Description

슬러지 처리장치{A Treatment apparatus of sludge}A treatment apparatus of sludge

본 발명은 일상생활 및 각종 오염원에서 발생하는 음식물쓰레기, 축산분뇨 등의 폐기물을 자원화 처리하는 과정에서 발생되는 폐수 슬러지 처리장치에 관한 것The present invention relates to a wastewater sludge treatment device generated in the process of recycling waste such as food waste and livestock manure generated from daily life and various pollutants.

본 발명은 일상생활 및 각종 오염원에서 발생하는 음식물쓰레기, 축산분뇨 등의 폐기물을 자원화 처리하는 과정에서 발생하는 처리수는 BOD, COD, SS, T-N, T-P등 고농도폐수이므로 고,액분리의 전처리 공정과 정화처리 공정을 거쳐야하는 악성의 폐수다. 상기 폐수는 pH센서를 거쳐 적정량의 중화제와 고분자응집제를 투입하여 탈수처리장치에서 고,액으로 분리하는 슬러지 처리장치에 관한 것으로서 대용량의 슬러지를 효율적으로 처리할 수 있다. 일반적으로 슬러지의 탈수처리방법은 진공탈수법, 원심분리법, 가압탈수법, 분무건조법, 증기건조법, 동경탈수법 등이 있다. 이들 방법들은 대용량의 슬러지를 효율적으로 처리한다는 것은 불가능하다. 슬러지의 탈수시스템은 농축, 소화, 개량, 탈수 및 처분공정으로 이루어져 있다. 농축은 중력식, 부력식, 기계식에 의한 방법으로 농축하는데 농축 정도에 따라 후단 설비인 소화조 및 슬러지 탈수시설 등의 운전관리 여부를 크게 좌우한다. 농축조에서는 슬러지에 함유된 수분을 분리시켜 수분함량을 줄이고 상대적으로 고형물질을 증가시킴으로써 최종적으로 수분을 분리한 만큼 용적을 감소시켜 후단 설비인 소화조로 보내고 소화조에서는 혐기성미생물 또는 호기성미생물에 의해 소화를 시켜 슬러지의 감량화 및 안정화를 동시에 이루어 탈수처리시 슬러지 탈수를 용이하게 해준다. 탈수처리시설로 이송되기 전에 슬러지의 물성을 개선하는 전처리 공정으로 고분자응집제를 투입하여 슬러지 중의 미세입자를 응집시켜 응결물을 형성시켜 탈수기능을 향상시킨다.The present invention is a pretreatment process of solid and liquid separation because the treated water generated in the process of recycling wastes such as food waste and livestock manure generated from daily life and various pollutants is high-concentration wastewater such as BOD, COD, SS, TN, and TP. It is malignant wastewater that has to go through a purification process. The wastewater is directed to a sludge treatment device that separates the wastewater into solid and liquid in a dehydration treatment device by introducing appropriate amounts of a neutralizing agent and a polymer coagulant through a pH sensor, and can efficiently treat large-capacity sludge. In general, sludge dewatering methods include vacuum dehydration, centrifugal separation, pressure dehydration, spray drying, steam drying, and Tokyo dehydration. It is impossible for these methods to efficiently treat large volumes of sludge. The sludge dewatering system consists of thickening, digestion, improvement, dewatering and disposal processes. Concentration is concentrated by gravity, buoyancy, or mechanical methods, and depending on the degree of concentration, the operation management of downstream facilities such as digesters and sludge dewatering facilities is greatly influenced. In the thickening tank, the water contained in the sludge is separated to reduce the water content and relatively increase the solid matter, so that the volume is reduced as much as the water is finally separated and sent to the digester, the downstream facility, where it is digested by anaerobic microorganisms or aerobic microorganisms. It facilitates sludge dewatering during dewatering treatment by simultaneously reducing and stabilizing the sludge. As a pretreatment process to improve the physical properties of the sludge before it is transferred to a dewatering treatment facility, a polymer coagulant is added to agglomerate the fine particles in the sludge to form a condensate to improve the dewatering function

