Abstract
본 발명은 오·폐수 고도 처리용 판 접촉재의 제조방법에 관한 것으로서, 종래의 말굽형 막대로된 접촉재는 격자형으로 적층 사용되는 것이므로 시간이 갈수록 오니의 퇴적현상이 심하고 부패현상이 초래되어 수처리가 잘 안되는 경향이 있다.The present invention relates to a method of manufacturing a plate contact material for advanced wastewater treatment, and the contact material made of a conventional horseshoe-shaped bar is used in lamination in a lattice form, so that the sedimentation of sludge is severe and rot occurs over time. It tends to be bad.
따라서, 본 발명은 PP 나 PE 와 수거된 폐비닐수지를 혼합하여 2~3 mmΦ크기로 입자화한 주원료와 황토,제올라이트, 규조토, 세라믹, 활성탄, 숯분말의 부원료를 1:0.05~0.2 범위내에서 혼합하는 제1공정과; 200~450℃의 가열온도로 매회 3~10분 범위내에서 3회 용융 또는 탄화시키는 과정을 행하는 제2공정과; 상기 탄화 용융된 주/부 원료를 0.01~0.03m/sec 의 압출속도와 150~300 Ton/㎠ 의 압력으로 판재 형상으로 압출 성형하는 제3공정으로 판접촉재를 생산하는 것으로서, 이러한 판접촉재는 미생물이 부착되는 메디아의 비표면적과 공극율이 크기 때문에 부착되는 미생물을 고농도로 증식시킬 수 있고, 부착 미생물의 중량을 지탱하는 강도가 뛰어나며, 세정시 담체 사이에 부착된 SS의 박리성이 뛰어나고 자연스러워 부착 생물막의 퇴적 등에 의한 부패 현상이 없어 정화능력이 향상되는 것이다.Therefore, the present invention is mixed with PP or PE and the collected waste vinyl resin, the main raw material and ocher, zeolite, diatomaceous earth, ceramic, activated carbon, charcoal powder granulated into 2 ~ 3 mm Φ within the range of 1: 0.05 ~ 0.2 Mixing with the first step; A second step of performing melting or carbonizing three times within a range of 3 to 10 minutes each time at a heating temperature of 200 to 450 ° C; The plate contact material is produced by a third process of extruding the carbonized molten main / sub raw material into a plate shape at an extrusion speed of 0.01 to 0.03 m / sec and a pressure of 150 to 300 Ton / cm 2.

Description
본 발명은 오·폐수 고도 처리장치에 설치되는 판접촉재의 제조방법에 관한 것으로서, 특히 PP(Poly Propylene)나 PE(Poly Ethyene)와 폐비닐 입자를 주원료로 하여 가격이 저렴하면서도 생산이 용이하고, 오·폐수의 접촉면적을 확대시켜 처리효율을 증대시킬 수 있는 오·폐수 처리용 판접촉재의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a plate contact material is installed in the advanced wastewater treatment device, in particular, PP (Poly Propylene) or PE (Poly Ethyene) and waste vinyl particles as a main raw material, while being cheap and easy to produce, The present invention relates to a method of manufacturing a plate contact material for wastewater treatment, which can increase the treatment efficiency by expanding the contact area of wastewater.
일반적으로 우리나라는 수질오염의 주범이라고 할 수 있는 염색 및 도금공장, 피혁처리공장이 많고, 또한 젖소 및 돼지를 사육하는 축산농가가 많은 편이다.그러므로 대단위 아파트 단지에서 배출되는 생활하수와 분뇨정화조에서 나오는 각종 오수 및 각종 산업폐수와 축산폐수(이하 오·폐수 라 칭함) 등에는 상당량의 질소(T-N)와 인(T-P)성분이 함유되어 있다고 할 수 있다.In general, Korea has many dyeing and plating plants and leather processing plants, which are the main culprit of water pollution, and also many livestock farms that raise cows and pigs.Therefore, domestic sewage and manure septic tanks discharged from large apartment complexes The various sewage, industrial wastewater and livestock wastewater (hereinafter referred to as “wastewater”) that is released contain a considerable amount of nitrogen (TN) and phosphorus (TP) components.
