Abstract
본 발명은 탈질실(B) 및 질산화실(C)이 상하로 형성된 좌측통체(20)의 일측에 침전실(E)이 포함된 우측통체(20)가 부착 형성되므로, 내,외통으로 구성되어 탈질실, 질산화실 및 침전실이 단일조에 형성된 하수정화처리장치에 비해 그 제조작업이 간편함과 아울러 좌,우측통체의 직경이 축소되고, 탈질실(B)과 질산화실(C)이 독립되도록 구획됨과 아울러 탈질실(B)을 통과한 하수는 월류벽(63)을 넘쳐흘러 순환실(D)을 거쳐 질산화실(C)로 유입되므로 탈질실(B)에 있는 탈질 미생물은 질산화실로의 이동이 억제되므로 탈질 미생물이 탈질실(B)에 고농도로 전속되며, 질산화실(C)을 통과한 하수는 상승관(22), 유도관체(34), 침전실(E)을 거쳐 슬러지가 침강분리된 하수가 월류벽(63)을 넘쳐흘러 분기관(65), 관로(67)를 통해 탈질실(B)로 순환되므로 질산화 미생물은 탈질실(B)로의 이동이 억제되면서 질산화실(C)에 고농도로 전속되기 때문에 하수의 정화처리 효율이 향상되며, 송풍기(51)(53)에 의한 공기의 송출만으로 하수가 순환되고 배출구(23)로 배출되는 하수에 의하여 교반수단(40)이 회전되므로 하수정화처리장치의 시설비용 및 유지비용도 절감되는 하수의 질소, 인 제거장치에 관한 것이다.In the present invention, since the denitrification chamber (B) and the nitrification chamber (C) are formed on the one side of the left cylinder 20 formed up and down, the right cylinder 20 including the settling chamber E is attached to the inner cylinder and the outer cylinder. Compared to the sewage treatment apparatus in which the denitrification chamber, the nitrification chamber and the precipitation chamber are formed in a single tank, the manufacturing work is simpler, and the diameter of the left and right cylinders is reduced, and the denitrification chamber (B) and the nitrification chamber (C) are separated. In addition, the sewage that has passed through the denitrification chamber (B) flows over the overflow wall (63) and flows into the nitrification chamber (C) through the circulation chamber (D), so that the denitrification microorganisms in the denitrification chamber (B) do not move to the nitrification chamber. Since it is suppressed, the denitrification microorganism is transmitted to the denitrification chamber (B) at a high concentration, and the sewage that has passed through the nitrification chamber (C) is sedimented and separated from the sludge through the riser (22), the guide tube (34), and the settling chamber (E). Since the sewage overflows the overflow wall 63 and circulates through the branch pipe 65 and the pipe 67 to the denitrification chamber B, the nitrifying microorganism is denitrification chamber. Since the movement to (B) is suppressed, the sewage treatment efficiency is improved because it is transmitted to the nitrification chamber C at a high concentration, and the sewage is circulated by only the air discharged by the blowers 51 and 53 to the outlet 23. Since the stirring means 40 is rotated by the discharged sewage, it relates to the nitrogen and phosphorus removal device of the sewage, which also reduces the facility cost and maintenance cost of the sewage purification treatment apparatus.
Description
본 발명은 하수의 질소 및 인을 제거하는 장치에 관한 것으로서, 특히 미생물을 이용하여 오,폐수에 함유된 부영양화 원인 물질인 질소 및 인을 생물학적으로 제거하는 장치에 관한 것이다.The present invention relates to a device for removing nitrogen and phosphorus from sewage, and more particularly, to a device for biologically removing nitrogen and phosphorus, which are eutrophication agents contained in wastewater using microorganisms.
