[발명이 속하는 기술분야 및 그 분야의 종래기술][Technical Field to which the Invention belongs and Prior Art in the Field]
본 발명은 하수 등의 각종 유기성 오수를 매우 합리적인 처리방법 및 장치에 의하여 생물학적으로 고도로 정화처리하는 유기성오수의 처리방법 및 그 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating organic sewage and a device for biologically highly purifying various organic sewage such as sewage by a very reasonable treatment method and apparatus.
종래, 유기폴리머화합물로 이루어진 입자형상물을 미생물고정화담체(이하 단순히"담체(擔體)"라고 칭함)로서 이용하여, 오수를 정화하는 데에는 처리조내에 용적의 5∼70% 상당량의 담체를 침지투입하고, 처리조내에 산기(散氣)·회류(回流)를 행하고, 당해 담체를 자유로이 이동시켜서 피처리수를 접촉시키는 유동상자에 의하고 있다.Conventionally, a particulate material made of an organic polymer compound is used as a microbial fixation carrier (hereinafter simply referred to as a "carrier"), and a 5 to 70% equivalent amount of carrier is immersed in a treatment tank to purify sewage. This is based on a flow box in which an acid group and a return flow are performed in the treatment tank, and the carrier is freely moved to contact the water to be treated.
종래의 유동상자로 유기성오수를 정화할 경우는, 피처리수와 함께 담체를 회류하기 때문에 큰 동력을 필요로 함과 동시에, 회류시에 담체는 처리조 벽에 쓸려서 마모가 심하여 내구성이 부족한 문제가 있었다.In the case of purifying organic wastewater with a conventional flow box, since the carrier is flowed together with the water to be treated, it requires a large power, and at the time of return, the carrier is swept away from the treatment tank wall and wears badly, resulting in insufficient durability. There was.

따라서, 상기 제1실시형태 및 제5실시형태에 의한 발명은 호기처리조내의 담체가 담체의 통과를 저지하는 그물형상체로 구획되어 있기 때문에, 각 실에 담체층이 형성된다. 담체는 부양상태이지만 상하의 그물형상체의 구획내에 있으며 이동이 없다.Therefore, in the inventions according to the first and fifth embodiments, the carrier layer is formed in each chamber because the carrier in the aerobic treatment tank is partitioned into a net-like body that prevents the passage of the carrier. The carrier is in a floating state but is in the compartments of the upper and lower reticulated bodies and there is no movement.
또한, 조내에서 피처리수가 순환하기 때문에 유기불순물을 호기분해하는 담체층을 수회 통과하므로, 담체 내외의 미생물의 접촉 회수가 늘어 정화가 촉진된다. 그물형상체 및 담체는, 산기 및 피처리수의 흐름으로 막힘이 방지된다.In addition, since the water to be treated circulates in the tank, it passes through the carrier layer that aerobicly decomposes organic impurities, so that the contact number of microorganisms inside and outside the carrier increases, thereby promoting purification. Reticulated bodies and carriers are prevented from being blocked by the flow of acid groups and water to be treated.

