某矿山属于含砷难处理金矿,需要采用高压预氧化或生物预氧化工艺对矿石进行预处理后,才能实现金的高效回收。矿山现场水质盐度高,Cl-浓度高,需对其淡化处理后才能用于矿石的氧化处理工艺中。膜技术应用于水处理领域,相比传统技术具有处理效率高、成本低的优势;通过对现场水质的综合分析和针对性的系列试验,结果表明,不用化学预处理除钙镁,膜技术可以直接实现矿区盐水的有效脱盐,满足提金的生产需求。盐水采用电渗析处理后,产水Cl-质量浓度可控制在1.5 g/L,满足生物预氧化对水质的要求,淡水回收率为60%,吨水能耗约为6.

考察了厌氧氨氧化(Anammox)污泥对不同盐度的响应以及添加不同外源物质对盐度抑制的缓解效果。首先采用连续流试验考察了0~20 g/L NaCl对UASB反应器脱氮性能的影响,其次采用短期批次试验考察了投加KCl、FeSO4、甘氨酸甜菜碱(C5H11NO2) 3种外源物质对盐度抑制Anammox脱氮性能及污泥活性的缓解作用。结果显示,未经驯化的Anammox污泥对环境较敏感,6 g/L盐度即可显著抑制其脱氮性能;随驯化过程进行,Anammox污泥能逐渐适应15 g/L的盐度;在盐度为20 g ...
