본 발명은 침전지와 생물여과지를 이용한 오폐수 처리장치에 관한 것이다.The present invention relates to a wastewater treatment apparatus using a sedimentation basin and a biofilter.

하천 및 호수로 유입되는 오염물질의 경우 점오염(point source) 보다 비점오염원(nonpoint source)에서의 유입이 많아 전체 유입량의 60~70%를 차지한다. 이러한 비점오염물질들은 강우에 의해서 유출되어 수원으로 유입되게 되는데 점 오염원에 비하여 제어하기가 매우 어렵다. Pollutants flowing into rivers and lakes account for 60-70% of the total inflow due to the inflow from nonpoint sources rather than point sources. These nonpoint pollutants are discharged by rainfall and flow into the water source, which is more difficult to control than point pollutants.

우리나라 대도시의 하수관거의 경우 대부분이 합류식으로 초기강우에 따른 오염물질의 유출이 발생하는데 이를 CSO(Combined Sewer Overflow)라 하며, 초기강 우에 의해 지표면의 오염물질과 합류식 하수관거 내에 침전되었던 오염물질이 동시에 유출되어 농도 및 부하가 매우 높은 것으로 알려져 있다. 이러한 이유로 우리나라 하수도 시설기준에서는 도 1 과 같은 개념으로 초기우수를 처리하도록 규정하고 있다. 즉, 강우가 발생하면 하수처리장을 유입되는 하수량이 증가하는데, 이때 하수처리장에서는 설계유량(Q)의 3배(3Q)에 해당하는 유량을 유입시켜 1차 침전지에서의 1차 침전을 거친 후 2Q는 방류하고 1Q만 생물반응조와 2차 침전지에서의 2차 처리를 거치도록 한다.Most of the sewage pipes of large cities in Korea are confluence, and the outflow of pollutants due to the initial rainfall is called CSO (Combined Sewer Overflow). It is known that the concentration and load are very high. For this reason, Korea's sewage facility standards stipulate to treat the initial rainwater with the same concept as in FIG. That is, when rainfall occurs, the amount of sewage flowing into the sewage treatment plant increases.In this case, the sewage treatment plant introduces a flow rate corresponding to three times the design flow rate (3Q) and undergoes the first precipitation at the primary sedimentation pond. Is discharged and only 1Q is subjected to secondary treatment in the bioreactor and the secondary settler.

그러나 유입 유량이 증가함에 따라 1차 침전지의 효율이 저하될 뿐만 아니라 하수처리장 슬러지 처리 계통에서 반송되는 고농도의 반류수가 유입하수로 유입되어 1차 처리수가 유입수에 비해 높은 농도를 나타내는 경우가 많아, 수계로 유입되는 오염물질을 양이 저감되는 것이 아니라 오히려 늘어나는 결과를 초래하였다.However, as the flow rate increases, the efficiency of the primary sedimentation basin not only decreases, but also the high concentration of return water returned from the sewage treatment plant sludge treatment system flows into the inflow sewage, so that the primary treated water shows a higher concentration than the inflow water. The amount of pollutants entering the plant was not reduced, but rather increased.

이러한 문제를 극복하고자 한국특허공개 제1999-0069310호(초고속 응집 침전형 오폐수 처리장치 및 이를 이용한 오폐수의 처리방법, 및 한국특허공개 제2000-0017670호(고속응집침전형 오폐수 처리장치)에서는 경사판이 도입된 고속응집 침전지를 이용하여 초기우수를 처리하도록 하였다. 도 2 는 이 특허에서 제시되어 있는 고속응집 침전지의 구조를 도시한 것으로서, 각 반응조는 혼화조, 교반조, 고분자응집조, 침전조로 순차 구성되어 있다. 이 특허는 응집제의 주입과 경사판의 도입을 통하여 부하 변동에 대한 대응이 우수하고 고형물 및 인제거 효과가 우수하나, 별도의 응집보조제로 아쿠아 219나 유리분말을 투입해야 하기 때문에 경제적으로 불리하고 운전관리가 용이하지 않을 뿐만 아니라 슬러지 생산량이 증가하는 단 점이 있었다. 특히 고속 응집 침전지는 고형물 및 인의 제거는 우수하나 용존오염물질(soluble pollutants) 및 질소의 제거가 거의 이루어 지지 않는 단점이 있었다.In order to overcome this problem, Korean Patent Publication No. 1999-0069310 (Ultra High Speed Coagulation Sedimentation Wastewater Treatment System and Treatment Method of Wastewater Using the Same), and Korean Patent Publication No. 2000-0017670 (High Speed Aggregate Sedimentation Wastewater Treatment System) Figure 2 shows the structure of the high-speed agglomerated sedimentation basin proposed in this patent, and each reaction tank is sequentially a mixing tank, a stirring tank, a polymer agglomeration tank, and a sedimentation tank. This patent is excellent in coping with load fluctuations through the injection of flocculant and the introduction of inclined plate, and it is excellent in solids and phosphorus removal effect, but it is economical because it needs to add Aqua 219 or glass powder as a separate flocculent aid. Not only is it disadvantageous and not easy to manage, but it also increases sludge production. Clarifier has had a disadvantage of being a solid and removing the solid one dissolved contaminants (soluble pollutants) and removal of the nitrogen does not substantially performed.

