光伏太阳能产业主要以太阳能电池产品为主,在生产过程中产生了大量的含氟废水.目前含氟废水主要采用化学沉淀法进行处理,但是这种单一的方法难以实现出水氟离子质量浓度＜ 10 mg/L的国家工业废水排放标准.针对某实际工程,通过将化学沉... 详细信息

光伏太阳能产业主要以太阳能电池产品为主,在生产过程中产生了大量的含氟废水.目前含氟废水主要采用化学沉淀法进行处理,但是这种单一的方法难以实现出水氟离子质量浓度＜ 10 mg/L的国家工业废水排放标准.针对某实际工程,通过将化学沉淀法与絮凝沉淀法相结合的两级处理工艺,串联处理太阳能电池生产过程中产生的含氟废水,在以pH值控制在8～ 12之间为基础条件的情况下,最终实现氟离子质量浓度由进水的400 mg/L下降至8mg/L,低于国家工业废水排放标准对氟离子的排放要求.

采用溶胶凝胶法制备了Ti1-xCrxO2±δ体系系列样品.利用扫描电子显微镜(SEM),X射线光电子能谱(XPS),粉末X射线衍射分析(XRD)方法研究了Ti1-xCrxO2±δ系列样品的颗粒尺寸、形貌、组分化学态、相关系和固溶区范围;并利用超导量子干涉磁强计对样品的磁性能进行了研究.采用Rietveld结构精修的方法研究了Cr的不同掺杂量对TiO2晶体结构的影响,研究表明,1000℃烧结的样品的固溶区范围是x=0—0.03,为金红石单相;随着Cr掺杂量的增加,金红石相晶胞参数规律性地减小;当x>0.03,为金红石相和CrO2相两相共存.综合XRD和磁性测量结果,500℃烧结的样品的固溶区范围是x=0—0.02,为锐钛矿单相;随着Cr掺杂量的增加,锐钛矿相晶胞参数规律性地减小;当x≥0.04,为锐钛矿相和绿铬矿相(Cr2O3)两相共存.XPS实验结果表明,500℃和1000℃退火的样品中Cr都是以Cr+3和Cr+6两种化学态存在,1000℃烧结的样品中可能有更多的Cr3+转化为Cr6+.根据M-H和M-T曲线的测试结果发现,本文500℃烧结的Ti1-xCrxO2±δ体系样品当x=0—0.02时,为室温铁磁性.当x≥0.04时,由铁磁相和顺磁相所组成,在低温下有较强的铁磁性;室温下主要是顺磁相,铁磁相只占据很小的体积分数.