그러므로 이러한 오·폐수에는 하천이나 해안을 오염시키는 유기물질과 색도가 다량 함유되어 있어서 이를 제대로 정화하지 않고 그대로 방류하면 심한 적조현상이 발생하고, 물고기가 떼죽음을 당하는 등 생태계가 심하게 파괴되는 현상이 발생된다.Therefore, such waste water contains a large amount of organic substances and colors that pollute rivers and coasts. If this is not properly cleaned, it can cause severe red tide and severe ecosystem destruction such as fish being killed. do.
따라서, 이러한 환경오염 때문에 각종 오·폐수는 항시 정수처리를 하여 생물학적 산소요구량(BOD)을 최대한 낮춘 상태로 배출하도록 법으로 규제하고 있으며, 이를 충족시키기 위하여 각종 오·폐수를 배출하는 공장이나 대단위 아파트 단지 등에는 오·폐수 정화용 처리시설을 의무적으로 설치하여야만 한다.Therefore, due to such environmental pollution, various wastewater and wastewater are regulated by law to discharge water at the lowest possible level by treating water at all times, and to meet this, factories or large apartments emitting various wastewater and wastewater The complex, etc., must be equipped with a treatment facility for wastewater purification.
상기 오·폐수 처리장치중 일례로 유량조정조-→폭기조-→생물막조-→ 침전조-→침전처리수조-→여과조-→방류조를 거쳐 방류하는 타입이 있고, 또는 집수조-→1차침전조-→여과조-→처리수조-→접촉산화조-→ 최종침전조-→방류조를 거쳐 방류하는 타입 등 여러가지가 있으며, 상기 침전조에서 침전된 오니 슬러지와 여과조에서 걸러진 오니 슬러지는 오니농측저류조에 모아지도록 구성되어 있다.One example of the wastewater treatment system is a type of discharge control tank- → aeration tank- → biofilm tank- → sedimentation tank- → sedimentation treatment tank- → filtration tank- → discharge tank, or collecting tank- → primary sedimentation tank- → There are various types of discharged through filtration tank- → treatment tank- → contact oxidation tank- → final sedimentation tank- → discharge tank, and sludge sludge precipitated in the sedimentation tank and sludge filtered from the filtration tank are collected to be collected in the sludge concentration storage tank. have.
그리고, 상기 탈질조, 폭기조, 침전조, 여과조 등에는 노화 퇴적된 미생물군의 자동 탈락을 유도하고 호기성 미생물의 용이한 활착 및 배양효율을 높히기 위하여 표면에 담체입자가 부착된 접촉제를 주로 사용하고 있다. In addition, in the denitrification tank, aeration tank, precipitation tank, filtration tank, etc., a contact agent having carrier particles attached to the surface is mainly used to induce automatic dropping of the aging-deposited microbial group and to increase the swelling and culture efficiency of aerobic microorganisms. .
즉, 오·폐수는 정화 처리를 함에 있어서 호기성, 혐기성 처리 또는 통성 혐기성 처리과정을 거치게 되는데, 이때 접촉제가 없으면 부유 미생물에 의해 처리하게 되고, 부유 미생물은 계속 유입되는 오·폐수에 의해 씻겨 내려가기가 쉬우므로 일정한 농도의 미생물 농도를 유지해 주기가 어렵게 된다.In other words, the waste water is subjected to aerobic, anaerobic, or anaerobic anaerobic treatment in the purification process. At this time, the contactant is treated by suspended microorganisms, and the suspended microorganisms are washed down by the influent wastewater. Easy to maintain a constant concentration of microorganisms is difficult to maintain.
따라서, 이러한 점을 보완하고 부착 성장생물막법으로 유도하기 위해서는 접촉재의 사용이 필수적이라고 할 수 있는데, 도 1 에서와 같이 종래의 접촉제(1)는 대부분 말굽형의 막대형이고, 주원료인 폐합성비닐에 부원료인 모래와 활성탄 및 여과사를 혼합하여 만들어진 고다공질형의 접촉제이다.Therefore, the use of a contact material is essential in order to supplement this point and lead to the attached growth biofilm method. As shown in FIG. 1, the conventional contact agent 1 is mostly a horseshoe-shaped rod and a main raw material, waste synthesis. It is a highly porous type contact agent made by mixing vinyl as a raw material, sand, activated carbon, and filtration sand.
