the foreign matter contained in the raw water to aggregate and then penetrate the bubbles to float.
또한, 응집물제거와 함께 저류 및 산화기능과 여과기능을 하나의 장치로 실행될 수 있으므로 단위면적당 정화효율을 상승시킬 수 있는 효과가 있는 것이다.In addition, since the storage and oxidation function and the filtration function together with the removal of aggregates can be performed in one device, the purification efficiency per unit area is increased.
본 발명은 산업용수처리나 농, 축산용 또는 모든 원수를 정화처리할 수 있으며, 대형 또는 소형으로 제조하여 한 개의 장치내에서 여러차례의 정화과정을 실행하는 유익한 발명인 것이다.Industrial Applicability The present invention is an advantageous invention that can purify industrial water treatment, agricultural, livestock, or all raw water, and manufacture a large or small size to carry out several purification processes in one apparatus.