가압탈수, 원심분리, 건조 등에 의한 탈수방법으로 수분을 분리시켜, 분리된 수분은 해양투기를 하고, 케익 형태의 슬러지는 소각, 자원화 등으로 최종처리를 하게 된다. 그러나, 상기의 폐수처리방법은 슬러지 처리공정이 여러 단계로 복잡하고, 공정별로 농축조에서 농축 정도에 따라 후단설비인 소화조 및 탈수시설 등의 운전관리 여부를 좌우하므로 규모가 커지고 규모가 커짐에 따라 농축하는 시간이 길어질 수밖에 없다. 또한, 소화조에서는 혐기성 미생물 또는 호기성 미생물의 활동에 의해 유기성 고형물을 분해하여 안정화시키기 때문에 소화에 따른 시간이 길어질 수밖에 없고 미생물의 활동을 위해 적정온도를 유지해야 하므로 그에 따른 추가적인 비용이 발생하게 된다. 또한 상기 폐수처리방법은 폐수발생 현장과 별도의 장소에 위치해 있어 그에 따른 운반비용이 발생하고, 규모에 비하여 처리효율도 낮을 뿐 아니라 처리시설을 위한 부지의 확보에 어려움이 따른다.Water is separated by dehydration methods such as pressurized dehydration, centrifugation, and drying, and the separated water is dumped into the sea, and cake-shaped sludge is finally treated by incineration and recycling. However, in the wastewater treatment method, the sludge treatment process is complicated in several steps, and the operation and management of the downstream facilities such as the digester and the dehydration facility are affected according to the degree of concentration in the enrichment tank for each process, so the scale increases and the concentration increases as the scale increases. The time to do it is bound to be long In addition, since the digestion tank decomposes and stabilizes organic solids by the activity of anaerobic microorganisms or aerobic microorganisms, the time for digestion is inevitably long and an appropriate temperature must be maintained for the activity of microorganisms, resulting in additional costs. In addition, since the wastewater treatment method is located in a place separate from the wastewater generation site, transportation costs are incurred accordingly, the treatment efficiency is low compared to the size, and it is difficult to secure a site for the treatment facility.

국내 특허등록 제341103호(2002. 06. 04)의 "슬러지 처리장치"는 저면에 바퀴(101)와 전면에 후크(102)를 갖추어 별도의 차량으로 이동 가능한 소형 트레일러식으로 구성하며 상면에는 식물성 폴리머 약품을 약품투입펌프(11)와 공급관(12)을 통하여 투입토록 하는 약품탱크(10)와, 정화조로부터 슬러지를 흡입호우스(22)와 배관(24)을 통해 흡입 수거하는 흡입펌프(21)와 수거되는 슬러지에 약품탱크(10)로부터 투입되는 약품을 교반하는 교반기(30)를 갖춘 박스형의 수거차(100)로 구성하고, 상기 수거차(100)와 연결하고 고정지지대(40)를 이용하여 현장에 고정설치하고, 내부에는 약품이 혼합된 슬러지를 통과시켜 수분은 배수구(46)를 통해 집수조(47)로 배출함과 동시에 순수 슬러지는 수납하도록 하는 다수의 필터판넬(43)(44)과 저면에는 유압의 작동에 의하여 내부에 수납되는 순수 슬러지를 덮개(42)로 개폐되는 후방의 개구부를 통하여 배출토록 하는 덤핑실린더(54)를 갖춘 분리탱크(200)로 구성된 슬러지 처리장치가 공지되어 있으나, 상기 슬러지 처리장치는 오, 폐수에 존재하는 고형분의 응집을 위한 전처리 공정으로 중화처리(pH7~9)를 하지 않고, 에어공급구(35)를 통해서 공급되는 공기에 의해 슬러지와 약품(응집제)혼합물이 와류현상을 일으켜 교반 효율이 떨어져서 탈리수의 수분함수율이 95%에 미치지 못하는 단점이 있다. 또한, 덤핑실린더(54)로 슬러지케익을 분리하는데도 필터판넬(43)(44)의 저항을 받아 분리하는데 어려움이 따른다.The "sludge treatment device" of domestic patent registration No. 341103 (June. 04, 2002) has wheels 101 on the bottom and hooks 102 on the front, so it is composed of a small trailer type that can be moved by a separate vehicle, and has a plant surface on the top. A chemical tank 10 for injecting polymer chemicals through a chemical injection pump 11 and a supply pipe 12, and a suction pump 21 for suctioning and collecting sludge from the septic tank through a suction hose 22 and a pipe 24 ) and a box-type collection vehicle 100 equipped with a stirrer 30 to stir the medicines injected from the chemical tank 10 to the collected sludge, and connect to the collection vehicle 100 and attach a fixed support 40 A plurality of filter panels (43) (44) that are fixed and installed on site using, and allow the sludge mixed with chemicals to pass through the inside to discharge the water to the water collecting tank (47) through the drain port (46) and to accommodate the pure sludge at the same time ) and a sludge treatment device composed of a separation tank 200 equipped with a dumping cylinder 54 to discharge pure sludge accommodated therein through an opening in the rear opened and closed by a cover 42 by the operation of hydraulic pressure on the bottom surface is known. However, the sludge treatment device does not neutralize (pH7~9) as a pretreatment process for agglomeration of solids present in the wastewater, and sludge and chemicals ( The coagulant) mixture causes a vortex phenomenon, which lowers the stirring efficiency, so that the water content of the desorbed water does not reach 95%. In addition, even in separating the sludge cake with the dumping cylinder 54, it is difficult to separate the sludge cake by receiving the resistance of the filter panels 43 and 44.