그런데, 상기 말굽형의 막대기처럼 만들어진 종래의 접촉재(1)는 상기 처리조에서 도 2 와 같이 단순히 격자형으로 적층시켜 쌓은 상태로 설치 사용되는 것이므로 하부에서 공기를 산기관에 의해 공급할 경우 처음 초기에는 잘 되지만 시간이 갈수록 오니의 퇴적현상이 심하여져 막히는 현상(폐쇄현상)이 발생되어 부패현상이 초래되고 결국 수처리(정화)가 잘 안되는 경향이 있다.By the way, the conventional contact material (1) made of a horseshoe-shaped bar is installed in a state in which the lattice is simply stacked and stacked as shown in FIG. Although it works well in time, sedimentation of sludge becomes more severe and clogging occurs (closure), which leads to corruption, and eventually water treatment (purification) tends to be poor.
실제로 상기와 같이 오·폐수 처리장치를 설치한 여러 하수처리장에서는 상기한 종래 말굽형 접촉제(1)의 부패현상이 자주 발생하는 말썽을 일으켰으며, 이를 위해 설치업체는 막대한 비용을 투자하여 말굽형 접촉재(1)를 전량 교체해 주어야만 하는 현상까지 발생하였다. In fact, in the various sewage treatment plants in which the waste water treatment system is installed as described above, the above-mentioned decay phenomenon of the conventional horseshoe type contact agent 1 is often caused, and for this purpose, the installation company invests a huge amount of horseshoe type. There was even a phenomenon in which the entire contact material 1 had to be replaced.
따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 개발된 것으로서, 본 발명의 목적은 비표면적과 공극율이 크고 상당 중량의 생물이 부착되더라도 그 무게를 충분히 지탱할 수 있는 인장 강도를 가질 수 있으며, 생물막의 탈부착이 자연스러워 부착생물막의 퇴적 등에 의한 부패 현상이 없고 정화능력이 뛰어난 오·폐수 고도 처리용 판접촉재의 제조방법을 제공하는데 있다.Therefore, the present invention has been developed to solve the above-mentioned conventional problems, the object of the present invention can have a tensile strength that can sufficiently support the weight even if a large specific surface area and porosity is attached to a large weight of organisms The present invention provides a method for manufacturing a plate contact material for advanced treatment of wastewater and waste water, which has a decomposing phenomenon due to the deposition and deposition of adherent biofilms due to the natural detachment and detachment of biofilms.

PP(Poly Propylene)나 PE(Poly Ethyene) 또는 수거된 폐비닐수지(고합성수지)를 분쇄기에서 2~3mmΦ크기로 분쇄하여 입자화(Pellet化)된 주원료를 준비하고, 또한 황토,제올라이트(Zeolite), 규조토, 세라믹, 활성탄, 숯분말을 배합한 부원료를 준비한다.Pelletized main raw materials are prepared by grinding PP (Poly Propylene) or PE (Poly Ethyene) or collected waste vinyl resin (high synthetic resin) into 2 ~ 3mm Φ in the grinder, and also ocher, zeolite Prepare the subsidiary materials containing diatomaceous earth, ceramic, activated carbon and charcoal powder.
그 후 상기 분쇄된 주원료와 부원료를 1:0.05~0.2 범위내에서 배합기에서 배합하는데 그 배합비는 상황에 따라 약간(±0.02)의 범위내에서 변할 수 있다. 이는 여재의 인장강도나 취성, 공극율 등이 서로 유기적인 관계에 있기 때문이다.Thereafter, the pulverized main raw materials and the sub raw materials are blended in a blender within a range of 1: 0.05 to 0.2, and the blending ratio may vary within a range of (± 0.02) depending on the situation. This is because the tensile strength, brittleness, and porosity of the media are in an organic relationship with each other.