생물학적으로 하수에 함유된 질소를 제거하는 방법은 주로 암모니아성 질소형태로 하수중에 함유된 질소가 질산화 미생물인 니트로소모너스(Nitrosomonas)나 니트로벡터(Nitrobacter)에 의하여 용존산소(DO)가 있는 호기성 조건에서 산화태 질소인 아질산성 질소(NO2- N) 또는 질산성 질소(NO3- N)로 산화된 다음, 용존산소가 없는 무산소조건에서 상기의 산화태 질소가 탈질 미생물에 의해 환원되어 질소가스 형태로 대기중으로 방출됨으로써 하수에 함유된 질소가 제거된다.Biological removal of nitrogen in sewage is mainly in the form of ammonia nitrogen, and aerobic conditions with dissolved oxygen (DO) by Nitrosomonas or Nitrobacter, which nitrogen is contained in sewage, are nitrifying microorganisms. Is oxidized to nitrite nitrogen (NO 2 -N) or nitrate nitrogen (NO 3 -N), which is the oxidizing nitrogen at, and then the nitrogen oxide is reduced by the denitrification microorganism under anoxic conditions without dissolved oxygen. In the form, it is released into the atmosphere to remove nitrogen from the sewage.
즉 질산화 미생물은 무기탄소를 영양원으로 섭취하여 암모니아성 질소를 산화태 질소로 산화시키고, 탈질 미생물은 유기성 탄소를 영양원으로 섭취하면서 무산소조건에서 산화태 질소를 전자수용체로 이용하기 때문에 산화태 질소는 질소가스로 환원되어 질소가 제거된다.Nitric oxide microorganisms consume inorganic carbon as a nutrient source to oxidize ammonia nitrogen to oxidized nitrogen, while denitrified microorganisms consume organic carbon as nutrients and use nitrous oxide as an electron acceptor under anoxic conditions. Reduced to gas to remove nitrogen.
한편, 에시내토벡터(Acinetobacter)로 대표되는 인제거 미생물은 혐기조건에서 초산등의 유기산을 체내에 흡수하면서 균체내의 인을 방출하고 호기조건에서는 혐기조건에서 흡수한 유기산 등을 영양원으로 하면서 균체내에 정상적으로 갖고 있는 균체 건조 중량의 1-2%에 해당하는 인보다 많은 4-7%에 해당하는 인을 섭취하기 때문에 인제거 미생물이 호기조건에서 인을 과잉 섭취했을 때 인제거 미생물이 함유된 슬러지를 외부로 배출함으로써 하수에 포함된 인이 제거된다.On the other hand, phosphorus-removing microorganisms represented by Acinetobacters release phosphorus in cells while absorbing organic acids such as acetic acid in the body under anaerobic conditions, and nutrients such as organic acids absorbed under anaerobic conditions under aerobic conditions as nutrients. Since the intake of 4-7% of phosphorus is higher than that of 1-2% of the dry weight of normal cells, the sludge containing dephosphorization microorganisms is removed when the dephosphorization microorganisms ingest the phosphorus in aerobic conditions. By discharging to the outside, phosphorus contained in sewage is removed.
상기의 생물학적으로 하수에 함유된 질소 및 인을 제거하는 종래기술에 의한 하수의 영양소 제거설비는 도3에 도시된 바와 같이, 침사조(1), 혐기조(2), 무산소조(3), 호기조(4), 침전조(5)로 구성되어, 침사조(1)에서 토사류가 침강되어 분리된 유입하수가 혐기조(2), 무산소조(3), 호기조(4) 및 침전조(5)를 순차적으로 통과하면서 하수에 함유된 질소, 인 및 슬러지가 제거되어 침전조(5)로부터 방류되고, 호기조(4)를 통과한 하수의 일부는 펌프(P1)에 의하여 관로(6)을 통해 무산소조(3)로 순환되고, 침전조(5)에서 침전된 슬러지는 펌프(P2)에 의하여 관로(7)를 통해 혐기조(2)로 반송되며, 슬러지의 일부는 관로(8)을 통해 외부로 배출된다.The nutrient removal equipment of the sewage according to the prior art for removing the biologically contained nitrogen and phosphorus in the sewage is, as shown in Figure 3, the sedimentation tank (1), anaerobic tank (2), anoxic tank (3), aerobic tank ( 4), consisting of a sedimentation tank (5), sedimentation sediment settled in the sedimentation tank (1) while the influent sewage separated through the anaerobic tank (2), anoxic tank (3), aerobic tank (4) and sedimentation tank (5) in sequence Nitrogen, phosphorus and sludge contained in the sewage are removed and discharged from the settling tank 5, and a part of the sewage passing through the aerobic tank 4 is circulated to the anoxic tank 3 through the pipeline 6 by a pump P 1 . And, the sludge precipitated in the settling tank (5) is returned to the anaerobic tank (2) through the pipe line 7 by the pump (P 2 ), a part of the sludge is discharged to the outside through the pipe line (8).
