摘要
高盐工业废水中常含有大量盐分和难以降解的有机物,这些盐分对生化工艺中的微生物具有强烈的抑制和毒害作用,影响微生物的正常代谢和繁殖.研究发现,当废水中的盐分浓度超过3%时,生化法处理此类废水的效果将显著下降,甚至无法满足排放标准.因此,针对高盐工业废水的处理,亟待采用更高效的方法.高级氧化法通过生成具有强氧化性的自由基来降解废水中的污染物,具有处理效率高、适用范围广泛、无二次污染等优点,对于高盐工业废水的处理具有重大意义.
Abstract
High saline industrial wastewater often contains a large number of salts and hard-to-digest organic matter;these salts have a strong inhibitory and toxic effect on the biochemical process of microorganisms,and interfere with the normal metabolism and reproduction of microorganisms.It has been found that when the salt concentration in wastewater exceeds 3%,the efficiency of biochemical treatment of such wastewater is significantly reduced,and even emission standards cannot be met.Therefore,there is an urgent need to adopt more efficient methods for the treatment of high-saline industrial wastewater.The advanced oxidation method is of great significance for the treatment of high-saline industrial wastewater because it generates free radicals with strong oxidising properties to degrade the pollutants in the wastewater,and has the advantages of high treatment efficiency,wide application range and no secondary pollution.
