실시 예2> 휘발성유기화합물(VOCs) 제거 효율의 측정. Example 2 Determination of Volatile Organic Compound (VOC s ) Removal Efficiency.
상기 실시 예를 통해 제조된 폴리우레탄 폼 담체를 실험장치를 통해 도 6a와 같이 하루 24시간씩 총 68일 동안 운전하였으며, 이때 유입되는 벤젠의 농도 범위는 약 50 내지 400ppmv로 점차 증가시켰으며, 공탑체류시간(Empty bed residence time)은 3분으로 운전하였다. 유입부와 유출부의 벤젠 농도를 GC-FID(HP 6890 series)로 측정하여 처리효율을 알아보았다.The embodiment was operated for a gun 68 days 24 hours a day, such as 6a through the prepared polyurethane foam carrier experimental apparatus through, wherein the concentration range of the benzene entering the stylized gradually increased to about 50 to 400ppm v, Empty bed residence time was operated for 3 minutes. Benzene concentrations at the inlet and outlet were measured by GC-FID (HP 6890 series) to determine the treatment efficiency.
그 결과 도 6b에 도시된 바와 같이, 벤젠의 처리 효율이 95% 이상을 나타내는 결과를 얻을 수 있었으며, 벤젠 유입의 농도가 급격히 증대될 때 일부 70%대로 낮아지는 경향을 보였지만 전체적으로 양호한 처리 효율을 보임을 알 수 있었다.As a result, as shown in FIG. 6B, the results showed that the treatment efficiency of benzene was 95% or more, and when the concentration of benzene inflow was sharply increased, it showed a tendency to be lowered to some 70%, but the overall treatment efficiency was good. And it was found.
상기와 같이 구성된 본 발명은, 각종 하 · 폐수 처리 공정에서 발생되는 슬러지를 200 내지 550℃에서 탄화시킨 탄화물을 폴리우레탄 프리폴리머 수용액에 혼합한 후, 이에 계면활성제를 첨가하여 악취물질 처리용 다공성 폴리우레탄 폼 담체를 제조함으로써, 미생물 부착효율이 뛰어나고, 내구성이 강화되며, 고농도의 악취물질과 휘발성유기화합물을 효율적으로 처리할 수 있는 효과가 있다.The present invention configured as described above, after mixing the carbide carbonized sludge generated in various sewage and wastewater treatment process at 200 to 550 ℃ in a polyurethane prepolymer aqueous solution, and added a surfactant to the porous polyurethane for treating odorous substances By producing a foam carrier, the microbial adhesion efficiency is excellent, durability is enhanced, and there is an effect that can efficiently process high concentration of odorous substances and volatile organic compounds.
또한, 표면적 확대물질로는 산업공해를 야기시키는 슬러지를 탄화시킨 탄화물을 사용함으로써, 산업부산물의 재활용도를 증대시킬 수 있을 뿐만 아니라, 환경보호 측면에 있어서도 유익을 도모할 수 있는 또 다른 효과가 있다.In addition, the use of carbide carbonized sludge that causes industrial pollution as a surface area expansion material can not only increase the recycling degree of industrial by-products, but also have other effects that can be beneficial in terms of environmental protection. .
