Abstract：

To　analyse　the　optimal　condition　of　photocatalytic　removal　of　indoor　air　contaminant　by　air　cleaner,　an　experimental　system　of　photocatalytic　degradation　of　HCHO　was　constructed　and　two　photocatalytic　TiO2　films　were　coated　by　dipping　method　on　the　granular　active　carbon　and　the　netlike　active　carbon,　respectively.　The　results　showed　that　the　photocatalytic　removal　of　HCHO　was　controlled　by　mass　transfer　process　and　photocatalytic　reaction　process　in　the　higher　HCHO　concentration,　and　the　photocatalytic　reaction　switched　from　mass　transfer　process　to　photocatalytic　reaction　process　with　the　increasing　of　flow　velocity,　and　the　removal　of　HCHO　by　TiO2　film　coated　on　netlike　active　carbon　was　higher　than　that　coated　on　granular　active　carbon.　However,　in　the　lower　HCHO　concentration,　the　removal　of　HCHO　was　reduced　with　the　increase　of　flow　rate　for　the　residence　time　of　HCHO　on　the　surface　of　TiO2.　Those　experimental　results　were　useful　to　the　application　of　photocatalytic　technology.
