硅藻土微波改性及对污水中硫化物吸附的研究
Study on Adsorpting Sulfide of Diatomite Modified by Microwave and Vitriol
【摘要】 采用微波辐射技术及硫酸对硅藻土进行活化改性处理,研究了不同微波辐射时间、硫酸浓度、反应时间、硫酸与硅藻土的固液比等因素,对改性后硅藻土吸附水中硫化物效果的影响,并用改性硅藻土处理了生活污水,取得了很好的效果。试验结果表明,用微波及硫酸改性后,硅藻土对水中硫化物的吸附能力显著增强。
【Abstract】 The diatomite was modified with microwave and vitriol. Our tests researched effect of adsorpting sulfide in wastewater at different microwave radiation time, vitriol concentration, vitriol reaction time and rate of vitriol and diatomite. The better affection can be got by modified diatomite,and the results showed that adsorption capacity of diatomite modified by vitriol and microwave was much increased.