즉, 침사조(1)로부터 공급된 토사류등이 제거된 하수는 DO, NO2, SO2등의 전자수용체가 존재하지 않는 혐기조(2)에서 교반설비에 의하여 침전조(5)로부터 관로(7)을 통해 반송된 슬러지와 교반되면서 인제거 미생물의 균체내에 포함된 인이 체외로 배출되고, 무산소조(3)를 통과한 하수는 호기조(4)에서 하수에 함유된 암모니아성 질소가 질산화 미생물에 의해 산화태 질소인 아질산성 질소 또는 질산성 질소로 산화되어 그 일부가 관로(6)를 통해 무산소조(3)로 순환되는 데 무산소조(3)에서는 혐기조(2)로부터 공급된 하수와 상기 호기조(4)로부터 순환된 하수가 교반되면서 하수에 포함된 산화태 질소가 탈질 미생물에 의해 환원되어 질소가스 형태로 대기중으로 방출된다.That is, sewage from which sediments and the like supplied from the sedimentation tank 1 has been removed is an anaerobic tank 2 in which no electron acceptors such as DO, NO 2 , and SO 2 are present. Phosphorus contained in the cells of the phosphorus removal microorganism is discharged to the body while being stirred with the sludge returned through the sludge, and the ammonia nitrogen contained in the sewage in the aerobic tank (4) is oxidized by the nitrifying microorganisms in the sewage through the anoxic tank (3). Oxygen is oxidized to nitrite nitrogen or nitrate nitrogen, which is natural nitrogen, and a part of it is circulated to the anaerobic tank 3 through the pipe line 6, in the anaerobic tank 3, from the sewage supplied from the anaerobic tank 2 and the aerobic tank 4; As the circulated sewage is stirred, the nitrogen oxides contained in the sewage are reduced by the denitrifying microorganisms and released into the atmosphere in the form of nitrogen gas.
한편, 호기조(4)에서는 상기한 바와 같이 무산소조로부터 유입된 하수가 폭기 되면서 암모니아성 질소가 산화태 질소로 산화됨과 아울러 인제거 미생물은 인을 과잉 섭취하여 무산소조로 순환되거나 침전조로 유입되고, 침전조(5)에서는 슬러지가 침전되어 상징수는 방류되고 슬러지는 펌프(P2)에 의하여 관로(7)을 통해 혐기조(2)로 반송되며 잉여슬러지는 간헐적으로 관로(8)을 통하여 외부로 배출된다.On the other hand, in the aerobic tank (4) as described above, as the sewage introduced from the anoxic tank is aerated, the ammonia nitrogen is oxidized to nitrogen oxide, and the phosphorus removing microorganism is excessively ingested with phosphorus to circulate to the anoxic tank or flow into the settling tank, In 5) sludge is settled, the supernatant is discharged, and the sludge is returned to the anaerobic tank 2 through the pipeline 7 by the pump P 2 , and the excess sludge is intermittently discharged to the outside through the pipeline 8.
그러나, 상기한 하수의 영양소 제거설비는 혐기조(2), 무산소조(3), 호기조(4) 및 침전조(8)가 각각 별개로 제조되어 서로 분리된 상태로 설치되기 때문에 많은 설치 면적이 소요될 뿐만 아니라 하수를 순환시키거나 슬러지를 반송시키기 위하여 펌프(P1)(P2)를 필요로 함과 아울러 혐기조(2), 무산소조(3)내에 설치된 교반설비의 작동시 동력이 소요되므로 설치비용 및 운전비용과 유지관리비가 증대되는 문제점이 있었다.However, the nutrient removal equipment of the sewage is not only requires a lot of installation area because the anaerobic tank (2), anaerobic tank (3), aerobic tank (4) and sedimentation tank (8) are separately manufactured and installed in a separate state from each other. In order to circulate the sewage and to return the sludge, pumps (P 1 ) and (P 2 ) are required, and power is required to operate the agitating facilities installed in the anaerobic tank (2) and anoxic tank (3). And maintenance costs were increased.