본 발명은 일상생활 및 각종 오염원에서 발생하는 음식물쓰레기, 축산분뇨 등의 폐기물을 자원화함에 있어서 전처리 공정에서 발생하는 처리수는 BOD, COD, SS, T-N,T-P등 고농도폐수이므로 고액분리의 전처리는 물론 정화처리하기가 매우 어려운 악성폐수다. 이러한 폐수를 처리하는데 있어서, 슬러지 처리장치는 폐수발생 현장에 고정식으로 설치하고 중화제를 투입하여 pH를 알카리성으로 조절한 후, 고분자 응집제를 투입하여 응집시켜 특수필터가 장착된 고액분리기에서 슬러지의 자체 무게에 의해 수분과 슬러지가 필터를 통해 분리된다. 분리된 탈리액은 함수율이 95%이상으로서 별도의 집수탱크에 집수 되고, 슬러지는 다량의 유기물을 함유하고 있어 이를 비료로 재활용한다. 또한 본 발명의 슬러지 처리장치는 폐수발생 현장에 직접 설치하여 처리함으로써 처리용량 및 효율을 증대시키고자 한 것이 특징적인 기술구성이다.In the present invention, in turning wastes such as food waste and livestock manure generated from daily life and various pollutants into resources, the treated water generated in the pretreatment process is high-concentration wastewater such as BOD, COD, SS, TN, TP. It is malignant wastewater that is very difficult to purify. In treating such wastewater, the sludge treatment device is fixedly installed at the wastewater generation site, and after adding a neutralizer to adjust the pH to alkalinity, a polymer coagulant is added to coagulate the sludge by its own weight in a solid-liquid separator equipped with a special filter. Water and sludge are separated through the filter. The separated desorbent has a water content of 95% or more and is collected in a separate collection tank, and the sludge contains a large amount of organic matter, so it is recycled as fertilizer. In addition, the sludge treatment apparatus of the present invention is a characteristic technical configuration to increase the treatment capacity and efficiency by directly installing and treating the wastewater generation site.

이상에서 설명한 바와 같이 일상생활 및 각종 오염원에서 발생하는 폐기물의 자원화 처리공정에서 발생하는 처리수는 BOD, COD, SS, T-N, T-P등 고농도폐수로서 이들은 환경을 오염시키는 주범으로 직매립, 해양투기, 소각 등 최종처리는 환경보호규정이 강화되어 기준에 부합하지 않으면 처분할 수 없게 되었다. 따라서, 본 발명은 처리시설과 오,폐수 발생원이 분리되었던 것을 하나의 시설에서 처리할 수 있도록 함으로서 대용량의 슬러지를 효율적으로 용이하게 처리할 수 있는 장치를 제공한다. 슬러지 처리는 소석회를 사용하여 원수를 pH7 내지 pH12로 중화시키고, 중화된 원수는 응집제탱크(111)에서 물과 고분자응집제를 100;1로 희석한 것을 응집제펌프(112)로 사이클론 교반장치(113)에 투입하여 교반하면 원수 중에 함유된 고체입자들의 응집이 일어난다. 응집이 일어난 원수는 탈수처리시설로 이송된다. 탈수처리 단계는 필터가 장착된 전면판넬(204), 양 벽면판넬(205)(205') 및 분리판넬(202)(202') (202'')을 구비한 탈수기에서 응집된 원수의 자중에 의해 고,액성분이 분리가 된다. 탈리액은 95% 이상의 함수율을 나타내는 대용량의 슬러지 처리하는 효과를 갖는다.As described above, the treated water generated in the process of recycling waste generated from daily life and various pollutants is high-concentration wastewater such as BOD, COD, SS, TN, and TP, which are the main culprits of polluting the environment. The final treatment, such as incineration, cannot be disposed of if it does not meet the standards due to stricter environmental protection regulations. Therefore, the present invention provides an apparatus capable of efficiently and easily processing large-capacity sludge by allowing a treatment facility and a wastewater generation source to be separated in one facility. In the sludge treatment, raw water is neutralized to pH7 to pH12 using slaked lime, and the neutralized raw water is obtained by diluting water and polymer coagulant 100:1 in the coagulant tank 111 with a coagulant pump 112 and a cyclone stirring device 113. Aggregation of the solid particles contained in the raw water occurs when it is added to the water and stirred. The raw water with flocculation is transferred to a dewatering treatment facility. The dehydration treatment step is performed in the self-weight of the aggregated raw water in a dehydrator equipped with a front panel 204 equipped with a filter, both wall panels 205 and 205' and separation panels 202, 202', 202''. The solid and liquid components are separated. The desorbent has the effect of treating large-capacity sludge showing a water content of 95% or more.

