为探究铝铁含量和孔隙结构对水厂污泥吸磷的作用,对水厂铁污泥和铝污泥的铝铁含量进行了检测,对其吸磷前后的孔隙结构和比表面积进行了分析,定量分析污泥吸磷前后微孔结构的变化。结果表明,水厂污泥主体孔径为介孔,直径4.0 nm左右的孔隙对污泥比表面积贡献最大。铁污泥和铝污泥BET模型比表面积分别为62.46、242.42 m2/g,铝、铁的质量分数分别为22.64%和11.96%,对磷的饱和吸附量分别为22.64、18.56 mg/g。吸附磷后2种污泥的比表面积都有下降,铝铁含量高比表面积小的污泥对磷的吸附量高于比表面积大铝铁含量低的污泥,这表明污泥吸附磷不仅受比表面积大小的影响,而且与其中的铝铁含量密切相关。

目的:探讨二甲双胍干预奥氮平所致精神分裂症患者糖脂代谢异常和体质量增加的效果。方法:将2015年2月—2016年4月收治的精神分裂症患者116例,以随机数字表法分为观察组和对照组,每组58例。对照组患者采用奥氮平单药治疗,观察组患者在对照组基础上给予二甲双胍进行干预,两组患者均治疗16周,治疗期间对失眠者可短暂给予苯二氮类药物治疗。比较两组患者治疗过程中恶心、血糖升高、头晕等不良反应发生率,治疗前后空腹血糖、总胆固醇、三酰甘油水平及体质量指数、生活质量评分的差异。结果:治疗过程中,观察组患者恶心、血糖升高、头晕等不良反应总发生率明显低于对照组,差异有统计学意义(P0.05);与治疗前比较,治疗后观察组患者空腹血糖、总胆固醇、三酰甘油水平及体质量指数无明显变化,而对照组患者上述指标显著升高,差异均有统计学意义(P0.05);治疗后,观察组患者生活质量评分显著优于对照组,差异有统计学意义(P<0.05)。结论:二甲双胍可有效降低奥氮平所致精神分裂症患者糖脂代谢异常和体质量增加的发生率,维持患者糖脂水平和体质量的稳定,避免因体质量急剧增加和糖脂水平升高而增加患者心脑血管疾病发生风险,促进患者生活质量的提高。
