The peroxone process overcomes many of the limitations associated with conventional and advanced water treatment systems using chlorine disinfection and ozone oxidation processes. Ozone and hydrogen peroxide generate highly reactive hydroxyl free radical which oxidize various organic compounds and h...

정수처리에서 peroxone 공정은 수중의 이취물질과 합성 유기화합물과 같은 유기성 오염물질의 산화 제거를 목적으로 적용되었다
. Geosmin과 2-MIB 같은 이취물질들은 오존 산화에 대해 내성을 가지지만 peroxone 공정에서는 효과적으로 제거가 가능한 것으로 보고되고 있으며,21,37∼39) 1,1-dichloropropene, TCE, PCE, 1-chloropentane 및 1,2-dichloroethane과 같은 염소계 유기화합물들의 산화제거에도 오존공정 보다 peroxone 공정이 효과적인 것으로 보고되 었다.핵심어 | 질문 | 논문에서 추출한 답변 |

우리가 제조하여 사용하는 합성 유기물질들이 엄청난 증가 추세를 보이고 있는 이유는? | 정수처리 공정에서 염소와 오존 같은 산화제는 바이러스나 원생동물의 불활성화 및 수중의 난분해성 물질의 산화목적으로 사용되어져 오고 있다.1,2) 산업의 발전과 생활수준의 향상으로 우리가 제조하여 사용하는 합성 유기물질들은 엄청난 증가 추세를 보이고 있으며3) 이러한 합성 유기물질들은 대부분이 난분해성으로 환경에 심각한 위해성을 나타낸다. 이런 물질들은 하·폐수 처리장 유출수 및 침출수 등에서 완전히 제거되지 못하고 상수원으로 유입되어 우리들의 건강을 위협한다. | |
합성 유기물질들이 환경에 심각한 위해성이 되는 이유는? | 1,2) 산업의 발전과 생활수준의 향상으로 우리가 제조하여 사용하는 합성 유기물질들은 엄청난 증가 추세를 보이고 있으며3) 이러한 합성 유기물질들은 대부분이 난분해성으로 환경에 심각한 위해성을 나타낸다. 이런 물질들은 하·폐수 처리장 유출수 및 침출수 등에서 완전히 제거되지 못하고 상수원으로 유입되어 우리들의 건강을 위협한다.4∼10) 난분해성 오염물질들은 농약류, 합성 세제, 색도 유발물질, 의약물질들 및 내분비계 장애물질들 등으로11∼14) 염소나 오존을 이용해서 이러한 물질들을 효과적으로 산화 제거하기에는 한계가 있다. 산화효율 증진을 위해 과다한 염소의 투입은 트리할로메탄과 같은 소독부산물을 과다하게 생성시키며 또한, 과다한 오존투입의 경우도 비경제적이다. |