본 발명자는 상기한 종래기술의 문제점을 해결하기 위하여 1995. 6. 5 특허출원번호 제95-14820호로 출원된 "유기성 오·폐수 정화장치"를 발명한 바 있다.The present inventor has invented the "organic waste water purification apparatus" filed in Patent Application No. 95-14820 No. 95-14820 to solve the above problems of the prior art.
상기 선출원 발명은 종래의 혐기조, 무산소조, 호기조 및 침전조의 기능을 단일의 정화조에 의하여 달성할 수 있는 발명을 개시하고 있다. 그러나 상기 선출원 발명은 내,외통으로 구성되어 무산소조의 기능을 달성하는 탈질부(DN)와 호기조의 기능을 달성하는 질산화부(OX)가 상,하로 설치되어 서로 연통되어 있어 질산화부로 공급된 공기의 일부가 탈질부로 유입되므로 탈질부에서의 탈질효과가 저감되고, 질산화부로 유입된 하수는 블로워에 의하여 송출된 공기와 섞이면서 드래프트관을 통해 상승되어 순환되는 데, 상기 드래프트관 내에는 상기 탈질부(DN)로 유입되는 하수 교반용 임펠라을 회전시키기 위한 회전자가 설치되어 상기 드래프트관을 통해 상승하는 하수의 순환이 방해를 받게 되는 문제점이 있었다.The prior application discloses an invention which can achieve the functions of the conventional anaerobic tank, anoxic tank, aerobic tank and sedimentation tank by a single septic tank. However, the above-described invention of the invention is composed of the inner and outer cylinders, the denitrification unit (DN) to achieve the function of the anaerobic tank and the nitrification unit (OX) to achieve the function of the aerobic tank is installed up and down in communication with each other, so that the Part of the denitrification part is reduced, so the denitrification effect in the denitrification part is reduced, and the sewage introduced into the nitrification part is mixed with the air sent by the blower and is circulated up through the draft pipe, and the denitrification part (DN) in the draft pipe There was a problem that the rotor for rotating the impeller for the sewage agitation flowing into the) is installed to interfere with the circulation of sewage rising through the draft pipe.
특히, 상기한 선출원 발명은 외통내에 내통을 설치하여야 하기 때문에 그 제조작업이 복잡할 뿐만 아니라 내,외통의 측면부 사이에 침전실의 기능을 발휘하는 공간부를 형성하여야 하므로 외통의 직경이 증대되는 문제점이 있었고, 또한 탈질부의 저면이 질산화부와 직접 연통되어 있어 탈질부에서의 하수의 체류시간이 비교적 짧게되고 탈질부 및 질산화부에서 독자적인 기능을 발휘하는 미생물들이 서로 이동, 혼재되기 때문에 오, 폐수의 정화효율이 저감되는 문제점이 있었다.In particular, the above-described invention of the invention is not only complicated manufacturing work because the inner cylinder should be installed in the outer cylinder, but also needs to form a space between the sides of the inner and outer cylinders to function as a settling chamber, so the diameter of the outer cylinder is increased In addition, because the bottom of the denitrification part is in direct communication with the nitrification part, the residence time of the sewage in the denitrification part is relatively short and the microorganisms that have their own functions in the denitrification part and the nitrification part are moved and mixed with each other. There was a problem that the efficiency is reduced.
본 발명은 상기한 종래기술의 제반 문제점을 해결하기 위하여 안출된 것으로서, 하수의정화처리장치를 단순화하여 하수의정화처리장치의 제조 및 설치비용과 유지비용을 더욱 절감시키고 독자적인 기능을 수행하는 미생물들을 각각의 실에 고농도로 전속화시켜 하수의 정화처리효율을 향상시킬 수 있도록 한 하수의 질소, 인 제거장치를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above-mentioned problems of the prior art, by simplifying the sewage purification treatment apparatus to further reduce the manufacturing and installation cost and maintenance cost of the sewage purification treatment apparatus and perform microorganisms to perform their own functions It is an object of the present invention to provide a nitrogen and phosphorus removal device of sewage, which is capable of improving the efficiency of treatment of sewage by high concentration in each chamber.

순환실(D)로부터 질산화실(C)로 유입된 하수는 산기관(52)으로 부터 공기가 송출됨에 따라 공기와 접촉/혼합 되면서 기포의 상승력에 의해 상승관(22)을 따라 상승되어 배출구(23)로 배출된다.The sewage flowing into the nitric oxide chamber (C) from the circulation chamber (D) is lifted along the riser tube (22) by the lifting force of the bubbles while being contacted / mixed with the air as the air is discharged from the diffuser (52), and the discharge port ( 23).
