【摘要】 本文以酸性大红染料模拟印染废水,采用改性粉煤灰作为吸附剂,探讨粉煤灰改性类型及其投加量、反应温度、吸附时间、反应pH值、废水浓度、废水中NaCl含量等因素对模拟废水脱色效果的影响规律及吸附脱色效果,为粉煤灰处理印染废水的工程实践提供理论依据。更多还原

【Abstract】 In this paper,acidic scarlet dyestuff simulated printing and dyeing wastewater was used as adsorbent,and modified fly ash was used as adsorbent. The effects of modification type of fly ash and its dosage,reaction temperature,adsorption time,reaction pH value,concentration of wastewater and NaCl content in wastewater on decolorization efficiency of simulated wastewater and adsorption decolorization effect were discussed. It provides theoretical basis for the engineering practice of treating printing and dyeing wastewater.更多还原