본 발명은 상기의 CSO 문제를 해결하고 특히 용존성 오염물질을 안정적으로 제거할 수 있으며, 잔류하는 응집성분을 재활용하여 침전효율을 증가시켜 후속되는 공정의 부하를 경감시킬 수 있는 오폐수 처리장치를 제공하는 것이다.The present invention solves the above CSO problem, and in particular, it is possible to stably remove the dissolved pollutants, and to provide a wastewater treatment apparatus that can reduce the load of the subsequent process by increasing the sedimentation efficiency by recycling the remaining aggregate components. It is.

본 발명에 따른 오폐수 및 초기우수 처리장치는 침전지(10)(1차 침전지), 생물반응조(20), 2차침전지(30) 및 생물여과지(40)를 순차 배치하여 구성된다.Wastewater and initial excellent treatment apparatus according to the present invention is configured by sequentially placing the sedimentation basin 10 (primary sedimentation basin), the bioreactor 20, the secondary sedimentation cell 30 and the biological filter paper (40).

침전지(10)는 기본적으로 도 2 에 도시되어 있는 전술한 경사판침전지와 동일하게 구성되어, 혼화조, 교반조, 고분자응집조와 침전조를 구비하고 있고, 침전조에는 경사판(11)이 구비되어 있다. 침전지(10)는 또한 자체의 반송관(13)(제1반송관)을 구비하고 있어 침전조의 유출 슬러지의 일부가 혼화조로 반송된다.The sedimentation basin 10 is basically configured in the same manner as the above-described inclined plate settling battery shown in FIG. 2, and includes a mixing tank, a stirring tank, a polymer aggregating tank and a settling tank, and the settling tank is provided with an inclined plate 11. The settling basin 10 also has its own conveying pipe 13 (first conveying pipe) so that a part of the outflow sludge of the settling tank is conveyed to the mixing tank.

2차침전지(30)는 유출 슬러지를 침전지(10)로 반송하는 반송관(33)(제2반송관)과 생물반응조(20)로 반송하는 반송관(35)(제3반송관)을 가지고 있다. 생물여과지(40)는 유출 슬러지를 침전지(10)로 반송하는 반송관(43)(제4반송관)을 가지고 있다.The secondary settling cell 30 has a conveying tube 33 (second conveying tube) for conveying the effluent sludge to the sedimentation basin 10 and a conveying tube 35 (third conveying tube) for conveying the bioreactor 20. have. The biofiltration paper 40 has a conveying pipe 43 (fourth conveying pipe) which conveys outflow sludge to the sedimentation basin 10.

또한, 침전지(10)와 생물여과지(40) 사이에는 처리수의 일부를 우회시키켜 생물여과지(40)로 공급하기 위한 우회관(17)이 마련되어 있다.In addition, a bypass tube 17 is provided between the settling basin 10 and the biological filter paper 40 to bypass a part of the treated water and to supply the biological filter paper 40.

초기강우에 의해 발생된 오염물질은 설계유량(Q)의 3배(3Q)로 경사판 침전지(10)로 유입된다. 경사판 침전지(10)로 유입된 폐수는 생물반응조(20)에서 반송관(35)을 통해 반송된 활성슬러지와 접촉하여 생물흡착이 발생하고, 경사판 침전지(10) 및 생물여과지(40)에서 각각 반송관(13, 43)을 통해 반송된 약품슬러지에 포함된 미사용된 응집제에 의해 응집이 이루어진다. 이때 고형물뿐만 아니라 용존성 오염물이 일부 흡착되어 제거된다.Pollutants generated by the initial rainfall flow into the swash plate settling basin 10 at three times the design flow rate Q. Waste water introduced into the swash plate settling basin 10 is in contact with the activated sludge conveyed through the conveying pipe 35 in the bioreactor 20, the biosorption occurs, and is returned from the swash plate settling basin 10 and the biofilter 40, respectively Agglomeration is achieved by the unused flocculant contained in the chemical sludge returned through the pipes 13 and 43. At this time, not only the solids but also the dissolved contaminants are adsorbed and removed.

