매단 살수여상에 의한 오폐수처리장치 {Apparatus for treating wastewater by hanging trickling filter}Wastewater treatment apparatus by hanging water trick {Apparatus for treating wastewater by hanging trickling filter}

본 고안은 살수여상에 의한 폐수처리장치에 관한 것으로, 더욱 상세하게는 하수 및 오폐수 등을 생물막반응조를 이용하여 정화하는 오폐수처리장치에 관한 것이다.The present invention relates to a wastewater treatment apparatus using a spraying filter, and more particularly, to a wastewater treatment apparatus for purifying sewage and wastewater using a biofilm reactor.

오폐수처리방법중 살수여상법은 1차침전지의 유출수를 미생물로 된 점막으로 덮인 쇄석이나 기타 매개층 등의 접촉재 위로 뿌려져 생물막과 오폐수내의 유기물과 접촉시키는 고정상법에 의한 오폐수처리방법이다. 여기서 미생물 막층은 주로박테리아, 원생동물, 균류로 구성되며 환경이 양호한 경우에는 슬러지벌레, 파리의 유충 및 로티퍼(Rotifer)등의 고등동물이 존재하기도 한다. 또한 깊은 여상 바닥 부근에는 질산화 박테리아가 서식하여 질산화가 일어나는 경우가 많다. 살수여상은 호기성처리법으로 분류하지만 접촉재표면의 미생물막은 표층 0.1∼0.2mm만 호기성이고 그 내부는 혐기성이다. 이 방법은 부하변동에 대해 대응능력이 있고 슬러지 반송이 필요 없으며 슬러지발생량이 적다. 기타 포기에 동력이 필요 없다. 건설비와 유지비가 적게든다.Among the wastewater treatment methods, the sprinkling filter method is a method of treating wastewater by the fixed bed method in which the effluent of the primary sedimentation battery is sprayed onto contact materials such as crushed rocks or other intermediate layers covered with microbial mucosa and contacted with organic matter in the biofilm and wastewater. Here, the microbial membrane layer is mainly composed of bacteria, protozoa, and fungus. If the environment is good, there may be higher animals such as sludge worms, larvae of flies, and rotifers. In addition, nitrifying bacteria often inhabit nitrification near the bottom of the deep bed. The spraying water is classified into aerobic treatment method, but the microbial membrane on the surface of the contact material is aerobic only 0.1 ~ 0.2mm in the surface and the inside is anaerobic. This method is capable of responding to load fluctuations, does not require sludge conveyance and generates less sludge. No other abandonment requires power. Low construction and maintenance costs

운전이 간편하다. 슬러지벌킹의 문제가 없다는 반면에 접촉재의 깊이를 크게 하면 냄새가 발생하고, 폐쇄현상 등이 발하고 파리발생 등의 단점이 발생된다.Easy to drive While there is no problem of sludge bulking, increasing the depth of the contact material causes odor, closing phenomenon, flies, and so on.

또한 폐수처리장치(특허 제 0336263호)는 자연포기에 의한 다단식 구조로 되어 있어 처리효율은 우수하나 장치의 고층화로 인하여 설치가 어려운 단점이 있다.In addition, the wastewater treatment device (Patent No. 0336263) has a multi-stage structure by natural aeration, which is excellent in treatment efficiency but difficult to install due to the higher layer of the device.

본 고안은 하수 및 오폐수 등을 생물막반응조를 이용하여 순환 정화함으로써 오폐수의 정화효율을 현저히 증대시키면서 콤팩트화를 이루어 설치부지를 최소화한 오폐수처리장치를 제공함하고 기존 살수여상 방식에서 문제가 되었던 냄새발생, 여재의패쇄 및 파리발생을 방지하여 효과적으로 오폐수를 처리하는데 그 목적이 있다.The present invention provides a wastewater treatment device that minimizes the installation site by significantly compacting while circulating and purifying sewage and wastewater using a biofilm reactor, and generating odors, which have been a problem in the existing water treatment phase. The purpose of this is to effectively treat wastewater by preventing blockage and flies out of the media.

특히 본고안은 여재를 수직으로 매달아 공기중에 노출시킴으로써 기존 처리장이 고농도 오폐수처리시 자주 발생하는 여재폐쇄현상을 완전히 해소하였고 여재가 폐쇄되어 발생하는 냄새문제도 동시에 해결할 수 있다.In particular, this paper suspended the filter media vertically and exposed it to the air, and the existing treatment plant completely eliminated the filter media closing phenomenon that occurs frequently in high concentration wastewater treatment and solved the odor problem caused by the filter media closing.

In this case, the air contact biofilm 2 forms a biofilm in the form of a long string in which a contact medium that is conventionally used, that is, a thread of 0.1 mm or less, is stretched like a branch with a size of 4 cm. Air contact media can be suspended in any form of rope, triangle, etc., and materials can be used as long as they have durability such as polyethylene (PE) and polypropylene (PP).

그리고, 생물막반응조(12)에는 그 하부측에 수집호퍼(3)가 설치되어 공기접촉생물막(2)을 거친 정화폐수를 수집하여 침전조(8)로 낙하시키게 된다.In addition, the biofilm reaction tank 12 is provided with a collecting hopper 3 at the lower side thereof to collect the purified wastewater passing through the air contacting biofilm 2 and drop it to the settling tank 8.
