For example, the sludge cake generated in the water and sewage treatment process is dried and then calcined at a high temperature of 1000 to 1400 ° C., and treated in a harmless form. Apparatus for use in a treatment apparatus relates to a water and sewage sludge forming apparatus for molding primary dried sludge cake into a size of 5 to 50 mm in diameter.

일반적으로 상,하수 처리장에서 물을 정수하는 처리과정에서 약품인 응집제를 투입하여 슬러지를 침전시키며, 침전된 생슬러지는 수분 함유량이 94∼98％의 수분을 함유하고 있으며, 생슬러지에 함유된 수분을 제거하기 위하여 도 6의 (가)에 도시되어 있는 바와같이 진공여과기의 회전드럼(1) 표면에 여포(2)가 부착되어 있고 진공펌프로 회전드럼(1) 내부를 진공상태로 만들면 슬러지가 여포(2)의 표면에 흡착되어 물만 여포(1)를 통과해서 생슬러지에 함유된 물만 탈수하여 슬러지케이크(3)만 걸러내는 진공탈수기와, 도 6의 (나)에 도시되어 있는 바와 같이 판상의 다공질 지지체(4)에 여포(5)를 펴고 고압에 의해 가압 탈수하여 슬러지케이크(3)만 걸러내는 가압탈수기 등에 의해 생슬러지에 함유된 수분을 제거한다.Generally, in the process of water purification in water and sewage treatment plants, a flocculant, which is a chemical, is added to precipitate sludge, and the precipitated raw sludge contains 94 to 98% of water, and the moisture contained in the fresh sludge. As shown in (a) of FIG. 6, the follicle 2 is attached to the surface of the rotary drum 1 of the vacuum filter and the sludge is vacuumed inside the rotary drum 1 with a vacuum pump. A vacuum dehydrator adsorbed on the surface of the follicle 2 to pass only the water through the follicle 1 to dehydrate only the water contained in the fresh sludge to filter only the sludge cake 3, and a plate-like shape as shown in FIG. Spread the follicles 5 on the porous support 4 of and pressurized dewatering by high pressure to remove moisture contained in the raw sludge by a pressurized dehydrator for filtering only the sludge cake 3.

이와 같이 종래에는 상기의 대기압과 진공과의 압력차를 이용하여 탈수시키는 진공탈수기와 기계적인 가압에 의해 탈수하는 가압탈수기 등에 의해 슬러지에 함유된 수분을 탈수한 탈수슬러지(이하 "슬러지케이크"라 함)를 처리하기 위하여 차량의 운반에 의해 땅속에 매립하여 처분하거나, 슬러지수송선의 운반에 의하여 먼 해양에 투기하여 처분하는 알려져 있다.As described above, in the related art, a dehydration sludge which dehydrates the water contained in the sludge by a vacuum dehydrator for dehydrating using the pressure difference between the atmospheric pressure and the vacuum and a pressurized dehydrator for dehydration by mechanical pressure is hereinafter referred to as "sludge cake" Is known to be disposed in the ground by transportation of vehicles to be disposed of, or to be disposed of by dumping in the distant ocean by transportation of sludge carriers.

그러나, 수분함유량이 70∼80％ 정도 되는 상기의 슬러지케이크를 처리하기 위하여 땅속에 매립하는 경우에는 토지의 재활용과 지하수오염 등의 환경 오염 문제가 발생하며, 해양에 투기할 경우에는 해수 탁도의 변화로 플랑크톤의 생성 촉진 및 어류의 생육을 저하하는 등 생태계가 파괴되는 등의 많은 문제점이 있었다.However, when landfilled in order to treat the sludge cake with a water content of about 70 to 80%, environmental pollution such as land recycling and groundwater pollution occurs.

After the distributor 90 is sent, the plastic sludge cake having a diameter of 5 to 50 mm in the distributor 90 is collected and collected in large, medium, and small sizes, and collected in large, medium, and small sizes. Sludge cake is recycled as compost of soil activated soil and various crops and aquaculture.

