본 고안은 생활하수 분뇨 또는 각종식품 가공공장 및 화학공장등에서 발생한 폐수의 2차처리설비에서 배출되는 활성스러지와 같은 미세한 난탈수성(難脫水性)스러지를 저함수율로 탈수시키는 여과탈수장치에 관한 것으로, 먼저 본 고안 난탈수성스러지의 탈수를 용이하게 하기 위하여, 탈수하려는 스러지에 적합한 고분제응집제로 응집시킨 상태로 본 고안의 투입구에 공급시키면 0.1∼0.3mm 정도의 간격을 갖인 스롯드형으로된 원주형스크린 위로 균일하게 이동되어 응집된 고형분과 여액이 분리여과되어 1∼3%의 농도 스러지가 6∼10% 정도의 농도로 농축된다.The present invention is a filter dewatering device for dehydrating fine dehydrated sludge, such as activated sludge discharged from secondary treatment facilities of wastewater generated from domestic sewage manure or various food processing plants and chemical plants, at low water content. In order to facilitate the dehydration of the inventive dehydrated sludge, the present invention is supplied to the inlet of the present invention in a flocculated state with a coagulant coagulant suitable for dewatering sludge, and has a spacing of about 0.1 to 0.3 mm. The aggregated solids and filtrate are separated and filtered uniformly over the cylindrical screen, and the concentration sludge of 1 to 3% is concentrated to the concentration of 6 to 10%.
이와같이 농축된 스러지를 흡수성이 강한 스펀지형밴드로 둘러싸여진 다공으로된 회전드럼에 의하여 탈수이동되고 고무밸트에 의하여 압착탈수시키므로서 난탈수성스러지를 효과적으로 여과탈수케한 것이다.In this way, the concentrated sludge is dehydrated by a porous rotating drum surrounded by a highly absorbent sponge-type band, and compressed and dehydrated by a rubber belt to effectively filter and dehydrate dehydrated sludge.
종래의 여과탈수장치는 스러지중의 수분과 고형물을 분리하기 위하여 진공펌프, 고압펌프 또는 고속회전체의 원심력에 의하여 여과탈수 처리하였기 때문에 압력차 또는 중력의 가속도를 이용하고 있어 처리과정에서 고형물의 형상이 파괴되기도 하고 이상현상의 압축등으로 고형물의 분리가 잘 이루어지지 않기 때문에 많은량의 여과보조제를 투입하여 여과효율의 저하를 방지하는 방식을 사용해왔기 때문에 처리비용이 많이들고 장치가 복잡하여 고장율이 많아 능률적으로 처리할 수 없는 문제점이 있었다.The conventional filter dewatering device uses a pressure difference or an acceleration of gravity due to the centrifugal force of a vacuum pump, a high pressure pump or a high-speed rotating body in order to separate water and solids in sludge. Since the solids are not easily separated due to the breakage or abnormal compression, a large amount of filter aid is added to prevent the degradation of the filtration efficiency. There were many problems that could not be efficiently processed.
본 고안은 이와같은 문제점을 해소하기 위하여 미세한 간격을 가진 스롯드형으로된 원주형스크린과 흡수성이 강한 스펀지형밴드로 둘러싸여진 다공으로된 회전드럼에 의하여 여과탈수시킨 후에 고무밸트에 의하여 압착탈수시켜 스러지케익을 얻어낼 수 있게 하므로서 난탈수스러지를 효과적으로 여과탈수처리할 수 있게 한 것이다.In order to solve this problem, the present invention is dewatered by a rubber belt after dehydration by filtration and dehydration by a porous drum with finely spaced rod-shaped screen with a spacing and absorbent sponge band. By allowing the sludge cake to be obtained, the dewatering sludge can be effectively filtered and dewatered.
이와같이된 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.When the present invention is described in detail by the accompanying drawings as follows.