The tank has the same function as the embodiments of the present invention, and flows the water to be processed from the treatment tank at the foremost part to the treatment tank at the rear part in order to increase the number of microorganisms in the carrier layer to increase the treatment capacity. have.
또한, 상기 제3 및 제7실시형태에 의한 발명은 제2 및 제6실시형태에 의한 발명과 마찬가지의 기능을 갖는데, 호기처리조가 수개의 처리조로 간막이되어 있는 경우, 각 처리조에서 순환을 받은 피처리수가 최후방부의 조에서 순환을 받은 후, 피처리수의 일부가 최전방부의 처리조로 재차 반송되어 되풀이 정화처리를 받으므로, 호기분해를 보다 효율적으로 행할 수 있다.In addition, the invention according to the third and seventh embodiments has the same function as the invention according to the second and sixth embodiments. When the aerobic treatment tank is partitioned into several treatment tanks, the treatment tank receives circulation in each treatment tank. After the water to be treated is circulated in the rearmost tank, a part of the water to be treated is returned to the treatment tank in the foremost portion and subjected to repeated purification treatment, whereby aerobic decomposition can be performed more efficiently.
또, 제4 및 제8실시형태에 의한 발명은 호기처리조내의 담체가 담체의 통과를 저지하는 그물형상체로 구획되어 있기 때문에, 각 방에 담체층이 형성되고, 담체는 부양상태이지만 상하의 그물형상체의 구획내에 있으며 이동이 없다. 또, 그물형상체 및 담체는 산기 및 피처리수의 흐름으로 막힘이 방지 되는 것은 마찬가지이지만, 각 조의 유기불순물을 호기분해하는 담체층을 통과한 후 최후방부의 피처리수의 일부가 최전방부의 처리조로 재차 반송되어 되풀이 정화처리를 받으므로, 각 처리조내에서 피처리수를 순환시키는 것과 마찬가지로 호기분해를 효율적으로 행할 수 있다.Further, according to the fourth and eighth embodiments of the present invention, since the carrier in the aerobic treatment tank is partitioned into a net-like body that prevents the passage of the carrier, a carrier layer is formed in each room, and the carrier is in a floating state, but the upper and lower nets are formed. It is in the compartment of the upper body and there is no movement. In addition, although the reticulated bodies and the carrier are prevented from being blocked by the flow of the acid groups and the treated water, a part of the treated water in the rearmost part is treated in the foremost part after passing through the carrier layer that aerobicly decomposes each group of organic impurities. Since the tank is returned to the tank again and subjected to repeated purification treatment, aerobic decomposition can be efficiently carried out in the same manner as circulating the water to be treated in each treatment tank.
[실시예]EXAMPLE
이하, 본 발명의 1실시예를 도면에 의거하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described based on drawing.
제1도는 본 발명의 제1 및 제 5실시형태에 의한 실시예를 나타낸 구성도이며, 제2도는 제2, 제3 및 제 6, 제7 실시형태의 실시예를 나타낸 구성도이다.1 is a configuration diagram showing an example according to the first and fifth embodiments of the present invention, and FIG. 2 is a configuration diagram showing an example of the second, third, sixth, and seventh embodiments.
제1도에 있어서 도면중(1)은 호기처리조이고, 호기처리조(1)내에 수평으로 그물형상체(2)가 가로 설치되어서, 상부실(1A), 중앙부실(1B), 하부실(1C)로 구획되어 있다.In FIG. 1, 1 is an aerobic treatment tank, and the mesh-like body 2 is horizontally installed in the aerobic treatment tank 1, and the upper chamber 1A, the central chamber 1B, and the lower chamber ( 1C).
도면에서는 3단으로 구획되어 있지만 단층 또는 다층의 방으로 구획할 수도 있다.Although it is divided into three stages in the figure, it can also be divided into a single | mono layer or a multilayered room.
상부실(1A)과 중앙부실(1B) 및 하부실 (1C)내에는 피처리수중에 포함된 유기불순물을 호기분해하는 호기성 미생물을 지닌 부상성을 가진 담체(3)가 느슨하게 다수 충전된 담체층이 형성되어 있다.In the upper chamber 1A, the central chamber 1B, and the lower chamber 1C, a carrier layer loosely filled with a floating carrier 3 having aerobic microorganisms that aerobicly decomposes organic impurities contained in the water to be treated. Is formed.
상기 그물형상체(2)의 그물코는 담체(3)의 통과를 저지하는 크기로 형성되어 있고, 담체(3)는 실내로부터 나오는 일은 없다.The mesh of the said net-shaped body 2 is formed in the magnitude | size which prevents the passage of the support | carrier 3, and the support | carrier 3 does not come out from the room | chamber.
담체(3)는 부상성을 가진 입자형상체이면 특히 소재는 제한되지 않으나, 유기폴리머 화합물의 발포체 또는 가공품 등 공지의 것을 사용할 수 있는데, 그 중에서도 소재 자체에 적당한 탄성과 강도를 가진 소재가 바람직하고, 특히 우레탄수지 등이 바람직하다.The carrier 3 is not particularly limited as long as the carrier 3 is a floating body, but known materials such as foams or processed articles of organic polymer compounds may be used. Among them, a material having a suitable elasticity and strength for the material itself is preferable. In particular, urethane resins are preferable.
예컨대 주원료인 폴리올의 고분자 고리가 에테르결합으로 이루어진 연질 폴리우레탄폼 등의 탄성 다공성 입자형상물을, 우레탄수지등의 플라스틱을 연이어 통하는 기포를 만드는 발포법으로 발포하여 만들어서, 소망하는 형상사이즈로 절단하여서 사용한다.For example, an elastic porous granular material such as a flexible polyurethane foam in which a polymer ring of a polyol, which is a main raw material, is made of ether bonds, is foamed by a foaming method for forming a bubble through a plastic such as urethane resin, and cut into a desired shape size. do.
그 사이즈는 10∼30㎜이고, 그 형상은 각형, 볼형, 기타 여러 가지 형상을 채택할 수 있는데, 각형이 바람직하다.The size is 10-30 mm, and the shape can adopt a square shape, a ball shape, and other various shapes, A square shape is preferable.
에테르계의 연질 폴리우레탄폼을 사용하면, 가수분해를 받기 어렵고 내구성도 충분히 있는 동시에, 내면 및 외면의 기공이 서로 연이어 통하고 있으므로, 미생물은 담체의 내부로 잠입하기 때문에 배양이 용이하고, 피처리수나 공기류에 의하여 미생물이 박리하지 않는다.When ether-based flexible polyurethane foam is used, it is difficult to be hydrolyzed and sufficiently durable, and since the pores on the inner and outer surfaces are connected to each other, microorganisms are easily incubated into the carrier, making it easy to cultivate and to be treated.

[발명의 효과][Effects of the Invention]
본 발명에 의하면, 담체는 부양상태이지만, 상하의 그물형상체의 구획내에 있으며, 피처리수만이 담체 사이를 통과하기 때문에 회류(回流)에 의한 담체의 마모가 없고, 내구성을 가진다. 그리고, 그물형상체를 다층으로 하여 담체를 나누고 있기 때문에 담체가 갖는 부력 및 중량에 의하여 그물형상체가 파손하는 일이 없고 안전하다. 또, 담체를 회류하지 않으므로 호기처리조로의 초기의 투입에 즈음하여, 미생물의 증식이 없더라도 순양(馴養)의 필요가 없음과 동시에, 담체의 투입량도 호기처리조 용적의 30∼80%의 용적분에 상당하는 양으로 되고, 호기분해능력을 현격하게 향상할 수 있다.According to the present invention, the carrier is in a floating state, but is located in the upper and lower sections of the net-shaped body, and since only the water to be treated passes between the carriers, the carrier is not abraded by flow and has durability. Since the carrier is divided into multiple layers of the net body, the net body is not damaged by the buoyancy and the weight of the carrier and is safe. In addition, since the carrier is not circulated, the initial introduction into the aerobic treatment tank eliminates the need for pure volume even without the growth of microorganisms, and the amount of the carrier is also 30 to 80% of the volume of the aerobic treatment tank. It becomes the quantity equivalent to and can improve aerobic decomposition ability remarkably.
또, 피처리수는 담체층을 되풀이해서 통과히기 때문에 효율적으로 호기처리를 받을 수 있는 것이다.In addition, since the water to be treated passes through the carrier layer repeatedly, it can be efficiently subjected to aerobic treatment.
