title: [Abilities of acetaldehyde removal in different water-treating techniques].
abstract: The effect of acetaldehyde removal by several kinds of water-treating technologies is experienced in laboratory and the results reveal that traditional water-treating processes have hardly any useful results and the absorption of GAC does no better either for its efficiency depending on the GAC service time greatly and with a very short leakage time. However, the micro-biological degradation process in the BAC filter can consume more than 95% acetaldehyde in 13 minutes when the biomass has been fully acclimatized. The acclimation process usually lasts 4-30 h under field conditions depending on the stabilization and maturity of the original biomass on the carbon, but can be shortened remarkably by means of inhibiting the activity of existing biomass or artificially inoculating acclimatized microbe.