본발명의 상,하수용 슬러지 성형장치을 이용하여 슬러지케이크를 직경 5∼50㎜의 크기로 절단 성형하는 작용관계를 구체적으로 설명하면 다음과 같다.Referring to the working relationship of the sludge cake is cut to a size of 5 ~ 50mm in diameter using the sludge forming apparatus for water and sewage of the present invention in detail as follows.

몸체(28)내로 공급된 덩어리로 된 슬러지케이크는 상,하수용 슬러지 성형장치(30)의 투입구를 통하여 몸체(28)내로 투입된 슬러지케이크는 모터(31)의 회전이 체인(31')에 의해 스프로킷(31")에 전달되면 스프로킷(31")의 회전에 의해 스프로킷(31")과 일체로 형성된 회전축(32), 교반날개(33) 및 이송스크류(34)가 회전하면 몸체(28)내로 투입된 슬러지케이크가 교반날개(33)에 의해 교반되면서 이송스크류(34)의 회전에 의해 아래로 압송된다.Sludge cake made of agglomerates supplied into the body 28 is the sludge cake introduced into the body 28 through the inlet of the water and sewage sludge forming apparatus 30, the rotation of the motor 31 by the chain 31 ' When transmitted to the sprocket 31 ", the rotary shaft 32, the stirring blade 33 and the transfer screw 34 formed integrally with the sprocket 31" by the rotation of the sprocket 31 "rotates into the body 28. The injected sludge cake is fed downward by the rotation of the transfer screw 34 while being stirred by the stirring blade 33.

이송스크류(34)에 의해 아래로 압송된 슬러지케이크는 이송부(35)하단에 설치된 배출판(36)의 통공(36')을 통하여 아래로 배출되면 주기적으로 작동하는 에어실린더(38)의 작동에 의해 안내부(37)에 안내되는 박판의 댐퍼(39)가 좌우로 이동하여 슬러지케이크를 절단 성형한다.The sludge cake pressurized downward by the conveying screw 34 is discharged downward through the through hole 36 'of the discharge plate 36 installed at the lower part of the conveying part 35 to operate the air cylinder 38 which operates periodically. The damper 39 of the thin plate guided to the guide portion 37 is moved left and right to cut and shape the sludge cake.

이때, 슬러지케이크의 크기는 배출판(36)에 형성된 통공(36')의 직경 및 에어실린더(38)의 작동 주기에 따라 정해지며, 배출판(36)에 형성된 통공(36')의 직경은 5∼50㎜로 형성된다.At this time, the size of the sludge cake is determined according to the diameter of the through-hole 36 'formed in the discharge plate 36 and the operating cycle of the air cylinder 38, the diameter of the through-hole 36' formed in the discharge plate 36 It is formed in 5-50 mm.

상기와 같이 직경 5∼50㎜의 크기로 절단되어 성형된 슬러지케이크가 안내부(37)에 안내되어 아래로 낙하하게 되는 것이다.As described above, the sludge cake formed by cutting to a size of 5 to 50 mm in diameter is guided to the guide part 37 to fall down.

상기와 같이 본 발명에 의해 슬러지에 함유된 수분을 탈수한 슬러지케이크를 건조한 후, 1000∼1400。C의 고온에서 소성 처리시, 콩알 크기의 형태로 만들어 토양 활성화 배양토 및 각종 농작물과 수중재배의 퇴비로 재활용하므로서, 탈수기 등에 의해 슬러지에 함유된 수분을 탈수한 슬러지케이크를 땅속에 매립하여 처분하거나 먼 해양에 투기하지 않아 슬러지케이크를 처리하기 위한 제반 비용을 경감하는 동시에 토지의 활용과 지하수오염 등의 환경 오염를 방지하며, 해양의 생태계를 그대로 유지할 수 있는 효과가 있는 것이다.As described above, after drying the dewatered sludge cake in the sludge according to the present invention, when calcined at a high temperature of 1000 ~ 1400 ° C, compost of soil activated culture soil and various crops and underwater cultivation in the form of soybean size By reclaiming waste, sludge cake that has dehydrated the water contained in sludge by a dehydrator, etc. is buried in the ground or disposed of in the distant ocean to reduce the cost of treating sludge cake, while reducing land use and groundwater pollution. It is effective in preventing environmental pollution and maintaining the marine ecosystem.
