摘要:

水中亚硝酸盐对人及动物有多方面的危害,离子交换、反渗透、电渗析、生物及反硝化、化学和化学催化硝化都可以从水中去除亚硝酸盐,这些方法各有优缺点.离子交换法是将亚硝酸盐集中于介质或废液中,易造成二次污染;生物法具有高效低耗的特点,但投资大;化学还原法尽管可以将亚硝酸根还原为无害的氮气,但其反应需要在较高温度下进行,效率较低.对于含量较低、处理量较少的地下深水中亚硝酸盐的处理,化学氧化法具有设备简单、处理费用低的优点.

Abstract:

Nitrite in water has many hazards to humans and animals, ion exchange, reverse osmosis, electrodialysis, biological and denitrification, chemical and chemical catalytic nitrification can remove nitrite from water, these methods have their own advantages and disadvantages. The ion exchange method concentrates nitrite in the medium or waste liquid, which is easy to cause secondary pollution; The biological method has the characteristics of high efficiency and low consumption, but the investment is large; Although chemical reduction can reduce nitrite to harmless nitrogen, its reaction needs to be carried out at higher temperatures and has low efficiency. For the treatment of nitrite in underground deep water with low content and small processing capacity, the chemical oxidation method has the advantages of simple equipment and low treatment cost.
