Abstract

본 고안은 미생물 번식구슬에서 번식되는 미생물을 연속적으로 공급시켜 폐수 정화를 향상시키는데 있다. 현재 사용하는 폐수 처리장은 공기 폭기조내에서 공기 폭기로 산소공급을 하여 정화조(폭기조)내의 탁도가 높으며 폐수 량과 온도에 따라 미생물 증식에 적합하기도 하고 적합지 못 할 때도 있어 [도6]에서 보기같이 미생물 수가 변화되어 정화상태가 양호와 불량을 반복한다. 미생물 증식구슬은 맥반석의 분쇄 미세 가루를 5m/m크기로 환을 지어 다시 구워만든 구슬(BIO CERAMIC)은 수 만개의 기공으로 되어있어 미생물 증식에 최우수 품목이다. 현재 이 구슬을 폐수처리에 널리 사용하지 못한 것은 폐수 찌꺼기가 구슬외부에 붙어 쌓이면 구슬 내의 미생물이 외부로 나오지 못하여 사용이 어려웠다. 이 점을 감안하여 본 고안은 미생물 증식조 내에 수 백 만개의 구슬을 넣고 이 구슬을 이동 시키면서 구슬과 구슬을 마찰시키는 회전 스크류를 장착하여 회전시키면 구슬외부에 그 찌꺼기가 끼지 못하여 미생물 통로가 항상 열리고 마찰로 인해 구슬 마모 편에는 많은 미생물이 함유되어 배출시킨다. 미생물 증식조에는 고밀도 미생물이 번식하므로 양분과 충분한 산소 공급이 요구되며 미생물 번식에 적합한 온도가 요구된다. 양분은 폐수자체이고 산소는 산소 용해장치에서 공급되며 온도 조절은 온도 조절기에서 행하여 항시 고밀도 미생물을 증식시켜 정화조로 공급되어 정화조 내에서 번식되는 미생물 수가 적을 때에도 정화조내의 고밀도 미생물 수를 유지시켜 폐수 상태에 관계없이 항시 정화능력이 우수하다. 공기 폭기가 없어 침전지를 별도로 설치하지 않아도 침전지와 정화조를 하나로 통합시켜 설치 면적이 반감되면서도 고밀도 미생물 유지로 정화능력이 항상 우수하다.The present invention is to improve the waste water purification by continuously supplying microorganisms propagated in the microbe propagation beads. The currently used wastewater treatment plant has a high turbidity in the septic tank (aeration tank) by supplying oxygen to the air aeration tank in the air aeration tank, and may not be suitable or suitable for microbial growth depending on the amount and temperature of the wastewater. The number is changed so that the purification state is good or bad. BIO CERAMIC is the best item for microbial growth because the microbial growth beads are made by re-baking crushed fine powder of elvan rock in 5m / m size. Currently, the beads have not been widely used for wastewater treatment, and when the wastewater residues are attached to the outside of the beads, the microorganisms in the beads are difficult to use. In light of this, the present invention puts millions of beads in the microbial growth tank and rotates them by rotating a rotating screw that rubs the beads with the beads while moving the beads. Because of the friction, the bead wear contains many microorganisms and is released. As the microorganism propagation tanks grow high density microorganisms, they need nutrients and sufficient oxygen supply, and a temperature suitable for microbial propagation is required. Nutrient is the wastewater itself, oxygen is supplied from the oxygen dissolving device, and temperature control is carried out by the temperature controller, and the high-density microorganism is always multiplied and supplied to the septic tank to maintain the high-density microorganism count in the septic tank even when the number of microorganisms propagated in the septic tank is maintained. Regardless of its ability, it has excellent purifying ability at all times. Even though there is no air aeration, the sedimentation basin and the septic tank are integrated into one unit to reduce the installation area and maintain high density microorganisms.