본 발명은 해양투기의 기준치인 탈리액의 함수율을 95%이상으로 순도를 높이기 위하여 예의 연구한 결과 SM(Simon Moos)시스템을 보완하여 본 발명을 완성하게 되었다. SMEK(Simon Moos Equipment Korea)시스템의 특징은 대용량의 슬러지처리시 순간응집과 자중(自重)식에 의한 고액분리 및 무동력의 기능을 특징적인 기술구성으로 하고 있다. 본 발명은 크게 응집처리 장치에 의한 응집처리단계와 탈수처리장치에 의한 고,액분리단계로 구분할 수 있다. 응집처리 단계는 원수를 슬러지펌프(101)에 의해 응집기로 유입하여 pH 측정 및 pH 조절부분과 중화제 투입부분, 고분자 응집제 투입부분으로 구분하고, 탈수처리 단계는 함수율이 95%이상인 탈리액과 케익 상태의 고,액분리로 설명할 수 있다.The present invention has completed the present invention by supplementing the SM (Simon Moos) system as a result of intensive research in order to increase the purity of the water content of the tally liquid, which is the standard value for dumping at sea, to 95% or more. The characteristic of the SMEK (Simon Moos Equipment Korea) system is the characteristic technical composition of instantaneous coagulation, solid-liquid separation by self-weight, and non-powered functions when processing large-capacity sludge. The present invention can be largely divided into a coagulation treatment step by a coagulation treatment device and a solid-liquid separation step by a dehydration treatment device. In the coagulation treatment step, raw water is introduced into the coagulator by the sludge pump 101 and divided into a pH measurement and pH control section, a neutralizer input section, and a polymer coagulant input section. It can be explained by solid-liquid separation.

본 발명을 도면을 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the drawings.

응집처리 단계는 오,폐수 등이 모인 원수탱크(106)에 설치된 슬러지펌프(101)의 작동에 의해 원수는 흡입호스(102)를 통하여 응집기로 유입된다. pH센서(104)는 유입구(103)로 유입된 원수의 pH농도를 측정한다. 측정된 pH값은 컨트롤박스(114)에 표시된다. 유입된 원수는 계절별로 pH농도값이 다르므로 중화제의 투입량을 달리한다.In the coagulation treatment step, the raw water is introduced into the coagulator through the suction hose 102 by the operation of the sludge pump 101 installed in the raw water tank 106 in which sewage and wastewater are collected. The pH sensor 104 measures the pH concentration of the raw water introduced into the inlet 103 . The measured pH value is displayed on the control box 114 . The input amount of the neutralizing agent is different because the inflowed raw water has different pH values for each season.