한편, 배출관(64)을 통하여 배출되는 상등수는 그 일부가 분기관(65)을 통하여 용기(66)로 유입되고 용기로 유입된 하수는 송풍기(53)와 연결된 산기관(54)으로부터 공기가 송출됨에 따라 관로(67) 및 유입관(31)을 통해 탈질실(B)로 순환된다.Meanwhile, the upper portion of the supernatant discharged through the discharge pipe 64 is partially introduced into the container 66 through the branch pipe 65, and the sewage introduced into the container is discharged from the diffuser 54 connected to the blower 53. As it is circulated to the denitrification chamber (B) through the pipe line 67 and the inlet pipe (31).
상기와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
침사조에서 토사류등이 제거된 유입하수가 유입관(31)을 통하여 탈질실(B)로 공급될 때, 질산화실(C)의 호기성조건에서 하수에 함유된 질소가 산화태 질소로 산화되어 상승관(22), 배출구(23), 물받이통(44), 이송관(45), 순환관(33), 유도관체(34), 침전실(E), 월류벽(63), 분기관(65), 및 관로(67)를 순차적으로 통과하여 유입관(31)을 통해 유입하수와 함께 탈질실(B)로 공급되어 교반익부(43)의 회전에 의해 혼합되면서, 상기 산화태 질소는 탈질 미생물에 의해 환원되어 유출관(47)을 통해 질소가스 형태로 방출되므로 하수에 함유된 질소가 제거된다.When the inflow sewage from which the soils and the like are removed from the sedimentation tank is supplied to the denitrification chamber B through the inlet pipe 31, the nitrogen contained in the sewage is oxidized to nitrogen oxide under the aerobic condition of the nitrification chamber C. Pipe 22, outlet 23, drip container 44, transfer pipe 45, circulation pipe 33, guide pipe 34, sedimentation chamber (E), overflow wall (63), branch pipe (65) ), And sequentially passed through the pipe line 67 and supplied to the denitrification chamber B together with the inflow sewage through the inlet pipe 31 and mixed by the rotation of the stirring blade 43, the nitrogen oxide of the denitrification microorganisms. By reducing by being discharged in the form of nitrogen gas through the outlet pipe 47, the nitrogen contained in the sewage is removed.
그 다음, 하수는 월류벽(32)을 넘쳐흘러 순환관(33) 및 유도관체(34)를 통해 순환실(D)로 유입되는데, 순환실(D)로 유입된 하수는 통로(10a)를 통해 질산화실(C)로이송되고 그 중 일부는 침전실(E)을 따라 상승하면서 하수에 함유된 슬러지가 침강 분리되어 상징수가 월류벽(63)을 넘쳐흘러 배출관(64)을 통해 방류된다. 이때 배출관(64)을 통해 방류되는 상징수의 일부는 분기관(65), 관로(67) 및 유입관(31)을 통해 탈질실(B)로 순환된다.Then, the sewage flows over the overflow wall 32 and flows into the circulation chamber D through the circulation pipe 33 and the guide pipe 34, and the sewage introduced into the circulation chamber D passes through the passage 10a. The sludge contained in the sewage is sedimented and sedimented as the sludge contained in the sewage is sedimented and discharged through the discharge pipe 64 while some of the sludge is sedimented and separated. At this time, a part of the symbol water discharged through the discharge pipe (64) is circulated to the denitrification chamber (B) through the branch pipe (65), the pipe line 67 and the inlet pipe (31).
한편, 질산화실(C)의 산기관(52)으로 부터 공기가 송출됨에 따라 순환실(D)의 하수는 통로(10a)를 거쳐 질산화실(C)로 유입되어 공기와 접촉, 하수에 함유된 암모니아성 질소는 질산화 미생물에 의해 산화태 질소로 산화되면서 기포의 부력에 의해 상승관(22)을 따라 상승, 배출구(23)로 배출되어 회전익차(42)와 충돌하면서 회전익차(45)을 회전시키고 물받이통(44)으로 낙하되어 이송관(45), 순환관(33)을 따라 다시 순환실(D)로 순환된다.On the other hand, as the air is discharged from the diffuser 52 of the nitrification chamber C, the sewage of the circulation chamber D is introduced into the nitrification chamber C through the passage 10a to be in contact with air and contained in the sewage. As the ammonia nitrogen is oxidized to nitric oxide by the nitrifying microorganism, the buoyancy of the bubble rises along the riser 22 and is discharged to the discharge port 23 to collide with the rotor blade 42 to rotate the rotor blade 45. And fall to the drip tray 44 is circulated back to the circulation chamber (D) along the transfer pipe 45, the circulation pipe 33.
