, 2009 用0.01、5.00mg/L微囊藻毒素-RR(MC-RR)处理反硝化细菌,研究了MC-RR对反硝化细菌的生长、培养液中NO3--N和NO2--N含量以及细胞内硝酸还原酶活性的影响。结果表明,高浓度MC-RR能显著抑制反硝化细菌的生长,延缓其细胞增殖,抑制培养液中硝酸盐含量的降低和亚硝酸盐含量的升高以及细胞内硝酸还原酶的活性,因而可能抑制或减缓生态系统中氮循环的进程。这表明 ...

Gongye shui chuli南方离子型稀土矿通常采用硫酸铵作浸矿剂进行提取开采，矿山开采后的很长一段时期都将产生大量的矿山地表氨氮废水，该废水的主要水质特征为有机碳源极缺、NH4+-N和NO3--N共存，废水脱氮成本高昂。以我国离子型稀土资源开采量最大的赣州市稀土矿区为例，分析了离子型稀土矿山氨氮废水的水量水质特征；比较了现有的离子型稀土矿山废水处理工程实践的工艺技术特点，并进行了理论成本分析；在分析常规厌氧氨氧化等新型生物脱氮技术在稀土矿山氨氮废水处理中的优势与不足的基础上，围绕水质特征与降低成本目标，提出了短程反硝化-短程硝化-
