본 발명은 유류의 흡착능이 우수한 오염물질 제거용 고성능 흡착 신소재와 이 소재를 이용한 유류 흡착튜브장치 및 이 장치를 이용한 오염수의 정화방법에 관한 것이다. 더욱 상세하게는, 유류의 흡착능이 우수한 오염물질 제거용 고성능 흡착 신소재와, 이 소재를 이용한 수동식 유류 흡착장치와 자동식 유류 흡착장치 및 이들 장치를 이용한 오염수의 유류성분만을 선택적으로 제거하는 오염수 정화방법에 관한 것이다.The present invention relates to a high-performance adsorption new material for removing pollutants with excellent oil adsorption capacity, an oil adsorption tube device using the material, and a method for purifying contaminated water using the device. More specifically, a new high performance adsorption material for removing contaminants with excellent oil adsorption capacity, a manual oil adsorption device and an automatic oil adsorption device using the material, and a contaminant purification to selectively remove only oil components of contaminated water using these devices. It is about a method.

기존의 자유상(free phase oil)으로 오염된 오염수 및 지하수의 복원기술은 자유상을 회수할 수 있는 다양한 형태의 고가의 스키머(skimmer)를 사용하거나, 양수처리(pump & treat method)한 오염지하수를 유수 분리장치를 통과시켜 자유상 물질을 정화하는 방법을 사용하였다.Conventional free phase oil contaminated water and groundwater restoration technology uses various types of expensive skimmers or pump & treat methods to recover free phase. Groundwater was passed through an oil-water separator to purify free phase material.

오염지하수의 자유상물질을 회수하기 위한 종래의 스키머 등은 추출정당 1기씩 설치하여 장기간 운영하여야 하며, 자유상 물질뿐만 아니라 물도 함께 회수되기 때문에 별도의 유수 분리장치를 필요로 하는 문제점이 있다. 또한, 오염지역이 광범위하거나, 자유상물질의 막이 얇은 경우에는 적용할 수 없는 단점이 있다. 이러한 특징 때문에 다수의 소규모 오염지역을 동시에 복원하거나 대규모 오염지역을복원하기 위해서는 다량의 설비들이 장기간 소요되는 특성 때문에 많은 복원비용이 소요되는 문제점이 있다. 따라서, 별도의 유수 분리장치나 스키머등을 사용하지 않고 자유상으로 오염된 오염수 및 지하수로부터 자유상 물질을 효과적으로 회수할 수 있는 복원장치 및 방법이 확립되어야 할 필요성이 대두되고 있다.Conventional skimmers for recovering free phase material of contaminated groundwater have to be installed for 1 long period per extraction well, and there is a problem in that a separate oil water separation device is required because not only the free phase material but also water is recovered together. In addition, there is a disadvantage that can not be applied when the contaminated area is wide or the film of the free phase material is thin. Because of this feature, there is a problem in that a large number of facilities are required for a long time in order to restore a large number of small contaminated areas at the same time or restore a large contaminated area. Therefore, there is a need to establish a recovery apparatus and method capable of effectively recovering free phase materials from contaminated water and groundwater contaminated freely without using a separate oil-water separator or skimmer.

실시예 1 : 본 발명 친유성 유류 흡착소재의 제조와 최적 제조온도의 확인Example 1 Preparation of the Invention Lipophilic Oil Adsorption Material and Confirmation of Optimum Manufacturing Temperature

볏짚, 왕겨, 폐펄프, 톱밥, 및 목편(wood chip)을 혼합한 것을 회전식 탄화장치에서 질소가스를 공급하여 혐기적 조건을 유지하면서 탄화온도를 200∼600℃로 변화시켜 20분 동안 탄화시켰다. 여러 온도에서 탄화과정을 통해 얻은 친유성 유류흡착 소재의 유류흡착능과 수분흡착능을 조사하였다(도 4). 유류흡착능은 디젤유를 사용하여 조사하였다. 유류 흡착소재의 유류흡착량은 200∼400℃까지 28g/g으로 변화가 없었고, 400℃ 이상의 탄화조건에서 감소하였다. 반면, 수분 흡착율은 200℃에서 1g/g으로 측정되다 300℃이후의 온도에서는 0.2g/g이하로 나타나지 않았다. 결과적으로 유류 흡착량은 많으면서 수분을 흡착하지 못하는 300∼400℃사이의 온도가 최적의 친유성 소재의 제조온도임을 밝혔다.Rice straw, rice husk, waste pulp, sawdust, and wood chips were mixed in a rotary carbonization apparatus and supplied with nitrogen gas to change the carbonization temperature to 200-600 ° C. while maintaining anaerobic conditions and carbonized for 20 minutes. The oil adsorption capacity and water adsorption capacity of the lipophilic oil adsorption material obtained through the carbonization process at various temperatures were investigated (FIG. 4). Oil adsorption capacity was investigated using diesel oil. The oil adsorption amount of the oil adsorption material was unchanged to 28 g / g from 200 to 400 ° C, and decreased under carbonization conditions of 400 ° C or higher. On the other hand, the moisture adsorption rate was measured at 1 g / g at 200 ° C. and did not appear below 0.2 g / g at temperatures after 300 ° C. As a result, it was found that the temperature between 300 and 400 ° C., which is high in oil adsorption and unable to adsorb moisture, is the optimum temperature for manufacturing lipophilic materials.

The performance was evaluated. The adsorption tube was recovered between about 10 minutes and 5 hours after the adsorption tube was added. The recovered oil adsorption tube was injected into a vacuum apparatus (20 cm in diameter and 40 cm in length) to remove free phase material adsorbed on the tube, and the regenerated tube was reintroduced into the groundwater extraction well to repeatedly remove the oil from the extraction well. Even when the adsorption tube was regenerated and used repeatedly for about 10 times, the amount of oil adsorption was confirmed to adsorb about 7,200-7,750 g of free phase material.
