Abstract
본 발명은 포름알데히드을 함유한 폐수처리방법에 관한 것으로, 폐수에 소석회를 중량%로 0.05-0.15%투입하고, 이를 70-90℃온도로 유지시킴으로서 포름알데히드를 당의 유사물질인 포르모스로 전환시킨 뒤, 현탁증식법 또는 부착증식법의 생물학적 처리방법을 이용하여 유기물을 제거함과 더불어 펜톤방법을 추가로 실시하여 난분해성인 색소를 제거함과 더불어 폐수중의 포름알데히드의 독성에 기인한 폐수처리의 어려움을 제거하여 상태계에 미치는 악영향을 크게 감소시킬수 있도록 되어있다.The present invention relates to a method for treating wastewater containing formaldehyde, and converting formaldehyde to formmos, a sugar-like substance, by adding 0.05-0.15% of slaked lime to the wastewater in weight percent and maintaining it at a temperature of 70-90 ° C. In addition, the organic matter is removed by biological treatment method such as suspension proliferation or adhesion proliferation, and the Fenton method is additionally used to remove hardly degradable pigments and to treat wastewater due to the toxicity of formaldehyde in the wastewater. By removing it, it is possible to greatly reduce the adverse effect on the state machine.
