Gongye shui chuli, 2012 介绍了一种测定工业循环冷却水中钼酸盐含量的方法———硫氰酸盐分光光度法。在待测水样中加入6.0 mL硫酸溶液,1.0 mL硫酸亚铁铵溶液,10.0 mL硫氰酸铵溶液以及1.0 mL抗坏血酸溶液,此时钼酸盐被还原成Mo5+,并与硫氰酸盐形成橙色络合物,在460 nm波长处测定该络合物的吸光度并通过标准曲线计算出钼酸盐含量。该方法科学、稳定,抗干扰能力强,测定范围适用于循环冷却水中钼酸盐含量的测定。

Gongye shui chuli, 2017 考察了不同硫酸盐浓度对好氧反硝化菌铜绿假单胞菌CP1反硝化过程的影响。结果表明，随着硫酸盐浓度的增加，菌株CP1反硝化时间逐渐缩短，脱氮速率加快，硫酸盐为300 mg/L，菌株CP1获得最优的脱氮效果；当硫酸盐增加到750 mg/L时，反硝化时间大大延长，脱氮速率降低。在硫酸盐为450 mg/L时，菌株获得最大的脱氮速率，可达到48.83 mg/（L·h）。在0~1 200 mg/L硫酸盐质量浓度范围内，出水均无NO2--N累积。硫酸盐含量在整个反硝化过程中无明显变化。

硫酸盐还原——甲烷发酵两步厌氧法处理含高浓度硫酸盐有机废水可行性研究
Gongye shui chuli, 1993 本文以合成废水为基质,采用软性纤维填料反应器和UASB反应器,研究了硫酸盐还原作用与甲烷发酵相结合的两阶段厌氧消化工艺处理含高浓度硫酸盐有机废水的可行性,并探讨了处理系统的最佳工艺条件。研究表明,反应器通过18天的启动,硫酸盐的去除率可达到95％;硫酸盐还原的同时有机物被酸化,酸化产物以乙酸为主;废水pH在6.48-7.14时,反应器可获得最高的硫酸盐去除率并使出水中硫酸盐浓度在国家规定标准以下。

Gongye shui chuli, 2020 采用正交实验方法，探讨了过二硫酸盐用量、硫酸亚铁用量、初始pH及反应时间4个工艺参数对亚铁-过二硫酸盐法深度氧化处理造纸废水（二级生化出水）效果的影响。结果表明：过二硫酸盐用量为436 mg/L，亚铁用量为654 mg/L，原水基础上微调或不调初始pH，反应30 h，为处理效果最优工艺条件。经亚铁-过二硫酸盐法处理后上清液CODCr去除率可达90%，色度去除率可达97%。与Fenton法相比，亚铁-过二硫酸盐法在处理效果及经济成本上具有明显优势，应用前景良好。