Description

미생물 증식조{BIO - REACTOR}Microbial growth tank {BIO-REACTOR}

종래의 폐수 처리는 [도5]와 같은 시스템으로 유입수(12)는 1차 침전지(32)를 거처 폭기조(34)에는 미생물이 배양되며 공기방울(36)에 의해 폭기를 시키면서 산소를 공급하는 관계로 폐수의 와류 때문에 2차 침전지(37)를 거쳐야 유출수로 처리되어 시설면적이 많으면서 미생물(8b)증식이 적합 할 때도 있고 적합하지 못 할 때도 있어 미생물 수(44)의 상태가 [도6]과 같이 진행되어 유출수(42)의 B.O.D 가 양호와 불량으로 이어진다. 본 고안을 폐수처리 시스템에 접목 시키면 [도3]과 같은 시스템의 폐수처리장이 된다. 정화 침전지(13)은 정화조내 증식 미생물(8b)와 공급받는 미생물(8a)에 의해 고밀도 미생물이 유지되며 용해 산소물(27)에 의해 산소를 공급 받으므로 물의 와류도 없고 충분한 산소 관계로 침전지와 폭기조를 합한 정화 침전지(13)가 되어 시설비도 적으면서 정화능력이 우수하다. 미생물 증식조(30)의 운전은 [도3]에서 보면 산소용해기(26)는 산소발생기(24)에서 발생되는 산소를 공급받고 유입폐수는 물 펌프(23)에 의해 산소용해기(26)를 통과되면 고농도 산소 용해수(27)가 되어 일부는 정화침전지(13)으로 보내고 일부는 물 온도 히터(28)를 통과되어 히팅된 물은 물 펌프(29)에 의해 미생물 증식조(30)내의 미생물 증식 구슬(5)를 통과하면서 미생물(8)을 증식시켜 공급되므로 정화 침전지(13)의 미생물(8a,8b)이 항상 많이 유지되어 정화능력이 우수하다.Conventional wastewater treatment is a system as shown in FIG. 5 inflow water 12 is the primary sedimentation basin 32 through the aeration tank 34, the microorganisms are cultured and aeration by air bubbles 36 while supplying oxygen Due to the vortices of the wastewater, it is treated as effluent only through the secondary sedimentation basin 37 so that the growth of the microorganism 8b is sometimes appropriate or sometimes not suitable because the facility area is large. Proceeding as follows, the BOD of the effluent 42 leads to good and bad. When the present invention is combined with the wastewater treatment system, it becomes a wastewater treatment plant of the system as shown in FIG. Since the high-density microorganism is maintained by the proliferating microorganism 8b and the supplied microorganism 8a in the septic tank, and the oxygen is supplied by the dissolved oxygen 27, the clarification basin 13 has no vortex of water, It is a purification sedimentation basin 13 which combined the aeration tank, and it is excellent in purification ability with little facility cost. Operation of the microbial growth tank 30 is an oxygen dissolver 26 is supplied with oxygen generated from the oxygen generator 24 and the incoming wastewater is oxygen dissolver 26 by the water pump 23 as shown in FIG. When passing through the high concentration oxygen dissolved water (27), and part of it is sent to the purifier settling 13, and some of the water passed through the water temperature heater 28 is heated by the water pump 29 in the microbial growth tank 30 Since the microorganism 8 is multiplied and supplied while passing through the microorganism propagation beads 5, the microorganisms 8a and 8b of the purified sedimentation basin 13 are always maintained, so that the purification ability is excellent.

현재 사용되는 폐수처리 공정은 폐수의 탁도와 량, 폭기조 내의 온도, 산소의 용해도에 따라 폭기조 내에서 미생물의 생장과 사멸을 폐수장 상태에 따를 수 밖에 없었으나 본 고안은 외부에서 미생물 증식을 시켜 항시 우수한 정화능력을 유지시키는데 있다.Currently used wastewater treatment process has no choice but to follow the growth and killing of microorganisms in the aeration tank depending on the turbidity and quantity of the wastewater, the temperature in the aeration tank and the solubility of oxygen. Maintains excellent purifying ability.

본 고안은 미생물 증식구슬(5)의 겉표면에 증식 미생물(8a)의 출구통로인 구슬내의 구멍(7)을 폐수 찌꺼기가 막지 못하게하여 미생물증식 구슬(5)의 내부에서 증식되는 증식 미생물(8a)이 항시 유출 시키도록 한 구조로서 미생물 증식조 통(1)내에 미생물 증식구슬(5)을 가득 채우고 회전축(3)을 중심에 둔 경사 나선형판(4)을 회전모터(2)로 회전시키면 미생물 증식구슬(5)이 이동 되면서 서로 마찰을 일으킨다. 이 마찰로 구슬 마모 가루(5a)가 생기고 산소 용해기(26)를 통과한 물은 온도 히터(28)을 지나면서 온도가 조절된 고농도 산소용해수(10)은 미생물증식 구슬(5) 사이를 통과하면서 충분한 산소 공급을 시켜주고 증식 미생물(8a)가 많은 구슬마모가루(5a)를 정화 침전지(13)로 공급시켜주는 미생물증식조The present invention prevents wastewater residues from blocking the holes 7 in the beads, which are the exit passages of the microorganism propagation beads 5, on the outer surface of the microbial propagation beads 5, thereby proliferating inside the microbial propagation beads 5a. ), The microbial growth vessel (1) is filled with the microbial growth beads (5), and the inclined spiral plate (4) centered on the rotating shaft (3) is rotated by the rotary motor (2). Proliferation bead (5) is moved to cause friction with each other. This friction produces the bead wear powder 5a, and the water passing through the oxygen dissolvers 26 passes through the temperature heater 28, and the high-concentration oxygen-dissolved water 10 whose temperature is controlled is passed between the microbe-growing beads 5. A microbial growth tank that supplies sufficient oxygen while passing and supplies bead abrasion powder (5a) containing a lot of proliferating microorganisms (8a) to the purification sedimentation basin (13).

기존 폐수 처리장의 침전지와 폭기조내에서 미생물이 증식되며 적정한 산소 농도와 미생물의 적정 온도가 알맞을 때도 있고 불량 할 때도 있어 폐수의 정수능력을 가진 미생물이 적을때는 정화능력이 떨어진다. 본 고안은 주위환경 여건에 구애 받지 않고 항시 고밀도 미생물을 증식 공급시켜 정수 능력이 우수하여 기존 폐수 정화시설에 비해 시설면적이 적으면서도 폐수처리가 우수하다.Microorganisms multiply in the sedimentation basins and aeration tanks of existing wastewater treatment plants, and the appropriate oxygen concentration and the appropriate temperature of the microorganisms may be appropriate and sometimes poor. The present invention is excellent in water purification ability by proliferating and supplying high density microorganisms at all times regardless of the surrounding environment, and it has excellent facility for treating wastewater while having less facility area than existing wastewater purification facilities.