제2공정(용융 또는 탄화공정)2nd process (melting or carbonization process)
상기 혼합된 주원료와 부원료를 용융 또는 탄화시키는 과정을 행하는데, 이때 가열온도는 200~450℃가 적당하고, 대부분 3회 정도의 탄화 또는 용융과정을 거치게 하며, 매 회의 용융 또는 탄화시간은 3~10분 범위내에서 탄력적으로 적용한다. 이때, 제1단계서는 주/부 자재의 절반정도가 탄화되게 하고, 제2단계서는 90% 의 탄화가 이루어지게 하며, 3단계서는 용융과정이 완료되게 함을 특징으로 한다.The process of melting or carbonizing the mixed main and sub-materials is carried out, in which the heating temperature is 200 ~ 450 ℃ is suitable, and most of the three times the carbonization or melting process, each time melting or carbonizing time is 3 ~ Apply flexibly within 10 minutes. At this time, the first stage is about half of the main / secondary material is carbonized, the second stage is characterized in that the carbonization of 90%, the third stage is characterized in that the melting process is completed.
제3공정(압출 및 인발 성형공정)3rd process (extrusion and drawing molding process)
상기 3회에 걸쳐서 탄화 또는 용융된 주/부 원료를 압출기로 보내어 압출 성형한다. 이때 압출속도는 압출 스크류가 싱글이냐 더블이냐에 따라 또는 구경에 따라 다르게 선정되지만 대부분 0.01~0.03m/sec 정도의 압출속도로 압출하는 것이 바람직하다.The carbonized or molten main / secondary raw material is sent to the extruder and extruded three times. At this time, the extrusion speed is different depending on whether the extrusion screw is single or double, or depending on the diameter, but most preferably extruded at an extrusion speed of about 0.01 ~ 0.03m / sec.
그리고, 압출때는 150~300 Ton/㎠ 의 압력으로 압출하는 것이 바람직하며, 대기중으로 인발되어 나오면 온도차, 기압차 또는 냉각수에 의해 팽창되면서 그 표면이 터지고 요철부분이 많아지게 되면서 본 발명의 판접촉재 성형이 완성되는 것이고, 그 후 성형된 판접촉재의 냉각 및 절단공정을 거쳐 포장 출하하면 본 발명의 판접촉재 생산에서부터 포장까지의 과정이 완료된다.And, when extruding, it is preferable to extrude at a pressure of 150 ~ 300 Ton / ㎠, and when drawn out into the air as the temperature difference, pressure difference or cooling water is expanded, the surface of the plate and the uneven portion increases the plate contact material of the present invention Molding is completed, and then packaged and shipped through the cooling and cutting process of the molded plate contact material is completed from the plate contact material production to the packaging of the present invention.
이러한 본 발명의 판접촉재는 경사형으로 적층 설치되거나 또는 수직으로 설치 가능한 것으로서, 미생물이 부착되는 메디아의 비표면적과 공극율이 크기 때문에 부착성장 또는 번식하는 미생물에 대해 매우 안정적이면서도 고농도로 미생물을 증식시킬 수 있는 효과가 있으며, 부착된 생물의 중량이 상당하더라도 그 무게를 충분히 지탱할 수 있는 강도가 있어서 내구성이 뛰어나다.The plate contact member of the present invention can be stacked or installed vertically or be installed vertically, and because the specific surface area and porosity of the media to which the microorganisms are attached are large, the microorganisms can grow microorganisms at a high concentration and high concentration against microorganisms that adhere or grow. There is an effect that can be, even if the weight of the attached organisms is significant enough to support the weight of the durability is excellent.
또한, 여과저항이 적고 SS 제거능력이 뛰어나며, 세정시 담체 사이에 부착된 SS의 박리성이 뛰어나고 자연스러워 부착 생물막의 퇴적 등에 의한 부패 현상이 없으며, 세정에 필요한 동력이 전혀 필요없고 오·폐수에 혼입 유입된 영양염류 또는 유기물 질소, 인 등을 섭취시켜서 이들 불순물을 용이하게 제거시켜 주므로서 물의 정화능력이 향상되는 효과가 있다.In addition, it has low filtration resistance, excellent SS removal ability, excellent peelability of SS adhered between carriers during cleaning, and no spoilage due to deposition of attached biofilm, and does not require any power for cleaning and By ingesting nutrients or organic matter nitrogen, phosphorus, and the like introduced and mixed, it is possible to easily remove these impurities, thereby improving the water purification ability.