한편, 관로(46)가 간헐적으로 개방되어 잉여슬러지가 배출되는 데 질산화실(C)의 호기성 조건에서 인제거 미생물이 인을 다량 섭취한 상태에서 인제거 미생물이 포함된 슬러지가 베출되므로, 하수에 함유된 인이 제거된다.On the other hand, the pipeline 46 is intermittently opened to discharge excess sludge, but the sludge containing phosphorus-removing microorganisms is ejected in a state in which phosphorus-removing microorganisms ingest a large amount of phosphorus under aerobic conditions of the nitrification chamber (C). The phosphorus contained is removed.
이와같이, 본 발명은 탈질실(B) 및 질산화실(C)이 상하로 형성된 좌측통체(20)의 일측에 침전실(E)이 포함된 우측통체(20)가 부착 형성되므로, 내,외통으로 구성되어 탈질실, 질산화실 및 침전실이 단일조에 형성된 하수정화처리장치에 비해 그 제조작업이 간편함과 아울러 좌,우측통체의 직경이 축소되고, 탈질실(B)과 질산화실(C)이 독립되도록 구획됨과 아울러 탈질실(B)을 통과한 하수는 월류벽(63)을 넘쳐흘러 순환실(D)을 거쳐 질산화실(C)로 유입되므로 탈질실(B)에 있는 탈질 미생물은 질산화실로의 이동이 억제되므로 탈질 미생물이 탈질실(B)에 고농도로 전속되며, 질산화실(C)을 통과한 상징수가는 상승관(22), 유도관체(34), 침전실(E)을 거쳐 슬러지가 침강분리된 하수가 월류벽(63)을 넘쳐흘러 분기관(65), 관로(67)를 통해 탈질실(B)로 순환되므로 질산화 미생물은 탈질실(B)로의 이동이 억제되면서 질산화실(C)에 고농도로 전속되기 때문에 하수의 정화 효율이 향상되며, 송풍기(51)(53)에 의한 공기의 송출만으로 하수가 순환되고 배출구(23)로 배출되는 하수에 의하여 교반수단(40)이 회전되므로 하수정화처리장치의 시설비용 및 유지비용도 절감되는 효과가 있다.As described above, the present invention is attached to the right side cylinder 20 including the precipitation chamber E on one side of the left side cylinder 20 in which the denitrification chamber (B) and the nitric oxide chamber (C) are formed up and down. Compared to the sewage treatment system in which the denitrification chamber, the nitrification chamber and the precipitation chamber are formed in a single tank, the manufacturing work is simpler, and the diameter of the left and right cylinders is reduced, and the denitrification chamber (B) and the nitrification chamber (C) are independent. In addition, the sewage that passed through the denitrification chamber (B) overflows the overflow wall (63) and flows through the circulation chamber (D) to the nitric oxide chamber (C), so that the denitrification microorganisms in the denitrification chamber (B) are transferred to the nitrification chamber. Since the migration is suppressed, the denitrification microorganisms are transferred to the denitrification chamber (B) at a high concentration, and the symbol water passing through the nitrification chamber (C) is the sludge through the rising pipe (22), the induction pipe (34), and the settling chamber (E). The sedimentation sedimentation sedimented overflows the overflow wall (63) and circulates through the branch pipe (65) and the pipe line (67) to the denitrification chamber (B). Since organisms are transferred to the nitrification chamber C at a high concentration while the movement to the denitrification chamber B is suppressed, the purification efficiency of the sewage is improved, and the sewage is circulated only by the discharge of air by the blowers 51 and 53 and the discharge port ( Since the stirring means 40 is rotated by the sewage discharged to 23), the facility cost and maintenance cost of the sewage treatment apparatus are also reduced.
