| Abstract: | Composite process composed of urea condensation-fly ash adsorptionFenton oxidation was researched experimentally for pretreatment of high-level formaldehyde wastewater.The influencing factors were investigated and the optimal working condition was found.By this way the strength of the crude wastewater with high concentration formaldehyde was decreased evidently,the degradation rate of formaldehyde is above 99%.It is believed that this will be quite favorable for the further biological treatment. |