The drum (8) is installed to surround the sludge isolation follicle (9) at the top thereof. The follicle 9 is separated from the absorbent sponge-like band 7 by the guide rollers 10, 10a, 10l, and surrounded by the sponge-like band 7 and the follicle 9. Sponge-type band 7 and follicles are wound by installing the rubber belt 12 on the upper fixing roller 11 and the lower flow roller 11a installed on the rear upper part of the rotary filtration drum 8 having the perforated holes 8a. (9) is pressed and dewatered.
그리고 고무밸트(12)에 전착된 스러지를 스크레퍼(5a)에 의하여 제거시키며 스러지케익의 수분 함량에 따라 압력 조절레버(13)에 의하여 하부유동로울러(11a)의 압력을 조절한다.And remove the sludge electrodeposited to the rubber belt 12 by the scraper (5a) and adjust the pressure of the lower flow roller (11a) by the pressure control lever 13 in accordance with the water content of the sludge cake.
그리고 스펀지형 밴드(7)로 둘러싸여진 다공(8a)으로 된 회전여과드럼(8) 전방에 압착탈수로울러(14)를 설치하여 스펀지형 밴드(7)를 탈수하는데 이때 레버(13a)에 의하여 압력을 조절할 수 있게 하며 스펀지형 밴드(7)와 스러지격리 여포(9)를 분산관(15)(15a)으로 세척할 수 있게 하고 회전여과드럼(8)의 하부에는 이차여액유도배출통(16)을 설치하여서된 것이다.In addition, a compression dewatering roller 14 is installed in front of the rotary filtration drum 8 formed of the porous 8a surrounded by the sponge-type band 7 to dewater the sponge-type band 7, wherein the pressure is applied by the lever 13a. And the sponge-like band (7) and the sludge isolation follicles (9) can be washed with the dispersion pipes (15) and (15a), and the lower portion of the rotary filter drum (8) has a secondary filtrate induction container (16). )
이상과 같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.
난탈수성스러지의 탈수를 용이하게 하기 위하여 탈수하려는 스러지에 적합한 고분제응집제로 응집시킨 상태의 것을 재치틀(1)의 정방상부에 설치된 0.1∼0.3mm 정도의 간극을 갖인 스롯드형으로된 원주형 스크린(2)의 전방에 설치된 스러지공급통(3)에 공급시키게되면 회전하고 있는 원주형 스크린(2)에 의하여 균일하게 이송될 때 원주형 스크린(2)에 형성된 0.1∼0.3mm 정도의 간극으로 여과탈수되어 1%∼3% 정도의 농도로된 스러지가 6%∼10% 정도의 농도로 고형분과 여액이 분리농축된다. 여기에서 여과탈수된 여액은 원주형 스크린(2)의해 내부에서 밖으로 통과배출되어 스크린(2)을 세척하게 된다.In order to facilitate the dehydration of the hardly dehydrated sludge, the flocculated flocculant with a polymer coagulant suitable for the sludge to be dewatered has a cylindrical shape of a rod having a clearance of about 0.1 to 0.3 mm provided on the square upper part of the mounting frame (1). When supplied to the sludge feed container (3) installed in front of the screen (2) is a gap of about 0.1 to 0.3mm formed in the cylindrical screen (2) when uniformly conveyed by the rotating cylindrical screen (2) The solids and the filtrate are separated and concentrated to a concentration of about 6% to 10% by sludge which is dewatered by filtration to a concentration of about 1% to 3%. The filtrate dewatered here is passed out from the inside by the columnar screen (2) to clean the screen (2).
1차여액유도배출통(4)에 의하여 유도배출되고 위에서와 같이 6%∼10% 정도로 농축된 스러지는 회전하고 있는 원주형 스크린(2)의 후방에 설치된 스크래퍼(5)에 의하여 원주형 스크린(2)의 표면에서 분리시켜 경사지게 설치된 안내판(6)에 낙하시키게 된다.Cylindrical screen (2) by scraper (5) installed behind the rotating columnar screen (2) guided discharged by the primary filtrate guide discharge vessel (4) and concentrated to about 6% to 10% as above. It is separated from the surface of the) to fall on the guide plate 6 installed inclined.
