Abstract
In the paper, the organic wastewater from petrol chemical plant is treated by modified fly ash three by different methods from an electric power plant.The removal rate of COD and ammonia -nitrogen is measured to evaluate the effect of treat-ment.And active carbon is used as a reference.The level of fly ash and systemic temperature are researched to investigate the treatment effect.The results show that the best treatment effect appeared when the level of fly ash reached 15 -20g /L.As for sys-temic temperature, the adsorption capacity of all those adsorbents is increased and then decreased as the temperature increased , at about 20 ℃ to achieve the best value.The systemic temperatures affect ammonia nitrogen removal evidently more than the COD re -moval.the best kind of modified fly ash evaluated by wastewater treatment effect is the fly ash modified by mixed roasting with Na -CO3 and H2 SO4 acidification treatment, COD removal rate can reach 76.9%, than that of the unmodified 9.8%, the ammonia ni-trogen removal rate is up to 35.9%, than that of the unmodified 32.8%, and compared with the same content of activated carbon on the ammonia the removal efficiency can be higher.关键词