이후 부족한 응집제와 응집보조제인 고분자응집제(폴리머)가 경사판 침전지(10)의 교반조와 고분자응집조에 각각 주입되어 응집 및 플럭을 형성하여 침전성을 개선한다. 그리고 나서, 오염물질은 경사판 침전지(10)의 침전조로 유입되어 침전을 통하여 처리수와 슬러지로 구분된다.Thereafter, the coagulant and the coagulant adjuvant polymer coagulant (polymer) are injected into the stirring tank and the polymer coagulation tank of the inclined plate settler 10, respectively, to form flocculation and floc to improve precipitation. Then, the contaminants enter the settling tank of the inclined plate settling basin 10 and is separated into treated water and sludge through the settling.

생물여과지(40)로부터 반송되는 생슬러지, 침전지(10)에서 자체 반송되는 일차슬러지, 및 침전지(10)와 생물여과지(40)에서 반송되는 약품슬러지가 혼합된 슬러지의 일부를 필요에 따라 반송하여 응집특성을 개선한다.The raw sludge returned from the biofilter paper 40, the primary sludge returned from the sedimentation basin 10, and a part of the sludge mixed with the chemical sludge conveyed from the sedimentation basin 10 and the biofilter 40 are carried out as necessary. Improve the cohesive properties.

침전지(10)의 처리수의 일부(1Q)는 생물반응조(20)로 유입되어 생물학적으로 질소, 인, 유기물을 제거한다. 생물반응조(20)에서 처리된 처리수는 2차침전지(30)로 유입되어 처리수와 슬러지를 분리한다.Part 1Q of the treated water of the sedimentation basin 10 is introduced into the bioreactor 20 to biologically remove nitrogen, phosphorus and organics. The treated water treated in the bioreactor 20 is introduced into the secondary settling cell 30 to separate the treated water and sludge.

침전지(10) 처리수의 일부(2Q)는 우회관(17)을 통해 바로 생물여과지(40)로 유입되어 고형물뿐만 아니라 용존성 유기물과 암모니아성 질소가 산화된다. 또한 생물여과지(40)에는 응집제를 투입하여 낮은 농도로 인 제거를 수행하게 되는데 주입된 응집제로 인한 슬러지를 생물여과지(40)에서 여과함으로써 인 제거가 이루어진다. 여과를 통하여 제거된 슬러지는 반송관(43)을 통해 1차 침전지(10)로 일부 반송하여 남아있는 응집능력을 재활용함으로서 약품소모량을 절감할 수 있다.Part of the treated water 2Q of the sedimentation basin 10 is directly introduced into the biofilter 40 through the bypass pipe 17 so that not only solids but also dissolved organic matter and ammonia nitrogen are oxidized. In addition, in the biofilter 40, a coagulant is added to perform phosphorus removal at a low concentration. The sludge due to the injected coagulant is filtered from the biofilter 40 so that phosphorus is removed. The sludge removed through the filtration may be partially returned to the primary settling basin 10 through the conveying pipe 43, thereby reducing the amount of chemical consumption by recycling the remaining cohesive capacity.

생물여과지(40)의 무산소지역에서는 생물반응조(20)에서 유입된 질산성 질소가 초기우수에 남아있는 용존성 유기물을 이용한 탈질반응을 통하여 제거된다. 생물여과지(40)의 호기지역에서는 잔류되는 유기물의 산화와 암모니아성 질소의 산화가 발생하여 수계로 유입되어 용존산소를 소모하는 물질의 안정적인 제거가 이루어져 강우시에도 수계로 유입되는 오염물질을 양을 최소화할 수 있다.In the anoxic region of the biofilter 40, nitrate nitrogen introduced from the bioreactor 20 is removed through denitrification using dissolved organics remaining in the initial rainwater. In the aerobic area of the biological filter paper 40, oxidation of residual organic matter and oxidation of ammonia nitrogen occur, and stable removal of substances consuming dissolved oxygen is introduced into the water system, thereby increasing the amount of pollutants introduced into the water system during rainfall. It can be minimized.

In addition, by returning a portion of the excess sludge and flocculation sludge generated in the biological process to the slant plate settling basin, the stable removal of dissolved pollutants by biosorption and the remaining flocculation component is recycled. Therefore, the sedimentation efficiency is increased to reduce the load of subsequent processes and to obtain stable treated water quality even when the load fluctuates severely.