이와같이 경사지게 설치된 안내판(6)에 낙하된 스러지는 회전여과드럼(8)의 외주에 둘러싸여진 흡수력이 강한 스펀지형 밴드(7)의 접지되게 설치된 여포(9)상에 균일하게 이송되도록 하여 스러지 함유하고 있는 잔여여액이 이 여포(9)와 접하고 있는 흡수력이 강한 두터운 스펀지형 밴드(7)의 모세관현상에 의하여 여액을 흡수하게 된다.The sludge dropped on the guide plate 6 inclined in this manner is uniformly transported on the grounded follicle 9 of the absorbent strong sponge type band 7 surrounded by the outer periphery of the rotary filtration drum 8, and contains sludge. The remaining filtrate absorbs the filtrate by the capillary phenomenon of the thick sponge type band 7 having strong absorption force in contact with the follicle 9.
이와같이 모세관현상과 중력에 의하여 빠른 속도로 여액을 흡수한 두터운 스펀지형 밴드(7)와 여포(9)를 회전여과드럼(8)의 후방상부에 설치한 상부고정로울러(11)와 하부유동로울러(11a)에 감아 설치한 고무밸트(12)에 의하여 서서히 가압탈수되도록 한다.Thus, the upper fixed roller 11 and the lower flow roller having thick sponge-like bands 7 and follicles 9, which absorb the filtrate at high speed by capillarity and gravity, are installed on the rear upper part of the rotary filter drum 8 11a) is gradually depressurized by the rubber belt (12) wound around the installation.
이때의 가압조절은 압력조절레버(13)에 의하여 조절하게 된다.At this time, the pressure control is controlled by the pressure control lever (13).
이와같이 가압탈수 종료된 스러지케익은 하부의 유동로울러(11a) 후방으로 배출되어 여포(9)에서 고무밸트(12)에 전량 격착 이송되는 것을 스크래퍼(5a)에 의하여 제거시킨다.In this way, the dewatered sludge cake is discharged to the rear of the lower flow roller (11a) to remove all the squeezed and transported from the follicle (9) to the rubber belt (12) by the scraper (5a).
이때의 스러지케익은 함수율이 60%∼70% 정도이다.The sludge cake at this time has a moisture content of about 60% to 70%.
여기에서 회전여과드럼(8)의 외주에 설치되는 여포(9)의 세척은 분사관(15)에 의하여 청수를 분사시켜 실시하고 흡수력이 강하 두터운 스펀지형 밴드(7)는 분사관(15a)을 이용하여 청수로 세척한 후에 회전여과드럼(8) 전방에 설치한 압착탈수로울러(14)에 의하여 압착시켜 스펀지형 밴드(7)가 함유하고 있는 수분을 탈수한다.Here, the cleaning of the follicles 9 installed on the outer circumference of the rotary filtration drum 8 is performed by injecting fresh water by the injection pipe 15, and the thick sponge-type band 7 having a strong absorption force makes the injection pipe 15a open. After washing with fresh water, it is compressed by a dehydration roller 14 installed in front of the rotary filtration drum 8 to dehydrate the water contained in the sponge-like band 7.
스펀지형 밴드(7)를 탈수하는 또다른 예로서 진공흡수장치나 공기를 분사시켜 탈수시킬수도 있다.As another example of dewatering the sponge-like band 7, it may be dewatered by injecting a vacuum absorber or air.
여기에서 배출되는 여액은 이차여액유도배출통(16)으로 유도되어 배출처리된다. 위에서 설명한 바와같은 수단을 반복하므로서 계속해서 난탈수성스러지를 능율적으로 저함수율 즉 60%∼70%의 스러지케익으로 처리할 수 있을뿐 아니라, 구조가 간단하여 설치가 용이하고 고장율이 적어 그 수명이 긴 이점이 있는 것이다.The filtrate discharged here is guided to the secondary filtrate induction discharge container 16 is discharged. By repeating the means described above, it is possible to continuously treat the non-dehydrated sludge with a sludge cake having a low water content, that is, 60% to 70%, as well as its simple structure and easy installation and low failure rate. This is a long advantage.