중화제의 투입은 중화제 탱크(105)에서 물과 중화제가 2:1 정도로 희석된 상태로 중화제펌프(107)에 의해 투입 된다. 원수와 중화제는 사이클론 교반장치(108)로 이송되며 여러단계의 반복적인 사이클론 교반으로 혼합되어 응집기의 유입구(110)로 이송되면서 변화된 pH값을 pH센서(109)로 측정한다. 중화제 성분은 일반적으로 소석회를 사용하며, 원수의 중화는 pH7 내지 pH12범위에서 이루어지는 것이 바람직하다. 중화된 원수에 응집제탱크(111)에서 물과 고분자응집제를 100;1로 희석한 것을 응집제펌프(112)로 사이클론 교반장치(113)에 투입하면 중화된 원수와 혼합되는 즉시 응집이 일어나기 시작한다. 응집이 이루어진 원수는 성상에 따라 응집 정도가 차이가 나므로, 샘플링 라인(115)을 통하여 취출(取出), 확인하여 최적의 응집상태가 되도록 응집제의 투입량을 조절한 후, 볼밸브(116)를 작동하여 탈수장치로 이송시킨다. 탈수처리 단계는 도 6에 나타나 있는 것과 같이, 응집된 원수가 탈수기(201)로 이송되고, 이송된 원수는 필터가 장착된 전면판넬(204), 양 벽면판넬(205) 및 분리판넬(202)(202')(202'')을 구비한 탈수기에서 응집된 원수의 자중에 의해 고,액성분으로 분리가 된다. 상기 탈수기 내에서의 원수의 흐름을 원활히 하기 위하여 분리판넬(202)(202'')의 경우 전면부에 공급되는 원수가 정면으로 부딪치므로, 흐름이 원활하도록 삼각형태의 분배구(301)를 설치한다. 상기 탈수기에서 고,액분리가 원활히 이루어져 분리된 탈리액은 95% 이상의 함수율을 나타낸다. 여과된 탈리액은 판넬의 중앙 공간부를 통하여 탈리액 탱크(208)에 집수 되고, 탈리액 탱크 내에 있는 워터펌프(209)에 의해 별도의 집수탱크로 이송이 된다. 또한 탈수기내에 탈수된 슬러지 케익은 덤핑베이스(206)의 덤핑실린더(207)에 의해 58°까지 들어올려 슬러지를 호퍼로 옮겨주게 되는데, 이때 분리판넬(202)(202') (202'')의 입구쪽과 출구쪽의 판넬의 폭이 동일할 경우 슬러지케익이 호퍼쪽으로 원활하게 이동하지 못한다. 따라서, 입구쪽에서 출구쪽으로의 판넬 폭을 테이퍼지게 하여 슬러지 케익의 이동을 원활히 할 수 있어 슬러지 케익의 분리가 양호하다. 또한, 분리판넬(202)(202'')의 후단부에 청소부를 두어 고,액분리장치 내에 남아 있는 슬러지를 고압 살수기로 청소한 후 청소 수는 다시 원수탱크로 보내져 항상 청결을 유지하고 장치의 부식을 방지할 수 있는 특징이 있다.The neutralizing agent is injected by the neutralizing agent pump 107 in a state in which water and the neutralizing agent are diluted about 2:1 in the neutralizing agent tank 105 . The raw water and the neutralizing agent are transferred to the cyclone agitator 108, mixed by repeated cyclone agitation of several steps, and the changed pH value is measured with the pH sensor 109 while being transferred to the inlet 110 of the coagulator. The neutralizer component generally uses slaked lime, and the neutralization of raw water is preferably made in the pH7 to pH12 range. When neutralized raw water is diluted with water and polymer coagulant in the coagulant tank 111 by 100; 1 with the coagulant pump 112 to the cyclone stirring device 113, agglomeration starts immediately after mixing with the neutralized raw water. Since raw water with coagulation has a different degree of coagulation depending on its properties, it is taken out through the sampling line 115 and checked to adjust the input amount of the coagulant so that it is in an optimal coagulation state, and then the ball valve 116 is operated. and transferred to the dehydrator. In the dehydration treatment step, as shown in FIG. 6 , the aggregated raw water is transferred to the dehydrator 201 , and the transferred raw water is a filter-equipped front panel 204 , both wall panels 205 and a separation panel 202 . (202') and (202'') are separated into solid and liquid components by the weight of the aggregated raw water in the dehydrator. In order to facilitate the flow of raw water in the dehydrator, in the case of the separation panels 202 and 202 '', the raw water supplied to the front part collides in front, so a triangular-shaped distribution port 301 is installed to facilitate the flow. install In the dehydrator, solid and liquid separation is smoothly performed, and the separated desorbent exhibits a water content of 95% or more. The filtered talismant is collected in the eliminator tank 208 through the central space of the panel, and is transferred to a separate collection tank by the water pump 209 in the eliminator tank. In addition, the sludge cake dehydrated in the dehydrator is lifted up to 58° by the dumping cylinder 207 of the dumping base 206 and transferred to the hopper, at this time the separation panels 202, 202', 202'' If the width of the inlet and outlet panels is the same, the sludge cake cannot move smoothly toward the hopper. Therefore, the sludge cake can be smoothly separated by tapering the width of the panel from the inlet to the outlet, so that the sludge cake can be separated. In addition, a cleaning unit is placed at the rear end of the separation panel 202, 202'', and the sludge remaining in the liquid separation device is cleaned with a high-pressure water dispenser, and then the cleaning water is sent back to the raw water tank to always maintain cleanliness, It has features to prevent corrosion.
